STEM integrated electronic student worksheet to promote conceptual understanding and literacy skills of students

The development of the Industrial Revolution 4.0 era requires students to have good literacy skills. The preliminary investigations at Senior High School 9 Padang showed that students' literacy skills were still relatively low. This study investigated the effect of STEM integrated electronic student worksheet (STEM integrated ESW) to promote students' conceptual understanding and literacy skills. We employed quasi-experimental research with a post-test-only design. A sample consist of 71 students was taken using the cluster random sampling technique. The post-test items and the literacy performance assessment sheet were used as data collection instruments. Data were analyzed using a comparison test of the two means of independent groups. The research revealed that the test on the conceptual understanding aspect obtained a t-test of 5.817. Aspects of data literacy skills obtained z test -6.085. In the aspect of technological literacy skills, the t-test value was obtained at 8.596. The analysis of students' conceptual understanding and literacy skills showed that the experimental class average was superior to the control class. Thus, STEM integrated ESW has given significantly effects on students' conceptual understanding and literacy skills. It is hoped that further researchers can develop similar products with different topics to optimize students' literacy skills.
