This study aimed to determine the higher-order thinking skills of pre-service teachers through STEM-PjBL Model. The research method used was a quasi-experimental with one group pretest-posttest design. The N-Gain results mention the N-gain in both experimental and control classes that the physics learning process through the STEM-PjBL Model is 21% higher in improving higher-order thinking skills than Direct Learning. Improvement of students' ability to solve HOTS categorical questions in the experimental group taught by applying STEM-PjBL Model scored N-Gain 75% or 0.75, which increases the high category. In comparison, the control group led by applying the Direct Learning model achieved 54% or 0.54, meaning a moderate increase in categories. The results showed that learning using STEM-PjBL Model could improve higher-order thinking skills more than Direct Instruction Learning. The implications of this research include: gaining new knowledge that can be used as a pre-service teacher’, adding insight regarding STEM-PjBL Model that can be used to grow students' science process skills, assisting schools in improving the quality of students, and the quality of the physics learning process in schools.

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.

Tujuan penelitian ini adalah menganalisis kemampuan pemahaman konsep matematis siswa sekolah menengah pertama yang ditinjau dari gaya kognitif Field Independent (FI), Field Intermediate (FID), dan Field Dependent (FD). Subjek penelitian ini adalah adalah siswa MtsN Pandeglang 1 kelas IX-C berjumlahkan 20 siswa yang dikelompokkan berdasarkan gaya kognitif yang dimiliki oleh setiap siswa, setiap kelompok gaya kogitif diambil perwakilan 2 siswa dengan menggunakan metode purposive sampling untuk diukur kemampuan pemahaman konsep matematisnya. Kemampuan pemahaman konsep matematis pada penelitian ini memiliki tujuh indikator. Berdasarkan hasil penelitian ini kemampuan pemahaman konsep matematis siswa memiliki kesamaan dan perbedaan. Siswa dengan kelompok gaya kognitif Field Independent (FI) memiliki kesamaan kemampuan pemahaman konsep matematis, yaitu mereka mampu mencapai semua indikator yang terdapat pada kemampuan pemahaman konsep matematis. Siswa dengan kelompok gaya kognitif Field Intermediate (FID) memiliki perbedaan kemampuan pemahaman konsep matematis, salah satu siswa dapat mencapai semua indikator dan siswa lainnya hanya memenuhi beberapa indikator kemampuan pemahaman konsep matematis. Hal ini menunjukkan bahwa siswa yang termasuk dalam kelompol gaya kognitif yang sama belum tentu memiliki kemampuan pemahaman konsep matematis yang sama. Siswa dengan kelompok gaya kognitif Field Dependent (FD) hanya sedikit indikator yang mampu dicapai oleh siswa dalam indikator kemampuan pemahaman konsep matematis.

This study will analyze the influence of Good Corporate Governance in determining the value of the company through the Independent Commissioner and the Board of Directors. As a moderating variable, audit quality is used as measured by a dummy variable on the use of big four auditors. The sample used includes 31 companies in the food and beverage industry sub-sector and the miscellaneous goods industry sub-sector listed on the Indonesia Stock Exchange for the 2018-2020 period which were selected by purposive random sampling. After the multiple linear regression test and hypothesis testing as well as the coefficient of determination test, the results show that the Independent Commissioner and the Board of Directors have no effect on firm value, because the value created does not provide a significant increase for stakeholders. The same thing also happened to audit quality with the result that there was no effect or weakening on the creation of Company Value because investors did not consider the name of the auditor as long as the audit report was published.

The purpose of this study is to improve the understanding of the concept of prospective teachers in applied physics courses by applying the Starter Experiment Approach when the lectures take place. Starter Experiment Approach is an approach used as a tool for students to practice the skills of observation, because in this approach are consecutively trained to formulate problems, formulate temporary answers from the problem formulated (hypothesis), designing experiments, experimenting, and reporting results trial. The research method used quasi experiment with Pretest-Posttest Control Group Design. Research sample is divided into two classes, namely experiment class and control class. The experimental class uses learning with the Starter Experiment Approach learning model while the control class uses the conventional learning model. Based on the result of research, it is found that the average of N-gain understanding of student concept using learning model starter experiment approach is 0,74, mean of N-gain understanding of student concept with conventional learning equal to 0,23. These data suggest that the understanding of physics concepts using the Starter Experiment Approach learning model is higher than the understanding of physics concepts using conventional learning models. Then based on data analysis show that tcount = 14,196 and ttable = 2.01 (5% significance level). This means tcount> ttable, so it can be interpreted that there is a significant difference in the ability of student concept between student groups applying Starter Experiment Approach (SEA) and group of students using conventional learning model. So the application of Starter Experiment Approach (SEA) has a positive effect on the ability to understand the concept of prospective teachers in applied physics courses.
