Abstract

This study aims to describe the validation process in the mathematical modeling of male and female students. The subjects of this study were male and female students at State Junior High Schools in Surabaya. Data collection procedures through the assignment of mathematical modeling problems and interviews. Data analysis refers to the validation typology of Czocher (2018). The results show that male students and female students have similarities in validating mathematical solutions obtained by repeating arithmetic operations performed previously. In addition, the two students equally succeeded in validating the real result found with consideration related to the effect of changing situation model and arithmetic operations. However, male and female students failed to generate a variety of models so that no activity emerged in generalizing the various solutions obtained. Male students are able to consider the influence of real context aspects on the solutions found, while female students are not. Female students can explain the real model that was built by mentioning the specified mathematical concepts and the reasons for using them, while male students are not.

Abstract

The process of knowledge construction can provide meaningful learning experiences for students. This is because students build new knowledge themselves by connecting one knowledge to another. The purpose of this qualitative research is to describe the process of new procedure’s construction using analogy. The subjects of the research consisted of three students of grade X high school (one student took the test individually, two students took the test in pair). Data analysis based on the APOS theory’s stage (Action, Process, Object, and Schema). At the action stage, both individual and paired students determine what is known and asked about the system of linear equations (SLE) in three variables problem based on analogy with the known things and asked about the SLE in two variables problem. They correctly determine the solution set of SLE in three variables. They also checked the correctness of the solution set of SLE in three variables correctly. At the process stage, they outline the steps of defining the solution set of SLE in three variables clearly. At the object stage, individual student cannot explain other methods of solving SLE in three variables, while paired students explain four other methods of solving SLE in three variables, that is the method of elimination, substitution, graphing, and matrix. At the schema stage, individual student cannot generalize some methods of solving SLE in three variables, whereas paired student generalize some methods of solving SLE in three variables. They also concluded the most effective method of solving SLE in three variables, that is the combined method. Individual student also explains that there is a SLE in three variables that has no solution, whereas paired students cannot explain it. They can construct new procedure well, despite errors in their process. In the process of new knowledge construction, the student's prior knowledge determines the quality of its construction process.

Abstract

This study describes the development of learning media based on ICT using game-based learning methods in statistical material and the results of its development are viewed from the criteria of the eligibility quality of the media. This research refers to the ADDIE Lee & Owens development model which consists of 5 stages, namely at the analysis stage, needs assessment and front-end analysis are carried out, the design stage is determining statistical material, navigation, flowcharts, and storyboards, the development stage is the process of making media and instrument validation ( validation sheet, pre-test, post-test and user response questionnaire) by two media experts and two material experts, the implementation stage was carried out by field trials on six class X students of a private high school in Sidoarjo, and the evaluation stage consisted of 3 levels, namely level 1 reactions, level 2 knowledge, and level 3 results. At this stage an assessment of the validation results was carried out from the media expert validator with 79.63% results in the appropriate category and material experts with 80.83% results in the appropriate category as an evaluation of level 2 knowledge, then an assessment of the results of the student respondent's questionnaire as an evaluation of level 1 reactions with a result of 80 .75% is in the proper category and the assessment level 3 results, obtained from the results of the pre-test and post-test. After that, the average rating of each aspect was added up from all validator assessments and student response questionnaires to determine the quality of the resulting media, which was 80.16%, according to quality criteria, categorized as feasible.

Abstract

Analogy helps students find solutions to problems that involve new knowledge by referring to previously learned knowledge. Analogical argumentation plays a crucial role in supporting solutions to interconnected problems. Analogical argumentation itself is defined as the process of analyzing information from two similar and interconnected problems to provide logical reasons to justify conclusions. This research aims to describe the analogical argumentation of high school students on predictive analogy problems. This study uses a descriptive qualitative approach. The research subjects are three 10th-grade students from a public high school in Bojonegoro, selected based on the criteria of the source problem 1) claim being supported by grounds and warrant, 2) claim being supported by grounds, warrants focusing on congruence, and backing, 3) claim being supported by grounds, warrants focusing on square rotation, and backing. The data from the analogical argumentaion task and interviews were analyzed using predefined indicators by the researcher. The research findings indicate that students' analogical argumentation begins with identifying information, questions, and identical concepts between the two problems. Then, students make assumptions about the structure of the target problem in relation to the source problem, search for similarities in geometric properties, and discover relationships between the questions in both problems. Students engage in appropriate argumentation based on the source problem to predict conclusions for the target problem. They construct grounds and warrants based on the structure of analogical argumentation. Students tend not to double-check their answers because they are already confident with their stated conclusions.

Abstract

Analogical reasoning is a process of identifying two problems that aim to produce knowledge by associating relevant concepts and facts and adapting them so that they can solve more complex problems. Low surface similarity does not play a significant role in solving analogical reasoning. This type of research was carried out descriptively with qualitative methods with the aim of describing students' reasoning in solving analogy problems with low surface similarity. The research was conducted at one of the junior high schools in Sidoarjo with three selected students. Research data were analyzed using indicators that had been made by researchers. The data from the research results gave rise to three students who have uniqueness in analogical reasoning. There are two peculiarities found, namely the peculiarities with general cases and the peculiarities with special cases. The low surface similarity in analogy problems has an impact on students in the form of different stages of analogical reasoning that are passed by the three students. Students with general characteristics have stages of linear analogy reasoning. Students with special case characteristics have dynamic analogical reasoning stages. Identifying is done by students by identifying characteristics and concluding the relationship between the two problems. Mapping is done by students by mapping information related to analogy problems. At the time of applying the answers to the source problem to the target problem, there were two students with special characteristics who returned to the previous stage because they found it difficult. Verifying has been done by each student, but students with special cases have beliefs that are contrary to the results of the answers. So, the use of source problems and target problems that have low surface similarities can be used with the condition that the structure of the answers between the two problems must be analogous to each other.
