Since the term, 'scientific literacy' was introduced by P. D. Hurd in 1958, it has been used as a term, representing major goals in science education. In Korea, the term 'scientific literacy' was used in the statement of the summative objective of the 2007 science reformed curriculum. But in various educational contexts m which teachers and researchers works, the definition of the term has not been used consistently. This phenomena would be interpreted as showing limits of the term describing the goals of science education. This study examined the historical change in the meaning of the term in purpose of trying to anchor the definition. In this study, the changing period was divided into before introducing the term and after. The after era was divided into the period of confusing and anchoring in the meaning, and the period of expanding the meaning. Especially, after science as intellectual ability was conceptualized in science education communities, the meaning of scientific literacy was partially confused. In current time, as the concepts of language in cognitive science influenced the use of language in science education, the trends of expending the meaning of scientific literacy has been grasped in science education community.

The purpose of this study is to apply the PEOE class model that can enhance students' scientific creative problem-solving ability and self-directed learning ability in the middle school science subject and analyze the effects of it on students' long- and short-term retention, scientific creative problem-solving ability, and self-directed learning characteristics. And the paper has gained the following results: First, according to the result of analysis through the pre-test, post-test, and delay test to examine the effects of PEOE-based class on learners' long- and short-term retention, it is found to be statistically significant in the significant level of .05. In other words, the class using PEOE influences learners' short-term retention significantly, but it is even more effective in transmitting the concept that students acquire into their long-term memory. Second, according to the result of analysis through the pre-test and post-test to examine the effects of PEOE-based class on learners' scientific creative problem-solving ability, it is found to be statistically significant in the significant level of .05 in general. However, 'elaboration' and 'originality', the subfactors of scientific creative problem-solving ability, do not indicate significant effects. Third, according to the result of analysis through the pre-test and post-test to examine the effects of PEOE-based class on learners' self-directed learning characteristics, it is found to be statistically significant in the significant level of .05 as a whole. However, 'openness' and 'future-oriented self-understanding', the subfactors of self-directed learning characteristics, do not exert significant effects. Based on the above study results, it can be concluded that PEOE-based class is more effective for learners' academic achievement in science, scientific creative problem-solving ability, and self-directed learning characteristics than lecture-method instruction regarding the middle school science unit of 'The Properties of Air and Weather Change'.

The purpose of this study is to develop a valid and reliable instrument of the performance assessment that is can evaluate the scientific inquiring ability. The characteristics of the instrument developed through this study, are as follows, 1. The performance assessment can be impartially achieved for all the elements of scientific inquiry, which are required in the units of elementary science from 3rd to 6th grade of elementary school. 2. To maintain the objectivity of performance assessment, the detailed standpoints and standards are established. 3. The instruments are devised to evaluate the thinking skills with the experimental reports of student, the operation skills by the check list of evaluation that the teacher's observation for the student are recorded. 4. Considering the level of elementary school student, the items required the complex thinking and the investigative skills are exclude as much as possible. 5. The items are arranged according to the learning steps of elementary school, so that the evaluation may be achieved in parallel with the process of the real teaching -learning in class. 6. According to circumstances, make use of these materials for the evaluation as the practical teaching-learning materials instead of the normal teaching-learning materials The first field trial with the instrument was carried out, using a sample of 20 students from the 3rd to 6th at K and Y elementary school located in Kwangju city. The results of mean achievement quotient for each grade are as follows, the first term of 3rd grade (experiment and exercise skills ; 85%, inquiry thinking skills ; 74%), the second term of 3rd grade (experiment and exercise skills : 81%, inquiry thinking skills ; 76%), the first term of 4th grade (experiment and exercise skills ; 70%, inquiry thinking skills ; 59%), the second term of 4th grade (experiment and exercise skills ; 61%, inquiry thinking skills ; 71%), the first term of 5th grade (experiment and exercise skills ; 84%, inquiry thinking skills ; 67%), the second term of 5th grade (experiment and exercise skills; 73%, inquiry thinking skills ; 70%), the first term of 6th grade (experiment and exercise skills : 83%, inquiry thinking skills ; 84%), the second term of 6th grade (experiment and exercise skills ; 87%, inquiry thinking skills ; 81%).

This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.

Correct comprehension of the scientific terms is the bottom of understanding the general concepts contained is them. Therefore a study is required to analyze whether the students correctly understand the scientific terms. The associative method was used to evaluate the comprehensibility of the terms. The scientific terms in this study are selected in the textbook of science in the junior high school were selected. The frequency of the same associative word responsed and the frequency of no response from the selected students for given scientific terms were measured for 9 different groups. The terms which are not used in the daily life, especially for the terms with chinese character or abstract terms turn out to be difficult for the students to understand. It is purposed that the instructor should remember the importance of understanding the scientific term and carefully explain them to the science class.

Firstly, the author suggests a new term of the "Pro-Engineer's Doctrine" on every engineering work. This renewed term should be in their minds who are doing any kinds of scientific and technological works in his/her field. The term, "doctrine", is based on a wise sage, renewedly, so-called "The Way of the measuring squire(혈矩之道)" saying in one of the Oriental classics. Also, he explains here another term, "Investigation of things, attainment of knowledge(格物致知)" that is very similarity to the "Pro-Engineer's Doctrine" from the same book.

Schools are one of the critical social infrastructures in a society, the first place for social activity and the most important indoor environment for children besides the home. Poor IAQ in classrooms can increase the chance of long-term and short-term health problems for students and staffs; affects productivity of teachers; and degrade the student learning environment and comfort levels. The primary objective of this paper is to review and summarize available scientific evidence on indoor air quality of schools and related health effects in children. It was found that the indoor air pollutant levels in school buildings varied over a wide range in different parts of the world depending on site characteristics, climatic conditions, outdoor pollution levels, occupant activities, ventilation type and building practices. Among the indoor air pollutants, particulate matter concentrations were found to be very high in many schools. Outdoor pollutant sources also play a major role in affecting the IAQ of the school building. Hence, scientific knowledge on sources of indoor pollutants, quantification of emissions, temporal and spatial dispersion of pollutants, toxicological properties, chemical and morphological characteristics of the pollutants and associated health risk among children in the school buildings are essential to evaluate the adequacy and cost effectiveness of control strategies for mitigating the IAQ issues.
