This study investigated the effects of dictation practice, in terms of listening proficiency and the use of listening strategy. The research was implemented for 15 weeks with 89 freshmen and sophomores at a Korean university. The subjects were divided into an experimental group and a control group. All conditions were the same in both groups, except that the experimental group had dictation practice on a regular basis in their listening classes through one semester. For the purpose of the study, two research questions were set; 1) Does dictation practice improve listening proficiency? 2) What are the differences in the use of listening strategies between the two groups? Does dictation practice make the participants use different listening strategies? A sample TOEIC listening test was conducted as a pre-test and post-test. A questionnaire was used to find out the differences in the use of listening strategies between the two groups. The results of this study reveal that there was no statistically difference in improvement between the two groups; however, the experimental group scored much higher on the post-test than the pre-test compared with the control group. In regard to listening strategies, among 6 listening strategies, the use of metacognitive listening strategies had a significant difference between the two groups. On the basis of the results, the study suggested some guidelines for dictation practice in EFL listening classes and called for more studies on its effects.

이 연구의 목적은 CASE 활동 중 변인통제 문제해결 활동에서 나타나는 학생들의 인지수준에 따른 학생-학생, 교사-학생 사이의 상호작용을 분석하고, 이를 바탕으로 학습자의 인지수준에 따라 교수학습과정에서의 상호작용을 바람직한 방향으로 촉진할 수 있는 방법을 모색하는 데 있다. 변인통제 문제해결 활동에서 상호작용이 어떻게 일어나는가를 분석하기 위하여 학생들의 활동을 관찰, 녹음하였고 이를 전사하여 분석하였으며, 학생들을 대상으로 면담을 실시하였다. 토론의 모든 과정을 주도하는 것은 주로 조 내에서 상대적으로 인지수준이 높은 학생들이었다. 인지수준이 높은 학생이 토론을 주도하지 못하는 조의 경우는 문제인식과 해결이 원활하게 이루어지지 않았다. 또한 학생들은 문제를 인식할 때 문제가 제시되는 상황에 크게 의존하였다. 인지수준이 낮은 학생들은 인지수준이 높은 학생에 비하여 문제를 인식하고 해결하는데 어려움을 겪었다. 인지수준이 낮은 학생들은 특히 문제상황에서 변인을 잘 찾아내지 못하였고, 원인변인과 결과변인을 잘 구분하지 못하였으며, 동시에 고려할 수 있는 변인의 수가 적어 변인통제를 잘 하지 못하였다. 이들은 또한 자신보다 능력이 뛰어난 동료나 교사와의 상호작용을 통하여 문제를 인식하고 해결하였고, 반면에 인지수준이 높은 학생들은 스스로 또는 자신과 마찬가지로 인지수준이 높은 학생과의 상호작용을 통하여 문제를 인식하고 해결하였다. 조 안에 인지수준이 높은 학생이 토론을 주도하고 있을 경우에는 조원들 사이의 상호작용만으로도 문제를 해결 할 수 있기 때문에 교사의 도움을 크게 필요로 하지 않았다. 그러나 조 안에 인지수준이 높은 학생이 없거나 토론을 주도하지 못하는 경우에는 교사의 개입이 있어야 올바른 문제인식과 문제해결이 이루어 졌다. 위의 결과는 CASE와 같이 학생-학생, 교사-학생 상호작용이 중요한 부분을 차지하는 소규모 집단 토론학습에서, 인지수준이 다양한 모든 학생들이 적극적으로 학습에 참여하도록 하기 위해서는 인지수준이 높은 학생이 조 내에서 토론을 이끌도록 조를 구성하고, 인지수준이 낮은 학생들도 적극적인 사고활동을 할 수 있도록 조 구성원들 사이에서 메타인지적 질문이 오고가는 분위기를 조성하기 위한 교사의 적극적인 개입이 필요함을 시사한다.

Previous studies indicated that students tended to hold less satisfactory beliefs about the discipline of mathematics, beliefs about themselves as learners of mathematics, and beliefs about mathematics teaching and learning. However, only a few studies had developed curricular interventions to change students' beliefs. This study aimed to examine the effect of a problem-solving curriculum (i.e., Mathematical Problem Solving for Everyone, MProSE) on Singaporean Grade 7 students' beliefs about mathematical problem solving (MPS). Four classes (n =142) were engaged in ten lessons with each comprising four stages: understand the problem, devise a plan, carry out the plan, and look back. Heuristics and metacognitive control were emphasized during students' problem solving activities. Results indicated that the MProSE curriculum enabled some students to develop more satisfactory beliefs about MPS. Further path analysis showed that students' attitudes towards the MProSE curriculum are important predictors for their beliefs.

