Histology practicum, as one of the compulsory practicum courses, offers a great opportunity to practice various aspects of science process skills through microscopic tissue observation activities, identification of cell and tissue structures, and analysis of tissue functions in organisms. This study aims to analyze the science process skills biology education students through histology practicum activities. This study uses a quantitative descriptive approach with a survey method to analyze the science process skills of biology education students through histology practicum activities. Data collection in this study used three main techniques, namely science process skills tests, direct observation, and analysis of practicum report documents. Furthermore, the data were analyzed descriptively quantitatively using descriptive statistics to describe the profile of students' science process skills. Analysis per aspect revealed that students had good skills in the aspects of observing (78.50%), classifying (76.33%), interpreting data (71.67%), applying concepts (73.25%), and communicating results (73.40%), which indicates that histology practicum is effective in developing basic science process skills. However, the aspects of formulating hypotheses (58.17%) and planning experiments (54.83%) were still in the sufficient category, indicating that students experienced difficulties in integrated science process skills that require higher-order thinking skills. The findings this study provide important implications for the development of more comprehensive histology practicum learning strategies, including the integration of inquiry approaches, the use of continuous formative assessment, the application of differentiated learning, and strengthening the connection between theory and practice to optimize the development of all aspects of science process skills of prospective biology teachers.  

The implementation of Biology learning in senior high schools still faces various challenges, particularly the limitations of laboratory facilities and the low level of students’ science process skills(KPS). KPS  is an essential ability that supports conceptual understanding and critical thinking development through practical activities. This community service program aimed to improve students’ basic laboratory skills and KPS through hands-on training. The program was conducted at the Biology Education Laboratory of the Faculty of Teacher Training and Education, Kuningan University, involving students from SMAN 1 Ciwaru. The methods included socialization, laboratory equipment training, preparation of practical materials, animal dissection training, application of virtual laboratory technology, and mentoring and evaluation sessions. The results showed a significant improvement in students’ abilities to use laboratory tools, prepare materials, and perform experiments according to scientific procedures. Before the training, only 32% of students were able to use laboratory equipment correctly, while after the training, this increased to 84%. The average scores for observation, measurement, data interpretation, and scientific communication also improved significantly. Furthermore, a satisfaction survey revealed an average score of 4.6 out of 5, with 92% of participants stating that the activity was very beneficial. This program proved effective in enhancing students’ basic laboratory and science process skills, providing meaningful, applicable, and sustainable science learning experiences.

Science process skills and conceptual mastery are two crucial aspects. Conceptual mastery involves understanding scientific concepts, while science process skills encompass the ability to conduct scientific work, apply concepts, predict and inquire, interpret and communicate, hypothesize, conclude, plan, and conduct experiments. The aim of this study is to determine the relationship between science process skills and conceptual mastery through practical methods. The research method employed is quantitative with a correlational design. The study population includes all 11th-grade MIPA students at SMA Negeri 1 Bumi Agung, Lampung, with cluster random sampling used to select Class XI MIPA 1 as the sample. Data collection involved observation sheets and tests. Data analysis was conducted using Pearson product-moment correlation coefficient. The correlation analysis began with testing prerequisites such as normality and linearity, confirming that the data were normally distributed and linear. The correlation between science process skills and conceptual mastery yielded an pearson correlation coefficient (r) of 0.940 with N = 32. The critical value (r-table) was 0.349. Since 0.940 > 0.349 and the significance value (2-tailed) was 0.00 < 0.05, H0 was rejected and H1 was accepted, indicating a very strong relationship between science process skills and conceptual mastery through practical methods. Theoretically, these findings affirm the importance of practice-based learning in strengthening conceptual understanding. Practically, the results recommend integrating structured laboratory activities to enhance students’ scientific inquiry skills and conceptual mastery.

This study aims to examine in depth the effectiveness of the application of the Children Learning in Science (CLIS) learning model in the Natural Science (Science) learning process. The background of this study stems from the problem of low active student participation in class, which is largely caused by difficulties in understanding abstract science concepts. The CLIS model offers a learning approach that emphasizes active student involvement through a series of systematic learning stages. The method used is a literature review with a qualitative descriptive approach. Analysis was conducted on 25 articles from national and international publications. Each article was reviewed based on relevance, research methods, main findings, and the suitability of CLIS application in various science learning contexts. The results of the study indicate that CLIS has proven effective in improving students' understanding of science concepts, developing science process skills such as observation, classification, measurement, and hypothesis testing, and encouraging active student participation during the learning process. In addition, this model is also able to improve critical thinking skills through exploration activities, experiments, group discussions, and reflection on learning outcomes. The CLIS stages, which include exploring students' prior knowledge, introducing new concepts through experiments, strengthening understanding through discussions, and strengthening concepts through reflection, enable students to construct knowledge independently and meaningfully. Based on these findings, CLIS is considered relevant and can be an effective alternative learning model to improve the quality of science learning at various levels of education.

This study aims to examine the problem of the lack of implementation of experiment-based learning in Biology subjects at SMA Nahdlatul Ulama Padangsidimpuan. The method used is descriptive qualitative with a case study approach, with data collection through interviews with Biology teachers and literature studies. The results showed that limited laboratory facilities, lack of practicum tools and materials, and limited learning time allocation were the main obstacles in the implementation of practicum. Although teachers realize the importance of experimental activities in improving students' understanding and science process skills, structural support from schools is still very limited. In response to these obstacles, several alternatives such as the utilization of virtual laboratories, the use of experimental videos, and simple experiments based on local resources have been attempted. This research recommends strengthening educational policies that support practicum-based learning through the provision of adequate infrastructure, continuous training for teachers, and development of alternative learning media. Thus, Biology learning can be more effective in fostering students' scientific skills and critical thinking according to the demands of the 21st century.

This research aims to analyze and develop students' science process skills, particularly in the use of measuring instruments, and their influence on understanding the concepts of quantities and units in physics. This research is motivated by the importance of mastering skills in using measuring instruments in physics learning, as well as the need for innovative teaching materials to improve students' understanding of fundamental concepts. This study employs a mixed-methods approach, combining both quantitative and qualitative methods. The quantitative approach is used to analyze data on students' skills in using measuring instruments and their understanding of concepts through tests. Meanwhile, the qualitative approach is employed to analyze data from observations and interviews with students and teachers regarding the effectiveness of using guided inquiry-based interactive multimedia teaching materials. The interactive multimedia teaching materials developed in this research are designed to facilitate learning about measuring instruments and measurement using a guided inquiry approach. A behavioristic approach is also considered in the development of these teaching materials to ensure students receive appropriate reinforcement throughout the learning process. Through this research, it is hoped that effective ways to develop students' science process skills and enhance their understanding of measuring instruments and measurement concepts in physics will be discovered, ultimately improving physics learning outcomes as a whole.
