'Science festival' is an annual public event featuring a variety of science- and technology-related workshops and live demonstrations of experiments by student presenters. This study was to explore the student presenters' and student visitors' perceptions of the science festival. The subjects were 323 student presenters who managed laboratory booths and 495 student visitors who attended the festival for six days. We developed a questionnaire based on the modified items of ones both from Ahn & Park (2009) and Lee et al. (2010). Data included students' participation backgrounds, differences of their perceptions about the educational effects according to participation types and school levels, and student presenters' perceptions of scientific inquiry that they had through the preparation of the festival. Findings suggested that student presenters perceived their experience of preparing for the festival as meaningful scientific inquiry process such as asking and solving problems. Based on the results, discussion and implications for communitybased programs as an informal science education were presented.
The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.
The purpose of this study was to examine the status of the field application of the Science II career electives with the application of the 2015 revised curriculum up to the 3rd year of high school. This study focused on examining high school science teachers' perceptions of the student-participatory class and process-centered assessment in Science II subjects, which are career-intensive high school science electives. A total of 192 science teachers responded to the survey questionnaire, and 12 teachers participated in interviews. In the in-depth interviews conducted to supplement the survey results, questions were asked about changes in the overall class, the status of student-participatory classes, and changes in the assessment of Science II subjects due to the emphasis on process-centered assessment. The main research results included teachers' perceptions of changes in teaching and assessment methods with the application of the revised curriculum, the degree to which the eight skills used in Science II classes develop the key competencies of science, and the teaching and assessment methods commonly used in Science II classes. Science teachers generally agreed with the purpose and necessity of introducing student-participatory classes and process-centered assessment, which are the core purpose of the 2015 revised curriculum. However, they had difficulties in practice due to the excessive content of Science II subjects. Problems were also encountered with securing objectivity and fairness during assessments and the operation of online science classes due to COVID-19.
The role of teachers has been explicitly emphasized to implement the vision of sustainable development(SD). Also, it is very important to understand the way student teachers understand SD and how they interpret their own professional task in terms of SD, usually referred to as education for sustainable development(ESD). This study investigated student teachers' perceptions of SD and ESD using group interview. Key findings include, first, that they think SD as development which does not exceed the limits of natural environment, and as wise management of resources/protection of environment for future generations. They also think SD as good thing though they don't understand the contested nature of SD. Second they think ESD as education about SD, but some student teachers say they can't explain ESD. Many student teachers prefer field trip to local examples for both elementary school students and themselves. Also they will teach only what the textbook says about SD and ESD during their school placement and as teachers. So it will be the beginning of ESD in school to include SD in the curriculum for students and student teachers. It is suggested to study student teachers' perception of SD focussing on how they think the relationship between protection of environment and economic growth.
This study aims to find out an effect of 3 types of environment worksheets used for 5th elementary graders's environmental class on their environmental perceptions and behavior. 104 of 5th graders in M elementary school in Ulsan Metropolitan City were selected and divided into A group(35), B group(34) and C group(35) for this study, and to A group, a class used worksheet of the photo taken clean, unpolluted environment, and to B group, a class used worksheet of the photo taken polluted environment and to C group, a class used worksheet of only text without photo were carried out. The worksheet used class was conducted 5 times, and then after the classes, the student's change in environmental perceptions and behavior by group was put into verification Below are the study results. First, the worksheets used for the environment class have incurred significant differences in student's environmental perceptions by their types. A. B groups were higher than C group in their post-test environmental perceptions score, a statistically significant differences. Meanwhile, statistically insignificant differences appeared in environmental perceptions score between A and B groups. Second, the type of worksheet used for environment class represented considerable differences in he students' environmental behavior. A group was higher than B. C groups in post test environment behavior score, the difference of which was statistically significant. While statistically insignificant difference represented in environmental behavior between B, C groups. Third, the both types of worksheets of the photo of positive environment and that of negative environment appeared to be effective statistically in changing the elementary students' environmental behavior, while the worksheets of the photo of positive environment appeared to be effective statistically in their environmental behavior.
Background: This study was conducted as a descriptive-correlational exercise with the aim of determining the effect of student perceptions of social skills on their pro and con perceptions of smoking. Materials and Methods: The study sample comprised 106 students at $6^{th}$, $7^{th}$ and $8^{th}$ grades in three primary schools. The data were collected through socio-demographic data collection form, Social Skill Perception Form and Child Decisional Balance Scale. Data were evaluated by percentage calculation, Student t test and correlation analysis. Results: While the point average of pro perception of smoking of the students with a high point average of social skill perception, was $8.6{\pm}3.1$, in those with a low social skill perception point average it was $10.7{\pm}4.2$, the difference being significant(p=0.012). The respective point averages of con perceptions were $26.8{\pm}3.7$ and $23.5{\pm}3.3$, again significant (p=0.000). While a positive medium level (r=0.410) relationship was determined between the point average of social skill perception and con perception of smoking, a negative low level (r=0.281) relationship was determined with the pro perception of smoking. Conclusions: As the social skill perception point average increases, children's con perceptions of smoking increase and their pro perceptions decrease.
