Teacher education is the very first step for preparing quality teachers and it is crucial to provide quality teacher training. This research aims to analyze and compare pre-service teacher education policies and programs in Myanmar, the Philippines, and Japan, focusing on secondary science teachers. A case study research design was employed by utilizing Technological Pedagogical and Content Knowledge (TPACK) framework. The result shows that TPACK components found in national education policies and programs in Myanmar were Content Knowledge (CK), Pedagogical Knowledge (PK), and Pedagogical Content Knowledge (PCK). On the other hand, TPACK found in the Philippines and Japan were CK, PK, Technological Knowledge (TK), PCK, Technological Content Knowledge (TCK), and Technological Pedagogical Knowledge (TPK). In all three countries, limited provision of Technological Pedagogical and Content Knowledge (TPACK) was found. It is interpreted that provision of a balanced and sufficient knowledge of TPACK is essential to well equip pre-service teachers with required knowledge and skills considering internationalization and transnational education. This research uncovered the general patterns and trends in pre-service teacher education for science in three Asian countries as well as their uniqueness and best practices.

Home-based biology experiments (HBEs) are practical learning activities that allow students to perform safe and relevant experiments at home. Motivated by the need to innovate teaching approaches in science education due to the COVID-19 pandemic, this study was conducted to determine the effects of home-based biology experiments (HBEs) on their knowledge gains, self-efficacy, and perceived level of engagement. In addition, students' teachers' and parents' feedback were also investigated. This study employed a quasi-experimental research design using a mixed-method approach involving a pretest/post-test design in which ten teacher-collaborators and 836 pupils participated. Fifteen-item teacher-made parallel tests and the 38-item perceptions, self-efficacy and engagement questionnaire were distributed via Google Forms. Results revealed that most participants strongly agreed that HBEs were lesson congruent and risk-free, the materials were readily available, and it was fun and challenging (M=3.56, SD=0.77). Moreover, HBEs were found to be effective in improving pupils' knowledge gains (T=119, z=-4.56, p=0.04), self-efficacy (M=3.36, SD=0.71), and perceived level of engagement (M=3.45, SD=0.69). Responses were significantly different when grouped according to grade level, gender, and type of HBEs used. The results of thematic analysis were categorised as "Affordances" and "Constraints". Six subthemes emerged from the Affordances : "Safety", "Feasibility", "Independent Learning", "Learning Material", and "Affordability", while there were four subthemes for "Constraints": "Expenses", "Student Interaction", "Availability", and "Time Management". It can be concluded that home-based biology experiments are effective and relevant teaching strategies to deliver practical learning in the distance learning modality.
