The Acs Exams Institute Undergraduate Chemistry Anchoring Concepts Content Map Iv: Physical Chemistry, Thomas A. Holme, Jessica J. Reed, Jeffrey R. Raker, Kristen L. Murphy Feb 2018

The Acs Exams Institute Undergraduate Chemistry Anchoring Concepts Content Map Iv: Physical Chemistry, Thomas A. Holme, Jessica J. Reed, Jeffrey R. Raker, Kristen L. Murphy

The ACS Examinations Institute has been developing Anchoring Concepts Content Maps to provide an organizational template for the four-year undergraduate chemistry curriculum. In order to accomplish this goal, specific subdisciplinary versions of the map share the two top levels but distinguish themselves at the bottom two levels which contain finer-grained content details. This structure has been refined and vetted over a number of meetings and workshops. This paper presents the four levels of the content map for physical chemistry.

Chemistry Publications

For the past eight years, the ACS Examinations Institute has been developing Anchoring Concepts Content Maps for the different subdisciplines taught throughout the undergraduate curriculum. The structure of the map consists of two top levels that are shared throughout the entire curriculum and two subdiscipline specific levels that contain finer-grained content details. This paper presents the four levels of the content map for inorganic chemistry.


Beyond “Inert” Ideas To Teaching General Chemistry From Rich Contexts: Visualizing The Chemistry Of Climate Change (Vc3), Peter G. Mahaffy, Thomas A. Holme, Leah Martin-Visscher, Brian E. Martin, Ashley Versprille, Mary Kirchhoff, Lallie Mckenzie, Marcy Towns Aug 2017

Chemistry Publications

As one approach to moving beyond transmitting “inert” ideas to chemistry students, we use the term “teaching from rich contexts” to describe implementations of case studies or context-based learning based on systems thinking that provide deep and rich opportunities for learning crosscutting concepts through contexts. This approach nurtures the use of higher-order cognitive skills to connect concepts and apply the knowledge gained to new contexts. We describe the approach used to design a set of resources that model how rich contexts can be used to facilitate learning of general chemistry topics. The Visualizing the Chemistry of Climate Change (VC3) initiative ...


Building A Database For The Historical Analysis Of The General Chemistry Curriculum Using Acs General Chemistry Exams As Artifacts, Cynthia J. Luxford, Kimberly J. Linenberger, Jeffrey R. Raker, John Y. Baluyut, Jessica J. Reed, Chamila De Silva, Thomas Holme Jan 2015

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 ...


Updating The General Chemistry Anchoring Concepts Content Map, Thomas Holme, Cynthia Luxford, Kristen Murphy Jan 2015

Updating The General Chemistry Anchoring Concepts Content Map, Thomas Holme, Cynthia Luxford, Kristen Murphy

Chemistry Publications

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.


What Do Conceptual Holes In Assessment Say About The Topics We Teach In General Chemistry?, Cynthia J. Luxford, Thomas Holme Jan 2015

What Do Conceptual Holes In Assessment Say About The Topics We Teach In General Chemistry?, Cynthia J. Luxford, Thomas Holme

Chemistry Publications

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 ...


Defining Conceptual Understanding In General Chemistry, Thomas Holme, Cynthia J. Luxford, Alexandra Brandriet Jan 2015

Defining Conceptual Understanding In General Chemistry, Thomas Holme, Cynthia J. Luxford, Alexandra Brandriet

Chemistry Publications

Among the many possible goals that instructors have for students in general chemistry, the idea that they will better understand the conceptual underpinnings of the science is certainly important. Nonetheless, identifying with clarity what exemplifies student success at achieving this goal is hindered by the challenge of clearly articulating what conceptual understanding entails. While this may be a case of “we know it when we see it”, the design of assessments ultimately requires a specific definition of conceptual understanding. Without such a specific definition of the construct, it may be readily argued that a proposed measure does not provide evidence ...


Results Of A National Survey Of Biochemistry Instructors To Determine The Prevalence And Types Of Representations Used During Instruction And Assessment, Kimberly J. Linenberger, Thomas Holme Jan 2014

Results Of A National Survey Of Biochemistry Instructors To Determine The Prevalence And Types Of Representations Used During Instruction And Assessment, Kimberly J. Linenberger, Thomas Holme

Chemistry Publications

Chemists and chemistry educators have long sought meaningful ways to visualize fundamentally abstract components, such as atoms and molecules, of their trade. As technology has improved, computer-based visualization methods have infused both research and education in chemistry. Biochemistry, in particular, has become highly dependent on ways that large molecular systems can be represented, and how to best focus attention on the most critical aspects of the molecular system. To better understand the current state of educational efforts related to visual literacy, a needs assessment was developed and administered to a national sample of biochemistry instructors at four-year institutions (N = 536 ...

The Acs Exams Institute Undergraduate Chemistry Anchoring Concepts Content Map I: General Chemistry, Thomas Holme, Kristen L. Murphy

Chemistry Publications

To provide tools for programmatic assessment related to the use of ACS Exams in undergraduate chemistry courses, the ACS Exams Institute has built a content map that applies to the entire undergraduate curriculum. At the top two levels, the grain size of the content classification is large and spans the entire undergraduate curriculum. At the bottom two levels, the grain size of the content is more fine and tuned to specific course levels of the curriculum. This paper presents all four levels of the map as identified for first-year general chemistry.


Introducing Proper Chemical Hygiene And Safety In The General Chemistry Curriculum, Gordon J. Miller, Stephen A. Heideman, Thomas Greenbowe Jan 2000

Introducing Proper Chemical Hygiene And Safety In The General Chemistry Curriculum, Gordon J. Miller, Stephen A. Heideman, Thomas Greenbowe

Chemistry Publications

Chemical safety is an important component of science education for everyone, not just for chemistry majors. Developing a responsible and knowledgeable attitude towards chemical safety best starts at the early stages of a student's career. In many colleges and universities, safety education in undergraduate chemistry has been relegated primarily to a few regulatory documents at the beginning of a laboratory course, or an occasional warning in the description of a specific experiment in a prelaboratory lecture. Safety issues are seldom raised in general chemistry or organic chemistry lecture-based chemistry courses. At Iowa State University we have begun to implement ...
