  • The purpose of the current study was to investigate the effects of explanations about physical phenomena given in non-physics textbooks on the formation of student physical conceptions. Two classes, 39 students in each, were sampled from two middle schools in Pusan, Korea, and two kinds of test tools for investigating student conceptions were developed for the study. The first test tool(a) investigated student conceptions after reading explanations about physical phenomena in non-physics textbooks, while the second(b) investigated student conceptions after reading explanations revised by physics education experts about the same physical phenomena. The two test tools were applied to each class, and for a fair invetigation, test(a) followed by test(b) was applied to one class, while test(b) followed by test(a) was applied to the other class. The results were as follows: In both classes, the students' level of understanding from explanations revised by physics education experts was significantly (p < .01) higher than that from explanations in non-physics textbooks. As such, it is feasible that false or inappropriate explanations in non-physics textbooks can cause student misconceptions. Moreover, the improper expression of physical science concepts, improper choice of scientific terms, and incorrect grammatical structures, along with the use of unsuitable examples and improper model pictures can make it difficult for students to understand physics concepts. Furthermore, differences in the terms used in physics textbook and those used in other textbooks can also confuse students' learning.

  • In 21st century, it is essential to understand Nature of Science (NOS) related to science educational curriculum. The study analyzed Earth Science components of third- through sixth-grade science textbooks in terms of incorporated NOS themes and their relative proportions. Modified analysis methods of Chiappetta et al. (1991) and Lee (2012) are devised and adapted. The results of analysis indicates that the current elementary school textbooks include and explain all the four themes of NOS, but do not include sub-areas of each theme of NOS in a balanced way. In addition, the themes of NOS in Earth Science are not treated equally among different grades. Such results warrant the efforts to include balanced themes of NOS into elementary school science textbooks with the ultimate goal of fully and properly comprehending NOS to the students.

  • In this study, we analyzed the end-of-chapter questions in 8 types of chemistry II textbooks for science teachers according to revised Bloom's taxonomy of educational objectives not only to raise interests of questions in textbooks but also acquire a basic material for using questions in textbooks effectively. The results of classification following Bloom's cognitive category showed that 'Understanding(44.7%)' level was the most, then 'Application(29.9%)', Knowledge(15.6%) and 'Analysis (9.5%)' in order, which is distinct difference from the result of classification of the end-of-chapter questions in college general chemistry books which was 'Application', 'Analysis' and 'Understanding' in order. Especially, questions of 'Evaluation' level were not found at all in any textbook investigated and 'Synthesis(0.3%)' level was very few. On the other hand, the percentage of questions in 'Understanding' and 'Executing Quantitative' which required specific algorithms was 70% of total with most of the questions in 'Application' were 'Executing Quantitative'.

  • Based on the current curriculum, students learn the concept of fraction in the 3rd grade for the first time. At that time, fraction is introduced as whole-part relationship. But as the idea of fraction expands to improper fraction and so on, fraction as measurement would be naturally appeared. In that situation where fraction as whole-part relationship and fraction as measurement are dealt together, it is necessary for students to get experiences of understanding and exploring unit and whole adequately in order to fully understand the concept of fractions. Therefore, the purpose of this study is to analyze how to deal with unit fractions, how to implement activities to find the standard of reference from the part, and what visual representations were used to help students to understand the concept of fractions in elementary mathematics textbooks from the 7th to the 2015 revised curriculum. And we analyzed 60 3rd graders' understanding of finding and drawing the whole by looking at the part. Several didactical implications for teaching the concept of fractions were derived from the discussion according to the analysis results.

  • This study investigated and analyzed the social and emotional learning components of middle school science, and high school integrated science and science inquiry experiments, which are common subjects that all students must complete. The subjects of analysis were 139 achievement standards of science and curriculum and 496 activities included in textbooks. The research results are as follows. In the case of curriculum achievement standards, 'cultural understanding' was hardly included among the seven science and social-emotional learning elements, 'numeracy' and 'creative thinking' appeared high in middle school, 'critical thinking', 'social technology' and 'ethical understanding' were included with high frequency in high school. And in the case of textbook activity, the tendency of social-emotional learning elements in middle school and high school was similar. 'critical thinking', 'creative thinking', and 'social skills' were mainly provided, while 'ethical understanding' and 'cultural understanding' were reflected in a limited way. In order to cultivate the elements of overall social-emotional learning, it is necessary to specify the achievement standards of the curriculum or to supplement the textbook activities and teaching-learning process.

  • This study analyzed the introduction of addition and subtraction, including the composition and decomposition of numbers in the Korean, Singaporean, American, and Japanese elementary mathematics textbooks. The analytic foci of this study included visual models and their connections with the given problem contexts, the introduction of addition/subtraction or addition/subtraction sentences and their connections with the visual models, and additional activities for students to develop a relational understanding of the equal sign. The results of the analysis demonstrated diverse connections, mainly because the problem contexts, visual models, and the introduction of addition/subtraction or addition/subtraction sentences were implemented differently for each textbook. There were differences among the textbooks in what order of problem contexts were presented. Regarding the use of visual models, two textbooks tended to use one model consistently, whereas the other textbooks used various models depending on the problem contexts. There were subtle but significant differences in introducing addition/subtraction or addition/subtraction sentences. For a relational understanding of the equal sign, all textbooks included activities emphasizing that both sides of the equal sign are equal. Based on the results of this study, this paper closes with several implications related to the problem contexts to introduce addition/subtraction and addition/subtraction sentences as well as the use of visual models, which can serve as a basis for a new unit for the subsequent textbook.

  • This study analyzed high school informatics textbooks that were developed based on the 2015 Revised National Curriculum. Content analysis was adopted to analyze the organization system of the textbooks. Learning objectives were also analyzed according to Anderson's taxonomy of educational objectives. Through content analysis, it was revealed that the textbooks were composed of activities, differentiated learning, and small group learning to promote core competencies. The analysis of learning objectives of the textbooks showed that 'understanding' (41%), 'developing' (20%), and 'applying' (18%) were the three highest criteria in terms of cognitive processes; in terms of type of knowledge, conceptual knowledge accounts for the highest(45%), followed by procedural (32%), and factual (12%). Further methods to improve the textbook quality is proposed based on the results from this analysis.
