Teacher Influence in the Classroom: A Preliminary Investigation of Perceived Instructor Power,Credibility, and Student Satisfaction An earlier version of this paper was presented on a program of the Communication Education interest group at the annual convention of the Central States Communication Association,Milwaukee, WI,April 2002.

The purpose of this study was to examine the relationships between perceived teacher power, teacher credibility, and student satisfaction. Respondents were 67 undergraduate students (30 males and 37 females) enrolled in Communication classes at a southwestern university. Students’ perceptions of their teachers’ expert, referent and reward power use were found to be positively related to their perceptions of their teachers’ competence, caring, and trustworthiness. Teacher power use contributed to the prediction of a significant amount of variance in teacher credibility. Additionally, student satisfaction was positively and significantly related to both teacher referent power and expert power. Surprisingly, students’ perceptions of coercive power were not significantly and negatively related to student satisfaction. Implications, limitations and suggestions for future research are discussed.     

Interdisciplinary Majors Involving Computer Science

This article discusses the intent and nature of joint majors involving computer science and suggests broad guidelines to motivate and configure the course of study. We argue that a well‐designed joint major is greater than the sum of its parts so long as there exists a significant overlap in subject matter between disciplines which becomes the focus of study. We define the relatedness of the two disciplines involved in a joint major not along traditional lines, but in terms of a primary model for the study of computer science and the broad application of its computer science core curriculum to a variety of other disciplines. We argue that the joint major that includes computer science should entail a substantial theoretic component. This argument bars those combinations that require only programming (or information processing) skills for the joint major. Finally, we suggest, with illustrations, three concrete motivations behind the design of joint majors that include computer science as one of their components.     

Setting expectations for good education: how Dutch school inspections drive improvement

With decentralisation becoming increasingly widespread across Europe, evaluation and accountability are becoming key issues in ensuring quality provision for all (Altrichter & Maag Merki, 2010; Eurydice, 2004). In Europe, the dominant arrangement for educational accountability is school inspections. The purpose of this research is to identify and analyse the ways in which school inspections in The Netherlands impact on the work of schools. The results of 2 years of survey data of principals and teachers in primary and secondary schools show that inspection primarily drives change indirectly, through encouraging certain developmental processes, rather than through more direct and coercive methods, such as schools reacting to inspection feedback. Specifically, results indicate that school inspections which set clear expectations on what constitutes “good education” for schools and their stakeholders are strong determinants of improvement actions; principals and schools feel pressure to respond to these prompts and improve their education.     

Competing Views of Embryos for the Twenty-First Century: Textbooks and Society

It might seem that an embryo is an embryo, and that there would be a fact of the matter. That seems especially true with respect to the way embryos are presented in textbooks, including high school biology textbooks. This paper looks at three co-existing, competing, and often conflicting views of embryos. Then with a close study of twentieth century high school biology textbooks, it explores suggestions about the ways those books have influenced public impressions of embryos.     

Modelling activities integrating construction and simulation supported explanatory and evaluative reasoning

ABSTRACT

Model-based instruction offers numerous benefits to students, including increased content knowledge and critical thinking. This study explored the differences in the knowledge outcomes and reasoning processes employed by undergraduate students in an introductory biology lab as they constructed, revised, and simulated a computational model of a prokaryotic gene regulatory system. We analysed post-lesson conceptual models (n?=?335) and audio-recorded small group discussions (n?=?10) of students that either constructed and revised a computational model and then investigated a pre-constructed computational model or only investigated a pre-constructed computational model to determine the impact of constructing and revising a computational model. No significant differences were found between the mental models of students who constructed and revised a computational model and those who only simulated a pre-constructed computational model. However, this study demonstrated that constructing and revising a model before simulating it offered additional benefits to students by fostering deeper cognitive reasoning processes. Constructing and revising a model elicited more explanatory and evaluative reasoning and prompted students to discuss the underlying mechanisms of the biological system.     

Implementing the democratic principles and practices of student-centred curriculum integration in primary schools

Student-centred curriculum integration (CI) is a concept underpinned by democratic education. It places students at the centre of learning, involving them in classroom decisions and curriculum planning. Most research on this approach has been situated in the middle years, but this study focuses on primary schooling.

This project examined what happened when three teachers, located in three New Zealand schools, explored the democratic principles and practices inherent in student-centred curriculum integration. The project utilised participatory action research (PAR) methodology supported by multiple data sources. The findings indicated that this form of curriculum design provides relevant, engaging and equitable learning environments. The teachers found that by slowly increasing the level of student inclusion they gained the confidence and competence to collaboratively co-construct curriculum with students.
