Abstract:
The objective of this research was to 1) study users background, experience and needs to develop a virtual science laboratory using mobile application in blended learning 2) develop a virtual science laboratory using mobile application in blended learning to enhance secondary school students science process skills, and 3) examine the effect of using a virtual science laboratory using mobile application in blended learning. The research divided into three phases according to the research objectives: 1) studying the needs for virtual science laboratory using mobile application in blended learning from 438 secondary school students and 447 secondary school science teachers, 2) developing a virtual science laboratory using mobile application in blended learning to enhance studentsscience process skills, in which six experts conducted an evaluation and later testing the virtual science laboratory prototype with the sample group of 20 secondary school students, 3) studying the results of using a virtual science laboratory using mobile application in blended learning to enhance students science process skills of 30 mathayom suksa one students of Wat Intharam School. The data were analyzed by using frequency, percent, mean, standard deviation, and tested the hypothesis with t-test dependent. The research result indicated that 1) most students and teachers used mobile phones runing on the Android operating system, 2) the primary needs of students to have a virtual science laboratory using mobile application was to be able to predict future outcome (PNIModified = 3.14) and the primary factor affecting the use of mobile virtual science laboratory applications was beautiful and attrative design (x̄ = 4.91, S.D. = 0.38), meanwhile the primary needs of was to help students to be able to predict future outcome (PNIModified = 3.09) and the primary factor was to support students to do science experiment themsleves (x̄ = 4.83, S.D. = 0.51), 3) the result form the experimental group revealed the post-test score of the science process skills was higher than pre-test at the .05 level of sinificance, and 4) the learners were satisfied with the mobile virtual science laboratory at the most satisfactory level.
