The goal of this study was to examine the current status of science teachers’ stage of concern (SOC) and level of use (LoU) on descriptive assessment and determine the relationship between SoC and LoU. To achieve this, concerns-based adoption model (CBAM) was used, and a survey was conducted on 138 science teachers. The data from this study were analyzed by frequency analysis, percentile analysis based on CBAM, χ² test, and Spearman correlation analysis. SoC and LoU of the science teachers observed in this study are as follows. First, the science teachers’ overall SoC for the descriptive assessment was low and showed a typical pattern of the initial stage when the program was introduced. Second, LoU analysis on descriptive assessment showed that the “mechanical Use” (N=49, 35.5%) or “routine” (N=48, 34.8%) accounted for the majority. Third, the Spearman correlation between SoC and LoU on descriptive assessment was .299(p<.01). This suggests that teachers’ SoC needs to be increased in order to promote higher LoU on descriptive assessment, which requires new alternative measures.

This study aimed at investigating elementary teachers' stages of concerns and its changes about STEAM education. The participants of this study were 90 elementary school teachers implementing STEAM education in their schools. The Stages of Concern Questionnaire (SoCQ) was administered after the permission was granted by Hall. Data were collected three times from April, June, and December in the year of implementing the exemplary STEAM school. The results indicated that elementary school teachers' concerns toward STEAM education, the differences of the percentile scores of each stages of concerns, showed slightly low. The SoC of teachers in April showed that Awareness(Stage 0) was relatively very high and Consequences(Stage 4) was very low. However, in December, both Awareness(Stage 0) and Management(Stage 3) were very low. In particular, the percentile scores of Consequence(Stage 4) showed the big difference from 54.7 to 74.3. In addition, teachers who took science track in their high schools showed the relatively low score in the stage of Management(Stage 3). Teachers having the degree of Master of Arts presented the relatively low percentile score in the stage of Management(Stage 3). Teachers who majored in STEM related areas at the university presented the relatively low score in the stage of Management(Stage 3). The findings of this exploratory study may provide the useful insights into the integrative approaches of STEAM education.

The purpose of this study is to analyze the case in which we can identify how the SoC of Practical training teachers about the instructional media changes and why these change appears during the child care practice when we assumpt that for Practical training teachers to use the instructional media is that they participate in change during child care practice. In case A, the SoC moves from Stage 0 to Stage 1, Stage 6. In case B, the SoC moves from Stage 0 to Stage 2. In case C and D, the SoC of the Practical Training Teachers are not changed. Above this, we identify the SoC of Practical training teachers. Case A and B change the SoC, but Case C and D does not change the SoC after child care practice. We identify that the reason why there are differences is that according to (1) the training of the perception of practical training teachers, curriculum, knowledge related to instructional media before child care practice, and (2) time, the SoC of practical training teachers about instructional media is changed. In the end, we make a suggestion for the following research. First, a comparative study will be made of other students of the department for child care in the same college or other college. Second, we need to make a study for analyzing SoC profile after supporting instructional assistances.

The purpose of this study is to analyze on high school teachers' stage of concern(SoC) on 'Creative-Experience Activity' in 2009 revised national curriculum and investigate the improvements of their levels. The subjects for this study were 234 high school teachers through out all part of the Korea country. The instrument for this study was developed according to the Hall & Hord(2006)'s stage of concerns questionnaire of Stage of Concern. The Data were analyzed by Profiling of teachers' concern and one-way ANOVA. The major findings of this study were as follows: First, 85.25% of the high school teachers were in stage of Awareness. 6.34% of teachers were in stage of Information. Most of high school teachers' concern about 'Creative-Experience Activity' was generally 'non-user' stage that unconcerned. Second, there were not significant differences in teachers' stage of concern according to their sex and teaching career except for region. In region, the teacher in metropolis tent to interest getting new information than small and midium size city. We need to make an effort to transfer from 'non-user' stage to 'early-user' stage of and 'impact' stage. To do so, we may sublate too much curriculum revise and start teacher training for 2009 revised 'creativity-experience activity' curriculum. The result of the study provide that there are not curriculum implementation success without teachers' concern about revised curriculum.

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.

