Abstract

This study aims to describe students' algebraic thinking in solving number guessing problems using Microsoft Excel. In human life, algebraic thinking plays a very important role. Many problems in human life can be solved with algebraic thinking. In solving mathematical problems, Microsoft Excel can be used to assist students in solving mathematical problems. The method used in this study is qualitative, involving junior high school students as research subjects. The subjects are divided into two categories: the first category consists of students with correct mathematical modeling and correct Microsoft Excel formulas, and the second category consists of students with correct mathematical modeling but incorrect Microsoft Excel formulas. Data were collected through analysis of students' work completed using Microsoft Excel and interviews. he results of the study show that the difference in students' algebraic thinking between those with correct formulas and those with incorrect Microsoft Excel formulas is evident in the processes of organization, analytical thinking, and generalization. Students with correct Microsoft Excel formulas can solve equations easily, while students with incorrect Microsoft Excel formulas solve equations without paying attention to the order of operations. In the generalization process, students with correct Microsoft Excel formulas create formulas without the aid of solving equations, whereas students with incorrect Microsoft Excel formulas create formulas by combining operations in solving equations. The formulas created do not use parentheses, causing the Microsoft Excel system to perform multiplication and division operations first. These findings suggest that when using Microsoft Excel in lessons, attention should be paid to the use of punctuation marks that can affect the order of operations in the Microsoft Excel system.

Abstract

Students need to be equipped with skills to compete globally through context-based learning. Context helps them connect math to the real world, so suitable context-based tasks can strengthen their understanding. However, the tasks designed by prospective teachers often lack of authenticity. In addition, textbooks are still lacking in presenting context-based tasks, while teachers tend to think of them as ordinary word problems. Therefore, teachers need to be given additional insights in designing context-based tasks collaboratively through community service activities for teachers. The teachers actively participated in the workshop and they felt that the workshop materials were useful for classroom learning.

Abstract

Reasoning and proof are part of mathematical activities. One of the activities of reasoning and proof is constructing conjectures. In several studies, students' skills in constructing conjectures are still lacking. Conjecture construction can be maximized through collaborative discussions. Geogebra helps students in visualization, construction, and discovery of concepts. This study aims to describe students' conjecture construction collaboratively assisted by Geogebra on the topic of. This study is a qualitative descriptive study. Data were obtained through assignments and interviews. The subjects in this study were 4 groups divided into high homogeneity, medium homogeneity, low homogeneity, and heterogeneity groups. Conjecture construction was analyzed based on the stages of (1) understanding the problem, (2) exploring the problem, (3) formulating conjectures, (4) justifying conjectures, and (5) proving conjectures. The result showed t the stage of understanding the problem, all groups can determine what is requested and what is given even though there are still errors. At the problem exploration stage, all groups illustrate problems on Geogebra, they also explore using tools on Geogebra the group is highly homogeneous and is having discussions in exploring problems At the stage of designing the conjecture, they discussed with their group to create a conjecture from the exploration results, but the low homogeneity and heterogeneous groups prepared the conjecture without discussion. All groups can explain the reasons for the conjectures that have been made. At the stage of proving the conjecture, only highly homogeneous and moderately homogeneous groups allow the conjecture. At the stage of proving the conjecture, their proof structure was incomplete, they only described one example of the conjecture they made.

Abstract

Mathematical modelling plays an important role in developing students' problem-solving skills and addressing real-world contexts. Due to the complex nature of mathematical modelling, working collaboratively plays an important role. Working collaboratively is also able to provide better results than working individually. This study is descriptive qualitative research that aims to describe the collaborative mathematical modelling process of junior high school students on linear function material. The subjects of this study were 3 groups where the first group used a linear function model and did two modelling cycles, the second group used a linear function model and did one modelling cycle, and the third group used a division and mean value model. Students are able to identify problems until assumptions are made. Based on these assumptions, students can carry out further stages of modelling collaboratively until the validation stage. However, some groups still experienced errors in identifying the problem so that the assumptions did not match the context of the problem which caused one group to do two cycles of mathematical modelling. Students who are active in mathematical modelling are high and middle ability students, while low ability students are less active in following the mathematical modelling sequence.

