Emotional arousal of beginning physics teachers during extended experimental investigations

Teachers often have difficulty implementing inquiry‐based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations (EEIs) produced emotional states that mediated their teaching practices. Against rhetoric of fear expressed by their senior colleagues, three of the four teachers were surprised by the positive outcomes from their supervision of EEIs for the first time. Two of these teachers experienced high intensity positive emotions in response to their students' success. When student actions/outcomes did not meet their teachers' expectations, frustration, anger, and disappointment were experienced by the teachers, as predicted by a sociological theory of human emotions (Turner, J. H. (2007). Human emotions: A sociological theory. London, England: Routledge). Over the course of the EEI projects, the teachers' practices changed along with their emotional states and their students' achievements. We account for similarities and differences in the teachers' emotional experiences in terms of context, prior experience, and expectations. The findings from this study provide insights into effective supervision practices that can be used to inform new and experienced teachers alike. © 2012 Wiley Periodicals, Inc.

Exploring Engineering instructors’ views about writing and online tools to support communication in Engineering

To be fully prepared for the professional workplace, Engineering students need to be able to effectively communicate. However, there has been a growing concern in the field about students’ preparedness for this aspect of their future work. It is argued that online writing tools, to engage numbers of students in the writing process, can support feedback on and development of writing in engineering on a larger scale. Through interviews and questionnaires, this study explores engineering academics’ perceptions of writing to better understand how online writing tools may be integrated into their teaching. Results suggest that writing is viewed positively in the discipline, but it is not believed to be essential to success in engineering. Online writing tools were believed to support a larger number of students, but low knowledge of the tools limited academics’ understanding of their usefulness in teaching and learning. Implications for innovation in undergraduate teaching are discussed.     

Exploring emotional climate in preservice science teacher education

Classroom emotional climates (ECs) are interrelated with students’ engagement with university courses. Despite growing interest in emotions and EC research, little is known about the ways in which social interactions and different subject matter mediate ECs in preservice science teacher education classes. In this study we investigated the EC and associated classroom interactions in a preservice science teacher education class. We were interested in the ways in which salient classroom interactions were related to the EC during lessons centered on debates about science-based issues (e.g., nuclear energy alternatives). Participants used audience response technology to indicate their perceptions of the EC. Analysis of conversation for salient video clips and analysis of non-verbal conduct (acoustic parameters, body movements, and facial expressions) supplemented EC data. One key contribution that this study makes to preservice science teacher education is to identify the micro-processes of successful and unsuccessful class interactions that were associated with positive and neutral EC. The structure of these interactions can inform the practice of other science educators who wish to produce positive ECs in their classes. The study also extends and explicates the construct of intensity of EC.     

Perception of spiritual health: A qualitative content analysis in Iranian older adults

The present study was performed with the aim to explain older people’s perceptions of spiritual health. It was conducted using the conventional content analysis method. Twelve individuals aged 60 years or older with normal cognition participated in the study using purposive sampling. Data were collected by in-depth interviews. Data analysis performed using standard method of thematic analysis.The average age of the study participants was 71.25 ± 9.48. The data analysis resulted in three main categories of spiritual insight, spiritual function, and spiritual affection. The spiritual insight included cognition of God and belief in Him, understanding of the divine religions and belief in them, self-cognition, cognition of the creation, and belief in the hereafter. This category included the two subcategories of spiritual cognition and spiritual belief. Spiritual function represented the interactions that the older people experienced in relations with God, themselves, and others. This category consisted of the subcategories of relationship with God, relationship with others, and self-cultivation. The spiritual affection included loving God and other humans and consisted of the three subcategories of spiritual affections to God, others, and oneself. This study presents in-depth data on the concept of spiritual health from older people’s viewpoints. These findings would help healthcare teams in designing appropriate interventions for older people’s health promotion. Also, by using the results of this research, health researchers design more appropriate tools for measuring spiritual health based on older people’s perception of the concept of spiritual health.     

