Pre-Service Teachers and Mathematics: The Impact of Service-Learning on Teacher Preparation

Lisa Kirtman

In spite of repeated reform efforts, there is research and data that suggest that teachers lack the needed knowledge to successfully teach elementary mathematics. Some argue that teachers lack the needed content knowledge while other argue that a lack of confidence and practice are impacting teachers' ability to successful teach mathematics. As a result of these issues, this paper looks at the impact of a service-learning experience on pre-service teachers' confidence and preparation in the area of mathematics. The service-learning experience had a number of intended and unintended outcomes. As a result of the service-learning experience, pre-service teachers noted increased understanding, innovation and confidence in the area of mathematics.

Teaching and Coherent Science:  An Investigation of Teachers' Beliefs about and Practice of Teaching Science Coherently

Francis Eberle

This article is about an investigation of six middle school science teachers' beliefs and instructional practice about the coherence of the science they teach as articulated by National Science Education Standards (NRC, 1996). Many well intentioned reform efforts focus on improving content knowledge of teachers, but many classroom teachers regularly miss opportunities to provide conceptual connections within the science ideas building the sense of coherence in science. This investigation involved a quasi experimental study to examine the efficacy of a method for collecting data about middle school science teachers' thinking about science and to determine if they teach science coherently. The teachers were surveyed, interviewed, provided concept maps about their thinking of the science they taught, and observed to investigate whether their practice reflects their beliefs. An examination of the teachers’ beliefs, stated and unstated curriculum, the connections among topics and the nature of science revealed that one, the observation tool may have merit for identifying the content and connections among science topics, and two, that teachers' stated beliefs consistent with the National Science Education Standards' vision for coherent science, did not match their demonstrated practice. The content taught could be characterized in three ways; coherent content and few connections, coherent content and connections, and not coherent content. This indicates for this group of middle school science teachers that knowing how they think about science and how those beliefs are reflected in their teaching is complex. This study can inform teacher education and professional development efforts about the need to move beyond just content enhancement to examine prior beliefs about the connections of concepts within science.

Gender Differences Regarding Mathematics Achievement:  The Case of Turkish Middle School Students

Mine Isiksal & Erdine Cakiroglu

The purpose of this study was to explore gender differences in mathematics achievement as demonstrated by performance on the mathematics subsection of a nationwide high school entrance examination in Turkey. In this study, the cities in Turkey were separated into five groups according to their level of economic development. The analysis was based on 2647 students that were randomly selected from these five different groups of cities. Although results indicated a statistically significant difference in mathematics achievement in favor of cities with the highest economic status, the effect size was quite small, which indicates the difference was not practically significant. Results also showed the effect sizes for gender differences in mathematics achievement were very small in all groups of cities. It was concluded that socio-economic development of the regions was not a critical factor for gender differences in mathematics achievement.
