This research aims to analyze the content validity of instruments used at schools. In this research, content validity is measured from three aspects, namely material, construct, and language/culture/ethics aspects. The method used in this research uses quantitative descriptive methods. Content validity was assessed by 8 validators by filling a questionnaire. The results obtained from the validator are then analyzed by calculating the Aiken's V index. The Aiken's V value is used to ensure that the instrument used meets the content validity criteria and is categorized as suitable for use as a measuring tool. Based on analysis using Aiken's V, the averages obtained for the material, construct, and language/culture/ethics aspects were respectively in the very high, very high, and high categories. And overall the content validity of the instruments used in schools has met good content validity standards in the very high category. However, determining the criteria for a good assessment instrument is not only content validity, but also construct validity, empirical or item validity, and reliability. So, to further ensure that the quality of the end-of-semester assessment instruments used in schools is categorized as fully adequate, further research can be carried out by future researchers.

This study aims to evaluate the effect of the Problem Based Learning (PBL) model on students' critical thinking skills in understanding the material of RNA and DNA structures. The PBL model is applied as an active learning approach that involves students in solving real problems and is relevant to the biology material being studied. This study used an experimental design with a control group and an experimental group where the experimental group was taught using the PBL model, while the control group used conventional learning methods. Data collection was carried out through critical thinking skills tests before and after the intervention, as well as observations during the learning process. The results of the analysis showed that students who were taught using the PBL model experienced a significant increase in critical thinking skills compared to the control group. These findings indicate that the application of the PBL model can improve students' understanding and analytical skills of the structure of RNA and DNA, and can be an effective alternative in the biology learning process in schools. This study provides recommendations for the wider application of the PBL method in the context of science education to improve students' critical thinking skills.

Low student learning outcomes are a common problem found in the learning process. Learning models that are not yet varied are one of the causes of low student learning outcomes. This research aims to see the effect of the discovery learning model on the learning outcomes of class VII students at Bintang Langkat Junior High School. This research was carried out at Bintang Langkat Junior High School. The population in this study were all class VII students at Bintang Langkat Junior High School. The sample group was divided into 2 classes, namely the control class and the experimental class. Each class will be given a pretest and posttest. The instrument used was a multiplechoice test instrument with 20 questions. Before testing the hypothesis, the data was tested for normality and homogeneity. From the analysis results it was found that the samples were normally distributed and categorized as homogeneous. Next, a statistical hypothesis test can be carried out using the t test. The results of hypothesis testing with the t test show that H0 is rejected. So it can be interpreted that there is an influence of the use of the discovery learning model on the learning outcomes of Bintang Langkat Junior High School students.

This research is motivated by the low mathematical communication ability of students in expressing ideas and relating the knowledge students have to real situations. This study aims to determine the contextual learning model influences students' mathematical communication ability better than the direct learning model. This research is a quasi-experimental research. The population of this study were all fourth grade students at SDN 050660 Kwala Bingai, Stabat, which consisted of three parallel classes with a total of 89 students. The sampling system used was cluster random sampling with classes IVA and IVB classes being sampled. Class IVA as the control class consisted of 30 students and class IVB as the experimental class consisted of 27 students. Data analysis was performed by two-way analysis of variance (ANOVA). The results showed that the contextual learning model had a better effect on students' mathematical communication abilities compared to the learning model. This shows that the contextual learning model provides a good change in developing students' mathematical communication ability.

Learning outcomes in the independent curriculum in Natural and Social Sciences (IPAS) Phase B (for grades III and IV SD/MI/Package A) require that the learning carried out must be able to stimulate students to think at higher levels (HOTS ). This study discusses the analysis of HOTS content contained in IV grade IPAS textbooks for students. This research is a descriptive quantitative research. Data was collected using literature study techniques, documents, and questionnaires. Then, the percentage value of the HOTS load in the book by the data was calculated. The results obtained are interpreted to see the measurable level of thinking. There are 24 topics discussed and grouped into 8 chapters. Based on the results of the analysis of material content, creating (C6) around 12%, evaluating (C5) 12%, and analyzing (C4) 76%. While the items in the student's book, out of 33 questions scattered in the book, were found to be 12% at the C6 and C5, 73% at the C4, and 3% is C2. Overall, 98% content of the book is already contain HOTS. Based on the results, it can be assumed that the book is good for stimulating students to think at higher levels.
