Comparison of Active Learning Techniques: Audience Response Questions Versus Small Group Discussion on Immediate- and Long-term Knowledge Gain.

ABSTRACT:

Objectives

Active learning techniques help with motivation, involvement, and retention during didactics. There are few studies comparing different active learning methods, and these have yielded mixed results. The objective of this study was to compare the effect of two active learning methods-small-group discussion and audience response system (ARS)-on immediate- and long-term knowledge gain.

Methods

This was a prospective experimental study of emergency medicine (EM) subinterns and residents. Participants were randomized into two groups, and baseline knowledge was assessed with a multiple-choice pretest. Didactic sessions on salicylate toxicity and ocular trauma were given to both groups utilizing either small-group discussion or ARS. A crossover design was utilized to ensure that both groups received instruction by each method. A multiple-choice posttest was administered following the didactics and again 2 months later. Pre- and posttests were identical. All test items were written by an academic faculty member with advanced training in medical education and item writing and were based on the goals and objectives of the session. Test items were piloted with a reference group of learners. Didactic instructors were blinded to test items. Data were analyzed using a linear mixed-effects model.

Results

Thirty-eight subinterns and residents participated in the study. Both instructional methods showed immediate- and long-term knowledge gain. The linear mixed-effects model did not demonstrate any significant difference between instructional methods on immediate knowledge gain (mean difference = 0.18, p = 0.62, 95% confidence interval [CI] = -0.52 to 0.88) or long-term knowledge gain (mean difference = -0.42, p = 0.36, 95% CI = -1.32 to 0.47).

Conclusion

In this small study, there was no significant difference between instructional methods on immediate- and long-term knowledge gain in EM subinterns and residents.

Project description:Failed user authentication is a common event. Forgotten passwords and fingerprint non-recognition are the most common causes. Therefore, there is a need for efficient backup authentication methods, known as fallback authentication. However, fallback authentication methods suffer from different security and usability issues. This study aims to improve the security and usability of knowledge-based fallback authentication in the form of static security questions. The approach proposed in this study was designed considering different factors, such as question features, authentication mechanisms, and the use of tools to aid in composing memorable and secure answers. This study used a two-part experiment with 23 participants to evaluate the proposed approach based on security model testing. The results show that the proposed approach offered improved resistance to blind guess, focused guess, and observation guess attacks. While usability was clearly improved with questions that were based on recognition mechanisms, our results indicate that fallback authentication systems need a flexible level of security and avoidance of complexity in composing answers. In addition, our results indicate the effectiveness of using user behavioral details in the choice of topics for questions, where behavioral questions must have both high recall levels and resistance against guessing attacks. This work theoretically extends the knowledge of fallback authentication research by evaluating new security questions for fallback authentication considering replace of classical topics of security questions by introducing new topics of security questions based on user behavior and personal preferences. Also, this study applies methods of managing answers to security questions by encouraging users to compose answers based on free strict rules that inspire them to create strong and memorable answers based on their own rules. In addition, the findings of this study could support the deployment of knowledge-based authentication in fallback systems as a practical contribution to the user authentication field.
