Learning can be achieved optimally if students have no learning obstacle, so that the learning process can be carried out smoothly. If a concept is fully mastered, there will be no learning obstacle. This study aims to determine the learning obstacle that occur in the material of the greatest common factor and one way to overcome these learning obstacles is to make a didactic design. The approach used in this research is qualitative method (Didactical Design Research). Data collection techniques were carried out by giving respondent ability tests (TKR), interviews, and documentation for class VII students of a SMPN in Bengkulu City. From this study, it was found that ontogeny learning barriers, namely students experiencing obstacles regarding the prerequisite material of FPB, namely division and epistemological barriers, namely the definition of factors, common factors, and the greatest common factor.
如果学生没有学习障碍,学习才能达到最佳状态,学习过程才能顺利进行。如果完全掌握了一个概念,就不会有学习障碍。本研究旨在确定材料中出现的学习障碍的最大共同因素,克服这些学习障碍的一种方法是进行教学设计。本研究使用的方法是定性方法(教学设计研究)。数据收集技术是通过对Bengkulu市一所SMPN的七年级学生进行应答者能力测试(TKR)、访谈和记录来进行的。本研究发现,个体学习障碍,即学生在FPB的前提材料上遇到障碍,即划分障碍和认识论障碍,即因素、共同因素和最大共同因素的定义障碍。

One of the learning models that can be applied in the 2013 curriculum is the inquiry learning model. By using the inquiry learning model which can build student activity in participating in mathematics learning, it is very necessary in inquiry learning so that mathematics can become a fun lesson. The same thing is also based on observations at the Mawaridussalam Islamic boarding school Batang Kuis showing that educators have carried out for one semester using the Inquiry Based Learning model. However, students experience difficulties in learning Mathematics. This is caused by differences in student learning outcomes with students' understanding abilities. The method used in this research is qualitative method. In this study, the subjects were all VII-C class students at the Mawaridussalam Islamic Boarding School for the 2022/2023 academic year with a total of 25 students. This research uses a descriptive method by describing students' difficulties in learning mathematics using the Inquiry Based Learning model in class VII-C of the Mawaridussalam Islamic Boarding School in the 2022/2023 academic year. The results of the study indicate that there are several difficulties faced by students in learning mathematics in using the inquiry learning model at the Mawaridussalam Islamic boarding school, namely: (1) technical difficulties, including the learning process which is carried out in a long way (2) students' adaptation difficulties, including feeling bored, embarrassed to ask friends, and difficult to understand learning (3) difficulties in the condition of the teacher, including the lack of preparation in lesson planning.
探究性学习模式是2013年课程中可以应用的学习模式之一。运用研究性学习模式,建立学生参与数学学习的主动性,使数学成为一门有趣的课程是十分必要的。同样的事情也基于对Mawaridussalam伊斯兰寄宿学校Batang Kuis的观察,表明教育工作者已经使用了一个学期的基于探究的学习模式。然而,学生在学习数学方面遇到困难。这是由于不同的学生的学习结果与学生的理解能力。本研究采用的方法是定性方法。在本研究中,研究对象为Mawaridussalam伊斯兰寄宿学校2022/2023学年的七年级至三年级学生,共25名学生。本研究在Mawaridussalam伊斯兰寄宿学校(Mawaridussalam Islamic Boarding School) 2022/2023学年,采用基于探究的学习模式,采用描述性方法描述学生在学习数学方面的困难。研究结果表明,Mawaridussalam伊斯兰寄宿学校学生在使用研究性学习模式学习数学时面临几个困难,即:(1)技术上的困难,包括学习过程中要走很长的路;(2)学生适应上的困难,包括感到厌烦、不好意思问朋友、难以理解学习;(3)教师条件上的困难,包括教案准备不足。

The purpose of this research is to describe the analysis of knowledge to be taught on limit of function. This research is part of the didactic transposition research on the concept of limit of function which consists of four stages. Qualitative research with descriptive method is used in this study. The target is a differential calculus course taught in the first semester at a university in Aceh. Data collection techniques consist of documentation studies and unstructured interviews. Analysis of calculus text book documents, especially on limit functions, was carried out using a praxeology approach. The results of the analysis show that the description of the differential calculus course contains material on the real number system, functions and graphs, limits of functions, continuity of functions, derivatives of functions, and applications of derivatives. This is different from the presentation of material in RPS which is compiled by a team of lecturers supporting differential calculus courses. For presentation of material in calculus textbooks, the concept of the limit of a function begins with an intuitive or informal introduction to the concept. Several cases are given to deepen the concept of limits through graphs, analytics, and numbers.

Problem-solving is one of the mathematical skills needed by students and plays an important role in helping them achieve conceptual understanding in learning mathematics. On the other hand, self-efficacy is also important because it relates to a person's belief in his ability to complete a task or achieve a goal. Based on this, this study aims to examine the relationship between self-efficacy and problem-solving abilities. To achieve the research objectives, the quantitative correlational method was used in this study. Data collection used a survey method to obtain data self-efficacy and students' mathematical problem-solving abilities. Data analysis was performed using inferential statistical analysis to prove the research hypothesis. Hypothesis testing includes analysis of correlation, regression, and coefficients of determination. Based on the results of the study, it can be concluded that there is a moderately positive relationship between self-efficacy and problem-solving abilities. where self-efficacy contributes to problem-solving abilities by 27.8%.
解题能力是学生所需要的数学技能之一,在数学学习中对概念理解起着重要作用。另一方面,自我效能感也很重要,因为它与一个人对自己完成任务或实现目标的能力的信念有关。基于此,本研究旨在探讨自我效能感与问题解决能力之间的关系。为了达到研究目的,本研究采用了定量相关法。数据收集采用问卷调查法,获取自我效能感和学生数学解题能力的数据。数据分析采用推理统计分析来证明研究假设。假设检验包括相关性分析、回归分析和决定系数分析。根据研究结果,可以得出自我效能感与解决问题能力之间存在适度正相关的结论。其中,自我效能感对解决问题能力的贡献为27.8%。

