The Effectiveness of Technology-Enhanced Learning in Prosthodontic Education: A Systematic Review

OBJECTIVE

To compare the effectiveness of technology-enhanced learning (TEL) with traditional learning in prosthodontic education.

METHODS

The protocol was registered before commencement [CRD42023390277]. The search was conducted to identify randomized controlled trials (RCTs) focused on comparative assessment of TEL and traditional learning in prosthodontic education up to 6 June 2024. A comprehensive search strategy was formulated, encompassing multiple electronic databases. Screening, data extraction and risk of bias assessment using the Cochrane tool (RoB 2) were performed. Educational outcomes were evaluated by Kirkpatrick's four-level evaluation model.

RESULTS

Of 2830 records identified, 14 RCTs were included. All the trials were judged at high risk of bias or had some concerns. The included studies assessed the short-term benefits of various TEL approaches, including e-learning, blended learning, video demonstration specialized self-evaluation software and virtual reality simulation in prosthodontic education for undergraduates. Promising results were found in individual studies, particularly in terms of perceived learning conditions with problem-based learning (PBL) and self-reported understanding and confidence when using video demonstrations. Most studies reported comparable outcomes to traditional learning in practical skills assessments, while the results regarding the acquisition of theoretical knowledge through the incorporation of TEL approaches were contradictory. One study reported promising results in perceived learning conditions with the PBL approach, as well as improved self-reported understanding and confidence with the use of video demonstrations. Furthermore, there was a limited number of studies assessing the effect of TEL approaches on students' behaviour.

CONCLUSION

There is a lack of high-quality evidence to support the adoption of TEL approaches in prosthodontics. However, the incorporation of virtual reality simulation has demonstrated promising results, particularly in improving practical clinical skills.

The relationship of educational environment and preparedness to practice - perceptions of Malaysian dental graduates

Gauging dental graduates' perceptions of their university training and of how it prepares them for professional practice is useful in measuring the quality and adequacy of the curriculum to which they were exposed.

OBJECTIVES

This study aimed to evaluate the perceptions of dental graduates' educational environment as well as preparedness to practice, and how these two components are correlated.

METHODS

A self-administered, validated questionnaire, developed from previous studies, was distributed to dental graduates of a public Malaysian university (n = 178, response rate = 60%) via online and postal surveys. Bivariate analyses were carried out using Spearman's rank-order correlation (Spearman's Rho, significance level p < .01) to determine the correlation between (1) Global Preparedness Score and Global DREEM Score, (2) domains of DREEM Inventory and perceived preparedness, and (3) domains of perceived preparedness and DREEM Score.

RESULTS

The Global Preparedness Score was 191.52, with more than 90% of respondents feeling well prepared in the "General Patient Management," "Drug and Emergency Management" and "Practice Management" domains. The Global DREEM Score was 148.99/200, interpreted as "more positive than negative." The DREEM Inventory domains with the highest and lowest scores were "Students' Academic Self-Perception" (78.03%) and "Students' Social Self-Perception" (71.86%), respectively. A moderate positive correlation was found between Global Preparedness Score and Global DREEM Score (p < .01). In addition, moderate to large positive correlations were noted between perceived preparedness and "Student Perception of Learning," "Student Perception of Atmosphere" and "Student Academic Self-Perception" (p < .01). Moderate positive correlations were also found between the DREEM Score and most domains of perceived preparedness (p < .01).

CONCLUSIONS

The majority of graduates were well prepared to perform in most areas of clinical practice and perceived their overall educational environment as positive. In particular, those who viewed the educational environment in a positive light were also found to possess a good level of preparedness.
