  • Researchers continue to emphasize the centrality of proof in the context of school mathematics and the importance of proof to student learning of mathematics is well articulated in nationwide curricula. However, researchers reported that students' performance in proving tasks is not promising and students are not likely to see the need to prove a proposition even if they learned mathematical proof previously. Research attributes this issue to students' tendencies to accept an empirical argument as proof for a mathematical proposition, thus not being able to recognize the limitation of an empirical argument as proof for a mathematical proposition. In Korea, there is little research that investigated high school students' views about the need for proof in mathematics and their understanding of the limitation of an empirical argument as proof for a mathematical generalization. Sixty-two 11th graders were invited to participate in an online survey and the responses were recorded in writing and on either a four- or five-point Likert scale. The students were asked to express their agreement with the need of proof in school mathematics and to evaluate a set of mathematical arguments as to whether the given arguments were proofs. Results indicate that a slight majority of students were able to identify a proof amongst the given arguments with the vast majority of students acknowledging the need for proof in mathematics.

  • This article explored the perceptions of ‘family’and the factors related to respondents' definitions of a family. The data were collected from two types of people: one was 472 university students and high school students' parents who were asked whether or not each of 22 scenarios represented a‘family’, and the other was 40 young and middle-aged adults who were asked,“what is a family member?”. Results showed that (1) the overwhelming majority of respondents considered a married couple without a child(scenario #5) as a family and the least respondents agreed a divorced couple(scenario #18) as a family, (2) the majority perceived consanguinity, co-residence, parental status, and marital status to be important in the definition of a family, (3) middle-aged adults were more likely than young generation to agree that consanguinity and paternal relations were important in determining what a family member is.

  • The objectives of this study were to determine the preferences and consideration factors for selecting processed foods, in middle school students as well as their perceptions on food and nutrition labeling student. Middle school students in the Seoul area were surveyed from October to November, 2006. The results are summarized as follows: the preferred processed foods included 'drinks' (3.85), 'noodles' (3.81), 'biscuits and bread' (3.80), 'milk and dairy products' (3.71), and 'meat and meat products' (3.60). The most important consideration factors in selecting processed foods were 'expiration date' (4.45), 'taste' (4.34), and 'price' (4.08). The two main reasons for eating processed foods were 'delicious' (43.1%) and 'convenient' (33.9%). Food labels were identified 'sometimes' (34.5%), 'rarely' (31.2%), and 'almost never' (18.6%). The primary reason for examining a food label was 'to confirm the expiration date' (52.6%). The main reason for not reviewing a food's label was 'habitual purchase' (57.8%). Nutrition labels were identified 'rarely' (33.4%), 'almost never' (24.7%), and 'sometimes' (23.5%). The reasons for examining nutrition labels included 'to confirm a high proportion of nutritive substances' (26.5%), 'boredom' (24.2%), 'for weight control' (23.5%), and 'to improve health' (18.1%). The main reason for not examining a food's nutrition label was 'not interested' (56.5%).

  • The purpose of this study was to investigate differences in the perception and attitudes of middle school students toward food safety between those who possess high behavioral intentions to prevent contracting a foodborne illness and those who do not. The survey collected 871 usable data from several middle schools in Seoul, Korea in July 2007. Using six behavioral intention measurement items, a two-step cluster analysis approach was conducted resulting in a strong intention group and a weak intention group. Perception and attitudes toward foods safety were different between the two groups. Students with strong behavioral intentions to prevent foodborne illness tended to possess a stronger perception and attitude toward various food safety issues. Students with strong intentions were more certain of consumer's right to purchase safe foods, more concerned about foodborne illness and food safety, believed that the government should put more efforts toward establishing a safe food chain, possess more distrust for food suppliers, were more aware of specific foodborne illness pathogens, had more food safety education/training, and washed their hands more frequently than those with less strong intentions. No significant differences were found between the groups but,overall, chemical residues and food additives were perceived as more harmful and more serious food safety issues than those of foodborne illness pathogens despite that microorganisms are the main cause of foodborne illness outbreaks in schools. Participants seemed to underestimate the importance of temperature control for preventing foodborne outbreaks. Several implications and suggestions on how to improve the behavioral intentions of middle school students to prevent possible foodborne illness were provided.

