Abstract Purpose Web-based learning tools are increasingly available for use and have been described in the pedagogical literature. However, rigorous comparisons between traditional learning methods and newer collaborative online tools have not been performed. Herein, we describe a web-based curriculum hosted on the collaborative Radiopaedia.org website. This curriculum was compared with traditional learning tools in a randomized, controlled fashion. Materials and Methods Medical students rotati...

A response is offered to an article by author Miguel A. Hernan on the causation of diseases, including casual inference. An overview of statistical approaches in public health research, including the use of statistical parameters and statistical association in health research, is provided.

Causal inference is a core task of science. However, authors and editors often refrain from explicitly acknowledging the causal goal of research projects; they refer to causal effect estimates as associational estimates.This commentary argues that using the term “causal” is necessary to improve the quality of observational research.Specifically, being explicit about the causal objective of a study reduces ambiguity in the scientific question, errors in the data analysis, and excesses in the inte...

Online education is no longer a trend, rather it is mainstream. In the Fall of 2012, 69.1% of chief academic leaders indicated online learning was critical to their long-term strategy and of the 20.6 million students enrolled in higher education, 6.7 million were enrolled in an online course (Allen & Seaman, 2013; United States Department of Education, 2013). The advent of online education and its rapid growth has forced academic institutions and faculty to question the current styles and techni...

Risk factor epidemiology has contributed to substantial public health success. In this essay, we argue, however, that the focus on risk factor epidemiology has led epidemiology to ever increasing focus on the estimation of precise causal effects of exposures on an outcome at the expense of engagement with the broader causal architecture that produces population health. To conduct an epidemiology of consequence, a systematic effort is needed to engage our science in a critical reflection both abo...

Objective. To compare performance and preferences of students who were randomly allocated to classroom or online sections of an elective course on immunization. Methods. Students were randomly assigned to either the classroom or online section. All course activities (lectures, quizzes, case discussions, vaccine administration, and final examination) were the same for both sections, except for the delivery of lecture material. Assessment. Students were surveyed on their preferences at the beginni...

Epidemiology is the study of the causes and distributions of diseases in human populations so that we may identify ways to prevent and control disease. Although this definition broadly serves us well, I suggest that in recent decades, our discipline’s robust interest in identifying causes has come at the expense of a more rigorous engagement with the second part of our vision for ourselves—the intent for us to intervene—and that this approach threatens to diminish our field’s relevance. I argue ...

Background: Distance learning may be useful for building health research capacity. However, evidence that it can improve knowledge and skills in health research, particularly in resource-poor settings, is limited. We compared the impact and acceptability of teaching two distinct content areas, Biostatistics and Research Ethics, through either on-line distance learning format or traditional on-site training, in a randomized study in India. Our objective was to determine whether on-line courses in...

Four quantitative meta-analyses examined whether teachers' expectations, referrals, positive and neutral speech, and negative speech differed toward ethnic minority students (i.e., African American, Asian American, and Latino/a) as compared with European American students. Teachers were found to hold the highest expectations for Asian American students (d = -.17). In addition, teachers held more positive expectations for European American students than for Latino/a (d = .46) or African American ...
