Effective Feedback Strategy for Formative Assessment in an Integrated Medical Neuroscience Course

Purpose

Despite the different benefits of formative assessments in an integrated medical curriculum, the effective strategies to provide feedback to medical students to benefit from the different merits of formative assessment are not fully understood. This study aims to determine the effect of different strategies of formative feedback on students' outcomes in a medical neuroscience course.

Method

We compared medical students' performance in summative examinations in the academic year that formative feedback was provided using in-person discussion and compared such performances with the academic year when the feedback was provided by written rationales or a combination of written rationales and in-person discussion. We also surveyed medical students' preferences for whether written or in-person formative feedback is a better strategy to provide feedback at the end of each course.

Results

ANOVA found a significant difference in summative performance scores for those scoring ≥ 70% when formative feedback was provided by providing a rationale, in-person, and a combination of both ([F (2,80) = 247.60, P < 0.001]. Post hoc analysis revealed a significant and highest performance when feedback was provided using the written rationale approach (***P < 0.05), followed by in-person (**P < 0.05). In contrast, the least performance was recorded when formative feedback was provided using a combination of providing a written rationale for the answers to the questions and in-person discussion of the questions (*P < 0.05). Students' preferred approach for receiving formative feedback for their formative assessment was highest for written rationale (***P < 0.05), followed by in-person or a combination of in-person and written rationale (**P < 0.05).

Conclusion

Our results found that medical students preferred a written formative feedback approach, which was associated with better student performance on the summative examination. This study reveals the importance of developing effective strategies to provide formative feedback to medical students for medical students to fully benefit from the merits of formative assessment in an integrated medical school curriculum.

Preparedness of medical students to provide nutrition care following a nutrition education intervention

BACKGROUND

Globally, 71% of deaths are due to non-communicable diseases (NCDs) of which 77% of these deaths occur in low-and-middle income countries. Nutrition is an important contributor to the occurrence, progression and management NCDs. Health care professionals' promotion of the adoption of healthy dietary habits among individuals has been shown to reduce the occurrence of NCDs. We assessed the effects of a nutrition education intervention on medical students' self-perceived preparedness to provide nutrition care.

METHODS

We administered a pre, post and four-weeks follow-up questionnaire to second year medical students who participated in a nutrition education intervention that adapted varied teaching and learning activities. Outcomes were self-perceived preparedness, relevance of nutrition education and perceived need for further training in nutrition. Repeated measures and Friedman tests were used to assess differences in mean scores across pre, post and 4-weeks follow up assessment based on p < 0.5 at 95% confidence interval.

RESULTS

The proportion of participants who felt prepared to provide nutrition care increased significantly (p = 0.001) from 38% (n = 35) at baseline to 65.2% (n = 60) immediately post-intervention and to 63.2% (n = 54) at 4-weeks follow-up. At baseline, 74.2% (n = 69) of the students perceived nutrition education to be relevant to their future career as medical doctors which increased to 85% (n = 78) immediately after the intervention (p = 0.026) and to 76% (n = 70) 4-weeks follow-up. The proportion of participants who reportedly said they will benefit from further training in nutrition increased from 63.8% (n = 58) at pre-intervention to 74.0% (n = 68) at post-intervention (p = 0.016).

CONCLUSION

An innovative, multiple-strategy nutrition education intervention can improve medical students' self-perceived preparedness to provide nutrition care.

Nutrition education intervention improves medical students' dietary habits and their competency and self-efficacy in providing nutrition care: A pre, post and follow-up quasi-experimental study

Objective

Most doctors and medical students report inadequate competencies in nutrition care. We evaluated the impact of a nutrition education intervention on medical students' lifestyle habits, dietary diversity, nutrition care knowledge, attitude toward nutrition care, and their level of self-efficacy in the provision of nutrition care.

Methods

All 2nd-year medical students were enrolled into a 5 week, 24-h nutrition education intervention that involved both deductive and practical sessions. Pre-, post and 4 weeks follow-up assessments were conducted.

Results

At post- and 4-weeks post-intervention the number of days participants consumed vegetables and engaged in moderate-to-vigorous physical activity significantly (p = 0.003 and 0.002) improved respectively from baseline. Mean nutrition care knowledge scores of participants increased by 3.27 points (95% Cl: 1.98-4.56, p < 0.001) from 19.49 at baseline through to 24.78 post- and 22.76 4 weeks follow-up. No significant [X ( 2 ) 2 = 1.568, p = 0.457] change in mean attitude toward nutrition care score was recorded. Mean level of self-efficacy in the provision of nutrition care improved significantly by 1.73 (95% Cl: 1.17-2.28, p < 0.001) at post-intervention and 4 weeks follow-up compared to the baseline scores.

Conclusion

The intervention improved the nutrition care knowledge, self-efficacy in the provision of nutrition care as well as medical students' own consumption of vegetables, dietary diversity and their engagement in moderate-to-vigorous physical activity. However, continuous implementation of nutrition education interventions is needed to sustain these outcomes and further improve the nutrition education experience of medical students.

