eric.ed.gov har udgivet: Radical reform in science and mathematics education is needed to prepare citizens for challenges of the emerging knowledge-based global economy. We consider definite proposals to establish: (1) “Standards of science and math literacy” for all students. (2) “Integration of the science curriculum” with structure of matter, energy, models and modeling as unifying themes. (3) Pedagogy promoting “scientific inquiry” and argumentation. (4) Sustained “professional development” and support for teachers. (5) “Institutional support from local universities” for continuous upgrades in curriculum and teaching practices. Physics plays a central role in all these reforms. Link til kilde

eric.ed.gov har udgivet: Educators and caregivers now have the opportunity to individualize and differentiate instructions with many technological devices never before available. Assistive Technology is being introduced in the classroom at all levels as a tool for teachers to help deliver instruction to all students. Assistive Technology is widely used to ensure appropriate educational opportunities to all students, including ELL students, students at risk, and students being considered as gifted and talented. The purpose of this article is to describe various assistive technology devices as mathematics tools to help all struggling students, not just students with disabilities, overcome math difficulties.

eric.ed.gov har udgivet: The ability to integrate technology into instruction is among the characteristics of a competent mathematics teacher. Research indicates that the vast majority of teachers in Turkey believe the use of computers in education is important, but have limited knowledge and experience on how to use technology in their instruction. This paper describes the T-Math project (http://www.t-math.org), which adapted the InterMath (http://intermath.coe.uga.edu) knowledge base for mathematics teachers in the United States and developed relevant resources for professional development of Turkish mathematics teachers to guide them in constructing useful strategies for their students while developing as expert mathematics teachers. Examples of mathematical investigations adopted and developed in the T-Math project are presented as well as the anticipated challenges and subsequent strategies for integration. (Contains 7 figures.) Link til kilde

eric.ed.gov har udgivet: Improving math achievement among U.S. students remains a high priority as results from recent math assessments continue to show room for improvement. For example, 60 percent of fourth-graders scored below the proficient level on the 2015 National Assessment of Educational Progress. On the most recent Program for International Student Assessment’s math problem-solving test, U.S. 15-year-olds outperformed students in only 6 of the 34 participating countries. In an era of increasingly rigorous state standards, teachers at all grade levels face heightened expectations to deepen their students’ understanding of mathematical concepts. Teachers may thus benefit from professional development (PD) that deepens their own conceptual understanding of math. Elementary school teachers may especially benefit from content-focused PD because they are less likely to formally study math in college than secondary… Continue Reading →

eric.ed.gov har udgivet: When teachers do not know the history of science well, when they misunderstand and underestimate its educational importance, it becomes a serious obstacle for the improvement of their methodological skills. This paper has a goal to describe author’s method how to teach the history of mathematics. This method is aimed at training math teacher’s profession-oriented qualities. These qualities form a historical component of teacher’s culture of mathematics and methodology. Besides, the paper describes the techniques and results of experimental tests for the efficiency of this method. These materials can be useful for teachers who create a cultural and historical atmosphere on math lessons at school and for university teachers who use historical mathematical ideas in their work.

eric.ed.gov har udgivet: The ubiquity of the subject of percentages in our everyday life demands that math teachers and pre-service math teachers demonstrate a profound knowledge and thorough understanding of the concept of percentages. This work, which originated from one specific lesson in an 8th grade math class, studies the conceptual understanding and problem-solving strategies of 17 pre-service math teachers. We exhibit and analyze the pre-service teachers’ misconceptions and their inefficient or false problem-solving strategies. We identify two main misconceptions. The first we name “In percentage problem is 100 always the denominator?” and the second “One can handle percentage problems using the same techniques as in numerical problems” (or Over-transferring of numerical problems). We hypothesize reasons and explanations for these misconceptions. The frequent use of percentages in everyday life and… Continue Reading →

eric.ed.gov har udgivet: Using a Mixed Methods approach, this study investigated changes in levels of self-efficacy among elementary preservice teachers following a semester course on teaching elementary students’ mathematics. Participants in this study included 347 preservice elementary teachers at a mid-size regional university who had just completed an elementary mathematics methods course. The data were collected from several semester groups. The instruments used were the Mathematics Teaching Efficacy Beliefs Instrument, interview data, and observation data collected during the clinical experience. The focus of this study was to compare the changes in teacher self-efficacy following a methods course that emphasized hands-on mathematics instruction with manipulatives by means of the 5E instructional format. The results of the paired-samples t-test indicated that there was a significant difference in the preservice elementary teachers’ self-efficacy… Continue Reading →

eric.ed.gov har udgivet: Technology is an indispensable part of the educational curriculum, and large budgets have been allocated to provide technological infrastructure in secondary education institutions in Turkey. It is important that teachers have the technological pedagogical content knowledge (TPCK) to successfully integrate technology into their courses. The aim of this study is to examine the development of the TPCK of a mathematics teacher who participated in in-service training course organized for the use of Geogebra software in geometry teaching. The in-service training is designed in accordance with the Technology Integration Model stages, and Geogebra software is used taking into account the learning outcomes of 9th and 10th grade secondary school geometry. The case study method has been employed, and data was collected through interviews, observation, self-assessment forms, and field… Continue Reading →

eric.ed.gov har udgivet: Achieving high-quality preschool at scale is challenging; to do so likely entails a combination of program standards, teacher qualifications and compensation, on-site quality monitoring, and professional development (PD). This study aims to examine the impact of investments in PD within the context of an expansion of universal preschool in one of the nation’s largest school districts. We leverage the opportunity provided by a “natural experiment” to estimate PD’s effects that embeds an evidence-based math curriculum in interdisciplinary units of study with coaching support on teacher math practices. A total of 95 schools participated in this study (51 treatment and 44 comparison schools). Treatment sites implemented more teacher-led math activities for a longer period compared to control sites. The size and magnitude of the impacts of a curriculum… Continue Reading →

eric.ed.gov har udgivet: Today it is critical to excite young people about mathematics in our high-tech STEM world we live in. Math teachers today need to embolden students to be confident in their ability to solve problems, to think and use their imaginations, to understand mathematical concepts, to be creative, and to see math as a human endeavor. The author feels that as students feel less anxious about, and more confident in their abilities to do math their performance will improve. The author has provided an in-depth literature review and offers background information on using children’s literature to teach mathematics; sharing the methods and materials possible to incorporate such literature into such math instruction in a wide range of mathematics strands. The results of using such literature in the teaching… Continue Reading →
