STS 자료를 활용한 ARCS 수업전략이 중학생의 학업성취도 및 과학에 대한 학습태도에 미치는 영향 -생식과 발생 단원을 중심으로- = The Effect of ARCS Strategy using STS Materials on Students` Learning Achievement and Learning Attitudes toward Science in the Middle School Science Classes -Focused on the Unit of Reproduction and Development-

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of Keller`s ARCS strategy using STS materials on the middle school students` learning achievement in the unit of reproduction and development, learning attitude toward science, and the perception on STS. The experimental group was taught by the ARCS strategy using STS materials, while the control group was taught by the traditional teaching method. The results indicated that the experimental group and control group students represented the similar scores on learning achievement in the post-test 1 right after the treatment (p>.05). In the post-test 2 after 4 months, however, the experimental group represented the higher scores than the control group did (p<.01), indicating that the experimental group students retained their knowledge. In addition, the experimental group students represented the higher scores in learning attitude toward science as well as STS perception than the control group students did (p<.05). Overall, ARCS strategy using STS materials helped retain students` knowledge, and improved learning attitude toward science, as well as perception on STS.
