As one of the serial faunistic studies on the brackish cyclopoids from Korea, taxonomic accounts of three species of Halicyclops from various brackish waters in South Korea are provided, with detailed illustrations of them: H. uncus Ueda and Nagai, 2009, H. setiformis Ueda and Nagai, 2012, and H. itohi Ueda and Nagai, 2012. Halicyclops uncus is newly recorded from Korea, and the latter two species are corrected from H. sinensis sensu Chang, 2009 and H. cf. rotundipes sensu Chang, 2009, respectively. As a result, a total of seven species of the genus are now recognized in Korea, and a revised key to the species is presented.

This study investigated students' alternative conceptions of plate boundaries and their conception revision according to the pattern of students' reasoning. Participants were twenty-two 10th grade high school students. All participants were asked to draw the three types of plate boundaries and to explain their drawings. Nine students participated in the reasoning activity. To this end, a semi-structured interview was conducted during which key questions were asked for the students to individually answer. The key questions used in the reasoning activity were created, by utilizing questions used in the previous studies. The findings revealed that the alternative conceptions of plate boundaries were classified into three levels based on established criteria. Students who attempted a variety of reasoning strategies such as causal reasoning, using an analogy, abductive reasoning, data reconstruction and concept combination, revised their alternative conception to a scientific conception after the reasoning activity. On the other hand, some students could not revise their alternative conceptions because they only conducted an incomplete reasoning strategy. The study also found that they were unable to use other reasoning strategies, either.

A new species of gudgeon, Microphysogobio rapidus is described from 25 specimens collected from the Naktong River system, Korea. The new species is similar to Microphysogobio yaluensis but is distinguished from the latter and congeners by the combination of the following characteristics: number of papilla on the upper lip, 4.5 scales above the lateral line, short distance from the anus to the origin of the anal fin, wide scaleless area of the abdomen, nuptial colour consisting of a longitudinal green stripe on the lateral side of the body and bright blue colour of the suborbital region and operculum. A key to the species of Microphysogobio from Korea is also included.

The first zoeas of Chinese ditch prawn Palaemon gravieri (Yu, 1930) and carpenter shrimp Palaemon serrifer (Stimpson, 1860) are described and illustrated in detail based on laboratory-hatched material. They are distinguished from those of Palaemon ortmanni (Rathbun, 1902) and Palaemon pacificus (Stimpson, 1860), previously known larvae from Korean waters by the length of the rostrum and endopod of antenna, the shape of the third abdominal somite, and ornamentation of the fifth abdominal somite. Larval characters of the genus Palaemon are revised. A. provisional key to the known first zoeas of Palaemon from Korean waters is given.

The purpose of this paper was to analyze the kinds and roles of multimedia materials in E-works that are distributed with elementary textbooks (3~6 grade) of the 2009 revised science curriculum. Five criteria (forms, goals, key competencies, inquiry process, running time) were set for this. The sample of the paper was the 784 multimedia materials in E-works of elementary science textbooks (3~6 grade) of the 2009 revised science curriculum. The results of the multimedia materials analysis are as follows: The result of the material forms of multimedia is that the form of highest ratio is text type. But all forms were used evenly in E-work. 56.2% of the multimedia materials are for "inquiry" in the goal criteria, and 65.0% of the multimedia materials are related to "science inquiry" in the key competencies criteria. Two facts indicate many multimedia is used to develop students' inquiry ability. However the ratio of multimedia materials in motivation step is higher than that in inquiry activity step. In analysis of running time, the ratio of "under 5 min" multimedia materials is the highest. But, the ratio of 5~10 min multimedia materials in inquiry part is higher than that in motivation part in The Chi-square test between "running time" and "parts" that consist of motivation part and inquiry part. Through the analysis of module and the categorizing the multimedia materials, we found that the multimedia materials play eleven roles in E-works that are distributed with elementary textbooks.

Objectives: This study aimed to develop dietary education textbooks for elementary school students by focusing on the three core values of environment, health and gratitude from the National Food Education Plan. Methods: The contents of textbooks and teacher's guidebooks were developed with brainstorming of the authors as well as consultation with experts and by considering not only the three core values of environment, health, and gratitude, but also the performance indicators of the 2nd National Food Education Plan and the key competencies and creative convergence approach of the 2015 revised national curriculum. Results: A total of 12 different dietary education textbooks named 'Good Dietary Life Guide' and the teachers' guidebooks from the first to the sixth grade of elementary school were developed. The textbooks were fundamentally developed connecting the three core values, the outcome indices of the 2nd National Food Education Plan and the key competences of the 2015 revised national curriculum. Various educational activities such as thinking, debate, writing, cooperative learning, experience, practice were included to promote students' participation. These books could be utilized in every field of dietary education targeting elementary students such as creative experiential activity, convergent classes (integrated subjects, Practical arts, Social studies, Science, Moral education and Korean), after school classes, rural experience, general agricultural education, after-school child care services and community child care centers. Conclusions: The continuous and repetitive use of the textbooks from the first to the sixth grade would contribute to the improvement of food habits and the personalities of elementary school students, and consequently make the students grow up as healthy citizens.

This study intends to suggest implications by comparing the high school mathematics curricula between Korea and the UK ahead of the 2022 revision of the mathematics curriculum. The UK has revised assessments to emphasize mathematics after age 16 since 2017. Thus, in this study, the contents of Key Stage 4, Core Maths and A-level, which correspond to the UK high school mathematics curriculum, were examined and compared with Korean high school math subjects. In the UK, mathematics education is more emphasized at the high school level. The national curriculum emphasized 'numeracy and mathematics', and students' selection for mathematics courses were expanded. In order to prepare for the future society, new mathematics subjects and evaluations were developed and implemented, and the A-level mathematics was improved. In addition, the subject-centered content was developed and continuously handled from Key Stage 3 to the high school stage. It was structured to facilitate mathematics' internal and external connection by linking it with the subjects of other areas.
