基于多问题学习的慕课体系及其潜在优势分析

慕课这种新型授课方式的主要优势在于其能够让数量众多的学生在相关的信息化平台上反复观看教师所制作的电子课件,让学生能够在潜移默化中寻找到真正适合自己的学习方式,也能够让学生在实际生活中逐渐养成学习的良好习惯。这对于一个学生的未来发展而言是极为重要的。慕课内容的展现方式和制作手段和传统的课堂授课模式存在着明显的差异性。授课教师在决定授课内容的时候需要考虑到教材中的各种知识点核心内涵。在制作慕课课件的时候经常需要将教材中的各种重点内容进行精细化处理,让知识能够具备碎片化的特点,这样,学生在学习某些知识的时候会更加具有针对性,学生对于每个单元知识的重点内容能够把握得更加牢靠。同时,慕课持续的时间也是较为短暂的,一般情况下不会超过15分钟,完全符合心理学的主要规律。教师在制订教学计划的时候一定要提前和本班学生进行多方面的讨论,根据学生的实际需要制定更加切实可行的教学方案,教师需要让学生成为课堂的主人。

A Method for Risky Multiple Attribute Decision Making with Four - dimensional Reference Point

A method based on cumulative prospect theory was proposed to solve risky multiple attribute decision making problems with Four -dimensional reference points. Considering the influence of different learning processes and corresponding features on decision-making, a new reference-learning behavior is added, and a risk-based multiple-attribute decision-making method based on four-dimensional reference point cumulative prospect theory is proposed. Firstly, according to the cumulative prospect theory, the prospect value and the decision function value of the four reference points of learning, time, evaluation value and expected value are calculated respectively, and the cumulative prospect value matrix of each program dynamic is formed. Secondly,according to the WAA operalor, Maximize the stage weighting model to obtain the integrated cumulative prospect value. Finally, on the basis of this, the alternatives are sorted according to the size of the total cumulative prospect value, and compared with other methods, the validity and scientific of the proposed method are proved.
