메타인지 훈련이 정신지체학생의 수학문제해결과 학습태도에 미치는 영향
이영철,정춘순 한국정신지체아교육학회 2002 지적장애연구 Vol.4 No.-
이 연구는 메타인지 훈련이 정신지체학생의 메타인지 수준과 수학문제해결에 미치는 영향을 연구하고자 하였으며, 메타인지 훈련 사전ㆍ사후 정신지체학생의 수학학습태도에 미치는 영향을 알아보고자 하였다. 연구결과 대상학생에 따라 메타인지 훈련이 미치는 영향이 각각 다르게 나타났으나, 메타인지 훈련은 정신지체학생의 메타인지 수준과 수학문제해결에 긍정적인 영향을 미치는 것으로 나타났다. 그리고 메타인지 훈련결과에 따른 정신지체학생의 수학학습태도도 긍정적인 쪽으로 변화된 것으로 나타났다. This study is to investigate influences of metacognitive training on the metacognition level, mathematics problem solving abilities and learning attitudes of students with mental retardation. The subjects were three middle students with mental retardation at H special school in Jeonbuk. The results of this study are as follows. First, metacognitive training was effective in improving the metacognitive level of the subjects. According to the test of individually metacognitive levels, student 1 and 3 increased at metacognition level. Student 2 showed an increase in his cognitive strategies and self-examination with the exception of planning. The reason is that the subject was exposed to self-controlling activities in the process of problem solving, the provision of metacognitive knowledge and strategic monitoring among metacognitive training. Second, metacognitive training was effective in enhancing the mathematics problem solving abilities of students with mental retardation. The pretest and posttest of mathematics problem solving abilities showed that student 1 and 3 were highly influenced in terms of self-examination. Student 2 was influenced in terms of understanding and performing abilities with the exception of self-examination. The reason is that performing abilities capable of solving practical problems by means of offering the process of problem solving on a gradual basis through self-instruction, self-questioning, and self-monitoring among the process of metacognitive training. Third, metacognitive training turned out to have a positive influence on the subjects' attitudes. In terms of mathematics learning attitudes, student 1 and 2 weren't greatly influenced after metacognitive training, but such training gave them confidence in mathematics. Student 3 concentrated on the problem and was willing to try a variety of methods on a gradual basis when solving problems.

Solidification analysis of shaped castings and prediction of shrinkage cavity formation by the finite difference method were demonstrated with several examples. Several actual castings of aluminum alloy in sand mold wore experimented and the results were compared with those obtained by computer simulation. The two prediction parameters, temperature gradient and critical fraction solid for fluid flow, and an auxiliary parameter shrinkage potential, were adopted for predicting the formation of shrinkage cavity or porosity in aluminum alloy castings. It was found that a quantitative design of shaped castings can be made by the computer aided solidification analysis.
