An Analysis Of Students’ Mathematical Reasoning Ability On Abstract Algebra Course

Mathematics involve the materials that can develop thinking skills, especially reasoning ability. As mentioned by [1] mathematics has axiomatic deductive characteristics that require the reasoning and thinking ability in order to comprehend it. Furthermore, [2] states that there are some different characteristics of mathematics learning for secondary and high education levels. In college, especially mathematics education study program, the materials focus on its fundamental aspects and in details. Meanwhile, mathematics for the secondary schools is on the implementation of theories or mathematical laws that taught in college level. It requires the students to have a high concentration level during the mathematics learning process. The development of mathematics is inseparable from reasoning and proofing. As stated [3], [4], [5], [6] that between mathematics and reasoning cannot be separated one another because understanding mathematics requires reasoning which can be trained through mathematical material. It indicates that mathematical reasoning is very crucial during mathematics learning. In line with this, [7], [8], [9] explain that reasoning is one of the crucial competencies in mathematics as a supporting feature in mathematics learning. [1] adds that reasoning plays a role in solving mathematical problems and the implications of reasoning are usually found in real life. Moreover, [10] points out that reasoning and proofing are the most basic aspects of mathematics learning. One of the courses taught in mathematics education study programs is abstract algebra that aims at developing students' proofing ability. Traditionally, these courses have covered the theoretical aspects of groups, rings, and fields. [11] mentions that one of the major problems

Analysis of Mathematical Reasoning Ability (MRA) with the Discovery Learning Model in Gender issues

Analysis of Mathematical Reasoning Ability (MRA) with the Discovery Learning Model in Gender issues

Abstract. This study examines students' mathematical reasoning based on Discovery learning models in terms of gender. This research was conducted at the SMPN 3 Kendari with quasi-experimental methods involving two classes with different treatments. The simple random technique is used to determine the class of research. Class VII. 6 (experimental class) consisted of 15 women and 11 men, while class VII.9 (control class) consisted of 15 men and 7 women. The instrument used was a student's mathematical reasoning ability test consisting of four items in the form of essays tested. Data processing using 2-way ANOVA with further tests using Scheffe. The conclusion obtained is that students are given a learning discovery model, the reasoning ability of male students excels in the ability to give mathematical problems verbally and in writing provided in the form of logical diagrams that contain existing data, perform mathematical manipulation related to the problem, and ensure validity as an argument, whereas women excel in the ability to draw conclusions based on relationships between mathematical concepts. The discovery learning model can increase students' mathematical penalties and overcome gender discussions.

Improving Students' Mathematical Reasoning Ability Through Problem Posing Approaches at SMPN 19 Banda Aceh

Improving Students' Mathematical Reasoning Ability Through Problem Posing Approaches at SMPN 19 Banda Aceh

With regard to mathematical reasoning abilities, the teacher has a very important role in developing mathematical reasoning abilities in students both with the learning method used, and the type of evaluation used. Improving students' mathematical reasoning skills also needs to be supported by the right learning approach so that learning objectives can be achieved. One important aspect of planning rests on the teacher's ability to anticipate needs and materials or models that can help students to achieve expected learning goals[4]. In this case, Teachers must have a method in learning as a strategy that can facilitate students to master the knowledge provided [5]. One of the predictable and possible learning approaches to improve students' mathematical reasoning abilities is learning through problem posing approach.

The Profile Of Elementary School Students’ Ability 
In Mathematical Reasoning

The Profile Of Elementary School Students’ Ability In Mathematical Reasoning

mathematics items reached 40% of the allocated time and high- complexity mathematics items reached only 3% of the allocated time.Unfortunately, TIMSS’ mathematics items consist of mathematical problems ranging from moderate to high complexity. In summary, the time allocated for mathematics learning in Indonesian schools is still mostly spent to solve mathematical problems which can be categorized as relatively easy. The low achievement of Indonesian junior high school and Madrasah Tsanawiyah students in mathematical reasoning may be caused by an internal factor, which is the previous competency of mathematical reasoning when they were in elementary schools.According to the findings of a research conducted by Watts, et al. (2016: 8 & 11), there are indications that mathematical skills demonstrated by children from the preschool stage to the first year at elementary schoolscan predict their mathematics achievement in a positive and significant wayuntil they reach the age of fifteen or enter senior high schools.This statement highlights the likelihood that the mathematical knowledge and skills showed by students in elementary schools will be reflected in the development of their abilitieswhen they later enter junior high schools, senior high schools and the next higher levels.Therefore, it can be said thatthe mathematical abilitiesof students at the junior high school level are directly affected by their prior mathematical abilitiesat the elementary school level. TIMSS assessed students’ mathematical abilities through two dimensions, namely content domain and cognitive domain. The content domain was in line with the material in the content standard, for first-grade junior high school includes number, algebra,

