Abstract

This study aims to analyze the validity and reliability of Google Form-based descriptive questions in assessing the scientific creativity of high school science students. Scientific creativity is an essential skill in science learning that includes flexibility of thinking, originality of ideas and elaboration in developing concepts and solving problems. By increasing the use of digital technology in learning evaluation, Google form becomes one of the platforms that offers convenience in compiling questions, collecting data in real-time and analyzing results systematically. This study uses a quantitative descriptive method by testing the validity and reliability of the descriptive question instrument through statistical analysis. The results of this study indicate that the Google Form-based assessment instrument has high validity with an average correlation value above 0.5 and good reliability with a consistency level above 0.7. In addition, this instrument is able to measure students' scientific creativity in answering questions based on three main indicators, namely flexibility, originality, and elaboration. This study shows that Google form can be used as a valid and reliable evaluation tool in assessing the scientific creativity of high school science students, but collaboration with other assessment methods is still needed to optimize the measurement of aspects of idea exploration and problem solving in more depth.

Abstract

Pemahaman konsep suhu dan kalor merupakan aspek fundamental dalam fisika yang memiliki peran penting dalam berbagai bidang ilmu dan kehidupan sehari-hari. Namun, masih banyak siswa mengalami kesulitan dalam memahami konsep ini akibat metode pembelajaran yang kurang interaktif dan minimnya eksperimen. Penelitian ini bertujuan untuk menganalisis peran kreativitas ilmiah dalam meningkatkan pemahaman siswa terhadap suhu dan kalor melalui pendekatan pembelajaran yang inovatif. Metode yang digunakan adalah kuantitatif deskriptif dengan survei terhadap siswa kelas X SMA yang telah mempelajari suhu dan kalor. Data dikumpulkan melalui tes pemahaman konsep dan kuesioner kreativitas ilmiah, yang kemudian dianalisis menggunakan uji validitas dan reliabilitas. Hasil penelitian menunjukkan bahwa kreativitas ilmiah berkontribusi positif terhadap pemahaman konsep suhu dan kalor. Meskipun sebagian besar butir soal dalam instrumen asesmen memiliki validitas dan reliabilitas yang baik, beberapa butir perlu direvisi untuk meningkatkan akurasi pengukuran. Diperlukan strategi pembelajaran yang lebih inovatif, seperti eksperimen laboratorium, simulasi interaktif, dan penerapan konsep dalam kehidupan sehari-hari, agar siswa dapat memahami materi dengan lebih baik.

Abstract

After inquiry learning research is carried out, it is necessary to investigate problems and find problems based on clear concepts based on observations. Creativity is the ability to create something new. The proposed activities are based on physical phenomena through experiments. Prior knowledge of a problem may detract from an investigation, as it may prefer to retain known evidence rather than devise new alternatives. Creativity is the ability to think to come up with solutions, ideas, ways, products as solutions to existing problems. Innovative is the process of doing something in a new way. The process skills of discovering and developing concepts, theories, legal principles and facts are science process skills (KPS). Based on investigations and problem findings, creative inquiry learning with a process skills approach is used. The method in this research is analysis of indicators of inquiry learning syntax (problem formulation, hypothesis formulation, data collection, hypothesis testing and conclusions), creativity (KE experimental group and KK control group) and science process skills (KE and KK). The concepts developed mutually support inquiry, creativity and process skills. Students' ability to investigate and find problems can be realized.

Abstract

This study aims to determine the effect of TPACK-based differentiated learning on high school students' problem-solving abilities and motivation. The study, conducted at Private Senior High School PAB 8 Saentis Sei Tuan, used a quasi-experiment method with two classes: the experimental class, which used the differentiated problem solving model based on TPACK, and the control class, which used the conventional school learning model without differentiation. The results of this study indicate that the average post-test score for student problem-solving abilities in the experimental class was higher than in the control class. Statistical testing using two-way ANOVA showed that the problem-solving skills of students taught with the TPACK-based differentiated learning model demonstrated a significant influence between the learning model and motivation on students' problem-solving skills, as well as an interaction between the TPACK based problem posing learning model and motivation in terms of problem-solving skills. These findings have practical implications for educators, providing evidence that the TPACK-based differentiated problem-posing learning model is more effective in improving students' problem solving abilities than the conventional learning model, with learning motivation also playing an essential role in enhancing student problem-solving skills.
