This paper estimates an education production function using data on the College Scholastic Ability Test score and high school characteristics from Seoul, Korea, where, on entering high school, students are randomly assigned to schools within each school district. We derive a school production function by aggregating the individuals' potential outcomes under the random assignment and no cohort effect assumption. We find that the school production function coefficients differ between districts and that the single-sex school effect estimate is much larger than that found in previous studies.

Background and Study Aim. The COVID-19 pandemic has caused many athletes to interrupt their regular training programme. The change-of-direction performance is a highly critical parameter for fencing. This study aims to investigate the effects of the detraining process caused by the COVID-19 pandemic on the change-of-direction performance of fencers. Material and Methods. The study sample comprised 15 fencers (11 males, 4 females) who were competitors in the U17-20 age categories (mean age: 15.75±1.51 years; height: 170.30±7.68 cm; weight: 65.16±10.83 kg) in Turkey. All participants were high school students. Branch-specific change-of-direction tests (4-2-2-4-m shuttle and 7-m repeat lunge ability) were measured in the middle of the competition season and after the detraining period. The detraining period lasted 31 weeks due to the pandemic process.   Results. The results showed that participants were slower in the post 7-m repeat lunge ability test (23.32±2.21 sec.) compared with the pre-test (22.38±1.58 sec.) and participants were slower in the post 4-2-2-4-m shuttle test (6.43±0.54 sec.) compared with the pre-test (5.84±0.33 sec.) (p<0.05). Conclusions. The present study showed that long-term detraining reduces fencer’s change-of-direction performance.  Basic exercise programs can be arranged to reduce the rate of adverse effects during long-term detraining process.

This study aims to determine the effect of the Argument-Driven Inquiry (ADI) learning model application on the concepts mastery and argumentation skills of high school students on reproductive system material. The research method used quasi-experimental and non-equivalent control group design. The sample of this research were second-grade high school MIPA students in one of the public high schools in Bandung, which consists of 30 students in the experimental class and 33 students in the control class. The sample was taken by using the purposive sampling technique. The instruments used consisted of a concept mastery test in the form of multiple choices, an argumentation ability test in the form of an essay, and questionnaire of students’ responses to the ADI model. The results showed that the application of the ADI learning model significantly affected the students' concepts mastery on reproductive system material in the experimental class compared to the control class, especially in the cognitive aspects of C3 (applying). The results also show that the application of the ADI learning model significantly affects the ability of argumentation, especially on the warrant component. Student response data shows that students respond very well to the application of the ADI learning model. Therefore, the ADI learning model is recommended for biology teachers to improve students’ concepts mastery mastery and argumentation skills in other biological materials.

It is difficult for junior high school teachers to position and nurture their students who are still in transition in creative thinking when solving math problems. This study evaluates students' creative thinking process based on Wallas model (2014). The four stages of the creative thinking process according to Wallas include the preparatory, incubation, illumination, and verification phases. The purpose of this study is to describe the creative thinking process of students based on their basic ability level in solving math problems. This research applies giving test of geometric crater thinking ability by looking at homogenous student in kemampuandan interview for deepening. Subjects of junior high school students who categorized on the ability of high, medium, and low after the ability test. Variable of this research is the existence of junior high school students in solving math problems. By using qualitative descriptive method, data is analyzed through classification stage, data representation, and conclusion. In order to complete the results of data groupings used interview techniques to perform data triangulation. The results showed 1) there were 23.33% of students not complete and only reached the preparation stage, called the low category category; 2) there are 60% of students reach the illumination stage even though to this stage students take a long time, called the middle category category; And 3) 16.67% of students have been completed until the verification stage, called the high category category. Based on the deepening of the triangulation of the interviews, the students are correct in that category. For students with low and medium capability categories still require assistance when experiencing barriers to their creative thinking process, while high ability category students need enrichment material

Abstract This study aims to analyze the students’ mastery of concepts on the topic of energy during the distance learning when Covid-19 pandemic. The method used in this study is descriptive quantitative. The sampling technique used purposive sampling, where the determination of the study sample is based on gender. The sample in this study is 116 people. Students’ mastery of concepts refers to Bloom’s Taxonomy, namely C1 to C4. The instrument used was a cognitive ability test with 22 multiple choice questions. Data were analyzed using scoring techniques with the Guttman scale. The scores obtained are made into percentages and the results are grouped by category. The results showed that during the distance learning process, the students’ mastery of concepts was in the “enough” category with a percentage of 54%. Based on each aspect, the mastery of the concept in the C1 aspect shows an achievement of 81% with the “very well” category, 49% for the C2 aspect in the “enough” category, 57% for the C3 aspect in the “enough” category and 48% for the C4 aspect with the “enough” category. From the results of the study, efforts are needed to improve students’ mastery of concepts through appropriate learning strategies.

Problem solving is one of several important abilities a student must have. Problem solving is a planned process that mustbe done in order to get a certain solution of a problem that is not obtained immediately. One type of problem studentsmust solve is an open-ended problem. Open-ended problem solving for every student is certainly different from oneanother. The level of mathematical ability of students is one of the factors that influence these differences. This type ofresearch is a qualitative descriptive with the purpose to describe the profile of open-ended problem solving based onPolya’s steps viewed from mathematical ability level of junior high school students. Three students from grade VII arethe subjects in this research (one student having high mathematical ability, one student having moderate mathematicalability, and one student having low mathematical ability). This research uses instruments mathematical ability test, openended problem solving test, and interview guidelines. The results showed there were differences in the open-endedproblem solving profile on students with high, moderate, and low mathematical ability. Student with high mathematicalability can carry out all the steps of Polya’s problem solving. Student with moderate mathematical ability are able to carryout the step of understanding the problem, devising a plan, carrying out the plan, however there are indicators that are notfulfilled at looking back’s step they are using the other way to solve the problem and make conclusion. Student with lowmathematical ability can not show the adequacy of the data at understanding the problem’s step and can not carry out thesteps of devising a plan, carrying out the plan and looking back.
