Abstract

Laboratory course activities often focus on "cookbook style," so their activities have not yet integrated with scientific thinking as an essential aspect. In this research, the laboratory experience of microbial analysis techniques was redesigned using alternative inquiry to involve students in isolating and characterising yeast to make the bread rise. This research aimed to determine the effect of implementing inquiry-based laboratory experiences on improving students' technical skills and the structure and characteristics of laboratory courses. The method used a single case study to obtain a complete picture regarding implementing laboratory course redesign. Laboratory experience activities consisted of pre-laboratory (reinforcement of theory) and investigation (preparation of methods, laboratory investigation activities, data analysis and presentation, and writing written reports). Overall, our results suggest that inquiry-based laboratory experiences can improve students' microbial analysis technique skills in strong collaboration. In addition, students considered several benefits from this learning, such as developing designs and conducting laboratory investigations close to the original context. With these results, educators can use the redesign of this laboratory course without applying full "course-based undergraduate research experiences" to students.

Abstract

The biology material on the excretory system has a high level of learning difficulty, including the complexity of the material and the high level of abstraction, which can affect students' learning process and outcomes. Therefore, it is necessary to analyze the internal and external sources causing learning difficulties by conducting research that aims to interpret: 1) the level of students' learning difficulties based on the cognitive level of the excretory system material, 2) the factors causing students' learning difficulties based on the cognitive level of the excretory system material. This research is a qualitative study using an ex post facto method conducted at SMA Negeri 2 Konawe Selatan. The subjects of this research are 56 Grade XI students who experience learning difficulties, and the biology teacher. The data collection techniques used are: 1) tests, which were analyzed descriptively statistically; 2) interviews, which were analyzed through four stages: collection, reduction, display, and conclusion, followed by testing the validity of the data through triangulation. The results of this research show that: 1) Students' learning difficulties viewed from the cognitive levels of each learning indicator on the excretory system material are generally categorized as slightly difficult with a percentage of 58.93%; 2) The factors causing students' learning difficulties are students' interest in learning, students' habits during the learning process, evaluation techniques, as well as family, school, and community environmental aspects.
