Relative Impacts Of Different Grade Scales On Student Success In Introductory Physics, David J. Webb, Cassandra A. Paul, Mary A. Chessey

Faculty Publications

In deciding on a student’s grade in a class, an instructor generally needs to combine many individual grading judgments into one overall judgment. Two relatively common numerical scales used to specify individual grades are the 4-point scale (where each whole number 0–4 corresponds to a letter grade) and the percent scale (where letter grades A through D are uniformly distributed in the top 40% of the scale). This paper uses grading data from a single series of courses offered over a period of 10 years to show that the grade distributions emerging from these two grade scales differed in many …

Exploring Career Change Transitions Through A Dialogic Conceptualization Of Science Teacher Identity, Lara Smetana, Ali Kushki

Education: School of Education Faculty Publications and Other Works

Research into the construct of science teacher identity has gained momentum over the past decade in an effort to achieve a more comprehensive, holistic understanding of teacher learning and development. As yet few studies have examined the unique identity challenges of science teacher career changers. Akkerman and Meijer’s (2011) dialogical approach to the conceptualization of teacher identity informed this longitudinal, qualitative study exploring the different identity aspects, or I-positions, of two individuals who had changed careers to teach high-school biology. The study identified moments of disequilibrium experienced by the participants and explored how they each eventually restored equilibrium. Analysis included …

Exploring The Form And The Function: A Review Of Science Discourse Frameworks In The Service Of Research And Practice, Brett A. Criswell, Gregory T. Rushton, Lisa Shah

Secondary Education Faculty Publications

The importance of how classroom discourse can be used to support science learning has gained national attention with respect to both science teaching and research across K12 and higher education. In this review article, we examine a commonly referenced set of nine frameworks for use inscienceclassrooms. Specifically, we examine the ways in which various frameworks emphasize the structure (i.e.,form) or practical use (i.e.,function) of language across classroom settings, and the impact of such an emphasis on the facilitation and analysis of science classroom discourse. The findings from this review should help researchers investigate and educators facilitate classroom discourse in ways …

Relativity Lite: A Pictorial Translation Of Einstein’S Theories Of Motion And Gravity, Jack C. Straton

PDXOpen: Open Educational Resources

Relativity Lite is designed for the General Astronomy sequence (PH 361-2U, SCI 315-6U) whose primary book glosses over Special Relativity and General Relativity while trying to explain the Cosmology that is based on those subjects. Relativity Lite translates the mathematical equations conventional relativity texts rely upon into pictures that are readily understood and contain within them the mathematical essentials. This book provides the comprehensive coverage needed to understand, in sufficient depth, these three linked areas of our reality.

Readers seeking this knowledge on their own, and those in other courses for nonscientists, may also find it helpful.

Supporting Science Learning For English Language Learners, Judith Morrison, Yuliya Ardasheva, Sarah Newcomer, Lindsay Lightner, Gisela Ernst-Slavit, Kira Carbonneau

Journal of Educational Research and Practice

This study focused on two fourth-grade science classrooms with English learners (ELs), exploring how teachers supported students’ science and language/literacy learning in different language contexts. Three a priori research-based practices recommended for supporting science learning framed our exploration: (a) negotiation, opportunities for individual and social construction and critique of knowledge; (b) embedded language, opportunities for language and literacy learning as a natural aspect of science; and (c) non-threatening learning environments, opportunities for social apprenticeship and interaction. We provide insights into how science instructional practices supported ELs’ science and language learning. One key implication is that enacting these three principles of …

Multicourse Comparative Study Of The Core Aspects For Flipped Learning: Investigating In-Class Structure And Student Use Of Video Resources, Nicole Naibert, Emryse Geye, Michael M. Phillips, Jack Barbera

Chemistry Faculty Publications and Presentations

Since 2013, the number of publications on flipped learning within chemistry have steadily increased. However, most of these studies focus on flipped course reforms within individual institutions, while the outcomes of any learning environment are dependent on how the environment is structured and the degree to which students interact with its elements. In this study, we apply a coordinated set of assessment practices to investigate similarities among flipped chemistry courses at five institutions in the United States. All courses in the study followed the two basic tenets of flipped learning: (1) foundational information was delivered through preclass materials (PCMs), and …

Star Stuff: Romantic Understanding Of Elementary Science And Mathematics Through Imaginative Steam Learning, Richard Cox

Graduate Theses, Dissertations, and Capstones

Mathematics Corequisite Remediation And Direct Enrollment: Addressing Misconceptions And Concerns, Zachary Beamer

Inquiry: The Journal of the Virginia Community Colleges

In Fall 2020 the VCCS will begin implementing the Direct Enrollment Pilot, building upon lessons learned in prior reforms and successes of reforms in other states. In the new corequisite model of developmental education, students at the margins of college preparation are placed directly into college coursework with a supplemental support class. This Notes in Brief article summarizes some of the research behind the transition towards this model and the implications of this scholarship on current reform efforts. It directly addresses concerns regarding the move towards corequisite instruction and provides recommendations for how to implement reforms.

Student Perceptions Of Their Undergraduate Science Laboratories, Eva N. Nyutu

Dissertations

The science laboratory learning environment has been a distinctive area in science education since the 19th century. The science laboratory environment has been examined extensively at the high school level using the Science Laboratory Environment Inventory (SLEI). There are, however, very few studies about the science laboratory environment done at the college level. An instrument that may be helpful for college instructors is one that assesses the degree to which students perceive the laboratory as intended by their science instructors. An examination of the literature indicated that there are no validated and reliable instruments for measuring student perceptions of what …

Exploring 3-5 Grade Teachers' Self-Efficacy With Inquiry-Based Science Instruction, Sarah Laden

Undergraduate Research Journal

From an early age, teachers should expose students to high-quality STEM education to allow them to explore and discover phenomena. In order to prepare students, teachers must be able to assist students and facilitate the inquiry process. Unfortunately, elementary teachers often have low self-efficacy regarding inquiry-based science and resort to instruction that is not supported by research. A survey was given to third through fifth grade teachers at a small, suburban, mid-western school district to measure their self-efficacy regarding inquiry-based science. The teachers responded to questions that asked them to rank themselves on several skills that are required to teach …

Piaac Numeracy Task Complexity Schema: Factors That Impact On Item Difficulty, Dave Tout, Iddo Gal, Mieke Van Groenestijn, Myrna Manly, Mary Jane Schmitt

Vocational, adult and professional education research

This paper describes some lessons learned from international adult numeracy assessments that can help in understanding the challenges that people, including both adults and school students, have when solving numeracy tasks and their levels of performance on functional mathematical problems. The paper presents a theoretical schema of five factors that predict, separately and in interaction, the complexity or level of difficulty of mathematically-related assessment tasks, including tasks that incorporate texts and require literacy or reading skills, which are very common in adults' lives. The model was originally developed as part of the development of the Adult Literacy and LifeSkills survey …

Toward Developing A Valid And Reliable Assessment Of Learners’ Nature Of Engineering Views, Erdogan Kaya

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nature of Engineering (NOE) refers to the epistemological beliefs pertaining to engineering (Antink-Meyer & Brown, 2019; Deniz et al., 2019; Hartman & Bell, 2018; Kaya et al., 2017; Pleasants & Olson, 2019). Given that a person’s engineering values and beliefs can affect how that individual perceives not only certain tasks, but also his/her ability to accomplish them, it is important to support pre-college teachers and students in improving their NOE understanding. This continues to be one of the main goals of pre-college Science, Technology, Engineering, and Math (STEM) education, and has become particularly relevant since the release of the Next …
