# Module Overview

### Fundamental Physics

This Stage 1 module is an introduction to physics topics such as mechanics, optics, sound, properties of materials, heat, electricity, and magnetism. It is designed to develop an understanding of these topics. This module will be taught through student-centred teaching methods such as Peer Instruction.

On successful completion of the module the learner should be able to explain certain related words and concepts, perform calculations, solve problems, apply these concepts to new problems. They should be able to present, communicate and explain their ideas and solutions by several means such as report writing and presentations. They should be able to plan and perform experiments, collect data, analyze data, present results.

The two main components of this module are written/theory and practical/laboratory

Statements about the various types of learning and teaching methods that are used in the delivery of the module:

Live lectures, pre-recorded video lectures, peer instruction, tutorials, group work, laboratory activities and online resources delivered using Brightspace.

Peer Instruction (PI) is a lecture-based teaching method that involves students being posed with a physics question (usually conceptual) during a lecture and then voting on which answer they believe is correct. The students then peer-discuss the physics involved and vote again. It is through this discussion and voting which help students to develop a mental model of the physics involved.

Laboratory skills will be developed by doing hands on experiments with feedback on skill acquisition and report writing.
