Subclaims¶

q2 i? Case-based learning (adjusted mean 9.49) significantly outperformed the control group (7.50), and the 7E learning cycle group (8.40) also significantly outperformed the control group, per Scheffé post-hoc tests at p < .05. → Adesoji 2015 q2 i? The order of decreasing achievement means was case-based > 7E learning cycle > control. → Adesoji 2015 (2)

q2 · i? · causal · r2

Scheffé multiple range tests of achievement by treatment in the quasi-experiment; Table 4 marks all pairs of groups significantly different at p<.05, with means 9.49 (case-based), 8.40 (7E), 7.50 (conventional).

"Table 4 shows a significant effect of treatment on students' achievement in chemistry."

q2 · i? · causal · r2

Multiple classification analysis of achievement scores (grand mean 8.47) reports case-based learning obtained the highest scores (9.49), followed by 7E (8.40) and conventional (7.50); the article states CBL "was more effective than the 7E learning cycle and the conventional method."

"The order of decreasing magni tude of the chemistry achievement mean scores of the groups is represented as case -based > 7E learning cycle > control."

Discussion¶

Related Claims¶

• Case-based learning yielded the highest attitude mean score, significantly above conventional teaching, but the 7E-versus-CBL attitude difference was not significant — related
• Treatment (7E learning cycle, case-based learning, or conventional teaching) has a significant main effect on senior secondary students' chemistry achievement — a broader claim this one bears on
