What is reciprocal understanding in virtual interaction?

The aim of this study is to investigate what is reciprocal understanding in virtual web-based interaction and what does it consist of. The context of this study was an international web-based pre-service teacher education (N=116) course. The study is based on an idea of shared cognition and reciprocal understanding, in particular. It is assumed that reciprocity is an essential component not only of social interaction, but also of successful virtual interaction. Since many kinds of virtual interaction, such as e-learning, web-based courses, and virtual universities are rapidly getting more common in education, there is a need to analyse the issue of reciprocal understanding in web-based learning in order to develop more profound pedagogical models. The results widely show that during this particular web-based course there was reciprocal discussion between the participants. Participants had mutual negotiations and they discussed about issues from a variety of different viewpoints. Seven different ideas were found for the mechanisms of reciprocal understanding. It is concluded that this information is useful for developing a new pedagogical model for web-based learning and enhancing the quality of virtual interaction.     

Determinants of K-2 School Teachers' Orientation towards Inquiry-Based Science Activities: A Mixed Method Study

The purpose of this study was to describe attitudes of first and second grade teachers in Benin, toward school science and their instructional preferences (inquiry-based and traditional noninquiry-based instruction), and determine some factors that could explain these attitudes and preferences. Three hundred (N=300) preparatory classroom teachers (first and second grades) were randomly selected and surveyed regarding their attitudes and preferences. Data was gathered via the Revised Science Attitude Scale, the Science Teachers' Ideological Preference Scale, and open-ended questions. The results indicated that first and second grade teachers have a low regard for school science and low level of orientation toward both inquiry-based and traditional instruction. This means that these teachers rejected traditional approaches of science teaching but at the same time did not accept inquiry teaching as a legitimate alternative. Participants' low level of orientation towards inquiry-based instruction could be explained by three dimensions of attitude; handling (handling of science equipment), time (time required to prepare and teach science), and need (the basic needs students have for science). However, time and handling significantly contributed to their orientation towards traditional noninquiry-based instruction. Four categories from the open-ended responses – perceived instructional practices, student-centeredness of the curriculum, lack of materials and supplies, and training – were used to understand and further explain participants' attitudes and instructional preferences.     

Managing Institutional Research Advancement: Implications from a University Faculty Time Allocation Study

While much is known about faculty time allocation, we know very little about how traditional managerial factors influence faculty time allocation behaviors. We know even less about the possible downsides associated with relying on these traditional managerial factors. Using survey data from the National Science Foundation/Department of Energy Survey of Academic Researchers, our study predicts faculty time allocations to grant writing as a function of pressure from administrative superiors. We then examine how pressure from administrative superiors influences faculty job satisfaction and the likelihood to pursue uninteresting research grants. Our findings indicate that faculty time spent pursuing grants increases in response to pressure from administrative superiors but that this same pressure is associated also associated with increases in pursuit of uninteresting research grants as well as decreases in work satisfaction. Our study contributes to better understanding of the merits and limitations of traditional, hierarchical approaches to managing university faculty behavior.     

A scalable admission control scheme based on time label

Resource reservation protocols allow communicating hosts to reserve resources such as bandwidth to offer guaranteed service. However,current resource reservation architectures do not scale well for a large number of flows. In this paper,we present a simple reservation protocol and a scalable admission control algorithm,which can provide QoS guarantees to individual flows without per-flow management in the network core. By mapping each flow to a definite time,this scheme addresses the problems that limit the effectiveness of current endpoint admission control schemes. The overall admission control process is described. Analysis is used to explain the reasonability of our scheme and simulation validates its performance.     

