Eric.ed.gov – Visual Arts and the Teaching of the Mathematical Concepts of Shape and Space in Grade R Classrooms

eric.ed.gov har udgivet: This article addresses the need for research in the areas of Grade R curriculum and pedagogy, Grade R teacher professional development, and early years mathematics teaching. More specifically, it responds to the need for teacher professional development in Grade R mathematics teaching of the geometric concepts of space and shape. The article describes a study about teachers’ understanding of how visual arts can be used as pedagogical modality. The study was prompted by the findings of a ‘Maths and Science through Arts and Culture Curriculum’ intervention undertaken with Grade R teachers enrolled for a Bachelor of Education (Foundation Phase) degree at a South African university. Post-intervention, teachers’ classroom practices did not change, and they were not using visual arts to teach mathematical concepts. The lessons learned from… Continue Reading

Eric.ed.gov – Look down from the Sky: Is It a Bird? Is It Superman? No, It’s a Plane

eric.ed.gov har udgivet: The plane problem is a real-world problem, presented without any suggestion as to how it might be solved. It arose unexpectedly as the author was messing around on the internet, not thinking about maths at all. She did not encounter the problem in a maths lesson, nor as homework in the middle of a unit on a particular topic, and so she had no clues about what method was going to be useful, or even if she would be able to solve it. All she had–initially at least–was the image of the plane and a mystery: at what altitude is it flying? There is something satisfying about seeing how mathematics can solve a mystery that may appear, at first sight, to be intractable. Students need the opportunity… Continue Reading

Eric.ed.gov – Math Academy: Can You See It in Nature? Explorations in Patterns & Functions. Book 2: Supplemental Math Materials for Grades 3-8

eric.ed.gov har udgivet: Created by teachers for teachers, the Math Academy tools and activities included in this booklet were designed to create hands-on activities and a fun learning environment for the teaching of mathematics to students. This booklet contains the “Math Academy–Can You See It in Nature? Explorations in Patterns & Functions,” which a teacher can use to enhance his/her math instruction while staying true to the academic rigor required by the state standards framework. It contains all the activities used for the patterns and functions Math Academy. This Math Academy is designed to help students understand the connection between geometric and numerical patterns (younger students) as well as between patterns and functions (older students). One may choose to implement a grade-level or school-wide Math Academy as the author originally… Continue Reading

Eric.ed.gov – (Mis)Conceptions about Geometric Shapes in Pre-Service Primary Teachers

eric.ed.gov har udgivet: During the last reform, Slovakia has reduced geometry in curriculum in primary mathematics education. Pre-school education schools devote more time to geometry in curriculum, but this is not mandatory for all the children. In the primary schools, teachers devote very little lessons time to this problem. These lessons are mainly focused on technology of drawing rather than on creating the right conceptions, which results in below the average scores on international test results in Slovak students. One possible solutions is to improve the level of geometrical knowledge of primary education teachers and pre-service primary education teachers. This paper is focused on the knowledge of plane geometric figures and their properties. We found out that pre-service teachers in primary education have many misconceptions that started when these students… Continue Reading

Eric.ed.gov – Geometry Teaching via Origami: The Views of Secondary Mathematics Teacher Trainees

eric.ed.gov har udgivet: Considering the performances of the students in the Timss and Pisa examinations, it is seen that they can not solve the problems, do not animate the objects they can not ask geometry questions in three dimensions and can not understand them. For this reason, origami lessons should be put into teacher training programs. Secondary teacher trainees were examined in this study according to their views about using origami activities in maths courses. This qualitative study was carried out with 18 secondary mathematics teacher trainees. Data were gathered by semi-structured interview and 3D tangible materials. Findings revealed that prospective teacher candidates can associate large quantities of mathematical and geometric concepts with some achievements and that they have a constructive view on origami activities. However, it was seen that… Continue Reading

Eric.ed.gov – Setting the Stage with Geometry: Lessons & Worksheets to Build Skills in Measuring Perimeter, Area, Surface Area, and Volume. Poster/Teaching Guide. Expect the Unexpected with Math[R]

eric.ed.gov har udgivet: “Setting the Stage with Geometry” is a new math program aligned with the National Council of Teachers of Mathematics (NCTM) standards that is designed to help students in grades 6-8 build and reinforce basic geometry skills for measuring 2D and 3D shapes. Developed by The Actuarial Foundation, this program seeks to provide skill-building math activities to help students become successful in the classroom and in real-world situations outside of school.

Eric.ed.gov – Can Classification Criteria Constitute a Correct Mathematical Definition? Preservice and In-Service Teachers’ Perspectives

eric.ed.gov har udgivet: The study reported here addresses pre-service and in-service teachers’ attitudes toward mathematical-geometrical definitions. The goal of the study is to investigate whether understanding the role of definitions as classification and identification criteria will guarantee that participants: (1) accept that there may be more than one equivalent definition for particular concept; and (2) accept the minimal definitions which include necessary and sufficient attributes to be legal definitions. Fifty-three math educators participated the study, including 22 preservice junior teachers, 19 pre-service senior teachers and 12 in-service senior teachers. The findings indicate that considering (an) attribute/s as sufficient in order to classify examples and non-examples of the concept did not guarantee considering this/ese attributes as concept definition. 56% of the participants did not accept equivalent definitions as legal definitions, 36%… Continue Reading

Eric.ed.gov – In-Service Zimbabwean Teachers’ Views on the Utility Value of Diagrams in the Teaching and Learning of Geometry

eric.ed.gov har udgivet: Geometry is an essential component of mathematics which promotes the development of critical thinking and problem-solving skills. Geometry shapes are an integral part of our lives. This study focused on the teachers’ practices, specifically on how teachers ought to be equipped with a good understanding of the effectiveness of the use of diagrams in geometry teaching and learning. A mixed-method approach comprising of questionnaires and interviews was used in this study. Ninety-one teachers participated in this study. The research findings were categorized using the four themes of utility, positive attitudes, negative attitudes, and teachers’ use of diagrams in geometry class. The study showed that diagrams are effective in the teaching and learning of geometry concepts. It is recommended that teachers could do well if they make use… Continue Reading

Eric.ed.gov – Visual Images Related to Angle Concept in the 5th Grade Maths Coursebooks

eric.ed.gov har udgivet: There are different perspectives in the literature on the examination of visual images used in course books. In this study, illustrations from the visuals used in geometry in the lower learning area of school mathematics were examined and summarized first by researchers and then by teachers and students. For many students, the mathematics coursebook is the first material they encounter in understanding the course content and conveying the mathematics culture. In this study, the illustrations related to the concept of Angle used in mathematics coursebook, two books published abroad, two books published in Turkey, for 5th-grade students were analyzed. The type of research is Document Analysis and the illustrations were examined in qualitative and quantitative terms. In this way, the study aimed to analyze the contribution of… Continue Reading