Abstract

Representation translation is the ability to change one form of representation to another. This research aims to describe the failure of the translation of verbal to symbolic representations in solving contextual problems in male and female students. The research partisipant were eight students of class VII an Islamic public school at Gresik. The data collection technique is through task-based interviews. The data on the translation of verbal to symbolic representations were analyzed by unpacking the source, preliminary coordinator, constructing the target, and determining equivalence. The results showed that at the stage of unpacking the source, both male and female students experienced the same failure, namely not understanding more complex contextual problems. In the preliminary coordinator stage, male students failed to understand the requested symbolic representation, understand the meaning of mathematical symbols, and determine keywords, while female students only failed due to their mistakes in the previous stage. In the constructing the target stage, male students failed to construct a symbolic representation of the plans made and translate into mathematical symbols, while female students failed to translate verbal words into mathematical symbols and mathematical operations. At the determining equivalence stage, male and female students have not been able to do it.

Abstract

This study aims to analyze the planning process for solving contextual problems. The research subjects consisted of three students of class IX SMP. The research used is a qualitative research with a descriptive approach. The instrument used is a task-based interview. The data is analyzed according to the indicators of problem solving at the planning stage, namely identifying information, selecting old knowledge that can be used in problem solving, mentioning theorems related to the problem, making plans. The results showed that the first student was able to identify the information needed but the student did not submit it in writing. The first student solved the problem using the volume formula, but the student experienced a conceptual error in the middle of completion. The second student is able to identify and write down the required information, the second student uses mathematical formulas and estimates to determine the amount of wrapping paper needed. The third student is able to understand which information can be used and which information is redundant. At first the third student used the formula to solve the problem, but in the middle of the completion the student changed the plan by applying real life/context applications. Based on the results of research conducted that two students out of three students when solving problems did not pay attention to the context.

Abstract: Students' Conjectures on Open Classical Analogy Problem: Expanding or Narrowing?. Objectives: This study aims to describe students' mathematical conjecture in the context of open classical analogy problem. Methods: This descriptive research describes students' conjectural profiles using open classical analogies. Data were collected from the responses of 68 students. Data analyzed using constructor example, process, and quality of the conjecture. Findings: Results show that the example of constructing the conjecture has not paid attention to all possible cases, while the process of the conjecture used by students was from simple to more expanding or narrowing. Some of the proposed conjecture quality does not include the necessary constraints, and some include unnecessary limitations. Students can add to statements that sharpen the conjecture proposed previously. Conclusion: The results of this study indicate that in the construction of conjectures in the context of an open classical analogy, students involve their critical thinking skills. Keywords: conjecture, example, open classical analogy, process, quality of conjecture.DOI: http://dx.doi.org/10.23960/jpp.v14.i1.202419

Abstract

Mathematics education is looking for innovative methods to foster problem-solving skills in students. This research develops a problem-solving assessment using GeoGebra Classroom, a versatile interactive mathematics software, to revolutionize mathematics formative assessment and improve students' problem-solving skills. This study adopted the analysis, design, development, implementation, and evaluation (ADDIE) instructional design model stages. The design stage created a comprehensive assessment blueprint, incorporating GeoGebra Classroom functions to create interactive problem-solving tasks. Data analysis used both quantitative and qualitative approaches. Qualitative data consisted of feedback and suggestions from assessment experts, mathematicians, and GeoGebra specialists. Meanwhile, quantitative data included expert scores and cognitive tests that measured students' problem-solving abilities. A cognitive post-test was conducted to measure the progress of students' understanding while using the assessment product. The results of the content validity analysis, assessed using Aiken's V, ranged from 0.85 to 0.92, indicating a high level of validity for the problem-solving skills assessment in terms of content and construction. Some revisions were made to the design of the developed media to make it more interactive for students. These findings suggest that we can further use problem-solving questions integrated with GeoGebra Classroom to uncover the problem-solving skills of junior high school students.
