Building Your Licensing and Negotiation Skills Toolkit     

Claire Dygert  Robert Van Rennes 《期刊图书馆员》2015,68(1-4):17-25

Licensing and the negotiating of electronic resources can be a daunting task for librarians who lack the proper skill sets and are unfamiliar with the intricacies of publisher agreements. Claire Dygert broke down the individual elements of a standard licensing agreement and explained the importance of protecting the rights of libraries. By providing insight from her years of experience, librarians learned how to develop a support network, build confidence, and be more effective negotiators.  相似文献   

Priming and Fake News: The Effects of Elite Discourse on Evaluations of News Media     

Emily Van Duyn  Jessica Collier 《Mass Communication and Society》2019,22(1):29-48

Fake news has become a prominent topic of public discussion, particularly among elites. Recent research has explored the prevalence of fake news during the 2016 election cycle and possible effects on electoral outcomes. This scholarship has not yet considered how elite discourse surrounding fake news may influence individual perceptions of real news. Through an experiment, this study explores the effects of elite discourse about fake news on the public’s evaluation of news media. Results show that exposure to elite discourse about fake news leads to lower levels of trust in media and less accurate identification of real news. Therefore, frequent discussion of fake news may affect whether individuals trust news media and the standards with which they evaluate it. This discourse may also prompt the dissemination of false information, particularly when fake news is discussed by elites without context and caution.  相似文献   

Modeling Growth in Electronic Learning Environments Using a Longitudinal Random Item Response Model     

Damazo T. Kadengye  Eva Ceulemans  Wim Van Den Noortgate 《Journal of Experimental Education》2015,83(2):175-202

In educational environments, monitoring persons' progress over time may help teachers to evaluate the effectiveness of their teaching procedures. Electronic learning environments are increasingly being used as part of formal education and resulting datasets can be used to understand and to improve the environment. This study presents longitudinal models based on the item response theory (IRT) for measuring persons' ability within and between study sessions in data from web-based learning environments. Two empirical examples are used to illustrate the presented models. Results show that by incorporating time spent within- and between-study sessions into an IRT model; one is able to track changes in ability of a population of persons or for groups of persons at any time of the learning process.  相似文献   

Estimation of a Nonlinear Intervention Phase Trajectory for Multiple-Baseline Design Data     

Ian Hembry  Rommel Bunuan  John M. Ferron  Wim Van den Noortgate 《Journal of Experimental Education》2015,83(4):514-546

A multilevel logistic model for estimating a nonlinear trajectory in a multiple-baseline design is introduced. The model is applied to data from a real multiple-baseline design study to demonstrate interpretation of relevant parameters. A simple change-in-levels (ΔLevels) model and a model involving a quadratic function (Quadratic) for the nonlinear intervention phase data were also estimated. In addition, a simulation study was conducted to assess Markov chain Monte Carlo estimation of the logistic model and compare its trajectory recovery with use of the ΔLevels and Quadratic models. While most of the logistic model's parameter values were recovered well, trajectory recovery was very reasonable using the simpler Quadratic model. Results are discussed along with recommendations for practitioners and directions for future research.  相似文献   

Endorsing achievement goals exacerbates the big-fish-little-pond effect on academic self-concept     

Sofie Wouters  Hilde Colpin  Jan Van Damme  Karine Verschueren 《教育心理学》2015,35(2):252-270

The big-fish-little-pond effect (BFLPE) model predicts students’ academic self-concept to be negatively predicted by the achievement level of their reference group, controlling for individual achievement. Despite an abundance of empirical evidence supporting the BFLPE, there have been relatively few studies searching for possible moderators. Integrating the BFLPE model with Achievement Goal Theory, the present study aims to determine whether the negative effect of class-average achievement on academic self-concept is moderated by individual and class-average achievement goals. Our sample comprised of 2987 students (50% boys) from Grade 6 in 112 elementary schools in the Flemish region of Belgium (174 classes). Applying multilevel modelling, we found a stronger BFLPE when students’ individual achievement goals were higher, regardless of the specific nature of these goals. The BFLPE was not moderated by class-average levels of achievement goals. Overall, our findings demonstrate that the BFLPE is moderated by individual goal-related factors.  相似文献   

Social capital in the classroom: a study of in-class social capital and school adjustment     

Ronan Van Rossem  Marjolijn Vermande  Beate Völker  Chris Baerveldt 《British Journal of Sociology of Education》2015,36(5):669-688

Social capital is generally considered beneficial for students’ school adjustment. This paper argues that social relationships among pupils generate social capital at both the individual and the class levels, and that each has its unique effect on pupils’ performance and well-being. The sample in this study consists of 1036 children in 60 first-grade classes in 46 Dutch elementary schools. Multilevel regression results show that a substantial proportion of the variance in school adjustment can be attributed to the class level and that both individual-level and classroom-level social capital have substantial effects on school adjustment. At the individual level, the size of one’s network is more important than its structure. At the collective level, social capital also has a ‘dark side’ because it can have negative effects on adjustment, lowering the academic performance in a class.  相似文献   

Design and implementation of multi-campus,modular master classes in biochemical engineering     

Niek Wuyts  Dorine Bruneel  Myriam Meyers  Etienne Van Hoof  Leander De Vos  Greet Langie 《European Journal of Engineering Education》2015,40(4):400-409

The Master of Science in engineering technology: biochemical engineering is organised in KU Leuven at four geographically dispersed campuses. To sustain the Master's programmes at all campuses, it is clear that a unique education profile at each campus is crucial. In addition, a rationalisation is required by increased cooperation, increased exchange of lecturers, and increased student mobility. To achieve this, a multicampus education system for the M.Sc. in engineering technology: biochemical engineering was developed by offering modules that are also available for students of other campuses. Such a module is primarily based on the research expertise present at the campus. In the development, special attention has been given to the optimal organisation of the modules, evaluation, required modifications of the current curricula, and the practical consequences for students following the module at another campus. Even in the first year of implementation, around 30% of the students followed a multicampus module, which indicates the potential success of the multicampus concept described here.  相似文献   

Using methodological triangulation to examine the effectiveness of a mentoring program for online instructors     

Michelle Drouin  Jennifer Stewart  Karen Van Gorder 《Distance Education》2015,36(3):400-418

In this quasi-experimental mixed methods study, we examined the effectiveness of a faculty-to-faculty mentoring program to increase student success rates in online courses at an American university. Over one semester, 24 faculty mentees worked with 6 faculty mentors on improving course organization and implementing student engagement techniques. Using methodological triangulation, we found positive results for two of our effectiveness measures (i.e., mentor and mentee feedback and mentors’ ratings of mentees’ courses). However, in terms of our third measure (i.e., student learning data), although institutional data showed that there was a 4.1% aggregate increase in online student success after the intervention, the intervention group made no significantly greater gains than two control groups. Our findings highlight some benefits and shortcomings of these types of university initiatives and also emphasize the importance of using triangulation to integrate participant feedback with formal measures of student success.  相似文献
