Appreciation of problem structure is critical to successful learning. Two experiments investigated effective ways of communicating problem structure in a computer-based learning environment and tested whether verbal instruction is necessary to specify solution steps, when deep structure is already embellished by instructional examples. Participants learned to solve algebra-like problems and then solved transfer problems that required adjustment of learned procedures. Experiment 1 demonstrated that verbal instruction helped learning by reducing learners' floundering, but its positive effect disappeared in the transfer. More importantly, students transferred better when they studied with examples that emphasized problem structure rather than solution procedure. Experiment 2 showed that verbal instruction was not necessarily more effective than nonverbal scaffolding to convey problem structure. Final understanding was determined by transparency of problem structure regardless of presence of verbal instruction. However, verbal instruction had a positive impact on learners by having them persist through the task, and optimal instructional choices were likely to differ depending on populations of learners. 相似文献

An Autoethnographical Study of Culture,Power, Identity and Art Education in Post‐Colonial South Korea 下载免费PDF全文
This article reflects my experiences of learning art in the 1970s and 1980s and my teaching career in school art education in twenty‐first century South Korea. This autobiographical reflection shows how I have struggled with my identity as an art teacher in the post‐colonial context of Western influences on Korean society since World War II. There has been greater tension and a greater struggle for different values, practices and identities when new values and practices have been introduced into the particular socio‐cultural context of South Korea. My struggles with particular kinds of pedagogic identity valued within the rapidly changing political, economic and cultural context of Western influences on Korean art education demonstrate the hidden structural mechanism of the relationship between culture, power and identity in the post‐colonial world of globalisation. This study as an autoethnographical research provides critical insights into how identities are produced by pedagogic discourses and practices of art education that are constructed through the specific systems of practice and language which transmit and regulate such identities and values. 相似文献

Soft robotics with new designs, fabrication technologies and control strategies inspired by nature have been totally changing our view on robotics. To fully exploit their potential in practical applications, untethered designs are preferred in implementation. However, hindered by the limited thermal/mechanical performance of soft materials, it has been always challenging for researchers to implement untethered solutions, which generally involve rigid forms of high energy-density power sources or high energy-density processes. A number of insects in nature, such as rove beetles, can gain a burst of kinetic energy from the induced surface-energy gradient on water to return to their familiar habitats, which is generally known as Marangoni propulsion. Inspired by such a behavior, we report the agile untethered mobility of a fully soft robot in liquid based on induced energy gradients and also develop corresponding fabrication and maneuvering strategies. The robot can reach a speed of 5.5 body lengths per second, which is 7-fold more than the best reported, 0.69 (body length per second), in the previous work on untethered soft robots in liquid by far. Further controlling the robots, we demonstrate a soft-robot swarm that can approach a target simultaneously to assure a hit with high accuracy. Without employing any high energy-density power sources or processes, our robot exhibits many attractive merits, such as quietness, no mechanical wear, no thermal fatigue, invisibility and ease of robot fabrication, which may potentially impact many fields in the future. 相似文献

This study focused on the barriers that middle school teachers faced when implementing technology-enhanced problem-based learning (PBL) in their classrooms. Using a human performance-based model, we interviewed teachers, administrators, university faculty and technical support staff to determine the perceived importance of multiple barriers to the implementation of technology-enhanced PBL. Twenty-one teachers, two school administrators and a project manager, two faculty members, and two technical support staff participated in the study. Interview data were supported by surveys, classroom observations and researchers' reflective journals. Results suggested that lack of a clear, shared vision was the primary barrier. Additional barriers included lack of knowledge and skills, unclear expectations and insufficient feedback. Recommendations to support teachers' efforts to integrate technology-enhanced problem-based learning are presented. 相似文献

ABSTRACT The need for longitudinal and holistic support of medical students throughout their training has led to the development of formal mentoring programs. Whilst success of formal mentoring programs has been attributed to (a) pairing mentees with trained and experienced mentors (matching), (b) the quality of mentoring interactions and (c) the presence of a nurturing environment, little attention has been attributed to establishing an effective matching process in medical school. We sought, in this review, to redress this gap within the context of matching medical students for mentoring. Modified PRISMA guidelines were followed to guide the review process. PubMed, ERIC, Cochrane Database, OVID and ScienceDirect databases were searched for articles on matching in medical schools and in allied health specialities published between 2000 and 2015. 相似文献
