Introduction

This Web-based Physics Teaching material is intended to support teachers who teach physics in the early years of secondary education.
The material is designed to help teachers to gain a better understanding of physics, to use it as a reference besides the textbooks and allow them to experience for themselves the methods of teaching introduced and to develop greater confidence in their teaching of it.

It is also hoped that the material will help teachers in their continuing quest to develop new approaches to their teaching which will make physics more interesting and exciting for all their students.

The material contains facts, explanations, and sketches that will help to make the subject more interesting to student and teacher alike. This material is designed for lessons in which the primary emphasis is discovering rather than memorizing and in which teaching is by questioning rather than by telling.

The material deals with the following Units: vectors, pressure, heat and temperature, wave motion and sound. These contents are selected among the grade 9 physics textbook by expertise judgement which hinges on challenges and difficulties both for students and teachers pertinent to conceptual reasoning and understandings. Each content is divided into lessons.

Each lesson encompasses three sections:

• The starter activity relates the lesson with students daily life and experience, bringing together the overview of the chosen topic in a coherent, concise and engaging manner
• The main Activity highlights teaching and learning methods and attempts to make explicitly what students find ‘easy’ or 'difficult', clarify common students’ misconceptions . The teaching approaches provide proven teaching ideas and strategies designed to present the topic in an interesting and engaging manner
• The concluding activity includes the underlying concepts which need more attention, provide problems and exercises designed to develop the key skills and good problem solving habits.

Such materials have been chosen to address the key teaching and learning challenges; there will be no attempt to produce a complete resource material encompassing all the contents of grade 9 physics. The primary goal in producing web-based physics supporting material for secondary school teachers can be: to produce a reference  that is more focused and coherent, to provide special attention to concepts known to cause student difficulties and to support an active-learning environment
Aims

• To prompt teachers enthuse young students with the enjoyment and excitement of physics.
• To support the secondary school teachers particularly with concepts known challenging and difficult for students to learn and for teachers to teach..

The material includes several features designed to aid teacher comprehension. Each unit begins with a list of the objectives that should be achieved in that chapter. A great deal of quizzes included in each unit. These quizzes can serve as a useful self-test of comprehension. In addition, there are also end-of-chapter exercises.

It is our hope that using the web-based material will strengthen teachers’ confidence and stimulate their enthusiasm for better engagement in teaching physics.
