G2 Computing Media Software is Module 5 of the 2027 Singapore-Cambridge Secondary Education Certificate (SEC), syllabus K237. Students learn to produce and edit vector graphics, raster images, presentations and videos. These skills are assessed in the electronic theory paper and the computer-based practical examination. The Media Software lab task is allocated approximately 30 marks out of Paper 2’s 80 marks, so students need working software skills, not merely knowledge of design terminology.
This guide explains how vector and raster images differ, how to work with paths, layers, object order and transparency, how to plan a presentation or short video, and how to avoid common mistakes with resolution, frames, file export and audio. It includes original practice scenarios, revision exercises, a task-checking method and FAQs. The examples are teaching exercises, not authentic or predicted SEC examination questions, and students must follow the school’s approved software and submission arrangements.

What Is Media Software in G2 Computing?
Media software allows people to create and communicate information using visual and audiovisual material. A student might design a simple symbol, edit a photograph, prepare consistent slides or assemble a short sequence of images and video clips.
A successful digital product depends on several decisions: what needs to be communicated, who will view it, which software tools are suitable, and how the finished work should be checked.
Consider a presentation explaining a school activity. A visually attractive slideshow might still fail if the text is unreadable, the images are poorly cropped or the sequence does not explain the activity clearly. Similarly, a video may contain every required clip but lose marks if its timing or soundtrack does not match the task.
G2 Media Software combines technical operations with purposeful communication.
The Official K237 Examination Structure
The 2027 K237 syllabus has six modules: Computing Fundamentals, Networking, Impact of Computing, Spreadsheets, Media Software and Programming.
Paper 1 tests knowledge and application across all six modules through 20 multiple-choice questions worth 20 marks and short structured questions worth 50 marks.
Paper 2 focuses on Modules 4, 5 and 6. It is a lab-based examination conducted on a computer, with three compulsory tasks. SEAB indicates approximate mark allocations of 30 for media, 25 for spreadsheets and 25 for programming.
The practical examination lasts two hours and fifteen minutes, including time needed to save the required files. Candidates submit soft copies of their work for marking.
These details are examination requirements; the practice examples in this guide are not promises about the actual task.
Why Media Software Is Not the Same as Art
Media Software involves visual thinking, but its assessment is part of Computing. Students may need to reproduce specified operations, create a digital artefact in the required format and demonstrate that the file works as intended.
In school Art, the assessment may emphasise personal artistic intent, experimentation and a visual portfolio. In K237 Media Software, the task may emphasise accurate software operations and meeting a digital specification.
Creativity is still useful. A good graphic should communicate effectively. But students should not prioritise artistic decoration over explicit requirements such as the correct shape, file type, text or dimensions.
The first rule is to read the specification before deciding what looks attractive.
Module 5 Has Three Main Areas
The syllabus divides Media Software into:
- 5.1 Vector Graphics: Objects created using nodes and paths; drawing, transformation, fills, outlines and shape construction.
- 5.2 Raster Graphics: Images made of pixels; file formats, resolution and image adjustments.
- 5.3 Presentations and Videos: Slide masters, storyboards, frames and assembly of visual sequences with text, transitions and sound.
The areas overlap in a real task. A vector logo may be exported as a raster image before being placed in slides. A prepared photograph may be combined with other media in a video.
Students should understand how information moves between tools, not treat each application as an isolated menu.
Vector Graphics: Shapes Defined by Paths
A vector graphic is constructed from objects described by geometric paths, nodes and related properties. Lines, curves, ellipses, polygons and text can form part of the design.
One advantage is that a vector design can generally be resized without the same pixelation associated with enlarging a low-resolution raster image.
This makes vector graphics useful for symbols, icons, simple diagrams and logos intended for different display sizes.
The syllabus expects students to create and manipulate objects, not merely define the word vector.
A learner should be able to select an object, change its geometry, adjust its appearance and understand how the result affects the whole image.
