School laboratories are vital for building students' understanding and scientific skills through hands-on activities. However, the laboratory at SMAN 1 Rasau Jaya in Kubu Raya Regency is underutilized, potentially reducing students' motivation and skills. This study aims to evaluate the basic laboratory knowledge and skills of students at SMAN 1 Rasau Jaya, focusing on measurement, weighing, and dilution. This research utilizes a descriptive quantitative survey method to assess the basic laboratory knowledge and skills of Grade XII science students at SMAN 1 Rasau Jaya, with a purposive sample of 35 students. Data analysis was conducted to describe laboratory knowledge and skills as well as their relationship. The study found students’ laboratory knowledge to be generally moderate, with average scores of 41% for measurement, 45% for weighing, and 43% for dilution skills. Practically, 34.3% of students were rated as good and 8.6% as very good in measurement skills. Weighing skills were stronger, with 68.6% in the very good category, while dilution skills need improvement, with only 31.4% very good and 17.1% moderate. A low but significant correlation (r = 0.376, p = 0.026) suggests that theoretical knowledge hasn't fully translated into practical ability. In conclusion, the study highlights a gap between students' theoretical knowledge and practical skills, suggesting a need for increased hands-on practice to enhance scientific proficiency and motivation among students at SMAN 1 Rasau Jaya.

For some time, student-centred approaches in secondary schools have been advocated for the teaching and learning of mathematics and science in Malawi. It, however, became formal for all subjects after the 2015 curriculum review. Adopting an outcome-based education (OBE) curriculum in secondary education necessitated its implementation through student-centred learning approaches. Since the formalization of the instructional strategy, not much is known about how science teachers effectively implement student-centred teaching in their lessons. This study aims to determine the extent of student-centred teaching implementation in science classrooms as teachers translate theory into practice. Secondary schools were randomly sampled in the Central West Education Division, and the school management identified the teachers to participate in the study. Data was collected through document analysis, lesson observation, and interviews. Seven different science lessons in Biology, Physics, and Chemistry, taught by seven different science teachers, were observed in various schools in Malawi. The study has found that implementing student-centred learning is still challenging due to teachers’ varied conceptualization of the construct, unavailability of adequate resources, and teacher capacity-related issues such as knowledge and skills. This affects attainment levels of the curriculum objectives, consequently challenging the achievement of national goals, as highlighted in Malawi Vision 2063, which is grounded in sustainable development goals in the long term.

The problem that is often experienced in learning chemical bonds topics is that students do not know the benefits of learning chemical bonds in everyday life, one of the causes is because the teaching materials used have not been able to link the material with contextual examples, real problems in everyday life, and the lack of opportunities for students to conduct investigations, making the learning less meaningful. This research aims to produce valid student worksheets based on the Nature of Science (NoS) on chemical bonds topics and determine user response. The research method used is Research and Development (R&D) using the 4-D development model (define, design, develop, and disseminate). The data collection instruments were validation sheets and user response questionnaires for teachers and students. The data analysis method in this research was carried out quantitative and qualitative data description. The results indicated that the developed student worksheets based on the Nature of Science (NoS) were deemed valid, with an average validation score of 96.12% from 3 validators. One-on-one trials were conducted with 3 students with different abilities to gather feedback for improvements. The user response test was conducted to 2 chemistry teachers and 20 students (10 students from SMAN 4 Pekanbaru and 10 students from SMAN 1 Pekanbaru), yielding response percentages of 90.06% from teachers and 90.84% from students, both categorized as very good. So, it can be said that these student worksheets have good potential to be used in learning chemistry, especially on topics related to chemical bonds.
