摘要
以学习者为中心的学习评价标准从知识转向了能力。把虚拟学习社区作为E-learning学习的平台,基于虚拟学习社区和E-learning学习的特点,结合个人学习能力、学习协作能力以及成绩考核来对社区学习者能力进行模糊综合评价,建立了社区学习者能力模糊综合评价模型,其评价结果是与评语集相对应的隶属度向量。为了解决评价结果模糊度较大的问题,充分利用了综合评判带来的信息,提出并建立了隶属度向量等级量化模型,并对评价结果作进一步量化,达到了进一步准确区分学习者能力的目的。
The assessment standard of the learner-centered teaching evaluation steers from knowledge to ability.Using virtual learning communities as a E-learning platform,a community learners＇ ability fuzzy assessment model was set up,based on the characteristics of virtual learning communities and E-learning,combining personal ability,online coo-peration ability and the test results.The assessment agrees with the membership vector of the comments.To narrow the fuzzy disparity,this paper made use of the information from the comprehensive evaluation to build a classification quantitative model,thus further quantifying the assessment to classify the students＇ ability more accurately.
