eric.ed.gov har udgivet: Both the concept of sustainable development and the nature of education for sustainable development (ESD) are highly contested. ESD can be construed as a part of sustainable development policy as governments attempt to bridge the “value-action gap” between what we know we should be doing (e.g. to combat climate change) and what we actually do. Alternatively sustainability can be construed as a “frame of mind”; within this paradigm ESD is seen as a way of bringing to the surface underlying values and beliefs through the exploration of contradictions and arguments. STEM (Science, Technology, Engineering and Mathematics) education is equally contested. At one end it is seen as a pre-vocational learning or even training to encourage students to pursue science and maths in particular en route to professional… Continue Reading →

eric.ed.gov har udgivet: By participating in these class activities, students will acquire mathematical skills and at the same time learn about aging. Topics related to aging are often quantitative, and therefore, subject to mathematical analysis and procedures. The activities, which contain teacher suggestions and all student handouts, deal with seven topics. In the first activity, “Graying of America,” students extract data from a graph of U.S. population growth to solve problems which illustrate changes in the age structure of society as they and their parents grow older. “Life Expectancy” is the topic of the second activity. Students use actuarial data to compute the probability of surviving a given number of years beyond a certain age. In the third activity, “Compound Interest and Population Growth,” students gain insight into population growth… Continue Reading →

eric.ed.gov har udgivet: This unit is intended to teach estimation skills in such a way as to be relevant and useful to students as they apply them in various problem-solving activities. The teaching activities feature the earth, exploration into space, and the other worlds in the solar system. The teacher’s guide contains four modules. Module I suggests the use of several multi-media experiences to set the stage for the activities that follow. Module II, “The Solar System,” incorporates teaching activities dealing with rounding numbers, estimation of sums, differences, products and quotients, graphing, and the application of these skills in problem solving. Module III, “The Space Shuttle,” addresses the use of the space shuttle and stresses the mathematical concepts of ratio and proportion. Module IV,”The Space Colony,” uses geometric concepts as… Continue Reading →

eric.ed.gov har udgivet: The research was conducted to determine the opinions of students (10-11 years) on their engagement to mathematics course. These students are 5th grade students at a secondary school in Turkey. Qualitative research method was used in the research. At the study, designed as case study, a total of seven secondary school students were participated the research. The study group was constituted with “snowball sampling” technique of purposeful sampling methods. The data was collected by a semistructured interview form. Sixteen-page interviews obtained from the interviews were transferred to the computer. Data analysis was performed in content analysis. Codes were listed as a result of analysis. Common themes were constituted from the codes. As a result of the research, three themes, (cognitive, social and emotional engagement) eleven sub-themes and… Continue Reading →

eric.ed.gov har udgivet: This general mathematics guide, for use in grades 9-12, is one of a series of guides, K-12, that were developed by teachers to help introduce environmental education into the total curriculum. Since the nature of mathematics is abstract, students do not learn mathematics from ecology, nor ecology from mathematics. But, by observation and manipulation of environmental data, the student may inductively discover a principle in mathematics which can be reached deductively. The purpose of this booklet is to make an attempt to bridge mathematics and ecology. The guide is a supplementary handbook of ecologically-oriented mathematics exercises, designed to be self-contained and complete with answers. The exercises are built around 12 major environmental concepts that form a framework for each grade or subject area, as well as for… Continue Reading →

Do recruiters reinforce this strong selection by discriminating more against girls in more scientific subjects? Using the entrance exam of a French higher education institution (the Ecole Normale Superieure) as a natural experiment, we show the opposite: discrimination goes in favor of females in more male-connoted subjects (e.g. math, philosophy) and in favor of males in more female-connoted subjects (e.g. literature, biology), inducing a rebalancing of sex ratios between students recruited for a research career in science and humanities majors. We identify discrimination by systematic differences in students’ scores between oral tests (non-blind toward gender) and anonymous written tests (blind toward gender). By making comparisons… Continue Reading →

eric.ed.gov har udgivet: Recognizing the role numbers play in people’s everyday lives is crucial to students’ math understanding now and down the road. That’s why Bob Krech, a curriculum specialist in New Jersey’s West Windsor-Plainsboro district, likes to teach a lesson he calls “Numbers All Around Us.” This lesson uses real-world examples to show that numbers help people answer many questions, including “How much?” “How fast?” and “Where do I go?” Expert teacher Bob Krech shares strategies for teaching real-world math.

eric.ed.gov har udgivet: Some successful innovations and their underlying rationales that were implemented 50, 60, and 70 years ago could be useful in solving many educational problems. Of major concern are the gap between the actual science and mathematics curricula in most schools and the demands placed on everyday living in the modern world dominated by technology and the gap between the actual science and mathematics program in most schools and the needs, interests and abilities of the particular students in those schools. Current reforms such as Project 2061, Project Synthesis, and the National Science Teachers’ Association’s project on scope, sequence, and coordination are discussed. Integrating science with other subjects, progressive education, and other historical projects are also examined. Included are examples of innovative programs found in the United States.… Continue Reading →

eric.ed.gov har udgivet: Rural schools, like others in the nation, are enjoined to use national and state standards as the basis for educational reform. Moreover, national standards for mathematics education were established early (1989) and have been disseminated widely. Nevertheless, little is known about the dynamics of standards-based reform of mathematics in rural schools. This paper reports findings from a set of four case studies of mathematics education in rural secondary schools to provide insights into the dynamics of instructional reform. Analysis of data from interviews, observations, and documents revealed two emergent themes: (1) math teachers address calls for improvement by building on traditional practices and (2) math teachers meld traditional and reform practices.
