The aim of this study is to determine the effect of STEM-based
environmental education in which microcontroller sets are integrated on
pre-service teachers' environmental literacy. The study was carried out
with a one-group pretest-posttest weak experimental design. The sample
of the study consisted of 31 pre-service teachers attending biology,
science, and chemistry education departments. As the data collection
tool, the environmental literacy scale including knowledge, attitude,
behaviour and awareness dimensions was applied to the sample group as
a pre-test and post-test. The study lasted for 11 weeks in total, including
training on microcontroller sets, STEM-based environmental education
and application of tests. During the environmental education, the
participants were divided into groups of 4-5 and the studies were carried
out with the station technique. In the stations, a research problem about
air, water, soil, light and noise pollution was posed to the participants.
They were expected to propose a solution using microcontroller sets. At
the end of the research, a statistically significant difference was
determined between the pre-test and post-test scores of the pre-service
teachers from the environmental literacy scale. Accordingly, it was
concluded that STEM-based environmental education improved preservice teachers' environmental literacy. Based on these results, it is
recommended that experimental/ quasi-experimental studies
investigating the effectiveness of STEM-based environmental education
and studies determining the advantages and disadvantages of STEM
based environmental education using microcontroller sets should be
carried out.
