The Indonesia government has begun to focus and pay attention to the quality of education in Islamic Boarding School. Education is a provision for the future to create quality human resources. Education is strongly linked to the 21st century, where education has rapidly developed in science and technology to generate worldwide competitiveness. Students' higher-order thinking skills are fundamental, where this thinking ability is an ability to understand and find solutions to problems in varied and different ways. An appropriate learning approach must support Higher-order thinking skills. Higher-order thinking skills are intelligence with specific knowledge that leads to reasoning, analytical skills, problem-solving, and critical and creative thinking skills. Higher-order thinking skills are the major objective of educational institutions in implementing education that uses a quasi-experiment. Participants consisted of Islamic Boarding School students, ten male- and ten female students. A STEM-based video is a learning approach that can help students analyze, solve problems, investigate a phenomenon, create skills in students, and produce higher-order thinking skills. This study's STEM-based Video approach process is designed to solve functional mathematics problems in real life concerning geometry.

STEM only recently became part of the official Chinese public school curriculum in 2017 and suggested to be included in the primary school curriculum in 2018. This study shares findings from 79 Chinese pre-serivice early childhood teachers participating in a variety of hands-on STEM activities over a two week period. A follow-up question session was conducted with the translator as well. This training was offered outside of normal class times as a professional development. Data showed significant differences between the pre- and post- surveys along with strong relationships between main categories. Indications are that the sessions helped to promote the participant’s interest, perception, self-efficacy in STEM, as well as, thoughts toward STEM/science teachers and classes in their current program. Findings most strongly indicated that the sessions aided understanding of STEM and that STEM could be fun in terms of both learning and teaching. Overall, it appeared that the professional development sessions were meaningful for the participants and highlighted STEM practices and concepts in a positive light.

This research aimed to analyze students' Higher Order Thinking Skills (HOTS) using a two-tier multiple choice (TTMC) test instrument. This study used a descriptive quantitative method with a purposive sampling technique. The instruments used are multiple-choice tests with free reasoning, the TTMC test for quantitative data, interview guides, and learning observations for qualitative data. Anderson and Krathwohl's Bloom taxonomy revision (2001) cognitive instrument used to classify HOTS. The results showed that the higher-order thinking skill profile has an average score of 63,21 and dominated good. Students' cognitive level of analyzing/C4 (74,35%) is more dominant compared to cognitive evaluating/C5 (68,90%) and creating/C6 (63,24%). The hormonal regulatory subconcept gets the highest correct answer average with a percentage of 89,74%, and the contraceptive method subconcept gets the lowest correct answer average with 35,90%. One factor that influences the high and low percentage of the correct answer for each subconcept is the level of difficulty of the question; medium (enough) in the contraceptive method and too tricky in the contraceptive method. Analysis of answer patterns based on the results of a TTMC test shows that students are better able to answer questions on the first tier than answering on the second tier.

Design technological tools from basic sciences would be an excellent way for students to learn about Science, Technology, Engineering, and Mathematics (STEM) applications. Nowadays, young people are more connoisseurs of computer tools and gadgets than other generations. They could use those aptitudes with correct stimulation and orientation to generate new knowledge or improve technological applications in developing countries like Colombia. Designing or improving technology starting from basic knowledge and developing cheap technology is essential for the development of a society. We used a case study in this work, due to COVID 19 pandemic, we propose the design and creation of a prototype of a spirometer started from a class activity to put into practice the knowledge acquired in theoretical class and let students observe and implement physics applications. As a result, elemental physics course students achieve testing it on real people and compare it with known results. The students' spirometer prototype was made with inexpensive implements starting with the knowledge learned in the classroom. With it, students tried it on actual patients, letting them get measurable data consistent with known results from the literature. These experiences increased students' interest in science and its applications. This work shows us that applying STEM methodology from basic levels to practical uses could motivate young people to learn and improve their skills in those topics and see science as a way of life.
