Principle: The study examined the effectiveness of collaborative learning while enhancing drill and practice skills and critical-thinking skills among college students as it relates to technology.
Type of Design: Subjects studied two undergraduate classes of students enrolled in an industrial technology course. Each class consisted of twenty-four students. One section of the class was randomly assigned to individual learning group while the other section was assigned to collaborative learning.
Independent variables: The treatment group consisted of two parts: lecture and worksheet.
Dependent variables: The pre- test was conducted to assess prior knowledge and the post-test was used to measure the treatment effect.
Procedure: Both groups were simultaneously introduced to a fifty-minute lecture. After hearing the lesson one section of students were randomly selected to participate in an individual learning group while the other section was assigned to the collaborative learning group. A worksheet, which consisted of both drill and practice and critical thinking items, was given to both groups.
Individual learning: The students were given 30 minutes to answer the worksheet. After the allotted time was over students were given fifteen minutes to compare their answers to an answer sheet. Lastly they were administered a posttest.
Collaborative learning: Students were given thirty minutes to solve the same worksheet and encouraged to discuss problem solutions. After the allotted time fifteen more minutes were given for group members to discussed their answers with other groups. Lastly they were administered a test post test.
Results: Students who participate in collaborative learning did better with the critical thinking. Each group did equally well on the drill and practice test.
Comments: The benefits of working on collaborative groups in this day and time are very beneficial especially in this day and time. More undergraduate students should have the opportunities to work in these setting.
