This study aimed to develop a set of PISA-like mathematics problems on uncertainty and data content using football as a context which was valid, practical and had potential effects on students’ mathematical literacy ability. The method used in this study is design research with development studies type which had two stage: the preliminary and formative evaluation. Tenth-grade students of senior high schools in Palembang were involved in this research. This study produced a set of PISA-like mathematics problems at 3, 4, and 5 level. In this case, student’s strategies used some ability in solving one of the problems, namely mathematizing, representation, and communication ability. There were 16 out of 35 students using mathematizing and communication ability, 10 out of 35 students using representation and communication ability, and 9 out of 35 students only using communication ability. Also, the results of the interview with some students showed that they liked to do such PISA-like mathematics problems because they could improve their literacy ability in solving the PISA-like problem.

Project-based learning (PjBL) is an appropriate learning model that can shape students’ scientific, social and higher-order thinking. Implementing PjBL in education gives students the freedom to plan their own learning activities, conduct projects collaboratively and produce products. In a healthy menu project, PjBL can help students calculate their excess weight. The purpose of this study was thus to design a healthy menu that assists Indonesian junior high school students solve numeracy problems using obesity context. The method followed a design research type validation studies using observation and document reviews as data collection techniques. This study produced a learning trajectory that can help grade VII students solve arithmetic operations using obesity context through two activities. In the first, the students were asked to record their respective heights and weights, then use them to determine their body mass index (BMI) and body mass ratio (BMR). Then, the students confirmed their necessary daily caloric intake, and categorized their BMI and BMR results as underweight, normal, overweight or obese. In the second activity, the students developed healthy menus per their respective tastes based on their weight categories from the first activity. The study concluded with the students successfully producing healthy menus that they designed according to their calculated required daily caloric intake.

This study aims to improve the skills of retelling fables through the PBL (Problem Based Learning) model for 2nd grade students at Muhammadiyah 4 Batu Elementary School. This type of research is Classroom Action Research (CAR). The object of this research is the implementation of the process and the results obtained from the application of the PBL model to the skills of retelling fables. Data collection methods are observation and performance tests. The data analysis technique used is descriptive qualitative. Based on the results of data analysis, the highest score obtained by students was 92. students who got the highest score were 6 children. The lowest score is 4 children. With details of 24 students have reached the minimum completeness criteria.
