网络环境下大学英语异步教学评测体系的建立

网络环境中,大学英语异步交互教学模式的建立要求有与之相适应的评价体系加以评价以保证学生的学习效果。对话理论、建构主义和多元智能理论的学习观和评价观为网络环境下大学异步交互学习模式的同步评价体系提供了有力的理论支撑。传统的评价模式多采用课堂评价加上网络自主学习评价体系,其局限性对学生的学习评价缺乏实质上的公允。网络环境中网辅教学和课堂教学相结合的多元多方位的异步评价体系将极大地鼓励学生的参与性、积极性和主观性。

Evolving strategies in whirlwind mode: The changing face of anatomy education during Covid-19 pandemic

The Covid-19 pandemic stipulated adoption of unfamiliar strategies for delivering anatomy education in online mode. The factors which determine education strategies are variable across geographical regions. It was perceived that an overview of education strategies around the globe would be useful for anatomists. Hence this narrative review was undertaken to collate observations from different geographical regions pertaining to education strategies adopted during the pandemic. Data relevant to the topic of study were extracted from 12 articles that were selected from an initial pool of 317 articles based on search criteria set for the review. Subtle differences in core education strategies implied that baseline response from anatomists was similar across regions. It was evident that online digital tools were key elements of education strategies adopted by educators for delivering online anatomy classes across the globe. Interestingly, a considerable gap in terms of number and variety of online tools used for anatomy education (those requiring commercial purchase) was noted between economically developed and developing regions. This may have an impact on learning outcome for students and may even lead to variations in anatomical knowledge by regions. It was observed that offline human dissection sessions were incorporated into online practical classes in one region as positive cases showed a declining trend. This positive development is worth emulating elsewhere based on cautious assessment of prevailing situation. From a broad perspective timely introduction of education strategies ensured delivery of anatomy education during the pandemic and gave an evolved outlook to the fabric of anatomy education.
