This study was to analyze the educational objectives of evaluation of practice quizzes and learning objectives of chemistry I textbooks for the 2009 revised curriculum by Klopfer's taxonomy. The result revealed that the objectives of science education indicated in the 2009 revised curriculum were contained the educational meaning of all categories except 'manual skills' of Klopfer's taxonomy of educational objectives. The learning objectives of chemistry I textbooks laid mostly on 'the knowledge and comprehension' and 'the process of scientific inquiry'. It showed that 'the objectives of scientific knowledge and methods', 'manual skills' and 'scientific attitude and interest', 'orientation' seemed to be taken in a relatively careless way. The result on the practice quizzes in textbooks, they also laid stress on 'the knowledge and comprehension' were covered much, even though they were emphasized in the other objectives of the curriculum. It was concluded that the educational objectives of the science textbooks did not reflect much on educational objectives of the 2009 revised curriculum.

Textbooks corresponding to curriculum goals are necessary because they are specific products of curriculum and are the most important materials for teaching, learning, and evaluation. In particular, learning objectives written in textbooks should be clearly described because they play a role in promoting learning by showing learning goals to learners clearly. This study analyzed the characteristics of verbs used as predicate of learning objectives written in high school physics I and II textbooks of Korea and compared them with physics textbooks of Singapore and the United States. Results show that Korean textbooks have less kinds of verbs compared to those of Singapore and the United States, and the verbs with abstract and comprehensive meaning such as 'understand' and 'know' were mainly used. In American textbooks, it was noticeable that no verbs have been used by more than 10%. When classifying the learning objectives in the two Korean textbooks, cognitive domain accounted for 98 to 99%, and inquiry domain accounted for only 1% to 2%. With regard to physics textbooks of the United States, inquiry domain accounted for a large proportion of domains in learning objectives compared with physics textbooks of Korea and Singapore. Physics textbooks of Singapore were similar to those of Korea in that learning objectives were biased toward cognitive domain, but differed from those of Korea in that learning objectives were specifically described using action verbs.

The purpose of this study is to analyze the learning objectives characteristics of educational programs of centers for the university affiliated science-gifted education using semantic network analysis, we examined the applicability of semantic network analysis in analyzing learning objectives by comparing the results of analysis with Bloom's revised taxonomy. For this purpose, 702 learning objectives presented in 169 science subjects were selected as subjects to be analyzed. After classifying and coding the learning objectives according to Bloom's revised taxonomy, we conducted a semantic network analysis to investigate the relationship between learning objectives. The results of the analysis are as follows. First, we looked at the number of learning objectives used for each subject, and about 3 elementary school levels and about 6 middle school levels were used. Second, the knowledge dimension such as 'factual and conceptual knowledge' and cognitive process dimension such as 'remember', 'understand', and 'create' was high regardless of the research method and school level. Third, the results of analysis based on the weighting through the semantic network analysis method, the elementary school level emphasize activities th be applied to the actual experimental process through learning about scientific facts, while the middle school level emphasize the understanding of scientific facts and concepts themselves. As a result, it can be seen that the semantic network analysis can analyze characteristics of various learning objectives rather than the conventional simple statistical analysis.

교사들의 생각하는 과학학습의 목표는 학생들이 생각하는 과학학습의 목표와 다를 수 있다. 과학을 잘 하는 모습은 교사의 입장에서 볼 때 과학교수 목표를 의미한다. 그러한 의미에서 과학교사들은 학생들이 과학을 잘 하게 하기 위해 과학 수업을 하고 있다고 볼 수 있다. 그러나 과학을 잘하는 모습은 교사마다 다를 수 있기 때문에 교사마다 다른 지향점을 가지고 과학교수활동을 하게 된다. 본 연구의 목적은 예비 교사들의 과학을 잘하는 모습에 대한 인식을 탐색하는데 있다. 연구를 위해 과학을 전공하고 있는 1학년에서 4학년 사이의 예비교사 30명을 대상으로 개방형 질문으로 구성된 설문을 실시하였다. 연구결과 예비교사들이 지닌 과학을 잘 하는 모습에 대한 인식의 유형과 과학을 잘 하는 모습을 결정짓는 상황의 유형을 분류할 수 있었으며, 예비교사들의 과학을 잘하는 모습에 대한 인식과 과학교수목표의 차이를 확인할 수 있었다.

