作业社会化批阅工具的设计、开发与评估

Design,Development,and Evaluation of Homework Social Review Tool

传统教学中作业批阅以全批全改和精批细改为主,造成了教师批阅压力大、作业反馈不即时、评价结果缺乏针对性、不利于开展过程性评价问题。自评、同伴互评一定程度能减轻教师批阅压力,但质量不能保证。本研究针对上述问题,提出了作业社会化批阅方法,将作业批阅权限公开化,充分利用社会化批阅专家、家长、学生的力量和社会化批阅系统中内置的批阅可信度保障模型,在保证作业批阅结果准确性基础上,降低教师的批阅压力、促进作业反馈的即时性、个性化,进而推动作业过程性评价和学生学习效率提升。在社会化批阅理念指导下本研究访谈了教师作业批阅需求,并基于学习元平台设计和开发了作业的社会化批阅系统并选取了PPT的使用课程进行实验,结果表明,作业进行访谈社会化批阅系统具有较好的实用性和易用性,其批阅结果也与教师批阅结果存在较大一致性,从而验证了作业社会化批阅方法具备实践价值。

Traditionally, it is always the teacher who conducts homework review carefully one after another. In some aspects, this condition leads to teachers＇ high pressure. Moreover, due to the high quantity of homework for teachers＇ to review, reasonable feedbacks get delayed while the quality of them becomes lower. As a result, the evalua- tion does little to benefit learning and the development of instruction. Self-evaluation and peer review can help improve the condition, but they not guarantee the quality of the evaluation while increasing students＇ stress. Social review makes homework review an open, social activity for all social members including teachers, experts, parents and even students with the help of the auto quality guarantee mechanism created by the social review system. All social members can participate in the process of homework review if they are certificated in the system. And with the help of social re- viewers, teachers become more relaxed and the feedback becomes more timely, individual and process oriented. This will finally benefit homework evaluation and students＇ learning. In this study, the researchers investigated teachers＇ needs and developed a social review system based on Lcell platform and conducted an experiment to verify the result of the system. The result demonstrats that the social review system provides practical value and is authoritative. It can be helpful in educational practice.
