This study investigated the purpose and role of class evaluation standards and the reason to develop these teaching standards using literature review, survey, classroom observation and teacher interviews. Based on the teachers’opinion, we also investigated who should develop teaching standards and who will benefit most from the standards. In sum, the standards for teaching evaluation should help to form (a) the guidelines for beginners, (b) the directives for specialists, (c) the principles for grasping areas for improvements, and (d) the means for communicating with other communities. In addition, teachers should take responsibility for developing teaching standards as the basis for evaluating their own work and improving their own professional learning to provide quality assurance. The development of subject specific teaching standards is not possible without active participation of teachers as well as other stakeholders in education.

The relationship of maternal separation anxiety, availability of support system and child gender to initial preschool adjustment was examined. Data were collected on 72 middle-class Korean children(35 boys, 37 girls) between the ages of 31 months and 60 months who were entering preschool. Subjects were from intact families, all with non-working mothers. Mothers completed the Maternal Separation Anxiety Scale(MSAS) and indicated the number of extended family members in the home as an index of social support. Classroom teachers completed the Preschool Behavior Questionnaire (PBQ) for each child after the first 2 weeks and again after 6 weeks of school. Each child was observed by the research team during the first 2 weeks of school and again after the 6th-week using the Child Observation System (COS). Applying the COS observed behavior was classified as being in the dependent, neutral, or active mode. All instruments were culturally relevant as validated by Korean experts. Maternal Separation Anxiety was a significant predictor for girls only, accounting for 11% of initial COS variance (p=＜.05). In contrast, social support was a significant predictor for boys only, accounting for 28% of initial PBQ variance when entered after MSAS(p=.005). A significant difference between initial and 6th-week adjustment was obtained in the expected direction on the COS with behavior improving with time (t=-4.06, p=.001). Although a significant difference between initial and 6th-week PBQ adjustment was also obtained (t=-3.63, p=.001), it was not in the direction expected, problematic behavior were found to increase with time. Cultural and developmental factors help explain the findings. Given the patrilineal social system in Korea, boys are highly preferred over girls. Thus the at-home support system, comprised primarily of grandparents, may have a significant influence on school adjustment particularly of first-born sons. In contrast, since girls are viewed as fragile and vulnerable, mothers may express greater separation anxiety about girls. Finally, as would be expected, older children may be able to develop coping skills more readily than younger ones, as child adjustment on the COS significanlty improved over the 6-week period.

The purpose of this study was to examine the relations between the quality of teacher-child relationship, child temperament, and teacher-child interaction. The subjects were 51 3-4 years old children who were attending a preschool in Seoul and their mothers. The mothers of the young children rated child temperament and the head teachers of the children evaluated the quality of teacher-child relationship. The frequency of teacher-child interactions in the classroom was collected through observation during self-selected activities in the classrooms. Observational data included frequency of teacher-initiated interactions and number of child-initiated interactions. The results showed that boys were more likely to have conflictual relationships with teachers and girls were likely to have close relationships with teachers. And lower levels of effortful control were associated with teacher-child conflict. More child-initiated interactions were related to the conflict relationships with teachers. Results suggest that child characteristics and teacher-child interactions contribute to children's relationships with teachers.

Recent technological advancements, along with an increase in mobile Internet access, have spurred on significant developments in the production of e-textbooks. This case study explored the affordances of an iPad e-textbook through teacher and student experiences in English lessons using observation and interviews. The results showed that English learners and teacher benefited from handy and quick web access and the all-in-one features of the e-textbook (dictionary, hyperlinks, and note-taking functions). However, information oversupply by the e-textbook confused students' learning and both students and teacher pointed out technical difficulties in using the e-textbook. In order to implement English pedagogy with technologies such as iPad e-textbooks, teachers should be equipped with the relevant technical skills and content knowledge in order to assist them in becoming autonomous learners in the digital classroom.

