Abstract

This descriptive-qualitative study determined student performances on the basic concepts of fluid mechanics before and after using locally made set-ups in inexpensive demonstrations and experiments. The set-ups and questionnaires were utilized and validated and the hypothesis was tested using accuracy, standard deviation, mean, and t-test for dependent data. Results showed that measurements obtained from the locally made set-ups were close to the accepted value and not scattered and were able to exhibit the theory of each concept; however, systematic and random errors may have occurred during the conduct of the experiment. Moreover, the study revealed that a significant difference exists between the students’ pretest and posttest performances and implied that utilization of the localized set-ups enabled the students to remember, understand, apply, and analyze the basic concepts of fluid mechanics that made them obtained better scores in the posttest.
