Abstract

This research aims to describe the enhancement of students' science process skills with the application of guided inquiry model. The design used in the study was pre-experimental design with a research draft of one group pre-test post-test. Research was carried out with the subject of two classes VIII at MTs Hasyim Ash'ari Sukodono, where the first class had 32 students, and the second class had 36 students. This research was conducted in MTs Hasyim Asy'ari Sukodono because there has been no research in the school before, with the different time allocations from other schools, that is 4x35 minutes, where the curriculum determines the allocation of learning time 5x40 minutes and has not been established learning science process skills. Data collection techniques in the form of a question description that corresponds to the science process skills indicator. The result is the submission of science process skills, the percentage of achievement of each aspect of science process skills, n-gain pre-test and post-test, and n-gain every aspect of science process skill. The results showed that there has been an enhancement in every aspect of the science process skills, increasing the achievement percentage of each aspect of science process skills, and increasing the n-gain of each aspect of science process skills in two classes of 0.59 with medium category and 0.64 with medium category. Based on these results, it can be concluded that the guided inquiry model can enhance the students' science process skills, and can be applied to the pressure topic.

Abstract

The learning process in online classes during the pandemic rarely comes to practice, this can be overcome with a Home Laboratory practicum. Knowing the effect of implementing a Home Laboratory on the topic of heat transfer on the science process skills of SMP Negeri 60 Surabaya students during the covid 19 pandemic is the purpose of this research. Quasi experimental was used as the design and subjects of this study were students of class VII-A, VII-B, and VII-C of SMP Negeri 60 Surabaya for the academic year 2020/2021. The sample selection using random sampling technique or random selection of as many as twenty students. The instruments used are test and non-test with quantitative descriptive methods. The tests are in the form of pretest and posttest with multiple choice reasons, while the non-test is Home Laboratory performance assessment and student worksheet assessment. The data collection technique used a written test in the form of reasoned multiple-choice questions, the results were analyzed through percentages and then projected on improving science process skills. The interpretation criteria of the results of the analysis of each aspect of the science process skills of each student experienced an increase from the pretest. The average value of the performance score in each Home Laboratory practicum is said to exceed the KKM, which is 91.6. Overall, the results of the research on the implementation of the Home Laboratory practicum on the topic of heat transfer during the pandemic at SMP Negeri 60 Surabaya is said to be influential in training students' science process skills.

Abstract

The purpose of this study was to determine the application of a scientific approach to science learning during the pandemic at SMP Negeri 58 Surabaya. This type of research is descriptive qualitative. The data used is in the form of learning recordings carried out through web meetings such as Google Meet and Zoom.. The resource persons of this research are science subject teachers. Data collection techniques through observation, interviews, document studies and questionnaires. The analysis technique is through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the teacher had made a lesson plan with a scientific approach but the teacher had not explained it explicitly, systematically and comprehensively because the teacher found it difficult to determine the approach and model used during bold learning in each meeting. The implementation of learning by teachers has used a scientific approach, including the process of observing, asking questions, gathering information or trying, associating or reasoning and communicating but in its implementation it is still not optimally carried out there are several obstacles between passive students in learning, limited learning time and lack of ability of educators in learning. implement a scientific approach. Teachers use authentic assessments to assess the competence of attitudes, knowledge and skills of students. The teacher has not completed the assessment instrument and rubric because the teacher is not used to using the assessment instrument.

Abstract

The purpose of this study was to determine the implementation and effectiveness of the discovery learning model in improving learning outcomes on digestive system material. The subjects of this research were 26 students of class VIII-G SMPN 54 Surabaya. This research method is descriptive quantitative research design with one group pretest posttest design. The instruments used were pretest and posttest sheets each with 12 multiple choice questions and discovery learning implementation sheets. The results of the implementation of discovery learning obtained a very good category in 4 modes. The results of the homogeneity test state that the data are homogeneous with a significance level of 0.06. In the normality test, the data is normally distributed with a significance level of 0.39. The dependent t-test shows alpha 0.00 so that it is known that there is a significant difference between the pretest-posttest learning outcomes. The result of the implementation discovery learning is effective in improving learning outcomes on digestive system material.
