The Crucial Role of Semantic Fields in the Development of Problem Solving Skills in the School Envixtualized” problem solving processes and the “non-contextualized” problem solving processes? Which teaching actions associated with the chosen contexts can the teacher perform in order to enhance pupils‘ results in problem solving?

Pre-Algebraic Problem Solving,thinking allows pupils to do concrete experiments and get feedbacks from the problematic-situation; and this, in the long run, is useful in order to jump to relational polarity, where more formal algebraic manipulations can be done.

Problem Solving in Geometry: From Microworlds to Intelligent Computer Environments,nment may affect the solving processes and the kind of solution elaborated by the student. After presenting the general principles underlying what an intelligent help provided by a computer environment can be, an example is proposed in the case of a specific geometrical task for which a prototype “Hypercarré” has been designed.

事與愿違

Aspects of Computerized Learning Environments Which Support Problem Solving,e following software features were identified as particularly relevant: tool character, non- evaluative feedback, and operational structure; this structure should include a limited number of operations, predominantly transformations modelling the underlying mathematical domain.

Inspired by this hypothesis, many investigators have jointed to the field of antiangiogenesis with an obvious goal of finding angiogenesis inhibitors that block tumor growth and metastasis. Over the last decade, the field of antiangiogen

Neuropsychological work-up should also cover an emotional state, psychosocial adjustment and competence in everyday life of the patients.
