032 CHEMISTRY

(For Both School and Private Candidates)

1.0 INTRODUCTION

This examination format is a revised version of the 2008 format issued by the National Examinations Council of Tanzania (NECTA).

The format is based on the 2010 syllabus. The current format emphasizes on competence based assessment that will require candidates to think critically and creatively.

However, there are no changes made to the examination content.

2.0 GENERAL OBJECTIVES

The examination will assess the extent to which candidates are able to:

2.1 apply chemistry knowledge, skills and principles in everyday life activities;

2.2 design and perform experiments;

2.3 use symbols, formulae and equations to communicate in chemistry; and

2.4 apply the scientific principles and knowledge in exploitation of natural resources with conservation of the environment.

3.0 GENERAL COMPETENCES

The examination will specifically test the candidates’ ability to:

3.1 use chemistry knowledge, skills and principles in solving daily life problems;

3.2 apply knowledge on chemistry in doing various activities and/ or experiments;

3.3 apply chemical symbols, formulae and equations to communicate in chemistry; and

3.4 use scientific and technological skills in conserving and making sustainable use of the environment.

4.0 EXAMINATION RUBRIC

The examination will consist of two papers. Paper 1 (032/1 Chemistry 1 Paper) and Paper 2 (032/2 Chemistry 2 Paper).

4.1 032/1 Chemistry 1

This will be a theory paper of three (3) hours. The paper will consist of sections A, B and C with a total of 14 questions.

Candidates will be required to answer a total of 13 questions which will weigh 100 marks.

<> Section A will consist of two (2) questions. One question will be a multiple choice with 10 items carrying one (1) mark each. Another question will consist of five (5) matching items carrying one (1) mark each. Candidates will be required to answer both questions.

This section will weigh a total of 15 marks.

<> Section B will consist of 10 short answer questions, each carrying seven (7) marks. Candidates will be required to answer all the questions. This section will weigh a total of 70 marks.

<>  Section C will consist of two (2) questions which will either be essay or structured questions, each carrying 15 marks. Candidates will be required to answer only one (1) question.

4.2 032/2 Chemistry 2

This paper will either be Actual Practical or Alternative to Practical. Three equivalent alternatives of the actual practical paper (032/2A Chemistry 2A, 032/2B Chemistry 2B and 032/2C Chemistry 2C) will be set. Only one alternative to practical paper (032/2 Chemistry

2) will be set. Candidates will be required to sit for either the actual practical or the alternative to practical paper. The actual practical paper will be for 2½ hours.

This paper will consist of two (2) questions. Candidates will be required to answer all the questions. Each question will carry 25 marks, making a total of 50 marks.

The alternative to practical paper will be of 2½ hours. This paper will consist of five (5) questions. Candidates will be required to answer all the questions. Each question will carry 10 marks, making a total of 50 marks.

Note

(i) The actual practical paper will have more than one alternative paper which will be sent to schools depending on the number of candidates. Alternative A will be sent to schools with up to 100 candidates, alternatives A and B to schools with candidates up to 200 and alternatives A, B and C to schools with more than 200 candidates.

(ii) A check-list of apparatuses and chemicals required for the examination will be sent to schools not less than three months before the date of sitting for the actual practical paper.

However, 24 Hours Advance Instructions will be dispatched in advance for opening 24 hours before the beginning of the examinations for laboratory arrangements to be made.