  • 이 연구에서는 제7차 교육과정에 따라 개발된 중학교 과학 교과서의 구성과 접근 방식에서 STS를 어떻게 고려하고 있으며 교과서에서 다루고 있는 STS 내용에는 어떤것들이 있는지를 분석하고, 과학 교사와 학생을 대상으로 면담을 실시하여 수업에서 실제로 STS 교육이 어떻게 이루어지고 있는지를 살펴보았다. 교과서 구성이나 내용 면에서 종전에 비하여 STS가 강조되고 있으나, 주로 읽을거리 형태의 '과학의 응용', '사회적 문제와 논쟁' 내용에 편중되어 있어 보다 다양한 STS 접근과 STS 주제를 포함할 필요가 있다. 그리고 STS 내용에 대한 평가의 어려움, STS 교육에 대한 교사의 인식과 경험 부족, 그리고 학부모와 학생의 인식 부족 등으로 인하여 중학교 과학 수업에서 STS 교육을 실현하기 어려운 것으로 생각된다. 이상과 같은 연구 결과를 토대로 중학교 과학 수업에서 STS 교육이 실효를 거두기 위한 몇 가지 제언을 하였다.

  • The objective of this study is to investigate the perception and satisfaction of elementary and middle school students on free school food service. We surveyed education related to school food service, concerns about food ingredients, perceptions of free school food service and satisfaction for the quality of the school food service. The investigation is classified into two groups, schools that operate as a food service center or those that do not. Those who are provided food ingredients by school food service centers are educated about the agricultural products' country-of-origin and their environment-friendly food service. The more individuals are educated of the foods' county-of-origin and environment-friendly food service the more they will have a higher concern of the food materials and subsequently a higher satisfaction for the quality of school food service. School food service centers managed directly by the local government would probably receive higher satisfaction than those consigned to a private sector. The results of this study will be meaningful to establish policies on school food service and school food service centers.

  • 본 연구는 현재 기술 가정교과에서 이루어지고 있는 학교식생활교육에 대하여 중학생틀이 어떻게 인식하고 있는지 살펴보고자 하였다. 경기지역 중학교 3학년 남녀학생을 대상으로 설문조사를 실시한 바, 유효응답자 444명 중 78.1%가 주로 기술 가정교과로부터 식생활 관련 지식과 정보를 습득하고 있었으며, 62.6%가'실생활에 도움이 된다', 67.3%가 '학교식생활교육이 필요하다'고 응답하였다. 현재 시행중인 식생활교육지원법에 대해서 88.7%의 응답자가 모르고 있었다. 식생활교육영역을 총28개의 항목으로 세분화하여 질문한 결과, 전반적으로 관심도가 높은 항목일수록 실천도 역시 높은 것으로 나타났으며, 모든 항목에서 여학생이 남학생보다 높은 관심도 및 실천도를 나타냈다. '식사예절' 및 '청소년의 영양과 식사' 영역과 관련된 교육항목에 대한 관심이 높았으며 '식품 조리' 영역에 대한 관섬은 상대적으로 낮았다. 학교식생활교육의 필요성에 대한 학생들의 인식에는 '청소년의 영양과 식사' 단원에 대한 관심도가 가장 큰 영향을 미치는 것으로 나타났으며, 다음으로 성별, '식사예절' 단원의 실천도 등의 순으로 조사되었다.

  • 본 연구에서는 오프라인과 온라인으로 진행된 물리탐구 토론에 참여한 학생들을 대상으로 실시된 설문과 면담을 통하여 온라인 물리탐구토론 학습체제에 대한 학생들의 인식을 알아보고, 이를 통하여 온라인 물리탐구토론 학습 체제의 특징을 알아보았다. 분석은 온라인 물리탐구토론 학습체제의 사용자 편리상 온라인 탐구토론의 비동시성, 글쓰기와 관련된 온라인 탐구토론, 온라인 탐구토론의 시각적 표현과 물리적 존재감, 온라인 탐구토론의 선호도의 다섯 가지 범주로 실시되었다. 학생들은 온라인 탐구토론에서 시공간을 초월하여 접근할 수 있고, 비동시성으로 인하여 충분한 사고 후에 논쟁에 참여할 수 있다는 점을 온라인 탐구토론의 가장 큰 장점으로 여기고 있었다. 또한 온라인 활동이 학생들 스스로의 참여로 수행되지만, 학생들의 활발한 참여를 위해서는 온라인 교육 시스템의 기술적인 부분이외에도 학부모와 교사의 역할이 더없이 중요하다.
