  • Unlike Korean science curriculum's continued push for "relevance of contents" to reduce the burden of learning on students, IB DP (International Baccalaureate Diploma Programme) is chosen in many countries and the number of IB world schools continues to grow, although it contains not only a large amount of learning but a substantial amount of content that requires quantitative calculations. Through this study, we suggest implications for Korean science curriculum and textbook, by comparing the constructions of chapters, the achievement standards, the learning contents, and the formulas of physics textbook, focusing on the 'relativity' unit of the 2015 revised national curriculum and IB DP, and by analyzing the questions of college scholastic ability test (CSAT) and external assessment (EA).

  • Recently, the use of one-person broadcast content for special makeup videos has gained momentum. This study aims to analyze the factors preferred by various age groups as the total number of clicks increase on special makeup videos. It also aims to provide beauty creators with useful data to help them create videos that generate more clicks based on the derived elements. We analyzed previous studies and divided the subjective indicators into place & accessories, editing, model (Y/N), contents and field, and characteristics of the creators. We analyzed top 5 videos from among 257 videos uploaded before July 1, 2020. The subjective indicators were analyzed through a questionnaire survey attempted by 60 respondents in their 10-30s from Jeollanam-do and Gwangju between July 20 to August 31, 2020. The questions majorly focused on intimacy, attractiveness, professionalism, informativity, and playfulness. We analyzed the collected data using SPSS 21.0, and obtained the following results: Informativity, professionalism, attractiveness, and playfulness were considered to be more influential by those aged 10 to 30 years. In particular, factors like visual elements, linguistic characteristics, experts, background music and sound effects, celebrities, product information, and knowhow were most preferred. In fact, it was easy to make videos using these elements. The above results confirmed the utility of such data for beauty-creators-to-be in creating videos that generate more clicks.

An Exploration of Discrepancies between Text and Content Knowledge of Pre-service Elementary Teachers through an Analysis of Questions and Answers Created in the Interactive Reading of a Teacher's Guide: Focusing on a 'Shadow and Mirror' Unit (상호작용적 독해 과정에서 생성된 질문과 답변의 분석을 통한 교사용 지도서와 초등예비교사의 내용지식 사이의 불일치 탐색 -'그림자와 거울' 단원을 중심으로)

  • This study explored the discrepancy between the text of a teacher's guide about straight and reflective light and the content knowledge of pre-service elementary teachers. A total of 455 questions and 543 answers generated by 279 pre-service elementary teachers after reading a 'Shadow and Mirror' unit in the teacher's guide were analyzed. The questions were classified according to the types of concepts and discrepancies, and the answers were analyzed for accuracy. The results of analyzing the concepts of questions revealed that the pre-service elementary teachers were most curious about the shadow in the straight concept, the mirror image in the reflection concept, and the light source in other concepts. The questions with a low correct answer rate due to incorrect- or non-answers, such as those concerning the superposition principle of light by reflection, the principle of experimental tools, and images by lenses, were only partially or not included in the teacher's guide. When the questions were classified according to the type of discrepancy, the frequency of questions due to knowledge deficit was higher than that due to knowledge clash. This demonstrates that the concepts that teachers need to know must be supplemented with the contents of the teacher's guide. Discrepancies due to knowledge clashes are often caused by conflicts between what is experienced in everyday life and what is presented in textbooks. Therefore, it is necessary to reduce the discrepancy between the texts of the teacher's guide and the knowledge of pre-service elementary teachers by including the differences between the actual context of everyday life and the context of the textbook in the teacher's guide.

  • The purpose of this study is to analyze and evaluate the Cyber Home Learning contents of Earth science area in the basic course of the $10^{th}$ grade. For this purpose, we applied the 'Cyber Home Study Content Quality Control Tool' presented in Elementary Secondary Education e-Learning Quality Management Guidelines (Ver.2.0)' of Korea Education & Research Information Service(2008). The results of Cyber home learning contents analysis are as follow: First, it was presented that the study guide introduced the contents which should be studied for one class, properly. And it was not analyzed that the diagnosis assesment was not completed in the initiative study; Second, it was possible to study choosing the contents fitting the learner's level of learning in the main study, it was comprised of about 10 minutes. Third, it was performed without feedback for incorrect answers in the learning assessment, just the number of wrong questions. And the learning arrangement present the important contents learned in that class, summarizing and arranging again. The results of evaluating the contents in Cyber Home Learning are as follows: First, in evaluation section of instructional design, many text materials which were so difficult for learners to read were explained, being provided. Besides, the systematic structures leaves much to be desired, in view of learners' learning experience, contents, and environment. And in evaluation section of learning contents, the error of contents caused the learning contents not to appear, the amount of learning in each section was found too much. Second, in evaluation section of the strategy for Teaching and Learning, when we mention the strategy of Self Directed Learning, the environment to make learners search for information free and self-study possible was not possessed well. And in evaluation section of interaction, it was found that a simple click caused the learning to go on. Third, in evaluation section of evaluating, it was evaluated that there was wanting in consistency in learning aims, contents, evaluation contents.