Original Vector Practice: A School Club Symbol
Imagine a fictional computing-club icon containing a circle, three simple geometric shapes and a short title. The task asks for a clear visual hierarchy, consistent colours and an export that can be used in a presentation.
Begin by identifying which objects are needed. The circle might form a background; polygons could form a symbol; the text could be placed inside or below it.
A student should be able to resize and align the objects without distorting their relationships. The order of the objects matters because one may cover another.
This is a practice design, not a specification supplied by SEAB. It is useful because one simple graphic can test many Module 5 operations.
Nodes and Paths: The Structure Behind a Shape
Nodes define important positions on a vector path. Handles may influence the direction or curvature of the path between nodes.
For example, a curved leaf-like form may begin as a simple path with several nodes. Adjusting a handle changes the curve without requiring the student to draw the entire object again.
The syllabus includes direct manipulation of nodes and node handles. Students should practise changing the shape intentionally, not drag points randomly until the result looks acceptable.
A useful exercise asks the student to predict what moving a particular handle will do, then test the prediction.
This connects visual editing with a general computing habit: make one controlled change and observe its effect.
Move, Resize, Rotate and Flip
These operations change different properties.
Move changes an object’s location. Resize changes its dimensions. Rotate changes its orientation around a relevant centre. Flip reflects it horizontally or vertically.
A student who needs a mirrored pair of shapes should not assume that rotating one shape by 180 degrees creates an exact reflection. In many cases, reflection and rotation produce different arrangements.
When a task specifies a direction or alignment, the chosen operation should match the requirement.
A strong learner identifies the intended transformation before opening a menu.
Front-to-Back Arrangement: Understanding Object Order
Digital drawing tools often stack objects in an order. A later object may appear in front of an earlier object unless the order is changed.
Suppose the practice club logo contains a large background circle, a star and a title. If the circle appears on top, it may hide the star and text.
The solution is not always to delete and redraw the circle. It may be to change the front-to-back order.
The syllabus specifically includes setting object arrangement. Students should practise bringing objects forward and sending them backward while checking the final appearance.
Layer order is a relationship among objects, not just an aesthetic preference.
Group and Ungroup: Editing Several Objects Together
Grouping allows multiple objects to behave as one unit for certain transformations. This is useful when a symbol contains several shapes that should move together.
Ungrouping allows the individual elements to be edited again.
A common mistake is to group objects before all details are correct and then struggle to select the one that needs changing. Another is to leave an intended group ungrouped and accidentally move only one component.
An effective workflow uses grouping for coordination and ungrouping when individual editing is needed, according to the task and software.
The student should check whether all intended objects are included.
Fills: Solid, Gradient and Pattern
SEAB lists solid fills, gradient fills and pattern fills.
A solid fill uses a specified colour. A gradient changes between colours or tones. A pattern fill repeats a design or texture.
These choices can support visual hierarchy. For example, a solid background may make text easier to read, while a complex pattern can reduce contrast.
Students need to set the specified colour and style when instructed. An attractive alternative may still fail the task if the question requires a particular fill.
The appropriate choice depends on readability, consistency and specification, not only personal taste.
Transparency: Seeing Through Objects
Transparency allows an object underneath another to remain visible.
In an original practice exercise, a partially transparent blue rectangle overlaps a yellow circle. The viewer can see both objects in the overlap region.
This is different from choosing a pale solid colour that happens to resemble a transparent effect. The underlying objects should actually show through according to the set transparency.
Students should check that the software applies the effect to the intended object and does not make crucial text unreadable.
Transparency is useful when it communicates layering; it should not obscure the message.
Outlines: Colour and Thickness Matter
The syllabus includes setting an object’s outline with a specified colour and thickness.
An outline can separate similar-coloured shapes or draw attention to one feature. A thick outline might make a small icon easier to see but also distort a delicate design.
A task may require a particular width or colour, so students should inspect those settings rather than estimate by eye.
If the result looks wrong, check whether the adjustment affected the outline or the fill. They are different object properties.
This distinction is simple but important in software applications.
