Sampel yang dipilih adalah kelas X TKJ 1 sebagai kelas eksperimen dan X TKJ 4 sebagai kelas kontr… Show more
“…Based on the T-test results, it shows that there is a significant difference between the pretest and posttest. Furthermore, the N-Gain test showed a score 88.7 (N-gain > 70) and is classified as high, so it can be said that the STEM-PjBL worksheet is effective in improving students' critical thinking skills (Kurniawan et al, 2019). This is in accordance with the statement by Usboko et al, (2021) and Linh et al (2019) that learning using the STEM-PjBL approach has an effect on students' critical thinking abilities.…”
This research aims to develop STEM-PjBL worksheets on eight-gr ade human excretory system material to lift students' creative, critical, and computational thinking skills. This R&D research uses the Borg & Gall model. The data collection instruments were interview sheets, validation sheets, questionnaire sheets, and also tests (pretest and posttest). The results show that the STEM-PjBL worksheet is feasible and practical as a learning instructional. The data on the effectiveness of learning media obtained an N-gain score of 88.7 (N-gain >70) and is included in the high category, this shows that STEM-PjBL worksheets can improve students' critical thinking skills. The average score for all aspects of the creative thinking assessment was 81% (creative) and the average score for computational thinking skills was 80% (very high). These results show that STEM-PjBL worksheets can improve students' creative, critical, and computational thinking abilities.

“…Data penelitian mengenai keterampilan berpikir kritis peserta didik menunjukkan bahwa sebagian besar peserta didik telah berada pada kategori berpikir kritis yang baik. Keterampilan berpikir kritis peserta didik dipengaruhi oleh strategi pembelajaran yang digunakan oleh guru (Kurniawan et al, 2019). Guru biologi di SMA Negeri Palopo cenderung memberikan model jigsaw melalui metode diskusi sehingga dalam proses pembelajaran peserta didik dapat lebih aktif.…”
The development of information and communication technology demands that learners enhance their critical thinking skills to be able to filter accurate information, thereby achieving truth and a proper understanding of the knowledge around them. This is also expected to help improve students' learning outcomes. The research used in this study is quantitative descriptive research with the aim of determining the relationship between critical thinking skills and student learning outcomes in biology, specifically in the digestive system topic for Grade XI. The research subjects used were all Grade XI science students at SMA Negeri 3 Palopo. The determination of the subjects used the Slovin formula, resulting in a sample size of 147 students. The sampling technique employed was purposive sampling. Data collection in the research utilized two instruments: a critical thinking skills test consisting of 10 essay questions adjusted to the critical thinking skill indicators according to Ennis and a learning outcomes test consisting of 20 multiple-choice questions adjusted to the cognitive dimension indicators of Bloom's revised taxonomy according to Anderson & Krathwohl. Data on critical thinking skills and student learning outcomes were analyzed descriptively, and prerequisite tests were conducted using the Kolmogorov-Smirnov normality test and simple linearity tests. The relationship between critical thinking skills and student learning outcomes was tested using the product-moment correlation test, and the results obtained indicate a very strong and positive relationship between critical thinking skills and learning outcomes. This research is expected to provide insight to educators in their efforts to enhance students' critical thinking skills.
