Aim of Intervention:  To evaluate knowledge on the use of antibiotics in students and to evaluate the efficacy of the school intervention in improving students’ knowledge on correct antibiotic use.

Target Population: 82, 9^th grade students.

Target Place: 2 Middle Schools in Braga, Portugal.

Time Period:  2013 (over 2 months)

Intervention Tool(s): pre-test à teaching activity (slideshow) and class discussion à 2 months later, post-test.

Technology: Slide presentation (computerized slide show), data analysis using SPSS software for Windows, version 18.0 (SPSS Inc., Chicago, IL, USA).

                                       

Results: The results in the post-test for both schools improved significantly students’ knowledge in respect to the obligation to comply with the schedule set, with 73% and 82.2% of correct answers respectively and, regarding the development of resistant bacteria with 62.2% and 84.4% of correct answers. 

Costs: Printing fees for tests, fees for registered statistical software.

Personal Reflection: Quick, feasible, low-cost, and focused. The two - month gap in between teaching activity and post-test “forced” students to retain and make explanations more concrete and specific, thereby testing and promoting long-term memory learning. Limitations of this study included the failure to assess each child’s improvement individually as the cumulative class average for both the pre-test and post-test were evaluated instead.
