formation of collaborative groups in a the self of the three steps method The aim of this paper is to present problem-based learning environment. The self-formation of collaborative groups is based on sharing of accountability among students for solving instructional problems. The steps of the method are planning collaborative problem solving, self-evaluation of students, and building collabora...

The importance of empirical studies in software engineering cannot be under-stated. Care must be taken, however, that the experimental methods employed are appropriate and that they are executed with due scientiic rigour. A critical commentary is presented of a paper by Sinha and Vessey 6] which attempted empirical evaluations of a number of propositions concerned with the notion of cognitive t...

This study tested a model of teacher interventions (TIs) conducted during cooperative learning to examine how they affected students’ subsequent time on-task (TOT) and problem solving. TIs involved groups of ninth-grade students working on an algebra problem; videotaped lessons were transcribed and analyzed. Results showed that teachers initiated most TIs and typically did so when students were...

The Assessment and Teaching of 21 Century Skills (ATC21S) project had a research and development plan that reflected a traditional approach to conceptualisation of constructs, and then establishment of test blueprints followed by test construction. The test construction process included several stages – of drafting task ideas, panelling these with teachers, then piloting revised tasks, and tria...

Oftentimes, learning mathematics involves using technology as a conscious attempt to understand the material in a new and accessible mode, to increase performance, and to expand one’s knowledge regardless of the level of training. While comparative assessments of students’ performances in blended and face-to-face environments are essential, the authors of this paper analyze students’ mathematic...

People who attempt to use a complex infonnation store on a computer encounter a number of problems: They do not know what information exists or how to find infonnation, they get no support in articulating a question, and they are unable to phrase their question in terms that the system understands. HELGON, an intelligent environment that supports limited cooperative problem solving, helps peopl...

Knowledge has been widely recognized as a critical resource for competition. Then it seems important to analyze organizational performance based on a cognitive approach. In this paper, this approach consists in the identification of two main classes of organizational problem (repetitive and innovative) and two main cognitive processes (codification and interpretation) involved in problem solvin...

During goal-directed menu search the user assesses the relevance of an item to their goal and then has a choice between selecting the current item or continuing to assess the remaining items in the choice set. An obvious influence on selection is the relevance of the goal label to the task description (Franzke, 1995). Interestingly, Young (1998) has proposed that there is interdependency betwee...

Anisocoria during anesthesia is very rare, but may indicate life-threatening neurologic injuries and create tremendous condition. A 23-year-old male patient was anesthetized with fentanyl and propofol. Thirty minutes after inducing anesthesia, unilateral mydriasis was detected. The duration of surgery was shortened for prompt evaluation of the pupils. At the end of the operation neither vision ...

Engineering as a profession faces the challenge of making the use of technology ubiquitous and transparent in society while at the same time raising young learners’ interest and understanding of how technology works. Educational efforts in science, technology, engineering, and mathematics (i.e., STEM disciplines) continue to grow in pre-kindergarten through 12th grade (P-12) as part of addressi...