The purpose of the study was to compare science curriculum documents of the several countries including Korea, the United States, the United Kingdom, Japan, and Singapore. The comparison focused on goals and contents in science education of each country. The goals for science education in each country were very similar. They included understanding knowledge, acquiring inquiry skills, developing positive attitudes towards science, and appreciating S-T-S in most countries. But each country's goal setting level was different; some countries set the same goals for several grades and other countries set different goals for each grade. Goals provided for each grade were more specific and elaborated. Science contents were categorized differently in each country. In Korea, science contents were categorized in energy, matter, living things, and earth. On the other hand, science contents were composed of 8 categories including unifying concepts and processes in science, science as inquiry, physical science, life science, earth and space science, science and technology, science in personal and social perspectives, and history and nature of science in the United States. In the United Kingdom, science enquiry, life processes and living things, materials and their properties, and physical process were categories for science contents. In Singapore, science contents were organized by themes relevant to students' everyday experience. Implications for goals and contents in science education to prepare students to live and work in a future society were suggested based on the results of the study.

This study is to reclassify the classifications or definitions of scientific literacy in scientific literacy researches since 1960s and grasp the classification trends of scientific literacy definitions. Sixteen articles have been selected among the articles that have been introduced in the two articles. Classification criteria are as follows: 1) "be learned," "competence," or "be able to function in society" as meanings of "literate," 2) "terms" or "description" as the ways of representing scientific literacy, 3) "singular structure," "hierarchical structure," or "parallel structure" as the inner structure of scientific literacy definitions. The results of this study are as follows: First, hierarchical structures in scientific literacy have almost always accompanied "terms" representing scientific literacy and also accepted the hierarchy between "be learned" and "competence," but not the definition of scientific literacy as functioning in society. All parallel structures in scientific literacy have accompanied the definition as functioning in society. And singular structure almost always appears in researches based on the views of scientific literacy in relatively recent times. Second, researches who have used "terms" as ways of representing scientific literacy have increased. Based on the results in this study, the meanings of scientific literacy have been emphasized in view of the ability of playing a role in a social context as well as learning and competence these days. To meet this movement in scientific literacy actively, science education community should get out of traditional teaching and learning scientific concepts and give emphasis on application in various context and social role of science learners.

The purpose of this study was to investigate how congruently the learning objectives of Earth Science I textbooks match the 2009 revised Earth Science curriculum. For this purpose, we classified the learning objectives of curriculum and textbooks were into three factors including ability, cross-cutting concepts, and behavioral verbs. The text data were analyzed using the semantic network analysis method. The results are as follows. The learning objectives of textbooks with regard to ability factors mainly emphasized the cognitive and affective domain. In addition, the ability of inquiry performance was emphasized in the learning objective of the curriculum. The textbooks used various sub-frame of cross-cutting concepts in comparison with the curriculum. Both textbooks and curriculum used the term 'comprehension' the most as behavioral verbs. However, most behavioral verbs just remained at the level of cognitive system.

In this study, we investigated the influences of students' motivational characteristics on the processes of learning density concept using a discrepant event. The participants were 642 seventh graders from two middle schools. Tests of failure tolerance, self-efficacy and mastery/performance goal orientation were administered as pretests. A preconception test was also administered. The intervention was the students' individual study of the density concept with a worksheet that was designed to incorporate the major steps of conceptual change learning. The tests of attention, effort and conceptual understanding were administered as post-tests. The responses of 203 students who had been found to possess the target misconception were analyzed. The results of a path analysis revealed that students' motivational characteristics variables did not influence cognitive conflict. Failure tolerance and mastery goal orientation, however, influenced conceptual understanding via situational interest, attention and effort. Self-efficacy influenced conceptual understanding via effort. Performance goal orientation negatively influenced conceptual understanding via attention and effort. Cognitive conflict influenced conceptual understanding directly as well as indirectly via situational interest.

The purpose of this study was to investigate secondary science teachers' PCK components and subcomponents that are specific to online and offline learning environment. Data collection consisted of survey, class observation, and individual interviews of twelve science teachers. This study used a theoretical framework of PCK for deductive data analysis and articulated codes and themes through the following inductive analysis. Data analysis revealed that each of PCK components showed different specificity to the online and offline learning environment. And subcomponents of each PCK component were different according to the specificity of the online and offline learning environment. Teaching orientation toward science had a specific orientation for the online learning environment, i.e., 'learning science concept' and 'lecture centered instruction.' Knowledge of the science curriculum had online-offline mixed learning environment specific knowledge, i.e., 'reorganization of curriculum' and online learning environment specific knowledge, i.e., 'development of learning goal' and 'science curricular materials.' Knowledge of science teaching strategies had online learning environment specific knowledge, i.e., 'topic-specific strategy', 'subject-specific strategy', and 'interaction strategy' and COVID-19 offline learning environment specific knowledge, i.e., 'topic-specific strategy' and 'interaction strategy'. Knowledge of student science understanding had online learning environment specific knowledge, i.e., 'student preconception', 'student learning difficulty', 'student motivation and interest', and 'student diversity' and COVID-19 offline learning environment specific knowledge, i.e., student learning difficulty'. Knowledge of science assessment had online-offline mixed learning environment specific knowledge and online learning environment specific knowledge, i.e., assessment contents and assessment methods for each.