Text Along a Curved Path
Vector software can attach text to a curve so the words follow the path’s shape.
A practice icon might have the club title arranged around part of a circle. The student must choose a suitable curve and ensure the text stays legible.
Common errors include reversing the text direction, placing it too close to another object or using a curve so tight that letters overlap.
This feature should be used when requested or useful, not as unnecessary decoration in every graphic.
A student should check the final result at the intended viewing size.
Shape Merging: Five Different Operations
The official K237 syllabus lists union, intersect, fragment, subtract and combine as vector shape-merging operations.
These are related but not interchangeable.
In a common vector workflow, union combines overlapping shapes into one silhouette, while intersection keeps the shared overlapping region. Subtraction removes one shape’s region from another. Fragmenting divides shapes into separate regions, while combining produces a composite path according to the software’s behaviour.
The exact output and commands can vary by application, so students should follow their school’s approved tool and task requirements.
The best practice uses two simple overlapping circles or rectangles, predicts the result and compares the actual shape after each operation.
Original Shape-Merging Exercise
Draw a large rectangle and a smaller circle that partly overlaps its edge.
For a union practice, predict the outline of the combined shape. For intersection, identify the area common to both. For subtraction, decide which object must cut a region from which other object.
The important concept is the geometry of the resulting region. Choosing the right command requires understanding the relation between the input shapes.
Students should save separate versions during practice so they can compare the operations. Do not assume an irreversible edit can always be undone after closing a file.
This exercise teaches vector logic rather than artistic style.
Exporting Vector Art as Raster
The syllabus includes exporting vector graphics as raster images.
An export converts an editable path-based design into a pixel-based result at a chosen size or resolution. The raster export may be appropriate for a presentation, video or image submission.
But an exported PNG is not automatically the same as the original editable vector file. The student may need to preserve the source version for later changes.
Before exporting, check the required dimensions, background, transparency and file type.
After exporting, open the resulting file to confirm that the appearance matches what the task requires.
A successful export is a tested output, not merely a click on the Export command.
Raster Graphics: Images Made of Pixels
A raster image consists of individually coloured pixels arranged in a grid.
Photographs are commonly raster images. Enlarging a small image beyond its useful resolution can make pixel boundaries or soft edges more noticeable.
The syllabus includes common formats such as PNG, GIF, TIFF, BMP and JPEG, together with the question of whether each can support transparency.
It also requires understanding image resolution and editing operations such as sharpness, brightness, contrast, cropping and resizing.
The practical skill is knowing what each change does and whether it preserves the intended information.
Raster Versus Vector: A Clear Comparison
| Feature | Vector graphics | Raster graphics |
|---|---|---|
| Main structure | Nodes and paths | Coloured pixels |
| Typical task | Icon, symbol, scalable diagram | Photograph, pixel-based artwork |
| Resizing | Can generally scale without pixelation | Large enlargement may reduce apparent quality |
| Editing | Adjust paths and object properties | Adjust or replace pixel information |
| Export | May be converted to raster | Already pixel-based |
This is a teaching summary. Real digital workflows can combine both types, and export settings affect the final result.
Students should not confuse a file’s visible appearance with the method by which its image data are represented.
Understanding Image Formats Without Memorising Myths
PNG, JPEG, GIF, TIFF and BMP do not all provide identical features.
PNG commonly supports transparency and lossless image storage, making it useful for graphics with clear edges. JPEG generally does not support an alpha transparency channel and is widely used for photographs. GIF supports limited palette colours and simple transparency, while TIFF and some BMP variations have format-specific capabilities that depend on software and implementation.
The exact K237 requirement is to recognise the named formats and understand whether transparency is supported for each. Students should practise using the school’s definitions and applications.
Avoid assuming that every file with the same extension behaves identically in every program.
An exported image should be checked for the transparency and appearance required by the task.
Resolution, DPI and PPI
The syllabus discusses output resolution in dots per inch (dpi) for printing and pixels per inch (ppi) for image display.
