The 2015 revised mathematics curriculum requires students to deal with graphs in their first year of middle schools before learning functions so that they can draw and interpret graphs in real-life contexts without being tied to algebra. However, the analysis of graph tasks in the textbook shows that although various context-based tasks are presented, the task of selecting variables in relation to graph composition is insufficient, the ratio of graph-composition tasks is low compared to graph-interpretation tasks, and the proportion of graph inference tasks is very low. In addition, a problem situation of each task tended to be presented piece by piece without being linked. In this study, by reinterpreting the graph tasks presented in the textbook and reflecting the implications from the analysis results, we presented and suggested the method of learning the graph unit teaching using the robot sensors so that students can perform meaningful graph composition, interpretation, and reasoning activities. Meanwhile, since the data logging activities using sensors of the robot proposed in this study are also practicable through VRT(Virtual Robotics Toolkits), they are expected to be applicable to the recently active non-face-to-face classes.","PeriodicalId":198625,"journal":{"name":"Journal of Curriculum and Evaluation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114757543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey was conducted online on 454 teachers from elementary schools, 191 from middle schools, and 227 from high schools to evaluate the teachers’ competency for student assessment, The scale of teacher's competency for student assessment is composed of the following: “planning assessments and developing tools”, “assessment adminstration”, “feedback”, “ethics and compliance with legal procedures”. In order to investigate the variables affecting the teacher's competency of student assesment, the general linear model analysis was employed using teachers’ sub-competencies of student assessment as dependent variables; teachers’ school levels, gender, years of teaching, whether or not to take a subject related to student assessment and the types of training/workshops participated in as independent variables. The results of analyzing the general linear mode have shown that school level, gender, years of teaching, some training/workshop related to students assessment participation were statistically significant, whereas taking courses related to student assessment at the university and training/workshops for student assessment did not affect the teacher's competency for student assessment. Nonetheless, it was found that the average competency of the teachers who took courses related to student assessment was higher than that of those who did not take such courses. The comparison of the teachers’ competence according to their participation in training/workshops has indicated that taking the courses related to curriculum, teaching and learning, and subject competency partly affected the teachers’ sub-competency of student assessment while no such difference was observed in taking the student assessment training/workshops. Based on the results, in order to improve the competency, we need to understand the teacher competency for student assessment by school levels that teachers attend. Also the standards of the teachers competency for student should be developed with consideration for school levels. Since the student assessment courses at the university offer the basic skill and knowledge for pre-service teachers, universities should develop and provide high quality programs for student assessment. Training/workshops related to student assessment should be reconstruct to enhance the teacher's competency for student assessment Lastly, it is necessary to develop specific and detailed training/workshops focused on sub competencies rather than overall competencies for student assessment.","PeriodicalId":198625,"journal":{"name":"Journal of Curriculum and Evaluation","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133637389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to examine the use of the five curriculum online support systems, a total of 3,391 teachers (860 elementary school, 1,223 middle school, and 1,308 high school) who are the target users of the systems were surveyed. The results of the survey were as follows. First, the main means for acquiring curriculum information was through ‘online systems operated by government’, with the highest user rate at 40.8%. Second, curriculum online support systems were utilized the most in the order of ‘School Information’, ‘National Curriculum Information Center’, ‘Edunet T-clear’, ‘Student Evaluation Support Portal’, and ‘High School Credit System’. Third, the reason for using an online curriculum support system was to plan the curriculum, which was the reason ranked in the top three for all the sites. It was found that ‘National Curriculum Information Center’ and ‘High School Credit System’ are mainly being used to understand the national curriculum, when setting the direction for school curriculums. For an in-depth analysis on the use of curriculum online support systems, a monitoring group of 25 educational officers in cities and provinces and 51 elementary/middle/high school teachers (total of 76) was formed. The study suggested what menus, functions, and practices for curriculum organization and implementation need to be supplemented or added to the five websites.","PeriodicalId":198625,"journal":{"name":"Journal of Curriculum and Evaluation","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123804583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially, the improvement conception which is regarded as a core feature of ‘Assessment for Learning(AfL)’ and the structural relationships with its antecedent variables such as formative assessment experience and mastery goal orientation were scrutinized. Structural equation modeling analysis was used to analyze data collected from a sample of elementary and secondary pre-service teachers(N = 557) from teachers’ colleges located in four districts of Korea. The results were as follows. By the latent mean analysis, the conception of assessment for learning was not significantly different across elementary and secondary pre-service teachers. Second, the structural relationships between pre-service teachers’ improvement conception and its antecedent variables were equivalent across the two groups. Thirdly, the formative feedback had a positive effect on the quality of feedback and mastery goal orientation, while it did not make any significant direct effect on the improvement conception. The effects of the three mediating variables such as the quality of feedback, use of feedback and mastery goal orientation between the formative feedback and the improvement conception were statistically significant. Finally, the educational implications for developing pre-service teachers’ positive conceptions of assessment were discussed and this paper concludes with importance of the formative assessment experience for per-service teachers’s conceptions and practice.","PeriodicalId":198625,"journal":{"name":"Journal of Curriculum and Evaluation","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to find the direction of music concept guidance in the subject of 'music appreciation and criticism'. To this end, we examined the theoretical background of applying high school musical cognition development and musical concept to teaching and based on this, we identified the essence of the 'music appreciation and criticism' teaching and what should be considered in teaching and by comparing the curriculum of 'music' subject with 'music appreciation and criticism'. Through this process, the direction of music concept guidance for 'music appreciation and criticism' was divided into the application of music concept and music concept teaching as a presentation of the contents of the curriculum.

N evertheless, there are few research related to the effects of the feedback environment in the classroom assessment of Korea. T herefore, in this study, we utili z ed the Feedback Environment Scale for Students(Steelman et al., 2004), and validated it for use with elementary, middle, and high school students in Korea. We also investigated construct e q uivalence of this scale across the school levels. For this study, reliability analysis, confirmatory factor analysis ( C FA), correlation analysis, and multi- G rou p C FA were a pp lied to check the p sychometric p ro p erties of the K-FESS. First, the K-FESS with 23 items was acce p ted that only one item had been excluded from the original version through translation and content validation p rocedure. Second, the five-factor solution was p roduced by C FA and it exhibited good reliability and validity. T hird, the construct e q uivalence of the K-FESS across the school levels was confirmed. T his means that the K-FESS can be used as a common scale for all school levels. Fourth, the latent mean analyses revealed that the elementary school students had significantly higher feedback environment p erce p tions than those in other school levels.
