자기주도학습을 암묵적으로 다루는 과학내용수업과 명시적으로 다루는 자율학습자수업으로 구성되어 있는 과학영재 프로그램에 참여한 중학생들에게 매 수업마다 평가의 일부로 수업에서 만족스러운 점을 서술하도록 하였다. 본 연구에서는 이 두 가지 수업에 대한 학생들의 평가에서 언급되는 자기주도학습 관련 요소들을 비교하였다. 첫째, 자기주도 학습 관련 하위요소의 대부분이 학생들의 평가에 언급되어 있었다. 수업 평가에서 만족스러운 이유를 조금이라도 구체적으로 서술한 경우, 거의 언제나 자기주도학습 관련 요소들을 포함하고 있었으며 분류기준에 있는 대부분의 하위요소가 언급되었다. 그러므로 대부분의 학생들이 자기주도학습 관련 요소들을 인식했고, 그에 대해서 만족스러워했음을 알 수 있다. 둘째, 두 가지 수업에 대한 평가에서 자주 언급되는 자기주도학습 관련 요소와 빈도에 차이가 있었는데, 자율학습자수업에 대한 평가에서 더 많은 요소들이 더 높은 비율로 언급되었다. 예를 들어 탐구기반 차원의 하위요소인 조별활동은 두 수업에서 동일하게 수행되지만, 자율학습자수업에 대한 평가에서 더 자주 언급되었다. 자율학습자수업 평가에서 더 자주 언급된 하위요소들로 인지차원에서 조직화, 계획, 점검, 동기차원에서 자아효능감과 성취가치, 행동차원에서 행동 통제 등이 있다. 한편 일반인지 차원의 하위요소인 지식의 정교화는 주로 과학내용수업 평가에서 언급되었으며, 동기차원의 하위요소인 목적지향은 두 수업에서 모두 많은 학생들이 언급하였으나 과학내용수업 평가에서 더 많은 학생들이 언급하였다. 따라서 두 가지 수업에서 학생들이 인식하는 자기주도학습 관련 요소들에 차이가 있으며 두 수업이 서로 보완적이며 두 가지 수업이 모두 필요한 것으로 보인다.

The purpose of this paper is to compare the two different instruction methods for Korean learners of academic purposes in learning request expression. Participants were divided into two groups, explicit and implicit group. Both groups viewed several scenes from the drama that involved native speakers interacting in different situations. The instructional treatment for the explicit group included metapragmatic information while the treatment for the implicit group did not. On the other hand, the treatment for the implicit group followed implicit techniques, which were repetition of the video presentation and a script reading activity. This study was made up of a pre-test, a post-test, and a delayed-test. The pre-test was conducted prior to the instructional treatment. The post-test was administered a day after the last instruction and the delayed-test was conducted five weeks after the treatments. Two types of tests, speaking and writing, were used in this study to examine subjects' knowledge of Korean request. The result of this research reveals that implicit treatment was more effective than explicit treatment in Korean learners' request acquisition. This results might have been due to the operationalization of the implicit condition in this study. Implicit instruction may help language learners make rules by themselves through tasks.

The purpose of this study was to explore the effect of an explicit word instruction for EFL beginning readers and their perception on the learning experience. Data were attained from 16 fourth graders who took English class as a development activity. Data include the results of pre- and post-test of high frequency sight word recognition, oral reading ability, students' survey responses, and teacher observation. The descriptive statistics were obtained for the result of the pre- and post-test. The findings from the student survey and teacher observation were also provided and interpreted to better understand the result of project and students' perception on the learning experience. The followings are the results of this study. The word recognition ability of the students was dramatically improved after the project. The students were satisfied with the overall learning experience perceiving it as helpful and fun learning. They expressed that the explicit word instruction helped their word recognition and reading ability. The results also supported that the confidence of students on their reading ability were heightened. Several suggestions are made for teachers and researchers on the word instruction for young EFL learners who are beginning readers.

본 연구는 주의편향수정(Attention Bias Modification; ABM) 훈련에서 지시문(명시형, 암묵형)과 자극제시 시간(300 ms, 500 ms)에 따른 ABM 훈련의 효과를 대학생 사회불안 증상 집단을 대상으로 확인하고자 하였다. 부산 소재 대학의 대학생을 대상으로 사회적 회피 및 불편감 척도(Social Avoidance and Distress Scale; SADS)가 82점 이상이면서 주의편향 점수(Attention Bias Score; ABS)가 0보다 큰 참가자를 ABM 훈련 대상자로 선정하였다. 훈련 집단은 명시형-300 ms 집단(n=10), 명시형-500 ms 집단(n=8), 암묵형-300 ms 집단(n=8), 암묵형-500 ms 집단(n=7)이었다. 암묵형 지시문 집단에는 ABM 훈련 실시 절차 정보만을 제공하였다. 명시형 지시문 집단에는 추가로 훈련 조작(탐침이 항상 중성 자극이 나타났던 위치에 나타남)에 대한 정보를 제공하였다. 그리고 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 통제 집단은 통제-300 ms 집단(n=5), 통제-500 ms 집단(n=7)으로 구성하여 중성-중성 자극 쌍만을 제시하였다. 역시나 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 총 8회기의 ABM 훈련을 완료하고 SADS와 ABS를 재측정하였다. 분석 결과, ABM 훈련 효과는 지시문 집단에서만 나타났다. ABS 감소는 세 집단(명시형 지시문, 암묵형 지시문, 통제)에서 모두 유의하였지만, 명시형 지시문 집단의 처치 효과가 가장 효과적이었다. SADS 점수 감소는 명시형 지시문 집단에서만 유의하였다. 자극제시 시간에 따른 ABM 훈련 효과의 차이는 나타나지 않았다. 본 연구 결과는 명시형 지시문이 암묵형 지시문에 비해 ABM 훈련 효과를 증진시킬 가능성이 있음을 시사한다.

