PISA is an international assessment of mathematics and science achievement that concern for the mathematical literacy. Students’ mathematical literacy, however, was still low in Indonesia. This study aims to develop PISA-like problem that valid, practical and has potential effect to assess mathematical literacy. This study was research and development that consisting of preliminary, development, and assessment stages. The subject of this research was students on grade 7th. The data was collected by observation, questionnaire, and test. This research result PISA-like problem involves three questions with Batik theme in quantity content. This PISAlike problem was declared valid, practical, and had a potential effect to assess mathematical literacy. This problem is valid based on judgment from experts concerning on the content, construct, and language aspects. This problem is practical based on the results of the test to small groups of students. Besides, this problem has potential effect on assessing students’ mathematical literacy.

During a pandemic like this, they were growing new regulations for conducting online learning, causing further problems in decreasing student learning outcomes in changing learning systems. This study aims to determine the factors that influence student learning interest in online learning with the Discord application, how the use of the Discord application is used in science learning and the effect of the Discord application on student learning outcomes in science learning. This research is a quantitative quasi-experimental study with a pretest-posttest control group design. The number of samples was 64 students from classes 7A and 7B, SMP Negeri 1 Depok, Depok District, Cirebon Regency. Data were obtained through pretest, posttest, questionnaire, interview, and documentation study. The results showed that the attractiveness of the Discord application as an online learning medium could influence students' interest in learning. The connectivity between teachers and students was more effective and efficient in online learning using the Discord application. The opportunity for students to play an active role during the learning process is incredible. The encouragement of motivation through the attitude of the teacher in learning. The influence of online learning media in the form of the Discord application on student learning outcomes in science subjects.
