Reconceptualising The Professional Development Of In-Service Science Teachers In Pakistan, Nelofer Halai

Book Chapters / Conference Papers

Pakistan is a society in transition in more ways than one: politically it is still trying to find its place in the democratic nations of the world; economically it is taking steps to move closer to a market-based economy; and socially it is nurturing a more liberal and just society by reining in the religious extremists. In the aftermath of 9/11 stress has been on educational reform in a number of areas including – updating curriculum, improving access to schooling and developing teacher education. Teacher as the agent of reform is slowly gaining currency in Pakistan. The Institute for Educational …

Revving It Up! Helping Students Investigate The Forces That Power A Motor, Roy D. Unruh, Larry Escalada

Iowa Science Teachers Journal

The Electric Motors learning cycle demonstrates how magnetic fields and electric currents interact to produce a force on a moving charge. In the exploratory activity students manipulate a magnetic field to produce motion in a cone and construct an electric motor by winding an armature and field coils. In the concept development activity, students construct a simple motor with a single coil and ceramic magnets. They feel the force on a current carrying coil in a magnetic field that leads to the right-hand rule. They also analyze the operation of a motor used to power a toy car. The application …

Inside Global Warming, Roxanne Greitz Miller

Education Faculty Articles and Research

Over the last 15 years, much attention has been given to global warming, and whether the increase in the Earth's temperature in recent decades threatens the survival of life on Earth. Release of the films The Day After Tomorrow (2004), where North America is rapidly plunged into a new ice age, and An Inconvenient Truth (2006), where Al Gore focuses on the future impacts of global warming, has raised much public and media attention on the subject. As such, it's important that science teachers understand the basics behind the scientific phenomenon, the controversy surrounding the topic, and how to discuss …

The Ins And Outs Of Curbside Recycling Programs, Roxanne Greitz Miller

Education Faculty Articles and Research

In recent years, numerous municipalities in the United States and abroad have implemented either mandatory or voluntary curbside recycling programs. In most of these programs, household trash is sorted into paper, metal (steel and aluminum), and plastic products prior to its collection and then transported for processing into recycled materials. While the materials are not recycled at the curbside, the term curbside recycling generally now represents both the collection and sorting phases for these household materials.

Before we get into specifics, please note that this particular article will only address the third R of solid waste management--recycling--and not reducing or …

Imsa20: Bold Ideas, Illinois Mathematics And Science Academy

IMSA History

In the mid 1980s, the state of Illinois, recognizing a sharply increased need for highly skilled leaders in mathematics, science and technology, founded the Illinois Mathematics and Science Academy®. Twenty years later, the national demand for mathematics, science and technology leaders has never been greater. The National Academies report - Rising Above the Gathering Storm and President Bush's American Competitiveness Initiative - address the growing concern that the United States is losing its competitive advantage as countries abroad invest heavily in the education and training of scientists and engineers. Both initiatives call for increased commitments in scientific research and in …

Electronic Mathematics, Aidan O'Donoghue

Theses

Recent times have seen an explosion in the use of interactive technologies in the delivery of learning content to students in all educational sectors in Ireland. This expansion has led to the creation of modem day phenomenons such as global and ‘teacherless’ classrooms.

The research study I have undertaken is to determine if students perform to the same standard when learning through an interactive educational software application as opposed to a more traditional setting of learning ’through’ a teacher in a classroom. The application being developed for this study enables students to learn the ordinary level leaving certificate mathematics course …

The instructional sequence was in its third iteration for this study. The developmental …

Challenging A Traditional Social Norm In A Second Grade Mathematics Classroom, Lisa Egendoerfer

Electronic Theses and Dissertations

In an attempt to examine classroom dialogue within a second grade classroom, I encouraged students to participate in mathematics discussions without needing to raise their hands before speaking. I challenged this traditional social norm and established sociomathematical norms as the study progressed. My study showed the effects of this change on the dialogue of students in my classroom. Focus was placed on the participation in classroom discussions when traditional social and sociomathematical norms were in place as well as when new norms were established. The study helped determine the effects of student-centered dialogue on conceptual understanding as demonstrated in the …

The Effects Of Inquiry And Single-Gender Grouping On Second Grade Girls' Attitudes And Participation In Science, Elsy Estrada

Electronic Theses and Dissertations

Disparities between males and females in attitudes toward science have been the focus of extensive investigations. Studies have found that females feel intimidated by their male peers in science and mathematics classes, making girls less likely to participate. Their confidence in these areas decreases and they become less likely to follow related career paths. Researchers and educators are at task to find methods to provide equal learning opportunities for all students. The purpose of this action research was to investigate the effects of single-gender grouping and inquiry-based teaching on girls' participation and attitude in science class. This study took place …

The Paths To Becoming A Mathematics Teacher, Kimberly Lowry

Electronic Theses and Dissertations

Increasing numbers of mathematics teachers must be recruited in coming years, because of a growing student population, teacher attrition, calls for smaller class size, and the need to replace out-of-subject teachers. Recruitment can be made more effective and efficient, if better information on career paths is provided to decision makers. This study attempts to analyze the academic decisions which lead to the outcome "becoming a mathematics teacher". Four groups were compared and contrasted: mathematics teachers, science teachers, other teachers, and non-teachers. Science teachers were removed from the "other teachers" category because of their many similarities to mathematics teachers on the …
