UPDATED WASSCE SYLLABUS FOR INTEGRATED SCIENCE AND DOCS FOR TEACHING INT. SCIENCE

Teaching integrated science requires teaching techniques as much as possible with all necessary documents.

Some Documents you shouldn’t miss when teaching Integrated science are the following

Using Just the Textbooks can make you over Teach, Non-Sylla …

Using all the Textbooks and documents without the Past Question Book, can make you miss some important things you should pay more attention to during lessons.

 

Here is the WASSCE SYLLABUS FOR INTEGRATED SCIENCE

 

1. PREAMBLE

 

 This syllabus was evolved from the teaching syllabus for the Senior High School Integrated  Science issued by the Ghana Education Service in September, 2010.

 Integrated Science seeks to equip the individual with the integrated body of scientific knowledge  and raise the level of scientific literacy of the individuals with comprehensive scientific skills that  enable them to function in the    present technological era.

  Education in science also provides opportunity for the development of positive attitudes and values.

  1. AIMS AND OBJECTIVES OF THE SYLLABUS

This syllabus seeks to among other things, enable students to:

  • Acquire the skill to solve basic problems within their immediate environment through analysis and experimentation;

 

  • Keep a proper balance of the diversity of the living and non-living things based on their interconnectedness and repeated patterns of change;

 

  • Adopt sustainable habits for managing the natural environment for humankind and

society;

 

  • Use appliances and gadgets effectively with ca lear understanding of their basic operations and underlying principles.

 

  • Explore, conserve and optimise the use of energy as an important resource for the living world;

 

  • Adopt a scientific way of life based on pragmatic observation and investigation of phenomena;

 

  • Search for solutions to problems of life recognizing the interaction of science, technology and other disciplines.

 

3.       REQUIREMENTS

 

It is presumed that candidates taking the examination must have:

 

  • Carried out activities relating to rearing of at least one of the following groups of animals:
    • chickens/ducks/turkeys
