Abstract

The purpose of this research was to find out the thinking processes of a concrete student in solving two-dimensional problems. The research method used is descriptive qualitative. The research subjects were two students taken using purposive sampling. The instrument used was the Test of Logical Operations and problem-solving tests. Stages of data analysis used are researching all data, making a cognitive classification of students, choosing concrete students to be used as research subjects, reviewing the results of concrete student work in solving mathematical problems, verify data and data sources that have been classified and transcribed in the presentation or exposure of data. The results showed that at the stage of understanding the problem and re-checking the answers, concrete students use the assimilation at the stage of planning to solve the problem of doing the disequilibration. At the stage of carrying out a plan to solve a problem, concrete students carry out the accommodation. During this study, it was found that students 'habits in mathematical problem-solving did not plan to solve problems, did not re-examine answers, and there were students' habits by interpreting the final results of problems. It can be concluded that the students' concrete thinking processes in solving two-dimensional problems vary according to the stages of problem-solving.

Abstract

Mathematics is one of the basic concepts needed by students at every level of education. However, students often have difficulty in understanding mathematics. This can be seen from the mistakes made when working on math problems. Errors made by students must be addressed immediately so that no more errors occur, especially on questions that have the same characteristics. The purpose of this study was to determine the percentage of conceptual errors, arithmetical errors, writing errors and the most common mistakes made by students on the subject of exponential and logarithmic equations. Sampling was done by using purposive random sampling technique. The data in this qualitative descriptive study were collected using test, interview, and documentation techniques. The instrument used to collect data was in the form of test questions and interview guide sheets. The data were analyzed by categorizing the types of errors into conceptual errors, arithmetic errors, and writing errors and then calculating the percentage of errors in each category. The results showed that the errors made by students in each category were conceptual errors of 53%, arithmetical errors of 34.78% and writing errors of 28.99%. The error that many students make is a conceptual error as much as 53% with a moderate error percentage category.

Abstract

The Covid-19 virus spreads very quickly to various countries in the world. Various efforts have been made to break the chain of spreading the Covid-19 virus, one of which is by changing face-to-face learning methods into online learning. The obstacles that are students at the Madania Modern Yatim and Dhu'afa Islamic Boarding School Foundation (YPPMYD) during online learning are the low motivation to learn and the lack of knowledge of online learning resources. The solution to the problems offered by community service activities is training and assisting the installation of online learning application and how to use them. This service activity was carried out in a bold and attractive manner. Online it was done using the Google Meet application, while offline it was conducted at the Madania Bantul Yogyakarta Modern Yatim Islamic Boarding School Foundation (YPPMYD), which was attended by 12 students and 2 companions from students. At the end of the activity, students came to fill out a questionnaire. The results of the questionnaire showed an increase in student learning motivation by 91.07%, an increase in independence by 86.98% and an increase in knowledge of learning applications by 90%.