Ways of thinking siswa dalam menyelesaikan masalah pola bilangan non rutin: Suatu penelitian fenomenologi hermeneutik 思考学生解决非常规数字模式问题的方法:解释学表现学研究

This study was conducted with the aim of investigating and exploring students' ways of thinking (WoT) in solving non-routine number pattern problems. This study used a qualitative method with a hermeneutic phenomenological approach with grade 8 students at a junior high school in Banda Aceh. To achieve the research objectives, data collection was carried out using a written test instrument with a number pattern on a 4-digit palindrome, structured documentation, and clinical interviews. The results of the study show that students' WoT in solving non-routine number pattern problems is that there are four approaches used in solving non-routine problems, namely: first, determining the special case; second, determining the pattern; third, using a mathematical model; and fourth, using a similar problem. The subject of critical reflection uses the three WoTs above except for using similar problems. The subject of explicit reflection uses the three approaches above except for using a mathematical model. While Subjects who cannot solve the problem only use the strategy of identifying special cases. Another finding is that the subject of critical reflection tends to use different strategies from those given by the teacher, is unique, and gives reasons for algebraic forms. In contrast, explicit reflection subjects tend to be less flexible in using strategies and tend to use inductive or arithmetic reasons. To support students in their ability to pattern and think algebraically, teachers must accustom students to solving non-routine mathematical problems in various contexts of learning by using number patterns.
本研究旨在调查和探讨学生在解决非常规数字模式问题时的思维方式。本研究以班达亚齐一所初中八年级学生为研究对象,采用解释学现象学方法进行定性研究。为了实现研究目标,数据收集采用4位回文数字模式的书面测试工具、结构化文档和临床访谈进行。研究结果表明,学生在解决非常规数字模式问题时的WoT表现为解决非常规问题时采用了四种方法,即:一是确定特殊情况;二是确定格局;第三,运用数学模型;第四,用一个类似的问题。批判性反思的主题除了使用类似的问题外,还使用了上述三个wot。外显反射的主题除了使用数学模型外,使用上述三种方法。而无法解决问题的被试只使用识别特殊情况的策略。另一个发现是,批判性反思的主题倾向于使用不同于老师给出的策略,是独特的,并给出了代数形式的原因。相比之下,外显反思被试在使用策略时往往不那么灵活,倾向于使用归纳或算术推理。为了支持学生的模式和代数思维能力,教师必须让学生习惯于在各种学习环境中使用数字模式来解决非常规的数学问题。

This study described students' learning obstacles in understanding fraction concepts at elementary schools during online learning. The subject was 38 person of fifth-grade students of elementary schools in Bandung and Pekanbaru, Indonesia. In this study, data was collecting through tests, interviews, and curriculum documents. The data was analyzed by reducing, presenting, and making conclusions. The results show that students faced three learning obstacles: ontogenic, epistemological, and didactical. The ontogenic obstacle is caused by students' inability to understand that the fraction parts must be the same. The epistemological obstacle is an obstacle caused by the inability of students to understand the equivalence of fractions. The didactical obstacle is caused by the teaching material presented had not introduced the concept of fractions comprehensively, so the students cannot interpret fractions ultimately.
本研究描述了小学学生在网络学习中对分数概念的理解障碍。研究对象是印度尼西亚万隆和北干巴鲁小学五年级38名学生。在本研究中,通过测试、访谈和课程文件收集数据。分析数据的方法是简化、呈现和得出结论。结果表明,学生面临三个学习障碍:本体障碍、认识论障碍和教学障碍。本体障碍是由学生无法理解分数部分必须相同造成的。认识论障碍是由于学生不能理解分数的等价性而造成的障碍。教学障碍是由于教材没有全面介绍分数的概念,导致学生最终无法理解分数。

The didactical obstacle is caused by the teaching material presented had not introduced the concept of fractions comprehensively, so the students cannot interpret fractions ultimately.","PeriodicalId":348494,"journal":{"name":"Journal of Didactic Mathematics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132978848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to analyze the effect of creative thinking skills and problem-solving abilities in terms of auditory, visual and kinesthetic student learning styles. This research was conducted with a quantitative approach using a comparative descriptive method. Research data obtained by using descriptive and inferential data analysis. The research population was class XI students of SMK Negeri 1 Kisaran with a total of 340 students. The sampling technique used purposive sampling with a sample of 78 students. The instrument used a student learning style questionnaire with 39 questions, 5 questions about the ability to think creatively mathematically, and 5 questions about problem solving ability. The data analysis technique used in this study used multivariate analysis with the MANOVA test. The results of data analysis show that there is a significant influence of learning styles on creative thinking skills and problem-solving abilities of 57.1%. This means that students' learning styles, namely visual, auditory and kinesthetic learning styles significantly affect students' creative thinking abilities and students' problem-solving abilities.
