This study was aimed at finding out if the level of performance of selected Jamaican Grade 12 students on an achievement test on the concept of genetics was satisfactory; if there were statistically significant differences in their performance on the concept linked to their gender, self-esteem, cognitive abilities in biology, school-type and…

Conducted a study that used concept maps to compare and evaluate how the principal concepts of respiration were elaborated in three high school biology textbooks specifically written for the English-speaking Caribbean nations. Discusses concept analysis, elaborations, and defects in the elaborations. (19 references) (JRH)

This study determined Jamaican high school students' (n=305) level of performance on five integrated science process skills with performance linked to gender, grade level, school location, school type, student type, and socio-economic background (SEB). Statistically significant differences in performance based on grade level, school type, student…

This study was designed to ascertain if (a) the level of biology performance of the selected 393 Jamaican 11th-graders (188 boys, 205 girls)--who constituted the main study's sample--was satisfactory or not; (b) there were statistically significant differences in their performance linked to their gender, attitudes towards biology, learning styles,…

This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean = 28 or 70% and above) or not (less than 70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities…

The types of assessment methods that 400 Jamaican primary teachers indicated that they used in teaching science were analyzed using three instruments. Most of the teachers indicated that they often used oral quiz and other traditional assessment methods (TAM) while alternative assessment methods (AAM) were rarely used. An oral quiz was often used…

Verified the efficacy of concept and Vee mapping heuristics under cooperative, cooperative-competitive, and individualistic whole-class learning conditions in improving (n=808) eighth graders' achievement in ecology and genetics. Experimental groups achieved significantly better than the control groups; students in cooperative-competitive…
