Abstract

Reflective abstraction really helps students in the learning process of mathematics. Students who have good Reflective Abstraction will understand mathematical concepts and can relate mathematical concepts easily. This research question is how is each level of the reflective abstraction of high school students? This research was conducted using a qualitative approach with grounded theory methods. The research subjects involved in this study were allegedly 36 people who came from senior high schools in Pangkalpinang, Bangka Belitung Islands Province. Of the 36 subjects, 8 people were selected consisting of two representatives from each level of Reflective Abstraction for further interviews. This study found that the attribute Level 4 which is Building the Right Clear Concept is to build a new concept without experiencing errors in the concept being built, the concept that is built clearly and easily fits, and Explanatory Arguments which provide arguments or explanations for each step of the concept being built. Level 3 which is Building a Concept that contains a Complete Concept Clear or there is a Concept Mistake is building a new complete and clear concept or building a concept but there is an error in the concept being built, and Level 2 which does not build a concept is unable to build a new concept but remembering Returning a relevant concept, which means being able to remember related concepts but unable to link relevant concepts or being unable to recall relevant concepts so being unable to construct new concepts

Abstract

This research is driven by the low of student’s critical thinking ability in learning Mathematics as well as teachers that still use conventional models during teaching and learning activities. This research aims to determine the effect of the Means Ends Analysis (MEA) learning model on students' critical thinking ability. The quasi-experimental method is used in this research along with a quantitative approach. The research design uses a non-equivalent control group pre-test post-test design. This research applied the MEA learning model to the experimental class and the conventional model to the control class. The population in this study was the fifth-grade students at one of the Pangkalpinang State Elementary Schools. Purposive sampling is used as the sampling technique. The samples in this research were Class V-A as the experimental and Class V-B as the control class. The data collection technique uses a critical thinking ability test in the form of essay questions consisting of a pre-test and a post-test. The data analysis technique in this research uses the normality test (Kolmogorov Smirnov test), homogeneity test (Fisher test), and hypothesis test which uses the dependent sample t-test (pooled variance). Based on the results of the hypothesis test using the dependent sample t-test (pooled variance), the value of tcount = 5,185 > ttable = 1,995. So, it can be concluded that Ha is accepted; it means that there is an influence of the MEA learning model on students' critical thinking ability in class V on fraction topic.

Abstract

This study was conducted to determine the characteristics of LKPD using the context of Bangka Belitung’s local cuisine on a valid and practical system of linear equation in three variables, and to determine the potential effects in training mathematical literacy skills. This study uses the Development (R&D) method with the ADDIE model by Branch. The subjects of the study were the students of class X DKV1 which were divided into a group of 3 students in one-to-one stage, 6 students in small group, a group of 17 students in field test; while there were 20 students as implementation subjects of class X DKV2. The data analysis techniques are the descriptive qualitative and descriptive quantitative. This study developed a very valid LKPD on the material criteria with a percentage of 87%, 88.6% in media criteria, and 75% valid in the language category. The developed LKPD is also very practical with a percentage of 82.4%, and this LKPD has characteristics in accordance with mathematical literacy, contains the context of Bangka Belitung’s local cuisine and contains the system of linear equation in three variables. The potential effect of LKPD in training students' mathematical literacy skills is 56.00% with a Fairly High category.

Abstract

This research is motivated by the limitations of teachers who have not implemented teaching materials in schools, the lack of mathematics word problems related to everyday life issues, and using conventional methods in class resulting in low students' problem-solving abilities. This study was conducted to determine the characteristics of mathematics e-modules based on problem-based learning using the flip pdf professional application on valid and practical Matrix and to determine its potential effects. This research is a research and development with a 4D (four D) development model consisting of four stages, they are Define, Design, Develop, and Disseminate. This study develops a mathematics e-module based on problem-based learning using the flip pdf professional application on valid matrix with an average validity score of 98.89% including the criteria of "very valid" and practical with an average practicality score of 89.03% including the criteria of "very practical. The characteristics developed are the existence of questions related to the competency of the department and the stages of work using the steps of the problem-based learning model. E-modules also have a potential effect of 0.74 on students' problem-solving abilities, which can potentially improve understanding and problem-solving abilities in mathematics.
