On the Operationalisation of Conceptions of Learning in Higher Education and Their Association with Students’ Knowledge and Experiences of Their Learning

Conceptions of learning, as well as other associated aspects of prior knowledge, are theoretically important factors in influencing the manner in which the content and context of learning are engaged. The present study reports on: (a) the operationalisation of some of these factors aimed at isolating sources of explanatory variation that can be used for modelling purposes; and (b) a conservative exploration of the discriminatory power of, and exhibited patterns of association between, such sources of variation as have been isolated. Based on a conservative analytical approach, the results of the present study do not support a single clearly defined empirical model of conceptions of learning and associated constructs. Instead, there is consistent evidence that underlying empirical structures appear to be sensitive to the response context and other factors.     

College Students’ Relationship Between Trauma and Disordered Eating

Among college students, a correlation exists between trauma exposure and eating disorders. Although disordered eating behaviors are more prevalent than eating disorders, the relationship between different types of trauma exposure and disordered eating is unknown. The current study explored this relationship. One hundred two participants completed questionnaires on disordered eating and trauma exposure. Results showed that (a) sexual abuse was a significant predictor of concerns regarding food and weight gain (p < .05) and (b) other form of trauma (e.g., natural disaster) was a significant predictor of difficulties in individuals’ relationship with food (p < .05). Clinical implications, especially those related to trauma assessment and disordered eating behaviors, are discussed. The importance of examining the impact of nonsexual trauma is described, and the clinical utility of breaking eating pathology down into specific abnormal attitudes and behaviors is highlighted.     

Carbohydrate intake and training efficacy – a randomized cross-over study

Carbohydrate (CHO) availability during endurance exercise seems to attenuate exercise-induced perturbations of cellular homeostasis and might consequently diminish the stimulus for training adaptation. Therefore, a negative effect of CHO intake on endurance training efficacy seems plausible. This study aimed to test the influence of carbohydrate intake on the efficacy of an endurance training program on previously untrained healthy adults. A randomized cross-over trial (8-week wash-out period) was conducted in 23 men and women with two 8-week training periods (with vs. without intake of 50g glucose before each training bout). Training intervention consisted of 4x45 min running/walking sessions/week at 70% of heart rate reserve. Exhaustive, ramp-shaped exercise tests with gas exchange measurements were conducted before and after each training period. Outcome measures were maximum oxygen uptake (VO_2max) and ventilatory anaerobic threshold (VT). VO_2max and VT increased after training regardless of CHO intake (VO_2max: Non-CHO 2.6 ± 3.0 ml*min^?1*kg^?1 p = 0.004; CHO 1.4 ± 2.5 ml*min^?1*kg^?1 p = 0.049; VT: Non-CHO 4.2 ± 4.2 ml*min^?1*kg^?1 p < 0.001; CHO 3.0 ± 4.2 ml*min^?1*kg^?1 p = 0.003). The 95% confidence interval (CI) for the difference between conditions was between +0.1 and +2.1 ml*min^?1*kg^?1 for VO_2max and between ?1.2 and +3.1 for VT. It is concluded that carbohydrate intake could potentially impair the efficacy of an endurance training program.     

Knowledge sharing and team trustworthiness: it's all about social ties!

This paper empirically examines knowledge sharing within innovation teams and explores the relationship between knowledge sharing and trust. This relationship has generally been identified in the literature as an important aspect of knowledge management. However, its pertinence to knowledge transfer within and between teams is less obvious. The case study based on four information technology R&D teams in Taiwan suggests that trust between a knowledge holder and a receiver may not exist. In fact, it can be connected by a mediator, although the use of social relationship in which trust is rooted in both host and visitor's trust of the mediator. Thus, trust may be substituted by the social relationship in certain specific contexts.

How Community College Faculty Members May Improve Student Learning Productivity in Their Online Courses

Eleven experienced community college faculty members were interviewed to elicit examples of how they improved student learning productivity in their online courses. The 11 faculty members represented eight different states, nine different fields or disciplines, and all were permanent or full-time faculty members at community colleges in the southern or western states. Based on a thematic analysis of the examples given, improvement in student learning occurred by (a) emphasizing seven approaches to increase student engagement, (b) using six different structuring tactics to focus student attention on learning, (c) using assessment techniques to improve learning, and (d) pursuing a personal passion for online teaching. These findings suggest that faculty can and do find ways to use different tools in different ways to improve student learning productivity in community colleges.     

LEARNING ABOUT LEARNING: EARLY CHILDHOOD STUDENTS EXPLORE REGGIO

One of the greatest challenges we face as an early childhood professional community is providing short-term, affordable professional development that results in depth of understanding and change of practice. The University of Wyoming Early Childhood Summer Institute is a model for professional development that fosters reflection, inquiry, and change in beliefs and practice for early childhood practitioners. The 3-day Institute has an innovative structure and constructivist quality that allows for intense, authentic learning among participants. The research reported in this article supports this claim and clarifies key components of the model critical to the transfer of knowledge gained through the Institute to application in the workplace. In a 6-month follow-up study after the Institute, participants, Institute facilitators, and keynote speakers describe how the Institute has continued to influence their beliefs and practice over time.

Exploring a Plum

I had to do an observation of a child for a class that was part of the Institute, so I chose my grandson who was about 13 months at the time. I had planned on giving him some really cool blocks and things. Instead (it was right after I went to the Institute), I was sitting there eating a plum trying to figure out how to set things up and I looked up and he was watching me so intently that I decided to do my observation on that. I introduced him to his first plum and sat back and watched him explore and discover it. I watched him, I took pictures of him and put the story and pictures together. I could really see what they were talking about at the Institute … just stepping back and watching. (T. D. Participant 6).     

Introducing an observational measure of standards-based mathematics teaching practices: Evidence of validity and score reliability

The purpose of this study is to introduce a measure of standards-based mathematics teaching practices, the Mathematics Scan (M-Scan), and to examine its validity and score reliability. First, we define standards-based mathematics teaching practices based on eight dimensions that have emerged in recent conceptualizations by researchers and in the context of existing observational measures. Second, we present three sources of validity evidence: content review by experts, analysis of response processes of coders, and convergent and discriminant patterns with existing observational measures. Third, we provide evidence of inter-coder (or inter-rater) reliability through analyses of variance components and calculation of reliability coefficients, using the framework of generalizability theory. Results show the M-Scan holds promise as a useful tool in mathematics education research, measuring indicators of standards-based teaching practices unique to the subject of mathematics.     

Students reflecting on test performance and feedback: an on-line approach

Undergraduate students accessing on-line tests in Human Biology in three Western Australian universities were asked to complete an on-line post-test reflective survey about their perceptions of their test performance in light of automated feedback. The survey allowed pre-determined choices and comment text boxes relating to students’ perceptions of their performance, self-identified areas of difficulty and suggested strategies for improving test performance. One-third of students undertaking on-line tests responded to the optional survey, and 60% of respondents thought reflecting on feedback was useful. Students reflecting on formative rather than summative assessment reported a more strategic approach to testing, often using it to assess their knowledge and prepare for future assessment. Their reflections were more internally focused on motivation and preparation compared with those assessed summatively. Respondents were more likely to be female, older, more experienced learners who had scored well in the test. Younger respondents expected higher scores than they achieved and were less likely to reflect, but, when they did, were more likely to select pre-determined reasons for their performance and less likely to suggest strategies for improvement. These results support formal training and scaffolded integration of reflection into on-line assessment feedback, especially for less experienced learners.
