The 21st-century science and technology rapid development requires suitable educational tools to meet the expected learning outcomes desired. This study aimed at producing a mobile learning student worksheet based on Socio-Scientific-Issues (SSI) which is feasible to use in biology teaching activity as well as finding out its effectiveness in enhancing students' scientific literacy skills. This study research and development (R&D) used the ADDIE model. The effectiveness test of mobile learning student worksheet in enhancing students’ scientific literacy skills was done by using a one-group pretest-posttest design. The research findings indicated that the developed mobile learning student worksheet based on SSI is feasible to use in biology teaching activity and become the considerable tool in enhancing students’ scientific literacy skills based on the n-gain score of 0.75 (high category). Thus, it is suggested for science teachers, particularly biology teachers, to adopt this tool to support the learning activity they conduct.

The aim of this study to determine the interest in studying biology and the effect of interest in studying biology on the learning outcomes of cognitive biology during the Covid-19 pandemic. Based on several previous studies, it is known that online learning during the Covid-19 pandemic greatly influenced students' interest in learning biology. However, it is not yet known the level of interest in learning itself due to the effect of online learning, and it is not yet known the magnitude of the influence of interest in learning biology during online learning during the Covid-19 pandemic. This research was conducted in 2nd-grade science in Senior High School No. 13 Semarang using a survey method with correlational analysis. The data collection techniques in this study were questionnaires and documentation which were analyzed by testing the hypothesis using the correlation test and regression test. The results showed that the percentage of students' interest in learning biology online during the Covid-19 pandemic was 68.16%. The results of the correlation test show that there is a relationship between interest in learning biology with the cognitive biology learning outcomes of students. The results of the regression test and the value of R squared indicated that students' interest in learning biology affects learning outcomes of cognitive biology. The percentage of the influence of students' interest in learning biology on the cognitive biology learning outcomes is 34%. The interest in learning biology of students when learning biology online during the Covid-19 pandemic is still low. The interest in learning biology when learning biology online during the Covid-19 pandemic effect the cognitive biology learning outcomes of students

The school reform models which is most important today is the schoolbased management model (SBM). The Indonesian government issued guidelines regarding the implementation of SBM in 2002. Schools that have implemented SBM are expected to increase the learning quality. This research is a quantitative research. An approach of research which reveals particular situations of social by properly reflecting reality, which is formed by words based on techniques for collecting and analyzing relevant data gathered from situations which is natural is called qualitative research. This study aims to provide an empirical picture of the quality of learning based on RPP instruments and learning implementation instruments by teachers. The researcher chose a junior high school in Konawe Regency, Southeast Sulawesi, Indonesia. The results show that there are several components that have not been implemented optimally, namely: the implementation of effective learning strategies / strategies, the use of learning resources / media in learning, the design of evaluation tools and monitoring tools to monitor the progress and learning outcomes of students in certain achievements. competencies, and make use of feedback for learners.
