Good feedback on a science practical report tells the learner which part of the scientific process they handled well and which part to fix next time, using the language of science. A clear rubric with separate criteria for method, results, analysis and conclusion makes that feedback quick to give and easy to act on. A single mark at the bottom of the page does neither.

Practical write-ups are where many learners lose marks they did not need to lose. They did the experiment, often carefully, but the report does not show it. Targeted feedback is how that gap closes.

## What makes practical reports hard to mark?

Reports mix several skills: following a procedure, recording data, drawing tables and graphs, explaining results and writing in precise scientific language. When you mark them as one piece, the feedback tends to be general, such as "good work" or "more detail needed", and learners do not know what to change.

Reports also come in many forms. Some are typed, many are handwritten, and diagrams are drawn by hand. Any marking approach has to cope with all of these.

## What should a practical report rubric include?

Split the report into the parts a scientist would recognise. A 30-mark rubric might look like this:

- **Aim and hypothesis** (3 marks): states what is being investigated and, where relevant, a testable prediction.
- **Method** (5 marks): clear steps another learner could repeat, with variables and safety noted.
- **Results** (7 marks): data recorded accurately in a correctly labelled table, with units; graphs where appropriate.
- **Analysis** (8 marks): describes the pattern in the data and explains it using scientific ideas.
- **Conclusion and evaluation** (4 marks): answers the aim and names at least one limitation or improvement.
- **Scientific vocabulary** (3 marks): uses the correct terms accurately.

Weight results and analysis most heavily. That is where understanding shows. Learners preparing for KCSE practical papers benefit from getting used to this kind of structure early, but your rubric should match the actual practical you set.

## How do I write feedback learners will act on?

Keep each comment tied to one criterion and one action. Compare:

- "Results need work." This tells the learner almost nothing.
- "Your table has no units in the column headings. Add cm and seconds." This can be fixed in a minute.

A useful pattern is one strength, one fix and one question. For example: "Your method is easy to follow. Label the axes on your graph. Why do you think the third reading was lower than the others?" The question pushes the learner into the analysis, which is the hardest skill to teach.

## How do I help learners use scientific vocabulary correctly?

List the key terms for each practical in the task, such as *independent variable*, *control*, *precipitate* or *diffusion*. Ask learners to use at least some of them. When marking, note which terms were used correctly, which were misused and which were missing. A short list of missing terms is a ready-made starter for the next lesson.

## How does a rubric score become a percentage?

Kenyan schools commonly report marks as percentages. The conversion from a rubric is proportional: marks earned divided by marks available, times 100. A learner with 21 out of 30 gets 70%.

Use the per-criterion scores, not just the total. Two learners on 70% might have very different needs. One may have strong results and weak analysis, the other the reverse.

## How do I mark practical reports with Korektor?

[Korektor for Kenyan teachers](https://korektor.app/ke) grades written work with AI against your rubric. It has a science report template and can check subject vocabulary and give feedback on drawings, so it suits practical write-ups.

1. Create an assignment from the science report template, or from scratch.
2. Enter the title, the task (describe the practical), the word range and the deadline.
3. Add your rubric criteria and marks, like the six above.
4. Under what the AI checks, switch on subject vocabulary and images and drawings. Add spelling and punctuation if you want them marked.
5. In the instructions for the grader, list the key terms you expect and anything specific, for example "graphs must have labelled axes with units".
6. Share the link. Learners type their name and upload a file or up to 8 photos of handwritten pages.
7. Open "received papers", review each result and adjust the mark where you disagree.

Grading takes about 20 to 60 seconds. Each result shows a percentage, a score and comment per criterion, numbered notes on the text, strengths, things to improve, the subject terms used and missing, and feedback on each image. You can download the original file and change any mark. The teacher always has the last word.

## How do I keep my professional judgement in charge?

Treat the AI as a first reader that writes careful notes. Check results where a drawing was hard to read, where a learner used an unusual but valid method, or where the mark surprises you. You know what happened in the lab, which no software does.

The first three gradings are free and need no account, so you can try one practical with a small group at [korektor.app/ke](https://korektor.app/ke) and judge for yourself whether the feedback helps your learners.
