The previously published Anchoring Concepts Content Map (ACCM) from the ACS Examinations Institute is updated. Through the development process of the ACCM for other subdisciplines, changes have been made at the top two levels, and these changes need to be reflected in the previously published maps. In addition, a large-scale project to align test items from ACS Exams over the past 20 years revealed specific omissions in the initially published General Chemistry ACCM.

As a discipline, chemistry enjoys a unique position. While many academic areas prepared “cooperative examinations” in the 1930s, only chemistry maintained the activity within what has become the ACS Examinations Institute. As a result, the long-term existence of community-built, norm-referenced, standardized exams provides a historical artifact about the nature of content coverage in courses that stretches over decades. This work reports efforts to capture information and formulate it into a database about general chemistry content coverage over the past 20 years. Roughly 2000 items have been characterized in several ways, including (i) content, using an Anchoring Concepts Content Map; (ii ...

Introductory chemistry has long been considered a service course by various departments that entrust chemistry departments with teaching their students. As a result, most introductory courses include a majority of students who are not chemistry majors, and many are health and science related majors who are required to take chemistry. To identify content areas that are either well covered or sparsely covered, approximately 2000 exam items from four types of General Chemistry ACS exams (Full Year General Chemistry, General Chemistry Conceptual, First Term General Chemistry, and Second Term General Chemistry) spanning two decades were aligned to the Anchoring Concepts Content ...
