Text 2

Read the passage and answer the question.
Numerous studies show that ____________________ as compared to working independently, results in deeper information processing and more meaningful psychological connections among the participants (Johnson, Johnson, and Smith 1998; Smith 1995). The goal of collaboration is to create new insights during discussions (Henry 1992; Kaye 1992) and to move students to an understanding of alternative perspectives (Cunningham 1992). The following general suggestions can help establish consistency in group work:
•During a pre-collaboration period, make sure that students are motivated to participate.
•Establish clear ground rules: everybody must participate, and all the ideas should be accommodate.
•Be available as a resource for students, but do not offer any judgments on the work progress and assure them that the tensions are natural.
•Do not get discouraged when a collaborative task results in some emotional responses from students – keep creating opportunities for learning to work collaboratively.
