This study aims to investigate the effect of Science, Technology, Engineering, and Mathematics-Project Based Learning (STEM-PjBL) and discovery learning on students' problem-solving abilities. The research is a Quasi-Experiment with a Nonequivalent Pretest-Posttest Control Group Design. The participants involved are 53 students of class X from a high school in Malang, where 28 students studied with STEM-PjBL, and 25 students studied with discovery learning. This research was conducted on the subject of impulse and momentum. In this analysis, researchers have developed problem-solving tools with a particular field approach to impulse and momentum topics in order to obtain an instrument with a reliability of  0.81. This instrument collects student problem-solving data before and after learning both in the experimental class and in the comparison class. Problem-solving skills data were analyzed using descriptive statistics and inferential statistics. The results showed a significant difference in the scores of students' problem-solving abilities in the experimental class and the comparison class (p<0.05). The problem-solving ability in the experimental class (Md=78.74) was higher than the comparison class (Md=70.00). In STEM-PjBL learning, students are better trained and challenged to solve problems in everyday life. Compared to the comparison class, learning in the experimental class is more able to accommodate students' ideas and make students more interested in learning. In conclusion, STEM-PjBL has a significant positive effect on improving students' problem-solving abilities rather than discovery learning.

Penelitian ini bertujuan untuk mengembangkan materi pembelajaran digital untuk pelajaran bahasa Inggris. Responden dalam penelitian ini dibatasi pada siswa kelas XII Multimedia dan Keperawatan SMK Atlantis Plus Depok. Metode yang digunakan adalah Research and Development (R&D) dengan menggabungkan model penelitian ASSURE model development. Untuk melihat kelayakan model yang dikembangkan, pengembangan materi pembelajaran digital, peneliti ahli melakukan beberapa tes, uji coba kelompok kecil, dan uji coba lapangan dengan indikator bagaimana sikap dan hasil belajar siswa. Hasil penelitian menunjukkan ketiga prototipe akan menjadi desain yang potensial bila digunakan pada saat pembelajaran. Terlihat bahwa 29,73% sangat menarik dan 70,27% siswa memiliki sikap menarik terhadap materi pembelajaran digital yang dikembangkan. Selain itu ketuntasan siswa mencapai hasil belajar yang ditunjukkan sebesar 90% untuk siswa kelas XII Multimedia dan XII Keperawatan pada tahap uji coba lapangan yang berjumlah 37 orang adalah 87,56.

This study aims to analyze students' conceptual  understanding and their difficulties in grasping the static fluid concepts after they learned throughout integrated e-formative assessments in collaborative inquiry. This mixed-method research involved 28 senior high school students.  Students studied static fluid concepts with a collaborative inquiry strategy supported by the implementation of web-based formative assessment. Students' conceptual understanding and their difficulties were assessed using multiple-choice questions with the reasons (r= 0.75.). The result showed that students' conceptual understanding was improved after learning, which is indicated by the moderate normalized gain value (0.5374), and the strong effect size (2.772). However, there were still some difficulties that students have regarding factors that influence buoyancy. Providing more portion of the conceptual discussions and practising problem-solving during learning through e-formative assessment were recommended. Learning difficulties that have been found in this study can be considered and anticipated by teachers in teaching static fluid topic.                                                                         Â

This study aims to determine the effect of the integrated assessment for Learning (AfL) which is assisted by the Tryout application in scientific approach on students' conceptual understanding. This study used a quasi-experimental method with a pretest-posttest control group design. This research was conducted at a high school in Malang with a sample of two classes by a random cluster sampling technique. There were two classes involved, namely one as an experimental class (using an integrated AfL assisted with a tryout application in scientific approach) and one as a control class (using a scientific approach through assignment instructions). Thirthy four students in each class were tough the work and energy topic. The test instrument used was 20 reasoned multiple-choice questions with a reliability of 0.62. Data were analyzed using descriptive analysis and inferential statistics. The results showed that there was a significant difference between the posttest mean scores of the experimental class students and the control class students (p = 0.017). Descriptive analysis showed that the mean scores of posttest students for the experiment and control class were 61.76 and 54.26, respectively. That means that the conceptual understanding of students who learn with integrated AfL that assisted by tryout application in scientific approach was higher than students who learn with the scientific approach through assignments.

Science, technology, engineering, and mathematics (STEM) education has recently been gaining popularity in a number of countries. This seems to have ramifications for increasing the intensity with which professional development programmes are implemented at both in-service and pre-service teacher levels. The present study provides a systematic literature review on scientific articles published between 2015 and 2021, examining how STEM teacher professional development programmes (STEM-TPD) led in the pre-service teacher corpus. Following a screening process, 66 studies were found to be eligible and in compliance with the review criteria. The review's findings indicate a positive trend in STEM-TPD scientific articles, with an increase in publications from year to year in many countries. The majority of studies were conducted in the United States and Turkey using various research methods. The STEM-TPD programme is carried out in three areas, namely, included in existing courses, conducted outside of lectures, and carried out on newly developed courses. We also ultimately discuss the seven most frequently used elements of STEM-TPD and the types of participant collaboration.

Every student needs feedback to understand a scientific concept deeply. However, with a large number of students in each class, individual feedback is a challenge for teachers in Indonesia. Although there have been many studies conducted to maximize the giving of personal feedback, studies conducted by ensuring the consistency of a student's knowledge of a concept before providing feedback are rarely disclosed. This study aims to develop computer-assisted formative feedback (CAFF) based on students’ cognitive resources. Besides, this study also intends to determine student perceptions related to the use of CAFF. This current study involved two experts as advisers in the development process and 31 high school students who acted as participants in the pilot phase. CAFF could identify the students’ cognitive resources and then provided interactive feedback to students based on it. Therefore, it will be beneficial to associate students’ prior knowledge with scientific concepts. Instead of giving feedback by showing whether or not students' answers are correct, displaying the exact concept text, or providing general instructions to the right concept, CAFF presents feedback by showing students' cognitive resources then followed by the interactive explanation associated with specific cognitive resources. Students shared positive perceptions about the program. Cognitive resource diagnoses and forms of feedback in the CAFF model can be further developed on more nuanced topics.
