"Job shadowing for early undergraduate dental students: Validation of educational effectiveness using structural equation modeling","Job shadowing for early undergraduate dental students: Validation of educational effectiveness using structural equation modeling","Susumu Abe, Yoshizo Matsuka, Ayu Murakami, Omar Maningo Rodis, Kenji Oka, Toshinori Okawa, Chie Wada -Mihara, Chihiro Shinohara, Fumiaki Kawano","Susumu Abe, Yoshizo Matsuka, Ayu Murakami, Omar Maningo Rodis, Kenji Oka, Toshinori Okawa, Chie Wada -Mihara, Chihiro Shinohara, Fumiaki Kawano","null","This study aimed to evaluate and validate the educational effectiveness of a job shadowing class as a dental teaching programme for preclinical dental students through a questionnaire that assessed related student perceptions. A total of 124 preclinical (second year) dental students at Tokushima University participated in job shadowing placements from 2017 to 2019. Each student observed dental practice or surgery for 1 day in the university hospital. After shadowing, the students were requested to fill out a nine-item questionnaire based on a five-point scale. The first analysis was performed to calculate the correlation for each item. Furthermore, regression analysis for the categorical data was performed to show the relationship between eight questions (Items 1-8) and one question (Item 9: comprehensive evaluation). Next, factor analysis was performed to determine students' perceptions regarding the shadowing class. Ninety-eight students (response rate: 79%) completed the questionnaire. There was a strong relationship amongst Items 1, 8 and 9 (""interested in dentistry as a job,"" ""learning motivation"" and ""comprehensive evaluation"" respectively) based on the results of the correlation and regression analysis. The factor analysis led to three student perceptions as latent factors, namely, ""Interesting,"" ""Self-awareness"" and ""Future Goal,"" which had a relatively close inter-factor correlation (0.465-0.772). The finding suggests that job shadowing may increase a students' interest in a dentistry career at an early stage of their education and learning motivation, along with generating self-awareness. This programme may present possible educational effectiveness in dental education.","This study aimed to evaluate and validate the educational effectiveness of a job shadowing class as a dental teaching programme for preclinical dental students through a questionnaire that assessed related student perceptions.

There are several methods of active learning, including flipped classroom (FC) and team-based learning (TBL). In FC, students are required to study before classes. In TBL, students also study before class, take individual readiness assurance test (iRAT) and team readiness assurance test (tRAT), then discuss group assignment projects (GAPs) during class. The purpose of this study was to compare the effectiveness between FC and TBL.
The effectiveness of FC and TBL was assessed from the results of the term-end examinations, questionnaires and practice examinations. To check the difficulty of the term-end examinations, control dentists took the same examinations and we calculated the equating score with item response theory.
Statistical analysis showed that the correct answer rate in term-end examinations was significantly different in comparison with the time of the trial, and for the participants (students and dentists). The term-end examination score of FC and TBL did not show a statistical difference. The student questionnaire showed that TBL had higher scores than FC on various factors such as student positive attitude, preparation, ingenuity of teacher and achieving the class goals. The crown & bridge score from the practice examination of 6th-year students who had FC + TBL were constantly higher than the Japanese national average score. The identification index of FC and TBL did not show the statistical difference and there was no statistical difference on item response theory between FC and TBL.","Active learning is a concept that allows students to study and learn actively by themselves to get knowledge.

