Evo & Lusi: A Novel to Increase Motivation to Learn Evolution
Get PDFThis study aims to determine the feasibility of evolution learning novels as an alternative learning resource in high school biology learning and to determine the effectiveness of evolution learning novels in increasing learning motivation in students. The research method used is Research and Development (R&D). The type of research and development used is the ADDIE model (Analyze, Design, Develop, Implement and Evaluate). The implementation stage is carried out with a pre-experimental design type one-group pretest and post design. The validation results that have been carried out, the product developed has an average validation percentage of 82.5%, which is very valid. The percentage of validation is obtained from the validation results by learning novel development experts and evolutionary material experts, but with various revisions that need to be made, the majority of which lie in writing errors and laying the concept of evolution. The products produced increased student learning motivation when tested on a limited basis at SMA N 1 Bandar Batang Regency. The initial motivation level of SMA N 1 Bandar Batang Regency students is included in the excellent category with a percentage of 59.17%. After being given a novel to read, the student motivation level increase to 79.86% or in high criteria. The results obtained, the product produced as an evolution learning novel is included in the category of feasible and quite effective DOI: http://dx.doi.org/10.23960/jbt.v11.i1.2699

Teachers’ Beliefs and Efficacy of Technological Pedagogical Content Knowledge for STEM Learning
Get PDFThe application of STEM in Indonesian education has grown. The TPACK framework could enhance teachers' beliefs and efficacy in STEM education. However, there need to be more details evidence of the teacher's beliefs and efficacy when facing or dealing with STEM-based learning. Therefore, exploring the teachers' views and perspectives on implementing TPACK in conducting STEM learning is crucial. This study aimed to reveal teachers' beliefs and efficacy on their TPACK in designing STEM learning. The case study method was used with 9 participants enrolled in a STEM learning program for science teachers. Teachers' self-assessment questionnaires and online interviews collected teachers' TPACK beliefs and efficacy. We analyzed quantitative data from self-assessment questionnaires using interval class analysis. We used a descriptive approach to analyze data from interviews. The results show that teachers regard themselves as highly competent in implementing their TPACK on STEM learning. Out of the three TPACK domains, teachers showed better efficacy in the integrative STEM domain. Of the three TPACK domains, teachers showed better efficacy in the integrative STEM domain than in technology-related knowledge. They are, nevertheless, generally enthusiastic about improving their technological skills. These findings reflect the urgent need to provide professional teachers programs to support this positive belief and efficacy on teachers' TPACK for STEM learning.

The model is the media image. The subjects of this classroom action research were class XII.MIPA 8 students of SMAN 1 Tasikmalaya. The number of students is 35 people, 14 boys and 21 girls. This classroom behavior study was conducted in the 2022-2023 school year. This classroom action research was conducted for three months in odd semesters starting from October to December 2022. The research methodology for this classroom action research was carried out in two cycles, each cycle consisting of two meetings. Each cycle consists of planning, implementing, observing and reflecting. The research process consisted of Preliminary Research, Cycle 1 Planning, Cycle 1 Action Implementation, Cycle 1 Observation, Cycle 1 Reflection, Cycle 2 Planning, Cycle 2 Action Implementation, Cycle 2 Observation, and Cycle 2 Consists of reflection. The data collection technique is to collect test scores using tests (written tests) given at the end of each lesson in each cycle. Observational data is made by observing student activities during the learning process. Data analysis was performed using percentage statistics. The results showed that the students' learning outcomes increased from 40 before learning to 70 in cycle 1 and 85 in cycle 2. Student learning activities increased from the category of 'Enough' to 'Good' and from 'Good' to 'Very Good'. The application of media images can increase the activity and learning outcomes of biology in the genetic material for class XII.MIPA 8 SMAN 1 Tasikmalaya Academic Year 2022/2023.

Metacognitive Awareness Based on Gender in Conceptual Change Learning Assisted Android Mobile-learning on the Topic of the Human Reproductive System
Get PDFAbstract: Metacognitive Awareness Based on Gender in Conceptual Change Learning Assisted Android Mobile-learning on the Topic of the Human Reproductive System. This study aims to describe the level of metacognitive awareness of male and female students in conceptual change learning on the topic of the human reproductive system, the relationship between knowledge about cognition and cognitive regulation. The research subjects were students of class XI at a high school in Bandar Lampung. The instrument used to collect data is a metacognitive awareness questionnaire developed by Schraw & Dennison (1996). The results of the study show that male and female students are dominantly at the level of "developing" metacognitive awareness in the sense that they can be helped towards awareness of thinking for themselves if they are inspired or supported. This study also revealed that girls are more dominant in their minds-on, while male students tend to be more hands-on. Each knowledge about cognition and regulation of cognition has a strong relationship, both in male and female students. Through this research, it appears that conceptual change learning facilitates male and female students to identify and revise concepts that develop in society related to the human reproductive system to become scientifically correct.

Profil Durasi Screen Time dan Tingkat Stres Paska Pembelajaran Online pada Calon Guru Biologi
Get PDFThe implementation of online learning methods requires students to be in front of a screen for a longer time. This light exposure is thought to be related to emerging problems such as academic stress. Therefore, researchers want to know the profile of student stress levels during the distance learning period during the COVID-19 pandemic. This study used observational research methods with a cross-sectional research design. The research subjects were students of the Biology Education UMMI with 58 respondents. Stress level data was obtained through the DASS-42 questionnaire. The results showed that 39.65% of students were active in front of gadget screens for learning activities for 8 to 10 hours per day, and 48.28% of students used gadgets before going to bed. In addition, based on the DASS-42 questionnaire, it shows that students in general are at a moderate level of stress (41.38%), a very severe level of anxiety (36.21%), and a normal level of depression (56.90%).Penerapan metode pembelajaran daring mengharuskan mahasiswa berada di depan layar dalam waktu yang lebih lama.
