Teaching learning disabled adolescents to think critically using a problem‐solving schema

Abstract

In this study we describe and examine the effectiveness of an instructional program designed to teach learning disabled adolescents to make better personal decisions. We presented problems in short narratives based on the types of problems these students must solve in their own lives. The program, conducted as part of the students' regular resource room curriculum, incorporated schema‐general questions for problem solving coupled with practice in generating problem‐specific questions to reach an appropriate decision. Participants were 70 resource room students in two large, urban high schools. We employed a pretest‐posttest comparison group design. On the posttest, instructed students performed significantly better on (1) identifying a general schema for making a personal decision and (2) applying the schema to reach appropriate decisions concerning novel problem narratives. The results support the view that application of a general schema to specific problems can be an effective instructional method to improve critical thinking and decision making.     

Realization of Techniques in Problem Solving: The Construction of Bijections for Enumeration Tasks

This paper deals with a teaching approach aimed to help students become aware of targeted techniques of significance in problem solving. The teaching approach is to present a series of tasks that all can be solved by applying the same technique. Two levels of prompting are used; first for the students to realize solutions without necessarily being cognizant of the technique, second for them to perform further mathematical modeling that should highlight the similarities in solution shared by all the tasks. In the fieldwork, a teaching sequence based on this approach is implemented for a technique involving enumeration via constructing a bijection. Certain factors in the students' behavior suggested that their realization of the technique at the end was not as secure as desired. Some modifications of the teaching sequence are proposed to counter these factors.     

Software engineers helping themselves: The web resource collaboration center

Conclusion By implementing knowledge management features in an EPSS-like structure, the WRCC provided a more effective performance solution that was in alignment with the firm’s business objectives, making sure that both the employees’ learning and performance needs and the firm’s needs were addressed (Stone & Villachica, 2003). The activity of building a WRCC helped the software engineers learn about new tools and languages in the software engineering domain, while constructing a knowledge base to support their future learning and professional development in that domain. In addition, their work on the WRCC helped software engineers strengthen their connections to the larger software engineering communities of practice while they developed a local learning community that encouraged sharing, coaching and mentoring. Ultimately, the firm was able to reduce their reliance on conventional training by 70% - their original goal — by allowing the software engineers to create and use an on-the-job learning architecture that was more situated, social, transparent, open, flexible and respectful of their workplace learning and professional development needs.
