Abstract

The aim of this paper about teaching was evaluate the impacto of the teaching by investigation with play ful resources, Word search puzzle and Cards, about learning in Microbiology themes in High School (EM) and use the results in a composition of a book let about investigative activities. Research conducted in two State Schools (1) and (2) in the city of Timon-MA. Descriptive exploratory longitudinal study with quanti/qualitative approach occurred between October and December, 2018.

Returned to the questionnaire about fungi in the first activity nad about bacteria in these cond, plus Five items that the students evaluated the used methodology as bad, regular, good, great or excellent. The impact of the methodology evaluation about the learning was based in HAKE (2002): g = (%) post − (%) pre / 100(%)−(%) pre, where g is thes tandardized gain; (%) post is the score o faccuracy post-test apllied af terthe implementation of the methodology; (%) pre is the score ofaccuracy post-test apllied before the intervention, and 100% is the maximum percentage of possible hits. Analytical Instruments: Excel Spread sheet version 10; Statistical Package for the Social Science Software (SPSS version 22) and Chi Square Test; KS Normality Test;T-Test, in the case of parametric samples or Wilcoxon Test. The confidencelev elwas 95%. The results indicatet hat 77,0% of the texts about fungi and 92,3% about bactéria belongs to the categories C, with 8 to 9 cited characteristics, D, with 10 to 11 or E, with 12 or more, respectively. In the students evaluation the methodology received good, great or excellent concepts. The impact of the methodology about the learning was 62,3(medium) with search puzzle Word and 67,0(medium) with Cards.
