<P> Social constructivism has been studied by many educational psychologists, who are concerned with its implications for teaching and learning . Social constructivism extends constructivism by incorporating the role of other actors and culture in development . In this sense it can also be contrasted with social learning theory by stressing interaction over observation . For more on the psychological dimensions of social constructivism, see the work of A. Sullivan Palincsar . Psychological tools are one of the key concepts in Vygotsky's sociocultural perspective . </P> <P> An instructional strategy grounded in social constructivism that is an area of active research is computer - supported collaborative learning (CSCL). This strategy gives students opportunities to practice 21st - century skills in communication, knowledge sharing, critical thinking and use of relevant technologies found in the workplace . </P> <P> Additionally, studies on increasing the use of student discussion in the classroom both support and are grounded in theories of social constructivism . There is a full range of advantages that results from the implementation of discussion in the classroom . Participating in group discussion allows students to generalize and transfer their knowledge of classroom learning and builds a strong foundation for communicating ideas orally . Many studies argue that discussion plays a vital role in increasing student ability to test their ideas, synthesize the ideas of others, and build deeper understanding of what they are learning . Large and small group discussion also affords students opportunities to exercise self - regulation, self - determination, and a desire to persevere with tasks . Additionally, discussion increases student motivation, collaborative skills, and the ability to problem solve . Increasing students' opportunity to talk with one another and discuss their ideas increases their ability to support their thinking, develop reasoning skills, and to argue their opinions persuasively and respectfully . Furthermore, the feeling of community and collaboration in classrooms increases through offering more chances for students to talk together . </P> <P> Given the advantages that result from discussion, it is surprising that it is not used more often . Studies have found that students are not regularly accustomed to participating in academic discourse . Martin Nystrand argues that teachers rarely choose classroom discussion as an instructional format . The results of Nystrand's (1996) three - year study focusing on 2400 students in 60 different classrooms indicate that the typical classroom teacher spends under three minutes an hour allowing students to talk about ideas with one another and the teacher . Even within those three minutes of discussion, most talk is not true discussion because it depends upon teacher - directed questions with predetermined answers . Multiple observations indicate that students in low socioeconomic schools and lower track classrooms are allowed even fewer opportunities for discussion . Teachers who teach as if they value what their students think create learners . Discussion and interactive discourse promote learning because they afford students the opportunity to use language as a demonstration of their independent thoughts . Discussion elicits sustained responses from students that encourage meaning - making through negotiating with the ideas of others . This type of learning "promotes retention and in - depth processing associated with the cognitive manipulation of information". </P>
