Abstract

In accordance with the problem limitation, the objective in this study is to find out the percentage of errors made by students in solving mathematical problems in the algebraic function limit material. Descriptive research with a qualitative type approach used in this study. One high school in West Bandung regency, Darul Falah High School, is the subject of this study. A diagnostic test was given in the form of a matter description of the algebraic function limit to 21 students as a sample. The object to be reviewed is an error made by the student in solving the problem. The type of error is taken from the classification written by Herman Hudoyo, namely there are concept errors, procedural errors, and operating errors. From the results obtained, the percentage of student errors in completing mathematical problems material limits on algebraic functions in the concept type by 34.5% is categorized high enough for the type of procedure to get 36.9% categorized quite high while the type of operation by 61.9% is categorized very low. This indicates, students still have difficulty in operating a number, especially in numbers with positive and negative signs. Inaccurate and lack of understanding of students is the cause of errors that arise so that there is a need for follow-up to overcome these errors so that similar errors do not occur.

Abstract

This study aims to determine the motivation to learn mathematics students after learning to use media for VBA Excel. The research was carried out in Mts Nurul Hidayah with the number of subjects being 25 students of grade 8A. The focus on what will be studied is the students' motivation to learn mathematics, with 50% positive statements and 50% negative statements presented which are adjusted to the indicators of mathematics learning motivation. Descriptive research with a qualitative approach used to achieve research objectives. 20 statements representing 6 indicators were given to students by given answer choices, namely strongly agree, agree, disagree, and disagree. Data analysis was carried out by giving points to each student's choice, then accumulating to get the final results and adjusting the categories including whether or not students' motivation to learn mathematics after learning using VBA for Excel. From the data tabulation results obtained an average of each indicator of learning motivation is 81.29%. In accordance with the large classification percent is in the very good category. So it can be said that students' motivation to learn mathematics is very good after learning to use media for VBA Excel.
