WAEC Metalwork Syllabus

1.                  PREAMBLE

The examination is designed to test candidates’ skill in basic design and practical work; their knowledge of tools, equipment and materials, and understanding of those areas of creative thinking which can be expressed and developed through planning, manufacturing and working primarily on metals as part of general education. The test will also equip candidates in the fundamentals of manufacturing to pursue higher education in science and technology.

2.                  OBJECTIVES  

Candidates will be expected to:

(a)                Observe safe working practices in the workshop.

(b)               Demonstrate knowledge and understanding of tools, materials and equipment.

(c)                Adopt basic processes for the care, repair and maintenance of hand and machine tools.

(d)               Develop their ability in identifying, analyzing and evaluating problems.

(e)                Apply their knowledge of processes and materials to the solution of problems.

(f)                Apply the principle of logical planning in the manufacture of items in the workshop.

(g)                Demonstrate basic skills of good craftsmanship.

 

3.              SCHEME OF EXAMINATION

The examination will consist of two papers – Paper 1 and 2, both of which must be taken.

Paper 1:           This will be a practical test of three hours duration.

It will consist of two (2) questions out of which candidates will be expected to answer one (1). Ten (10) minutes shall be given prior to the commencement of the examination for the study of  the drawings. Candidates will be required to make a test piece for which the appropriate drawings will be supplied. Schools will supply the materials needed. The paper carries 100 marks.

Paper 2:           This paper will be a 2½ hours theory paper consisting of two sections - A and B and will cover all aspects of the syllabus.

Section A (Objective): This will consist of 40 compulsory multiple choice (objective) questions to be answered in one (1) hour for 40 marks.

Section B (Essay-type): This will consist of five(5) essay-type questions out of which candidates will be expected to answer four (4) questions in 1½ hours. This section carries 60 marks. All questions carry equal marks.
