The relationship between non-cognitive student attributes and academic achievements in a flipped learning classroom of a pre-dental science course.

PurposeThe purpose of this study was to examine whether non-cognitive student attributes such as learning style and personality type affected academic performance in a flipped learning classroom of a pre-dental undergraduate science course.Methods‘Biodiversity and Global Environment,’ a 15-week, 3-credit course, was designed as a flipped class in Seoul National University School of Dentistry in 2017. Second-year pre-dental students were required to enroll in the course and to engage in online learning and in-class discussion. The Kolb’s Learning Style Inventory and the Myers-Briggs Type Indicator were conducted to measure non-cognitive student factors. Independent samples t-test and multivariate regression analyses were used to examine the relationships between self-rated measurements and academic achievement.ResultsMore than half of the students enrolled in the flipped science course had an assimilator learning style (50%), followed by convergers (24%), accommodators (16%), and divergers (10%), and their personality types were dominated by the introverted, sensing, thinking, and judging types, respectively. Examining group differences using the t-test demonstrated a significant relationship between the diverger group and higher academic success. In particular, the multivariate regression analysis indicated that both thinking types and female students performed better in discussion than feeling types and male students.ConclusionTo operate the flipped learning classroom more effectively in medical and dental education, the instructor should carefully develop and apply a more tailored facilitation and relevant assessment by considering student learning styles and personality types.

Do Dental Students' Personality Types and Group Dynamics Affect Their Performance in Problem-Based Learning?

The aim of this study was to determine whether the personality types of dental students and their group dynamics were linked to their problem-based learning (PBL) performance. The Myers-Briggs Type Indicator (MBTI) instrument was used with 263 dental students enrolled in Seoul National University School of Dentistry from 2011 to 2013; the students had participated in PBL in their first year. A four-session PBL setting was designed to analyze how individual personality types and the diversity of their small groups were associated with PBL performance. Overall, the results showed that the personality type of PBL performance that was the most prominent was Judging. As a group became more diverse with its different constituent personality characteristics, there was a tendency for the group to be higher ranked in terms of PBL performance. In particular, the overperforming group was clustered around three major profiles: Extraverted Intuitive Thinking Judging (ENTJ), Introverted Sensing Thinking Judging (ISTJ), and Extraverted Sensing Thinking Judging (ESTJ). Personality analysis would be beneficial for dental faculty members in order for them to understand the extent to which cooperative learning would work smoothly, especially when considering group personalities.

Flipped-learning course design and evaluation through student self-assessment in a predental science class

PurposeThis study explores how to design a flipped classroom for a predental science course and evaluate its course through student self-assessment in order to provide practical implications for flipped learning in an undergraduate level. MethodsSecond- and third-year predental students in the Seoul National University School of Dentistry enrolled in Biodiversity and Global Environment, a 15-week, three-credit course based on a flipped learning model. At the end of the course, the students were asked to rate their self-directed learning, attitude toward social media, discussion skills, learning readiness, and class satisfaction. Out of the 82 predental students, 61 (74.3%) answered the survey. Pearson correlation and multivariate regression analyses were employed to examine the relationship between the self-rated measurements and the performance scores. ResultsThe majority of the students felt somewhat more prepared than the medium level before the class (mean score of 3.17 out of 5.00), whereas they expressed relatively low preference concerning social media use and attitude (mean score of 2.49). Thus, it was found that learning readiness was significantly associated with both discussion skills and class satisfaction. In particular, multivariate regression analysis confirmed that learning readiness had a significant influence on learning outcomes. ConclusionThis study offered insights into how to design a flipped learning course in terms of predental students’ preference and their learning readiness. Although learning success in a flipped classroom depends on the students’ self-perceived level of preparedness, much still remains to be achieved in order to apply social media benefits in a flipped learning context.

