University Faculty And Their Knowledge & Acceptance Of Biological Evolution, Justin W. Rice, Michael P. Clough, Joane K. Olson, Dean C. Adams, James T. Colbert Dec 2015

University Faculty And Their Knowledge & Acceptance Of Biological Evolution, Justin W. Rice, Michael P. Clough, Joane K. Olson, Dean C. Adams, James T. Colbert

Ecology, Evolution and Organismal Biology Publications

Misconceptions about biological evolution specifically and the nature of science in general are pervasive in our society and culture. The view that biological evolution explains life’s origin(s) and that hypotheses become theories, which then become laws are just two examples of commonly held misconceptions. These misconceptions are reinforced in the media, in people’s personal lives, and in some unfortunate cases in the science classroom. Misconceptions regarding the nature of science (NOS) have been shown to be related to understanding and acceptance of biological evolution. Previous work has looked at several factors that are related to an individual ...


Understanding Atmospheric Carbon Budgets: Teaching Students Conservation Of Mass, Collin Peter Reichert, Cinzia Cervato, Dale Niederhauser, Michael D. Larsen Aug 2015

Understanding Atmospheric Carbon Budgets: Teaching Students Conservation Of Mass, Collin Peter Reichert, Cinzia Cervato, Dale Niederhauser, Michael D. Larsen

Geological and Atmospheric Sciences Publications

In this paper we describe student use of a series of connected online problem-solving activities to remediate atmospheric carbon budget misconceptions held by undergraduate university students. In particular, activities were designed to address a common misconception about conservation of mass when students assume a simplistic, direct relationship between atmospheric CO2 concentrations and carbon emissions. This particular misconception was challenged through an instructional intervention applying constructivist learning theory principles in an effort to prompt cognitive dissonance and induce conceptual change. This study is based on 1 y of data collected from a survey completed by introductory physical geology students (n ...


Earth Wind & Fire: A Learning Community Approach To Build Ties Between Degree Programs In A Geoscience Department, Cinzia Cervato, David Flory Feb 2015

Earth Wind & Fire: A Learning Community Approach To Build Ties Between Degree Programs In A Geoscience Department, Cinzia Cervato, David Flory

Geological and Atmospheric Sciences Publications

We describe the components of a learning community program for meteorology, geology, and Earth Science undergraduates in a geoscience department. The learning community provides the students with opportunities to interact with each other and with faculty, and it helps them in the transition from high school to a large public university. Enrollment data show that, in addition to being a successful community-building approach, the learning community has a positive impact in major retention to the programs and is well received by the students.

Preservice Teachers' Strategies To Support English Learners, Zandra De Araujo, Ji Yeong I, Erin Smith, Matthew Sakow

Education Conference Presentations, Posters and Proceedings

Although English language learners (ELLs) are one of the fastest growing groups of students in the United States, many teacher preparation programs have yet to require preservice teachers (PSTs) to receive training in effective practices for teaching ELLs. We examined a four-week field experience pairing an elementary PST with an ELL. We examined the strategies PSTs used to support ELLs as they implemented cognitively demanding mathematics tasks. Through interviews, observations, and written reflections, we found that the PSTs tried to support students, with varying degrees of success, by allowing for multiple modes of communication, including visual supports, pressing for explaining ...


Teacher Perspectives On Mathematics Education Of Language Learners: Adapting Ell Education Models, Ji Yeong I, Hyewon Chang Jan 2015

Teacher Perspectives On Mathematics Education Of Language Learners: Adapting Ell Education Models, Ji Yeong I, Hyewon Chang

Education Conference Presentations, Posters and Proceedings

Teachers in Korea have recently confronted new challenges as the population of linguistically and culturally diverse students increases. Ethnically diverse students as well as Korea-born students returning from long residences in foreign countries have great difficulties orienting themselves within Korean schools due to lack of Korean language proficiency and cultural differences. We named this student group as Korean language learners (KLLs) and investigated teacher perspectives on effective mathematics pedagogy for KLLs. Using two educational models for English language learners (ELLs)—Cummins’ Quadrant Model and the Sheltered Instruction Observation Protocol (SIOP) Model—we examined survey results of a small group of ...

Philosophical And Educational Perspectives On Engineering And Technological Literacy, Ii, Russell Korte, Mani Mina, Iraj Omidvar, Stephen T. Frezza, David A. Nordquest, Alan Cheville

Electrical and Computer Engineering Books

Unknown to each other two groups of engineers and engineering educators began to consider aspects of philosophy and engineering. One held a workshop of engineers and philosophers- “Engineering meets Philosophy” at Delft University and the other held a special session at the annual Frontiers in Education Conference on engineering education and philosophy. Since then the former has held a biannual workshop that have resulted in two impressive publications. The other continued its discussions through FIE and ASEE conferences. There are now regular sessions on philosophy and engineering education at the annual FIE conferences.

Research focused on improved understanding of six fundamental nature of science (NOS) concepts made explicit in the stories, recollection of historical examples from the stories that supported student NOS thinking; student attitudes toward historical stories in comparison to traditional textbook readings as well as student attitudes regarding scientists and the development of science ideas. Data collection included surveys over six NOS concepts, attitudes towards science and reading, and ...


