Lateral Thinking Ability Through Challenge-based Learning with Sparkol Videoscribe.

Online learning during the Covid-19 pandemic was very interesting to observe because learning can be done anytime and anywhere. However, Covid-19 has an impact on the learning process in schools and students' thinking abilities. The purpose of this paper is to analyze the differences in the improvement of mathematical lateral thinking skills between students who received challenge-based learning through sparkol videoscribe and those learning through WhatsApp. The research method used was a quasi-experimental, non-equivalent control group design. The sample was randomly selected from four parallel high school classes in the city of Bandung, namely class X 1 who learned through videoscribe sparkol and class X 3 who studied via WhatsApp. The instrument used is a test of mathematical lateral thinking ability and a test of prior mathematical knowledge. Data analysis was done using two-way ANOVA. Findings: A difference was observed in the achievement of mathematical lateral thinking skills between students who carry out learning through sparkol videoscribe better than those learning through WhatsApp based on prior knowledge of mathematics in the smart, medium, and low categories. Challenge-based learning sparkol videoscribe makes it easier for students to understand the material, the construction process, interaction, and reflection, thereby increasing the ability to think mathematically, laterally.
