Science learning integrated with web-based formative assessments to improve students’ understanding of concept

Assessment should not only be carried out when the learning ends (or assessment of learning) but also during the learning process through assessment for learning and assessment as learning approaches. These approaches can be achieved by integrating formative assessment during the learning process. Formative assessments provide information about students’ strengths and weaknesses in learning by giving feedback. Giving immediate feedback is very necessary to close the gap in students’ concepts. Giving a test with immediate feedback can increase students’ learning interests and provide reinforcement and improvement in students' understanding of concepts. This research aimed to find out the increased junior high school students' concepts understanding in science learning which is integrated with web-assisted formative assessment on materials of vibrations, waves, and sounds. This research was conducted in VIII-C Class SMPN 1 Malang, the academic year of 2018-2019. The research design used was a mixed method with an embedded experimental mixed method. Quantitative data were in the form of pretest and posttest scores. Qualitative data were the results of observations during the learning process, answers to worksheets, and the results of interviews with students. On the other hand, quantitative data analysis includes the Kolmogorov Smirnov test, paired t-test, N-gain, and d-effect size. Qualitative data analysis is data reduction. From the d-effect size test result, the score obtained was 2.25 (high category), and N-gain indicated a score of 0.63 (above the medium category). The study indicated that students' understanding of concepts has improved through science learning integrated with web-assisted formative assessment.
