In the era of the fourth industrial revolution, maker education is drawing attention as a method of student-led education. At a time when interest in maker education is also growing in technology education, figuring out what stage of concern(SoC) a middle school technology teacher is critical to effective implementation. This study analyzed SoC in maker education by layer sampling among 400 middle school technology teachers using Concerns-based adoption model. SoC was then obtained by measuring the origin using the SoCQ and then presenting it as a SOCQ profile. Gender, training experience with two lower variables were analyzed using t verification, working cities, teaching experience with more than three lower variables were analyzed using one-way ANOVA. Studies showed that SoC in maker education of middle school technology teachers showed the most similar characteristics to that of non-users. The difference in concern depending on gender was that male teachers were more concerned in maker education than female teachers. The difference in concern depending on the working city was that teachers working in the township were more concerned in the maker education than teachers working in the large city, and the difference in concern depending on the teaching career was higher among teachers with middle experience than those with low and high experience. There was also a higher stage of concern in maker education than in teachers without training experience. Therefore, it is necessary to provide middle school technology teachers with an introduction to the maker education and various information, teaching, learning and evaluation data to enhance overall concern and to support the use and evaluation of the maker education in the classroom by providing various teacher training and consulting on the maker education in the future. Further, through further study, we should conduct study that analyzes both Stage of Concern, Level of Use and Innovation Configuration, to put in the effort for effective settlement of maker education.

There have been much efforts to reconstruct the science curriculum focusing on Disciplinary Core Ideas(DCI) in many countries such as America and Europe, the most practical effort has been to design a curriculum with learning progressions(LPs). LPs describe stepwise how students can systematically move toward the understanding of more sophisticated ideas or scientific activities and explain in succession the process of understanding the ideas while the students learn. In this study, a LP for ecosystems has been developed, and the developed LP is then evaluated accordingly. The Ecosystem is one of the DCI of the life science in Next Generation Science Standards(NGSS). The development process of the LP was set at step 4(Development, Assessment, Analysis, and Amendment), and developed through an iterative process of sequences. As a result of analyzing the developed LP, an assessment based on the LP provides reliable information to identifying student ability. This study proposes the development process of the LP and its methodological aspects to use Core Achievement Standards, Ordered Multiple-Choice items and the Rasch model. In addition, using the empirically proven LP suggests a way of strengthening curriculum linked to educational content, teaching methods and assessment. Utilizing the proposed development process in this study will be to present the standard into the direction of becoming part of the curriculum. Currently, the state of domestic research for the LP is still lacking. This study determined the development process of the LP and the need to conduct future research on the LPs.

In order to help elementary students understand the astronomical unit in depth, this study applied backward design 2.0 to check the effect on students' science academic achievement, performance evaluation, and science class satisfaction. As a result of the study, there was no statistically significant difference in the science achievement test, but the average score of the experimental group has improved. As a result of the performance evaluation test, there was a statistically significant difference because the feedback was well provided through the process-focused assessment and it helped in-depth understanding. As a result of the science class satisfaction test, there was a statistically significant difference in the areas of science curriculum and peer relation except for the science teacher area. This is because a differentiated science curriculum was designed through analysis of achievement standards, and various teaching methods of student-centered were implemented to reach achievement standards. We hope this study will focus on the impact of backward design 2.0 on learners in elementary science classes and help find ways to effectively apply backward design 2.0 in the field.
Mathematics problem based learning(PBL), which has recently attracted much attention, is a teaching and learning method to increase mathematical ability and help learning mathematical concepts and principles through problem solving using students' mathematical prerequisite knowledge. In spite of such a quite attention, it is not easy to apply and practice PBL actually in school mathematics. Furthermore, the recent instructional situations or environments has focused on student's self construction of their learning and its process. Because of this reason, to whom is related to mathematics education including math teachers, investigation and recognition on the degree of students' acquisition of mathematical thinking skills and strategies(for example, inductive and deductive thinking, critical thinking, creative thinking) is an very important work. Thus, developing mathematical thinking skills is one of the most important goals of school mathematics. In particular, recently, connection or integration of one subject and the other subject in school is emphasized, and then mathematics might be one of the most important subjects to have a significant role to connect or integrate with other subjects. While considering the reason is that the ultimate goal of mathematics education is to pursue an enhancement of mathematical thinking ability through the enhancement of problem solving ability, this study aimed to implement basically what is the meaning of the integrated thinking ability in problem based learning theory in Mathematics. In addition, using historical materials, this study was to develop mathematical materials and a sample of a concrete instructional guideline for enhancing integrated thinking ability in problem based learning program.
The purpose of this study is to investigate the learning achievement of students who has taken the play-based and activity-oriented programs in the class. These new science class programs and instrument to measure student learning achievement were developed for the "Constellation Favorite" lesson of 4th grade students and Those are verified by science education experts, teachers in serve. The subjects of this study consist of 121 students in four classes who were selected on the basis of midterm examination result before teaching treatment. They were divided into two categories with two classes per each category, one class for experimental group and the other class for control group. The experimental groups were given five classes including five play-based class programs. The control groups were given five conventional instruction-type classes. The students were given questionnaires to test their interest ratings. The results show about 17% increase of their learning achievement with (p<0.005) by independent sample T-test method and 40% increase of interest rating in play-based class sample compared to normal class sample. In conclusion, the play-based science class program is found to enhance the students' learning achievement and to interest the students more effectively.
1 Intonation is important. It cannot be ignored. To convince students of the importance of intonation, we can use sentences with two very different interpretations according to intonation. Example: "I thought it would rain" with a fallon "rain" means it did not rain, but with a fall on "thought" and a rise on "rain" it means that it did rain. 2 Although complex, intonation is structured. For both teacher and student, the big job of tackling intonation is made simpler by remembering that intonation can be analysed into systems and units. There are three main systems in English intonation: Tonality (division into phrases) Tonicity (selection of accented syllables) Tone (the choice of pitch movements) Examples: Tonality: My brother who lives in London is a doctor. Tonicity: Hello. How ARE you. Hello. How are YOU. Tone: Ways to say "Thank you" 3 In deciding what to teach, we must distinguish what is universal from what is specifically English. This is where contrastive studies of intonation are very valuable. Usually, for instance, division into phrases (tonality) works in broadly similar ways across languages. Some uses of pitch are also similar across languages - for example, very high pitch may signal excitement or urgency. 4 Although most people think that intonation is mainly about pitch (the tone system), actually accent placement (tonicity) is probably the single most important aspect of English intonation. This is because it is connected with information focus, and the effects on interpretation are very clear-cut. Example: They asked for coffee, so I made them coffee. (The second occurrence of "coffee" must not be accented). 5 Ear-training is the beginning of intonation training in the VeL approach. First, students learn to identify fall vs rise vs fall-rise. To begin with, single words are used, then phrases and sentences. When learning tones, the fIrst words used should have unstressed syllables after the stressed syllable (Saturday) to make the pitch movement clearer. 6 In production drills, the fIrst thing is to establish simple neutral patterns. There should be no drama or really special meanings. Simple drills can be used to teach important patterns: Example: A: Peter likes football B: Yes JOHN likes football TOO A: Mary rides a bike B: Yes JENny rides a bike TOO 7 The teacher must be systematic and let learners KNOW what they are learning. It is no good using new patterns and hoping that students will "pick them up" without noticing. 8 Visual feedback of fundamental frequency with a computer display can help students learn correct patterns. The teacher can use the display to demonstrate patterns, or students can practise by themselves, imitating recorded models.

