Abstract

The purpose of this study is to investigate 1) the types of knowledge students ask for in their reading comprehension of science textbooks using an online annotation system, 2) the accuracy of the knowledge provided by the students to their peers, 3) the frequency of knowledge sharing behaviors, 4) the evaluation of the effect of collaborative reading, and 5) the trust among peers as knowledge sharers. Questions made by 241 students in the second grade of middle school using an online annotation system in two chapters of the science textbook were analyzed using Bloom's revised taxonomy and their answers were grouped according to five accuracy categories. Also, questionnaires for the evaluation of the effectiveness of collaborative reading comprehension and of trust among the students were used. The students asked their peers 'understanding questions' which comprised almost 80% of the total questions they made and were similar with individual metacognitive strategies for reading comprehension. Of the total threads, 71% has scientifically correct threads shared by the students. The frequency of the knowledge sharing behaviors was high but this was affected by the rewards (point system). Students evaluated that collaborative reading comprehension conducted through an online annotation system were helpful in their learning. In addition, the ratio of students trusting their peers who did the knowledge sharing is over 80%. This study shows that when students use an online annotation system, they can fill one another's cognitive gaps in the reading process by sharing knowledge. Also, collaborative reading using an online annotation system has proved that cognitive individualization is possible through sharing knowledge interactively and dynamically, unlike reading hard copies of textbooks which are a one way information transfer.

이 연구에서는 온라인 주석시스템을 이용한 과학교과서 독해 과정에서 학생들이 동료들에게 요청한 지식의 종류, 학생들이 동료들에게 제공한 지식의 정확성, 지식공유행동의 빈도, 협력적 독해의 효과성에 대한 학생들의 평가, 그리고 동료 간 신뢰의 정도를 조사하였다. 중학교 2학년 241명의 학생이 과학 교과서의 2개 대단원을 온라인 주석시스템을 이용하여 작성한 주석(질문과 답변)을 Bloom의 개정된 분류틀과 답변의 정확성 분석틀을 이용하여 분석하였다. 또 효과성 설문지, 인지기반 신뢰와 정서기반 신뢰 측정 도구를 사용하였다. 학생들이 교과서를 읽으면서 만든 질문의 80%는 '이해 질문'이었고, 이 유형의 질문은 개인의 독해를 위한 메타인지 전략과 유사하였다. 이러한 요구에 의해 학생들 간에 공유한 지식은 71%가 과학적으로 올바른 지식이었다. 지식공유행동의 빈도를 살펴보면 학생들은 온라인 주석시스템을 이용한 독해과정에서 활발하게 지식공유행동을 수행하였으나, 행동의 빈도는 보상에 크게 영향을 받는 것으로 보인다. 학생들은 온라인 주석시스템을 통해 수행한 지식공유행위가 학습에 도움이 되었다고 평가하였다. 또한 학생들끼리 서로를 지식공유자로서 신뢰하는 비율은 80% 이상으로 나타났다. 이 연구를 통해 온라인 주석 시스템을 사용하여 독해를 하였을 때 학생들이 지식공유를 함으로써 독해과정에서 발생한 어려움을 극복할 수 있었음을 알 수 있다. 또한 온라인 주석 시스템을 사용한 협력적 독해는 일방향적인 정보전달에 그쳤던 기존의 교과서 읽기와 달리, 쌍방향적이고 역동적으로 지식을 공유하게 함으로써 인지적 개별화 교육이 가능하도록 함을 확인하였다.
