There may be hidden reasons that caused candidates’ failure in 2012 Agricultural Science WAEC theory, however, as pinned down by the Chief Examiner, the following are the Reasons Why Candidate Fail 2012 Agricultural Science WAEC Theory. Read on….
The candidates were unable to:
- state the meaning of soil consistency
- distinguish between primary tillage and secondary tillage
- describe methods of crop improvement such as introduction and cross breeding
- calculate the carrying capacity of the illustrated rangeland per hectare
- mention the main extension teaching methods that could be used to create awareness
- among farmers about the disease; mention the main extension teaching method that is most appropriate for creating awareness about the disease outbreak
- give reasons for the choice of the extension teaching method
- mention the problems that could be encountered in the use of the selected extension teaching method
- discuss the effects of rural-urban migration on agriculture
- suggest ways by which the problems of rural-urban migration could be solved.
Solid Recommendation by the Chief Examiner
Consequently, having identified weaknesses in the candidates’ scripts, the Chief Examiners’ recommend as follows:
- Students should be exposed to the practical aspect of agricultural science through field trips, excursions, laboratory activities and hands-on the practice of agriculture
- Agricultural science teachers should be continually trained and retrained on emerging trends in the teaching and learning of agriculture through the use of instructional materials, audio-visual aids and computer simulation of field activities not available in the local environment
- Only competent graduates of agriculture should be saddled with the teaching and assessment of learning in agricultural science
Observed Students’ Strength
Majority of the candidates showed an appreciable improvement in their ability to:
- state ways in which science and technology have contributed to agricultural development (i.e., crop protection, climatology and meteorology)
- give the functions of farm machines and implements (i.e., bulldozer, combine harvester, tractor, sprayer and planter)
- list the differences between subsistence agriculture and commercial agriculture in a tabular form
- state the advantages and disadvantages of sources of farm power (i.e., wind, internal combustion engine and electricity)
- list the methods by which soil fertility could be maintained
- explain ways in which the methods contribute to the maintenance of soil fertility
- define the term soil tillage
- outline the roles of soil management practices such as green manuring and mulching
- give reasons for carrying out irrigation in crop production
- define vegetative propagation
- give the advantages and disadvantages of vegetative propagation
- state the cultural methods used for controlling crops pests in the field
- enumerate the harmful effects of chemical pest control
- distinguish between a field pest and a storage pest
- give reasons for early harvesting of maize from the field
- list the factors that should be considered in selecting a crop variety for a locality
- state ways in which rangeland is important in livestock production
- state the benefits of management practices in animal production (i.e., dipping, vaccination and artificial insemination)
- give the advantages and disadvantages of the deep litter system of poultry management
- state reasons for carrying out animal husbandry practices such as castration of goats and creep feeding of pigs
- name local breeds of cattle reared in West Africa
- explain the term farm credit
- list sources of farm credit
- state the meaning of agricultural extension
- state demerits of cooperative societies
