66, p ¼ 0.798 > 0.05). However, the ANCOVA results
(Geography: F 1185 ¼ 0.830, p ¼ 0.364 > 0.05; English: F 181 ¼0.038, p ¼ 0.846 > 0.05) showed that the experimental groups did not perform
significantly better than the control groups. Therefore, in response to the first research question, ANCOVA results indicate that the proposed
team-teaching model for practicing PBL in subject classes is effective in enhancing student’s learning.
