Argumentation In Science Class: Its Planning, Practice, And Effect On Student Motivation, Anju Taneja

Walden Dissertations and Doctoral Studies

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of argumentation and formative feedback to understand how teachers orchestrate argumentation in science class and how it affects motivation. Qualitative data was collected through interviews of 4 grade-9 science teachers and through observing teacher-directed classroom discourse. Classroom observations allowed the researcher to record the rhythm of discourse by characterizing teacher and student speech as …

Predicting Mathematics Teachers' Acceptance Of Reflective Blogging To Improve Instruction, Diana Sue Fesmire

Walden Dissertations and Doctoral Studies

An internal district audit identified that a rural, socioeconomically disadvantaged Southwestern school district has a lack of congruent and consistent implementation of the Common Core State Standards in mathematics. Innovative and cost-saving avenues for professional development (PD), such as reflective blogging, foster teacher learning to reconcile the enacted curriculum with the intended curriculum. This correlational study investigated the predictive power of technology acceptance and motivation constructs on reflective mathematics teachers' social media use intention and participation in informal, virtual Communities of Practice (vCoP). The framework that guided this study is the unified acceptance and use of technology and self-determination theory. …

Aspects Of Science Engagement, Student Background, And School Characteristics: Impact On Science Achievement Of U.S. Students, Larry J. Grabau

Theses and Dissertations--Educational, School, and Counseling Psychology

Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities.

I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. …

Practicing Positive Coping Strategies For Managing Math Anxiety In A Secondary Mathematics Classroom, Courtney Kathleen Smith-Nelson

Graduate Theses/Dissertations

The purpose of this action research study was to explore student and teacher perceptions on the usefulness of teaching students to practice positive coping strategies for managing math anxiety in a high school International Baccalaureate mathematics classroom. This study used a reflective action research methodology in which students' math anxiety levels were assessed using Alexander and Martray's Abbreviated Mathematics Anxiety Rating Scale (1989). Students were then surveyed on their use of coping strategies for managing math anxiety, presented with a variety of positive coping strategies, and asked to rate each strategy on its perceived worth and the likelihood that they …

Science Teachers’ Professional Growth And The Communication In Science Inquiry Project, Elizabeth Lewis, Dale Baker, Nievita Bueno Watts, Katrien Van Der Hoeven Kraft

Department of Teaching, Learning, and Teacher Education: Faculty Publications

The Communication in Science Inquiry Project (CISIP) a National Science Foundation-funded, standards-based model of a scientific classroom discourse community (SCDC) was designed to meet the need for highly-qualified teachers and science education reform. The model included: (a) inquiry; (b) oral discourse; (c) written discourse; (d) academic language development, and (e) learning principles. Research and evaluation feedback were mechanisms by which CISIP become self-regulating, promoting instructional change and incorporating more aspects of inquiry-based learning with academic language development strategies. The program underwent a philosophical shift from teachers-as-consumers to teachers-as-producers based on classroom observations using a professional development-aligned classroom observation instrument that …

The Road To Reform: A Grounded Theory Study Of Parents’ And Teachers’ Influence On Elementary School Science And Mathematics, Julie Thomas, Sandi Cooper

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Though elementary teacher educators introduce new, reform-based strategies in science and mathematics methods courses, researchers wondered how novices negotiate reform strategies once they enter the elementary school culture. Given that the extent of parents’ and veteran teachers’ influence on novice teachers is largely unknown, this grounded theory study explored parents’ and teachers’ expectations of children’s optimal science and mathematics learning in the current era of reform. Data consisted of semistructured, open-ended interviews with novice teachers (n = 20), veteran teachers (n = 9), and parents (n = 28). Researchers followed three stages of coding procedures to develop …

Preservice Elementary Teachers’ Science Self-Efficacy Beliefs And Science Content Knowledge, Deepika Menon, Troy D. Sadler

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Self-efficacy beliefs that relate to teachers’ motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers’ science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers’ science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief …

Zur Erinnerung An Den Mongolischen Säugetierforscher Namshil Chotolchuu (1935-1990) – Im Gedenken An Die Wiederkehr Seines 80. Geburtstages 2015, Michael Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Namshil Chotolchuu wurde am 20.01.1935 in Ulaanbaatar geboren. Sein Vater war in den 60er und 70er Jahren ein bekannter Schachmeister der Mongolei. Mit Chotolchuu verbinden uns sehr erfolgreiche und prägende gemeinsame Mongolisch-Deutsche Biologische Expeditionen und daraus resultierende Publikationen sowie eine lange Freundschaft.

