Bumble Boosters: Students Doing Real Science

Bumble Boosters was a lottery grant funded cooperative project between the University of Nebraska – Lincoln Department of Entomology, the Lincoln Public Schools Science Focus Program, and the Lincoln Folsom Children's Zoo. The primary education goal of the project was to create a community of learners to conduct authentic research on bumble bees in Nebraska. Participants were actively engaged in collecting bumble bees and placing nesting domiciles. Internet technology was employed to facilitate networking between project participants. Systematic evaluation was conducted during and after the project.

Connecting Teacher Beliefs to the Use of Children’s Literature in the Teaching of Mathematics

This article presents examples that illustrate how teachers use childrens literature in the teaching of mathematics. The examples are related to four curriculum ideologies that have influenced mathematics education in the USA for the last 75 years. It discusses why it is relevant to help teachers understand the ideological positions that influence their use of childrens literature during mathematics instruction, summarizes the four ideological positions, and presents results of a study of how teachers ideological positions relate to their use of childrens literature in the teaching of mathematics. The study examines two research questionsCan an instructional tool be developed that will highlight for teachers the different ways in which they and others use childrens literature to teach mathematics? and Can that instructional tool stimulate teacher discussion and reflection about their own beliefs and the ideological nature of the instructional environment in which they learned (as students) and teach (as teachers)? Study results indicate that both questions can be answered in the affirmative.     

建立数学模型解决实际问题例举

用数学解决实际问题除了要有扎实的基础知识外,最关键的就是要将实际问题抽象成数学模型,这不仅为解决实际问题提供了一种模式,而且还能提高学生综合运用知识等方面的能力.     

Initiating Change in Prospective Elementary School Teachers' Orientations to Mathematics Teaching by Building on Beliefs

Many mathematics educators have found thatprospective elementary school teachers' beliefsinterfere with their learning of mathematics.Often teacher educators consider these beliefsto be wrong or naïve and seek to challengethem so prospective teachers will reject themfor more generative beliefs. Because of theresilience of prospective teachers' beliefs inresponse to these challenges, teacher educatorscould consider alternative ways of thinkingabout and addressing beliefs, particularly thepotential of building on rather than tearingdown pre-existing beliefs. Data from anearly-field experience linked to amathematics-for-teachers course provideevidence that when prospective teachers workintimately with children, in this case tryingto teach 10-year-olds about fractions, theexperience has the intensity from which beliefscan grow. Most of the prospective teachers inthe study were surprised that mathematicsteaching was more difficult than they hadanticipated. They began to consider theimportance of providing children time to thinkwhen solving mathematical problems. The changedescribed in the study is incremental ratherthan monumental, suggesting that building uponprospective teachers' existing beliefs will bea gradual process.     

预科文科数学素质教育初探

关于数学素质教育的思想已经被广泛接受,虽然中学数学的“素质教育”改革还有很长的路要走,但大学预科学生特别是科学生却可以立即由“应试教育”向“素质教育”转移。这需要在教育思想上、在教学手段和教学内容上都有相应的变化。     

高职院校数学课程教学改革的三个要点

用数学分析问题和解决问题的方法适用于各个不同的学科和专业,数学教学在高职院校人才培养中具有基础性作用。从培养高等技术应用型人才和创造性人才的目标出发,高职院校数学课程教学改革应强调三方面:课程体系突出应用性,教学方法重在调动学生积极性,考核评价体现以人为本。     

Before,During, and After Examination: Development of Prospective Preschool Teachers’ Mathematics-Related Enjoyment and Self-Efficacy

This article examines the stability of Norwegian prospective preschool teachers’ enjoyment of mathematics and their mathematics-related self-efficacy before, during, and after a teacher-education examination. In addition, the stability of the two constructs across countries was examined through a comparison with Germany. The data revealed partial stability (technically speaking, metric invariance) of enjoyment but not of self-efficacy. Self-efficacy increased significantly before and after the examination without decreasing enjoyment, which may be a result of increased learning time. Prior mathematical knowledge predicted the level and development of enjoyment and self-efficacy in both countries. Many Norwegian students reported low mathematics-related enjoyment and self-efficacy, including negative developments. It may be important to provide positive experiences of mathematical activities during preschool teacher education.