Predictors of Undergraduate and Postgraduate Clinical Performance: A Longitudinal Cohort Study

Though many medical schools applied various admission criteria in the selection process, the evidence of using those criteria is unclear. This study examined the predictive validity of each admission criterion for student competency. We conducted a prospective cohort study of all students who matriculated to Seoul National University School of Medicine from 2002 to 2008. Demographic characteristics, admission criteria scores, and clinical competencies based on grade point average (GPA), objective structured clinical examination score, and internship score were obtained for each student to analyze the predictive validity of admission criteria. Graduate GPA at the end of 4 years positively correlated with preadmission GPA (p < 0.0001) and written test score (p = 0.012) but negatively correlated with essay test (p = 0.049). Internship score significantly correlated with preadmission GPA and graduate GPA. Regression analysis revealed that the preadmission GPA of the affiliated college and young age at admission could predict GPA, and preadmission GPA and graduate GPA could predict the internship score, which indicates postgraduate clinical performance. These findings suggest that preadmission GPA is a reliable predictor of academic achievement during medical school and postgraduate clinical performance. For assessing nonacademic competencies, further research is needed.

The relationship between dental graduate students' MBTI types and academic achievement in problem-based learning

The study aimed to determine the personality types of the graduate students in Seoul National University School of Dentistry (SNU SD) and analyze the specific personal types that were linked to their performance in problem-based learning (PBL). A total of 263 graduate students in SNU SD from 2011 to 2013, participated in PBL and completed the Myers-Briggs Type Indicator (MBTI) GS form, which was analyzed statistically to determine whether their MBTI personality types were independent of their PBL performance. In particular, MBTI types were regressed on evaluation subcategories, including tutor evaluation and oral test. ESTJ (20.9%) and ISTJ (18.6%) were the most common MBTI personality types in dental graduate students. Compared with males, female students performed significantly better on the PBL. Judging was the most notable type in PBL performance, with its J-P index being statistically significant. PBL is implemented, based on the perspective of student-centered education. Accordingly, the types of personality that usually matriculate in dental school should be monitored, and a student-centered approach to dental education should be adopted.

Who Succeeds at Dental School? Factors Predicting Students’ Academic Performance in a Dental School in Republic of Korea

The purpose of this study was to examine what cognitive and non-cognitive factors were responsible for predicting the academic performance of dental students in a dental school in the Republic of Korea. This school is one of those in Korea that now require applicants to have a bachelor's degree. In terms of cognitive factors, students' undergraduate grade point average (GPA) and Dental Education Eligibility Test (DEET) scores were used, while surveys were conducted to evaluate four non-cognitive measures: locus of control, self-esteem, self-directed learning, and interpersonal skills. A total of 353 students matriculating at Seoul National University School of Dentistry in 2005, 2006, 2007, and 2008 consented to the collection of records and completed the surveys. The main finding was that applicants who scored higher on internal locus of control and self-efficacy were more likely to be academically successful dental students. Self-directed learning was significantly associated with students ranked in the top 50 percent in cumulative GPA. However, students' interpersonal skills were negatively related to their academic performance. In particular, students' lack of achievement could be predicted by monitoring their first-year GPA. Therefore, the identification of those factors to predict dental school performance has implications for the dental curriculum and effective pedagogy in dental education.

Transfer students' personality types and their academic performance in a graduate-entry dental school.

The study was designed to identify how different types of transfer student personality would be constituted in Seoul National University School of Dentistry (SNU SD) and delve into what personal types were often observed more competent in academic performance. Among 40 students who transferred to SNU SD in 2004, 15 students voluntarily participated in completing the Myers-Briggs type indicator (MBTI; GS form); then, it was tested whether or not their MBTI types would be dependent upon their final grades. In addition, another 32 out of the 50 students who were enrolled through a traditional pre-den system served as a control group. It was mainly found that ISTJ type was the most typical one for those transfer dental students as well as for other native dental students who excelled in their academic performance. The noticeable majority of transfer students were Introverted (67%), Sensing (80%), Thinking (86%), and Judging (80%), with S-J pattern being statistically significant. SNU SD has been in a rebuilding process in terms of student/outcome centered dental education to have it up to the global standards. For this reason, it is ultimately a crucial part of that process to understand what personality types of the dental students with different backgrounds in major are observed and thus recognize how to support their learning according to different patterns of individual personality.

