This development research aimd to: (1) Develop simple thermochemical teaching aids (2) Practical activities with the concept of Green chemistry that were environmentally friendly and safe to use (3) Obtain teacher responses to thermochemical teaching aids with Green chemistry as an alternative to the limited pre-practicum facilities. The development model used in this research was the 4-D model by Thiagarajan, Semmel, and Semmel which had been modified from four stages to three stages, namely: (1) Define (2) Design and (3) Develop (development). The stages carried out include (1) preliminary studies (2) product development and (3) product testing. The results of the preliminary study indicated that the development of teaching aids as a substitute for practicum activities was needed due to the limited existing facilities and infrastructure. Also, because thermochemical material had a high level of understanding and the abstractness of the concept, it was necessary to carry out practicum activities. The use and development of calorimetry props was an alternative in the implementation of thermochemical material practicum activities and by utilizing waste, it was possible to present simple calorimetry props that were environmentally friendly and safe to use. The results of product development in the form of props obtained the validity of the material with the results of 0.89 and the validity of the media with the results of 0.90, therefore the validation results of the props were categorized as valid. The practicality of the teaching aids was Green chemistry 88%, the result shows that the teaching aids developed were very practical so that these props were suitable for practicum. While the results of the teacher's response to the teaching aids with an overall average of 3.75 (maximum score of 4), based on these results indicate that the overall response of students to the teaching aids was very good.

In primary schools, students are given lessons that can be used to develop their character and various potentials, one of them is science subjects. The CLIS model can be used as an alternative learning model in teaching science because it contains constructivist learning elements that lead to meaningful learning. The purpose of this study was to analyze the effectiveness of the constructivist learning model using Children Learning In Science (CLIS) type in improving student learning outcomes. This study used a quasi-experimental method. The sample was taken using a random cluster technique were students of grade V SDN 2 Patikraja as the control class and students of grade V SDN 1 Notog as the experimental class. The data analysis used was a one-sample proportion test, N-Gain analysis, and independent-sample t-test. The results show that the use of the CLIS constructivist learning model is effective in improving student learning outcomes compared to learning with the expository method. This is evidenced by the increase in student scores before and after the implementation of the CLIS constructivist learning model is in the medium category, students in experimental class achieve classical completeness >75%, and the average learning outcomes of the experimental class is higher than the control class, as well as students shows positive responses. So this research can be helpful for the students and the teachers in learning sains.

Learning outcomes are important to form intelligent and skilled humans. This study aims to determine the effectiveness of inquiry worksheet with pair checks approach to improve learning outcomes in the cognitive domains and scientific attitudes. The research design used was an experimental control group with pretest-posttest. The research population was eighth grade in SMP N 1 Semarang. The research sample was taken using a simple random sampling technique. This research applies an inquiry worksheet with a pair checks approach for experimental classes and regular worksheet for control classes. The significance test of learning outcomes in the cognitive domain shows differences in learning outcomes for the two samples. The N-Gain value measured the increase in learning outcomes in the cognitive domain. The N-Gain value for the experimental class was 0.39, which was in the moderate category. The N-Gain value for the control class is 0.27 which was in the low category. The result of the observation shows that the inquiry worksheet with the pair checks approach is not effective in improving scientific attitudes. Students' scientific attitude has decreased for every meeting because of constraints for online learning as a result of the pandemic Covid-19. The student response to the application of the inquiry worksheet with the pair checks approach was 82.21% which was in the very good category.

Penemuan konsep materi pembelajaran secara mandiri dapat mempengaruhi kemampuan kognitif dan psikomotor peserta didik. Hasil observasi di SMAN 1 Karangtengah Demak menunjukkan bahwa pembelajaran masih berpusat pada guru sehingga kemampuan peserta didik dalam menemukan sendiri konsep materi masih kurang, hal ini menyebabkan rendahnya kemampuan kognitif dan psikomotor. Untuk menghindari hal tersebut diperlukan model pembelajaran yang sesuai yaitu inkuiri terbimbing. Guru belum menerapkan pembalajaran berbasis internet yang dapat membentuk sikap mandiri pada peserta didik, sehingga diperlukan pembelajaran berbasis internet seperti blended learning. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan inkuiri terbimbing berbasis blended learning terhadap kemampuan kognitif dan psikomotor peserta didik kelas XI MIPA SMAN 1 Karangtengah Kabupaten Demak. Metode penelitian yang digunakan adalah eksperimen dengan pengambilan sampel menggunakan teknik cluster random sampling, diperoleh kelas XI MIPA 1 sebagai kelas eksperimen dan XI MIPA 4 sebagai kelas kontrol.
