WASSCE Candidates’ Weaknesses In Applied Electricity And Remedies | Extract From Chief Examiners Report Towards WASSCE 2023
Teachers preparing students for any examination are always worried about the potential weaknesses in answers that their students will provide during the examination. Fortunately, the main examining body, the West Africa Examination Council always provide WASSCE candidates’ weaknesses in Applied Electricity during the last held examinations.
WAEC Summary of 2021 WASSCE Applied Electricity Paper Two (2)
A. A SUMMARY OF CANDIDATES’ STRENGTHS
(1) Majority of the candidates answered the question on colour coding of resistors satisfactorily.
(2) Majority of the candidates drew the phasor and wave diagrams.
(3) Majority of the candidates knew the various methods of wiring and earthing.
B. A SUMMARY OF CANDIDATES’ WEAKNESSES
(1) Majority of the candidates could not draw the diagram to explain Fleming’s left hand rule.
(2) Majority of the candidates had difficulty defining integrated circuit, listing types of it and stating its applications.
(3) Most candidates demonstrated weak knowledge in Electronics.
C. SUGGESTED REMEDIES
(1) Candidates should read more literature on Applied Electricity to improve their level of understanding of the subject.
(2) Adequate exercises should be given to students.
(3) Candidates should revise extensively before examinations are taken.
WAEC Summary of 2020 WASSCE Applied Electricity Paper Two (2)
A. SUMMARY OF CANDIDATES’ STRENGTHS
Candidates’ strengths were noted in these areas:
(1) Definition of an insulator and stating properties of a good insulator;
(2) Drawing a circuit diagram illustrating a PN junction diode connected in a reverse biased mode;
(3) Stating applications of a PN junction diode.
B. SUMMARY OF CANDIDATES’ WEAKNESSES
Candidates showed lack of in-depth knowledge in the following areas:
(1) Drawing layout diagrams of radial and ring wiring systems;
(2) Drawing and labelling the input-output (I-V) characteristics of a PN junction diode;
(3) Calculating the feedback ratio and loop gain of a non-inverting operational amplifier (op-amp);
(4) Application of Ohm’s law to solve basic electrical problems.
C. SUGGESTED REMEDIES
(1) Teachers should effectively teach students the techniques in responding to rubrics.
(2) Teachers should endeavour to complete the syllabus to adequately prepare candidates for the examination.
(3) Efforts must be made to take students on visits to industries, power stations, radio and television stations
WAEC Summary of 2021 WASSCE Applied Electricity Paper Three (3)
A. SUMMARY OF CANDIDATES’ STRENGTHS
(a) Majority of the candidates connected the circuit diagrams correctly.
(b) Most of the candidates selected suitable scales to plot their graphs.
B. SUMMARY OF CANDIDATES’ WEAKNESSES
(a) Some candidates could not determine the gradient of the graph.
(b) Some candidates reproduced the table which amounted to a waste of time.
(c) Some candidates exhibited poor pencil work.
(d) Few of the candidates commented on the graph.
- Surprisingly, a number of candidates could not multiply a constant (V2) in Question 2 by a factor.
C. SUGGESTED REMEDIES
(a) Candidates must be taught how to accurately calculate gradients.
(b) Teachers should give more practical lessons to students.
(c) Candidates must learn how to interpret graphs.
(d) Candidates should refrain from reproducing tables to save time.
(e) Candidates must be taught how to do multiplications by a factor.
WAEC Summary of 2020 WASSCE Applied Electricity Paper Three (3)
A. SUMMARY OF CANDIDATES’ STRENGTHS
(1) The majority of the candidates understood the two experiments and were able to connect the circuit diagram.
(2) Most of the candidates plotted good graphs.
(3) Candidates used good scales in plotting their graphs.
B. SUMMARY OF CANDIDATES’ WEAKNESSES
(1) Candidates wasted time by copying the circuit diagrams.
(2) Some candidates could not determine the slope of the graph.
C. SUGGESTED REMEDIES
(1) Teachers should adequately cover the teaching syllabus.
(2) Laboratories should be well equipped to enhance effective teaching and learning.
(3) Teachers should give more practical exercises to candidates to improve upon their skills.
It is the hope of our team that candidates will perform better when teachers and candidates go through this summary of strengths, WASECE candidates’ weaknesses in Applied Electricity and remedies and apply same
