The Revised MCAT MR5 (2010-2013) – 5th MCAT Review, 5th review since 1928 Current exam was launched in 1991 Gathered input at 90 outreach events Collected survey data from 2700 medical school and baccalaureate faculty, medical students, and residents Solicited input from blue-ribbon panels and advisory committees Revised MCAT launches on April 17, 2015. 22 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

MCAT2015 will test competencies in four areas 23 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Conceptual framework for MCAT2015 Matches medical schools’ shift to competencybased curricula Increases emphasis on scientific and critical reasoning skills Asks examinees to think like scientists by bringing together concepts in the natural and social sciences And by reasoning about research designs and results and interpreting data and drawing conclusions 24 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Chemical & Physical Foundations of Biological Systems Foundational Concept 4 Content Categories 4A: 4B: 4C: 4D: 4E: Translational motion, forces, work, energy, and equilibrium in living systems Importance of fluids for the circulation of blood, gas movement, and gas exchange Electrochemistry and electrical circuits and their elements How light and sound interact with matter Atoms, nuclear decay, electronic structure, and atomic chemical behavior 25 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

How are MCAT topics chosen? Two Surveys: 1. Importance survey – medical school faculty, medical students, residents 2. What is taught survey – undergraduate natural science and social science faculty 26 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Medical school faculty and students and undergraduate faculty survey data Content topics with high importance ratings that are widely taught will be tested on the future exam. Focus will be on using that content knowledge to reason about applications to living systems Some “straight content knowledge” questions will continue to appear on the MCAT MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Mathematics and the Revised MCAT No questions involving calculus. Only a few medical schools require students to have taken calculus. Revised MCAT emphasizes (simple) statistical reasoning, modeling, analysis of data, . 34 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

How will the revised MCAT affect undergraduate curricula? 35 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Challenges for Undergraduate Faculty Devise a courses that help students meet the SFFP and other competencies Sharpen the focus of undergraduate STEM courses for life science students: not everything in the standard STEM courses is relevant to life science students Work with other STEM colleagues to streamline and focus the pre-health curriculum – investigate multidisciplinary courses MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015

Implications for STEM Courses 0th Approximation – make no changes A Bit Better – physics and chemistry should include examples from life sciences and medicine – help students with transfer of knowledge (Ross’s talk) MCAT Guide: “Focus will be on using that content knowledge to reason about applications to living systems” More biochemistry (ACS foundational level) Use SFFP Competencies and Learning Objectives as a starting point for course design. 37 MCAT is a program of the Association of American Medical Colleges and related trademarks owned by the Association includes Medical College Admissions Test, MCAT and MCAT 2015
