Developing HOTS with VISSER: bridging the need for science instrumentation in Philippine schools

Abstract

There is a great need to improve science laboratory in the Philippines. Thus, the Versatile Instrumentation System for Science Educational and Research (VISSER) project was conceived. VISSER proposes to advance a system which can develop the higher order thinking skills or HOTS of students through laboratory activities that are essential to the development of science. VISSER likewise intends to deliver efficient, accessible and versatile solutions to perennial problems such as the lack of science equipment in laboratories through the use of a microcontroller platform, reliable sensors and educational modules. This research addresses the need to improve science laboratory activities in a classroom environment through the development of learning materials using Versatile Instrument System for Science and Technology (VISSER). Moreover, the research also proposes ways for VISSER to develop higher order thinking skills in the cognitive domain in the context of a science experiment.

Three traditional experiments were modified and tested with the use of VISSER - a microcontrolled-based platform. The study discusses how VISSER enhances higher order thinking skills in the experiments that are modified. It was concluded that higher order thinking skills (HOTS) can be developed through the use of a cost-effective yet technologically sophisticated instrumented science interface coupled with highly descriptive laboratory modules in the Philippines, as well as with other developing countries with the help of VISSER.
