Visual Basic Application for Excel is a simple program language and has the power to process data quickly. The utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel than other mathematical software are the many math functions and images available in the form of shapes or pictures. The availability of VBA, math and image functions in Microsoft Excel help teachers to design the creation of media related to mathematics learning, especially to develop the ability of junior high school students who have difficulty to connect mathematics lessons with basic mathematics knowledge requirements. By using VBA for Excel, the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 0.05. Furthermore, there is an association between the students’ self-confidence and their mathematical comprehension skills with a contingency coefficient of 0.525 including a moderate association.

This study was conducted based on observations during the implementation of learning during the covid-19 pandemic which showed the low ability of students to master SPLDV materials, considering that it requires independence in studying good self regulated learning. This research aims to analyze the influence of independence in studying science (self regulated learning) on students' mathematical reasoning abilities in SPLDV materials when learning during the covid-19 pandemic. This research was conducted by quantitative methods with a correlational approach. 15 students of class VIII at one of the junior high schools in West Bandung Regency were the subjects in this study. This research was conducted in November during the first semester of the 2021/2022 School Year. Used research instruments are about tests of mathematical reasoning skills, interview guidelines and self regulated learning opinion scales that have been adjusted to their respective indicators. Based on the test results obtained the conclusion that (1) the mathematical reasoning ability of students is influenced by independence in studying the student's self regulated learning. (2) Independence in studying the science (self regulated learning) students positively affect the mathematical reasoning ability of students. (3) The relationship between independence in self regulated learning and mathematical reasoning skills is in a very strong category.

Mathematics is closely related to real lift. However, there are still many students who make mistakes in learning mathematics, this is because students still think that learning mathematics is difficult. The purpose of this study was to analyze the students errors in solving spatial geometry problems. The subject af this research wa conducted at SMK TI Garuda Nusantara in class XII TKJ with a sample of 12 students. The method used is acase study, and the form of data collection is to provide 4 test questions on different indicators for each question. From the results of this study, the results of the highest student error were on the indicator calculating the distance between line to line with a percentage of 70,6% and the lowest student error results on the indicator calculating the angle size with a percentage of 17,2%.
