The low interest in student learning because of lack of use of media results in a lack of understanding of students. This study developed scrapbook media on thematic learning. This study was conducted to study the validity and practicality of scrapbook on Thematic learning at first class . The subject research was the student first classes of Taman Sari 01 Elementary School Pati. The research data consists of the results media validation by material experts, media experts, and responses of students' responses to the media developed. Data sources were from validator, interaction, and first grade students of Taman Sari 01 Pati Elementary School. This study used the Research and Development (R & D) research methodology and ADDIE development model. The validity of the media was obtained from media experts and material experts. Based on the results was scrapbook in thematic learning, the developed media is proven valid based on the results of media validation by experts and researchers. Learning media can also be accepted by students as evidenced by student enthusiasm and student response

The purpose of this research is to know the effectiveness of Two Stay Two Stray model assisted media of smart mathematics wheel to hail to learn fourth grader of SD Negeri Plelen 02 Batang. This research is a quantitative research using one group pretest posttest design research design. The results of the test of learning showed that the results of learning results of students who use the Two Stay Two Stray model auxiliary media mathematical wheels reach a classical percentage of 92%. The posttest score of 76.20 and the minimum completeness criterion (KKM) 70, obtained by t = 8.64 with n = 25, and ttabel 1.710. So the calculation results are known 8.64> 1.710. Based on the test criteria when obtained t count> ttable is 8.64> 1.710 so H0 diterima. In conclusion Two Stay Two Stray model auxiliary media effective mathematics media to the results of the fourth grade students of SD Negeri Plelen 02 Batang.Keywords: Two Stay Two Stray models, math smart wheels, learning outcomes

Difficulty in the calculation process. It has an impact on low mathematics learning outcomes for students. This study aims to analyze students' learning difficulties in terms of mathematical problem-solving abilities in grade III elementary school fractions. This type of research is descriptive qualitative research. The subjects taken were six students—data obtained through interviews, tests, and documentation. The instrument used to analyze the data is a questionnaire. The technique used to analyze the data is descriptive qualitative and quantitative analysis. The study results are that students have a score on the aspect of understanding the problem of 50 (33.3%) in the medium difficulty category. The planning aspect has a score of 34 (22.60%) (great difficulty). Implementing the plan has a score of 95 (63.30%) (low difficulty). The re-checking aspect has a score of 98 (65.30%), which is in the low difficulty category. The difficulty is due to the lack of understanding of the questions, errors in determining the correct strategy to solve the problems and difficulties in the calculation process, and the child's low grasping power.

The low competence of mathematical knowledge caused by the lack optimal use of the learning model makes it difficult for students to understand the learning material. The purpose of this study was to analyze the effectiveness of the Team Assisted Individualization model assisted by Ludo media on learning outcomes in terms of the problem-solving ability of fraction material. This type of research was a quantitative study using pre-experimental design in the form of a one-group pretest-posttest design. The number of samples in this study was all students of class IV, amounting to 26 students using saturated sampling type sampling. Data collection in this study was obtained through interviews, tests and documentation. The results of data analysis obtained tcount 9.698 and ttable 1.706 with a significant level of 5%. Because t_count> ttable is 9.698> 1.706, so H_0 is rejected, which means that there are differences in pretest and posttest learning outcomes. Then the two-party t-test of problem-solving abilities shows that tcount> ttable is 8,000> 1,671 then H_0 is rejected, so there is a significant difference in learning outcomes seen from the problem-solving ability using the Team Assisted Individualization model with groups that are taught with conventional models in grade IV SD. The Team Assisted Individualization model assisted by Ludo media is effectively applied in the learning process to improve student learning outcomes for fractions.
