Development of a course based on BEAM robots to enhance STEM learning in electrical, electronic, and mechanical domains

Table 4 Paired-sample t-test to evaluate the difference between the student pre-test and post-test

Domain	Paired differences (Shift mean)	t
Electrical	− 1.300	− 8.106
Electronic	− 1.552	− 9.423
Mechanics	− 1.200	− 3.562
Computational thinking	− 0.444	− 1.526
Recycling of WEEEs	− 1.033	− 3.439
Five domains	− 1.230	− 12.556

At the 5% significance level, the data provides sufficient evidence to conclude that the mean of the post-test is higher than the mean of the pre-test with exception computational thinking domain that presented a p > 0.05 (p = 0.065), so that there was no significant change between the pre-and post-test for this domain
