The Effect of Inquiry Program Based on Growing Lettuce Applicable to Discretionary Activities on Basic Inquiry Skills of Lower and Upper Elementary Students Children
본 연구는 상추 기르기 과학 탐구 프로그램을 초등학교 재량활 동시간에 적용하여 저학년과 고학년의 기초탐구능력에 미치는 영 향을 알아보고자 수행되었다. 이를 위하여, 초등학교의 2, 5학년 각 1개의 학급씩 실험군과 대조군으로 나누었고, 실험군에는 재량활 동시간을 활용하여 상추 기르기 과학 탐구 프로그램이 제공되었다. 실험군의 상추 기르기 활동에 기초한 원예-과학 통합프로그램 시 행 후, 저학년과 고학년 모두 기초탐구능력 총점이 사전보다 각각 3.89, 1.76으로 증가하였고, 저학년이 고학년과 비교하면 2.13점 더 향상되었다. 저학년의 기초탐구능력 하위 요소별 사후 검사 결 과, 대조군은 관찰을 제외한 분류, 측정, 추리, 예상에서 유의차 없 이 향상되었으나, 실험군은 사후 검사결과 관찰, 분류, 측정, 추리, 예상 모든 탐구요소에서 유의하게 향상되었다. 고학년의 기초탐구 능력 하위 요소별 사후 검사 결과, 실험군은 분류와 추리 영역에서, 대조군은 분류 영역에서 유의한 증가가 나타났다.
This study has a purpose to research the effects of 'Horticulture-science integrated program based on growing lettuce' on basic inquiry skills for lower and upper grades of elementary school. For this purpose, the class of the second and fifth grade students was divided into a control group and a experimental group respectively. In the experiment group of second and fifth grades, the horticulture-science integrated program was provided for total eight times, one hour thirty minutes each from 1:00 to 2:30 pm every week, through the discretionary activity time from September 11 to November 6 2012. After being offered horticulture-science integrated program based on growing lettuce, total basic inquiry skills score of both lower grades and upper grades are increased by 3.89, 1.76, respectively. Total basic inquiry skills score of the lower grades had 2.13 point higher improvement compared to the upper grades. Control group of the lower grades had improvement on classification, measurement, inference, expectation parts except observation with no significantly(p>0.05). However, the experimental group of lower grades improved in all search factors of observation, classification, measurement, inference, and expectation as the result of post test. As the result of implementing the t-test to find out any statistical implication, there was a significant difference(p<0.01). As the result of post test, the experimental group of upper grades improved significantly in search factors of classification and inference and the control group of upper grades improved significantly only in search factors of classification.