This paper concerns the study of a two-stage binary absorption cycle employing the refrigerant/absorbent combinations of $LiBr/H_2O$ and $NH_3/H_2O$. This cycle consists of coupling two single-effect absorption cycles so that the first stage absorber and condenser produces heating water to evaporate refrigerant in the evaporator of the second stage. The effect of operating variables such as evaporator temperature, condenser and absorber temperature, and generator temperature on the coefficient of performance and temperature lift have been studied for two-stage binary absorption heat pump systems. It is found that this cycle has a large temperature lift at $105^{\circ}C$ of optimum generator temperature to obtain $50^{\circ}C$ of condenser temperature.

Even though software (SW) education has not been considered part of the current national kindergarten curriculum, in practice there is growing interest in adopting it. Teachers would be expected to play a key role in the successful introduction and implementation of new educational changes, such as SW education. In preparation for its adoption in ECE, it would be useful to determine ECE teachers' perception and attitudes toward early childhood software education. For this study, 219 ECE teachers' level of concern toward SW education was surveyed using the Stages of Concern Questionnaire. It was found that the teachers' level of concern was the highest at stage 0-Unconcerned and that they had high levels of stage management, personal and informational concern. Thus, a non-user pattern was mostly indicated. However, compared to the typical non-user pattern, the pattern aspect close to critical non-user ever appeared to some extent. In addition, a significant difference in the level of concern was shown at all stages depending on the awareness of the necessity for SW education. The teachers with SW training experience showed a higher intensity only at stage 0. There was a statistically significant difference in stages 0 and 6 depending on the future implementation decision. These results will be utilized as a resource in building an ECE teachers' support system according to their level of concern about SW education.

The purpose of the study was to figure out elementary school teachers' Stages of Concern(SoC) between senior teachers and new comers to integrated units of integrated curriculum which was revised in 2007 and applied in 2009 by using CBAM. Seventy-four home-room teachers in elementary schools took part as participants. For data collection, as Hall and Hord suggested in 2005, Questionnaire of Stages of Concern was used. Profiling of teachers' concern and one-way ANOVA were employed in data analysis. In the results, 55% of the teachers were in the stage of Awareness. In the stage of Informational, 22% of the teachers were appeared. Most of elementary teachers' concern about integrated units was closed to indifference of self-interest level. The difference of concern between senior teachers and others will be illustrated as findings. The results of the study provided that factors which influenced teachers' concern about the curriculum. Physical factors such as a curriculum guideline or on-line system to access boarder-cross curriculum influenced teachers' concern. Little intervention about the boarder-cross curriculum appeared in elementary schools. The authors of the study suggested to emphasizing the roles of facilitator for the revised curriculum.

This study surveyed pre-service early childhood teachers' level of concern about software education on the assumption that software education will be introduced into early childhood education in the future. It was shown that the pre-service early childhood teachers' level of concern about software education is the highest at stage 0(95%) and that they have a high level of informative, personal and managerial concern. Thus, a non-user pattern was mostly indicated. However, compared to the typical non-user pattern, their personal and informative level of concern is slightly higher. A 'tailing up' phenomenon to stage 6(refocusing) was shown. Hence, a pattern aspect close to critical non-user appeared to some extent. A difference in the significant level of concern was shown at all stages, except for managerial concern, according to the need for awareness, the appearance of a future implementation plan, and technology efficacy level. Based on this outcome, it was proposed that teacher training in early childhood software education should be made available as part of the educational activity connected with the Nuri Curriculum, since this would be more suitable for young children's developmental level than the early childhood software education, including coding education, etc., currently found in private institutions.

The purpose of this study was to measure middle and high school students' stage of concern(SoC) and their level of use(LoU) on the self-directed learning in science learning based on the CBAM(Concern-Based Adoption Model). Additionally, this research was designed to analyze the difference between the degree of students' SoC and their LoU according to the their background variables. For this, 440 middle and high school students participated in the research. The results of this study were as follow: Firstly, since the students' SoC and LoU about the self-directed learning in science learning are low(Stage0 : awareness and Level II : preparation), we should draw students' immediate concern by developing training programs that would enable them to actually participate in the process of implementing the self-directed learning. Secondly, the students' SoC and LoU on self-directed learning in science learning vary depending on their residence, gender, and grade. This is the reason why we have to develop customized training programs on self-directed learning that suits their background. Thirdly, it shows that students, who have higher concern on self-directed learning in science learning, implement it better than those who are not concerned with it at all. It implies that we need a training program that considers both the students' concern and implementation on self-directed learning in science learning.
