TO STUDY THE LEARNING EFFICIENCY OF MATTHAYOMSUKSA 6 BY INQUIRY APPROACH WITH DEMONSTRATION OF WIND FLOW THROUGH A PIPE ACCORDING TO THE CONTINUITY EQUATION

Abstract

In this research, the purpose are 1) to study the learning efficiency of students who have learning
a demonstration of wind flow through the PVC pipe by the air in accordance with the principle of continuity
equation and 2) to measure the satisfaction of student for inquiry approach (5Es) using a series of
a demonstration of fluid flow through the PVC pipe by the air in accordance with the principle of continuity
equation. The sample used in this study was Matthayomsuksa 6’s students Learning Science-Mathematics,
Semester 1/2561 of Phopphrawittayakom school ; 27 people. Tool used to collect information included
lesson plans for teachers Inquiry (5Es) using a series of demonstration set air through pipes in different sizes
according to the principle of continuity, pre-post test and satisfication survey. The statistic was used by
means, standard deviation and normalized gain. The results were shows the following : 1) The wind flew
through the PVC pipe and the diameter 0.106, 0.083 and 0.071 meter. The surface area of the pipe has
a Thermoelectric 12V 6A attached to a heat lamp set using Alcohol Burner. The distance between the
Thermoelectric base was equal to 0.2 meter. Observed brightness measuring the voltage of the LED Portable
USB with a multimeter was 1.04 V and the electrical current was 0.75 A 2) Learning to progress <g> of
27 students was medium. And 3) The satisfaction of the inquiry approach (5Es) using a series of a
demonstration of fluid flow through the PVC pipe by the air in accordance with the principle of continuity
equation and demonstration experiment were the highest level of content satisfaction and very high,
respectively.