The important distinction is between the number of pixels in an image, the intended output dimensions, and how densely those pixels are displayed or printed.
A 600-by-600-pixel image contains 360,000 pixels. Labelling it with a higher ppi value does not magically create more image detail.
If the image is enlarged substantially, its existing pixels must cover more space and may look less sharp.
Students should learn the relationship rather than memorise that one number always means “good quality”.
Original Resolution Example
A fictional task supplies a raster icon measuring 400 × 400 pixels and asks for a version displayed at 800 × 800 pixels.
The enlarged image has four times as many pixel positions in its new dimensions, but the original source did not contain four times as much detailed information.
Depending on the resize method, the program estimates new pixel values. The image may appear softer or more pixelated.
A useful quality check compares edges and small text before and after resizing. If the image becomes visibly poor, returning to a suitable higher-resolution source or recreating a vector version may be more appropriate.
The goal is to select a suitable source, not repeatedly enlarge a damaged file.
Crop and Resize Are Different Operations
Cropping removes parts of the image outside a selected area. Resizing changes the pixel dimensions or displayed size of the image.
Suppose a photograph shows a student at a desk with large empty areas on both sides. Cropping may focus attention on the student without changing the scale of the remaining pixels initially.
Resizing the whole image changes the dimensions but does not automatically remove the empty areas.
A task asking for a tighter composition requires cropping, not simply making the picture smaller.
Students should check whether the requested aspect ratio or final dimensions must be preserved.
Brightness, Contrast and Sharpness
Brightness changes the overall lightness of an image. Contrast changes the separation between lighter and darker regions. Sharpness adjustments can emphasise boundaries or local detail.
Increasing all three sliders to maximum rarely produces a good result. Brightness may wash out highlights; contrast may hide shadow detail; excessive sharpening can create visible halos.
A strong learner makes a deliberate adjustment and compares the output to the task.
During practice, use the same image to understand one change at a time. Save a copy of the original before making irreversible edits when permitted by the workflow.
The objective is readable, accurate visual communication, not dramatic processing.
An Original Raster Editing Task
Fictional brief: A school club needs a landscape photo for one presentation slide. The image has distracting empty space, slightly dark shadows and a small label in a corner.
The student should first identify the required crop and final dimensions. Next, adjust brightness or contrast only if the subject benefits. Then check whether the label remains legible or needs a different placement.
The task is not to delete real people or alter evidence to make an event look different. Image editing should be honest about what is being presented.
The result should be inspected at the slide’s actual viewing size, not only in a zoomed editing window.
Slide Masters: Consistency Across a Presentation
K237 includes use of the slide master feature for consistent style and layout.
A slide master allows repeated formatting elements, such as fonts, titles, colours and placement rules, to remain consistent across multiple slides.
Without this approach, a student may spend time formatting each slide separately and introduce accidental differences.
The benefit is not only appearance. Consistency helps the viewer recognise the hierarchy of information and follow the presentation.
However, a master layout cannot rescue slides whose content is inaccurate or whose text is too dense.
Storyboards: Plan the Message Before the Slides
The syllabus requires producing slide presentations based on storyboards.
A storyboard maps the intended sequence of scenes or slides and the role of each. It may include a rough visual arrangement, text to be shown and transitions between ideas.
For a presentation about a fictional school event, the storyboard might include purpose, programme, participation details, safety or requirements, and closing action.
The task should guide the structure. Adding twenty extra slides that repeat the same idea does not automatically improve communication.
A clear storyboard helps students detect missing information before investing time in software formatting.
Original Storyboard Exercise: A School Reading Event
Imagine an original practice brief for a five-slide presentation encouraging students to join a reading activity.
| Slide | Purpose | Main visual or message |
|---|---|---|
| 1 | Introduce the activity | Clear title and a relevant graphic |
| 2 | Explain what participants do | Short process illustration |
| 3 | Show possible benefits | Two distinct ideas with examples |
| 4 | Give practical information | Fictional date, place and conditions |
| 5 | Explain the next step | Clear invitation or action |
The dates and event are hypothetical. Students should not present them as details of a real school announcement.
