Our results suggest preparing to teach and actively teaching may have independent positive effects on peer teacher learning outcomes.

Two groups of adolescents with a childhood history of language impairment were compared with a group of developmentally dyslexic young people of the same age and nonverbal ability. The study also included two comparison groups of typically developing children, one of the same age as those in the clinical groups, and a younger comparison group of similar reading level to the dyslexic students. Tests of spoken and written language skills revealed that the adolescents with dyslexia were indistinguishable from those with resolved language impairments on spoken language tasks, and both groups performed at age-expected levels. However, both dyslexic readers and those with resolved specific language impairments showed deficits in phonological awareness. On written language tasks, a different pattern of performance was apparent. In reading and spelling, adolescents with dyslexia performed only as well as those with persistent oral language impairments and younger controls. However, their reading comprehension was better. The theoretical and educational implications of these findings are discussed.

Objective: Residents must become proficient in a variety of procedures. The practice of learning procedural skills on patients has come under ethical scrutiny, giving rise to the concept of simulation-based medical education. Resident training in a simulated environment allows skill acquisition without compromising patient safety. We assessed the impact of a simulation-based procedural skills training course on residents' competence in the performance of critical resuscitation procedures. Methods: We solicited self-assessments of the knowledge and clinical skills required to perform resuscitation procedures from a cross-sectional multidisciplinary sample of 28 resident study participants. Participants were then exposed to an intensive 8-hour simulation-based training program, and asked to repeat the self-assessment questionnaires on completion of the course, and again 3 months later. We assessed the validity of the self-assessment questionnaire by evaluating participants' skills acquisition through an Objective Structured Clinical Examination station. Results: We found statistically significant improvements in participants' ratings of both knowledge and clinical skills during the 3 self-assessment periods (p < 0.001). The participants' year of postgraduate training influenced their self-assessment of knowledge (F 2,25 = 4.91, p < 0.01) and clinical skills (F 2,25 = 10.89, p < 0.001). At the 3-month follow-up, junior-level residents showed consistent improvement from their baseline scores, but had regressed from their posttraining measures. Senior-level residents continued to show further increases in their assessments of both clinical skills and knowledge beyond the simulation-based training course. Conclusion: Significant improvement in self-assessed theoretical knowledge and procedural skill competence for residents can be achieved through participation in a simulation-based resuscitation course. Gains in perceived competence appear to be stable over time, with senior learners gaining further confidence at the 3-month follow-up. Our findings support the benefits of simulation-based training for residents.

In 2015, the Medical College Admission Test (MCAT) was redesigned to better assess the concepts and reasoning skills students need to be ready for the medical school curriculum. During the new exam’s design and rollout, careful attention was paid to the opportunities examinees had to learn the new content and their access to free and low-cost preparation resources. The design committee aimed to mitigate possible unintended effects of the redesign, specifically increasing historical mean group differences in MCAT scores for examinees from lower socioeconomic status (SES) backgrounds and races/ethnicities underrepresented in medicine compared with those from higher SES backgrounds and races/ethnicities not underrepresented in medicine. In this article, the authors describe the characteristics and scores of examinees who took the new MCAT exam in 2017 and compare those trends with historical ones from 2013, presenting evidence that the diversity and performance of examinees has remained stable even with the exam’s redesign. They also describe the use of free and low-cost MCAT preparation resources and MCAT preparation courses for examinees from higher and lower SES backgrounds and who are enrolled in undergraduate institutions with more and fewer resources, showing that examinees from lower SES backgrounds and who attend institutions with fewer resources use many free and low-cost test preparation resources at lower rates than their peers. The authors conclude with a description of the next phase of this research: to gather qualitative and quantitative data about the preparation strategies, barriers, and needs of all examinees, but especially those from lower SES and underrepresented racial/ethnic backgrounds.
