Abstract

This research aims to describe the results of the analysis of the difficulties of class X SMK students in solving logarithm material problems. The research method used in this study is a qualitative descriptive method. The subjects of the study were 14 students of class X Nurses at SMK Kesehatan Bakti As-Syukur. The research instrument consisted of 5 logarithm material test questions. The data collection technique used in this study was in the form of test results by looking at the location of students' errors in solving questions. The data processing technique used is to calculate the percentage of student mastery of the questions with Microsoft Excel 2010 to be able to analyze student difficulties. The results of the study show that only question number 3 has a percentage of mastery of the material which is still below 72% so it can be said that most students still have difficulty in solving problem number 3 which has indicators of manipulating logarithm forms based on logarithm properties. From the results of the analysis, it can be concluded that the difficulty of class X SMK students in solving logarithm problems lies in the indicators of manipulating the logarithm form based on the properties of logarithms, namely; (1) Students have difficulty in simplifying.

Abstract

This study analyzes students' errors in doing exercises on the material of Straight-Line Equations (PGL) based on the Newman procedure. This research was conducted at one of the schools in Cianjur area, with the research subject of 12 students. The method used in this analysis is the qualitative descriptive method because it will describe the form of student errors. The data collection technique uses 5 test items. The questions were made according to the predetermined indicators of achievement of basic competencies. Furthermore, based on students' answers, the researcher analyzed the extent to the students' errors in solving PGL questions. The results showed that: (1) 50% had errors in reading problems, namely students were less careful; (2) 16.7% experienced errors in understanding the problem, namely not being able to understand (3) 66.7% experienced problem transformation errors, namely difficulties in making graphs from the instructions presented, and students did not correctly convert the information obtained into PGL graphs; (4) 50% experienced errors in process skills, namely students were not able to solve the problems and be careless in the calculation process; (5) 83.3% experienced writing errors/answer notation, namely incorrectly in writing negative signs, symbols, equals signs, not writing variables and conclusions.

Abstract

The purpose of this study is to measure the level of problem-solving ability of high school students in solving PLSV material problems. This type of research uses qualitative. The study subjects numbered four high school students in class X. The data was collected through problem tests and described using descriptive methods. The data analysis technique used consists of three paths, namely data reduction, data presentation, and drawing conclusions. Based on the polya problem solving stage, the results of the study are obtained as follows: the first stage obtains 43.75%, the second stage obtains 87.50%, the stage of non-obtaining 62.50%, and the fourth stage obtains 25%. From these results, it can be seen that the stage of re-checking is in the low category with the smallest percentage among others, while the stage of preparing a plan is in the very high category with the highest percentage.

Abstract

Interactive e-LKPD can be used as a medium for teaching materials that can identify and train digital literacy skills. Interactive E-LKPD is a two-way communication, student worksheets that can perform several activities with feedback with feedback. Social arithmetic is the subject matter studied in junior high school. The subject matter of social arithmetic provides benefits for students in solving problems of daily life, but some students have difficulty solving arithmetic problems. Therefore, this study aims to develop an interactive mathematics E-LKPD based on digital literacy. This type of R and D uses a 4D development model including “Define, Design, Development, and Desseminate”, but limitations without “Disseminate”. The results showed the feasibility of fulfilling several criteria: the validity obtained from the validation results of media experts was 99% and material experts were 95%, the results were both in the "very valid" category. Effectiveness is obtained from the results of class completeness getting 100% "very effective". And the practicality obtained from the results of student responses is 98% "very practical". Thus, the interactive mathematics E-LKPD based on digital literacy can be used as media for teaching materials for the learning process.

Abstract

The purpose of this study was to see whether there were differences in the achievement and improvement of mathematical problem-solving abilities of students who received CTL learning with students who received direct learning and to see how much influence the CTL learning model had on the mathematical problem-solving abilities of experimental class students. This study uses a quantitative approach with experimental methods. The population used was class VII students at SMP Negeri 5 Karawang Barat with samples namely class VII B (experimental class applied CTL learning model) and VII D (control class applied direct learning model) taken by purposive sampling. The instruments used are test and non-test instruments (interviews), where the data obtained will be measured by statistical tests in the form of prerequisite tests, t-tests, Mann-Whitney tests (if the data are not normally distributed), n-gain and effect tests. size. The results of this study indicate that the average achievement and improvement of mathematical problem-solving abilities of students who receive CTL learning is better than students who receive direct learning, and the large influence of the CTL learning model on students' mathematical problem-solving abilities is in the criteria classified as large.

Abstract

The purpose of this study was to determine the problem-solving abilities of junior high school students in solving mathematical problems in number pattern material. This research was conducted in one of the public schools located in Karawang Regency. There are 4 indicators of problem solving, namely, the adequacy of known and requested information data, problem solving strategies, completion of mathematical models and arguments, and re-examination of the solutions obtained. This research was conducted with a subject of 17 class VIII students with a qualitative descriptive method. The technique used in data collection was using the descriptive test method, while the technique used to analyze the data was using the average percentage. Meanwhile, the percentage of indicators (1) the stage of identifying data is 27.06%; (2) the problem solving strategy stage, amounting to 21.17%; (3) skill stage in solving mathematical models 9.41%; (4) the concluding stage of 8.23%. The results of the data analysis show that most of the mathematical problem solving abilities of junior high school students are still low.

Abstract

Research with a scientific approach in an effort to help students' mathematical understanding of grade IX SMP in transformation material has the aim of analyzing the effect of the scientific approach on students' mathematical understanding ability on transformation material (reflection). In this study, the type of classroom action research was used, with the research subjects with the criteria being students of class IX-A SMP IT Budi Luhur Cimahi. The number of samples used were 21 students for 2 cycles. The analysis was carried out with test and non-test instruments, giving questions as research test instruments consisting of 5 pre-test and post-test questions in the form of descriptions that will measure students' mathematical understanding abilities. While the non-test instrument is a questionnaire scale of 15 statements given to students to measure students' self-confidence. The data processing technique for the test instrument used is the N-Gain analysis test, while for the non-test instrument, Microsoft excel is used. The results showed that the scientific approach affected the mathematical understanding ability of class IX-A students with average criteria with a value of 0.55. The average value of the pretest is 3.86 and the average value of the posttest is 12.71. Based on these data, there was an increase in the value of 8.86, while the average value of the questionnaire was 68.41%, meaning that it had a strong effect on students' self-confidence.