With globalized education, professions are becoming very competitive, embracing student-centeredness compelling them to introduce active learning activities. A study funded by Japan's Ministry of Education conducted a needs analysis, proposed a solution, and implemented an active learning approach. Since the latter is still new in the Japanese teaching-learning environment, this current study aimed at assessing the willingness of undergraduate students of dental medicine to participate in active learning activities rather than the typical passive-style teaching-learning educational process. Three active implementation-learning activities, namely International Group Discussions (IGD), Student-Teacher Experience (STE) and Role Play Activities (RPA) were included in the Dental English course in a classroom setting at a dental school in Japan. Students had to choose between participating in the activity or taking the final examination. Two hundred and three third-year undergraduate dental students participated over a 5-year period from October 2013 to March 2017. For IGD, the researchers assigned students to a topic and grouped them with visiting international exchange students. For STE, researchers gave students teacher-prepared presentation slides on basic dental topics, which they presented in front of their classmates. For RPA, students had to do prepared role-play and impromptu role play. Peer and teacher feedbacks of the activities were given to all students. At the end of the course, the students evaluated the active learning activities and wrote their comments in a free entry survey. All 203 students participated in the active learning activities confirming the changing learning needs of Japanese students in this dental school. The most common comment was that the class was interesting, fun, an easy-to-understand way to learn dental terms, and a safe way to express themselves in the English language. The majority of Japanese students preferred the active learning style. The study revealed that students reported greater engagement and better learning with proper guidance and time to prepare for the activities.","Education in Japan and other Asian countries advocates the stereotypical passive learning style where students are limited in their breadth of knowledge dismissing anything not imparted by their teachers.

The participants were 10 male undergraduate dental students who had finished clinical training in the university hospital 1 year before this study started. They performed a crown preparation on an upper pre-molar tooth using SIMROID and CLINSIM as the practical clinical trials. The elapsed time for preparation was recorded. The taper of the abutment teeth was measured using a 3-dimensional shape-measuring device after this trial. In addition, a self-reported questionnaire was collected that included physical pain, treatment safety and maintaining a clean area for each simulator. Qualitative data analysis of a free format report about SIMROID was performed using text mining analysis. This trial was performed twice at 1-month intervals. The students considered physical pain, treatment safety and a clean area for SIMROID significantly better than that for CLINSIM (P < .01). The elapsed time of preparation in the second practical clinical trial was significantly lower than in the first for SIMROID and CLINSIM (P < .01). However, there were no significant differences between the abutment tapers for both systems. For the text mining analysis, most of the students wrote that SIMROID was similar to real patients.

The results of this study suggest that TBL-style lecture was more effective than traditional-style lecture for teaching fixed prosthodontics and that TBL was a more efficient mode of delivering dental education than traditional lecture-based teaching.","null","null","2015-04","Journal of Dental Education","Journal of Dental Education","Vol.79","No.4","417","423","eng","true","null","scientific_journal","null","null","null","1930-7837","null","null","null","null","null"

Thirty-two applicants to the training programme and 35 experienced SPs were included in this study. The experienced SPs served as a reference group. The rate of accurate responses and the rate of appropriate feedback were assessed with pre- and post-training tests, and these two outcome measures were compared with those of the experienced SPs. No significant differences were found in trainee response accuracy or appropriateness of feedback between pre- and post-training tests. The response accuracy rate of the trainees on the pre-training test was significantly lower than that of SPs with 1-2 years of experience, whilst there was no significant difference between these SPs and the trainees on the post-training test.

The perception levels and anxiety levels during the experiment period were examined using Time series Visual Analog Scale (T-VAS) and state-trait anxiety inventory-form (STAI) respectively. The nasal skin temperature was measured with thermography every 5 minutes. As a result, when levels of pain and anxiety increased by the ice stimulation, the nasal skin surface temperature decreased. On the other hand, when the pain and anxiety were taken away after the ice stimulation was stopped, the nasal skin temperature increased and reached the same temperature as before the stimulation. These results suggest strongly that the psychological state of pain and anxiety could be predicted by the measurement of nasal skin temperature.","null","null","2008-12-25","小児歯科学雑誌","The Japanese Journal of Pediatric Dentistry","Vol.46","No.5","578","584","null","true","null","scientific_journal","null","null","10.11411/jspd1963.46.5_578","0583-1199","null","https://ci.nii.ac.jp/naid/10027487261/","null","null","null"
