Abdulqadir Mohamad Suleiman. (2016). Concept Attainment Teaching Methodology (CATM) – An Effective Approach for Training Workers on Chemicals Health Hazards. Universal Journal of Educational Research 4(11): 2677-2685. https://doi.org/10.13189/ujer.2016.041122

q2 · i? · causal · r1

Comparison of the trained experimental group with a control group (n=31) of certified cleaners and supervisors: CG mean 17.10%, close to the EG pre-tests; trained workers scored 3.17 and 3.64 times better on post-test2. Descriptive comparison; no significance test printed for this contrast.

"The CG had a mean score of 17.10% (S.D. 14.54) which was quite close to the Pre-tests, but lower than Post-tests 1 and 2 of the EG. Comparing the mean score Post-test2 to that of the CG, the trained cleaners had in the first period a 3.17 times better performance than the CG, while the second period was 3.64 times better."
