eric.ed.gov har udgivet: NASA CONNECT is an annual series of integrated mathematics, science, and technology instructional distance learning programs for students in grades 6-8. This program is designed for students to learn about the evolution of flight. The program has three components–television broadcast, Web activity, and lesson guide–which are designed as an integrated instructional package. Students learn how the Wright Brothers became the first human beings to successfully design, construct, and fly an airplane and which method the Wright Brothers used in designing their airplane. Students also observe NASA engineers and researchers using problem-solving skills to design wings that will change their shape during flight. By conducting hands-on and Web activities, students make connections between NASA research and the mathematics, science, and technology they learn in the classroom. The educator… Continue Reading →

eric.ed.gov har udgivet: Using a single-subject alternating treatments reversal design, the effects of three conditions, tactile stimulation, auditory stimulation, and choice of the two, were compared on the math story problem solving of elementary students with attention problems. Students attempted and solved slightly more problems and engaged in fewer off-task behaviors in the stimulation conditions than in baseline. Effects were very modest. Students chose stimulation conditions that were related to their behavior more than their accuracy. Link til kilde

eric.ed.gov har udgivet: A set of teaching and workshop materials has been developed to illustrate the different uses of mathematics in high school mathematics and science classes. It consists of this packet of workshop activities with detailed instructions on how to use them in a combined mathematics-science workshop and a related set of problems (with solutions) that focus on the mathematical topics most commonly used in science classes. The packet includes: (1) background information on the workshops; (2) description of materials provided; (3) workshop responses; (4) a description of four types of workshops; (5) directions for and strategies used in leading the different types of workshops; (6) things to look for during workshop discussions; and (7) viewgraph (overhead transparency) masters.

eric.ed.gov har udgivet: This document points out the numbers of students who have difficulty in their required college mathematics courses. The four common syndromes identified with pupils who were experiencing a lack of success in mathematics were: (1) a lack of an adequate college or high school background in mathematics; (2) the tendency to feel that because they completed homework problems they really “knew their mathematics,”; (3) the inability to apply appropriate reading-learning strategies to their mathematics studies; and (4) a feeling of hostility over mathematics classes and anxiety over tests. These students are referred to as “underdeveloped learners,” who did not know how to study and learn mathematics. Twelve learning strategies that students should learn to apply are listed and described. A remediation strategy for these pupils that combines… Continue Reading →

eric.ed.gov har udgivet: This book was developed for teachers, youth group leaders, after-school child care providers, and parents, who may not have the time or the expertise to develop strategies for preparing students to be effective problem solvers. The content is organized in a pyramid style to make it easy to locate and grasp the information provided. Information on effective strategies for teaching general real-life problem solving is provided first. Similar information specific to real-life math problem solving follows. Together these two sections lay a foundation to prepare teachers to successfully deliver the learning activities subsequently provided. The Learning Activities section is organized by strand as identified by the Ohio Mathematics Proficiency Outcomes. Each section begins with an index of the activities included in that strand. Appendices provide additional details… Continue Reading →

eric.ed.gov har udgivet: The purpose of this research was to understand fifth grade children’s cognitive behavior as they wrote, solved and then, in small groups, shared original math story problems. Research questions examined children’s: (1) beliefs about math in this problem-writing classroom, (2) math story problem-writing behavior, (3) difficulties with their self-generated problems, and (4) small-group problem solving behavior. Case studies were conducted in the context of a teaching experiment in one fifth grade classroom. Children were engaged to write, solve and then share math story problems three or four days a week during this one year study. There were three overlapping groups of participant children. Eight children were observed as they wrote and solved math story problems. Seventeen children, including the eight previously observed, were observed via audio-recordings as… Continue Reading →

eric.ed.gov har udgivet: InterMath, a five-year effort funded through the National Science Foundation, is a statewide Internet-based project with the goal of designing and implementing a series of workshops and ongoing support programs that feature contemporary applications of technology and mathematics pedagogy in the middle grades. Technology is used to deliver the curriculum through Web-based materials and to explore the mathematics using cognitive tools such as dynamic geometry software, spreadsheets, and graphing calculators. Objectives of InterMath include: strengthening the middle school teacher’s knowledge and understanding of mathematics; providing a support structure (online and in-school) to aid teachers in implementing and integrating technology tools for doing mathematics; and providing a structured in-service curriculum that follows Georgia’s Quality Core Curriculum objectives as well as reform efforts expressed in publications by the National… Continue Reading →

eric.ed.gov har udgivet: This paper reports on the processes and results of a project on the instruction and practices of mathematics problem solving and strategies. Students in the second, third, and fifth grades were targeted to increase achievement in the area of math problem solving. Problem solving achievement was measured using performance tasks, rubrics, and tests from September 2001 to January 2002. Appendices include a teacher survey, pretests and posttests, scoring rubrics, problem solving steps and strategies, and writing stems. (Contains 26 references.) (KHR) Link til kilde

eric.ed.gov har udgivet: For the past five years, Vermont has been developing an innovative statewide assessment system in which portfolios of student work in mathematics and writing are a key element. The use of mathematics portfolios, particularly in elementary school, is a novel aspect of the assessment system. This study examines the elementary school mathematics portfolio assessment and its instructional impact by exploring the conceptions of problem solving, the knowledge of problem-solving strategies, the evaluation of problem-solving tasks, and the instructional practices of 20 fourth-grade teachers. Teachers indicated that the portfolio assessment program has enhanced their understanding of mathematical problem solving and broadened their instructional practices, but that they have encountered difficulty in understanding certain components of the reform and making the relevant changes. Teachers did not share a common… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Abstract Combinations of text and different types of pictures are commonplace in biology as in science in general. The single representations (i.e., text, picture) constituting a text–picture combination may contain redundant or complementary information. The ability to identify and integrate information in different kinds of text–picture combinations is indispensable for engaging in science and is normatively expected to be acquired in school. In this experimental study, which was not preregistered in an independent institutional registry, N = 240 undergraduate students worked on 2 constructed-response biology tasks originating from authentic final exams to obtain the higher education entrance qualification. The material carried equivalent information between conditions but consisted of redundant or non-redundant text–picture combinations or only texts. Analysis of variance revealed negative… Continue Reading →
