In this paper, we examine the different viewpoints of teachers and undergraduates on middle school informatics textbook. For this research, a survey is conducted on middle school informatics teachers and undergraduates who are preparing the state examination for informatics-computer teachers. Items of the survey were chosen to investigate the level of completion on the contents and structure of the textbook and to examine overall satisfaction with the textbook. Seven items concerning the level of completion are based on national textbook authorization criteria. A t-test was performed to analyze meaningful difference in perception of textbook between the teacher and student groups. The result shows there is meaningful difference on two items which are 'compliance with informatics curriculum' and 'content selection and organization'.

The purpose of this study is to analyze illustrations, contents, and experiments in 6 kinds of science textbook from the 9th grade covering the phases of the Moon (on the phases of the Moon in six 9th grade science textbook) and to suggest coherent and effective contents and frame of the science textbook. Hence, the researcher decided the study problem. The study problems are as follows; 'Are the illustrations in the science textbook presented to help understand the phases of the Moon depending on the position of the observer?', 'Does the contents of the book clearly mention the phases of the Moon?', 'Can students understand the phases of the Moon through the experiments in the science textbook?', 'Do illustrations, contents, and experiment of the science textbook consistently explain the phases of the Moon?'. 10 persons (9graduate students including the researcher) took part in this study. All things unanimously agreed upon by all participants were reflected in the results. The results are as follows: First, the universal observer's view point is mixed with the earth observer's view in the illustration of these science textbook regarding the phases of the Moon. Moreover, illustrations of some textbooks are presented with such words as 'sunrise', 'midnight' and consequently contain too much. Second, the contents of the science textbook concerning the phases of the Moon is not described clearly. In addition, they don't give clear and detailed explanations for the reason of these changes. Third, all of the textbooks, except one textbook, describe the experiment regarding the phases of the Moon with the earth observer's view point but don't specifically mention that the view point is that of the earth observer's view point. Fourth, illustrations, contents, and experiments in the science textbook don't coherently explain the phases of the Moon. In addition, it is confirmed through the process of the result analysis that the described contents in the science curriculum is not well constructed or logical.

Analyzing textbook is the first step for enhancing the level of biology education especially in Korea. Prior studies of textbook analysis have mostly dealt with such topics as terminology analysis, content analysis, relationship analysis of chapters, and comparative studies. However, not much attention was paid to concept system to be learned and to relevance of concepts chosen. Therefore, the purpose of this study is to clarify the concept system and to elucidate the relationship among concepts for effective learning. Novak's concept map was utilized as a theoretical framework for the analysis of chapter I of high school biology textbook. Concept map has several distinctive merits in many aspects such as teaching, learning, and evaluation. It not only makes the understanding of key concepts and proposition a lot easier, but also helps to link prior knowledge and new concepts more effectively. This study will be a basic material for improving textbook for effective biology learning. The conclusions of the study are as follows: 1. Concepts in subchapters were arranged unsystematically or they were overlapping. For more effective understanding, those items should be rearranged. 2. Key concepts are not arrayed properly according to their hierarchy. Therefore, it was hard for students to set up concept structure. 3. The concepts emphasized by bold letters were not selected properly in accordance with their importance. Appropriate concepts should be chosen. 4. Key concepts should be explained by using examples in everyday life for easy understanding. 5. Many concepts in molecular biology is too abstract to grasp their meaning. Therefore, many audio-visual materials should be used to aid concept building.
