Using Cognitive Load Theory to Improve Teaching in the Clinical Workplace.

ABSTRACT: Introduction:Cognitive load theory (CLT) views working memory as the primary bottleneck for learning, as it is limited in both capacity and retention. CLT delineates three types of activities that impose on working memory: intrinsic load, germane load, and extraneous load. These three constructs have practical ramifications for direct teaching, learning environments, and curricular design. CLT could help educators across health professions improve quality of teaching, especially in demanding and unpredictable workplace environments. However, few educational resources exist to familiarize clinical workplace educators with CLT. Methods:We developed a 2-hour workshop focused on CLT's core concepts and practical applications, targeted at health professions' workplace educators. It featured large-group, small-group, and individual reflective activities. An end-of-workshop survey was administered, and a follow-up survey was sent to participants 2 months after the workshop. Results:A total of 134 educators attended the first two offerings of the workshop in two different states. Participants considered CLT as relevant to a variety of workplace teaching settings and activities. Participants' self-assessed familiarity with CLT on a 0-100 scale increased from a mean of 36 (SD = 26) before the workshop to 59 (SD = 17) after the workshop. At follow-up, participants scored an average of 85% on content knowledge questions. Approximately half of respondents to the follow-up survey stated they had made or planned to make specific changes to their workplace teaching leveraging tenets of CLT. Discussion:The workshop conveyed CLT concepts and primed participants to independently craft CLT-based interventions for their own teaching practices.

Project description:Although there have been previous publications on curriculum innovations in teaching O&G to medical students, especially utilizing simulation-based education, there have been none, as far as we know, incorporating and evaluating the outcomes using cognitive load theory. The aim of this article was to describe the introduction, implementation, and evaluation of an innovative teaching program in O&G, incorporating simulation-based education, underpinned by cognitive load theory. Cognitive load is defined as the amount of information a working memory can hold at any one time and incorporates three types of cognitive load-intrinsic, extraneous, and germane. To optimize learning, educators are encouraged to manage intrinsic cognitive load, minimize extraneous cognitive load, and promote germane cognitive load. In these sessions, students were encouraged to prepare in advance of each session with recommended reading materials; to limit intrinsic cognitive load and promote germane cognitive load, faculty were advised ahead of each session to manage intrinsic cognitive load, an open-book MCQ practice session aimed to reduce anxiety, promote psychological safety, and minimize extraneous cognitive load. For the simulation sessions, the faculty initially demonstrated the role-play situation or clinical skill first, to manage intrinsic cognitive load and reduce extraneous cognitive load. The results of the evaluation showed that the students perceived that they invested relatively low mental effort in understanding the topics, theories, concepts, and definitions discussed during the sessions. There was a low extraneous cognitive load. Measures of germane cognitive load or self-perceived learning were high. The primary message is that we believe this teaching program is a model that other medical schools globally might want to consider adopting, to evaluate and justify innovations in the teaching of O&G to medical students. The secondary message is that evaluation of innovations to teaching and facilitation of learning using cognitive load theory is one way to contribute to the high-quality training of competent future healthcare workers required to provide the highest standard of care to women who are crucial to the overall health and wellbeing of a nation.

Project description:Allostatic load is commonly operationalized using a sum-score of high-risk biomarkers. However, this method implies that biomarkers contribute equally to allostatic load, as each is given equal weight. Our goal in this methodological paper is to evaluate this, and complementarily, to identify biomarkers that are most informative and least informative for developing an allostatic load index. Item response theory models provide an alternate approach to calculating the allostatic load score, by treating individual biomarkers (e.g. “items”) as indicators of a latent allostatic load construct. Item response theory scores account for the data-driven discriminating power of each biomarker, and an individual’s pattern of biomarker responses. To demonstrate feasibility of this approach, we used data from the 2015–2016 National Health Examination and Nutrition Survey (NHANES; N = 3751), with twelve allostatic load biomarkers representing immune response, metabolic function and cardiovascular health. Item response theory models revealed that body-mass-index and C-reactive protein were the most informative biomarkers for allostatic load. Both higher allostatic load sum-score and allostatic load item response theory score were associated with lower socio-economic status (p = 0.008; p<0.001, respectively). Further, both formulations of allostatic load were positively associated with a nine-item depression screener (p<0.001 for both), but only the item response theory score was also positively associated with the impact of depressive symptoms on daily life (p = 0.045). Item response theory scores may be more finely tuned to tease out effects, compared to sum-scores, and also provide more flexibility when there are missing biomarker measurements. Supplemental R code for our approach are included. Highlights • Methodological paper to introduce item response theory for calculating allostatic load.• Biomarker data from NHANES 2015–2016 representative of United States adults.• Body-mass-index and C-reactive protein most informative for allostatic load.• Item response theory captures more variability in allostatic load compared to sum-scores.• Future work - item response theory can standardize allostatic load across datasets.

Project description:BackgroundThe principle of workplace based assessment (WBA) is to assess trainees at work with feedback integrated into the program simultaneously. A student driven WBA model was introduced and perception evaluation of this teaching method was done subsequently by taking feedback from the faculty as well as the postgraduate trainees (PGs) of a residency program.MethodsDescriptive multimethod study was conducted. A WBA program was designed for PGs in Chemical Pathology on Moodle and forms utilized were case-based discussion (CBD), direct observation of practical skills (DOPS) and evaluation of clinical events (ECE). Consented assessors and PGs were trained on WBA through a workshop. Pretest and posttest to assess PGs knowledge before and after WBA were conducted. Every time a WBA form was filled, perception of PGs and assessors towards WBA, time taken to conduct single WBA and feedback were recorded. Faculty and PGs qualitative feedback on perception of WBA was taken via interviews. WBA tools data and qualitative feedback were used to evaluate the acceptability and feasibility of the new tools.ResultsSix eligible PGs and seventeen assessors participated in this study. A total of 79 CBDs (assessors n = 7 and PGs n = 6), 12 ECEs (assessors n = 6 and PGs n = 5), and 20 DOPS (assessors n = 6 and PGs n = 6) were documented. PGs average pretest score was 55.6%, which was improved to 96.4% in posttest; p value< 0.05. Scores of annual assessment before and after implementation of WBA also showed significant improvement, p value 0.039, Overall mean time taken to evaluate PG's was 12.6 ± 9.9 min and feedback time 9.2 ± 7.4 min. Mean WBA process satisfaction of assessors and PGs on Likert scale of 1 to 10 was 8 ± 1 and 8.3 ± 0.8 respectively.ConclusionBoth assessors and fellows were satisfied with introduction and implementation of WBA. It gave the fellows opportunity to interact with assessors more often and learn from their rich experience. Gain in knowledge of PGs was identified from the statistically significant improvement in PGs' assessment scores after WBA implementation.
