Representing Nature of Science in a Science Textbook: Exploring author–editor–publisher interactions

Current reforms in elementary and secondary science education call for students and teachers to develop more informed views of the nature of science (NOS)—a process in which science textbooks play a significant role. This paper reports on a case study of the development of representations of the NOS in a senior high school chemistry textbook by the book's author, editor, and publisher. The study examines the multiple discourses that arose as the developers reflected on their personal and shared understandings of NOS; squared these with mandated curricula, the educational needs of chemistry students and teachers, and the exigencies of large-scale commercial textbook publishing. As a result, the team developed and incorporated, in the textbook, representations of NOS they believed were the most pedagogically suitable. Analysis of the data in this study indicates that a number of factors significantly influenced the development of representations of NOS, including representational accuracy (the degree to which representations of NOS conformed to informed views of the NOS), representational consistency (the degree to which representations of NOS in different parts of the book conveyed the same meaning), representational appropriateness (the age-, grade-, and reading-level appropriateness of the NOS representations), representational alignment (the degree to which NOS representations aligned with mandated curriculum), representational marketability (the degree to which NOS representations would affect sales of the textbook), and ‘Workplace Resources’ factors including availability of time, relevant expertise, and opportunities for professional development.     

Strategy Precedes Operational Effectiveness: Aligning High Graduation Rankings With Competitive Graduation Grade Point Averages

Two pivotal and interconnected claims are addressed in this article. First, strategy precedes program effectiveness. Second, graduation rates and rankings are insufficient in any account of academic progress for African American students. In this article, graduation is regarded as the floor and not the ceiling, as it were. The ideal situation in the promotion of strategy is the alignment of high graduation rates or rankings with high graduation cumulative grade point averages. This strategic alignment is precisely what needs to be formulated in the first instance before making judgments about program development and/or operational effectiveness. The work of the Office of African American Affairs of the University of Virginia provides the context for observing trends in academic performance that illustrate the optimal alignment between high graduation rankings and correspondingly high grade point averages.

A history of the book trade in the south

Long known as a difficult market for books, the South has become more receptive, largely through the efforts of booksellers. This article reviews the history of some of the South's book retailers and their role in their communities. The often strained relations between booksellers and publishers are discussed, including the role of the publisher's rep. The establishment of regional booksellers associations is described. The impact of wholesalers on retail business practices is reviewed, and the current state of the book trade in the South is assessed. Philip M. Pfeffer has served since 1978 as chairman of the board and chief executive officer of Ingram Distribution Group Inc. of La Vergne, Tennessee. Ingram Distribution Group Inc. is the parent company of Ingram Book Company, the world's largest wholesaler of trade books. Mr. Pfeffer also holds the position of executive vice president and is on the board of directors of Ingram Industries Inc. of Nashville, Tennessee. He holds bachelor's and master's degrees from Southern Illinois University in Carbondale.     

Developing Curriculum Leadership in Schools: Hong Kong perspectives

This study is designed to investigate the impact of school‐based curriculum development teams on teacher development within the tradition of school‐based curriculum development in a primary school in Hong Kong. Teacher interviews were used to evaluate the extent that teacher engagement in curriculum decision‐making processes within two school‐based curriculum development teams has led to teacher professional development which were triangulated with the videotaped meetings and tryout lessons. Qualitative evidence has revealed positively that participating teachers have developed themselves professionally through the process of planning, experimenting and reflecting (PER model) upon curriculum practice and innovation under certain conditions. However, the complexity of the structures and processes that were established for involving teachers in curriculum decision‐making processes needs further empirical and theoretical work. This paper only looks at data relating to teacher development in curriculum leadership collected in the second action cycle of the project from January to June 2005.     

Peer teaching: Academic achievement of teacher-led versus student-led discussion groups

Problem-based small-group discussions are the cornerstone of health sciences education at the University of Limburg (The Netherlands). In each of three courses, fifteen discussion groups of about eight students were randomly assigned a staff-tutor (control condition) or student-tutor (experimental condition).In two of the courses no significant differences in cognitive test achievement between the two conditions were found. In one course students tutored by staff-tutors performed significantly better than students tutored by student-tutors. However, no significant differences in test performance were found between students tutored by high-achieving versus average-achieving student-tutors. These findings contradict the congruence hypothesis from information processing theory. Several other explanations are explored.     

Design of an Industrial Management course: Bringing together engineering and educational approaches

This paper describes the process of restructuring a degree course at the Technical University of Sofia in Bulgaria so as to meet the demands of the new market economy and the changing political and educational environment. Achievements included development of a new curriculum, modularization, introduction of a new teaching quality assurance system and accreditation by the Institution of Electrical Engineers. The process of change is shown to require great sensitivity to the context and deployment of influencing strategies and skills designed to establish and maintain good relationships with a fluctuating range of stakeholders. Furthermore, the paper shows that systems engineering provides a useful framework for engaging in curriculum change in dynamic environments. One gap appears to be the need to deal explicitly with underpinning educational values, although, that said, the paper gently questions whether the accepted educational approaches can be applied to other cultures and traditions.
