这是给我们讲授“程与教学设计”的Prof. Francis Yu(喻潜安教授)布置写的一篇作业,题目是Advantages and disadvantages of generative and supplantive strategies。
【2009年12月27日补记:今天再次阅读我本科的时候写的这篇作业,发现真的很难理解我当时的想法,有很多语法错误,并且观点没有说服力,论证也不足。真的不相信,这就是我以前写的文章。】

1. Generative Strategies

 

      (1) Advantages:

 

*     More interesting and engaging.

Generative strategies tend to result in the bonus learning of cognitive strategies, may often be more interesting and engaging, which really depends on so many other factors, but it’s one of the widely accepted benefits of using learner centered, inquiry, learning environments, and other relatively generative orientations.



*     More deeply processing.

Generative strategies requires learners to relate more information to their own cognitive structure, while Constructivism considers that in this case, learners’ personal interpretation of knowledge becomes evident and learning appears. That is, generative strategies provide more experience for learner that is much significant for learning, for learning is an active process in which meaning is developed on the basis of experience. So learners receive more chance to process under such strategies, which results in better learning.



*     More highly motivation.

Placing learners in an autonomous situation, they may pursue their own specific interests regarding the content. In this case, learners are more motivated to reach their learning goals quickly or to set higher goals appropriate for them.

 

(2) Disadvantages:

 

*    Requiring too much time.

To generate learning by themselves, learners are to take much time to work in their cognitive world. Generative strategies should provide them much time so that they can finish the process. But this may result in retardarce of teaching procedure.



*    Hard to master for teachers

Generative strategies result in more variation of learning outcome among learners and teachers have to analyze all of if. The question is that teachers are not easy to assess the outcome and then response in a short time. In fact, teachers may ignore some unconspicuous outcome from learners.

 

*    More difficult for beginning learners.

Generative strategies place high cognitive demand on learners’ working memory, particularly for less knowledgeable learners, which leads to cognitive overload and emotional frustration.



 

2. Supplantive Strategies

 

    (1) Advantages:

 

*     More efficient.

Supplantive strategies tend to take less time and result in more consistency between learners as to what is learned, provide needed help for beginning learners in a domain, and supply assistance in finding and using appropriate cognitive strategies. Learners will receive evident learning effect in a short time.



*     Good performance in exam

Supplantive strategies provide learners clear way about the exam they will have, and they will prepare much in specific area of the course.

 

(2) Disadvantages:

 

*     Less engaging.

Supplantive strategies engage fewer of the learners’ mental processes, leading to learners’ less completing the learning goals and becoming lazy.



*     Less personal meaningful learning.

Supplantive strategies provide less chance for learners to construct knowledge and to make up their own thoughts. As a result, knowledge is more forgettable and new ideas hardly appears among the course.
