This study aims to compare student self-, teacher-, and objective assessments of elementary science-gifted students' scientific creativity. A science-gifted program on the topic of Hydraulic Machine was implemented to 40 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The products of the students' activities were assessed by three types of 'Student Self-Assesment', 'Teacher-Assesment', and 'Objective Assessment using Formula'. Based on two essential components of creativity, the scientific creativity is divided into two parts of originality and usefulness. Ideas that satisfy both components can be counted as scientifically creative. The main results of this study are as follows: First, the scores of each week and the average of the overall four-week scores on scientific creativity were significantly correlated. Student self-assessment (r=.687), teacher-assessment (r=.715), and objective assessment (r=.724) appeared consistently over instructional periods. Second, the average scores of student self-, objective, and teacher-assessments were 73.15, 35.72, and 26.60, respectively. The result of student self-assessment on scientific creativity tended to be higher than those of formula and teacher. Third, among the three types of assessment on scientific creativity, a strong correlation appeared between teacher- and objective assessment (r=.974), but neither between student self- and objective (r=.161) nor between student self- and teacher- (r=.213). Fourth, the scores on originality component had a positive correlation between teacher- and objective assessment (r=.713). The scores of student self- and teacher-assessments had a significant correlation too (r=.315), but not between student self- and objective assessment (r=.279). Fifth, the scores on usefulness component did not have a significant correlation between student self- and teacher-assessment (r=.155). Sixth, there was no significant difference on scientific creativity between student self- and objective assessment [${\chi}^2$(1, n=40)=1.667, p<.197]. Not between student self- and teacher-assessment either [${\chi}^2$(1, n=40)=1.616, p<.204]. On the contrary, there was a significant difference between teacher- and objective assessment [${\chi}^2$(1, n=40)=32.593, p<.000]. Seventh, the students were categorized into four groups according to the levels of their scores by student self- and teacher-assessment. The result showed that factors influencing student self-assessment are inherent in the personality traits of gifted individuals, such as self-esteem and perfectionism. The findings suggested that there are challenges for the educators to make efforts to construct consistent assessment methods for scientific creativity.

For an appropriate assessment in mathematics, students should play an active role in their learning by becoming aware of what they have learned in mathematics and by being able to assess their attainment of mathematical knowledge. The process of actively examining and monitoring students' own progress in learning and understanding of their mathematical knowledge, process, and attitude is called self-assessment, Researchers in mathematics education have found some important facts about the meta-cognitive process which is related to self-assessment : i. e. meta-cognition progress is composed of being aware of ones' own personal thinking of content knowledge and cognitive process(self-awareness) and engagement in self-evaluation. Tipical method for self-assessment in mathematics developed upon above finding about meta-cognitive progress is describing about students' knowledge and their problem solving strategies. In the beginning of the description in mathematics about themselves, students are required to answer which part they know and which part they don't know. Self-assessment of students' attitudes and dispositions can be just as important as assessment of their specific mathematical abilities. To make the self-assessment method a success, teachers should let students' have confidence and earn their cooperation by let them overcoming fear to be known the their ability to other students. In conclusion, self-assessment encourages students to assume an active role in development of mathematical power. For teachers, student self-assessment activities can provide a prism through which the development of students' mathematical power can be viewed.

This study aims to compare self- and peer-assessments of science-gifted elementary students' scientific creativity. A science-gifted program on the Pascal's principle was implemented to 40 fifth-graders in the Science-Gifted Education Center for two weeks. After that, students presented their results from a scientific creativity task using the principle in class. The task was to devise a new and useful tool using the principle, and it included the students' self-assessment about their idea. During presentation, students were asked to assess the works of peers and write down the reasons that they gave the scores they gave. Shortly, student self- and peer-assessments about students' scientific creativity outcomes were compared. Based on two essential components of creativity, ideas that satisfy both originality and usefulness can be counted as scientifically creative. The main results of this study are as follows: First, the average scores of student self- and peer-assessments were 71.5 and 61.9. Second, the standard deviations of student self- and peer-assessments were 14.47 and 5.79. Third, among scientific creativity, originality, usefulness scores, only originality had a significant correlation between student self- and peer-assessment (r=.42). Fourth, the students were categorized into four groups according to the levels of their scores by student self- and peer-assessment. And the frequencies of peer-assessment group had a significant difference at p<0.05 level, according to self-assessment group (Chi Square=4.0000, df=1, p=0.0455). Fifth, through a case study by group, the results suggesting that self-assessment could be affected by the students' self-efficacy and perfectionism and such effect could also influence peer-assessment have been found. The result showed that how the student self- and peer-assessment of scientific creativity are different and what the students' thoughts on the evaluation of scientific creativity are. The findings suggested that there are several things to consider for the educators to make efforts to construct consistent assessment methods for scientific creativity.

Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using $x^2$-test (Fisher's exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.

This paper presents a method for accurate camera self-calibration based on SIFT Feature Detection and image quality assessment. We performed image quality assessment to select high quality images for the camera self-calibration process. We defined high quality images as those that contain little or no blur, and have maximum contrast among images captured within a short period. The image quality assessment includes blur detection and contrast assessment. Blur detection is based on the statistical analysis of energy and standard deviation of high frequency components of the images using Discrete Cosine Transform. Contrast assessment is based on contrast measurement and selection of the high contrast images among some images captured in a short period. Experimental results show little or no distortion in the perspective view of the images. Thus, the suggested method achieves camera self-calibration accuracy of approximately 93%.

Purpose: The self-assessment ability of students is important in acquiring clinical skills. The study explored the self-assessment behavior of nursing students after OSCE (Objective Structured Clinical Examination). Methods: The participants were 90 nursing students. They assessed their performance just after an OSCE (assessment 1). They were given OSCE checklists and re-assessed their performance level (assessment 2). Assessments 1, 2, and an assessment by professor were compared and analyzed. Results: Students assessed themselves higher than professor. But, when students were divided into three groups according to score level, different behaviors were evident between the groups. The high-score group assessed themselves lower than the professor, while the mid-and low-score groups assessed themselves higher than the professor. Students' self-assessment more closely approximated the professor's assessment when they were given checklists. The correlation between assessments 1 and 2 was stronger in high-score group and weak in low-score group. Conclusion: The study results indicate that students tend to assess their skills higher than the professor, but their scores were more in line with the professor when they were provided with checklists, and students' self-assessment behavior differed in the different score groups, suggesting a need for customized feedback and a concern for students with low scores.
