Evaluating the use of HEIghten critical thinking assessment to monitor critical thinking in dental students

PURPOSE/OBJECTIVES

Critical thinking and evidence-based dentistry are skills that dental students are required to demonstrate, but monitoring and quantifying progress can be challenging. This study is investigating whether the HEIghten critical thinking assessment (HCTA) could be used as a potential tool, both for use prior to admitting students, and to monitor whether the students' skills improve over their time at dental school.

METHODS

Freshman dental students (n = 92) were given the HCTA during their first semester of dental school. Statistical analyses were then performed to examine the association of Dental Admission Test (DAT) scores (overall, perceptual ability, and total science) and Grade Point Average (GPA) (overall and science) on critical thinking scores (total, analytic, and synthetic).

RESULTS

There was a significant positive association between GPA, DAT scores and critical thinking scores.

CONCLUSIONS

Our results indicate that the HCTA may be a useful tool to enable monitoring of students analytical and synthetic skills throughout their time at dental school.

Critical Thinking: A Program Review of Doctor of Audiology Students

PURPOSE

Critical thinking is a crucial component of health care, and its importance has been recognized in training medical professionals. This study reports critical thinking skills for entering doctor of audiology (AuD) students and the trajectory of the change in critical thinking skills measured 2 times over a period of 3 years.

METHOD

This longitudinal, descriptive, and exploratory design was implemented for programmatic review. Critical thinking skills were measured using the Health Sciences Reasoning Test (HSRT; Insight Assessment) upon entering the program and compared to measurements during the final month of academic coursework. Descriptive statistics, exploratory analyses of the HSRT scores among cohorts, the relationship of the HSRT to the graduate record examinations (GREs), and changes in the HSRT over time using a repeated measures multivariate analysis of variance were conducted.

RESULTS

There were no significant differences in critical thinking skills between any of the cohort years. There was a significant correlation between the GRE verbal scores and OVERALL HSRT. Improvements in critical thinking skills were found between the time the students entered the graduate program and their final academic semester. Greater gains were reported for students who initially scored below the 50th percentile on the OVERALL HSRT.

CONCLUSIONS

This program review showed improvement in the critical thinking skills of AuD students during their academic training program. Information regarding critical thinking skills may be useful for programs to monitor students' clinical thinking skills and possibly include clinical and didactical activities to promote critical thinking skills.

Change in students' critical thinking over the course of dental education

PURPOSE

The purpose of this study was to test whether critical thinking changes over the course of dental education by assessing dental students at the beginning and toward the end of their training.

METHODS

Dental student participants completed a survey at the beginning of their first year (August 2019) and at the start of their last year of dental school (August 2022). The survey consisted of two instruments designed to measure the disposition and metacognition components of critical thinking. The study used a pretest-posttest design. Paired t tests were used to determine whether critical thinking scores changed over the 3-year period.

RESULTS

Surveys were completed by 85 of 94 students (90%) on the pretest and 63 of 93 students (68%) on the posttest. Of the 92 students who were members of the class at both testing periods, data were available for 59 students (64%). There were significant mean decreases in disposition and its tolerance for cognitive complexity subscale, as well as in metacognition and its metacognitive strategies subscale (p < .05). There was no significant mean change in either open-mindedness or metacognitive thinking.

CONCLUSION

Results of this study suggest that some aspects of critical thinking (metacognition and disposition) decrease over the course of dental education. Future research should investigate why this is the case, and explore different instructional methods designed to improve critical thinking.

Critical thinking education for dental schools in Asia: Perceptions of educators

Teaching competence in critical thinking is an important element of undergraduate dental curricula. The pedagogy for critical thinking education in Asia requires further discussion and neither the current situation nor the possible challenges are widely known from the perspectives of dental educators. Therefore, seven educators from four countries gathered online in the summer of 2021 to share the current situation and possible challenges. All the participants considered "critical thinking" was "important" (43%) or "very important" (57%), however, 86% mentioned that they faced challenges in delivering education in critical thinking. The challenges to delivering critical thinking education were insufficient time in the curriculum and lack of human resources; lack of information on appropriate teaching methods for the student population; and no established methods of assessment. How to teach and assess critical thinking therefore requires more brainstorming, and raising the awareness of educators to implement this education might be necessary.

Effectiveness of an E-module at teaching novice learners critical thinking skills related to dentistry

BACKGROUND

Technological advances and pedagogical shifts toward active learning have led dental academics to explore alternatives to traditional didactic lectures, yet questions remain regarding the effectiveness of new modalities at both relaying foundational knowledge and inspiring critical thinking. Here, we developed an integrative e-learning module on the subject of bone growth and recruited novice learners from undergraduate institutions to participate. The aim of the study was to investigate the impact of learning modality on novice learners' ability to apply newly acquired knowledge to critical thinking exercises related to dentistry.

METHODS

In the fall of 2019, 42 undergraduate students from University of Nebraska and Nebraska Wesleyan University campuses voluntarily participated in the study involving a pretest, intervention, posttest, and retention test with survey and results were analyzed.

RESULTS

Our data reveal a significant difference in mean pre- and posttest scores within delivery group of both traditional lecture and e-module cohorts (p < 0.0001) and no statistically significant difference between cohorts in posttest scores. Similarly, there was no significant difference in student performance on higher-level cognitive skill questions between cohorts, indicating that students learning via e-module were able to apply foundational knowledge to clinical scenarios similarly to students learning via content-expert lecture discussions.

CONCLUSION

The authors shed light on an opportunity to integrate e-learning into dental education, relieving time constraints for faculty and meeting the needs of our tech-savvy students, without compromising the fostering of critical thinking skills in future dentists.

A nationwide survey assessing the satisfaction of dental colleges graduates with their undergraduate experience in Saudi Arabia

OBJECTIVE

To date, there are no publications on the Saudi graduates' perceived value of their dental curriculum. The aim of this nation-wide survey was to investigate graduates' satisfaction with specific disciplines of their dental education and training. The first part of this study addressed findings according to the respondents' gender and the number of years of postgraduate experience (Graduate-related factors).

METHODS

An electronic questionnaire was emailed to registrants of the Saudi Dental Society, specifically dental interns, general dentists, and specialized dentists who graduated from private and governmental dental colleges in Saudi Arabia (n = 2185).

RESULTS

The response rate was 36.4 %. The number of male respondents was (n = 352, 44.2 %), the remainder being female (n = 444, 55.8 %). The number of recent dentists (≤ 5 years since graduation) was (n = 428, 53.8 %) and experienced dentists (n = 368, 46.2 %). There were statistically significant gender variations in satisfaction levels, and among dentists with different post-graduation experiences. Although male and female dental students are taught similar curriculums and have similar graduation requirements, there were statistically significant differences in various subjects covered. Similarly, recent and experienced dentists reported statistically significant differences in satisfaction in various subjects.

CONCLUSION

This study provides graduates' perspectives on the strengths and weaknesses of their dental education in Saudi Arabia. The findings help in curriculum reform and collaborations between the dental colleges nationally. Ultimately this can lead to formulating a national dental accreditation and assessment body.

CLINICAL SIGNIFICANCE

The findings of this study provide graduates' perspective on the dental education received in Saudi Arabia. This will help stimulate discussion and collaboration within and amongst the colleges on improving their curriculum in this fast-paced, evolving field of dentistry.
