  • The purpose of this study is to compare inquiry activities in science textbooks' physics contents for Korean secondary schools with those of Singapore in order to provide a reference for further improvement of inquiry activities in Korean science textbooks. We analyzed inquiry activities using the framework of Millar et al.(1998) and Chinn & Malhotra (2002). The results of this study are as follows: There are differences between Korean and Singaporean inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness'. In the area of 'learning objectives', the Korean textbooks have more activities associated with the learning of science content than those in Singaporean, whereas the Singaporean textbooks have more activities associated with the processes of scientific inquiry than in Korean textbooks. In the area of 'students' thinking activities', the Singaporean textbooks have activities like 'test a prediction', which Korean textbooks lack. The 'degree of openness' is higher in Singaporean textbooks than in Korean textbooks. And some differences in the area of 'authentic scientific inquiry' between Korean and Singaporean textbooks were also found. While the Korean textbooks do not have any activities associated with 'generating research questions', the Singaporean ones feature such activities. In the area of 'designing studies', the Singaporean textbooks have activities corresponding to 'selecting variables' and 'controlling variables', while the Korean ones never have such activities. The results of this study imply that it is necessary to balance inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness', and to present activities close to authentic scientific inquiry in inquiry activities in textbooks.

  • To accommodate today's higher education student, fewer textbooks are printed and more are becoming digital. Keeping with the modern era, hybrid versions of textbooks have all end-of-chapter assessment content moved to digital learning systems such as MindTap$^{TM}$ by Cengage $Learning^{(R)}$. In this work, we introduce new pedagogical strategies to combat academic e-cheating, specifically cheating on assessments given in online astronomy courses. The strategies we present in this work are employed in Horizons: Exploring the Universe, Hybrid, 13th Edition, and Universe, Hybrid, 8th Edition, by Seeds, Backman, and Montgomery.

  • Language skills in science education seem to have a great impact on student achievement. Most of the language skills affecting students' science learning can be accounted for an understanding of scientific terms. The ultimate goal of this study is selecting and grading the scientific terms for science education. As a basic research, we investigated scientific terms contained in science textbooks, because they are the most basic and selected terminologies. As a result of investigation of scientific terms in physics units of middle school science textbooks, we made a list of 556 scientific terms by grade level. This includes 249 words for grade 7, 170 words for grade 8, and 137 words for grade 9.

  • In this study, the contents of 'electric current' and 'battery' units in elementary and middle school science textbooks were analyzed on the basis of particle and energy concepts. Many problems, reported previously on students' misconceptions about those area, were found in science textbooks. Electric current and battery were covered in both physics and chemistry parts of science textbooks. However, the lack of particle concept in physics units and the lack of energy concept in chemistry units seemed to make it difficult for students to learn those concepts. The descriptions about the two concepts were also not consistent even in the same discipline units. In order to solve these problems, the integration of the views on the particulate nature of matter and energy in the science curriculum and reconstruction of science textbooks were needed.

  • Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.

  • This study investigated science textbooks used from 1906 to 1915 in Korea, which is often neglected in previous researches. By doing so, more practical and specific understanding of the science education during that period can be made. It was based on the historical achieves "School Textbook List"(Vol. $4{\sim}9$) which was published by the Ministry of Education and the Government General of Chosen and other sources. The results and conclusions of the research are as follow; (1) The science textbooks which have been used from 1906 to 1915 in Korea can be categorized into three different tapes of books, either written in Chinese, or in Japanese, or in Korean. The names of science textbooks were Nature Study, Physics, Chemistry, Natural History, Hygienics, Physiology, Zoology, Botany, Astronomy, Physiography, Mineralogy, Geology. These names were much broader than those in curriculum settled by the government and rather correspond to the names of science textbooks in curriculum which settled by private schools. Therefore those science textbooks had been mainly used in private schools. Moreover almost all of the science textbooks published in Korea have started to appear after 1906. Since then many schools were newly opened and the number of students increased. It is possible to say that substantial science education in Korea established after 1906. (2) Science textbooks from 1906 to 1915 printed in Korea were controlled in their use by the Ministry of Education and the Government General of Chosen. They were the main means of government regulations, supported by Private School Ordinance, Regulations for Official Examination of textbooks in 1908 and Law of Publication in 1909. According to the result of official examination, as the time went by under the Japanese ruling of Korea, the increasing number of science textbooks were getting banned. While the science textbooks had enjoyed more freedom than the other textbooks from the control by inspection of the Government General of Chosen, the situation has been significantly changed as Japan started to intensity the control of all kinds of textbooks in Korea. Although there were a lot of copied science textbooks, 62 science textbooks printed in Korea, 72 Japanese science textbooks were used in Korea, and 40 Korean were to be engaged in science education compiling and copying science textbooks. There developments in science textbooks alone suggest that there were enormous amount of potentials in Korean science education at that time. However, all of these effects and progresses were destroyed when the sovereign authority of Korea was lost to Japan in 1910.

  • The aims of this research are to analyze the representations and conceptual sequence of eye vision in Korean science textbooks and to suggest a contents construct about eye vision where the conceptual sequence is considered. Research method was literature review, and the literatures that were used for analysis were the 7th Korean science curriculum which was revised in 1997, and the science and physics textbooks developed based on the 7th Korean science curriculum. The research results are as follows: 1) Although the science curriculum seems to have no problem on sequence in the eye vision concepts, the science and physics textbooks based on the curriculum reveal problems on the sequence in the eye vision concepts; 2) Some Korean science textbooks explain retinal image formation according to the Alhazen's idea, except in inverse image; 3) Some Korean science textbooks explain about the reasons of near- and far-sightedness without consistency between the textbooks for 7th and 8th grade students; 4) A few Korean science textbooks give an inappropriate explanation about the principle of eye sight correction by eye glasses; 5) According to the analysis result, the concepts related to eye vision should be presented in the order of explanation about light refraction phenomena, image formation process by convex lens, structure of human eye and retinal image formation process, correction of eye sight using lens.

  • In this study, we identified the conceptions of heat and temperature on a basis of the science history, and analyzed the explanation types in elementary, and secondary school science textbooks. From these data, we tried to discover the cause of students' misconceptions. The results revealed that the explanation types of the textbooks don't include modem sight. Different conceptions developed in different era mixed in the textbooks. We can infer that students who learn heat and temperature concept by the textbooks could have misconceptions because of the above problems.
