The purpose of this study was to analyze paper and pencil test items of life science I in high school to diagnose problems of the test items developed by teachers, and to provide some implication for better assessment. 690 selection-type items and 162 supply-type items in life science I were collected from 10 general high schools. In the analysis of test items, the ratio of the selection-type item and the supply-type item was 81:19 in the number of items based on item type, while the ratio was 74.4:25.6 in the distribution of marks, indicating that the distribution of marks compared to the number of items was higher in the supply-type items. In the analysis by the Bloom's revised taxonomy of educational objectives, the items of 'conceptual knowledge' in the knowledge and those of 'understanding' in the cognition process were shown most in both the selection-type item and the supply-type item. In the analysis by the science assessment frameworks of NAEA, the items of 'knowledge' were shown 9 times more than those of 'inquiry'. When compared to the level of difficulty presented in the two-way specification table and the percentage of correct answers in the selection-type item, the concurrence was 41.5%. When compared to the ratio of number of items based on the item type of the supply-type items, the short-answer items were 34.0%, the descriptive items were 61.1%, and the drawing items were 4.9%. The drawing items were mainly developed in the unit of 'Cells and Continuity of Life'. When the descriptive items were classified by the acceptance of response, all the items were 'response restricted' type, and the items of 'restricted in content range' type among them were highest. When the items were classified by presentation of data, the items of 'presentation of data' type were highest(65.4%), and when classified by type of question, the items of 'knowledge description' type were highest(80.4%). In conclusion, it is needed to develop items belonging to 'inquiry' area more in the school, and to increase the ratio of the descriptive items, presenting various types of items.

The period from 1946 until his retirement from Department of Forest Resources, Seoul National University was a time of research and professional activity on many fronts for Korean Plant Taxonomy. From 1952 to 1984, he travelled south Korea and collected more than 70,000 specimens. Working out of this project, Dr. Lee developed the SNUA herbarium (Herbarium of The Arboretum of Seoul National University) as the best University herbarium in Korea for the modem floristic work. Dr. Lee's first interest rests on his contributions to our understanding of the twig identification in early 1950. Asian deciduous oak taxa have attracted particular focus to him late 1950 and early 1960. Accordingly Dr. Lee has been one of the specialists on systematic study of Asian oak which is a basis of identification in eastern Asia now. Dr. Lee's contributions concerning rare and endangered plants in Korea provide a tremendous information after a Japanese taxonomist, T. Nakai did in early 1920 to late 1930 in Korea. During his fourteen year career from 1970 to 1984, Dr. Lee spent time to investigate flora of many local and National Park sites. Much of his effort was directed to the voucher specimens for which he worked for the Illustrated Flora of Korea and also served as a field collector. These collections at SNUA enabled us to extend our educational outreach from the local to the national flora research. Although Dr. Lee has been and continues to be the soul of SNUA, collection records about his purpose and aim for each trip are not well documented except date and field studied sites. This lesson enables us to tackle the same issue of balancing quantity and quality with well documented specimens now.

The purpose of this study is to examine science education researchers' views on what and how much science educational theories would be needed for pre-service science teachers, and to investigate the relationship between their views and the Examination for Appointing Secondary School Science Teachers(EASST). For this study, the views of science education professors on science education theories have been analyzed in terms of their priorities for contributing to the improvement of science teacher competency and literacy. Their views have been compared with proportions of questions related to science education theories of the EASST in terms of what kinds of science education theories have been used for solving each item. As results of this study show, they have perceived that more essential things are needed for the improvement of science teacher competency and literacy including science inquiry process, methods of experimental equipments and tools, laboratory safety, misconception of students, discussion, writing, evaluation of scientific knowledges, and evaluation of scientific inquiry ability other than science philosophy, changes of science curricula, science curricula of foreign countries, Bruner's instructional theory, Karplus's Learning Cycle model, generative learning model, discovery learning model, and Klopfer's taxonomy of educational objectives. There is a higher proportion of questions related to science curriculum and Ausubel's learning theory in the EASST. They are hardly correlated with science education professors' selections of science educational theories for EASST questions. This study advocates the needs of exploring a new method of narrowing down the gap between science educators' opinions and questions of ESSAT in terms of science educaiton theories.

The purpose of this research was to enhance the understanding of scientific thinking of $5^{th}$ graders of elementary school through conducting investigative analyses on the students' associations with regard to illustrations on science textbooks and to provide basic data that are needed for the teachers teaching science in classrooms to reorganize textbook illustrations suitable to the realities of science contents and realms. In order to achieve the research purposes, subject $5^{th}$ grade students were asked to write down what they associated with the illustrations on the matter part of the $5^{th}$ science textbooks of elementary school: among 14 illustrations, a half of them were after lessons and other half from before lessons. The types of students' learning goal statements according to Bloom's taxonomy of educational objectives were compared with the learning objectives provided in teachers' guide. The differences between before and after lessons in associated words which students used responding to given illustrations were investigated. Students' responses were analyzed in terms of how their associations were consistent with what their preference of learning objectives would be as well. Students variables including their achievement levels and gender were used as group variables in order to locate their effects on differences in their associations before and after the lessons. It was found that students manipulated the given illustrations more variously with more explanations before the lessons than after. After the lessons students tended to describe the illustrations more homogeneously and made theirs stick on the given direction by the textbooks. The implications for how school teaching affected to students' perception was made.

