THE IMPLEMENTATION OF TEACHING MATERIAL BASED ON STEM IN FLUID FOR BIOLOGY STUDENT

Abstract

In this time, every student will need to know interdisciplinary knowledge. The purpose of this research is to develop a teaching material collaborating the understanding of physics concept about fluid topic and its application in biology based on Science, Technology, Engineering, and Mathematics (STEM) to enhance scientific literacy skills of students.  The developed teaching material has passed a validation process including content, the designed problems/questions for each subtopic and from the STEM aspect. The basic competencies that have been set are generally related to understanding the concept of static and dynamic fluid and their application in biology. For static fluid emphasizes on the physics concept in terms of pressure, Pascal's principle, buoyancy, and surface tension. Understanding these concepts are then used to analyze the phenomena of worm movement, fish buoyancy, water transport in plants, Marangoni propulsion in Microvelia insects. For dynamic fluid, it emphasizes on the concept physics such as the Bernoulli equation, viscosity, Poiseuille's law, laminar and turbulent flow. Understanding these concepts are then used to analyze the phenomenon of blood flow in humans. While for STEM, it focuses on the technique of dilating narrow blood vessels. To determine the effectiveness of the developed teaching materials, N gain analysis and student response tests were then carried out. According to N gain test, it shows an increase in scientific literacy by 0.48 due to the use of this teaching material and finally from the student response test, it shows that the developed teaching materials are feasible for use as a learning source for students