A novice mathematics teacher educator–researcher’s evolution of tools designed for in-service mathematics teachers’ professional development

This study documented the process of evolution of the continuous design and revision of the tools of a novice mathematics teacher educator–researcher (MTE-R) as he planned and implemented design-based professional development workshops for in-service mathematics teachers in Taiwan. In order to effectively facilitate teachers designing and implementing their own conjecturing activities during the workshops, the MTE-R fostered their professional learning and growth through reflection upon students’ performance. From the perspective of activity theory, this study examined the evolution of the MTE-R’s mentoring activities and tools whose design gradually changed from being based on the literature content toward being learner-centered activities with teachers as learners. Such evolution not only enhanced teachers’ learning outcomes, but also facilitated the MTE-R’s own professional growth in different areas, including mathematics, mathematics learning, mathematics teaching, teacher education, and, in particular, the extrapolation of generic examples for understanding mathematical concepts.     

Mixed G<Emphasis Type="Italic">l</Emphasis><Subscript>2</Subscript>/G<Emphasis Type="Italic">H</Emphasis><Subscript>2</Subscript> multi-channel multi-objective control synthesis for discrete time systems

This paper proposes a new approach for multi-objective robust control. The approach extends the standard generalizedl ₂ (Gl ₂) and generalizedH ₂ (GH ₂) conditions to a set of new linear matrix inequality (LMI) constraints based on a new stability condition. A technique for variable parameterization is introduced to the multi-objective control problem to preserve the linearity of the synthesis variables. Consequently, the multi-channel multi-objective mixed Gl ₂/GH ₂ control problem can be solved less conservatively using computationally tractable algorithms developed in the paper.

STUDY COURSE PROVISION IN HIGHER EDUCATION: A CASE STUDY

This paper describes the origins, development and characteristics of a study course for teacher‐education and industrial‐design undergraduates. Starting from identification by a handful of staff of a range of student needs, the course developed an informal, gaming approach that encouraged pooling of and reflection on a wide range of participants' study practices. This approach was found to require, and indeed to prove inseparable from, a broader reflection on the roles and rules, processes, products and assessment of undergraduate study. Staff — staff and staff — student negotiations, stimulated by the processes of planning, delivering and reflecting upon this course, come to be seen as constituting a promising kind of staff and curriculum development.     

Dialogical self: author and narrator of career life themes

This conceptual paper introduces the Theory of Dialogical Self to the career development literature. The life themes component of the Theory of Career Construction is the focus of application for dialogical self. It is proposed that the notion of dialogical self may contribute to understanding how individuals construct the career-related life themes. Dialogical self is thus presented as a promising theoretical construct to augment the explanatory capacity of the Theory of Career Construction and the constructivist, narrative approach to career theory in general. Implications for career counselling are presented.     

A cogenerative inquiry using postcolonial theory to envisage culturally inclusive science education

This forum constitutes a cogenerative inquiry using postcolonial theory drawn from the review paper by Zembylas and Avraamidou. Three teacher educators from African, Asian and Caribbean countries reflect on problems confronting their professional practices and consider the prospects of creating culturally inclusive science education. We learn that in Mozambique, Nepal and the Caribbean scientism patrols the borders of science education serving to exclude local epistemological beliefs and discourses and negating culturally contextualized teaching and learning. Despite the diverse cultural hybridities of these countries, science education is disconnected from the daily lives of the majority of their populations, serving inequitably the academic Western-oriented aspirations of an elite group who are “living hybridity but talking scientism.” The discussants explore their autobiographies to reveal core cultural values and beliefs grounded in their non-Western traditions and worldviews but which are in conflict with the Western Modern Worldview (WMW) and thus have no legitimate role in the standard school/college science classroom. They reflect on their hybrid cultural identities and reveal the interplay of multiple selves grounded in both the WMW and non-WMWs and existing in a dialectical tension of managed contradiction in a Third Space. They argue for dialectical logic to illuminate a Third Space wherein students of science education may be empowered to challenge hegemonies of cultural reproduction and examine reflexively their own identities, coming to recognize and reconcile their core cultural beliefs with those of Western modern science, thereby dissipating otherwise strongly delineated cultural borders.
