On a now orthodox view, humans and many other animals areendowed with a “number sense”, or approximate number system(ANS), that represents number. Recently, this orthodox view hasbeen subject to numerous critiques, with critics maintaining eitherthat numerical content is absent altogether, or else that someprimitive analog of number (‘numerosity’) is represented as opposedto number itself. We distinguish three arguments for these claims –the arguments from congruency, confounds, and imprecision – andshow that none succeed. We then highlight positive reasons forthinking that the ANS genuinely represents numbers. The upshot isthat proponents of the orthodox view should not feel troubled byrecent critiques of their position.

Visual number adaption is a widely accepted phenomenon. This paper advances an alternative explanation for putative cases of the phenomenon. We propose that such cases may simply reflect observers adapting to the items in perceived displays, rather than their numerical quantity. Three experiments motivate consideration of this novel proposal and call into question the evidential basis for received formulations of the number adaptation hypothesis.

Background

Pediatric emergency medicine (PEM) has seen little progression toward a standardized PEM educational framework. The 2018 Academic Emergency Medicine Consensus Conference on Advancing PEM Education addressed this gap in core EM education. Absent elements include a "broad needs assessment to identify and evaluate existing curricula and systems gaps in EM training" and a "clearly defined core PEM curriculum that unifies and drives the learning process." PEM education innovators were called to construct a "unified foundation in PEM education for all levels of emergency care" and to "promote innovation in teaching and learning strategies in curricula." We endeavored to meet this challenge at our institution.

Methods

The PEM curriculum design is based on the Kern model of curriculum development and included a needs assessment, development of goals and objectives, educational strategies, implementation, evaluation, and programmatic feedback. We committed to using effective learning strategies and active learning methods in developing our curriculum and conducted a 1-year pilot within our EM residency's didactic conference. We used exit surveys to collect feedback for each session as well as midyear focus groups to gauge the program's effectiveness. At the start and end of the pilot year residents completed the PEM survey regarding the effect of the PEM curriculum on their self-assessed knowledge, training, and comfort in managing PEM topics.

Results

Feedback regarding the PEM curriculum was positive. Following 1 year of the pilot curriculum, learners in the PGY-1 and PGY-3 classes demonstrated statistically significant improvement in their self-assessed knowledge, training, and comfort with PEM topics. The PGY-2 class had a similar statistically significant improvement in self-assessed knowledge in PEM topics.

Conclusions

Our novel PEM curriculum was well received and has shown early evidence of improving self-assessed knowledge and comfort among EM residents.

A working group at the 2012 Academic Emergency Medicine consensus conference on education research in emergency medicine (EM) convened to develop a curriculum for dedicated postgraduate fellowships in EM education scholarship. This fellowship is intended to create future education scholars, equipped with the skills to thrive in academic careers. This proceedings article reports on the consensus of a breakout session subgroup tasked with defining a common core content for education scholarship fellowships. The authors propose that the core content of an EM education scholarship fellowship can be categorized in four distinct areas: career development, theories of learning and teaching methods, education research methods, and educational program administration. This core content can be incorporated into curricula for education scholarship fellowships in EM or other fields and can also be adapted for use in general medical education fellowships.
