Abstract

Mathematical literacy is defined as the ability possessed by an individual in formulating, employing, and interpreting mathematics in a variety of contexts. This research aims to describe the mathematical literacy processes of Junior High School students in solving PISA-like problems on space and shape content. The method in this research used qualitative descriptive. The research subject was students of the ninth grade in SMP Negeri 2 Krembung on Sidoarjo, which consisted of twenty-nine students. The instruments used were test and interview. The results showed that the students’ mathematical literacy was classified as less for the process of formulating. Some students still find many difficulties, such as difficulty in determining the strategy used in solving the problem as well as errors in calculation and drawing conclusion. The students’ mathematical literacy was classified as quite good for the process of employing. Students understand the intent of the problem and know what strategy used, although there were some minor errors in calculation or drawing a conclusion. The students’ mathematical literacy was classified as very lacking in the process of interpreting. Students only guess because students were still unable to understand the meaning of the questions and what strategies were used to solve the given problems to answer questions.

Abstract

This study aims to develop interactive learning media based on PowerPoint VBA on a system of two-variable linear equations and determine the results of the development of learning media in terms of validity, practicality, and effectiveness. This research uses the ADDIE development model. The instruments used included media validation sheets for media experts, media validation sheets for material experts, pretest-posttest sheets, student and teacher observation sheets, and user response questionnaire sheets. Based on the results of the research that has been done, an average validity value of 3.08 (media expert) and 3.29 (material expert) is obtained so that it can be categorized that PowerPoint VBA-based interactive learning media is valid. This learning media trial was conducted on a limited basis to 25 class VII students of SMP Negeri 1 Dlanggu to obtain data from practicality (student observation sheets, teacher observation sheets, and user response questionnaires) and media effectiveness (pretest and posttest). The results of the study after being tested and evaluated, that this learning media is said to be practical because based on the percentage of user response questionnaires obtained 75.75% or it can be used without revision and based on student and teacher observation sheets each obtained a very good category with a percentage of 93.68 % and 78.57%. Based on the pretest and posttest with an N-Gain value of 0.37, it can be said that this PowerPoint VBA-based interactive learning media is effective in the moderate category.

Abstract

In the current technological era, the use of technology is important in the world of education.Trends in Mathematics and Science Study (TIMSS) 2019 showcases the importance of using learning technology to increase the effectiveness of learning and teaching. Educators need to make adjustments to develop the quality of learning by using technological media in learning. One of them is by using a smartphone. Thus it is necessary to develop media-based learningsmartphone. The purpose of this research is to find out the process and results of the development of instructional media "Plus And Minus” in terms of validity, practicality, and effectiveness. This research is a development research using the ADDIE model which consists of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. The instruments used include media validation sheets for media experts, media validation sheets for material experts, student response questionnaire sheets and learning achievement test sheets. Based on the results of the research that has been done, an average validity value of 3.12 (media expert) and 2.78 (material expert) is obtained so that it can be categorized as learning media "Plus And Minusthis is valid. This learning media trial was conducted on a limited basis to 30 class VII-A students of SMP Negeri 1 Mojowarno to obtain data from practicality (student response questionnaires) and media effectiveness (learning achievement score sheets). The results of the research after being tested and evaluated, that learning media is declared practical with a good category gets a score of 3.02 or a percentage of 75.5%. Effective criteria are obtained from the results of the learning outcomes test scores. Learning media is declared effective with a good category with a percentage value of 60.46667%.
