Engineering students’ experiences of interactive teaching in calculus     

Maria Weurlander  Mikael Cronhjort  Lars Filipsson 《高等教育研究与发展》2017,36(4):852-865

This study reports on an educational development initiative where peer instruction was used instead of traditional lectures in a calculus course for first-year engineering students. The aim of the study was to explore students’ experiences of this method. Data were collected by means of an open-ended questionnaire on two occasions: early and late in the course. The data were analyzed with an inductive content analysis. The findings comprise three qualitatively different ways to experience the interactive teaching method in calculus: (1) enthusiasm, (2) nuanced skepticism and (3) aversion. The categories differed regarding emotional reactions to the teaching, experiences of learning, conceptions of teaching and learning, and experiences of meaningfulness. Many students expressed enthusiasm for learning with peer instruction and noted that the method gave both teachers and students feedback on what students have difficulties with. These students perceived that they were responsible for their own learning. Other students experienced that peer instruction had some advantages and disadvantages, and preferred a mix between traditional lectures and peer instruction sessions. They seemed to believe that teachers and students share responsibility for learning. Some students expressed an aversion for peer instruction and the method seemed to challenge their beliefs of how teaching and learning is best conducted. Our study illustrates that educational development initiatives, even though based on research on student learning, do not benefit all students. One of the major obstacles seems to be that students’ underlying beliefs regarding teaching and learning may be counterproductive to the ideas behind the educational initiative. We suggest that beliefs regarding teaching and learning need to be addressed when introducing new teaching and learning methods.  相似文献   

Are there differences in ethnic majority and minority adolescents’ friendships preferences and social influence with regard to their academic achievement?     

Tobias H. Stark  Lars Leszczensky  Sebastian Pink 《Zeitschrift für Erziehungswissenschaft》2017,20(3):475-498

Research has established that adolescents both befriend peers based on their academic achievement and adjust their own achievement to that of their friends’ over time. However, these processes may be different for ethnic minority students, because some of them may adhere to an oppositional culture that rejects striving for academic success. We examine respective differences between self-identified ethnic minority and majority students using longitudinal social network analysis (stochastic actor-oriented models) in a sample of 1175 students (aged 13) from 12 grade-level networks in Germany secondary schools. Among the students, we find that academically successful students in particular prefer friends with high grades, but that students with poor grades exert more social influence on their friends to adjust their performance. Moreover, while minority students are indeed less inclined to select friends with higher grades, both ethnic majority and minority youth prefer friends with similar academic achievement and are similarly influenced by their friends’ achievement. However, social influence is stronger from same-ethnic than from inter-ethnic friends. In sum, there is mixed evidence for an oppositional culture among ethnic minority students in our sample.  相似文献   

Accelerometer-measured daily physical activity related to aerobic fitness in children and adolescents     

Dencker M  Andersen LB 《Journal of sports sciences》2011,29(9):887-895

Maximum oxygen uptake (VO(2PEAK)) is generally considered to be the best single marker for aerobic fitness. While a positive relationship between daily physical activity and aerobic fitness has been established in adults, the relationship appears less clear in children and adolescents. The purpose of this paper is to summarise recently published data on the relationship between daily physical activity, as measured by accelerometers, and VO(2PEAK) in children and adolescents. A PubMed search was performed on 29 October 2010 to identify relevant articles. Studies were considered relevant if they included measurement of daily physical activity by accelerometry and related to a VO(2PEAK) either measured directly at a maximal exercise test or estimated from maximal power output. A total of nine studies were identified, with a total number of 6116 children and adolescents investigated. Most studies reported a low-to-moderate relationship (r = 0.10-0.45) between objectively measured daily physical activity and VO(2PEAK). No conclusive evidence exists that physical activity of higher intensities are more closely related to VO(2PEAK), than lower intensities.  相似文献   

