Abstract

Mathematical proof is a series of logical statements, where one statement implies another, which will provide an explanation of the truth of a statement. In mathematical proof, there are several mistakes that students or students often make when solving problems. The aim of this research is to find out the types of students’ or students’ errors in mathematical proof. This research is a systematic review research, which was carried out by comparing and analyzing articles taken from digital databases such as Springer Link and Semanthic Schoolar. Articles that have been searched for with specified keywords are then excluded according to the specified parameters, so that several reference articles are obtained. The research results show that the types of students’ or students’ errors in mathematical proof are as follows: (1) Conceptual errors with indicators, namely errors in understanding and recognizing commands or symbols in the problem. (2) Principle errors with indicators, namely errors in determining the problem solving strategy or theorem in the problem. (3) Operational errors with indicators, namely errors in algebra operations and problem solving procedures as well as errors in completing proofs correctly.

Abstract

Thinking is a way of thinking that involves discussing problems and solutions so that these solutions can be represented in a form that can be completed by someone in processing information. HOTS (High Order Thinking Skill) is closely related to computational thinking skills. This research aims to analyze students’ computational thinking abilities using Geogebra mathematics software. This research is a systematic literature review, in this research the author analyzes and compares several articles obtained from the internet or digital databases, for example Semantic Scholar or Springer Link. The articles that have been found are then selected according to the title researched, so that we get several reference articles. The research results show that the use of Geogebra mathematics software in learning has a great influence on students’ computational thinking abilities. Geogebra is a media with a visual, analytical and numerical approach that can be solved using algorithms that require computational thinking skills to operate. There are five aspects of thinking skills that are in line with mathematics learning based on students’ reasoning abilities, problem solving abilities, critical thinking abilities, and mathematical representation abilities. These five aspects are: (1) Decomposition (decomposing complex problems into simple ones), (2) Pattern recognition (creating and identifying problem patterns), (3) Abstraction (finding concepts that you want to apply to problems), (4) Algorithms (developing solution or algorithm), and (5) Evaluation (analyzing each error).

Abstract

Ethnomathematics is one of the approaches that integrates local wisdom with mathematics learning. This study aims to develop PBL-based LKPD with ethnomathematics nuances at the Maimun Palace. This research method is research and development (Research and Development). The development model used as the basis for this study is the ADDIE development model (Analysis, Design, Development, Implementation and Evaluation). The results of the study showed that the LKPD developed was included in the valid category, for the average overall result of the LKPD validation assessment from the three validators was 4.35. In the implementation, the response of students to the LKPD with an average score of 4.48 was categorized as very good and met the practicality of the LKPD, so it did not need to be revised again. The PBL-based LKPD with ethnomathematics nuances produced, along with its supporting instruments, have met the criteria of validity, practicality, and effectiveness.
