Item A Three-Tier Diagnostic Test to Assess Pre-Service Teachers’ Misconceptions about Global Warming, Greenhouse Effect, Ozone Layer Depletion, and Acid Rain(International Journal of Science Education, 2012-06-11) ARSLAN, Harika Özge; ÇİĞDEMOĞLU, Ceyhan; MOSELEY, ChristineThis study describes the development and validation of a three-tier multiple-choice diagnostic test, the atmosphere-related environmental problems diagnostic test (AREPDiT), to reveal common misconceptions of global warming (GW), greenhouse effect (GE), ozone layer depletion (OLD), and acid rain (AR). The development of a two-tier diagnostic test procedure as described by Treagust constitutes the framework for this study. To differentiate a lack of knowledge from a misconception, a certainty response index is added as a third tier to each item. Based on propositional knowledge statements, related literature, and the identified misconceptions gathered initially from 157 pre-service teachers, the AREPDiT was constructed and administered to 256 pre-service teachers. The Cronbach alpha reliability coefficient of the pre-service teachers’ scores was estimated to be 0.74. Content and face validations were established by senior experts. A moderate positive correlation between the participants’ both-tiers scores and their certainty scores indicated evidence for construct validity. Therefore, the AREPDiT is a reliable and valid instrument not only to identify pre-service teachers’ misconceptions about GW, GE, OLD, and AR but also to differentiate these misconceptions from lack of knowledge. The results also reveal that a majority of the respondents demonstrated limited understandings about atmosphere related environmental problems and held six common misconceptions. Future studies could test the AREPDiT as a tool for assessing the misconceptions held by pre-service teachers from different programs as well as in-service teachers and high school students.Item Taking attention on environmental issues by an attractive educational game: enviropoly(Procedia - Social and Behavioral Sciences, 2011-08-08) ARSLAN, Harika Özge; MOSELEY, Christine; ÇİĞDEMOĞLU, CeyhanResearches in interdisciplinary teaching methodologies on environmental education and in assessing their impact were recommended in Thessaloniki Declaration (UNESCO, 1997). Therefore, the purpose of this qualitative study was to develop and field test an educational game, EnviroPoly, to promote environmental literacy. The game was piloted with 44 elementary/mid level pre-service teachers. Afterwards five pre-service teachers met in a focus group to discuss the game and its procedures. The discussions and observations of the large group of teachers during play and the smaller focus group indicated that EnviroPoly is attractive, motivating, enjoyable and useful. Additionally the game was found to be applicable for different grade levels by adapting reading and question cards.
