During the period of rapid industrial growth, specialized high schools were important vocational education institutions trained specialists and technicians. But now, specialized high schools turned into high schools where the low-ranking students who were pushed out of the competition for admission due to a decline in the education population, changes mostly in labor demand in the labor market, and discrimination against skilled workers. In order to solve this problem, the middle school 3rd grade teachers in charge of the middle school can provide early career guidance, so that they can decide to go to the specialized high school according to their aptitude and talent rather than their grades. The purpose of this study is to investigate the relationship between general characteristics and perception of middle school 3rd grade teachers, and the rate of decision to enter specialized high school. In 2018, The middle school 3rd grade teachers in charge in Daejeon metropolitan city were selected. The results of this study were as follows: When 3rd grade teachers in charge are the male teachers 21.01%(M=.2101) of their students go to specialized high schools. When they are teachers who have not graduated from college of education(M=.2110), with doctoral degree(M=0.3064), of their students go to specialized hight schools. Finally, there was a significant positive relationship between perceptions of high school teachers (β1 = .245, p = .000) and high school graduates (β2 = .149, p = .027). The regression equation derived from this is y = -0.56 + 0.037 * β1 + 0.025 * β2 10.1% (R² = 0.101).

There have been several studies regarding strict and formal proof in the field of geometry in middle school curriculum, and the level of proof has been gradually lowered along with the changes in the curriculum. In the 2011 Revised Middle School Math Curriculum, there have been efforts to eliminate the term 'proof' and instead to replace it with the new one, 'justification'. Therefore, this study intends to present specific and practical examples of justification by analyzing the current math textbook especially in the field of geometry. As a result, it identified that strict and practical proof has been sharply increased in the second year of middle school. It also witnessed the possibility of justification from the various examples presented in the first, second, and the third year of the middle school math textbook.

이 연구는 중학교 과학 수업의 온 오프라인 혼합 협동학습에 대한 효과를 검증해 보고자 하였다. 연구의 목적을 달성하기 위해 먼저 온 오프라인 혼합 협동학습과 관련된 문헌 고찰을 통해 연구의 수행에 필요한 이론적 기반을 마련하였다. 중학교 1학년 과학 내용 중에서 연구 단원을 선정하여 온 오프라인 혼합 협동학습 모형을 제시하였다. 연구대상은 경기도 김포시에 위치한 'K'중학교 1학년 학생들 중에서 사전 학업성취도 검사와 학습태도 검사에 의해 동질집단으로 확인된 2개 학습 79명이다. 연구대상 중 1개 학습 40명을 실험대상으로 선정하여 온 오프라인 혼합 협동학습의 실험을 실시하고 통제집단에는 기존의 면대면 협동학습을 실시하였으며 실험이 끝난 후 두 집단의 학업성취도 및 학습태도 변화 차이를 비교 분석하였다. 결과 분석은 SPSS Ver.12.0을 이용하였으며 학업성취도는 다변량 분산분석(MANOVA)을 하였고, 학습태도는 독립표본 t검정을 통해 분석하였다. 분석한 연구의 결과 첫째, 중학교 과학 수업에서 온 오프라인 혼합 협동학습은 면대면 협동학습과 학업성취도에서 유의미한 차이가 나타났다. 또한 온 오프라인 혼합 협동학습 실험집단이 면대면 협동학습 통제집단보다 학업성취도의 하위 영역 중 기억 영역에 그 효과성이 두드러짐을 확인하였다. 둘째, 중학교 과학 수업에서 온 오프라인 혼합 협동학습은 면대면 협동학습과 학습태도에서 유의미한 차이가 나타나지 않았다. 연구 결과를 토대로 온 오프라인 혼합 협동학습은 첫째, 학습자들로 하여금 자료 수집, 분석, 정리 단계에서 정보의 공유를 통해 적극적으로 학습을 유도하였다고 예측할 수 있다. 이는 온 오프라인 혼합 협동학습이 면대면 협동학습보다 학업성취도 향상에 효과적인 교수학습 방안으로 제시될 수 있음을 의미한다. 둘째, 중학교 과학수업에서 온 오프라인 혼합 협동학습은 학습자의 학습태도에 효과적이라고 확신할 수 없다. 따라서 학습자의 교과에 대한 학습태도의 향상을 위해서는 교수 학습방법을 다각화하고 교과와 학습목표에 맞는 적절한 학습방법의 지속적 활용이 중요하다고 판단된다.

The Purpose of this study was to investigate the relationship between elementary and middle school students’ depression and their mothers’ parenting stress. The subject were 659 elementary and middle school students and their mothers. In the study, elementary and middle school students depression appeared significant difference to their sex/grade. Parenting stress related to learning expectation appeared significant difference to elementary and middle school students’ sex/grade. Elementary and middle school students depression appeared significant difference to Parenting stress. And as for correlating parenting stress to elementary and middle school students’ depression, the significance appeared in these factors.

This study compared and analyzed the van Hiele levels of geometry contents in middle school mathematics textbooks and those of students' thinking. As the mathematics curriculum was revised recently, the amount of contents in the geometry area were reduced, but the van Hiele level did not change much, and the gap between the van Hiele level of geometric contents presented in the textbooks and the level of students' geometric thinking still remained unchaged. The van Hiele levels of the geometric contents in the textbooks were distributed in the levels of 1, 2, 3 in the first grade, and 2, 3, 4 in the second and third grade. In the case of the first grade, 69% of the students were less than or equal to level 2, and 73.7% and 47.6% of the students in the second and third grades were less than or equal to level 3, respectively. Especially, in the case of the second and third grade, the ratio of the 4th level of the contents presented in the textbook is higher than the problem, which can cause difficulties for the students.

This study examined career maturity of primary and middle school students who were interested in teaching job and compared to those who were interested in being a doctor. Using the data from the Korean Education Longitudinal Study 2013, we examined changes in the number of students (primary 5 through middle 2) who were interested in teaching as a job as well as in being a doctor. In addition, the participants' career maturity such as self-understanding, career planing, and attitudes towards job were examined and independent sample t-tests were conducted to compare two groups of students. Overall, the students who were interested in teaching showed lower level of career maturity compared to those who expected to be a doctor. Additionally, as students advanced to higher grades, the points of career maturity had been decreased regardless of which job they were interested in. Based on the findings, suggestions will be made to broaden the pool for future teachers.
