Automatic item generation of probability word problems     

Heinz Holling  Jonas P. Bertling  Nina Zeuch 《Studies in Educational Evaluation》2009,35(2-3):71-76

Mathematical word problems represent a common item format for assessing student competencies. Automatic item generation (AIG) is an effective way of constructing many items with predictable difficulties, based on a set of predefined task parameters. The current study presents a framework for the automatic generation of probability word problems based on templates that allow for the generation of word problems involving different topics from probability theory. It was tested in a pilot study with N = 146 German university students. The items show a good fit to the Rasch model. Item difficulties can be explained by the Linear Logistic Test Model (LLTM) and by the random-effects LLTM. The practical implications of these findings for future test development in the assessment of probability competencies are also discussed.  相似文献

Research to Practice: Observing Learning in Tinkering Activities     

Joshua P. Gutwill  Nina Hido  Lisa Sindorf 《Curator: The Museum Journal》2015,58(2):151-168

As tinkering and making spaces proliferate in museums, many researchers, practitioners, funders, and policy‐makers seek to understand what constitutes learning‐through‐tinkering. To support discussion of tinkering‐based learning, the Exploratorium sought to articulate and refine a valid, evidence‐based definition of learning in its permanent on‐floor Tinkering Studio. We studied and made videos of fifty learners and their companions in one of three tinkering activities in the Tinkering Studio. A team of researchers and practitioners used the videos to refine frameworks for learning and facilitation (initially developed in a prior project), leading to the identification of four Dimensions of Learning and three broad Facilitation Moves. We created a Tinkering Library of Exemplars that categorizes over one hundred video clips according to these frameworks. The Library may help articulate important aspects of learning and facilitation, give voice to practitioners’ values in defining learning‐through‐tinkering, and lay a methodological foundation for gathering evidence for such learning. The Library is available for download.  相似文献   

Science and Language Teachers’ Assessment of Upper Secondary Students’ Socioscientific Argumentation     

Nina Christenson  Niklas Gericke  Shu-Nu Chang Rundgren 《International Journal of Science and Mathematics Education》2017,15(8):1403-1422

Researchers and policy-makers have recognized the importance of including and promoting socioscientific argumentation in science education worldwide. The Swedish curriculum focuses more than ever on socioscientific issues (SSI) as well. However, teaching socioscientific argumentation is not an easy task for science teachers and one of the more distinguished difficulties is the assessment of students’ performance. In this study, we investigate and compare how science and Swedish language teachers, participating in an SSI-driven project, assessed students’ written argumentation about global warming. Swedish language teachers have a long history of teaching and assessing argumentation and therefore it was of interest to identify possible gaps between the two groups of teachers’ assessment practices. The results showed that the science teachers focused on students’ content knowledge within their subjects, whereas the Swedish language teachers included students’ abilities to select and use content knowledge from reliable reference resources, the structure of the argumentation and the form of language used. Since the Swedish language teachers’ assessment correlated more with previous research about quality in socioscientific argumentation, we suggest that a closer co-operation between the two groups could be beneficial in terms of enhancing the quality of assessment. Moreover, SSI teaching and learning as well as assessment of socioscientific argumentation ought to be included in teacher training programs for both pre- and in-service science teachers.  相似文献   

Enterprise information asset management: the roles and responsibilities of executive boards     

Nina?EvansEmail author  James?Price 《知识管理研究与实践》2016,14(3):353-361

In the modern organisation the effective management of data, information, content and knowledge is crucial for enhancing competitiveness and growth. There is a profound need for all levels of business management to understand the risks, challenges and business benefit of managing these ‘Information Assets’. This paper describes the results of qualitative empirical research to investigate the roles and responsibilities of Executive Boards to ensure effective management and governance of Information Assets. Personal interviews were conducted with Board members in Australia and the United States. The results indicated that Boards often fail to fully appreciate the strategic value of Information Assets and do not understand the organisational risk and untapped business benefit resulting from ineffective Information Asset Management practices. This paper suggests that Executive Boards should be engaged in discussions about Information Management and fulfil strategic-, control- and institutional roles to guide the way Information Assets are managed and deployed.  相似文献   

Effects of acoustic feedback training in elite-standard Para-Rowing     

Nina Schaffert  Klaus Mattes 《Journal of sports sciences》2015,33(4):411-418

Assessment and feedback devices have been regularly used in technique training in high-performance sports. Biomechanical analysis is mainly visually based and so can exclude athletes with visual impairments. The aim of this study was to examine the effects of auditory feedback on mean boat speed during on-water training of visually impaired athletes. The German National Para-Rowing team (six athletes, mean ± s, age 34.8 ± 10.6 years, body mass 76.5 ± 13.5 kg, stature 179.3 ± 8.6 cm) participated in the study. Kinematics included boat acceleration and distance travelled, collected with Sofirow at two intensities of training. The boat acceleration-time traces were converted online into acoustic feedback and presented via speakers during rowing (sections with and without alternately). Repeated-measures within-participant factorial ANOVA showed greater boat speed with acoustic feedback than baseline (0.08 ± 0.01 m·s^?1). The time structure of rowing cycles was improved (extended time of positive acceleration). Questioning of athletes showed acoustic feedback to be a supportive training aid as it provided important functional information about the boat motion independent of vision. It gave access for visually impaired athletes to biomechanical analysis via auditory information. The concept for adaptive athletes has been successfully integrated into the preparation for the Para-Rowing World Championships and Paralympics.  相似文献   

Do siblings influence one another? Unpacking processes that occur during sibling conflict     

Sahar Borairi  Andre Plamondon  Michelle Rodrigues  Nina Sokolovic  Michal Perlman  Jennifer Jenkins 《Child development》2023,94(1):110-125

This study examined the extent to which 205 sibling dyads influenced each other during conflict. Data were collected between 2013 to 2015. The sample included 5.9% Black, 15.1% South Asian, 15.1% East Asian, and 63.8% White children. Older siblings were between 7–13 years old (Female = 109) and younger siblings were 5–9 years old (Female = 99). Siblings' conflict resolution was analyzed using dynamic structural equation modeling. Modeling fluctuations in moment-to-moment data (20-s intervals) allowed for a close approximation of causal influence. Older and younger siblings were found to influence one another. Younger sisters were more constructive than younger brothers, especially in sister–sister dyads. Sibling age gap predicted inertia in older siblings. Socialization processes within sibling relationships are discussed.  相似文献
