Appendix 1: Teacher notes – organisation of the lesson
Teaching for electrical circuits and the lesson: Physics SHS3, Section 2, Unit 1 Deformation of solids.
This lesson, using electrical circuits links directly to SHS and the teaching and learning activities associated with it.
Ideas for organising this exemplar lesson link directly to activities and teaching examples in the OpenSTEM Africa CPD units on Using ICT to support learning, and Approaches to active notetaking.

Overview
If possible, this lesson should take place in the ICT Lab in your school if this can be arranged through your Head of Science and the Head of ICT. If the lesson takes place in the ICT Lab, it may be possible for each student to work individually at a computer; otherwise divide the class so that students are in small groups at a computer.
If it is not possible to use the ICT Lab for this lesson, then try to set up this lesson in your classroom. You may be lucky enough in your school to have a set of ‘empty’ tablets or mobile phones which students can use. Or you may be able to bring into the classroom a laptop connected to the internet or to your school intranet – and perhaps connected to a projector to make it possible for the whole class to view at once. If access to ICT is a real challenge in your school but you want your students to view an experiment, you might be able demonstrate it to small groups of your students at a time, using your own mobile phone
Whatever way(s) you set up the class, it would still be helpful to the students to be able to work in pairs or small groups for at least some of the lesson. Do remember as well that students need desk space to be able to write in their notebooks and to draw tables and diagrams.
Steps in organising the lesson
Step 1: This could take place in the classroom in the lesson preceding the one where you and your class access the OpenSTEM Africa Virtual Laboratory Electrical circuits application. Have students work in pairs to pre-read the Background section of the exemplar lesson. They need to jointly carry out the activities to identify the resistors and to calculate the value of resistance for each of the resistors. They can also ask each other the questions in the Background section and check each other’s responses. While they are doing so, you may want to walk round the class and check their laboratory notebooks, as accurate note-taking and filling in the tables is important for this exemplar lesson.
Step 2: This could also take place in the classroom in the lesson preceding the one where you and your class access the OpenSTEM Africa Virtual Laboratory Electrical circuits application. Check students’ understanding by asking them the questions in the Background section. Have each person in the pair read through the preparation for the three practical activity experiments and, if it is helpful to do so, give the class a set time to make simple diagrams of the electrical circuits. Have each student create the tables for the Practical Activity experiments with the headings specified, in their own laboratory notebook in preparation for their data collection.
Step 3: Once the students have access to the OpenSTEM Africa Virtual Laboratory, give them time to watch the introductory video and to complete the practical activity tasks in the lesson.
Step 4 Make sure that each pair has access to/can see the computer screen to begin the actual experiments. Ensure that each pair knows how to carry out the experiments – or if you are using a laptop/projector, that you draw on the expertise of the class as you go through each step of the electrical circuits experiments – e.g. ask them what the next step is.
Step 5: Have the class follow the instructions for each of the electrical circuits experiments. Make sure, if working in a pair on a PC, that each student in the pair gets to follow all the steps; if working in a group on a PC, have the group leader ensure that everyone in the group is involved.
Step 5: What they write in their tables will be agreed between the pair or within the group but allow enough time for everyone in the class to fill in their own set of tables. Have them check each other’s writing.
Step 6: Ten minutes before the end of the lesson, tell the students to complete the quiz.