The purpose of this study was to compare the written tests of the science lessons at elementary schools with the instructional objectives of the teachers' guide for the first term of the 5th grade by using Klopfer's taxonomic system. In the analysis of the instructional objectives in the teachers' guide, A.0(40.0%) and $B.0{\sim}E.0$(42.4%) showed high level but the proportion of processes of F.0(5.6%), G.0(4.0%), H.0(4.0%), and I.0(4.0%) showed low level, while in the written tests A.0 was 54.8%, $B.0{\sim}E.0$ was 36.1%, F.0 was 7.3%, and G.0 was 1.8% but H.0 and 1.0 was not taken at all. In the comparison with the instructional objectives in the teachers' guide about the domain of the knowledge and the comprehension showed hish and the processes of the scientific inquiry showed relatively low. The results of this study suggested that a desirable written test should be made to consider elementary science curriculum and instructional objectives and hold up rates of each behavior category between the instructional objectives of teachers guide and assessment objectives of written tests.

The purpose of this study is to examine the effect of cooperative making problems and solving problems for formative assessment at finish stage on science academic achievement and scientific attitude. This study is conducted in 51 sixth-graders of two classes. The experimental group was provided with a teaching-learning course based on cooperative making problem and solving problem at finish stage. And the control group was provided with general classes based on the contents in teacher's guidebooks. The experiment was performed with the second and third units of the sixth grade, for about two month and obtained the following results: First, students prefer to make supply-type items than multiple choices. And by the Bloom's revised taxonomy of educational objectives, students prefer to make the problem types of 'Factual Knowledge' and 'Conceptual Knowledge'. Also students prefer to make the problem types of 'Understanding' and 'Applying'. Second, cooperative problem making and solving problems at finish stage has same effect on academic achievement in comparison to teacher-driven activity. Third, the experimental group made statistically significant difference in self-efficiency, contrary to the general science classes. Especially, it turned out that a meaningful effect was discovered to a cooperativity, openness. Finally, it turned out that many students thought cooperative making problem and solving problem at finish stage gave the help approving their cooperativity and openness at the investigation of awareness.

The purposes of this paper were to provide the basic segments of qualitative research to assist the understanding of qualitative research and to provide implications of indicators (i.e., criteria) to determine the rigor of the qualitative research in the area of Adapted Physical Education (APE). This paper was divided into five sub-categories to facilitate understanding the qualitative research, which were (a) the epistemological stances, (b) the data collection methods (c) the data analysis (d) the trustworthiness and (e) the implications of Adapted Physical Activity Taxonomy (APAT) in APE. Qualitative researchers deliver their understanding of human experience and knowledge by means of text rather than number so their explanations and understanding tend be subjective and distinct from otherwise interpretaotherwise (Crotty, 1998; Pitney& Parker, 2009). Examining the rigor of qualitative research is therefore concerned due to the complexity of understanding of reality (Goodwin 2020; Zitomer & Goodwin, 2014). In the meantime the roles of qualitative research have been highlighted in educational research including the area of APE because qualitative research enables researchers to examine different voices of school members (e.g., students with and without disabilities parents teachers Goodwin, 2020; Hodge et al., 2019; Zitomer & Goodwin, 2014).

This study has attempted to analyze the achievement standards in the 2015 revised curriculum, based on the revision of Bloom's Taxonomy and aims to identify the knowledge and required competencies in the fourth industrial era. The results of this study are as follows: First, the knowledge dimensions was the highest 'metacognitive knowledge' in middle school, while 'factual knowledge' was the highest in high school, and 'knowledge of specific details and elements' was the highest subtype of all of the knowledge dimensions. The dimensions of the cognitive process, such as the terms 'apply' and 'analyze' in middle school, as 'understand' and 'evaluate' in high school have been treated inattentively. Second, the knowledge dimension and the cognitive process dimension according to key concepts display the metacognitive knowledge and 'understand' in development, the conceptual knowledge and 'understand' in relationship. While the 'metacognitive knowledge' and 'apply' in life culture, the 'procedural knowledge' and 'evaluate' in safety, the 'factual knowledge' and 'apply' in management and the 'metacognitive knowledge' and 'understand' in life design were extremely high. Third, the verbs used in the achievement standards displayed as 'explore', 'understand', 'analyze', 'practice', 'suggest', 'recognize' and 'evaluate'. Since the statement of the action verb is the very basis for determining the performance process, specific competencies may be achieved by reflecting on the actual achievement standards. These standards should provide us with a effective cognitive process for to understand a learner's performance skills and support the direction of the education required, through a strategy that refines the connection between content elements and functions and develop their competences for the future.

This study is to make suggestion for developing textbook systematically by analyzing biological contents and organization in science textbooks which are important instructional media to accomplish objectives of the 6th middle school science curriculum. The inclusiveness degree of the 6th science educational objectives reflected in the textbooks was analyzed by Klopfer's and the Korean Educational Department's objectives taxonomy. And the biological contents and the organization of the science textbook were analyzed by learner, subject matter, and society dimensions which are selecting criteria for curriculum objectives suggested in Tyler's curriculum model. The analyzed results are as follows: 1. The inclusiveness degree of the educational objectives was very low. 2. Regarding the dimension of learner, the concepts of formal operational cognitive level were much increased as grade becomes higher. And the degree of learner's interests reflected on the learning topics and domains was very low. 3. Regarding the dimension of subject matter, the concept-centered learning was increased, in relation to inquiry learning as grade becomes higher. The analyzed results of inquiry subskills showed that observation, classification, and recording skills in 1st grade, observation and operation skills in 2nd grade, and interpreting data skills in 3rd grade were centered. As the problems and processes were presented, so most of inquiry activities had low openness scale. The learning contexts were organized into discipline-centered in relation to real life. 4. Regarding society dimension, the learning topics of environments and health were much presented. but those of biotechnology and career were presented scarcely. And most learning topics related society dimension were organized in textbooks of the 2nd and 3rd grade. These suggested that to accomplish curriculum objectives effectively. the inclusiveness degree of educational objectives is to increase and, the contents and organization of textbook were constructed harmoniously in aspects of learner, subject matter and society dimensions.

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.
