Misconceptions On Part-Part-Whole Proportional Relationships Using Proportional Division Problems, Ji-Yeong I, Ricardo Martinez, Barbara Dougherty Nov 2018

Misconceptions On Part-Part-Whole Proportional Relationships Using Proportional Division Problems, Ji-Yeong I, Ricardo Martinez, Barbara Dougherty

Education Publications

This study focuses on proportional division, a specific problem type of proportions and proportional relationships, which embeds a part-part-whole relationship. We investigated how students in grades 6 to 9 solved and perceived three proportional division problems. Analysis of the students’ performance on the tasks revealed three types of misconceptions emerged in solving proportional division problems: regarding a ratio as a number, additive reasoning, and confusion about the whole. Confusion about the whole was the misconception that appeared most frequently across all grades. This finding suggests teachers should provide various types of proportional problems, especially with part-part-whole ratios. Proportional division is ...


Implementing Mathematical Modeling For Emergent Bilinguals, Ji Yeong I, Ricardo Martinez, Betsy A. Araujo-Grando Nov 2018

Implementing Mathematical Modeling For Emergent Bilinguals, Ji Yeong I, Ricardo Martinez, Betsy A. Araujo-Grando

Education Conference Presentations, Posters and Proceedings

In this study, a researcher collaborated with a middle school mathematics teacher through co-planning, teaching and reflecting upon mathematical modeling lessons to support emergent bilinguals to make sense of mathematics. We investigate how this collaboration impacts the process of co-teaching and co-planning in terms of the interactions between the researcher and the teacher. Our analysis reveals how each role changed and maintained during the collaboration and what factors were discussed to develop and implement modeling-based lessons for emergent bilinguals.


Origins Of Early Stem Interest For Black Male Graduate Students In Engineering: A Community Cultural Wealth Perspective, Brian A. Burt, Jarrel T. Johnson Sep 2018

Origins Of Early Stem Interest For Black Male Graduate Students In Engineering: A Community Cultural Wealth Perspective, Brian A. Burt, Jarrel T. Johnson

Education Publications

The development of talent in science, technology, engineering, and mathematics (STEM) fields remains a national priority, one for which increasing the number of STEM participants from historically underrepresented populations is germane. Increasing the number of historically underrepresented students who complete advanced degrees in STEM will not only aid in solving national problems such as building infrastructure and strengthening national security, but also provide more models of success for future generations. Addressing this priority requires developing a better understanding of what leads students into and through STEM pathways, and finding ways to eliminate systemic barriers to their participation in STEM. This ...

Data Parties I Have Known: Lessons Learned And Best Practices For Success, Nancy K. Franz

Education Publications

Increased focus on data-driven decision making requires Extension professionals to excel at data analysis and interpretation. Data parties have become increasingly popular for involving stakeholders in making sense of data. As these parties become more frequently used by Extension professionals, best practices are emerging from lessons learned to improve the process and enhance the outcomes. These practices include designing discussion questions to fit the specific goals of the process, engaging a team of key partners, setting a theme and party environment that appeals to the participants and fits the context, providing appropriate data visualization tools, and using strong facilitation practices.

Combining Academics And Social Engagement: A Major-Specific Early Alert Method To Counter Student Attrition In Science, Technology, Engineering, And Mathematics, Andrew J. Sage, Cinzia Cervato, Ulrike Genschel, Craig Ogilvie

Geological and Atmospheric Sciences Publications

Students are most likely to leave science, technology, engineering, and mathematics (STEM) majors during their first year of college. We developed an analytic approach using random forests to identify at-risk students. This method is deployable midway through the first semester and accounts for academic preparation, early engagement in university life, and performance on midterm exams. By accounting for cognitive and noncognitive factors, our method achieves stronger predictive performance than would be possible using cognitive or noncognitive factors alone. We show that it is more difficult to predict whether students will leave STEM than whether they will leave the institution. More ...


Developing The Next Generation Of Diverse Computer Scientists: The Need For Enhanced, Intersectional Computing Identity Theory, Sarah L. Rodriguez, Kathleen Lehman Apr 2018

Developing The Next Generation Of Diverse Computer Scientists: The Need For Enhanced, Intersectional Computing Identity Theory, Sarah L. Rodriguez, Kathleen Lehman

Education Publications

This theoretical paper explores the need for enhanced, intersectional computing identity theory for the purpose of developing a diverse group of computer scientists for the future. Greater theoretical understanding of the identity formation process specifically for computing is needed in order to understand how students come to understand themselves as computer scientists. To ensure that the next generation of computer scientists is diverse, this paper presents a case for examining identity development intersectionally, understanding the ways in which women and underrepresented students may have difficulty identifying as computer scientists and be systematically oppressed in their pursuit of computer science careers ...


