The nature of science learning includes science as a product, process and attitude. Science learning creates students to have cognitive, psychomotor, and affective abilities. One of the skills that can facilitate is science process skills (KPS). With good science process skills, students' cognitive learning result are also good. However, conditions in the field found that KPS has not been fully taught, cognitive learning result are unsatisfactory and student motivation is low because the class is teacher-centered, one-way so that the class becomes passive. From these conditions, the right learning tool is needed, namely E-LKPD based on guided inquiry. E-LKPD based on guided inquiry contains activities that invite students to process science properly and purposefully. This study aims to determine the application of E-LKPD based on guided inquiry on science process skills, cognitive learning result, and student learning motivation on excretory system material. This research was designed as a quantitative research with One Shot Case Study design. In this study, the sample used was class XI A1 with a total sample of 32 students based on purposive sampling technique. Science process skills are measured in learning activities and practicum. The indicators used are observing, interpreting, classifying, predicting, formulating problems, formulating hypotheses, using materials, writing and analyzing data, compiling discussions, drawing conclusions, communicating, and applying concepts. The results showed an increase in KPS by 17% after treatment and 97% of students completed the KKM with the indicators used, namely C4, C5, and C6. Learning motivation indicators used are attention, relevance, confidence, and satisfaction. Students' learning motivation is in the good category and the questionnaire results show 100% of students are motivated. From the data above, the E-LKPD based on guided inquiry is effective to be applied to science process skills, cognitive learning result, and student learning motivation on excretory system material
One of the factors causing the current low scientific literacy is the limited learning media that has not been able to bridge scientific concepts with empirical reality. The coverage of scientific literacy indicator content in existing media tends to be unbalanced because it only emphesizes theoretical aspects without real-life context. This study aims to develop a ARDis media based on the research "Hyperlipidemia" on the digestive system material that is practical to improve students' scientific literacy. This study uses the Research and Development method with the Alessi & Trollip model which includes the planning, design, and development stages. The research subjects consisted of Biology teacher and students of SMAN 13 Semarang. Data collection instruments included questionnaires and tests. The practicality of the product was assessed through pre-tests and post-tests. The results showed that the ARDis media has very practicality based on the results of assessments by teacher with a score of 98% and students 87,14%. The effectiveness of the ARDis media is demonstrated through students' classical completeness with a score of 94,4% and the results of the N-gain test of 0,66 (moderate category). Thus, it can be concluded that the ARDis media based on the research "Hyperlipidemia" is practical and effective to use as a learning media to improve students' scientific literacy in biology learning, especially in the digestive system material.
This study aims to analyze the characteristics, validity, feasibility, and effectiveness of the E-Atlas of the human skeletal system as a support for practical activities to improve student understanding. The design of this study uses Research and Development (R&D) with the ADDIE method. The subjects of this study were students of class XI SMA N 1 Belik, with 15 students in the small-scale trial and 35 students in the large-scale trial. The data collection method was a questionnaire and a test consisting of 25 multiple-choice questions. The results of the study showed that the developed E-Atlas has the characteristics of facilitating teachers and students with 3D video facilities. The average validity of material experts and media experts was 94.95% in the very valid category, feasibility with indicators of practicality and readability and responses from teachers and students was 87% in the very feasible category, and an increase in understanding of learning outcomes by 0.92 in the high category. This study can conclude that the E-Atlas of the human skeletal system has characteristics according to the design, valid, feasible, and effective to be used as a support for practical activities.
Learning resources for plant growth and development material in Phase F of the Merdeka Curriculum in Indonesia need to be developed with contextual and meaningful content in accordance with biology learning outcomes and support sustainable lifestyles. This research aims to 1) prove validity, 2) analyze practicality, 3) analyze readability, and 4) analyze characteristics of e-booklet from research results with innovations to make and apply biosilica fertilizer. This research is a research and development project. The results of e-booklet development obtained a very valid category based on the assessment results from the validators of content expert and learning media expert. The e-booklet obtained a very practical category based on the results of teacher and student responses. The readability level of the e-booklet was high based on the results of the cloze procedure test. In addition to the innovation of making and applying biosilica fertilizer from rice husk, this learning resource invites students to think creatively to find solutions to environmental problems around them. This e-booklet has some innovations, such as being interactive and equipped with materials in various forms, for instance, text, image, audio, and practicum video. In addition, the e-booklet is integrated with evaluation activities.
The purpose of this study was to develop practical instructions based on a scientific approach to the material of the blood circulation system that were feasible and effective to improve students' science process skills. The research design used was development research or R&D (Research and Development) using the 4D (Four-D) model stages, including: Define, Design, Development, and Dissemination. This study did not reach Dissemination. These practical instructions were developed through feasibility and effectiveness tests. Data collection tools include questionnaire instruments and observation sheets. The questionnaire instrument was made using a Likert scale which is used to measure the feasibility of practical instructions in learning. The observation sheet used is to create indicators of science process skills to measure students' science process skills. Based on the results of the study, the practical instructions were declared very feasible with a percentage value of 98.33% by media experts and by material experts getting a percentage value of 92.18%. In the effectiveness test, it was declared effective in improving science process skills with a percentage gain at the 1 st meeting of 58,14% with medium criteria increasing to the 4 st meeting of 97,04% with high criteria. Based on the results of data analysis in this study, it was concluded that the product of practical instructions based on a scientific approach was very feasible and effective in improving students' science process skills in the blood circulation system material.
