Scaffolding strategies in a rubric-based intervention to promote engineering students’ ability to address wicked problems

ABSTRACT

In recent years, there has been increasing interest within the engineering education research community to prepare engineering students to address wicked problems (WPs) such as climate change, resource scarcity and violent conflict. Previous research suggests that engineering students are able to address WPs if they are given adequate support, but there is a lack of research on what kinds of support are needed. This paper aims to reduce this gap by reporting on students’ performance in, and approaches to, addressing WPs when different scaffolding strategies were used in different parts of a rubric-based intervention. The intervention aimed to provide undergraduate engineering students with an understanding of the nature of WPs and with a structured way of addressing them. For each part of the intervention, we discuss affordances for learning provided by the different scaffolding strategies. The results suggest that strong cognitive scaffolding can support students’ understanding of the nature of WPs and students’ performance in written responses to WPs, but possibly also limits deep engagement with WPs and transfer of learning to other contexts.     

How do tutors use data to support their students?

ABSTRACT

Despite widespread enthusiasm, evidence of the effectiveness of learning analytics remains mixed. One possible explanation for this is that insufficient attention has been paid to the contexts in which it is introduced. We report here on a small-scale study into the prior use of data and communications technologies by tutors, who comprise a key user group in The Open University’s tuition model. Tutors interviewed reported using a complex set of data sources and information tools, and creating local/personal tools and methods for keeping track of students and their interactions with them.     

Drawing on the Past: Reflecting on the Future

This paper examines the connections between the training models of late 19th century Schools of Design (Art) as exemplified by the first municipal School of Art (Margaret Street, Birmingham) and the current preparation of specialist teachers of Art and Design. A recurrent theme is the paradox of objective, measurable standards, pitted against notions of subjective independent learning, individual relevance and choice. Consistent with other papers from this author, the thrust of the perspective is questioning the compatibility of an examination–dominated agenda and opportunities for experimentation, creative risk taking and forms of supported, purposeful play. Continuing research explores the concept and purpose of drawing in an increasingly technological, global information society.     

Evidence for the role of higher order reasoning processes in cue competition and other learning phenomena

When people judge the contingency between a target cue and an outcome, they also take into account the contingency between the outcome and other cues with which the target cue co-occurred. Several authors have argued that such cue competition effects are due to higher order reasoning processes. We review the evidence that supports this hypothesis and discuss whether higher order reasoning might also play a role in other learning phenomena.     

Teaching Basic Science and Clinical Medicine at a distance: An Evaluation of Satellite Communication

The evaluation plan arid preliminary results are reported for the ATS‐6 Satellite interactive telecommunication program for teaching at sites remote from an established medical school. The technical aspects of the system were seen as quite adequate and did not appear to substantially inhibit interaction. In the Fairbanks broadcasts analyzed, the average number of interactions ranged from 1.49 to 2.60 per minute. Ninety percent of the interaction flowed across the Satellite during Omak transmissions. Participants tended to initiate communication when they were on camera rather than when viewing their counterparts. Omak participants directed a higher percentage of the communication in student/resident programs (70%) than in faculty continuing education programs (59%). Interaction analysis indicated the categories of giving opinion, information, and suggestion were most frequent. Asking for opinion and suggestion occurred infrequently. The most frequent emotional expression was offering solidarity (e.g., reassurance), while there were exceedingly few expressions of disagreement, tension and antagonism. User acceptance of the system was determined to be very high. Participants with frequent exposure to the Satellite modality tended to have positive reaction. A significant difference in knowledge gain is reported in one of two basic science areas taught via Satellite as compared to regular instruction.     

“Science of the singular”: an explanatory single case study of whole school guidance counselling in Ireland

This article will discuss the findings of a single explanatory case study on the model of whole school guidance counselling in the Irish secondary school system, which was carried out during a turbulent period of policy and practice changes in the delivery of guidance counselling services to students from 2012 onwards. Although the case study is positioned within a single voluntary school, the findings may be typical of similar secondary schools settings in Ireland and abroad. Particular focus is given to explicating the key findings of the case study through the specific themes of: concepts of whole school guidance counselling, the Irish integrated model of guidance counselling, stakeholder roles and responsibilities, and the effect of resource re-allocations by policy makers funding guidance school services.     

Can narrative cutscenes improve home learning from a math game? An experimental study with children

Little is known about the instructional effects of narrative framing elements in child learning games. In this study, second and third graders (M_age = 8.24) played one of two versions of a successful, commercial mathematical learning game at home for 2 weeks (N = 95; between-subject design). The versions differed in the presence/absence of a background story conveyed through comic cutscenes at the beginning and the end of the game. Results showed that children played the game intensively in both conditions: despite not being forced to do so. Plus, they also learned from the game. As expected, children assigned to the cutscenes condition interfaced with the cutscenes. However, no between-group difference was detected in pre-post learning gains, parent-reported engagement, self-reported enjoyment, time spent with the game and the number of solved in-game tasks (all |ds| < 0.29). Altogether, no advantage or disadvantage from the narrative comic cutscenes was revealed.     

解决分布式需求的内在冲突

2006年8月,GEN(I网络创新的全球化环境)项目组公布其项目的设计原则。来自普林斯顿大学、麻省理工大学、华盛顿大学等学校的十二位专家编写了这份报告。该报告阐述了GENI的研究范围、用户的需求、需求的内在压力,以及工程设计的原则。报告指出了GENI的价值主张,广泛的部署、多样化可扩展的网络技术集合、对真实用户流量的支持仍是GENI关注的原则和方向。上期已经介绍第一部分——“分布式需求定义GENI的重心”,本期刊出第二部分——“解决分布式需求的内在冲突”。
