Development of RQANI Learning Modules to Improve Students' Understanding of concepts Class XI Science at SMA Negeri 6 Ternate City

RQANI (Reading, Questioning, Answering, Elaboration, and Integration) is a learning model that integrates science and Islamic values. Utilizing modules in the learning process can provide learning opportunities for students to be more independent and motivated to master concepts. The research objectives were to identify (1) the validity of the RQANI module on body defense system material for class XI IPA students at SMA Negeri 6 Ternate City and (2) the effectiveness of the RQANI learning module in increasing students' understanding of concepts in class XI Science at SMA Negeri 6 Ternate City. This research is development research that refers to 4-D development design. The trial was carried out on a limited scale on class XI Science students at SMA Negeri 6 Ternate City. The instruments used in collecting research data consisted of validation sheets for research modules and instruments, response questionnaires, and essay tests to measure understanding of concepts. The research results showed (1) the validity of the RQANI-based learning module on body defense system material by the first validator in the very valid category (90.41) and the second validator in the valid category (79.16); (2) RQANI-based learning modules are effective in increasing concept understanding with 38.46% of students obtaining N-Gain at high criteria; and 38.46% of students gave very good responses and 53.84% of students gave good responses to the RQANI module. The research conclusion is that the learning module is declared valid and effective in increasing student understanding. DOI: http://dx.doi.org/10.23960/jbt.v11.i2.28919

Implementation of the POGIL Model Combined with a Digital Mind Map Based on Online Learning to Improve Creative Thinking Skills and Student Cognitive Learning Outcomes at SMAN 2 Malang

Education in 21st Century has supported use of the 2013 Curriculum which demands skills, one of which is creative thinking skills. This skill demand is inversely proportional to the real conditions in class XI MIPA 3 SMAN 2 Malang. Initially, creative thinking skills showed an average of 50.20%, indicated that student still had difficulty writing many different answers and were not equipped with details, used the language of books and the internet, did not see problems from various directions. Low cognitive learning outcomes are proven by the 2020/2021 odd semester exam scores with 41.39% of students getting scores below the KKM. Teachers have difficulty implementing learning models during the Covid-19 pandemic. The research aims to improve creative thinking skills and cognitive learning outcomes using the POGIL model combined with a digital mind map based on online learning. The research aims to improve students’ creative thinking skills and cognitive learning outcomes using POGIL model combined digital mind map based on online learning. The method uses Classroom Action Research with Kemmis Mc Taggart design. Collecting data through creative thinking questions from UKBM, digital mind map, and pretest-posttest. The results of the cycle I and cycle II showed an increase in creative thinking skills from 78.37 to 86.26 (UKBM) and 83.74 to 91.50 (digital mind map), the average class cognitive learning outcomes from 78.90 to 80.29, and classical cognitive completeness by 80.65% to 87.10%. The increase was due to the integration of guided inquiry, cooperative, and digital mind map that we're able to create an active atmosphere, creative thinking, teamwork, and concept formation. DOI: http://dx.doi.org/10.23960/jbt.v11.i2.2882

Promoting College Student’s Twenty-First Century Skills through a STEM Learning Project

There is a need to prepare college students with non-cognitive or 21st Century skills to prepare them for successful college and future careers. As the number of applied STEM in Indonesian education increases, research is needed to understand how STEM learning projects promote student 21st Century skills. This study used a case study and mixed-methods conversion design to convert qualitative data into quantitative data by applying pre-established rubrics. This study provides evidence that STEM learning projects are beneficial to promote students' 21st Century skills, which are: (a) knowledge construction, (b) real-world problem solving, (c) skilled communication, (d) collaboration, and (e) self-regulation. The result shows that students demonstrate the highest grade on collaboration and the lowest on knowledge construction. Although most of the student work introduced multiple 21st Century skills and the overall scores were satisfactory, student knowledge construction still needs improvement. DOI: http://dx.doi.org/10.23960/jbt.v11.i1.2704

The purpose of this study was to improve biology learning outcomes in genetic material for class XII-MIPA 8 students of SMAN 1 Tasikmalaya in the 2022/2023 academic year. 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'.

Implementation of the Project Based Learning (PJBL) to Increase Students Learning Interest and Learning Outcomes in Biotechnology Concept

The success of learning can be influenced by various factors including students learning interests. However, there are still many students who have a low interest in learning, and the interest in learning that is owned by students can affect the learning outcomes of students during the learning process. This study aims to determine the increase in learning interest and student learning outcomes in biotechnology material. The research method used is the class action research method (CAR). The subjects in this study were all students in class IX B of junior high school 1 Baregbeg totalling 35 people with details on 17 boys and 18 girls. The data analysis technique used in quantitative descriptive research allowed the data obtained from the results of the research to be processed with the help of Microsoft Excel 2016 to find out the proportions of student interest in learning, the proportion of interest in learning each cycle, and the proportion of completeness of student learning outcomes on the cognitive aspect. Based on the results of the research it shows that the Project Based Learning (PJBL) model can increase student interest in learning and learning outcomes of students in biotechnology concept with an interest in learning in cycle I obtaining a proportion of 67% and in cycle II of 77%. Then the learning outcomes of students in cycle I were 49% mastery and in cycle II they increased to 91%. So with the proportion that has increased in cycle II the Project Based Learning (PJBL) model is very effective to be applied in the learning process as an effort to increase interest in learning and student learning outcomes in biotechnology concept in class IX. DOI: http://dx.doi.org/10.23960/jbt.v11.i1.2724
