We investigated perceptions and image analysis on scientists studying small organisms reflected in elementary student's drawing using a modified version of the Drawing-A-Scientist-Test. The participants were 530 of fifth and sixth graders consisted of 449 ordinary students and 81 science gifted students. The data were collected from associated words, images and explanatory notes depicted by students engaged in questionnaires. The results indicated that a larger number of students reminded small sized animals and/or plants as words associated with small organisms. In addition, some students depicted anthropomorphic or abstract microorganisms. In this study, more stereotypes of scientists' appearance were exhibited at sixth graders and city region group. Most of the students depicted indicators such as lab coat, glasses, scientific instruments for observing, indoor, male and young, whereas only a few students depicted collaborative work. There was statistically significant difference between girls and boys, because boys perceived male scientists only, while half of girls depicted female. More frequent research instruments and scientific captions were used when science gifted students depicted scientists studying small organisms. These results could be contributed to education on microorganisms in elementary science.

Many researches proposed different models and concepts for the PCK. It is important to understand its composition. Most studies investigated the development of PCK and its influence on students' learning from the teachers' perspectives. We developed an instrument for assessing middle school students' perceptions of mathematics teachers' PCK (SPOMTPCK) to investigate the nature of PCK. Theoretical claims and empirical research in PCK were used to design questions and sub-scales for the SPOMTPCK. The face validity of the instrument was established by the expert mathematics teachers and students. A questionnaire consisting of 38 items on a five-point Likert-type scale was used for data collection from 799 middle school students. The exploratory factor analyses resulted in the development of a three-factor scale of 17 items that was proved valid and reliable, that is, pedagogical representation, understanding students and curriculum, and encouraging students' engagement. The Cronbach α coefficients of the scale was 0.935, and the Cronbach α coefficient of three factors were ranged from 0.721 to 0.912. The confirmatory factor analysis showed that the questionnaire has good construct validity and the fit indexes are good. MANOVA analysis of variance revealed that the differences in mathematics teachers' PCK identified by students of different school types and grades were statistically significant. It is a validate measurement to evaluate the perceived mathematics teachers' PCK for middle school students.

This study investigated medical students' perceptions of good jobs. We classified medical students' perceptions of good jobs and analyzed the characteristics of each type. The Q methodology was used to extract medical students' subjective thoughts. After extracting statements based on previous studies, 46 Q samples were selected. The P sample consisted of 40 medical students divided evenly by gender and grade. They performed a Q sort of the 46 Q sample questionnaire and the results were analyzed using the QUANL ver. 1.2 program. Very few consensus statements were found in the replies. We divided answers into four types, each of which was clearly distinguished: (1) quality of life-oriented jobs, (2) reward-oriented jobs, (3) service-oriented jobs, and (4) self-realization-oriented jobs. Medical students in type 1 prioritized quality of life equally at work and at home. Medical students in type 2 preferred high-paying jobs. Medical students in type 3 placed importance on serving others. Finally, medical students in type 4 viewed good jobs as involving learning and development. The types of jobs sought were classified according to individual students' values and subjectivity. Medical schools may use the results of this study as a basis for career guidance.

The purposes of this study was to analyze qualitatively changes in students' experience and perceptions in relation to studying science using portfolios and any resultant effects on the portfolio itself. Five fourth-grade elementary students from one small city participated in this study. Data was collected through interviews as well as through student portfolios containing the science content matter of two units over two weeks. Observational diaries recorded by a teacher were also used to test the reliability of data collection. All interviews with students were transcribed to develop a suitable network to categorize students' responses. Students' portfolios were analyzed in order to reveal their essential characteristics in combination with their teacher's observational diaries. The results were as follows. First, student perceptions of their portfolios were categorized into three different levels; superficial, extended, and moderate perceptions. The changes in perception could also be divided into three levels; consistent-superficial, unstable, and a progressive-extended pattern. Second, the experience of students with their portfolio were investigated in terms of the following; successfully completing the elements of the portfolio, development of evidence, interaction with peers, teachers, and parents, and the standards of evaluation used for the portfolios. Third, the perceptions and experience of working on the portfolio by students had a number of direct effects on the way in which students actually created and developed their portfolios. Finally, students with positive attitudes towards their portfolios actively participated in the portfolio experience and finally understood what it meant completely. However, students with negative attitudes regarding portfolio based work, did not leave the experience with any heightened awareness of the utility or indeed, purpose of portfolio based work.