Mathematical Reasoning of Treatment Principle Based on “Yin Yang Wu Xing” Theory in  Traditional Chinese Medicine

Mathematical Reasoning of Treatment Principle Based on “Yin Yang Wu Xing” Theory in Traditional Chinese Medicine

Zhang’s theory, multilateral matrix theory [1] and multilateral system theory [13,14,19], have given a new and strong mathematical reasoning method from macro (Global) analysis to micro (Local) analysis. He and his colleagues have made some mathematical models and methods of reasoning [2-17], which make the mathemat- ical reasoning of TCM possible [13] based on “Yin Yang Wu Xing” Theory [18]. This paper will use steady multi- lateral systems to demonstrate the treatment principle of TCM: “Real disease is to rush down his son but virtual disease is to fill his mother” and “Strong inhibition of the same time, support the weak”.

Developing a Validated Test to Measure Students’ Progression in Mathematical Reasoning in Primary School

Developing a Validated Test to Measure Students’ Progression in Mathematical Reasoning in Primary School

Brousseau and Gibel (2005) defined mathematical reasoning as a relationship between two elements: a condition or observed facts and a consequence. Duval (2007) described mathematical reasoning as ‘a logical linking of propositions’ (p. 140) that may change the epistemic value of a claim. G. J. Stylianides (2008) viewed mathematical reasoning as containing a broader concept; besides providing arguments (non-proof and proofs), it also encompasses investigating patterns and making conjectures. In Shaughnessy, Barrett, Billstein, Kranendonk, and Peck (2004), the National Council of Teachers of Mathematics (NCTM) described reasoning in mathematics as a cycle of exploration, conjecture, and justification. This is in line with G. J. Stylianides (2008), who focused on mathematical reasoning as a process of making inquiries to formulate a generalisation or conjecture and determine its truth value by developing arguments, where argument is understood to mean a connected sequence of assertions. In a Danish context, the definition of reasoning competence in the primary school mathematics curriculum is often based on the competence report (Niss & Jensen, 2002), which, among other factors, is very specific about students being able to distinguish proof from other kinds of argumentation and makes a clear distinction between ‘carrying out’ argumentations and ‘following’ the argumentations developed by others (e.g., other students or textbooks). In the present paper, the definition of reasoning that will be tested in the developed testis a composite of definitions from the NCTM, the competence report (Niss & Jensen, 2002), and G. J. Stylianides (2008). This will be described in more detail in the Methods section.

Mathematical reasoning

Exploratory analyses of the different components of the overall Progress Test in Maths score suggest the programme may have had a positive impact on some aspects of mathematical skills. The results are indicative of a positive effect on the mathematical reasoning subscore. Given the findings of the process evaluation regarding teachers’ views that the programme was less suitable for the highest and lowest ability learners, we also conducted exploratory analyses to investigate whether there were differential impacts by prior attainment. This suggested no significant variation in the impact of the programme by prior attainment, although the estimate for pupils in the low prior attainment group is statistically significant at conventional levels. It is perhaps also worth noting that we also found some indication that pupils of lower prior attainment were more likely to drop out from the analysis sample and thus we should be cautious in drawing definitive conclusions about impacts for this group. Furthermore, given the negative skew apparent in the distribution of the raw scores, it may be the case that the assessment was more sensitive to differences in performance at the lower end of the distribution.