An increasing number of educators emphasize the affective domain in learning. Affective and cognitive objectives interact and can not be separated from each other. Good emotions and feelings assist students achieving optimally in the cognitive domain. Emotional intelligence harmonizes well with an affective science curriculum. The purpose of this study was to explore the effectiveness of EQ(Emotional quotient) improvement program on students' EQ, science achievement, the science related attitudes, and science anxiety. A pretest-posttest control group design was employed. Subjects were 168 male and female first grade students in a middle school. A control group was instructed with a traditional teaching method, and an experimental group was instructed using EQ improvement program. Two groups were treated for 42 hours during 14 weeks. Two way ANCOVA and correlation analysis was performed using the SPSS. The results indicated that students who received EQ program got higher EQ and their science anxiety was lowered than students who were in a control group(p<.05). EQ program was not significantly effective on science attitude than the traditional instruction but, in the domain 'the enjoyment of science class' it was effective(p<.05). EQ program was significantly effective on students' achievement than the traditional instruction(p<.05).

Recent studies have shown that teachers should have be aware of and understand students' misconceptions, which is one of the major components of PCK. However, teachers often have difficulties in understanding misconceptions and in applying appropriate instructional strategies to change misconceptions. Thus, we designed a method course for pre-service teachers (PSTs) adapting the concept of "teacher as researcher". In the course, PSTs conducted research to investigate students' misconceptions in physics. Twenty-five female PSTs participated in the study. They went through the research process including creating question items, administering items to their target populations, collecting and analyzing student responses, and writing a research paper. Data source included individual interviews with the PSTs, field notes during classroom observation and PSTs' research papers. The results were as follows. First, the PSTs confirmed students' misconceptions and learning difficulties in physics. They experienced discrepancies between their conjecture and research findings. Second, PSTs developed the sophisticated understanding of students' misconceptions and appropriate teaching strategies. Third, the research experience provided the PSTs opportunities to reexamine their physics content knowledge while creating items and explaining scientific concepts. They realized that physics teachers should develop sound understanding of physics concepts for guiding students to have less misconception. Lastly, they realized the necessity of being a teacher as a researcher.
The purpose of this study is to offer the basic materials for the development of nutrition education programs for youth and help domestic science teachers in schools implement effective dietary education by examining youth's purchase behavior of processed foods. As a result of figuring out youth's purchasing behavior of processed food and the difference in accordance with social, demographic variables, they considered taste and price mainly when choosing foods. The results showed that what they consider important when checking food display information was shelf life and price. It was observed that 56% of them check additives display information in food when purchasing processed food. In terms of demographic factors, the more likely they are a girl student, the lower grader they are, and the lower price they purchase processed food at, the better they used the nutritional knowledge learned in school. Based upon these results, it is necessary to offer the consumer's level of education and training for their demands by accurately figuring out youth's purchasing behavior of processed foods. For this, home economics education must allow youth to lead healthy diet by implementing a systematic and professional training on food additives on a basis of the research and utilization of a variety of educational media and teaching and learning methods.
This study aims to suggest implications on develop and operate NCS curriculum by analyzing of differences in perception and educational needs of university students, graduates, human resource managers(HR managers) on NCS basic job skill. The respondents of survey are composed of 533 university students in K university, 730 graduates and 106 HR managers. The major findings are as follows: first, the results showed that the importances of all competencies recognized by HR managers was higher than those of university students and graduates. And graduates perceived their level of competencies as higher than those of university students. Second, the needs for self-development skill, technical skill, and problem-solving skill was the highest within the students and graduates, meanwhile, the needs for the mathematical skill, resource management skill, and the organization understanding skill were low. In contrast, the results of this study showed that the HR managers has the high needs for self-development skill, communication skill and problem-solving skill. Also, HR managers has the low needs for mathematical skill, resource management skill, information skill, technical skill, organizational understanding skill, and job ethics. Based on the above results, we proposed the necessity to develop and apply the NCS curriculum considering the education needs recognized by current students, graduates, and HR managers.