Purpose: This study is to assess the level of student perceptions, academic achievement, satisfaction, and their relationships in a medical-surgical nursing course using team-based learning (TBL). Method: Four-hour TBL sessions were given in a structured three-phase sequence in a cohort of 261 second year nursing students. Results: Mean perceptions of TBL was $6.64{\pm}5.11$, and $8.30{\pm}4.11$ for perceptions of teamwork. On a 7-point scale, the mean satisfaction score was $4.85{\pm}1.41$, and 64.0% of nursing students were satisfied with TBL compared to lecture. Group readiness assurance test score was significantly higher than individual readiness assurance test score (t=-16.76, p<.001). Perceptions of TBL (F=1.40, p=.245), perceptions of team work (F=1.55, p=.202) and satisfaction (F=0.81, p=.489) was not different by the level of students' academic achievement on items related TBL. Conclusion: Results indicates that TBL was an effective instructional strategy including favorable perceptions and satisfaction for nursing students. TBL could be an adjunct educational strategy for undergraduate nursing education.

Free-talking in Korea has recently been emphasized as a way of improving students' speaking ability outside of the classroom. The purpose of this study is to examine perceptions of free-talking, to understand what type of roles were played by or allotted between Korean students and international professors (IPs) and to look for effective speaking strategies for utilizing free-talking. Participants of this study were 68 university students and 23 IPs. The data collected through a survey type of questionnaire were analyzed by this researcher and the main findings indicate that students and IPs have somewhat different viewpoints about their concepts of free-talking. Students expressed varying viewpoints depending on their experience and class (year). In terms of the benefits, usefulness, and satisfaction of free-talking, students and IPs seem to be in more agreement with each other although the two groups have conflicting perceptions in the particular operation of free-talking, especially in terms of preparation and feedback. Students stated that they feel anxious, nervous, and that they struggle with peer pressure while free-talking. However, they feel that through free-talking they build up confidence and increase their speaking ability. Regarding roles, most professors play a helpful role as a guide or facilitator while students want professors to provide more suitable materials and to tutor them by means of appropriate feedback and strategies as well-prepared teachers like a prompter, participant or tutor in the timely manner. Finally, this paper proffers a few practical suggestions for activating free-talking and a discussion of the pedagogical implications.

The purpose of this study was to investigate the effect of the use of video resources on improving listening comprehension. 86 students enrolled in a summer session at a Korean university participated in the study. They were assigned to one of three groups based on the results of their TOEIC test scores: 29 students were assigned to the low group, 29 students to the intermediate group, and 28 students to the advanced group. Each group studied the same lessons using authentic video materials. They were taught for 10 sessions over three weeks. The pre- and post-test design helped to determine whether authentic videos were effective in improving listening skills for all proficiency levels. In addition, a questionnaire investigated students' perceptions toward using video resources. Paired sample t-tests, ANOVAs, and an ANCOVA were utilized to identify significant differences. It was concluded that in the intermediate and advanced proficiency groups, the students' listening skills increased significantly after learning with videos. In addition, listening improvements among the intermediate and advanced students were much greater than those of the low proficiency group. As for students' perceptions toward using video resources for improving their English listening skills, they responded positively. Based on these findings, pedagogical implications are suggested, and future studies will be discussed.

This study investigated middle school students' perceptions of an optimum class size as well as the relationships between a class size and various aspects of students' lives at school. Data were gathered from 858 students from 8 classes (grade 1 and 2) at 4 middle schools located in Busan by administering survey questionnaires. The average class sizes to which each participating students belonged were 17.88, 30.0, 31.88, 28.0 respectively. A series of comparative analyses were carried out, revealing that the majority of the participating students perceived 25-30 as an optimum size for one class. Also, students in a relatively smaller class tended to show higher levels of satisfaction with school lives and with school and classroom facilities, more positive attitudes towards classroom atmosphere, and greater needs for peer interaction than did their counterparts. Furthermore, it was found out that the actual class size had to do with the students' perceptions of the relationships between school facilities and their levels of stress and pleasure at school. These findings were discussed in order to provide educators, architects, and policy makers with practical implications for bringing about a better school environment that is conducive to learning and living for middle school students.

Based on the importance of visual representation for scientific understanding, this study applied visual thinking in elementary science classes. This study analyzed elementary students' visual thinking and investigated the instructional influences. Students' perceptions on the class applying visual thinking were also investigated. The subject were 38 fourth grade students, 18 in experimental group and 20 in control group. For the unit of 'Shadow and mirror', on-line and off-line blended classes were applied in both group because of COVID-19. The experimental group student were asked to construct their own visual thinking, while the control group students used traditional workbook. The results were as follows. First, students' visual thinking can be classified into three different types, which are 'activity recall type', 'result summary type', and 'core concept representation type' based on what they represent rather than how they represent. Second, applying visual thinking in science class showed significant effects on science academic achievement, science related attitude, and creative academic efficacy. Third, students' perceptions on applying visual thinking in science classes were very positive. Students perceived visual thinking activities were interesting and helpful for understanding science. Educational implications of applying visual thinking in elementary science classes were discussed.