Reprint of: Social movements and free innovation     

Lars Bo Jeppesen 《Research Policy》2021,50(8):104288

In this article, I explore innovation and diffusion from social movements as part of the phenomenon of free innovation in households. The article contributes to the literature on household innovation by illustrating how social movement motivations may differ from motivations examined in prior studies focused on self-rewards, as well as examining the implications for free innovations and diffusion patterns in this setting. Social movement innovators are typically motivated by a common cause (such as a quest for a new life order and societal change) and create innovations that address a cause and “system change” rather than individual goals. I identify and define three types of social movement innovation: behavioral, product, and symbolic innovation. The common-cause motivation also creates a new form of diffusion problem that can only be solved through the spread and consumption of new products, behaviors, or techniques by a sufficiently large crowd. Common-cause motivations should thus encourage innovation diffusion, thereby reducing the risk of the diffusion-failure problem usually observed in household innovation research.  相似文献   

Not just another evaluation: a comparative study of four educational quality projects at Swedish universities     

Karlsson  Sara  Fogelberg  Karin  Kettis  Åsa  Lindgren  Stefan  Sandoff  Mette  Geschwind  Lars 《Tertiary Education and Management》2014,20(3):239-251

In this study, four recent self-initiated educational quality projects at Swedish universities are compared and analyzed. The article focuses on how the universities have handled the tension between external demands and internal norms. The aim is to contribute to an improved understanding of quality management in contemporary universities. On the one hand, the projects are found to be built on similar rationales associated with accountability, reputation building and strategic management. This is interpreted as a response to the shared external policy context. They are also found to mirror similar ambitions regarding raising the status of education. On the other hand, the projects are found to differ considerably in their actual design, methodology, implementation, stakeholders and outcomes. This is interpreted as an active adaptation to the unique internal academic norms and cultures that exist in each university.  相似文献

Enlightenment and measurement - a way to improve health among high school students     

J Greve  LB Andersen 《Journal of sports sciences》2012,30(12):1199-1205

Abstract This paper examines the effect of participating in a web-based health programme that promotes personal tracking of high school students' own measurements of a number of health-related parameters. Danish cross-sectional survey data were used to examine the effects of the health programme on various health measures. Both quantile regression models and standard ordinary least squares (OLS) models were used to explore the correlations between the students' participation in the health programme and their body mass index (BMI), body fat percentage, aerobic fitness, and well-being. Participation in the health programme increased BMI and aerobic fitness among students with a BMI or an aerobic fitness value ranging from the 25th percentile to the 75th percentile and reduced body fat percentage among students with the highest percentages of body fat. In addition, the health programme led to an increased feeling of wellbeing among students, especially those with high BMI levels and poor aerobic fitness. As the schools participated in the health programme on voluntary basis and at a financial cost to themselves, the positive effects of participation found can only be stated to be valid among students from committed schools.  相似文献   

Coherence in professional education: does it foster dedication and identification?     

Kåre Heggen  Lars Inge Terum 《Teaching in Higher Education》2013,18(6):656-669

This article examines the impact of professional education on students' dedication to and identification with a profession. The premise is that professional education is not only about knowledge acquisition and reasoning but also about attitudes and aspirations. In fostering dedication and identification, students' experiences of relevance seem to be important. The concept of coherence seen as an expression of relevance is introduced and measured by four kinds of interactions: Theory–practice interaction, teacher–student interaction, peer interaction and supervisor–student interaction. Analysis indicates that coherence, particularly as theory–practice interaction, peer interaction and supervisor–student interaction, has a significant impact on dedication to and identification with a profession. Longitudinal survey data – collected from students in colleges for teaching, nursing and social work – are analysed.  相似文献   

Medical teachers' professional development – perceived barriers and opportunities     

Terese Stenfors-Hayes  Maria Weurlander  Lars Owe Dahlgren  Håkan Hult 《Teaching in Higher Education》2013,18(4):399-408

This paper explores medical teachers' perceived barriers and opportunities for educational and professional development. Data has been gathered through 19 semi-structured interviews with participants on a staff development course 1 year after their participation. The analysis shows that most perceived barriers are found on an organisational level, whilst motivation for development is found on an individual level and often related to the notion of teaching as a ‘private business’. However, what some respondents perceive as barriers are by others seen as opportunities. Some of these differences in perception may be explained by self-efficacy beliefs.  相似文献
