The present study sought to investigate perceptions of stress and coping among public school principals. School principals are daily called upon to make decisions regarding a range of unscripted events. The position can be stressful, and stress is known to interfere with sound decision making. It was predicted that present samples of school…

The present article investigates the potentialities of photo-elicitation as a technique in teacher professional development. This study analyses the process of eliciting dilemmas in four primary teachers, whose solution has proved to contribute to the teachers' education. To this end, the effect of different types of external observers'…

We address the notion that different student grouping configurations in the classroom may provide different sets of opportunities for English learners (ELs) -- students whose home language is not English (the language of instruction in the U.S.) -- to both learn science and develop a second language through different forms of social interaction.…

Using multitrait, multimethod data, and confirmatory factor analysis, the current study examined the effects of arithmetic item formatting and the possibility that across formats, abilities other than arithmetic may contribute to children's answers. Measurement hypotheses were guided by several leading theories of arithmetic cognition. With a…

In this study, metacognition refers to performing visual analysis and discrimination of real life events and situations in naïve psychology, naïve physics, and naïve biology domains. It is used, along with measuring reaction time, to examine differences in the ability of four groups of students to select appropriate pictures that correspond with…

Introduction: The present paper shows the importance of a joint use of pencil and paper activities and of technology so that students may develop a complete understanding of ratio and proportion. A previous experience with strategy use when solving ratio and proportion problems provided background. Prompted by a recognition of the cognitive…

Previous studies have found that children have difficulty solving proportional reasoning problems involving discrete units until 10 to 12 years of age, but can solve parallel problems involving continuous quantities by 6 years of age. The present studies examine where children go wrong in processing proportions that involve discrete quantities. A…

This exploratory study investigated the leadership styles of selected administrators in Tennessee's public schools. Styles of leadership were viewed against a backdrop of current brain research, and the subjects' underlying patterns of cognitive processing were identified by means of a self-report measurement of brain dominance--the Herrmann Brain…

A rationale for the teaching of thinking and problem-solving skills is outlined, and the definition of and design for teaching such skills are discussed. Developing the ability of students to think has surfaced in recent years as one of the major purposes of American education. Problem solving has been described as a major type of thinking…

A cognitive/metacognitive framework is presented for analysing applications tasks and responses to these. Conditions facilitating or impeding access to such tasks at the upper secondary level were identified using qualitative data analysis techniques within this framework. Strategies employed in exploiting, or overcoming these conditions were…

This is a record of the proceedings of the 30th annual conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of the conference is "Mathematics: Essential research, essential practice." The theme draws attention to the importance of developing and maintaining links between research and practice and…

For the twenty-seventh year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the National AECT Convention in Chicago, Illinois. The Proceedings of AECT's Convention are published in two…
