A Qualitative Comparison Of General Chemistry And Advanced Placement Chemistry Students' Misconceptions Regarding Solution Chemistry, Megan J. Vandersee

Dissertations and Theses @ UNI

This study focused on identifying misconceptions which high school AP and collegiate general chemistry students hold with regards to solution chemistry topics and comparing the misconceptions held by each student group. Previous research has found that misconceptions can greatly impact students’ understanding of material and have a negative impact on student learning. However, not all solution chemistry topics had been explored in previous research. In addition, it has been suggested that collegiate students have reached a higher level of cognitive development as they are older and more advanced in their studies. If this is the case, one could assume that …

Students’ Understanding Of Finger Lakes Geology Using A Field Study, Jonathan D. Pragle

Dissertations, Master's Theses and Master's Reports

The Finger Lakes area has some of the most unique geologic features in New York State including much evidence of the impact that glaciers have had on this environment. The area is rich in Devonian and Silurian era fossils, drumlins, U-shaped valleys, and glacial erratics. With all of this evidence it is easy to imagine a class of students outside in the environment examining these structures and developing conclusions about their origin. However, students in the Finger Lakes area are generally taught about the geology of the area using traditional techniques utilizing technology and diagrams in the classroom. In this …

The Value Of Inquiry-Based Science Instruction For Elementary Students, Jessica Renae Enger

Graduate Research Papers

This review examined the academic benefits of using inquiry-based science instruction in elementary classrooms. It also examined different ways teachers integrate inquiry-based instruction. Several studies identified increases in science content knowledge, concepts, and process skills as outcomes associated with inquiry-based instruction. Other studies in this review showed mixed or negative results for academic benefits of inquiry-instruction. This review also highlights hands-on investigations, discourse, and literacy as three ways teachers integrate inquiry. Findings of this review suggest inquiry-based instruction allows students to understand difficult science concepts, justify their ideas, and can create positive attitudes toward science.

Secondary Mathematics Educators And Coaches' Role In Providing Motivation, Reggie Schulte

Honors Program Theses

The compatibility between learning goals for students and mastery-oriented athletes makes sense based on my experience in both fields. I have often heard from coaches that it is important to “embrace the process” or “trust the process.” This same idea can be applied to a mathematics secondary classroom by praising effort and embracing the struggle that comes along with having a conceptual understanding of mathematics. As a future educator and coach, it is exciting, and to be honest somewhat scary, to know that I can a great effect on what my students believe they are able to achieve. After conducting …

Increasing Student Cognitive Engagement In The Math Classroom Through Sustained Professional Development, Eva Thanheiser, Brenda Rosencrans, Kathleen Mary Melhuish, Joshua B. Fagan, Layla Guyot

Mathematics and Statistics Faculty Publications and Presentations

We share the case of one teacher engaged in professional development (PD) designed to improve collective argumentation. We present an analysis of two lessons in her classroom, one before and one after her engagement with the professional development. Findings show that the classrooms differ across both teacher support for collective argumentation (requesting ideas and elaboration vs. requesting/acts and methods), and student contributions Oustifications vs. procedures and facts) .

Connecting Teachers’ Buy-Into Professional Development With Classroom Habits And Practices, Joshua B. Fagan, Kathleen Mary Melhuish, Eva Thanheiser, Brenda Rosencrans, Layla Guyot, Jodi I. Fasteen

Mathematics and Statistics Faculty Publications and Presentations

While professional development (PD) provides an opportunity for teachers to cultivate skills that are consistent with best practices in the field, it is their buy-into the PD that ultimately determines the effectiveness of the PD. We examined how teacher buy-in affected the classroom habits and practice of four elementary teachers who took part in a district wide PD. Using baseline and first-year implementation video recordings, in conjunction with frameworks for discourse analysis, cognitive demand, and tools built specifically to measure PD implementation, we found that varying combinations of teachers' beliefs served as a mitigating factor for PD implementation.

A Multiple Case Narrative Examining The Experiences Of Alumni Of A Minority Research And Training Program, Gretchen Schneider Burton

LSU Doctoral Dissertations

The implementation of minority research and training (MRT) programs at the post secondary level has risen to close the educational achievement gap and build undergraduate pathways to generate a highly skilled and diverse STEM pool. Although the numbers of advanced science related degrees have slowly increased over the past decade, partially due to the utilization of MRT programs, this increase has not been adequate to establish an impactful representation in either academic or industry research careers. Numerous studies identify various support interventions influencing positive outcomes among MRT participants achieving graduate degrees. However, majority of the studies utilize quantitative or a …

Effectiveness Of A Corequisite Delivery Model For Developmental Mathematics, Katherine E. Fair

Online Theses and Dissertations

The purpose of this quantitative quasi-experimental study is to determine the effectiveness of a corequisite delivery model for developmental math students at a 4-year public institution. Nationally, close to fifty percent of incoming college students are placed in non-credit bearing remedial courses (Complete College America, 2012). Students must pass the remedial course before they can take the gateway college-level course. Data show that the traditional delivery of a non-credit-bearing remedial course before taking a credit-bearing course appears to help only a small percentage of students (Complete College America, 2012). The low pass rate of remedial courses supports the current trend …

Early Research: Becoming By Doing, Desmond H. Murray

Faculty Publications

"The overwhelming evidence from

different fields of study indicates that our high school students are not too young to research. One such study — “Scientific Thinking in Young Children: Theoretical Advances, Empirical Research, and Policy Implica - tions” — was reported by Science magazine in 2012 by Professor Alison Gopnik of the University of California, Berkeley. These studies all confirm the “ole folks tales” about the inquisitive, forever questioning and curious nature of young children. Indeed, about 400 years ago in 1620, the reputed father of the scientific method, Francis Bacon, wrote in Novum Organum that we “must become as …

The Bamboo Ceiling: A Study Of Barriers To Asian American Advancement, Emily Cheng

UROP Posters

The idea of cultural diversity in the workplace is a popular one, generating much discussion about the inclusion of and affirmative action toward minorities. However, these conversations rarely involve Asian Americans, who despite above-average levels of educational achievement, household income, and employment, find themselves underrepresented in and shut-out of upper-level management positions. In this project, I investigated the stereotype of East-Asian Americans as a model minority (created by non-Asians) to find out why East-Asian Americans are underrepresented in upper-level management in corporate workplaces, a phenomenon known as the “bamboo ceiling.” I explored a variety of scholarly sources that analyzed the …

Exploring The Impact Of Postgraduate Preservice Primary Science Education On Students’ Self-Efficacy, Christina Maria Norris

Theses: Doctorates and Masters

The effectiveness of science teaching in primary school is dependent upon teachers’ self-efficacy to teach science. Low self-efficacy has been linked to avoidance of teaching primary science; therefore, preservice teacher self-efficacy requires fostering to have graduates keen to teach primary science. Through an embedded mixed method intrinsic-case study, this research explored the impact of postgraduate preservice primary science education on students’ self-efficacy. This research examined the postgraduate students’ self-efficacy as the lens to determine the effectiveness of the design and pedagogical instruction of the unit and its tutors. Data sources included the use of pre/post surveys encompassing the Science Teaching …
