Abstract:

Arduino is a tool which the data taken from sensors can be used. Temperature and humidity information can be measured by Arduino, robotic applications can be realized with distance sensors, light and colors can be detected, applications can be realized with accelerometer. It is aimed to determine the effects of analytical chemistry experiments supported by Arduino on pre-service teachers’ self-efficacy toward information technologies. Participants of this study are 61 pre-service teachers. There are one experimental group (nEG:34) and the other control group (nCG:31) with random assignment method. In this study, one of the experimental research models "pre-test-post-test control group semi-experimental research model" has been adopted. Participants were pre-tested and post-tested. In the experimental group, closed-ended experiments supported by Arduino were used. In the control group, closed-end experiments not supported Arduino were used. In both groups, confirmatory approach based experiment design was adopted. The measurement tools were selected from the scales available in the literature. In order to measure self-efficacy perceptions of information technologies, "Information Technologies Self-efficacy Perception Scale for Pre-service Teachers (ITSPS)" was used. According to the results of the study, it was determined that the analytical chemistry experiments supported by Arduino has effects on their technology self-efficacy in a positive way. In this study, it was seen that self-efficacy of pre-service teachers towards information technologies developed with closed-end chemistry experiments supported by Arduino. Arduino should be assessed on students' self-efficacy by testing in different chemistry-related trials. In addition, easier application of Arduino should be investigated .
