Game-Based Learning in Virtual Worlds: A Multiuser Online Game for Medical Undergraduate Radiology Education within Second Life     

Rocio Lorenzo-Alvarez  Teodoro Rudolphi-Solero  Miguel J. Ruiz-Gomez  Francisco Sendra-Portero 《Anatomical sciences education》2020,13(5):602-617

Game-based learning can have a positive impact on medical education, and virtual worlds have great potential for supporting immersive online games. It is necessary to reinforce current medical students' knowledge about radiological anatomy and radiological signs. To meet this need, the objectives of this study were: to design a competition-based game in the virtual world, Second Life and to analyze the students' perceptions of Second Life and the game, as well as to analyze the medium-term retention of knowledge and the potential impact on the final grades. Ninety out of 197 (45.6%) third-year medical students voluntarily participated in an online game based on self-guided presentations and multiple-choice tests over six 6-day stages. Participants and non-participants were invited to perform an evaluation questionnaire about the experience and a post-exposure knowledge test. Participants rated the experience with mean scores equal to or higher than 8.1 on a 10-point scale, highlighting the professor (9.5 ± 1.1; mean ± SD) and the virtual environment (8.9 ± 1.1). Participants had better results in the post-exposure test than non-participants (59.0 ± 13.5 versus 45.3 ± 11.5; P < 0.001) and a lower percentage of answers left blank (6.7 ± 8.4 versus 13.1 ± 12.9; P = 0.014). Competitive game-based learning within Second Life is an effective and well-accepted means of teaching core radiological anatomy and radiological signs content to medical students. The higher medium-term outcomes obtained by participants may indicate effective learning with the game. Additionally, valuable positive perceptions about the game, the educational contents, and the potential benefit for their education were discovered among non-participants.  相似文献   

Sociomaterial movements of students' engagement in a school's makerspace     

Kristiina Kumpulainen  Anu Kajamaa 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(4):1292-1307

This study investigates the sociomaterial movements of student engagement in a school's makerspace. Here, we understand sociomaterial movements as emergent and relational, comprising complex dynamics of agency across students, teachers and materials in situated, culturally framed activities. Our study draws on data comprising 85 hours of video recordings of 9–12-year-old students' (N = 94) engagement in a technology-rich makerspace in a Finnish elementary school. The video data were transcribed and analyzed qualitatively using a multimodal interaction analysis. The sociomaterial movements were found to be displayed across a tension-laden continuum between (1) procedural activity—analysis and reflection; (2) individual activity—collaboration; (3) “doing school”—empowerment; and d) alienation—identification. Together, the study offers a potential approach for investigating and understanding the often overlooked workings of sociomateriality that constitutes students' emergent engagement and learning opportunities in science, technology, engineering and mathematics (STEAM) learning contexts.  相似文献   

Early career mathematics teachers: Concepts,methods, and strategies for comparative international research     

《Teaching and Teacher Education》2020

In this article, we report on the challenges entailed in the development of concepts, methods, and strategies for designing and implementing a cross-national research study of the first-years of school-mathematics teaching, including an exploration of how beginning mathematics teachers differ in their preparation, knowledge for teaching, teaching practice, working conditions, and pupil characteristics. The study was designed as a proof-of-concept for a study of teaching and teacher education to be implemented by educationalists, teacher educators, and early career teachers as an ongoing professional endeavor. Primary among the challenges was the development of the sampling design and the construction of measures.  相似文献   

Priming urban learners' attitudes toward the relevancy of science: A mixed-methods study testing the importance of context     

Phillip A. Boda  Bryan Brown 《科学教学研究杂志》2020,57(4):567-596

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.  相似文献   

我国马拉松跑者深度休闲特质的质性研究     

田海波  周文婷  邱亚君  齐震 《沈阳体育学院学报》2020,(1):54-60

在"马拉松热"的背景下,对跑步参与过程中马拉松跑者的深度休闲特质进行探究。采用滚雪球抽样方式,对20名马拉松跑者进行半结构式访谈,通过质性分析软件NVivo 11.0对访谈资料进行分析。研究结果表明马拉松跑者具有深度休闲的6个特质:坚持不懈、生涯性、显著的个人努力、强烈的认同感、独特的文化、持久的收益。本研究进一步丰富了已有研究成果,其中坚持不懈中的"毅力"和"自我管理"两方面体现了马拉松项目的特点。对马拉松跑者来讲,经济回报和团队发展并不是明显的持久收益。本研究结果拓展了对我国"马拉松热"现象的理解,未来应采用定量方法进行深入研究。  相似文献