Analyzing The Role Of Science Practices In General Chemistry Courses And Assessments, Jessica Jewett Reed Jan 2015

Analyzing The Role Of Science Practices In General Chemistry Courses And Assessments, Jessica Jewett Reed

Graduate Theses and Dissertations

Efforts to reform science education, such as the Next Generation Science Standards (NGSS), call for a shift away from rote learning over a breadth of content topics toward a deeper conceptual understanding of both content knowledge and skill within a discipline. Science practices are a key component of the NGSS, and combine knowledge and skill to emphasize what a student should be able to do with course content. As the NGSS are implemented on a broader scale, new methods of assessment will be needed that incorporate measures of student performance beyond content proficiency. While these reform efforts are aimed at ...

Geological and Atmospheric Sciences Publications

Lab components of undergraduate science courses typically have students complete highly directed cookbook-like laboratory activities. These experiences rarely engage students in a meaningful manner and do not accurately convey what the work of science entails. With funding from the Howard Hughes Medical Institute (HHMI), we have created more authentic science research experiences in a variety of undergraduate science courses, including introductory courses. Achieving this among the diversity of freshmen and sophomore science courses—each typically serving hundreds of students on our campus—required careful planning and adaptation. This article describes the many challenges we faced in our effort to create ...


Methods For Addressing Missing Data With Applications From Acs Exams, Alexandra Brandriet, Thomas Holme Jan 2015

Methods For Addressing Missing Data With Applications From Acs Exams, Alexandra Brandriet, Thomas Holme

Chemistry Publications

As part of the ACS Examinations Institute (ACS-EI) national norming process, student performance data sets are collected from professors at colleges and universities from around the United States. Because the data sets are collected on a volunteer basis, the ACS-EI often receives data sets with only students’ total scores and without the students’ responses to individual exam questions. Nonetheless, several national norming statistics require students’ item responses. This data return leads to missing data and potentially biased results when inferences are made based on that data set. This work uses student performance data sets from ACS-EI to consider how methods ...

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.


Development Of The Exams Data Analysis Spreadsheet As A Tool To Help Instructors Conduct Customizable Analyses Of Student Acs Exam Data, Alexandra Brandriet, Thomas Holme Jan 2015

Development Of The Exams Data Analysis Spreadsheet As A Tool To Help Instructors Conduct Customizable Analyses Of Student Acs Exam Data, Alexandra Brandriet, Thomas Holme

Chemistry Publications

The American Chemical Society Examinations Institute (ACS-EI) has recently developed the Exams Data Analysis Spread (EDAS) as a tool to help instructors conduct customizable analyses of their student data from ACS exams. The EDAS calculations allow instructors to analyze their students’ performances both at the total score and individual item levels, while also providing national normative results that can be used for comparison. Additionally, instructors can analyze results based on subsets of items of their choosing or items based on the “big ideas” from the Anchoring Concepts Content Map (ACCM). In order to evaluate the utility and usability of the ...

This study sought to identify Iowa agricultural educators’ practices, attitudes, and needs regarding agricultural safety and health (ASH). Nearly 85% of high school agricultural educators reported teaching ASH in some capacity. The most commonly taught topics included animal safety, welding safety and power tool safety. Iowa agricultural educators rated, using a Likert scale, the importance of topic within ASH education. All topics presented were believed to be important, with machinery safety, tractors safety, and ATV safety rated the most important. Personal health topics including hearing protection and thermal protection were perceived as less important. Most educators believe the ASH materials ...


Biochemistry Instructors’ Views Toward Developing And Assessing Visual Literacy In Their Courses, Kimberly J. Linenberger, Thomas Holme Jan 2015

Biochemistry Instructors’ Views Toward Developing And Assessing Visual Literacy In Their Courses, Kimberly J. Linenberger, Thomas Holme

Chemistry Publications

Biochemistry instructors are inundated with various representations from which to choose to depict biochemical phenomena. Because of the immense amount of visual know-how needed to be an expert biochemist in the 21st century, there have been calls for instructors to develop biochemistry students’ visual literacy. However, visual literacy has multiple aspects, and determining which area to develop can be quite daunting. Therefore, the goals of this study were to determine what visual literacy skills biochemistry instructors deem to be most important and how instructors develop and assess visual literacy skills in their biochemistry courses. In order to address these goals ...


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

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

Chemistry Publications

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 ...


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 ...

The emergence of students using cell phones and particularly the photographic capabilities of smartphones to cheat on exams is noted. The specific threat this form of academic misconduct poses to the ACS Examinations Institute is addressed in particular.


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 ...


A Historical Investigation Into Item Formats Of Acs Exams And Their Relationships To Science Practices, Alexandra Brandriet, Jessica J. Reed, Thomas Holme Jan 2015

A Historical Investigation Into Item Formats Of Acs Exams And Their Relationships To Science Practices, Alexandra Brandriet, Jessica J. Reed, Thomas Holme

Chemistry Publications

The release of the NRC Framework for K-12 Science Education and the Next Generation Science Standards has important implications for classroom teaching and assessment. Of particular interest is the implementation of science practices in the chemistry classroom, and the definitions established by the NRC makes these objectives much more tangible. However, this still may leave some wondering about how to begin making these changes. Mid-twentieth century chemical educators and pioneers of the first ACS exams advocated for testing science thinking and skills as early as the 1930s, and this necessitates a discussion about how early ACS exams measured these attributes ...
