Abstract

The purpose of this experimental research aimed to 1.) effectively enhance the virtual laboratory learning in acid-base solution lesson 2.) study the learning achievement of mathayomsuksa 1 students before and after using the virtual laboratory learning in acid and base solution lesson and 3) study student’s attitudes toward science after using the virtual laboratory learning in acid-base solution lesson. The sample of this research was 29 students in mathayomsuksa 1 of Srinakharinwirot university prasarnmit demonstration school secondary which was chosen by using a cluster sampling. The instruments used in this research were 1) The virtual laboratory learning package consists of a teaching plan, worksheets, and virtual laboratory in an acid-base solution lesson. 2) A learning assessment form of acid-base solution learning. 3) A learning achievement test in the scientific process method and 4) A student’s attitude toward science questionnaires. For the statistical analysis in this experimental research, we used a t-test for dependent and One Group Pretest – Posttest research Design. The results revealed that the efficiency of the virtual laboratory learning was 83.17/81.33 and the students gained higher scores in learning achievement, Integrated Science Process Skills, and attitude toward science after learned by using the virtual laboratory learning in acid-base solution.
