One of the skills that must be possessed by students in the 21st century is collaborative ability. Collaborative skills are abilities possessed by individuals in the form of groups to exchange thoughts or ideas and work together to achieve the expected goals. Increasing collaborative skills in students has a positive impact, namely producing more knowledge than just completing work independently and students can exchange ideas to be able to solve problems encountered in the learning process obtained.The efforts made in this study by applying the problem based learning (PBL) learning model to be able to improve collaborative abilities and learning outcomes learners. The use of the PBL learning model can improve scientific attitudes and student learning outcomes. The PBL model can improve learning outcomes and students' communication skills. The problem-based learning model can assist teaching staff in undergoing the learning process because it can improve student learning outcomes. Based on the background that has been formulated, the purpose of conducting this research is to determine the effectiveness of the PBL model in improving collaborative abilities and student learning outcomes in class XI reproductive system material.

The Problem Based Learning learning model is an innovative learning model that can provide active learning conditions to students. The distinctive feature of this learning model is that it involves students to solve a problem through the stages of the scientific method so that students can learn knowledge related to the problem and at the same time have the skills to solve problems. The research objectives were: (1) to describe the quality of learning mathematics through the Problem Based Learning model at SMP Negeri 4 Hiliserangkai. (2) Describe student learning outcomes in mathematics, especially problem solving through the Problem Based Learning model at SMP Negeri 4 Hiliserangkai. This research was conducted in class VIII of SMP Negeri 4 Hiliserangkai semester 1 of the 2021/2022 academic year with a total of 20 students. Based on the results of this study, the average quality of student learning in cycle I was 57.35%, which was classified as poor, while in cycle II, 79.41% was classified as good. And the average student learning outcomes in the first cycle is 62.5% in the sufficient category, and in the second cycle is 81.61% in the good category, this has reached the target set at 75%.

One part that cannot be separated from efforts to improve learning outcomes is improvement in the form of innovative learning media. By using learning media in the teaching and learning process can help teachers to clarify the presentation of material so that it is verbal and provide stimulation and arouse student learning interest. The purpose of this study is to determine the effect of using instructional media on student learning outcomes using the Power Director video on the material of the name of the capital city and currency of ASEAN class VI at UPT SDN 317 Gresik. This study uses the True-Experimental Design method using the PretestPosttest Control Group Design. Data collection was carried out in two meetings. Two classes were obtained as research samples by dividing class VI students into two classes, namely VI A as the control class and VI B as the experimental class. To determine the effect of using Power Director video media, students were given PreTest and Post-Test. Pre-test is given to students before being given treatment at the beginning of learning while post-test is given after receiving treatment at the end of learning. From the results of hypothesis testing it is also stated that Ha is accepted with the provisions of 𝑡𝑐𝑜𝑢𝑛𝑡(3,042) > 𝑡𝑡𝑎𝑏𝑙𝑒 (2,262), Thus it can be concluded that Media Video Power Director has an effect on student learning outcomes in social studies class VI at UPT SDN 317 Gresik.

This research was conducted on Catholic students in class X at SMAN 1 Palangka Raya because the researcher experienced that the learning outcomes of the students were not optimal. Theerefore this study aims to improve the learning outcomes of Catholic students in Catholic Religion subjects, in class X, with the Problem Based Learning model. The object of observation in this study was cognitive student learning outcomes and the application of the elements of faith and morality to humans (Pancasila Student Profile). The outcomes were: in cycle I, only 18% included the proficient category, 45,45% included the proficient category, 33.4% included the appropriate category. Whereas in cycle II students who reached the proficient category reached 64%, the proficient category 36% and the feasible category 0%. Observational data related to the application of moral elements to humans in cycles I and II show that, on average, the achievement of the P5 indicator that has been determined by the researcher has increased by 45%.

This study aims to analyze the effect of problem-based learning (PBL) model on student learning outcomes in class XI Light Vehicle Engineering subjects at SMK Teknologi Plus Padang. The PBL model was chosen to increase students' activity, understanding, and interest in learning through contextual learning that can develop critical thinking skills. This study used quantitative methods with a Quasi Experiment design, involving 21 students in the experimental group and 21 students in the control group in the 2024/2025 school year. The Shapiro-Wilk normality test and Levene's homogeneity test showed that the pre-test and post-test data were normally distributed and homogeneous. The results of the independent sample t-test revealed a significant difference between the experimental group (average 77.90) and the control group (average 50.48) with a sig (2-tailed) value of 0.001 <0.05. These results indicate that the application of the PBL model can significantly improve student learning outcomes. The implications of this research provide evidence that problem-based learning models are effective in creating an active, collaborative, and meaningful learning environment, so they can be implemented in various learning contexts.

The purpose of this study was to determine the difference between student learning outcomes in mathematics using the Student Team Achievement Divisions (STAD) learning model and the Team Assisted Individualization (TAI) learning model. The research method is descriptive quantitative with a quasi-experimental approach, and a two-group posttest only control design. Samples were taken by means of convenience sampling. The data collection technique is a test instrument by looking at the learning outcomes. The results and findings, based on the results of hypothesis testing using the t-test, obtained that t count is greater than t table of 3.179> 1.995 with a significance level of 0.05. These findings are supported by the calculation of learning outcomes for experimental class I using the Student Team Achievement Divisions method with the average value is 70.01, this shows a higher value than the experimental class II which uses the Team Assisted Individualization method which averages 66.90. The conclusion is that there are differences in the learning outcomes of students who are taught using the Student Team Achievement Divisions model with students who are taught using the Team Assisted Individualization learning model. The Student Team Achievement Divisions learning model produces higher learning outcomes and is recommended to be used in teaching all mathematics materials at all levels

The purpose of this research is to know the difference of mathematical representation skill, the result of science learning and its influence on problem-based learning and discovery learning model. The population of this study was 16 students of PGSD FKIP University of Lampung. Among 534 students, there were two experimental classes consisting of 35 students and each was determined through cluster random sampling. The data on mathematical representation skills and learning outcomes of science were obtained through a description test, five questions for assessing mathematical representation skills, and ten questions for assessing science learning outcomes. From the instruments that had been tested to 30 respondents, it was obtained a valid and reliable instrument with a score of 0.505 for mathematical representation skills, and 0.832 for learning outcomes. Furthermore, the data were analyzed by using normality test, homogeneity test, independent sample t-test, correlation test, and simple linear regression test. The results showed that there was no difference in the result of mathematical representation skill and science learning outcomes, between the problem-based learning model and real discovery. But there is a positive and significant linear influence between the mathematical representation skill and the learning outcomes of science, through a problem-based learning model of discovery.