A useful practical task is to create the storyboard first, then produce slides using a consistent master style and appropriate media.
A Good Slide Does Not Need a Wall of Text
Students sometimes paste an entire essay onto each slide. The result may satisfy the desire to include information but make the presentation hard to read.
A slide should present the information needed at that moment, with clear hierarchy and legible text.
A photograph or icon should support the message, not compete with it. Too many decorative transitions can distract from the content.
Students should learn to distinguish presentation content from speaker notes or supporting explanation, depending on the task and software.
The best slide makes a point understandable at the intended viewing distance.
Video: A Sequence of Frames
The syllabus says that frames are individual images within a video.
A video shows a sequence of frames over time. Frame rate, measured in frames per second, affects how motion is represented.
For example, a ten-second clip at 25 frames per second contains approximately 250 frames. At 50 frames per second, a ten-second clip contains approximately 500 frames.
Higher frame rates may provide smoother motion, especially for certain movement, but can require more storage or processing resources depending on encoding and settings.
SEAB specifically includes the relationship between frame rate, smoothness and file size. Students should describe it with appropriate qualification, not claim that file size always doubles exactly.
Why Video Size Is Not Determined by Frame Rate Alone
Frame rate matters, but actual file size also depends on duration, resolution, compression, bitrate, content complexity and audio.
Two videos of equal duration and frame rate can differ greatly in size if their encoding settings differ.
Students should therefore avoid rules such as “twice the frame rate always means precisely twice the file size”. The syllabus states that a higher frame rate may occupy more space and may appear smoother.
The word “may” matters because digital systems involve several interacting settings.
The examination task may specify output requirements; those control the candidate’s choices.
A Video Timeline: Put Events in the Right Order
Video-editing software uses a timeline or similar representation to arrange clips, images, text and audio over time.
In an original practice video explaining the fictional reading event, the sequence might begin with the activity’s title, show participants’ tasks, explain the schedule and end with a call to action.
An incorrect sequence could display the event conclusion before introducing the activity, confusing the viewer.
Students should use the storyboard to guide the timeline and check both content order and timing.
The final video is the result of a communication plan translated into a timed sequence.
Combining Still Images and Video Clips
K237 requires creating a video from still images and video clips, with text, transitions and sound.
Still images can be displayed for a chosen duration. Video clips contain their own moving frames. Combining them requires decisions about relative pacing and what the viewer should notice.
A photo held too briefly may be unreadable. A short clip extended too much may make the sequence feel slow or repetitive.
Students should follow the task specification and review the playback rather than assume the timeline will look correct when exported.
A technically successful edit should still be understandable to the intended audience.
Text Overlay: Readability Is a Technical Requirement
Text on a video can supply titles, labels or instructions. But text must remain legible against its background for an appropriate duration.
A pale title over a bright image may be difficult to see. A label placed too close to the edge may be cut off in some viewing situations.
Useful solutions may include changing placement, selecting a suitable contrasting colour or using a clear background shape where permitted.
The aim is to make the text readable and purposeful, not simply to demonstrate that the software’s text tool exists.
Always check the exported result, because display conditions may differ from the editing preview.
Transitions: Why More Is Not Always Better
A transition changes the viewer from one scene or slide to the next. Simple cuts, fades and other effects can help control the flow.
Excessive transitions can distract from the content or make a short video feel fragmented. Some effects may also obscure important text or movement.
A learner should ask what a transition contributes: Does it indicate a change of section, passage of time or relationship between ideas?
If it serves no communicative purpose, a simpler choice may be more effective.
The examination may require a particular transition type, in which case the specification takes priority over style preference.
Sound: Audio Needs the Same Care as Images
Sound can support explanation, atmosphere and pacing. But the student should consider its volume, timing, intelligibility and relationship to the visuals.
