5.2 Implications

Compared with the traditional teaching modes, Jigsaw Ⅳ is a new kind of teachingmethods with unparalleled advantages. For instance, it easy for teachers to master and it can beused with other strategies. But several attentions still should be paid during the implementation. Selection and Division of General TaskIt is necessary to select reading material which is close to the student life or students maybe interested in. It’s also important to choose open topics which are neither too difficult nor tooeasy for the students (Hua, 2007:366).When teacher divide the task, some skills should be noticed. First, the students should beaware of the general tasks and the subtask the Expert Group needs to complete. Second, thenumber of subtasks should be the same as the number of group members. If there are too manystudents in each group, two members in the same home group could be responsible for the samesubtask. Thirdly, make sure the different subtasks are both relatively independent and relational.On one hand, relative independence can make individual have the sense of responsibility andshe/he can not be replaced by others. Meanwhile she/he should realize the team’s learning willbe affected if they do not study hard. On the other hand, interconnection can enable students tounderstand the interdependence, that is to say, each subtask that other person is responsible forhas logical contact with their own subtasks. Therefore listening to the others is beneficial fortheir own learning subtasks. Last but not the least, reasonable division of learning materials alsotakes into account the difficulty of each sub-task and workload balancing. Therefore, the tasksare assigned to the students according to their own ability and the role of the home group toensure that the teaching and learning can go smoothly. Reasonable Division of Home GroupAt present, educators generally agree to comply with the principle of “population balanceand mass balance” when dividing the home groups. That is, the population of each group is nottoo much, nor too few. Four to six members are ideal. However, for forming the home group,there exist three main perspectives in general (Zhang&Li, 2010:76).One view is that the principle of “heterogeneity in the groups and homogeneity betweenthe groups” should be followed. The so-called heterogeneity in the group means that 4 to 6members group have different academic performance, ability, gender, and even personality,family background in the same home group, which helps the students complement each other inthe process of learning(Huang&Ceng,2009:610). This grouping method not only help tocomplement strengths and advantages of the students in the same home group but also balancethe overall level of each group, thus ensure fair competition among the groups. This is agrouping method recognized by most people currently. Nevertheless, there is a certain degree ofdifficulty in classroom management.The second view is to follow the principle of “homogeneity in the groups, heterogeneitybetween groups”. The so-called group homogeneity refers to the students in the same homegroup with similar ability and personality, so as to avoid the situation of “one-man-center”,namely, the student talk in full tone while other students only l本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