A tribute to a deceased genius

This February, an exceptional international symposium on biomaterials was held at the Korea Advanced Institute of Science and Technology (KAIST). The reason for its extraordinariness was not the symposium theme 'Emerging Biomaterials', nor the reputed scientific speakers from around the world, but the commemoration of a respected scholar who had committed suicide a year ago. Professor Tae Gwan Park was a prominent master and mentor of biomaterials research. After graduating from Seoul National University School of Engineering in 1980, he earned his doctorate from the Department of Bioengineering at the University of Washington, Seattle, in 1990 under the guidance of Professor Allan S. Hoffman. In 1996, he joined the Department of Biological Sciences at KAIST, where he taught until his death. Professor Park was the recipient of numerous honors and awards during his academic career, which include the Clemson Award from the Society for Biomaterials and the Creative Knowledge Award, one of the highest awards bestowed by the Korean government. Professor Hoffman began his presentation by describing Professor Park as an outstanding and creative scientist. He reviewed Professor Park's pioneering and ground breaking research work at University of Washington on poly(N-isopropylacrylamide) hydrogels. He described the current need for smart polymer diagnostic assays, which are inexpensive, rapid, and portable assay systems to diagnose and report on contagious diseases that spread rapidly and create epidemic conditions in population centers throughout the world. He called these tests Point of Care assays, and explained that they were often carried out using microfluidic or paper dipstick assay formats. Professor Hoffman finished his speech with a summary of his own recent study outcomes and the contributions of Professor Park. Personally, I cannot forget Tae Gwan Park's enthusiastic academic guidance and amiability when I met him to discuss biomaterials for tissue regeneration and all of the participating well-known scientists, including Jeffrey Hubbell, Melody Swartz, Jackie Ying, Patrick Stayton, and Atsushi Maruyama highly estimated his warm personality as well as creative talent. Another of Professor Park's mentors, Robert S. Langer at the Massachusetts Institute of Technology, who could not join this meeting due to his schedule, sent a video talk and recalled that Professor Park was not only intelligent but also collaborative. Although Professor Park took his own life, we do not have to think of him as gone if we comprehend a quote from Alan Watts, a British philosopher. In his book, The Wisdom of Insecurity, he observes, 'Life and death are not two opposed forces; they are simply two ways of looking at the same force, for the movement of change is as much the builder as the destroyer.' Indeed, we owe our achievements in biomaterials research to him and live with him today.

Photorefractive recording of subwavelength-size binary data using near-field scanning optical microscopy

Seoul National UniversitySchool of Electrical EngineeringNational Research Laboratory of HolographyTechnologiesShinlim-Dong, Kwanak-GuSeoul 151-744, KoreaE-mail: byoungho@plaza.snu.ac.krAbstract. We propose a way of single-beam photorefractive recordingof subwavelength-size binary optical data using near-field scanning op-tical microscopy (NSOM). Data are recorded in the form of pure (withoutany change in the topography of the surface) refractive index changesinduced near the surface of photorefractive crystal by the light intensitydistribution from the subwavelength-size fiber tip of the NSOM. Thischange in the refractive index can modify the transmission characteris-tics of the NSOM. Therefore, the characteristics of the reading beamdepend on whether the light from the tapered fiber tip was previouslyexposed (recorded) or not, and thus can be regarded as on-off (binary)data.

Interlaboratory Precision and Bias in Metal Analysis at Industrial Hygiene Laboratories in Korea

Abstract A new quality control (QC) program for the Korean industrial hygiene laboratories was introduced in 1992. This study evaluated interlaboratory bias and precision in analyses of cadmium and lead in Korean industrial hygiene laboratories. There were significant interlaboratory differences in analytical values for both metals in two rounds of the Korean QC program. When the Korean QC program was first introduced, inter-laboratory precision and accuracy of data obtained from laboratories participating in the first round were extremely poor. There were several laboratories that consistently reported outliers. However, the accuracy and precision were significantly improved in the second round. The performance of one laboratory, the Seoul National University-School of Public Health Industrial Hygiene Laboratory, was improved by participating in the American Industrial Hygiene Association Proficiency Analytical Testing program, investigating the source of errors, and correcting the errors.