The Personal Is Archival: Researching And Teaching With Stories Of Women Engineers, Scientists, And Doctors, Amy Bix Apr 2018

The Personal Is Archival: Researching And Teaching With Stories Of Women Engineers, Scientists, And Doctors, Amy Bix

History Conference Papers, Presentations and Posters

Personal stories from archives are essential to understand the historical gendering of American science, medicine, technology, and innovation. Advocates promoted science, medicine, and engineering to young men, yet the twentieth-century brought increasing numbers of women into STEM education and employment. This paper illustrates the above by offering guidance to key archival and digital collections that show how women (individually and as groups) made places for themselves in modern science, technology, and medicine. Sources illustrate complex intersections for women simultaneously shaping professional and personal identities. This paper suggests how historians can reach beyond individual biographies to build broader analyses that deploy ...


Using Nonfiction Narratives In An English Course To Teach The Nature Of Science And Its Importance To Communicating About Science, Jeanine Elise Aune, Lynn Lundy Evans, Nancy Boury Mar 2018

Using Nonfiction Narratives In An English Course To Teach The Nature Of Science And Its Importance To Communicating About Science, Jeanine Elise Aune, Lynn Lundy Evans, Nancy Boury

Plant Pathology and Microbiology Publications

The nature of science (NOS) is a foundational framework for understanding scientific ideas and concepts. This framework includes scientific methodology, the process of revising and interpreting data, and the ways in which science is a social endeavor. Nature of science literature treats science as a way of knowing that is based on observable phenomenon. While discipline-specific coursework teaches the factual information of science, it may fall short on teaching scientific literacy, a key component of which is understanding NOS. We have designed an English course that features nonfiction narratives describing the early days of epidemiology, hygiene awareness, and the current ...

Geological and Atmospheric Sciences Publications

This study examines the effects of an extended authentic research experience on students’ understanding of the nature of science (NOS) and self-efficacy toward science. The curriculum of an introductory physical geology lab was transformed to include a six-week, student-driven research project focused on local groundwater and surface water issues. Students’ NOS understanding was measured by using a modified version of the Student Understanding of Science and Scientific Inquiry questionnaire (n = 181) and their science self-efficacy using a modified vocational self-efficacy survey (n = 179). Data were collected on students during four semesters. We found that the combination of having students explicitly ...

Chemistry Publications

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.

Student And Faculty Views On Process Of Science Skills At A Large, Research-Intensive University, Elizabeth A. Addis, Jo Anne Powell-Coffman

Genetics, Development and Cell Biology Publications

The Association of American Colleges and Universities ranks multiple process of science (POS) skills among the top-10 skills employers seek in college graduates. As part of an effort to explore and align the emphasis on POS skills in our science departments, we sought three things: (a) to determine if faculty and students felt enough time was devoted to POS skills, (b) to identify the skills that science students and faculty felt were important to acquire from an undergraduate education, and (c) to evaluate whether there were differences in these views among disciplines. We found that faculty and students agreed on ...


Do Social Justice Contexts Matter In Mathematical Modeling?: Modeling Problem Analysis, Ji Yeong I, Ji-Won Son, Hyunyi Jung Jan 2018

Do Social Justice Contexts Matter In Mathematical Modeling?: Modeling Problem Analysis, Ji Yeong I, Ji-Won Son, Hyunyi Jung

Education Publications

Since the Common Core State Standards for Mathematics (CCSSM; NGA Center for Best Practices & CCSSO, 2010) include modeling as one of the eight Standards for Mathematical Practices for all grades but also as important conceptual category in high school mathematics, there have been a spotlight on mathematical modeling and demand for teachers to deliberately integrate modeling tasks in mathematics classrooms. One of the efforts to integrate modeling in mathematical curricula is including modeling problems in textbooks. It is necessary to examine if these attempts are adequately made in mathematical curricula (Meyer, 2015).

Integrating Online Instruction And Hands-On Laboratory Activities For Summer Learning For Students Of Color: A Design Case In Forensic Science, Douglas Elrick, Jiaqi Yu, Connie Hargrave

Education Publications

The popularity of TV shows such as Crime Scene Investigation (CSI) has generated high school students’ interest in forensics. Yet, forensic science is not commonly accessible to students, and especially students of color who often attend under-resourced high schools. This article presents the design, development, and evaluation of an online forensics course created for high school students of color who were a part of an informal science, technology, engineering, and mathematics (STEM) educational development program. Two essential elements guided the course design: the target learners (high school students of color) and integrating online instruction and hands-on laboratory activities involving real-world ...