A scoping review of nutrition education interventions to improve competencies, lifestyle and dietary habits of medical students and residents

We reviewed the available research and gave an overview of the effects of nutrition education interventions (NEIs) on medical students’ and residents’ knowledge of nutrition, attitudes towards nutrition care, self-efficacy, dietary practices and readiness to offer nutrition care. From 28 May through 29 June 2021, we searched Google Scholar, PubMed, ProQuest, Cochrane and ProQuest to retrieve 1807 articles. After conducting de-duplication and applying the eligibility criteria and reviewing the title and abstract, 23 papers were included. The data were descriptively and narratively synthesised, and the results were displayed as frequencies, tables and figures. Twenty-one interventions were designed to increase participants’ knowledge of nutrition-related topics, and eighteen studies found that nutrition knowledge had significantly improved post-intervention. Only four of the eleven studies that reported on attitudes about nutrition post-intervention showed a meaningful improvement. The self-efficacy of participants was examined in more than half of the included studies (n 13, 56⋅5 %), and eleven of these studies found a significant increase in the participants’ level of self-efficacy to offer nutrition care post-intervention. At the post-intervention point, seven interventions found that dietary and lifestyle habits had significantly improved. The review demonstrated the potential of NEIs to enhance participants’ dietary habits and nutrition-related knowledge, attitudes and self-efficacy. Reduced nutrition knowledge, attitude and self-efficacy scores during the follow-up, point to the need for more opportunities for medical students and residents to learn about nutrition after the intervention.

Improving Nutrition Education with Second-Year Medical Students: From Take-Home Assignment to Large-Group Application Exercise

Augmenting its nutrition education, the Herbert Wertheim College of Medicine Endocrinology course initially used a case-based, take-home assignment on type II diabetes dietary guidelines, with literature search requirement and a module on relevant social determinants of health (SDOH). Course evaluations indicated this assignment did not adequately improve student perceptions of learning. For the subsequent cohort, we changed to a large-group active learning session, requiring one faculty facilitator, where student teams created problem lists including SDOH and reviewed research articles to support evidence-based nutrition recommendations. Survey results indicate that the new session resulted in significantly improved student perceptions of learning.

The state of nutrition in medical education in the United States

Despite the significant impact diet has on health, there is minimal nutrition training for medical students. This review summarizes published nutrition learning experiences in US medical schools and makes recommendations accordingly. Of 902 articles, 29 met inclusion criteria, describing 30 learning experiences. Nutrition learning experiences were described as integrated curricula or courses (n = 10, 33%), sessions (n = 17, 57%), or electives (n = 3, 10%). There was heterogeneity in the teaching and assessment methods utilized. The most common was lecture (n = 21, 70%), often assessed through pre- and/or postsurveys (n = 19, 79%). Six studies (26%) provided experience outcomes through objective measures, such as exam or standardized patient experience scores, after the nutrition learning experience. This review revealed sparse and inconsistent data on nutrition learning experiences. However, based on the extant literature, medical schools should build formal nutrition objectives, identify faculty and physician leadership in nutrition education, utilize preexisting resources, and create nutrition learning experiences that can be applied to clinical practice.

Nutrition Education on the Wards: A Self-Study Module for Improving Medical Student Knowledge of Nutrition Assessment and Interventions

INTRODUCTION

Nutrition plays a key role in the prevention and treatment of disease. Hospitalized patients are often malnourished, which is a major contributor to medical complications, decreased quality of life, lengthened medical stay, increased health care costs, and mortality. However, medical students continue to have inadequate education in nutrition and report feeling poorly trained in nutrition. We proposed an online module that could be used by medical students as a self-study activity to learn about key signs for the diagnosis of malnutrition and the nutrition interventions available in the hospital setting.

METHODS

Third- and fourth-year medical students at Rutgers Robert Wood Johnson Medical School in medicine, surgery, and critical care clerkships were given access to an online nutrition education module discussing the signs of malnutrition in hospitalized patients and the interventions available in the inpatient setting. A premodule and postmodule survey was given via email at the beginning and at the end of the clerkship. A one-sample t test was used to assess the relationship between the mean scores of the pre- and postmodule surveys.

RESULTS

One hundred nine out of 255 students responded to the premodule survey. Thirty-two students completed the module and postmodule survey. There was a significant difference in mean scores between students who completed the module and postmodule survey compared to the overall student population prior to having access to the module.

DISCUSSION

Medical students have limited training in nutrition education, and our findings show that a self-study online module can improve students' knowledge.

Proceedings of the inaugural International Summit for Medical Nutrition Education and Research

Medical Nutrition Education (MNE) has been identified as an area with potential public health impact. Despite countries having distinctive education systems, barriers and facilitators to effective MNE are consistent across borders, demanding a common platform to initiate global programmes. A shared approach to supporting greater MNE is ideal to support countries to work together. In an effort to initiate this process, the Need for Nutrition Education/Innovation Programme group, in association with their strategic partners, hosted the inaugural International Summit on Medical Nutrition Education and Research on August 8, 2015 in Cambridge, UK. Speakers from the UK, the USA, Canada, Australia, New Zealand, Italy, and India provided insights into their respective countries including their education systems, inherent challenges, and potential solutions across two main themes: (1) Medical Nutrition Education, focused on best practice examples in competencies and assessment; and (2) Medical Nutrition Research, discussing how to translate nutrition research into education opportunities. The Summit identified shared needs across regions, showcased examples of transferrable strategies and identified opportunities for collaboration in nutrition education for healthcare (including medical) professionals. These proceedings highlight the key messages presented at the Summit and showcase opportunities for working together towards a common goal of improvement in MNE to improve public health at large.
