Learning outcomes refer to the successful attainment of educational objectives by students who actively engage in the process of learning. Nevertheless, it is evident that student learning outcomes remain subpar, hence necessitating the implementation of a learning model aimed at enhancing student learning outcomes. The Group Investigation (GI) Learning Model is an educational approach that has been shown to enhance student learning results. The primary objective of this study was to assess the impact of implementing the Group Investigation (GI) Cooperative learning model and the direct learning model on the learning outcomes of eighth-grade students at SMP N 6 Tondano. Specifically, the study focused on the topic of straight-line equations. The research employed a Quasi-Experimental Design as its chosen methodology. The present study comprised two classes, namely class VIII B as the experimental group and class VIII A as the control group. The sampling methodology employed in this study was Cluster Random Sampling. The methodology employed in this study involves the utilization of written tests for the purpose of data collecting. Based on the findings of the study, the statistical analysis using the t-test yielded a t-value of 2.5709, while the critical t-value (t-table) was determined to be 2.0322. Consequently, the calculated t-value exceeded the critical t-value (t-count > t-table). This implies that the null hypothesis (H0) is rejected in favor of the alternative hypothesis (H1). Based on the findings, it can be inferred that students who were exposed to the Group Investigation (GI) cooperative learning model exhibited superior learning outcomes compared to students who were subjected to the direct learning model. This observation was made specifically in the context of studying straight-line equations among eighth-grade students at SMP Negeri 6 Tondano.

The main problem in this study is how to apply ice breaking in the learning of fifth grade students at SD Negeri Pesantunan 05, the effect of ice breaking in increasing student learning concentration and the advantages and disadvantages of ice breaking in learning. This type of research is descriptive-qualitative. Data collection techniques used are observation, interviews and documentation. The analytical method used is collecting data, data reduction, data presentation and verification. The results of this study indicate that the application of ice breaking in student learning in elementary schools can have an effect on increasing student learning concentration as long as the learning process is going well. The types of ice breaking that are often used by teachers are singing, songs and clapping which are carried out at the end of learning or on the sidelines of learning. With the application of Ice Breaking in learning can make students more active, enthusiastic about learning, and concentrating in the learning process takes place, in the application of Ice Breaking the teacher of course looks at the conditions and atmosphere of the class first whether it is possible to carry out Ice Breaking activities. We often encounter weaknesses and strengths during the process of implementing Ice breaking in mathematics learning. The advantages of implementing Ice breaking can shorten the time during the learning process, making the class atmosphere fun and cheerful. The drawback is the teacher's lack of creativity in implementing the types of ice breaking that are carried out in the classroom.

STEAM (Science, Technology, Engineering, and Mathematics) improvements in education, as well as PAUD teacher inability to effectively use the resources at their disposal despite their simplicity in the classroom. Using active and creative learning approaches, the implementation of learning in STEAM-based PAUD is designed to encourage children's creativity. The method's activities included a pre-test to gauge PAUD teachers' familiarity with the STEAM learning approach, instruction about STEAM resources after that, and training or group practice in creating STEAM-based learning resources. introducing new information, since PAUD teachers did not previously comprehend what STEAM was, They understand now it, and because it combines the five knowledges with basic tools and materials, they can develop it for use as an engaging method of instruction in the future.

The use of media becomes one of the components in learning and helps teachers to realize student-centered learning. In fact, many students at the Hassan-Savvas Reading House do not understand the material, especially fractions, because not every school uses learning media, this is also the background in doing community service. The purpose of this service is to provide assistance in learning mathematics on simple fraction material in an interesting way, namely through the media of Fractional Puzzles. The participants were 15 elementary school level children who lived around Rumoh Baca Hasan Savvas in Gampong Jambo Timu, Blang Mangat District, Lhokseumawe City. The method used is socialization, discussion, practice questions and discussion. The results of the mentoring show that in each learning the participants look happy, active and pay attention to the discussion of the Fractional Puzzle media. Participants are interested in compiling puzzles, so that it has an impact on increasing knowledge of Fractions material. Increased knowledge can be seen from the acquisition of the N-Gain value of 84% with the High criteria. The results of the assistance show an increase in knowledge of fractions through the Fractional Puzzle media

Even though blended learning requires adequate internet access, if the network is inadequate it will make it difficult for participants to take part in independent learning via online.

This research is a Classroom Action Research (PTK) consisting of 2 cycles, each consisting of 2 meetings. Before giving action, an initial ability test is first given and at the end of each cycle is given a problem-solving ability test. From the results of the analysis of initial ability test data, it was obtained that many students achieved learning completeness from the initial ability test, namely 18 out of 28 students or 21% with a grade average of 26,7. The results of data analysis in the first cycle after applying the Reciprocal Teaching type cooperative learning model showed that the number of students who achieved learning completeness was 13 out of 28 students or 61% with a grade average of 70,7. The results of data analysis at the end of cycle II with the same learning obtained the number of students achieving learning completeness, namely 24 out of 28 students or 86% with a grade average of 90,86. This means that there is an increase in students' mathematical problem-solving skills from cycle I to cycle II. Based on classical completeness criteria, this learning has reached the classical completeness target.

This study aims to analyze the use of Bloom's Taxonomy in identifying the difficulty level of questions in mathematics in elementary schools. Bloom's taxonomy is a classification framework used to classify learning objectives into six different levels, namely knowledge, understanding, application, analysis, synthesis, and evaluation. The research subjects were 15 students in class V at SDN Karet 2, Tangerang Regency. The research method used was content analysis, in which questions in mathematics textbooks for elementary schools were analyzed based on Bloom's Taxonomy categories. The data collected included the difficulty level of the questions based on Bloom's taxonomy and the distribution of the difficulty levels of the questions in mathematics textbooks. The results showed that the level of difficulty of the questions in mathematics in elementary schools varied and could be classified based on Bloom's taxonomy. Most of the items focus on levels of knowledge and understanding, with a few items testing students' abilities to apply, analyze, synthesize, and evaluate mathematical concepts. This shows that there is a tendency to emphasize understanding concepts rather than applying concepts in learning mathematics in elementary schools.
