This study analyzed the cognitive domain focused on the topic of ‘World of Plants’ by brain-based evolutionary approach (ABC-DEF). A comparison group consisting of 20 4th students received a traditional textbook-based instruction and an experimental group of 20 4th graders received a brain-based evolutionary approach focused on cognitive domain (C-DEF). For the study, through the pre-post scientific knowledge test, C-DEF activity sheet, and interview with the students both quantitative and qualitative data were collected. The major results of the study are as follows. First, the number of scientific concepts of comparison group was 27 of the total 40 concepts (67.5%) and that of experimental group was 26 of the total of 31 concepts (83.9%). The number of scientific concepts presented in two groups was similar, but the proportion of misconceptions was lower in experimental group. The comparison group showed no statistically significant difference between pre-post tests, whereas the experimental group showed significantly higher score of scientific concepts in post than pre test. Second, whithin the C-DEF activities of the experimental group, 70% of students presented more than four kinds of meanings on activity results at the C-D stage. At the C-E stage, 42.1% students answered “It’s new and interesting” and 57.8% students answered “it is useful in life”. At the C-F stage, the students considered the criteria of originality and usefulness when they apply what was known and the contents showed a tendency of ‘Why’ type of biological knowledge.

인지적 영역 중심의 뇌기반 진화적 접근법을 적용한 초등 과학 수업에서 학생들의 과학 창의성 분석

A brain-based evolutionary approach developed by reflecting the brain functions and authentic science is consisted of Affective, Behavioral, and Cognitive domains, and within each domain the processes of Diversifying, Evaluating, and Furthering are proceeded (ABC-DEF). Two core components of creativity of originality and usefulness are inherent in each step. So, this study analyzed scientific creativity with the originality and usefulness components in cognitive domain, which is composed of diversifying the meanings inherent in the results of observations or experiments (C-D), evaluating the meanings (C-E), and furthering (C-F) in learning of `World of Plants` unit which includes two topics of `Plants on Land` and `Plants in Water and Special Environment`. A total of 20 fourth grade students at Y elementary school in Gyeonggi province participated in the study. The main results of this study are as follows. First, the scientific creativity in step C-D (Diversifying stage) was assessed according to the scientific creativity assessment formula. The scores of scientific creativity were quite different with topics and showed different pattern in the originality and usefulness components. Second, when the students compare and evaluate the values of each meaning (C-E stage), they weighed more on usefulness than originality, such as “because it is useful” or “because it solve many everyday problems”. Third, the overall scores of scientific creativity in step C-F (Furthering stage), as compared with those of step C-D, were low and showed decrease in the average scores of originality from 9.8 to 7.5 points, whereas increase in the average scores of usefulness from 5.4 to 6.1 points. In conclusion, these results showed that, even though the levels were not so high, the students, as scientists, can exhibit the scientific creativity in the processes of diversifying, comparing and evaluating, and applying the meanings about the results obtained by observations or experiments. The specific and various strategies to help students express their potential scientific creativity more effectively need to be developed.
