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   

Manipulating cognitive engagement in preparation-to-collaborate tasks and the effects on learning     

《Learning and Instruction》2017

While collaborating with a peer can be highly beneficial for learning, more work is needed to understand how instructional activities in collaborative contexts should be designed so as to maximize learning outcomes. To address this, we investigated the impact of different types of preparatory and cognitively engaging tasks on learning from collaborating, using a 2 × 2 experimental study conducted in situ in four introductory psychology classes. We compared individual preparation versus no-preparation and “active” versus “constructive” tasks. A dyadic multilevel analysis showed that preparation prior to collaborating led to better deep learning outcomes, but that the type of preparation did not have a significant effect. We include an exploratory analysis of student dialogues during collaboration to further interpret our findings. We propose that a cognitively engaging preparation phase may lead to better learning because it encourages students to collaborate constructively even when the type of task does not elicit such engagement.  相似文献

The constraints of youth: young people,active citizenship and the experience of marginalisation     

Andrew Hickey  Tanya Pauli-Myler 《Discourse: Studies in the Cultural Politics of Education》2019,40(3):372-385

ABSTRACT

This paper charts the experiences of a group of young people and their involvement in a local government initiative to engage young people in public decision-making. Activated through a youth leaders’ council that sought to influence and inform local government decision-making, the participating young people were given responsibility for enacting focus projects in collaboration with local government personnel. However, this method of simply bringing young people together with local government decision-makers did not automatically alter the way that decisions came to be made and ironically resulted in interactions that went some way to further reinforce existing perceptions of young people as incapable in situations of public administration. This paper reports on a case example detailing an interaction between the youth leaders and local government councillors, and will suggest that the experience of the young people involved in the youth leaders’ council can be understood against a dynamic of ‘constraint’.  相似文献

Study on the distribution of active centers in novel low Ti-loading MgCl2-supported Ziegler-Natta catalyst     

王剑峰  王立  赵振荣  王文钦  陈涛 《浙江大学学报(A卷英文版)》2004,5(8)

Novel MgCl2-supported Ziegler-Natta (Z-N) catalysts prepared using a new one-pot ball milling method caneffectively control the amounts of Ti-loading in the catalysts. Complex GPC data on polypropylene synthesized by thesenovel catalysts were analyzed using the method of fitting the molecular weight distribution (MWD) curves with a multipleFlory-Schulz function. It was found that multiple active centers exist in these novel catalysts. Detailed study of the effects ofthe Ti-loadings in the catalysts on the distribution of the active centers showed that the Ti-loadings in the novelMgCl2-supported Z-N catalysts might affect the proportion of each type of active centers; and might be the main factorresponsible for the effect of the Ti-loadings on the microstructure, the molecular weight and molecular weight distributionwidth of the resultant polymer, the catalytic activity and polymerization kinetics.  相似文献
