/0 Comments/in /by

The research seeks to elucidate the impact of the PJBL (project based learning) learning paradigm on student academic performance at UPTD SMA Negeri 1 Sarudu. This research utilizes a quantitative approach, specifically the quasi-experimental method. The population in this study comprises class X pupils, whereas the sample consists of students from classes Xa and Xb, utilizing a saturation sampling strategy. Data gathering methodologies include pretest and posttest inquiries throughout the first and final sessions. The research shows that the PJBL learning model has a big effect on how well students learn at UPTD SMA Negeri 1 Sarudu. There is a big difference between the experimental class that gets PJBL and the control class that doesn’t. The Mann-Whitney test revealed a score of 1,174 for the experimental class and 779 for the control class, with a significant value of 0.005, indicating acceptance of the hypothesis. Therefore, we concluded that the PJBL learning model had an influence on the biology learning outcomes of students at UPTD SMA Negeri 1 Sarudu.

Development of Mathematics Learning Tools Based on Education for Sustainable Development (ESD) Using the Outdoor Learning Mathematics Method to Enhance Mathematical Connections in Junior High School

/in /by

This research aims to develop mathematics learning tools based on Education for Sustainable Development (ESD) using the Outdoor Learning Mathematics method with the goal of enhancing mathematical connections of junior high school students in statistics. The research method employed is a mixed-methods approach combining qualitative and quantitative methods, both conducted through developmental research comprising planning, development, and evaluation stages. The sample for this research was two classes at SMPN 1 Tempeh with homogeneous mathematical abilities, where one class will be used as the experimental group and one class as the control group. Determining the research area using a purposive area sampling technique with the consideration that learning using the outdoor learning mathematics method with educational sustainable development (ESD) based learning tools has never been implemented at SMPN 1 Tempeh. The selection of eighth-grade classes is based on the consideration that statistics material is currently being taught in eighth grade, and eighth-grade students have not been subjects of research for similar studies before.  The learning tools developed are designed in accordance with ESD principles and utilize outdoor mathematics learning approaches to enhance students’ understanding and skills in statistics. The results from Hypothesis Testing for Pretest indicate that a p-value of 0.648 is obtained, where this value > 0.05 means H0 is accepted and H1 is rejected. Therefore, it can be concluded that there is no difference in the mean between the control and experimental groups in the pretest. Whereas the result of Posttest Hypothesis Test indicate that a p-value of 0.028 is obtained, where this value < 0.05 means H0 is rejected and H1 is accepted. So the use of ESD-based mathematics learning tools with the Outdoor Learning Mathematics method is effective in improving students’ mathematical connections in statistics. The implication of this research underscores the importance of integrating mathematics education with sustainable development principles to reinforce students’ understanding and skills in mathematics while also fostering awareness of environmental and social issues.

This study concludes that there is an effect of digital literacy and the use of printed books on the learning outcomes of primary school students in Elementary School Gugus 2 Tlanakan Sub-district, Pamekasan Regency. There is an effect of digital literacy on the learning outcomes of primary school students in Elementary School Gugus 2 Tlanakan Sub-district, Pamekasan Regency. There is an effect of using printed books on the learning outcomes of primary school students at Elementary School Gugus 2, Tlanakan sub-district, Pamekasan Regency.

The Effect of Problem Solving Method on Learning Outcomes of Elementary School Students

/in /by

This study aims to determine the difference in learning outcomes using the Problem Solving approach with classes that do not use the Problem Solving approach. This research uses quantitative approach by using quasi experimental method. This type of research is Nonequivalent Control Group Design with two groups, namely control group/class and experimental group/class. Both groups were given different treatments. The samples in this study were all Class V SDK Golo Mongkok which amounted to 40 students and were divided into two classes. Data collection techniques in the form of tests (pretest and posttest). The research instrument used is a test question.  Data analysis used is Descriptive Statistics, Data Normality Test, Variance Homogeneity Test, Statistical Hypothesis. The results showed that the average learning outcomes of the experimental class were higher than the control class. Thus it can be concluded that the application of the problem solving method can improve student learning outcomes.

The Development of Environment-Based Visual Media to Enhance Learning Outcomes and Student Motivation in Science Course

/in /by

Learning media plays a crucial role in education, especially in facilitating student understanding and motivation. In this era of rapid technological advancement, learning media has expanded to include various forms such as audio, visual, and multimedia. To enhance learning outcomes, teaching media needs to be utilized as a source of learning for students, including environmental media as a learning resource. Visual media is expected to improve students’ understanding of ecological theme concepts in line with the intended objectives. This study employs the Research and Development (RnD) method in developing learning media, requiring a suitable instructional model that aligns with the content’s characteristics. The ADDIE (Analysis – Design – Development – Implementation – Evaluation) development model is used in developing the Microsoft PowerPoint tutorial video media. Normality tests for the variables were conducted using the Kolmogorov-Smirnov test. Based on the normality test results using SPSS 15 for Windows and the Kolmogorov-Smirnov technique, the values obtained were (0.120), (0.165), (0.114), and (0.127) with significance values of (0.200), (0.092), (0.200), and (0.200) respectively. When the significance level is set at 0.05, the significance values are more significant than 0.05. Subsequently, hypothesis testing (T-test) was conducted to determine the difference in using environment-based visual media between the control and experimental groups using the t-test formula. The t-test formula was used to determine the difference in students’ critical thinking abilities, both in the SPSS 20 for Windows calculation using Separated Variance, as the data exhibited non-homogeneity of variance. The hypothesis testing results indicate that the samples are non-homogeneous, with a calculated t-value of 6.833 and a significance level 0.000. When the significance level is 0.05, the significance value is much smaller than α. Thus, it can be concluded that environment-based visual media influences students’ learning motivation in the Science subject at grade 5 of SDN Kotakulon 2 Bondowoso. Based on the calculation and data analysis, it can be inferred that the hypothesis testing results support Ha (alternative hypothesis) and reject Ho (null hypothesis), meaning there is an influence between the variable (x) of environment-based visual media development and the variable (y) of student learning motivation.