The Structure Of Mathematical Reasoning In Mathematical Problems

The Structure Of Mathematical Reasoning In Mathematical Problems

Students often make mistakes when solving math problems is wrong mathematical concepts, math procedures mistakes, errors in constructing concepts, etc. This results in an improper math problem solving when working on the problem. Student misconduct when solving the math problem needs to get the attention of all circles. These mistakes have an impact on the understanding of students on the next mathematical concept. Brodie (2010) in the results of his research explained that students' errors in building mathematical reasoning include: basic error, appropriate error, missing information, partial insight. Gal & Linchevski (2010) found that student difficulties in geometric representation included: (1) perceptual organization: Gestalt principles, (2) recognition: bottom-up and top-down processing; and (3) representation of perception-based knowledge: verbal vs. pictorial representation, mental images and hierarchical structure of images. Bingobali, dkk (2010) explores the causes of student math difficulties based on lecturers' views, which include: Epistemological causes, Psychological causes, Pedagogical cause. It was further discovered that students had difficulty in understanding concepts, abstracting concepts, and relating mathematics to everyday life. Therefore reasoning has a very important role in overcoming student difficulties. This study examines more in depth the mistakes made by mathematics students when solving mathematical problems by looking at the mathematical reasoning structure of students in solving mathematical problems. The study was conducted to see in more detail the types of student errors, especially from the aspects of thinking when constructing mathematical concepts. By knowing the types of errors made with the structure of reasoning, latter can be designed a learning through scaffolding or remedial scheme that will be used to restructure students' thinking.

Mathematics Learning Device Development Based On Constructivism Approach To Improve Mathematical Reasoning Skill Of Class X Students In Vocational High School (SMK)

Mathematics Learning Device Development Based On Constructivism Approach To Improve Mathematical Reasoning Skill Of Class X Students In Vocational High School (SMK)

Table 1 shows that students’ completeness criteria is still low in which there is no class that is able to reach more than 50% of minimum completeness criteria. Based on the problem as mentioned above, it is of vital importance to improve mathematics learning in order to achieve learning purpose. Mathematics learning achievement can not be separated from learning equipment employed. The learning devices being used are Students Work Sheet (LKPD) and Lesson Plan (RPP). LKPD is one of the device to help as to facilitate teaching and learning activity in order to create an effective interaction between students and teacher to improve learning activity and learning result. Widjajanti (2008:1) stated that LKPD is one of the learning resources that can be developed by teacher as a facilitator in learning activity. The designed and developed LKPD is in line with situation and condition of learning activity that will be encountered. The benefit of using LKPD is to ease teacher in conducting learning. The benefit of LKPD for the students are to help them to be independent learner and are able to comprehend and to perform a written test. By using LKPD, teacher can direct students’ activities. These activities may help students build their knowledge as well as their mathematics ability. LKPD also help teacher in conducting learning as for students it will help to them to learn independently and to learn to comprehend a task in a written form. LKPD is used by the students as a work sheet, hence they have an adequate learning resources to be learned anywhere. The development of LKPD is supported by Lesson Plan (RPP). RPP facilitates teacher to conduct learning process in order to achieve the learning purpose. The interview result with teacher of National Vocational High School (SMK N) Kayutanam which was conducted during preliminary research on August 29 th to September 29 th, 2018 indicates that the implemented lesson plan is in line with curriculum 2013. However, the main activity in the lesson plan has yet facilitate students in constructing their own knowledge. Therefore it is important to develop lesson plan to facilitate it. Hence, it is necessary to develop learning device based on constructivism approach to encourage the students to build their own knowledge in order to improve their mathematical reasoning skill. The research about learning device based constructivism approach has been conducted by many national

From research to practice: the case of mathematical reasoning

From research to practice: the case of mathematical reasoning

Valid Assessment Forms. Well over 88 tasks were developed, trialled and validated to create the learning progressions. Tasks generally comprised more than one item and scoring rubrics for each item were provided to reflect the definition of mathematical reasoning used in the project. The tasks generally enabled all students to make a start and provided opportunities to display their reasoning. For example, the Hot Air Balloon task requires students to (i) construct a graph from a table of values (time vs height), (ii) determine how long the balloon stayed at or above 250 metres, and (iii) identify when the balloon was at 400 metres and explain their reasoning. The tasks with their component items were presented as Forms with 5 to 7 tasks per form. Mixed Forms (tasks from two areas) and Standard Forms (tasks from one area only) were trialled to explore reasoning both within and across strands. Feedback from project schools suggested that they would be more interested in standard forms. As a result, four Standard Forms for each strand have been developed together with the associated scoring rubrics. Maximum score totals are different for each Form to prevent the inappropriate use of raw scores. This necessitated the provision of a Raw Score Translator for each Form that can be used to locate students on the respective learning progression for mathematical reasoning. The Forms can be used as pre-tests to determine where students are in their learning with respect to the relevant learning progression and the information derived from this can be used to inform planning and teaching. A parallel Form can then be used as a post-test to determine if there has been a qualitative shift in student behaviour and to provide feedback on the effectiveness of what was planned and taught.