A background track that overwhelms spoken narration makes the presentation less useful. A sound effect arriving after the related event may appear accidental.
The student should listen through the complete exported video, not just inspect the visual timeline.
Where music or third-party audio is used, follow copyright, attribution and school policy. Do not assume that audio found online is automatically free to reuse.
Responsible media production is part of Computing’s broader concern with the impact and ethical use of technology.
Editing Audio: Basic Practical Habits
Audio may need appropriate trimming, placement or volume adjustment to fit the task.
A clip can begin with an unintended pause, contain an abrupt ending or become too loud relative to narration. Students should test these aspects in the permitted software.
Be careful not to alter recordings in ways that misrepresent what someone said or create false evidence about a real person.
For revision, use original, authorised recordings and fictional event information. This makes it possible to practise editing without privacy or copyright complications.
An effective final check includes watching and listening from beginning to end.
Exporting the Final Video
The editing project may contain editable source files, while the submitted video is an exported output in the format specified by the task.
Before exporting, check the intended resolution, duration, frame rate, soundtrack and text. Then verify the output file actually exists.
After exporting, play it. A video may appear correct inside the editor but export with missing audio, a changed crop or an unintended blank frame.
The examination requires the specific soft copies stated in the paper, not whatever filename or extension a student prefers.
The time to save the files is already part of Paper 2’s 2 hour 15 minute duration.
The Source File Is Not Always the Final Output
An editable vector drawing, image-editing document, slide deck or video timeline may contain layers and settings not present in a final export.
A raster image exported from vector artwork may look identical on screen but no longer contain editable nodes and paths. A rendered video may play correctly but not allow the original transitions to be changed without its editing project.
Students should therefore distinguish working files from exported files, following the question’s submission instructions.
Do not delete source materials prematurely during practice if they are needed for later editing.
A correct filename is not proof of a correct file. Open and check the actual contents.
A Complete Original Practice Project
Fictional task: Produce a small set of media to explain a school recycling activity. The exercise requires a vector symbol, one edited photograph, four consistent slides and a short video.
The student first identifies the intended audience and essential information. Then they sketch a vector symbol using simple shapes and a short title. They edit a permitted photograph to an appropriate crop and readable brightness.
Next they use a slide master to keep typography consistent, following a short storyboard. Finally they assemble a video from approved stills and clips, adding readable labels, modest transitions and correctly controlled audio.
This exercise is an integrated learning project, not a K237 past paper. It tests the relationship between tools and communication.
The best result is accurate, usable and correctly saved, rather than merely visually impressive.
How to Diagnose a Poor Vector Export
If an exported icon looks fuzzy, check whether the raster export’s dimensions were suitable for the intended display.
If the background is unexpectedly solid rather than transparent, inspect the format and alpha settings. If some objects are missing, inspect the original object order, hidden elements and export area.
If curved text appears detached from its path, review the source design and how the chosen software handles the text during export.
Do not repair every problem by repeatedly making the output larger. Identify which stage introduced the problem.
A good correction is testable and specific.
How to Diagnose an Unclear Presentation
Ask whether the problem lies in the content, storyboard, layout or visual assets.
If the audience cannot understand the order of events, rearranging one image will not necessarily fix the storyboard. If text is unreadable, adding more slides will not solve the contrast problem.
A teacher should diagnose the first failure and provide a small new task that tests the correction.
Students become more independent when they can name the cause of an error rather than ask which button to click.
How to Diagnose Video Playback Problems
A missing opening frame may be a timeline or export-range problem. Silent playback may involve missing audio, muted tracks or output settings. Unreadable captions may involve contrast, size or timing.
The right repair depends on the observed symptom and the approved software.
Students should practise a preview → export → playback → compare with brief cycle. Do not assume successful rendering means every requirement has been satisfied.
During examinations, follow the centre’s instructions if software malfunctions; do not experiment with unauthorised system changes.
Common Error 1: Confusing Vector and Raster
The student expects a small raster photograph to enlarge as cleanly as a vector symbol.
