Also, the organization of Science classes for the dyslexic student is briefly discussed. Then information regarding concept maps is given. A presentation and quick discussion of four evaluation sheets with concept maps in the science subjects of Chemistry, Biology and Physics is performed. The main part of this paper presents the questionnaire along with a discussion regarding its results. Finally, conclusion are drawn and future work is mentioned.