Linking Teacher Learner Discourse With Mathematical Reasoning of Students With Learning Disabilities: An Exploratory Study

Linking Teacher Learner Discourse With Mathematical Reasoning of Students With Learning Disabilities: An Exploratory Study

Overall, the three students in this study present impor- tant cases. Their pre-intervention performance showed no multiplicative reasoning to solve multiplicative problems correctly. Their improved performance on the posttest sug- gests that they could learn if taught in ways that tilt the cognitive work to the students while adapting to their avail- able and evolving reasoning. Specifically, this student- adaptive instruction might have enabled Tiffany’s advance to a level of conceptualization supportive of successful solutions to mostly multiplication problems. It enabled Kathy’s advance to a higher-level conceptualization sup- portive of correctly solving multiplication and some divi- sion problems. Furthermore, it enabled Sally’s advance to a level of conceptualization supportive of correctly solving all problems. To this end, as the comparison problem types were not directly taught during the intervention, only one student (Sally) demonstrated successful transfer of multipli- cative reasoning gained from the intervention to solving a range of multiplicative word problems. As supported by existing literature (Wagner, 2006; Xin & Zhang, 2009), it seems that systematic programming for transfer is neces- sary for students with LD.

Mathematical Reasoning and the Inductive Process: An Examination of The Law of Quadratic Reciprocity

Mathematical Reasoning and the Inductive Process: An Examination of The Law of Quadratic Reciprocity

Indeed, in his second proof Gauss used the genus theory of quadratic binary forms, which consisted of establishing a bound on the number of existing genera of the quadratic forms of a given determinant and subsequently investigating the only two cases for the primes p and q. The resulting proof is far shorter than his first proof. We will not look at his second proof here, but the original proof can be found in Disquisitiones Arithmeticae, and another version of it can be seen in The Quadratic Reciprocity Law: A Collection of Classical Proofs. Instead we will investigate Gauss’s fourth proof, which made use of quadratic Gauss sums and eventually helped advance the field of algebraic number theory. The first step of our journey showed us how observation and induction helped establish one of the fundamental theorems of number theory. Next, we will look at how further attempts to refine and strengthen this theorem resulted in the discovery of new territories and gave rise to new features of the mathematical landscape.

STUDENTS LOGICAL REASONING AND MATHEMATICAL PROVING OF IMPLICATIONS. KoSze Lee A DISSERTATION

In sum, the purpose of this study is thus important in a few ways. First, with the research advancements made in the area of mathematical reasoning and proving, aspects of students’ performance in proof and proving are no longer limited to proof productions as studied in the past (Alcock & Weber, 2005; Antonini & Mariotti, 2008; Deer, 1969; Epp, 2003; Mueller, 1975; Selden & Selden, 2003). While logic training has been increasingly advocated as central to these additional aspects (Epp, 2003; Selden & Selden, 2003), an empirical inquiry of the role of logic training is in need. Without a clear understanding of the extent of logic training with regards to these additional aspects, the instructional theory and goals of developing students’ logical reasoning and mathematical proving in classrooms remained as individual teachers’ pedagogical beliefs. Second, the role of counterexamples had only gained emerging research attention for the purpose of mathematics learning and still at the stage of theory-building via case study methods (A. Stylianides & Stylianides, 2009b; Zazkis & Chernoff, 2008). This study clarified further the role of counterexamples in developing students’ mathematical reasoning and proving in

Is Practical Reasoning Presumptive?

not about a proposition or assertion. Yet Walton too, while alert to this difference, has often tended to blur it even while stating it. Commenting on a distinction between practical and “theoretical or discursive” reasoning, he states: “In the action type of critical discussion, the proposition is a practical ought-proposition that contains an imperative” (1996a, 177). This phrase is puzzling. Evidently, Walton senses that the issue in practical reasoning is not merely an “ought-proposition,” and so he adds that it “contains an imperative”—thereby inventing a new hybrid. But is a proposition that “contains” an imperative still a proposition? Is an imperative not a wholly different kind of speech act? Apparently Walton, at this stage, cannot abandon the ingrained idea that reasoning, and hence also practical reasoning, is about propositions. But that for which we argue in practical reasoning is not a proposition about what we “ought” to do, nor about what is “prudent,” although both these considerations (which are far from identical) may enter into the reasoning as premisses. The issue in practical reasoning is a proposal about what to do (a point I have contended, and whose implications I have tried to explore, in Kock 2003a, 2003b).
