Developing and Implementing Prediction-Observation-Explanation Worksheets of Healthy Foods

Muammer Çalık, Zeynep Bayçelebi.




Abstract

The aim of this study was to develop prediction-observation-explanation (POE) worksheets of healthy foods and to investigate their effects on grade 3 students’ conceptions. The sample of the study consisted of 10 grade 3 students at a primary school in the city of Bayburt. Within a pre-experimental research design, data were collected throughout a word association test (WAT), a conceptual understanding test (CUT) and POE worksheets. The results showed that even though the number of the response words in post-WAT (f=256) was higher than in pre-WAT (f=212), there was no statistically significant difference between the students’ scores of pre- and post-WAT. However, a large Hedge’s g value and statistically positive change in scores of pre- and post-CUT pointed that the POE worksheets resulted in better conceptual understanding.In brief, the POE worksheets were effective at improving the students’ conceptions and awareness of healthy foods. In light of the results, the current study suggests using the POE worksheets for science teaching in primary schools.

Key words: Grade 3 Students, Healthy Foods, Prediction-Observation-Explanation Strategy, Science Education, Worksheet.