  • This paper presents a case study to develop e-learning contents of agricultural safety based on the assessment of risks of 4 selected crops and stock farming: rice, potatoes, apples, tomatoes and stock raising. The aged farmers, who are main workforce of current Korean agriculture and relatively more vulnerable to various risks of agricultural work compared to younger workers, were considered as the main users of the contents in developing them. The safety guidelines were presented as simple as possible and the interfaces were designed to be simple and easy to use so that the older users can use it without much difficulty. In making the scenarios of the contents, risk assessments were carried out for each crop and stock farming with the focus being on occupational diseases rather than accidental injuries. To make the contents more attractive to the farmers, the functions requiring active responses from the users, such as answering simple questions, were included in the contents. Usability evaluation by experts of ergonomics and agricultural tasks were carried out in modifying the draft version, whereas formal usability test was not included in the case study. Though there are some limitations in the developed contents in the aspects of evaluation of usability and effectiveness, this case study shows the structured procedure of developing e-learning safety contents based on the risk assessments on agricultural tasks. The developed e-learning contents are expected to be used practically and easily in educating and training older farmers about safety and health of agricultural tasks.

  • The purpose of this study is to investigate the aspects of verbal interactions of teacher?small group students by categorizing those interactions which affect students' thinking thus to improve teacher's interaction. First, verbal interactions of teacher-small group students were divided into two categories ?Behaviors related to problem-solving, and Others. Behaviors related to problem-solving were also classified into two elements?Receiving opinion based on the students' thinking process, and Giving help based on the teacher's thinking process. Receiving opinion consists of agreement, question, correction, objection while giving help consists of information, hint, question, summary, and ask & answer. Most of teacher-small group students' interactions were in the form of teacher's questions and students' answers, and teacher's questions tended to require simple answers rather than answers from deep thought. In addition, there was a tendency that the teacher focused more on her own thinking process than students' and that she interacted with only a couple of students who gave correct answers. As a result, even after teacher's scaffolding, many students were often unable to understand the particular contents. However, through the interactions, the teacher made students to have confidence by restating their opinions and agreeing or praising them. She also created an atmosphere where students can give their opinions freely. From the observation of interactions, we can find that students' thinking process is affected by the characteristics of teacher's interactions such as expression of agreement and encouragement, hint giving rise to thought, interactions based on the students' thinking process, permission of students' activities and questions, allowing time for students' thought, and correction of wrong opinions. At this point, educational implications of teacher-small group students' interactions were drawn.

  • This study was made for male and female university students regarding the nutrition knowledge about fat, fat contents in food, and practice toward fat. The result is as follows;1.Out of 13 questions inquiring the knowledge about fat a significant difference was observed between female and male students in 10 questions. Male students' nutrition knowledge about fat was $6.33{\pm}0.16$, and that of female students' was $6.33{\pm}0.16$ and there was no significant difference. The ratio of correct answer was 49% and 59% respectively. Female students marked high ratio of correct answer such items as ${\omega}-3$ fatty acid, the relation between high fat diet and atherosclerosis(coronary disease), the relation between obesity and fat, the relation between ${\omega}-3$ fatty acid and heart disease, cholesterol, fatty acid in butter, degree of unsaturation in liquid oil, margarine, chicken fat, rancity of fat. 2.Male students' total score of knowledge about fat quantity in food was $4.91{\pm}0.10$ and that of female students was $5.58{\pm}0.10$. There was significant difference(p<0.001) and the ratio of correct answer was 55% and 62% respectively. Out of 9 food items, significant difference was observed in 7 items according to student's majoring subject. The ratio of correct answer for the questions about the quantity of fat in food female showed high figures in such items as white meat(p<0.01), whole milk(p<0.0001), skim milk(p<0.01), potato chips(p<0.001), biscuit(p<0.001). However, male students showed high figures on the question about the quantity of fat in vegetable margarine. 3. Out of 12 items observing the degree of diet practice on fat, significant difference was observed between male and female students in 6 items. Female students practice the question items positively with high ratio: intake of fish instead of meat(p<0.01), removing visible fat in meat(p<0.0001), removing chicken skin(p<0.0001), removing oil during cooking (p<0.05), selection of low fat milk or skim milk(p<0.05), selection of meat part(p<0.001). There was significant difference between male and female students in practicing diet on fat (p<0.001) and the total score was $31.52{\pm}0.52$ and $34.65{\pm}0.41$ respectively.

  • This study aims to analyze the characteristics of reflective thoughts of students during experiments in general physics experiments. The participants were 32 college students, they submitted 10 experiment reports including answers to questions for reflective thinking. The results were as follows: First, students show reflective thinking broadly in the experiment, levels were followed by practical reflection, technical reflection, and critical reflection. Also, they actively accepted the knowledge related to experiments, but were passive in connecting new knowledge and experiences obtained through the experiments or forming new questions. Second, the reflective thinking of students show high correlation with experiments related to prior knowledge or the easy-to-understand process. Third, through the qualitative analysis of open-ended questions, it was confirmed that technical reflection occurs in individual evaluation, practical reflection in group evaluation, and practical reflection and critical reflection in improvement proposal. While the students' reflective thinking were superficial or mainly functional, however, they recursively examined the learning contents and the experimental process concurrently.
