Design
The quasi-experimental method involved creating two groups: one experimental and one control, with the experimental group using Blackboard collaborative breakout groups and the control group relying exclusively on online lectures and continuing with the same method without breakout groups. To determine the extent of the continuity of the impact of Blackboard collaborative breakout groups, the post-test was administered to the two groups immediately following the completion of the teaching and learning processes, while the follow-up test was administered after no further teaching and learning processes had taken place for a month.
