Large Midwest university faculty members proposed the Science and Technology Enhancement Program Project (STEP) to improve students' learning in the secondary mathematics classroom using modules of inquiry-based teaching. The purpose of this study was to determine the impact of the STEP Project on students' attitude toward mathematics. Hierarchical linear models (HLM) were used to evaluate the impact of the STEP Project. The sample group for the study was 130 ninth grade students enrolled in Integrated Algebra I in a large urban school district. The school was one of eight secondary schools that participated in the STEP Project. The classes in the treatment group were three of five classes ordered in terms of the highest, middle, and lowest mean GPA. The control group consisted of two other middle GPA classes. The classes had an average of 25 students. Teachers who previously had been involved in the STEP Project taught all treatment and control classes. The inquiry-based teaching activities provided by the project were confined to the treatment classes. The survey measuring students' attitudes toward mathematics were obtained for both groups of students. The inquiry-based teaching affected students' attitudes toward mathematics (p < 0.07, ES = 3.07). Especially, students who had preexisting low attitudes toward mathematics were significantly affected by treatment (p < 0.02, ES = 0.02), while the treatment positively affected African American students overall at p < 0.08 (ES = 0.58).

이 연구에서는 데이터 기반 과학탐구에서 탐구활동과 협력적 문제해결력에 대한 초등학생들의 인식을 알아보고자 하였다. 이를 위해 경남 소재 도시의 초등학생 고학년 26명을 대상으로 20차시의 데이터 기반 과학탐구 수업을 진행하였다. 학생들은 탐구 문제를 선정한 후 디지털 탐구도구로 데이터를 수집하는 탐구 과정을 수행하였다. 수업 후 인식 조사 설문과 면담을 통해 다음과 같은 결과를 얻었다. 첫째, 학생들은 데이터 기반 과학탐구에서 '탐구 설계 및 수행' 단계가 가장 유익한 것으로 인식하였다. 둘째, 학생들은 데이터 기반 과학탐구를 통해 과학적 능력과 협동심이 향상되었고, 탐구문제 선정이 가장 어렵다고 인식하였다. 셋째, 학생들은 협력적 문제해결력의 향상에 대해 긍정적으로 인식하였다. 이상의 결과로부터 데이터 기반 과학탐구는 초등학생들의 과학적 탐구능력과 협력적 문제해결력 향상을 위해 필요함을 알 수 있었다. 이 연구를 바탕으로 다양한 탐구활동의 개발과 연구를 통해 미래를 살아갈 학생들에게 필요한 다양한 역량들을 함양할 수 있는 탐구 기회가 제공되기를 기대한다.

The purpose of this study is to examine the effects of Jigsaw small inquiry method on science academic achievement and scientific attitudes. For this study, two classes of six graders were divided into a research group and a comparative group. The classes were pre-tested in order to ensure the same standard. The research group had the science class with Jigsaw small inquiry method, and the comparative group had the class with a teacher centered lectures for 12 classes for 12 weeks. The Jigsaw small inquiry method was focused on the introduction stage, the whole group activities, professional group activities, restart the whole group activities, supplementary structured study guide, results announced, and excellent group rewards. To prove the effects of this study, science learning motivation was split up based on the attention power, relation, confidence, and sense of satisfaction. The results of this study are as follows. First, Jigsaw small inquiry method is effective in science academic achievement. Second, Jigsaw small inquiry method is effective in scientific attitudes. Also, Jigsaw small inquiry method was approved by students. Consequently, Jigsaw small inquiry method had the great effects on developing science academic achievement for the elementary science class. That means the science class with Jigsaw small inquiry method has potential to develop science academic achievement and scientific attitudes.

지구과학 탐구 대상은 다른 학문의 탐구 대상과 달리 거대한 시 공간적 규모, 접근 불가능성, 통제 불가능성, 복잡성 등을 지니고 있다. 그렇기 때문에 지구과학의 탐구 대상을 실험실 내에서 실제 조작을 통해 탐구하는 것은 매우 어렵거나 심지어 불가능하다. 따라서 지구과학에서는 실제 조작을 하지 않고도 탐구를 할 수 있는 대안이 필요하다. 실제 조작을 하지 않고 탐구를 수행하는 대표적인 탐구인 사고실험으로부터 추론의 역할을 재조명하고 추론을 사용한기존의 탐구 수업 모형들의 특징을 조사하였다. 각 탐구 모형들을 지구과학에 적용하는데 있어서의 시사점을 살펴보고 이들을 바탕으로 지구과학적 현상의 탐구에 적합한 추론 중심 탐구수업 모형을 제안한다.

This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.

The purpose of this study was to develop performance assessment materials of scientific inquiry skills on sixty scientific activities in elementary science textbook for fifth and sixth grades. For this study, a total of 500 elementary teachers were sampled and surveys were carried out to examine the status of performance assessment of scientific inquiry skills in school. The classification system of assessment methods by Hart(1994) was also analyzed to create' assessment strategy of scientific inquiry skills' for elementary school students. Based on the quantitative data analysis and literature study, performance assessment materials were developed and applied to science classes for fifth and sixth grades. Teachers and students were interviewed after the classes for asking about merits and improvements and the performance assessment materials were revised. This study can provide elementary school teachers with reliable sources for performance assessment of scientific inquiry skills utilized in their science classes.

The purpose of this study is to diagnose difficulties and problems that the preservice teachers experience when teaching inquiry-based classes in elementary science and to improve their professionalism through prescriptive instruction consulting utilizing PDRE (preparation, diagnosis, reflective implementation, evaluation) model. The result of this study was as follows. First, preservice teachers considered themselves to be lack of scientific knowledge, but this study confirmed that the application of instruction consulting improved their understandings in scientific concepts and principles and corrected their misconceptions. Second, preservice teachers experienced difficulties in variables that might influence the results of experiments, cautions for the experiments and unexpected results of experiments, and this consulting allowed them to gain instruction ability to cope with such circumstances and solve problems effectively. Third, preservice teachers experienced difficulties in applying instructional model into their classes and preparing lesson plans, but consulting actually made limited but positive changes in their abilities. However, from a longer-term perspective, quantitative increase in their teaching opportunities, the development and distribution of example manuals, and the utilization of various class materials provided by the assistant centers for teaching and learning should be achieved side by side.
