This study aims to obtain an overview of the characteristics and levels of metacognitive ability of junior high school students as seen from the melancholic and choleric personality types according to Hippocrates-Galenus. The results of this study are expected to be used as consideration for teachers in designing mathematics lessons that pay attention to personality types and students' metacognitive processes. A qualitative descriptive approach was chosen to answer the research objectives. At the same time, the research subjects were two grade VII students with melancholic and choleric personality types in one of the Muhammadiyah Junior High Schools in Jepara. The purposive sampling technique used in this research to subject selection. Data collection techniques used personality type questionnaires, metacognition tests, and interviews. Data analysis used three steps, namely data reduction, data presentation and conclusion drawing. The results showed that melancholic and choleric students had different characteristics and levels of metacognition. Melancholic students are at the metacognitive level between tacit use and aware use, while the rest of the cholerics are at the tacit use metacognition level.

The pandemic of COVID-19 has forced the teachers and students to hold the teaching and learning remotely. All the process of learning was conducted online via various mobile applications. Students widely use smartphones as a medium to receive learning materials, join online classes, and study. However, it was questioned whether students are engaged with their reading materials when they have to read the texts on screen or digitally and learn from them. It is expected that the use of digital devices has influenced students' reading engagement, especially when the reading is to learn. This study aims to find out about the students' engagement in reading digital texts during online learning. The study collects the data from self-report questionnaires, interviews, and observation. The result shows that students do not experience behavioral and affective engagement as well as a negative response while they are reading the texts onscreen during online learning.

This study aims to analyze the differences and also the relationship between attitudes and self-efficacy of students in science lessons. This research is important because in science lessons the teacher must know the attitudes and self-efficacy of students because they affect the learning process. This type of research is quantitative with comparative type. The number of respondents used as a sample is 74 students. The data collection technique used simple random sampling. The results of the study using the T test were that there were significant differences in the attitudes and self-efficacy of students in science lessons, both female students and male students. The results of the correlation test between students' attitudes and self-efficacy towards science subjects in grade 8A showed that the two variables (attitude and self-efficacy) were related. And the results of the correlation test in class 8B showed that the two variables (attitude and self-efficacy) were related. The urgency of this research is that teachers can find out the differences in attitudes and self-efficacy between male and female students. The novelty of this research compared to previous research is that it uses Attitude and self-efficacy variables, with different indicators from previous research.

Learning media in Mathematics by using Microsoft Excel software that assisted Visual Basic application is a tool that can be applied for a more interactive visualization so that students better understand about mathematical concepts. Microsoft Excel is a software that serves to process data in the form of numbers that are always associated with mathematical commands. In addition, the functions of commands in Microsoft Excel can be applied in various fields such as Statistics, Economics and Finance, Mathematical Logic, and Engineering. If using mathematical concepts with data processing. But it is not just a number, it can also be used to process objects on shapes or drawings on images. This, of course, requires a function other than the mathematical functions of Visual Basic Applications, which can make math tools more interesting. The advantages of Microsoft Excel with Visual Basic for Application (VBA) are (1) the images are more interactive with different sizes and can make more; (2) more economical; (3)saving time; (4)the software is easy to find, and (5)improving students 'understanding of mathematical concepts and foster students' sense of trust, especially in junior high school students.