The purpose of this study was to investigate the perceptions and perspectives on meanings and use of manipulatives in mathematics lessons. For the investigation, the researcher reviewed related literature and analyzed the perceptions of preservice teachers on the meanings and use of manipulatives in mathematics lessons. The participants were 75 preservice elementary school teachers who took a teaching practice course at the 1st or the 2nd semester in 2015. These preservice teachers observed mathematics lessons for two weeks during the student teaching periods. They were requested to observed the use of manipulatives in mathematics lessons and wrote about their ideas on the meanings and use of manipulatives. Result of the research was that the perceptions on the meanings and use of manipulatives from the preservice teachers' perspectives are as follows. Manipulatives in mathematics lessons were self-made or pre-made manufactures. The using time of manipulatives during lessons varies, and the teachers provide the manipulatives with contexts. Providing in-depth observation during a teaching practice course is allowed opportunities for preservice teachers to reflect their mathematics teaching and learning methods in the classroom.

Flipped learning is necessary for modern education but quite difficult to implement. In pedagogical science, the question remains to what extent the practical work of the teacher in combination with the technologies of flipped learning will improve the quality of higher education. The aim of this article is to study the effectiveness and feasibility of using flipped learning technologies, assessing their perception by students (advantages and problems), identified an algorithm for introducing flipped learning technology in higher education institutions. Research methods. The main method is an experiment. An evaluation of the effectiveness of the study was conducted using a questionnaire and observation method. Statistical methods were used to evaluate the results of the experiment. The research hypothesis is that flipped learning allows the teacher to spend more time on an individual approach, to understand the real needs of students, and provide effective feedback, thereby improving the quality of learning and motivation of students, especially while studying complex material. The results of the study are to prove the effectiveness of the technology of flipped education in the study of complex disciplines, courses, topics. The use of flipped learning strategies improves the self-regulation of the educational process, group work skills, improves students' ability to learn, overcome difficulties. The technology of flipped learning in the presence of modern technical means and constant work on improving the level of digital literacy is an effective means for students to master complex topics and problematic issues that require additional consideration and discussion. The perspective of further research is the consideration of integrated approaches to the application of flipped learning technologies to the principles of STEAM-education, multilingual and multicultural programs, etc. It is also worth continuing to develop a set of methods aimed at enhancing the student's learning activities, the formation of group work skills, direct participation in creating the foundations of higher education.

Introduction: Training standards for long-haul truck drivers (LHTD) are rapidly evolving in Canada, yet the opinions of the drivers themselves have not been adequately considered. The purpose was to survey LHTD on their work training history and to examine LHTD perceptions of driver training and licensing protocols. Methods: LHTD were recruited across two Western Canadian provinces from seven different truck stops. The sample completed 207 surveys and 67 semi-structured interviews. Results: The average age of the participants was 52.5 ± 11.5 years (range 24-79); 96% were men. Approximately 33% of the LHTD had at least one crash. Those who did not receive formal driver training were significantly more likely to crash than those who had received training. Participants stated that current training standards are inadequate for the industry, particularly for new drivers. According to participants, entry-level curriculums should consist of both classroom and practical training, as well as on-road observation with a senior mentor. LHTD reported that many new drivers are not equipped to drive in various contexts and settings (e.g., mountains, slippery roads). Conclusions: LHTD are not confident in the current training guidelines for novice truck drivers. Revisions to the training curriculum and standardization across Canada should be considered. Practical Application: A federal mandatory entry-level training program is needed in Canada to ensure that all new LHTD ascertain the necessary skills to drive safely. Such a program requires government involvement and input from LHTD to facilitate appropriate licensure and consistent training for all drivers.

The purpose of this study is to analyze pre-service science teachers' pedagogical content knowledge. For this study, two senior education students were selected. The data of this study were collected through interviews, CoRe questionnaire, and classroom observation recordings during the period of student-teacher practice. Data were analyzed using the constant comparative method. The results indicated that the two pre-service science teachers had low level pedagogical content knowledge. Two pre-service science teachers' knowledges of science curriculum were different from each other. Orientations toward teaching science shifted to undesirable direction after the experience of a student-teacher's practice-teaching. Their subject matter knowledges were imperfect. They also had low levels of knowledge of students' understanding.
