Idea generation in biomedical engineering courses using Design Heuristics     

Jin Woo Lee  Anastasia Ostrowski  Aileen Huang-Saad  Colleen M. Seifert 《European Journal of Engineering Education》2019,44(3):360-378

ABSTRACT

With increasing demand for improved medical equipment and healthcare, next-generation biomedical engineers need strong design skills. Equipping biomedical engineering students with tools for idea generation and development can increase student design success. Design Heuristics are an ideation tool developed through empirical studies of product designs. While identified in the mechanical engineering space, Design Heuristics may be applicable in biomedical engineering design. In our study, we implemented a Design Heuristics session during upper-level undergraduate and first-year graduate biomedical engineering design courses. We examined the applicability of Design Heuristics within individual and team concept generation contexts. The findings demonstrated that biomedical engineering students were able to use Design Heuristics to generate multiple concepts, and that initial concepts produced using Design Heuristics were carried over into final team design. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design.  相似文献   

指向武术核心素养的中小学武术有效教学策略与方法设计     

柴广新  孙有平 《武汉体育学院学报》2020,54(4):87-92

为了有效促进学生武术核心素养的培育,针对我国武术教学中存在套路内容“繁难”、教法单一、重“形”轻“击”、重知识灌输,轻自主性培养、重教师的“教”,轻学生的“学”“学生不喜欢武术课”等一系列问题,提出了有效促进武术认知、武术运动能力、武术人格培育的原则,基于此原则,对“化难为易”策略、“化浅为深”策略、“化无趣为有趣”策略、“化技术为实践”策略、“知新温故”等策略进行了具体探索性设计,并对上述策略的具体实施方法进行了阐述,为中小学武术教学改革提供现实指导。  相似文献   

Paternal support for child sexual abuse victims: A qualitative study     

《Child abuse & neglect》2019

BackgroundThe current state of knowledge regarding the role of non-offending fathers in supporting their sexually abused children is very scarce.ObjectiveThe objective of this study is to further our understanding of fathers’ roles following disclosure of their children’s sexual abuse (SA) by evaluating fathers’ perceptions of the impact of disclosure on their involvement and support of their children.Participants and methodThis qualitative study relies on individual semi-structured interviews conducted with 17 fathers of allegedly abused children.ResultsInductive thematic analysis first highlighted that some reported a period of disengagement from the child during which they put into question their role and attitudes, followed by a period of re-involvement. This period of difficulties experienced by some fathers in regard to their involvement towards their children was due to either their own important psychological distress, their ambivalence towards their child or even because of feelings of uneasiness experienced during physical contact with them. Despite this, findings indicate the presence of thoughts and attitudes that suggest children are a source of concern for fathers. The four forms of abuse-specific support previously observed among mothers (believing the child, seeking out professional services, protecting him/her from the offender, supporting him/her emotionally) were also observed among fathers. In accordance with the activation theory, a form of support specific to fathers, namely, encouraging the child to open up to and explore the world outside the family, thereby, fostering the child’s self-esteem development, was observed and constitutes a relevant finding.ConclusionClinical and empirical implications are discussed.  相似文献

A qualitative investigation of design knowledge reuse in project-based mechanical design courses     

Dónal P. Holland  Conor J. Walsh 《European Journal of Engineering Education》2019,44(1-2):137-152

ABSTRACT

The interpretation and reuse of previous design solutions, or precedents, is central to design. This paper describes qualitative research conducted over three years at two institutions, aimed at investigating the role of design knowledge re-use in project-based mechanical design courses. Research data were collected through participant observation, student interviews, anonymous questionnaires, and website analytics. The paper identifies challenges that must be addressed in order to support novice engineers in rehearsing the types of knowledge required to successfully reason about and engage with design precedents. Two categories of design precedents are identified: concept precedents and detail precedents. Providing students with access to the latter is identified as a particular challenge, as is providing students with access to engineering communities of practice. Approaches to addressing these challenges are discussed.  相似文献   

Data Visualization as Participatory Research: A Model for Digital Collections to Inspire User-Driven Research     

A. Miller 《Journal of Web Librarianship》2019,13(2):127-155

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies.  相似文献   

线上线下混合式教学模式在“药物分析”教学中的应用探索

线上线下混合式教学是传统教学和信息化教学相结合的一种新型教学模式,它克服了传统教学“满堂灌”的现象,能够调动学生学习的积极性、主动性和创造性,受到教育工作者的广泛关注。本文从线上线下混合式教学的设计与组织、教学过程的质量监控、教学评价体系的构建和教学反思四个方面探索了线上线下混合式教学模式在“药物分析”教学中的应用与实践,为高职院校线上线下混合式教学的应用提供思路。  相似文献   

The impact of student misconceptions on student persistence in a MOOC     

Chen Chen  Gerhard Sonnert  Philip M. Sadler  Dimitar Sasselov  Colin Fredericks 《科学教学研究杂志》2020,57(6):879-910

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献
