Objectives And Target Learners Of This Course
This course is designed to respond to Tanzania’s public demand for their greater acquisition and application of science and technology in development work as well as public welfare and improved living conditions. Through this course students are expected to acquire theoretical knowledge and to develop and apply practical skills in chemistry. Chemical knowledge and skills should serve as tools for the achievement of national goals and objectives within the framework of the policy of Self Reliance. At the completion of their studies, students should be able to apply science principles, concepts, processes, knowledge and skills in improving the standard of life in their communities.  

Content Selection and Organization
In designing this syllabus the  fundamental concepts  and principles underlying the philosophy of education for self reliance have been observed. Also due to consideration has  been made of recent developments in the discipline, the present and future development needs of the individual learner and the general society as extrapolated from past trends, present practices and future aspirations. The content in this syllabus has been in four columns: The first column consists of major topics which are subdivided into small subtopics. The second column suggests teaching  learning strategies for each subtopics. The fourth column suggested the relevant teaching aids.

All topics and subtopics are spirally organized in order to systematically stimulate and  promote student acquisition of knowledge, understanding, skills and desirable behaviour. Also promote sensitivity about biodiversity and environmental care and management, basic needs for survival and improved lives and the role of chemical education in promoting the realization of these needs.

Choice and Use of  Instructional Study Materials.
There shall be a periodic issuance of list of approved and recommended books by the commissioner of education. Teachers are expected to guide and advise learners on  how best  to u se available books and other textual and non-textual materials provided by the schools or available in the market or in class, school or community libraries.

Methods of Teaching and Learning
The Teacher of Chemistry will be free to use any teaching method considered effective in promoting learning. It is however, worthy for the teacher to note that all professionals and experienced teachers agree that lessons succeed better if students are given an opportunity to participate actively in practicals, discussions, debates,  questioning of issues and answering questions, emulating, role playing and making critical analysis of issues and taking case studies. It will be vital for for the teacher to arrange as many practical classes as possible for the students of O-level Chemistry. Every student will be expected to develop and apply in daily life their manipulative and other skills gained from chemical science and related disciplines and professions.

Assessment of Student Progress and Perfomance.
It is expected that teachers will carry out assessment of their students progress and  perfomance periodically. This is  so as to identify their strengths and weakness and so as to help the weak and encourage the good one as appropriate

Assessment of students progress and perfomance does also measure the effectiveness of the course and the teaching/learning strategies. At the end of Form IV, students  are expected to do an overall achievement examination intended to determine the extent to which the objectives of the course have  been attained.

Instructional time.
The teacher is advised to make maximum use of  the allocated time per week for this subject. Lost instructional time for whatever cause should be compensated  for through  the teacher's own local arrangement with  the school administration. It  should be remembered that  this course of study is designed to be covered in four years at a minimum of 400 periods of forty minutes duration each.
