A Study of Titration Conception of Grade 12 Students Studied With a Virtual Experimental Program

Abstract

          The purposes of this research were 1) to develop the construction of a virtual experimental program in Chemistry Laboratory 3 on titration concept for grade 12 students, 2) to compare the titration concept of students as pre-test and post-test when studied with a virtual experimental program on titration concept for grade 12 students, 3) to study the satisfaction of those students to the virtual experimental programon titration concept for grade 12 students            
          The sample group for this study were grade 12 students in the second semester, academic year 2020 at Wat Sothon Wararam Worawihan School , one classroom that studied with a virtual experimental program , obtained by Cluster Sampling. The research instruments were 1) a  virtual experimental program on titration concept, 2) titration lesson plans, 3) titration concept  achievement tests with Reliability 0.85 based on Randomized Group, Pretest-Posttest Design. 4) students satisfaction assessment tools. Data analyzation calculated under mean, percentage, standard deviation and t-test dependent.

The research results found that titration concept of students, studied with a virtual experimental program, pre-test average score is 4.80 ,the standard deviation is 0.61 and post-test average score is 15.31 ,the standard deviation is 2.49 so post-test were higher than pre-test at statistical significance 0.05 level and satisfaction of the students to the virtual experimental program on titration  was in high level which average score is 4.48 and the standard deviation is 0.61.