Mit diesem Nachruf wollen wir an ein langes Kapitel der deutsch-mongolischen Zusammenarbeit mit Kollegen der Mongolischen Akademie der Wissenschaften und an einen Pionier der eigenständigen mongolischen Säugetierforschung erinnern, der in der internationalen Kooperation, im Team der Mongolisch-Deutschen Biologischen Expeditionen und im Schrifttum sowie ganz persönlich unvergessen bleibt.

A Mixed Methods Approach To Investigating Cognitive Load And Cognitive Presence In An Online And Face-To-Face College Algebra Course, Jodi J. Mills

Theses and Dissertations--Education Sciences

Most research on Cognitive Load Theory (Sweller, 1988) has uncovered many instructional design considerations for learning complex tasks. Additionally, the Community of Inquiry (Garrison, Anderson, & Archer, 2000) framework describes many of the learning experiences in online education. A gap existed in the literature for investigating cognitive load over the duration of a college algebra course and for investigating the relationship between cognitive load and cognitive presence. This research study has addressed this gap by investigating cognitive load and cognitive presence in an online and face-to-face college algebra course.

The results of this study revealed that face-to-face students earned statistically …

A Guided Inquiry-Based Laboratory Experiment: Synthesis And Characterization Of Various Phthiocol Complexes, Turina Jangula

The Journal of Undergraduate Research

Despite proven effectiveness of constructivist guided-inquiry based instruction for college chemistry courses, teaching in advanced chemistry courses such as inorganic chemistry remains very much traditional. This persistence of traditional instructional approaches could be attributed to the lack of inquiry-based curriculum materials for these courses. In this paper a guided-inquiry based inorganic laboratory experiment on the synthesis and characterization of phthiocol complexes with four different metals is presented along with suggestions for implementation as a laboratory activity. The experiment is unique in terms of its development based on a social constructivist framework and has student discussion and conceptual understanding of inorganic …

Variables That Impact The Implementation Of Project-Based Learning In High School Science, Kellie Renee Cunningham

Wayne State University Dissertations

Wagner and colleagues (2006) state the mediocrity of teaching and instructional leadership is the central problem that must be addressed if we are to improve student achievement. Educational reform efforts have been initiated to improve student performance and to hold teachers and school leaders accountable for student achievement (Wagner et al., 2006). Specifically, in the area of science, goals for improving student learning have led reformers to establish standards for what students should know and be able to do, as well as what instructional methods should be used. Key concepts and principles have been identified for student learning. Additionally, reformers …

Building Support For Faculty Women Of Color In Stem, Loretta A. Moore, Deidre L. Wheaton, Evelyn J. Leggette, Angela Mae Kupenda

Journal Articles

Given the national climate, higher education must continue to serve a vital role for our future, just as it has in our past. For historically Black colleges and universities (HBCUs) and other minority-serving institutions, their mission-driven role is even more urgent. Communities of color depend on these institutions to be gateways for access to jobs with higher incomes for graduates in growing fields such as science, technology, engineering, and mathematics (STEM). Hence, it is critical for these faculty women of color in STEM to have environments and networks that will help them to succeed.

Analysis Of English Language Learner Student Reasoning About Measures Of Center And Variation: A Triangulation Of Quantitative And Qualitative Data, Lorena Galvan

Open Access Theses & Dissertations

The population of Spanish-speaking English Language Learner (ELL) students has been growing rapidly in the past 20 years. It has been estimated that by the year 2018, 1 out of 4 students in grades K-12 will be an ELL. There is a large body of research about assessment of Spanish-speaking ELL students in mathematics; however, there is little that focuses on statistics only. Statistics courses are frequently confused and/or classified under mathematics courses. However, students taking an introductory statistic course are required to know a new set of concepts, words and vocabulary that are not always used in mathematics courses. …

Finding Relevance, Competence, And Enjoyment: The Development Of Domain Identification And Interest In First-Year Science Majors, Chloe Ruff

Education Faculty Publications

The purpose of this qualitative study was to examine how first-year college students perceive their development of domain identification with, and interest in, their prospective science major during their initial year of college. Four themes emerged from the coding and analysis of interviews with eight first-year science students: Self-Definition in Flux, Feeling Competent, Expressing Interest through Enjoyment, and Relevant to Me. These themes were mainly consistent with the current model of domain identification (Osborne & Jones, 2011) but differ from the current model of interest development (Hidi & Renninger, 2006). Theoretical and practical implications are included for faculty and advisors …
