Abstract: The ultimate goal of the authors is to examine the effectiveness of virtual labs as an instructional tool; and initial purpose here is to glean student perceptions of the tool from an evaluative perspective. In this way the purpose of this study was to investigate the effect of Virtual Lab Experimentation (VLE) on students’ conceptual understanding of photo electric effect. To achieve this, a pre–post comparison study design was used that involved 50 undergraduate students. Two groups were set up for this study. Participants in the control group used RLE to learn photo electric effect, whereas, participants in the experimental group used VLE. Achievement test was given to the groups before and after the application as pre-test and post test. The independent samples t- test, were used for testing the data obtained from the study. According to the results of analyzes, the experimental group was found more successful than the control group. It is hoped that findings from this study will provide useful information for instructional improvement as well as adding to the literature in this area.
