Interest affects learning; it also affects students' attitude towards science and career choices. It is therefore urgent to increase students' interest and improve their attitude towards science to face the complex challenges of the future. This study transformed cutting-edge induced pluripotent stem cells (iPSC) research into an informal science course to explore the effect of students' situational interest (SI), concept understanding and attitude towards science. A total of 52 tenth-grade students of upper secondary school participated in an informal science course including a one-day workshop and exploration in a science museum, and one-day of lab work in a university laboratory. The questionnaire data were analysed by pre- and post-t test to explore the learning outcomes, and the learning experience reports were content analysed to explore the influencing factors. Results showed that 1) students' SI was significantly enhanced, with the trigger and affective components of SI scoring, but not the value component; 2) Students' iPSC concept understanding was significantly enhanced; 3) The course enhanced students' SI, iPSC concept understanding and attitude towards science via different influencing factors; 4) The value factors may influence students' positive attitude towards science and engagement in science. We also present some suggestions for informal science course design and teaching practice. [ABSTRACT FROM AUTHOR]

Marinyo is a culture left by the Portuguese around the 15th century in Maluku. The purpose of this study was to find out to what extent students' misconceptions about the concept of sound in the Marinyo case in the Kepuluan Tanimbar Regency. The method used was a qualitative study in ethnography in ten villages in two sub-districts. In addition, they conducted a survey in the form of a diagnostic test in the form of questions related to the Marinyo case on 300 elementary school students. The findings in the field show that students experience relatively high misconceptions. It was because teachers did not accustom students to learn from natural phenomena around them and were given scientific questions to seek, find and provide answers and solutions related to these natural phenomena. The teacher was more pursuing the conditions and problems of physics in textbooks and less exploring contextual matters. Future researchers are suggested to develop physics or science teaching materials based on regional local advantages that are oriented towards understanding concepts, mental models, critical thinking, problem-solving, creativity and innovative thinking so that teachers and students can learn well so that knowledge of science becomes better.

Collaborative-metacognitive use of science literature teaching approach (CMSLTA) refers to a researcher-made teaching approach from the Philippines that comprises four components, namely (a) formation of groups with three to four members who have varied reading comprehension ability and assigned rotating roles; (b) use of Scientific Method Learning Plan; (c) reading a science literature including a comic strip, song, parable, poem, infographic, and short story; and (d) answering collaborative-metacognitive prompts in the learning journal. There are separate research studies on the use of science literature and collaborative metacognition in instruction. However, there is a dearth of studies combining the two teaching approaches. In this light, this research examined the effects of CMSLTA on grade 2 students' concept understanding of plants and animals. A two-group pretest–posttest quasi-experimental design was employed on 74 grade 2 students aged six to eight. One group was exposed to CMSLTA while the other group was exposed to the conventional teaching approach (CTA). Findings revealed that CMSLTA significantly improved students' concept understanding. Remarkably, this research aids educators in providing students with early exposure to science and understanding science concepts through the combined use of science literature and collaborative metacognition as a teaching approach.
