Active Learning for Computer Engineering students: An experimental approach

An experimental research method using a single group with a pre-test and post-test was conducted to introduce Active Learning to a class of 33 Computer Engineering students. The researcher developed instructional materials consisted of a pre-fabricated Printed Circuit Board (PCB), and Manual that were designed to demonstrate the Basic Logic Gates functions: AND, OR, NOT, NAND, NOR, XOR, and XNOR. Students were given exam to test their knowledge of the Basic Logic Gates prior to experiment and results showed that students did not have background on the subject. Lecture method was conducted during the first two weeks of classes. The different logic gates, their logic functions, diagrams, and truth tables were discussed. The pre-test was conducted and the results showed a mean distribution score of 5.79, with a standard deviation of 5.787. Students were then asked to use the Active Learning materials (PCB and Manual). Students were asked to assemble the PCB using the guide included in the Manual, and perform the experiments on their own using their assembled PCB. After one month, students were given a post-test. Results of the study showed a mean distribution score of 29.91, with a standard deviation of 7.539. The z-test for correlated samples @0.05 level (z = 13.797, Zcv = ± 1.96) indicates that there is significant improvement in the performance of the students during the post-test. Students were asked to evaluate the materials they used and the mean distribution scores suggests that students had improved understanding of the concepts through the use of the materials.
