Life skills are needed in this era of globalization to be successful in the school environment or outside of school. According to the 2019 World Economic Forum, the world's demand for STEM qualifications and skills is very high now and is likely to continue to increase in the future. Today, 75% of the fastest-growing industrial-scale jobs require skilled STEM workers. Faced with this, to be able to compete, the world of work requires people who can adapt to their new work environment. STEM can empower individuals with the skills to succeed and adapt to new work environments. To get individuals who have STEM skills, individuals who have 21st-century skills are needed. This is because in 21st-century skills 3 skills must be met, namely learning skills, reading and writing skills, and life skills. The purpose of this study was to determine the feasibility of the PBL-STEM module developed for prospective Biology teacher students as an effort to improve 21st-century skills. The method used was the Rosset-based RnD ADDIE model. The ADDIE Teaching Model includes 5 stages, namely analysis, design, development, implementation, and evaluation. The results of the material expert validation show that the average score of the material expert validation results shows a fairly good category with an average of 2.94. The results of practitioner validation show that the average score of practitioner validation results shows a good category with an average of 3.56. The results of the small group readability test showed that the average score on the small group readability test was in the good category with an average score of 3.39.

Teachers as education providers play a role in improving student learning outcomes. The quality of teacher performance is very decisive on the quality of educational outcomes because the teacher is the figure who most often interacts directly with students during the learning process. The purpose of the study was to determine the contribution of transformational leadership, education and training, and educational digital innovation to teacher performance in learning at SMP Muhammadiyah Ngawi. This type of research is causal associative research using a quantitative approach. Places of research in several SMP Muhammadiyah Ngawi. The data analysis technique used multiple linear regression analysis. The results showed that transformational leadership had a positive and significant effect on teacher performance with a significance value of 0.010 < 0.05. The education and training variables have a positive and significant effect on teacher performance with a significance value of 0.013 < 0.05. Furthermore, the education and training has a positive and significant effect on teacher performance 0.001 < 0.05. Taken together, the variables of the transformational leadership, the education and training and the digital innovation on teacher performance are simultaneously influential. Suggestions for the teacher research at SMP Muhammadiyah Ngawi are expected to help each other with the problems of other members in providing information related to teacher performance.

This qualitative-ethnography study described the critical thinking skill based on indicators of interpretation, analysis, evaluation, and inference in solving mathematical problem. The subjects of the study were the headmaster, math teachers, and ninth grade students of a public junior high school in academic year of 2020/2021. The data were collected through observation, field notes, interview, and documentation. Triangulation of sources and technique were used to ensure the data validation in this research. Data analysis technique was done inductively with continuous process along with the data collection. The results of the study showed high initial skills in mathematics become the basic need for the students in developing critical thinking skills based on indicators of interpretation. The improvement of critical thinking based on the indicator of interpretation is accustomed through problem-based learning. Critical thinking process based on the indicator of analysis is cultivated through collaborative learning. In this indicator, the students need special attention from the teacher. There is always the possibility for every student from each level to face difficulties in solving some problems without collaborating with others. The teachers can make more effort to optimize the students’ basic holistic skills in line with their knowledge and experience in order to improve students’ critical thinking skills based on the indicator of inference. In this indicator, teachers should guide the students to improve their critical thinking skills.

This article aims at arguing for the importance of the testing step when designing an educational application by taking a case study from the development of adaptive learning media. The media contains a set of in-struments that are specifically built to empower students' critical thinking skills. Three aspects that are con-sidered in testing this educational application are application validity at each stage of system development, measurement of the final system feasibility test for user needs, and system implementation by running learning media on the test sample. Implementation of testing on application products is carried out accord-ing to system requirements and models. The existence of the characteristics of adaptive media and the diver-sity of menus in the application implies the importance of doing a lot of improvisation when carrying out tests, such as determining the right test cases, choosing the appropriate test model and method, determining a suitable test environment, and considering several other aspects aimed at optimizing test results. obtained in order to ensure the quality of learning media products. This study analyzed the test data using Likert scale as an interpretation of the results of the validation assessment from the experts by referring to certain perceived standards of assessment. Meanwhile, the analysis of the data from the feasibility test results from a sample of 20 students using the system usability scale (SUS) instrument. The technique to test the effec-tiveness was using a pretest-posttest control group design with a sample of 98 students. Parametric/non-parametric data analysis was then applied to analyze the data on the results of testing the effectiveness or efficacy of adaptive media products in improving students' higher order thinking skills (HOTS). Based on the testing steps applied to the application of adaptive learning media, the results obtained that the product was considered feasible and effective in empowering students' HOTS. The study concludes that the educa-tional application testing that has been carried out is able to provide an objective and independent view of the application of adaptive learning media which will be useful in operational functions to understand the level of effectiveness in its implementation before being widely used in learning.

The Critical thinking is important in education because it encourages students to gain an understanding of more complex information. High critical thinking skills will lead students to find and conclude their understanding. The prolonged COVID-19 pandemic has made global changes in the implementation of learning. Until now, the learning process is still directed at the online learning model with the help of various Learning Management System (LMS) platforms. Conditions like this have implications for the decline in students' critical thinking skills in various aspects, such as inference, interpretation, explanation, analysis, evaluation, and self-regulation. This study aims at proposing an alternative learning approach, namely the enhanced-open learning model which is used to empower and improve students' critical thinking skills. This learning model was developed using the Research and Development (R&D) method and implemented with an adaptive hypermedia learning application media designed with the Luther development model. The sampling technique used was cluster random sampling on 98 students of informatics education in Surakarta City. The data were analyzed with the prerequisites for normality and homogeneity of the data before the Wilcoxon Signed Rank Test and Mann Whitney U test was carried out to determine the effectiveness of the model. The results of the increase in the gain score obtained from the experiment are in the aspect of interpretation of 93.18%, inference 76.74%, explanation 96.33%, analysis 97, 87%, evaluation 63.01%, and self-regulation 98.13%. Based on the experiments conducted, it is proven that the adaptive open learning approach has a very significant impact on improving students' critical thinking aspects so that it can be concluded that the model is effective in improving students' critical thinking skills.