In this study, we investigated the effects of explicit instruction about nature of science by elementary school students' cognitive level. Participants were six classes, 187 sixth graders at elementary schools in Daegu. Three classes were assigned to control groups and the other classes to treatment groups. Control groups were provided normal instructions and treatment groups were provided instructions integrated with nature of science about chapter 'electromagnet' for 9 class periods. The results of this study were as follow. Both low-cognitive level students and high-cognitive level students in the treatment groups are improved in understanding about nature of science by the explicit instructions about nature of science. Especially, the high-cognitive level students had more improvement than the low-cognitive level students in understanding about nature of science by the explicit instructions about nature of science. There were no significant differences between the test scores of the two groups in the science interest sub-domain of the science-related affective domain. But, there were significant differences between the test scores of the two groups in curiosity and open-mindedness of the scientific attitudes sub-domain of the science-related affective domain.

This study investigates the effects of three different types of instruction, namely form-based, comprehension-based, and production-based on the development of Korean university students' (n=137) comprehension and production of English relative clauses (RCs). The extent of improvements was analyzed by administering pre-and post-tests consisting of two comprehension tests (selecting the right form of RCs and the right picture descriptions) and one production test (combining two sentences). Findings of this study suggest that all three types of instruction increased participants' comprehension and productions of RCs. However, there appeared differential effects by the instruction type. It was found production-based instruction was most effective in promoting comprehension, followed by comprehension-based instruction. Comprehension-based instruction worked best with the development of production, suggesting that the effects of comprehension training did not only work for increasing comprehension skills, but also transfer to production skills. The type or level of tasks employed for each instruction appeared to play an important role in causing such results. Form-based instruction displayed the lowest improvements in both comprehension and production of RCs. A sentence-combination task employed for form-based instruction appear to result in mere explicit rule explanations without chances to notice rules in context or use their knowledge in practice.

The purpose of the study is to investigate whether focus-on-form instruction is effective in promoting accuracy in writing and to make some suggestions regarding education in business English writing. For this purpose, an experiment, of which the participants were 29 college sophomores taking a course in business English, was made. The learners received instruction in the English nouns followed by modificatory phrases or clauses through the focus-on-form techniques, feedback and explicit explanation. The results were as follows: First, the learners who received focus-on-form instruction improved accuracy in writing. Second, there was a correlation between the learners' English proficiency levels and the effects of focus-on-form instruction. Third, the high level learners showed more positive attitude toward focus-on-form instruction than the low level ones. To promote accuracy in written business communication, the following suggestions were made on the basis of the results: First, focus-on-form instruction should be incorporated into a content-based business English class. Second, repeated focus-on-form instruction is needed. Third, learners' English proficiency levels should be taken into account when focus-on-form instruction is given.

One of the learning difficulties for Korean learners of English is the intonation of English focused yes/no questions. Focused words in English yes/no questions are realized as low pitch accents which contrast with high pitch accents in Korean counterparts. In order to improve Korean students' intonation, direct and metalinguistic explanations on the intonation of English focused yes/no questions were given to Korean learners of English. In pre-tests and post-tests, students' perceptions on the target items were measured. The study results showed that phonetic explanation using intonation contour enhanced students' perception on English intonation. With respect to the position of focused words, sentence initial and medial focused questions were more difficult than sentence final focused questions. The perception was most improved in sentence initial focused questions. The study showed the immediate effects of the explicit instruction on perceptions of English intonation.

This study aims to analyze the effects of explicit lexical collocation instruction on grammatical collocation knowledge, by focusing on the preposition collocations. The forty participants consisting of twenty men and twenty women are currently freshmen English majors in college. They responded to the questionnaire on their basic lexical learning strategies in pre-post tests, and carried out a lexical collocation test and a preposition collocation test as pre-post tests. They took the open class on the lexical collocations(LC) 5 times, but they did not concretely study any grammatical collocations(GC). Each test is analyzed and compared with pre-post tests by SPSS 12.0. From all the analyses, it was first revealed that most students who didn't know about the concepts, types and uses of collocations became aware of them after the class. The effects of the lexical collocations on the lexical collocation knowledge were quite revealing. Second, the correlations between the lexical collocations and grammatical collocations were not significant, although relations among the lexical collocations were quite significant. Finally, some suggestions for methods of mixed lexical chunks instruction are made for students' productive skills. Also, it is suggested that more profound attention should be paid to giving direct instructions on the basis of the lexico-grammatical continuum between LC and GC.
