Role of Discrepant Questioning Leading to Model Element Modification

Discrepant questioning is a teaching technique that can help students “unlearn” misconceptions and process science ideas for deep understanding. Discrepant questioning is a technique in which teachers question students in a way that requires them to examine their ideas or models, without giving information prematurely to the student or passing judgment on the student’s model. This strategy prompts students to see the contradictions in their own model. This study focused on the analysis of small group tutoring sessions on human respiration. Individual and small group construction of mental models was analyzed after instructed with a standardized teaching sequence based on model construction and criticism theory (Rea-Ramirez in Model of conceptual understanding in human respiration and strategies for instruction, Dissertation Abstracts International, 59 (10), 5196B, 1998). Analysis provided deeper understanding of the role discrepant questioning played in this construction of understanding and suggested new models of learning.     

Knowledge sharing in global virtual team collaboration: applications of CE and thinkLets

Although a global virtual team (GVT) can provide organizations with increased competitive advantages and greater flexibility due to its unique ability to transcend traditional boundaries of time, locations, and organizational constraints, knowledge sharing in globally dispersed and culturally diverse members also poses unique challenges to organizations wishing to capitalize on diverse knowledge of GVTs. This work, therefore, examines extant literature on collaboration engineering (CE) and thinkLets and further proposes that CE and thinkLets can help organizations develop predictable patterns of knowledge-sharing behaviour and a sense of structure in GVT collaboration. Implications of using CE and thinkLets for organizational practice and research are also discussed in the virtual collaboration context.     

Education level explains participation in work and education later in life

A prolonged working life is crucial for sustaining social welfare and fiscal stability for countries facing ageing populations. The group of older adults is not homogeneous; however, differences within the group may affect the propensity to continue working and to participate in continuing education. The aim of this paper is to explore how participation in work and education vary with gender, age, and education level in a sample of older adults. The study was performed in Sweden, a context characterized by high female labour-market-participation rates and a high average retirement age. The participants were 232 members of four of the major senior citizens’ organizations. We found no differences in participation in work and education based on gender. People older than 75 years were found to be as active as people 65–75 years old in education, but the older group worked less. There were positive associations between education level and participation in both work and education. Hence, this study implies that socio-economic inequalities along these dimensions are widened later in life. This highlights the importance of engaging workers with lower education levels in educational efforts throughout life. It also emphasizes the need for true lifelong learning in society.     

Exploring interconnections between local ecological knowledge,professional identity and sense of place among Swedish fishers

The ecological knowledge of those who interact with ecosystems in everyday-life is situated in social and cultural contexts, as well as accumulated, transferred and adjusted through work practices. For them, ecosystems represent not only places for living but also places for working and defining themselves. This paper explores psychological aspects linking LEK/IEK/TEK to identity and sense of place in the context of fishery practices and management in Sweden. We analyse how knowledge of local ecosystems connect to fishers’ professional identity and their attachment to place by using the Person-Process-Place framework in integration with the Structure-Dynamic-Function framework on professional fishers in Sweden. On the basis of our results we conclude on the significance of physical as well as social and cultural features of fishing places for attachment and meaning as they are important for fishers’ local and professional identities, and also for ecological knowledge generation. Furthermore, fishers’ understanding of ecosystems complexity enhances their attachment and promotes positive emotions and behaviours for proximity maintenance.     

The growing gap between colombian education policy, official claims and classroom realities: insights from mathematics teachers' conceptions of beginning algebra and its teaching purpose

Since 1994 when the General Law of Education was issued, educational authorities have been claiming that Colombia has embarked on an educational revolution [‘La revolución educativa’ (n.d.). From the Colombian Ministry of Education website: . Retrieved 23 Nov 2004] where schools have curricular autonomy, and are to improve the quality of education by attending to the needs of the communities they serve. Teachers are urged to engage in a continuous process of constructing the curriculum which is to be anchored in the fundamental aim of educating critical citizens. The findings of this study carried out with the participation of 13 mathematics teachers with a range of teaching experiences and from different schools in Bogotá, show a totally different picture. Instead, for the teaching of school algebra, teachers emphasised the purpose of training pupils in the manipulation of symbolic expressions, as the prerequisite knowledge for the next school mathematics level and ultimately for the External Examination. I offer explanations for the identified gap and argue for the crucial need to create conditions for change at the education systemic level and for the actual empowerment of teachers.

Academic entrepreneurship (re)defined: significance and implications for the scholarship of higher education

Over the past several decades higher education scholars have conducted a significant amount of research aimed at understanding the implications of enhanced interactions between the academy and the private marketplace. Accordingly, a voluminous literature that includes conceptualizations and discussions of academic entrepreneurship has emerged. This paper used content analysis to examine how researchers have conceptualized entrepreneurship in five leading higher education journals. The analysis revealed notable patterns in the application of theoretical and conceptual frameworks of entrepreneurship to higher education phenomena, as well as observable distinctions in how entrepreneurial models are applied in specific organizational, institutional, and geographical contexts. Results suggest that there is a paucity of attention paid to the conceptual and theoretical underpinnings of entrepreneurship within higher education scholarship. We introduce a framework for strengthening the application of entrepreneurial models to higher education research that is grounded in the theoretical constructs of entrepreneurship as articulated in the economic and management literatures.     

Assessing heterogeneous student bodies using a methodology that encourages the acquisition of skills valued by employers

This work compares the results of three assessment systems used in two Spanish universities (the Universidad Politécnica de Madrid and the Universidad Católica de Ávila): the traditional system based on final examinations, continuous assessment with periodic tests and a proposed system (specially designed for heterogeneous student bodies) orientated towards motivating students. This third system involved dividing the syllabus into two different parts: a common core assessed by multiple choice tests, and a specialisation assessed by a literature review, the writing of an article and an oral presentation. The latter skills are highly valued by employers. The proposed system led to a greater pass rate than that achieved by students taking similar courses assessed by the more conventional systems. In addition, the results show that involving students in the assessment process increases their participation in their studies and generates a feeling of satisfaction and justice.     

Carbohydrate intake and ketosis in self-sufficient multi-stage ultramarathon runners

ABSTRACT

Ultra-endurance athletes accumulate an energy deficit throughout their events and those competing in self-sufficient multi-stage races are particularly vulnerable due to load carriage considerations. Whilst urinary ketones have previously been noted in ultra-endurance exercise and attributed to insufficient carbohydrate (CHO) availability, not all studies have reported concomitant CHO intake. Our aim was to determine changes in blood glucose and β-hydroxybutyrate concentrations over five days (240 km) of a self-sufficient multi-stage ultramarathon in combination with quantification of energy and macronutrient intakes, estimated energy expenditure and evaluation of energy balance. Thirteen runners (8 male, 5 female, mean age 40 ± 8 years) participated in the study. Glucose and β-hydroxybutyrate were measured every day immediately post-running, and food diaries completed daily. CHO intakes of 301 ± 106 g·day^?1 (4.3 ± 1.8 g·kg^?1·day^?1) were not sufficient to avoid ketosis (5-day mean β-hydroxybutyrate: 1.1 ± 0.6 mmol.L^?1). Furthermore, ketosis was not attenuated even when CHO intake was high (9 g·kg^?1·day^?1). This suggests that competing in a state of ketosis may be inevitable during multi-stage events where load reduction is prioritised over energy provisions. Attenuating negative impacts associated with such a metabolic shift in athletes unaccustomed to CHO and energy restriction requires further exploration.
