Abstract

The study was conducted to evaluate the effectiveness of the designed microscale experiments in developing the learning outcomes of the students along the cognitive, affective and psychomotor domains. It was meant to describe and compare the learning outcomes of the students who were exposed and not exposed to microscale experiments and identified the learning experiences of the students exposed to the microscale experiments. The study used the pretest and posttest randomized control group design and subjected the experimental group to the microscale experiments and the control group to the traditional method of performing chemistry experiments. The results of the study showed that the designed microscale experiments were effective in developing the learning outcomes of the students in Chemistry. It was able to improve the learning competencies of the students in the cognitive, affective and psychomotor domain. The positive learning experiences of the students in performing microscale experiments in Chemistry accounts for the development of the students’ learning outcomes.