Repair by examining paths versus pixels and testing appropriate source size.
Common Error 2: Wrong Object Order
A background covers important text or shapes.
Repair by adjusting front-to-back order rather than unnecessarily redrawing the artwork.
Common Error 3: Grouping the Wrong Objects
A title moves independently of the symbol that should stay aligned with it.
Repair by checking which components belong in the group.
Common Error 4: Choosing the Wrong Shape Operation
Subtraction is used when the task requires an intersection or union.
Repair through a two-shape practice exercise and predicted output.
Common Error 5: False Transparency
An exported background looks white although the task requires actual transparent pixels.
Repair by using a suitable format and verifying the exported image.
Common Error 6: Excessive Image Adjustments
Brightness and sharpening are pushed too far, reducing visible detail.
Repair by making one controlled adjustment and comparing the result with the source.
Common Error 7: Inconsistent Slide Layouts
Every slide has a different title location, font and spacing.
Repair by using a consistent master style and a purposeful storyboard.
Common Error 8: Text Overlaid Without Contrast
The viewer cannot read a title against a complex background.
Repair by changing placement or contrast while preserving the required design.
Common Error 9: Video Frame Rate Misunderstood
The learner assumes higher frame rate always guarantees a smaller, sharper file.
Repair by distinguishing frame rate, resolution, bitrate and encoding.
Common Error 10: Sound Covers Narration
The music is so loud that spoken information is difficult to hear.
Repair by checking audio levels and listening to the exported result.
Common Error 11: Source File Is Submitted Instead of Required Output
The student saves only the editable project when the task requires an exported image or video, or vice versa.
Repair by reading the submission requirements and checking every specified file.
Common Error 12: The Final File Is Not Saved
The practical work is complete inside the application, but the required soft copy cannot be found.
Repair by rehearsing the authorised file location, naming and save-check procedure in timed practice.
The Fencing Method for Media Software
The eduKateSG Fencing Method begins with one small, observable skill and introduces a new condition at each step.
For vector graphics, start by creating two shapes. Next practise position and overlap, then grouping, then fills, transparency and a shape-merging operation.
For raster graphics, begin with a crop, then resize, then tonal adjustments, comparing each change with the original.
For video, begin with a simple sequence of two still images. Add a caption, a transition and a short original audio clip only after the earlier stage works.
Finally, give a different design brief without naming the tool. The student should select the suitable operation independently.
A Four-Week K237 Media Revision Plan
Week 1: Vector Foundations
Practise nodes, paths, shapes, transformations, object order and grouping. Predict the outcome of union, intersection and subtraction on simple shapes.
Week 2: Raster Images
Compare PNG and JPEG use, study resolution and transparency, and practise resizing, cropping and adjusting image appearance without distorting meaning.
Week 3: Presentations and Storyboards
Plan a short fictional communication task, use a slide master, and create consistent slides with appropriate text and visuals. Check whether the presentation serves its audience.
Week 4: Video and Export
Assemble an original short video using authorised media, text, transitions and sound. Test frame rate concepts, preview the result, export and verify every required soft copy.
A four-week cycle is a starting routine, not a promise of mastery or an attempt to predict the Paper 2 task.
What Parents and Tutors Can Do
Parents can ask the student “Why did you choose a vector rather than a photograph?”, “Which object is in front?”, “What does the viewer need to see first?”, and “Did the exported file actually work?”
These questions focus on the reasoning behind software decisions instead of memorising interface buttons.
Encourage the use of original or properly licensed media and avoid uploading confidential school or personal information into unapproved applications.
eduKateSG’s broader 3-pax small-group instruction model values individual feedback, but Computing practical preparation should match the software, facilities and rules authorised by the student’s school. Additional tuition is not automatically required when regular classroom practice is effective.

Final Takeaway: Build Media That Works and Communicates
G2 Computing Media Software is an applied skill. Students must understand why a graphic is vector or raster, how its objects and pixels are edited, and how images, slides, video and sound communicate a message.
