Getting to Evo-Devo: Concepts and Challenges for Students Learning Evolutionary Developmental Biology

To examine how well biology majors have achieved the necessary foundation in evolution, numerous studies have examined how students learn natural selection. However, no studies to date have examined how students learn developmental aspects of evolution (evo-devo). Although evo-devo plays an increasing role in undergraduate biology curricula, we find that instruction often addresses development cursorily, with most of the treatment embedded within instruction on evolution. Based on results of surveys and interviews with students, we suggest that teaching core concepts (CCs) within a framework that integrates supporting concepts (SCs) from both evolutionary and developmental biology can improve evo-devo instruction. We articulate CCs, SCs, and foundational concepts (FCs) that provide an integrative framework to help students master evo-devo concepts and to help educators address specific conceptual difficulties their students have with evo-devo. We then identify the difficulties that undergraduates have with these concepts. Most of these difficulties are of two types: those that are ubiquitous among students in all areas of biology and those that stem from an inadequate understanding of FCs from developmental, cell, and molecular biology.     

Exploring teaching concerns and characteristics of graduate teaching assistants

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns.     

Encouraging the development of higher-level study skills using an experiential learning framework

Teachers have only recently considered how study skills support in higher education (HE) can be delivered in a way that encourages experiential learning. This paper aims to substantiate, or otherwise, the idea that a carefully developed initiative can encourage the experiential learning of study skills. In addition, it considers whether such an approach might also allow student access to some of the higher-level study skills required for successful university study. Focus group data were used to evaluate a module delivered to sports students at a post-1992 university in the UK. This data suggested that the module facilitated learning in each stage of Kolb's experiential learning cycle. Moreover, there was evidence that the module encouraged students to undertake an ‘epistemological shift’ in which they moved from seeing knowledge as a set of uncontested facts to seeing it as something that they are expected to question and contribute to themselves.     

Student and teacher co-navigation of a course: following the natural lines of academic enquiry

Using the mountaineering metaphor of ‘natural lines’ this article describes the co-navigation of an honours course by students and teachers. It suggests the benefits and possibilities of going beyond the confines of conventional teaching and learning wisdom (as canonised in the notion of constructive alignment) and offering just and joyful ways for students to explore disciplinary knowledge. We openly explore issues of power between students and teachers in the construction of so-called partnerships, recognising the inherent challenges in moving beyond the prevailing mainstream. We suggest that a natural lines approach enables students to act as genuine co-navigators and to experience disciplinary knowledge in authentic ways and provides rich opportunities for personal reflection and development.     

The Question of Competence: the origins,strengths and inadequacies of a leadership training paradigm

During the 1990s the Teacher Training Agency showed its commitment to adopting elements of a 'competence' model of educational management training in the construction of the National Standards for Headteachers (TTA 1997, 1998). These same 'standards' have come to underpin the most ambitious programme of educational management training and development ever attempted in the UK (Glatter 1997) including the National Professional Qualification for Headship (NPQH), the Headteachers' Leadership and Management Programme (HEADLAMP) and the Leadership Programme for Serving Headteachers (LPSH). This article attempts to trace the origins of competence-based approaches to management training and suggests that the model, though having much to commend it, contains within it a variety of underlying and unresolved tensions.     

Do School Segregation and School Resources Explain Region-of-Origin Differences in the Mathematics Achievement of Immigrant Students? 1

Levels and Dronkers (2006 Dronkers, J. and Wanner, R. A. 2006. Waarom verdienen immigranten minder? Effecten van immigratiebeleid en arbeidsmarktkenmerken [Why do immigrants earn less? Effects of immigration policies and labour market characteristics]. Tijdschrift voor Arbeidsvraagstukken, 22: 379–394.  [Google Scholar]) showed that educational achievement differs between immigrant students from different regions of origin (Latin America, Northern Africa, and Western Asia). This follow-up paper establishes whether these differences in educational achievement between immigrant students from different regions of origin can be explained by school segregation, whether along ethnic or socioeconomic lines. Ethnic and socioeconomic school segregation have a negative influence on the scholastic achievement of all students, although the impact of socioeconomic school segregation is greater than that of ethnic school segregation. Ethnic school segregation affects the scholastic outcomes of native and immigrant students from some regions of origin more than those of immigrant students from other regions. The analysis shows that neither ethnic, nor socioeconomic, school segregation explains the lower mathematics achievement of immigrant students from Latin America, Northern Africa, and Western Asia.     

Achieving agri-environmental policy outcomes using models of institutional change

Abstract

Institutions involved in public policy and technological innovation are concerned with processes that influence the behaviour of people. This paper reports on research in the New Zealand dairy industry that is seeking to develop improved process models for managing change in a range of policy, industry and business contexts. The Practice Interplay Model was used to evaluate mediating methods for negotiating environmental and production outcomes within the context of a farm dairy effluent management case study. Significant misalignments between research, farming, extension and policy practitioners' expectations and perceptions of factors required for effective farm dairy effluent management were found. The combination of interactive workshops linked to quantitative verification and testing and follow-up interviews enabled a depth of investigation that was rich in information yet cost-effective in terms of research resources. The process used identified opportunities to change the actions of system participants and alignment between them. It enabled strategies to be agreed that would continually improve and strengthen the process of change. Further development and application of the Practice Interplay Model to policy problems, including the ongoing development of tools and techniques used within the methodology, has the potential to break though into a new policy-development paradigm in New Zealand.     

‘I make sure I am safe and I make sure I have myself in every way possible’: African-American youth perspectives on sexuality education

High rates of pregnancy and sexually transmitted infections play a major role in the physical, mental, and emotional health of young people. Despite efforts to provide sexuality education through diverse channels, we know little about the ways in which young people perceive school- and community-based efforts to educate them about sexual health. Forty-eight African-American young people participated in six focus groups to discuss their sexuality education experiences. Three major themes emerged that highlight experiences and perspectives on optimal strategies for promoting sexual health. These themes were: (1) experiences with school-based sexuality education (SBSE), (2) seeking information outside of schools, and (3) general principles of youth-centred sexuality education. Young people in the focus groups expressed their varying satisfaction with SBSE due to the restricted content covered and lack of comfort with the instruction methods. Participants described how they reached outside of SBSE for sexuality education, turning to those in the community, including local organisations, health care providers, and peers, also expressing variability in satisfaction with these sources. Finally, participants identified three important principles for youth-centred sexuality education: trust and confidentiality, credibility, and self-determination. These findings give voice to the often-unheard perspectives of African-American young people. Based on their responses, it is possible to gain a better understanding of the optimal combination of school-, family-, peer-, and community-based efforts to support young people as they move towards adulthood.     

Research productivity in communication: An analysis, 1996‐2001

The study provides an analysis of those scholars who produced a substantial number of articles in 24 communication journals during the period, 1996‐2001. The purpose of the study was to update the information provided in previous studies. Using data similar to that previously found in the Index to Journals in Communication Studies, the authors found that during the period a number of new names has appeared. As a result, the authors develop a list of the top one percent (50) of those researchers, as well as providing data on the institutions which these scholars represent. The minimum number of articles necessary during the period to be included was nine.
