Our findings support the ICAP framework and provide practical implications for medical education, representing the fact that students learn more when they are involved in active learning activities, such as self-study and question generation, prior to discussions.

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

This 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.

The structure of the reconstructed Si(100) surface is studied using the tight-binding energy minimization method combined with a renormalization-group calculation. (2×1), c(2×2), p(2×2), (4×1), c(4×2), and p(4×2) structures are studied and compared. They are classified into two groups which are separated by a large activation barrier. In one group, (2×1), p(2×2), and c(4×2) structures are almost degenerate in energy, which can result in diffuse (2×1) LEED patterns. In the other group, a second-o

The value of dental students' self-assessment is often debated. The aim of this study was to explore whether reflective learning with feedback enabled dental students to more accurately assess their self-perceived levels of preparedness on dental competencies. Over 16 weeks, all third- and fourth-year students at a dental school in the Republic of Korea took part in clinical rotations that incorporated reflective learning and feedback. Following this educational intervention, they were asked to

Toyozawa's exciton self-trapping model for the Urbach tail is analyzed using scaling arguments. Following Halperin's analysis of the random impurity potential problem, we show that for the one-dimensional lattice the logarithm of the absorption coefficient scales as ${T}^{\ensuremath{-}\frac{2}{3}}$ or ${E}^{\frac{3}{2}}$. For the two- or three-dimensional lattice, spontaneous localization of excitons over a finite number of atomic sites with Gaussian potential fluctuations leads to Urbach behav

The aim of this study was to assess whether clinical reasoning and factual knowledge questions used in team-based learning (TBL) enhanced dental students' performance in esthetic dentistry. Ninety-seven third-year dental students enrolled in esthetic dentistry in a dental school in Korea in 2018 were assigned to 16 teams consisting of five or six students each. A four-step TBL sequence (pre-study, readiness assurance test, appeal/feedback, and final test) was designed to examine how clinical rea

After performing an analysis of the anomalous concentration and temperature dependence of absorption tails in GexSe1-x and AsxSe1-x systems, the author proposes that these glasses retain locally layered structures at particular stoichiometries corresponding to GeSe2 and As2Se3, and that a reversible structural change is taking place well below the glass transition temperature. A phenomenological model of layer buckling is presented to explain the slope of the exponential tail in the optical abso

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

The purpose of this study was to summarize the associations of physical activity (PA) and sedentary time (SED) with metabolic health and examine the effects of time reallocation on metabolic health in adolescents using accelerometer data. A literature search was conducted using PubMed, ScienceDirect, Web of Science, Cochran Library, and Google Scholar, and 27 articles were reviewed. Recent research generally confirms the associations of PA and SED with metabolic health. High PA levels and low SE

Motor learning is often hindered or facilitated by visual information from one's body and its movement. However, it is unclear whether visual representation of the body itself facilitates motor learning. Thus, we tested the effects of virtual body-representation on motor learning through a virtual reality rotary pursuit task. In the task, visual feedback on participants' movements was identical, but virtual body-representation differed by dividing the experimental conditions into three condition

Purpose The purpose of this study was to evaluate the moderate to vigorous physical activity(MVPA) and sedentary time measured by accelerometer. Furthermore, the level of physical activity and adherence rate of physical activity guideline(PAG) were compared with the self-reported questionnaire. Methods The MVPA, sedentary time, and adherence rate of PAG according to age and sex were examined to people who agreed to wear accelerometers among the participants of the 2014-2015 Korea National Health