The purpose of this study was to investigate high school students' perceptions of biotechnology. Participants in this study were 9th and 10th grade students who were enrolled in high schools in Gyeonggi Province. The survey instrument used in this study was a 26-item questionnaire that was designed to measure students' perceptions regarding biotechnology. The study revealed that students' perceptions were positive toward the use of biotechnology on biological objects such as plant, grain and microbes. However, their perceptions were negative toward the use of biotechnology on humans and animals. Male students' perceptions were more positive than female students and there were significant differences between male and female students(p<.01). The study also revealed that male and female students had positive perceptions about the use of biotechnology in the development of beneficial products. However, male students' perceptions were more positive than female students(p<.01). Female students' perceptions were slightly more negative than males and they indicated a measure of caution in the development of beneficial products using biotechnology. Regarding the reliability of biotechnological information acquired from food companies, TV broadcasters, and entertainers, male and female students tended to be highly negative. Students perceived that environmental, religious and ethical issues did not affect the use of biotechnology when asked the effect of these factors on the use of biotechnology. They perceived that food safety and genetic factors of microbes did affect the use of biotechnology. Thus, the study findings suggest that teaching and learning strategies based on the differences of perceptions between male and female students of this study be established and the use of media, development of teaching method and materials be promoted in order to enhance student's performance in environmental education.
Based on Perceptions about Mathematics Teachers (PMT) perceived by high school students, measured by 2189 students from Seoul Educational Longitudinal Study 2014 (SELS 2014), latent profile analysis (LPA) identified five distinct types of student groups (positive, partial positive, middle, negative, extreme negative). These student of positive, middle, and negative groups are positive, moderate and negative perceptions about math teachers. Partial positive group generally had a positive perception about mathematics teachers, extremely negative group was very negative about mathematics teachers. Both of these groups had peculiarly inconsistent trends and several anomalies. The Multinomial logistic regression analyses also indicated that individual factors (gender, major, self-concept, resilience, self-assessment, career maturity), school factors (friendship, relationship with school teachers) and parental factors (academic-relationship, emotional-relationship) were significant predictors of PMT profile groups. The Analysis of variance also indicated that mathematics class (attitude, satisfaction and atmosphere), Mathematics achievement were significant predictors of PMT profile groups. The profiling of perceptions about mathematics teachers resulted in enhanced understanding of the complex range of processes students employed. During mathematics class, implementation of smooth interactions and communications between students and teachers added in the teaching and learning of mathematics.
Teacher written feedback on student compositions has received tremendous attention in second language (L2) writing research. Notwithstanding the importance of understanding both teachers' and students' perspectives on the feedback process, much of the feedback research has only looked into one-side of the story - adopting either the teacher's or the student's perspective. The current study is an attempt to look into both sides of the story by examining the types of written feedback that students prefer, the extent to which students' preferences and teachers' actual feedback practice overlap, and the extent to which student perceptions of teacher feedback coordinate teacher self-reflections on their feedback practice. Three English composition classes (3 teachers and 46 students) at a university participated in this study. It analyzed student and teacher data from questionnaires and teacher written feedback on student compositions. The results showed that students' preference for feedback on global and local issues varied across the three composition classes. This is partly a consequence of how students perceived the type of feedback that their teachers practiced. Teacher self-reflection on and student perception of teacher written-feedback generally coordinated. These findings are discussed in light of how contextual factors affect learner perception of teacher written feedback and underscore the need for examining students' reactions to feedback and teacher self-reflection.
The goal of this study was to examine the relationship among students' personal variables(Korean language abilities, self-efficacy, student-teacher attachment relationships), teacher variable(perceptions of multi-cultural education) affecting on multi-cultural students' school adjustment. Structural equation modeling was performed to test the mediating role of self-efficacy and student-teacher attachment affecting multi-cultural students' school adjustment. 336 elementary students and their matching 264 elementary school teachers were participated for this study. The model fit for this study model was acceptable, =280.024, df=98, CFI=.930, RMSEA = .074. The results revealed that teacher's perceptions on multi-cultural education significantly related with student-teacher relationships. However, Korean language ability did not directly affect the school adjustment for multi-cultural background students. That is, self-efficacy and student-teacher relationships mediated between Korean language ability and school adjustment. Moreover student-teacher relationships seem to be the key mediating factor between other research variables and school adjustment. Further considerations and future directions based on results were discussed.
