The article presents results of the evaluation of the GLOBE program (Global Learning and Observations to Benefit the Environment) in the Czech Republic. The evaluation explores the implementation of the program in schools and its impact on research skills. Four hundred and sixty six pupils, aged 13, from 28 different schools participated in the evaluation. The evaluation revealed problems with the implementation of the program in schools. The majority of pupils usually collect data and work with worksheets in the program. The other activities, such as the analysis and comparison of collected data or planning GLOBE activities, are done only occasionally or never. Although one of the main goals of the program is to develop pupils' research skills, the program had no measurable effect on this outcome. According to these results, changes in the way the program is implemented are needed. Recommendations for further program development and evaluation are discussed.