Examining the relations of time management and procrastination within a model of self-regulated learning

The primary goal of this study was to investigate whether college students’ academic time management could be used to understand their engagement in traditional and active forms of procrastination within a model of self-regulated learning. College students (N = 446) completed a self-report survey that assessed motivational and strategic aspects of self-regulated learning, time management, and procrastination. Results of regression analyses indicated that self-efficacy and metacognitive strategies initially were significant predictors of traditional and active forms of procrastination. Incorporating time management in the analyses increased the amount of the variance explained and, even in the presence of the motivation and strategy variables, time management emerged as an important predictor of both traditional and active forms of procrastination. Findings support the conclusion that academic time management is a key aspect of self-regulated learning and, as such, it can be useful for understanding the extent to which college students procrastinate when doing their academic work.     

Temporal expert profiling: With an application to T-shaped expert finding

Cost optimization continues to be a critical concern for many human resources departments. The key is to balance between costs and business value. In particular, computer science organizations prefer to hire people who are expert in only one skill area and have a slight superficial knowledge in other areas that gives them the ability to collaborate across different aspects of project. Community Question Answering networks provide good platforms for people and organizations to share knowledge and find experts. An important issue in expert finding is that an expert has to constantly update his knowledge after being saturated in his field of expertise to still be identified as expert. A person who fails to preserve his expertise is likely to lose his expertise. This work justifies this question that does take the concept of time into account improve the quality of expertise retrieval. We propose a new method for T-shaped expert finding that is based on temporal expert profiling. The proposed method takes the temporal property of expertise into account to mine the shape of expertise for each candidate expert based on his profile. To this end, for each candidate expert, we take snapshots of his expertise trees at regular time intervals and learn the relation between temporal changes in different expertise trees and candidates’ profile. Finally, we use a filtering technique that is applied on top of the profiling method, to find shape of expertise for candidate experts. Experimental results on a large test collection show the superiority of the proposed method in terms of quality of results in comparison with state-of-the-art.     

What's in their baggage? The cultural and social capital of Australian students preparing to study abroad

Governments and educational institutions promote study abroad in the belief that it offers valuable learning experiences for all students. Yet studies suggest that equitable access to study abroad is more myth than reality. This study took a narrative approach supported by survey data to explore this issue at one Australian university. The survey indicated that the majority of students are effectively excluded from the university's Student Exchange Programme, and that those included generally have high cultural, social and economic capital. Interviews revealed how multiple dimensions of privilege typically work to make study abroad imaginable, affordable and do-able for some. These findings are complicated by one student's atypical narrative, which serves to raise further questions for research.     

Challenges and policies for promoting internationalization—The case of Iranian public universities

The global knowledge economy has turned higher education into a key player in societal development. Internationalization benefits higher education institutions in several aspects, such as improvement and visibility in international rankings, revenue generation via tuition fees and external funding, improvement of research and teaching quality, integration with academic communities and familiarization with scholarly attitudes. In this study, we provide insights into the challenges of internationalization faced by higher education institutions in Iran as a developing country. Several policies and practices have been adopted in Iran to improve internationalization efforts; however, these activities have had little impact on the quality of research and educational programs at Iran's universities. Understanding the challenges they face in a systematic way can help identify different factors and develop a set of suggestions to increase the quality and quantity of international cooperation. We formulate our suggestions based on the opportunities provided by the digitalization solutions in the aftermath of the COVID-19 pandemic and the increasing importance of the UN's Sustainable Development Goals in both global and national environments. We interviewed 15 faculty members in Iranian higher education institutions and 14 managers in charge of international affairs at universities in Iran. In addition, data extracted from three forums on Iranian higher education internationalization are analysed. Using a grounded theory approach, we group the challenges into macro-, institutional and individual levels and then suggest a number of practices and policies to increase the quantity and quality of internationalization efforts.     

Substitutability and complementarity of technological knowledge and the inventive performance of semiconductor companies

This paper analyses whether complementarity and substitutability of knowledge elements are key determinants of the firm's inventive performance, in addition to the more conventional measures of knowledge stock and diversity. Using patent data from 1968 to 2002 in the semiconductor industry, we find that the overall level of complementarity between knowledge components positively contributes to firms’ inventive capability, whereas the overall level of substitutability between knowledge components generally has the opposite effect. Yet a relatively high level of substitutability is found to be beneficial for explorative inventions. These results suggest that a firm's inventive capacity significantly depends on its ability to align its inventive strategies and knowledge base structure.
