Abstract:

The Didactic Guide is a valuable tool complementing and making learning more dynamic. It is done using creative didactic strategies that simulate the presence of the tutor and generate a dialogue in order to offer students different possibilities to improve their understanding and self-discovery learning.This way the student is the protagonist of his own learning process. In this context, is highly important to consider the self discovery learning as a goal facilitating significant learning. The use of practical guides enables students to manage their own time, goals, techniques, contents and evaluation. In medical histology teaching several models of didactic guides could be use, and they normally include numerous activities, text, questionnaires, pictures, and drawings that may enhance the effectiveness of this tool in the learning process. In this work we have evaluated the usefulnes of different sections of a histology didactic guide in order to determine the key sections that enhance the learning process in human histology.

For this purpose, a practical histology guide was designed with different sections: message text, theoretical text, objectives, drawings, pictures, clinical cases, games, blank spaces for self notes and drawing and final self evaluation questions. First, a simple questionnaire was applied in 90 students enrolled in histology practical seccions to analyze the student´s perceptions and preferences related to the histology guide. Finally, for all questionnaires average results and standard deviations were calculated for each option and all participants, as well for each gender, separately. Comparisons were done for drawings vs drawing blank spaces, teoric content vs notes blank space, drawings vs pictures and for each gender separately using Mann-Whitney non-parametrical test.

Our findings revealed that visual strategies such as images and pictures were considered to be more useful for learning histology in the practical session. Similary, the students rated the self evaluation questions and blank spaces for self notes and drawing to be more attractive to the students. However, texts with theoretical information, messages, objectives, and clinical cases revealed to be less useful for the students in the learning process of medical histology. Moreover, statistically significant differences between theoretical content vs notes blank space was observed. All these results point out the importance of including pictures and drawings in the practical guide accompained of blank spaces that allow the development of creativity and autonomy that lead the students into a self discovery learning. Interestingly the students do not appreciate the presence of theoretical background in the practical guide as relevant information for their academic formation in the practical session.
