This aim of this research was to investigate art teacher education in Taiwan and England to gain insights into two art education systems with a view to improving art teacher education in Taiwan. To achieve this aim, a cross‐cultural study using a multi‐method approach was adopted and data was collected over three years of full‐time study in England and four academic years of reflection on teaching in art teacher education in Taiwan. This research revealed how complex and hazardous it is to state categorically what the similarities and differences really are between two art teacher education systems, especially in a subject as ill‐defined as art. Nonetheless, this study did produce some important differences in the two art teacher education systems in aspects of (1) government regulations and institutional provision, (2) theoretical underpinning, (3) art curriculum policy and delivery, and (4) cultural differences affecting art teachers' attitudes and values. 相似文献

An interactive videodisc system designed to teach language concepts to deaf students was evaluated in a classroom trial. An experimental group of 18 students spent 60 twenty‐minute sessions over a five‐month period learning language concepts by interacting with the system while a control group of 16 students learned the same concepts in their regular classroom setting. Both groups made significant progress from pre‐ to post‐test on two criterion‐referenced testsdeveloped by project staff. Experimental students were enthusiastic about the videodisc, felt that their language skills had improved, and were anxious to continue working with the system. 相似文献

The interrupted learner: How distractions during live and video lectures influence learning outcomes 下载免费PDF全文
Andrew H. Zureick Jesse Burk‐Rafel Joel A. Purkiss Michael Hortsch 《Anatomical sciences education》2018,11(4):366-376
New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi‐year study of the first‐year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first‐year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in “non‐lecture activities” (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities—whether live or recorded—can have an important impact on learning outcomes.

In educational practice, test results are used for several purposes. However, validity research is especially focused on the validity of summative assessment. This article aimed to provide a general framework for validating formative assessment. The authors applied the argument‐based approach to validation to the context of formative assessment. This resulted in a proposed interpretation and use argument consisting of a score interpretation and a score use. The former involves inferences linking specific task performance to an interpretation of a student's general performance. The latter involves inferences regarding decisions about actions and educational consequences. The validity argument should focus on critical claims regarding score interpretation and score use, since both are critical to the effectiveness of formative assessment. The proposed framework is illustrated by an operational example including a presentation of evidence that can be collected on the basis of the framework. 相似文献
