지적장애 학생을 위한 문제중심학습(PBL) 적용 가정과 식생활 교수･학습 과정안 개발과 평가 = Development and evaluation of Home Economics teaching·learning process plans applied Problem Based Learning focusing on ‘food and nutrition’ unit for students with intellectual disability

다국어 초록 (Multilingual Abstract)

The purpose of this study was to develop Home Economics(HE) teaching and learning process plans applied Problem Based Learning(PBL) focusing on ʻfood and nutritionʼ unit for students with intellectual disability and to evaluate the effects of the HE instruction on their food choice･management knowledge and problem-solving skills after implementing the instruction for students with intellectual disability. To develop HE teaching and learning process plans applied PBL focusing on ʻfood and nutritionʼ unit for students with intellectual disability, problems that arise in daily life to trigger interest of students were firstly developed. The selected problems and teaching and learning process plans were reviewed for validity by one home economics education professor and three teachers who are experts in special education.
This study used the one group pretest and posttest design, sampling 6 students who are in special-education middle school with the intellectual disability. After HE instruction of 6 sessions applied PBL method, this study tested the effects of the instruction. The first three sessions taught how to choose and keep food. The fourth session taught purchasing food ingredients and keeping them for sandwiches. The fifth and sixth sessions let the students make sandwiches and give them to others.
The instruments of the study comprised of tools for food choice and management knowledge, tools for problem-solving skills evaluation, self-evaluation sheets, evaluation form of course satisfaction for students, evaluation form of behavior in class for teachers, and daily observation journal and all tools. These instruments were proved to have reliability and validity.
The results of this study are as follows. First, all six students who took HE instruction applied PBL method focusing on ʻfood and nutritionʼ unit scored 30 points higher out of 100 points after taking the instruction in food choice and management knowledge and scored 5 points higher out of 14 points in problem-solving skills on average. Therefore, it was interpreted that HE instruction applied PBL affected the food choice･management knowledge and the problem solving skills of students with intellectual disability. Secondly, the students with intellectual disability participated actively in HE instruction applied PBL focusing on ʻfood and nutritionʼ unit and expressed satisfaction. Three special education experts evaluated HE teaching･learning process plans applied PBL focusing on ʻfood and nutritionʼ unit to be well-developed. This study showed that HE instruction applied PBL focusing on ʻfood and nutritionʼ unit allowed the students with intellectual disability to acquire comprehensive skills in choosing, keeping, and making safe food and helped them solve problems of their life by themselves. Therefore I suggest that Home Economics should be adopted as a formal subject matter in special school curriculum for students with intellectual disability.

국문 초록 (Abstract)

최근 일반교육 교육과정을 통해 장애학생의 성인생활 자립 역량을 갖추어야 한다는 목소리가 높다. 일반교과인 가정교과는 사명지향적인 학문으로써 장애학생들의 개인생활과 가정생활에 도움을 줄 수 있다. 가정교과에서 식생활 교육은 학생들의 자립성과 사회성을 향상시키면서 식생활 교육과 식생활 연구가 부족한 특수교육 상황에 효과적으로 활용될 수 있다. 이에 본 연구의 목적은 문제중심학습(problem based learning: PBL)을 적용한 가정과 식생활 교수･학습 과정안을 개발하여 지적장애 학생들에게 수업을 실행한 후 이 수업이 식품 선택과 보관 지식과 문제해결력에 미치는 효과를 알아보는 데 있다.
본 연구는 단일 집단 사전-사후 설계로 연구 대상은 지적장애 특수학교 중학과정에 다니는 학생 6명으로 편의 표집하였다. 이들 학생들에게 PBL을 적용한 가정과 식생활 수업을 6차시 실행한 후 이 수업의 효과를 알아보았다. 1∼3차시 주제는 식품 선택과 보관 방법이고, 4차시 주제는 샌드위치 재료를 구입하여 보관하는 것이며, 그리고 5∼6차시 주제는 샌드위치를 만들어 선물하는 것이다.
지적장애 학생을 위한 PBL 적용 가정과 식생활 교수･학습 과정안을 개발하기 위해서 먼저 학생의 흥미를 유발하며 실생활에서 충분히 발생할 수 있는 ‘문제’를 개발하였고 이 문제를 해결하는 수업 과정과 학습 자료를 제작한 후 가정교육학 교수 1인과 특수교육 전문가인 교사 3인으로부터 선정된 문제와 개발된 교수･학습 과정안의 타당도 검증을 받았다.
수업 효과를 알아보기 위한 측정도구는 식품 선택과 보관 지식 평가 도구, 문제해결력 관찰 평가와 학생용 자기평가 도구, 학생 수업만족도 평가지, 교사의 수업행동 평가지, 수업 관찰 일지로 구성되며 이 도구들은 신뢰도와 타당도를 검증 받았다.
본 연구의 결과는 다음과 같다 첫째, PBL을 적용한 가정과 식생활 수업을 받은 6명 학생 모두가 100점 만점인 식품 선택과 보관 지식 점수에서 사전보다 사후에서 평균 30점 높아졌고 14점 만점인 문제해결력 점수는 사전보다 사후에서 평균 5점 더 높아졌다. 따라서 이 수업은 지적장애 학생들의 식품 선택과 보관 지식과 문제해결력에 효과를 미친다고 볼 수 있다. 둘째, 지적장애 학생들은 PBL을 적용한 가정과 식생활 수업시간에 열심히 참여하였으며 이 수업에 만족감을 느꼈다. 특수교육 전문가인 교사 3인은 이 수업에 대해서 실습을 위한 수업 준비 시간이 오래 걸린 점이 다소 아쉬웠지만 교수･학습 과정안이 타당하게 철저히 준비되었고 학생 간 상호작용이 적절하였으며 문제중심학습 수업 흐름에 맞는 진행을 하였다고 평가하였다. 이 연구를 통해 PBL을 적용한 가정과 식생활 수업은 지적장애 학생들이 식품 선택과 보관부터 안전하고 건강한 음식을 만드는 종합적인 식생활 기술을 습득하여 일상생활에서 발생할 수 있는 식생활 관련 문제를 스스로 해결하는데 도움이 되었다고 사료된다. 따라서 전국의 특수학교의 장애학생들에게 PBL을 적용한 가정과 식생활 수업뿐만 아니라 의생활, 주생활, 소비생활, 아동･가족생활, 자원관리 전 영역을 다루는 가정교과가 특수학교에서 정식교과로 도입되기를 제언한다.
