ABSTRACT [The Effectiveness of Using a Model Problem-based Learning (PBL) to the Results of Physics Learning on High School Students 9 Lubuklinggau]. The objective of this study was to determine the effectiveness of the use of problem-based learning model. The research method used experiments with the form of Nonequivalent Control Group Design. The sample in this research is the students of class XI A and class XI B SMA N 9 Lubuklinggau City which amounted to 50 students. The  technique of collecting data in this research is a test. The test is in the form of pretest and finally test (posttest). The purpose of holding initial and final tests to determine the effectiveness of Physics learning with PBM model and conventional learning. The test instrument that was made before the test was tested was done by panelists test using Intracorelation class coefficient (ICC). Data analysis technique used in this research is t-test. The results showed that there are differences in student learning outcomes taught with Problem-Based Learning model (PBM) with students taught with conventional learning model. The difference can be seen in the result of t-test which yields t-count> t-table (3,98> 2.01). The effectiveness of using the PBM model in the experimental class is 13.5% better than in the control class. Keywords: Effectiveness; model; PBL; learning outcomes.

The purpose of the study was to analyze the effect of the blended learning model towards learning outcomes of the comprehension concepts and economic problems solving of Private Islamic High School students in Nganjuk Regency. The study used an experimental method, with a quasi-nonequivalent control group design. The research was conducted at Private Islamic High School Al Manar Prambon Nganjuk. The samples were conducted based on students' characteristics and similarities in economic topics. The experimental class was assigned to XI Social 1 and the control class was XI Social 2. The analysis technique used was descriptive statistical technique and two-ways MANAVA. Descriptive statistics were seen from the mean, standard deviation, variance, and presentation. The results of the MANAVA test analysis when viewed from the centroid pillar's trace, Wilks' lambda, hotelling's trace, and Roy's lambda root in the experimental class had a significance value of 0.000. The value was transformed to the Fisher distribution or F test, then it is smaller than α ˂ 0.050. The study shows that the blended learning model has an effect on the learning outcomes of comprehension concepts and economic problems solving of Private Islamic High School students.

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.

The study aimed at examining the effect of adopting blended learning on Moroccan high school students’ English language proficiency. This has been essentially achieved through relying both on face-to-face classroom interactions and using “Google classroom”, which is a free online learning platform.  The researcher opted for a quasi-experimental design to gauge the impact of implementing a blended learning model on the research sample. This study enlisted the participation of 79 Moroccan first-year Baccalaureate students who were divided into two separate but homogenous groups. The experimental group was taught using the blended learning model, and the control group was tutored in a traditional learning environment. The mean scores’ differences of the pre-test and the post-test asserted that, in comparison to the face-to-face learning, the blended learning model adopted was significantly impactful in improving the language proficiency level of the treatment group. However, no significant gender differences were observed in this regard. In essence, this piece of research has placed much emphasis on the idea that the efficient incorporation of ICT, particularly blended learning, into the learning/teaching process can help satisfy students’ needs, increase their motivation, and eventually enhance their language mastery.

This study aims to see how the efforts in improving the mathematical problem solving ability of high school students by learning STAD type cooperative strategies. This research is based on the importance of mathematical problem solving abilities that must be possessed by students, but the reality on the ground that these abilities are still very low. This research is an experiment with a pretest-posttest control group design. This is done in order to find out how much improvement in the ability to solve mathematical problems taught by learning mathematics in STAD type cooperative strategies. For the experimental group, students are taught with STAD type cooperative strategies, while in the control group, students are taught by direct learning. The population of this study was high school students, while the sample was students of class XI IPA of Laksamana Martadinata Medan Private High School. Five classes were randomly selected, class XI IPA 3 class as the experimental class and XI IPA 1 as the control class. The instrument used in the form of problem solving problems. Based on the results of the analysis, it can be concluded that: 1) there is a mean difference between students who are taught with STAD type cooperative strategies and those who are in direct learning. 2) Improvement of students' mathematical problem solving abilities that get cooperative learning type STAD gets direct learning ineffective.
