Abstract

This study aims to determine the effect of applying the Learning Cycle 5E model assisted by Macromedia Flash media on the understanding of quadrilateral concepts by seventh-grade students at SMP Islam Alfalah Abung Tinggi. This research uses a quasi-experimental design with the Nonequivalent Control Group Design method. The sample consists of two classes, with the experimental class taught using the Learning Cycle 5E model assisted by Macromedia Flash, and the control class taught using traditional learning models with PowerPoint. Data were collected using a validated descriptive test and analyzed using t-test to examine the differences between pretest and posttest scores. The analysis results show a significant effect of the Learning Cycle 5E model assisted by Macromedia Flash on improving students' concept understanding, with a t-value = 2.863 > t-table = 1.671, indicating that the alternative hypothesis is accepted, and the null hypothesis is rejected. This finding contributes to the development of mathematics education, specifically in enhancing the understanding of quadrilateral concepts through more interactive and engaging teaching methods.

Abstract

The fact of the problem of low critical thinking skills of students is 65.49% in accordance with the provisions of the KKM which is 70. In addition, from the results of observations obtained students are less able to analyze ideas to solve a problem. In addition, students are reluctant to do practice questions that would enable students to be competent in determining strategies and conclusions in solving questions. One of the models indicated as being able to overcome the problem of low critical thinking skills in statistical material is the TPS Model. The study aims to determine whether there is an effect of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi, North Lampung in the 2023/2024 Academic Year. This research method is quantitative experimental with a quasi-experimental design. The form of quasi-experimental chosen is nonequivalent control group design. Then samples were taken from two classes, namely one class VII D for the experimental class using the TPS model and one class VII C using the model commonly used by teachers. The results of data analysis using the t-test, obtained tcount = 3.102 and ttable 1.990 then tcount> ttable so that H0 is rejected, and Ha is accepted. This means that there is an influence of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi

Abstract

Public speaking is an essential part of communication skills that are not easily mastered by everyone. Anxiety about speaking in public often hinders individuals from developing. The negative impacts can be seen from the physical and emotional health disorders they experience. Lack of confidence when speaking in public is also experienced by students of MAN 2 North Lampung. The right solution is to hold public speaking training that can build students' confidence in speaking in public. The approach is a sequence of training sessions that are precisely and clearly organized within a given time period, tailored to the organizer's time and location available. The activity's outcomes demonstrate that a large number of high school students are interested in public speaking, and we can observe that each student has good potential when it comes to public speaking practice. The inference that may be made is that public speaking abilities are fundamental and should be had by everyone, particularly high school pupils who will find them valuable in the future.

Abstract

The low the skill level eight grade students at MTs Negeri 1 North Lampung to understand the concept of linear equations result from the implementation of learning models. The learning model that is tought to influence the understanding of the concept of linear equations is the Desmos-assisted Discovery Learning learning model. Its purpose is in the present research was to identify if the Desmos-assisted Discovery Learning model impacts student’s understanding of the concept of linear equations among eighth-grade students at MTs Negeri 1 Lampung Utara. This study applied a Quasi-Experimental Design featuring a Nonequivalent Control Group Design. The population involved in this research consisted of all eighth-grade students at MTs Negeri 1North Lampung.

Abstract

The Linear Programming course, specifically the Transportation Problem topic, is often considered difficult by mathematics education students due to the dense mathematical modeling and procedural algorithms that trigger learning anxiety. This research is driven by the need to address passive classroom dynamics and student heterogeneity through adaptive learning, a method whose implementation is challenging for a lecturer to do alone. This study aims to describe the dynamics of implementing Lesson Study for Learning Community (LSLC) based on an adaptive learning approach to the linear programming transportation problem. A qualitative descriptive methodology was used to capture critical moments in the classroom, dissect thinking obstacles, and document lecturer collaboration. This study focuses on in-depth qualitative observation through data reduction, data display, and triangulation. The findings show that the Plan stage successfully designed an adaptive learning path that integrates sharing tasks (Northwest Corner method) and jumping tasks (VAM with dummy). During the Do stage, this approach effectively activated a caring community, namely refutation followed by constructive feedback. Additionally, students cross-checked directly with the model lecturer to visualize the distribution route flowchart to resolve their bottlenecks. The See stage confirmed that this intervention triggered the active participation of passive students, and identified that minor computational errors were caused by inaccuracies in reading demand capacities. In conclusion, the integration of LSLC and adaptive learning provides an optimal evidence-based ecosystem to accommodate diverse student learning rhythms while continuously improving the quality of mathematics learning