The objective of the present study was designed to examine that metacognition education had any promoting effects on the development of students' reasoning ability. Two classes in the 5th grade were asked to participated for the present study. Prior to the metacognition teaching, both the experimental and control group classes were given to the preliminary test in which students' basic ability for mathematical reasoning was graded. Then, the students in the experimental group were given 8hour teaching for the topics on the symmetric properties of geometric figures. The present findings indicate that educational application which motivates metacognition can improve mathematical reasoning ability in elementary students. It is widely accepted that metacognition is an active and conscious mental activity, helps the students perceive voluntarily the study items, and further plays an important role in constructing independent and active thinking processes. Accordingly, the present results implicate that the practical performance of metacognition education into the class indeed contributes to build up or strengthen students' voluntary ways of reasoning.

본 논문은 수학수업에서 점점 소외되고 있는 수학학습부진아가 대수학습에서 학업성취도를 신장시키기 위해 좀 더 나은 효과를 얻을 수 있는 방법을 모색하고자 하였다. 이를 위해 수학학습부진아를 선정하여 두 집단으로 나누었다. 한 집단은 처치집단으로 CAS 계산기를 사용하여 활동지를 학습하고, 다른 집단은 통제집단으로 지필을 사용하여 활동지를 학습하였다. 각 집단은 활동지를 통해서 메타인지 활동을 하였다. 수업 전과 후에 두 집단 모두 지필로 수학학업성취도를 실시하여 비교 분석한 결과, 처치집단이 통제집단보다 여러 가지 측면에서 더 나은 효과를 나타내는 것을 확인하였다.

Computer Assisted Learning (CAL) is quite different from in many aspects. CAL provides individualistic learning environment and facilitates autonomy of the learner. Thus the learners who uses CAL program has more sense of control and engages in more strategic learning than conventional learning environment. In this experiment, we used KORI (KORea university intelligent agent) which is a new type of ITS adopting TA (Teachable Agent) that fosters learning by teaching, So, we investigated the critical motivational factor that have influences in CAL learning and the effects of reward in CAL are another area of our interest. Thus, we divided two conditions that presence of reward and absence of reward. The 174 elementary school students(5th) were participated and they are randomly assigned the one of the reward conditions. Before entering the experimental instruction, all participants measured about metacognition, self-efficacy and goal orientation questionnaire as independent variables. Then, Participants were instructed of method of using KORI program and asked to study for ten days with KORI program at least 20 minutes everyday in their home, about 10 days. After 10 days, they were rated interest and comprehension. Regression results suggest that regardless of the presence of reward, metacognition is a positive predictor in interestingness. It indicate that metacognitive skills are required in CAL learning situation irrespective of reward. But on comprehension in the absence of reward, only self- efficacy appeared to be a positive predictor. In the presence of reward, performance goal orientation showed as a negative predictor of comprehension, whereas self-efficacy was a positive predictor. This result suggest that presence of reward especially interferes learning process of performance goal orientation in CAL learning situation. It could be interpreted that reward interferes the learning process of performance goal orientation by debilitating intrinsic motivation.

The research paper presents the results of an experimental research of the development of critical thinking in third-year students majoring in 013 "Primary Education" in studying a special course "From Reflection to Self-Assessment: Critical Thinking Skills" (based on Lauren Starkey methodology). The research was conducted during the first half of 2019-2020 academic year. The sample representativeness was ensured by the method of random selection, the strategy of randomization according to the criteria of age, gender, level of academic performance was described. Given the confidence interval p=95% and the confidence interval of the error Δ=±0.05, the sample size was 94 people, including of the experimental group and 49 students of the control group. The peculiarities of the development of such critical thinking skills as reflective thinking, self-analysis, awareness of one's own achievements and shortcomings, choice of problem-solving strategy, use of cognitive models of learning are revealed. It was found that the development of critical thinking was achieved through a comprehensive combination of self-assessment and reflection, performing exercises to develop the ability to clearly articulate the problem, find, analyse and interpret relevant information, draw the right conclusions and explanations.
