Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas Jan 2018

Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas

Graduate Theses and Dissertations

Effective early science learning opportunities are critical for young children to build a solid foundation for subsequent development of concepts, as well as positive attitudes towards science (Eshach & Fried, 2005). However, these opportunities are often lacking in typical preschool classrooms (Connor, Morrison, & Slominski, 2006; Early et al., 2010). A multiple case study design was used to examine science learning opportunities in preschool classrooms using the Project Approach (PA; Helm & Katz, 2011). Guided by theoretical tenets from Dewey, Piaget, and Vygotsky, this study sought to explore the feasibility and efficacy of using the PA to promote high-quality science learning opportunities by examining the specific strategies teachers used to plan for authentic and meaningful experiences, structure the environment ...


Exploring The Relationship Between Beginning Science Teachers’ Practices, Institutional Constraints, And Adult Development, Jesse Wilcox Jan 2017

Exploring The Relationship Between Beginning Science Teachers’ Practices, Institutional Constraints, And Adult Development, Jesse Wilcox

Furthermore, this study sought to explore if a relationship existed between teachers’ understanding and implementation of research-based science teaching practices, the barriers to enacting these practices—known as institutional constraints, and the constructive-developmental theory which explores meaning-making systems known as orders of consciousness. As a naturalistic inquiry mixed methods study, data were collected using both qualitative (e.g., semi-structured interviews, field notes) as well as ...


Distributed Leadership For Equity And Excellence In Mathematics: An Elementary School Case Study, Comfort Enono Akwaji-Anderson Jan 2017

Distributed Leadership For Equity And Excellence In Mathematics: An Elementary School Case Study, Comfort Enono Akwaji-Anderson

Graduate Theses and Dissertations

The need for schools to develop and implement actions that will clearly improve the academic performance of all children is of great importance. Schools face pressure to improve K-12 mathematics instruction to reach all students, regardless of economic, linguistic, or cultural background (NCSM, 2008, 2016). Supporting academic excellence and equity in school mathematics requires strong leadership (Blankstein & Noguera, 2015). Recognizing that leadership in a school does not fall on the shoulders of just one person (Spillane & Healey, 2010, p. 256), the purpose of this case study was to explore the “how” of leadership, specifically the leadership practices that get us to the “why” (e.g., equity) and “what” (e.g., leadership for excellence) of mathematics education. The overarching question driving this research was: “What are the leadership practices that are intended to promote equity and excellence in mathematics education?” Using Spillane, Halverson, & Diamond’s Distributed Leadership Perspective (2004), the goal was to understand the respective distributed roles teachers and other individuals took in the process of achieving equity and excellence in mathematics at one elementary school. Formal (e.g., Head of School, Central Office Administrator) and Informal (e.g., teachers and parents) leaders were interviewed and observed. Data analysis focused on identifying the macro-functions (e.g., overall leadership practices) and micro-tasks (e.g., day-to-day, short-term tasks) that leaders engaged in to promote equity and excellence. Leadership practices were focused in three areas: Supporting the Teaching/Learning of all Students; Supporting the Teaching of Diverse Students; and Parent/Family Connection. Five primary categories of leadership practices were identified: Relationship, Instruction Support, School Climate, and Parent Involvement.

Despite the importance of family engagement, teachers faced challenges communicating to parents, getting them to help with ...

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 ...

Faculty Views Of Developmental Math Instruction At An Urban Community College: A Critical Pedagogy Analysis, Chad Everett Kee Jan 2013

Faculty Views Of Developmental Math Instruction At An Urban Community College: A Critical Pedagogy Analysis, Chad Everett Kee

Graduate Theses and Dissertations

ABSTRACT

A disproportionate number of students entering postsecondary education are considered academically unprepared and not ready for college-level work (ACT, 2011). A majority of those students are students of color, particularly those who identify as African-American or Latino and come from low-income families (Bragg, Eunyoung, & Barnett, 2006; Green, 2006; Ogbu, 1990). Due to the lack of readiness, colleges and universities, specifically community colleges, are challenged to meet the academic needs of students by offering developmental education courses such as Developmental English and/or Developmental Math. Mathematics in postsecondary education has been proven to be a gatekeeper regarding college completion due to math ...

A Comparative Study Of Pre-Service Teachers' Understandings Of The Equal Sign, Julie Ellen (Buddenhagen) Hartzler Jan 2013

A Comparative Study Of Pre-Service Teachers' Understandings Of The Equal Sign, Julie Ellen (Buddenhagen) Hartzler

Graduate Theses and Dissertations

This multipart study looked at pre-service teachers' (PSTs') understandings of the equal sign using an experimental measure, the EQ score. The data were analyzed for PSTs as a group and cross-sectionally at three key points during their elementary teacher education program. Relationships between equal sign understandings and other variables (e.g., endorsement, teaching mathematics confidence ranking, Mathematical Knowledge for Teaching (MKT) scores) were explored. Results indicate that most PSTs vary in their understanding of the equal sign with very few consistently exhibiting a fully relational view of the symbol. PSTs struggled to define the equal sign in a relational manner ...

Dissertation Abstract

Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with peers and in facilitation by the instructor. A student-centered active learning approach may be an effective way to enhance student understanding of concepts in the laboratory. The dissertation research work explores the impact of laboratory instruction and its relevance for college-level chemistry. Each chapter is different from the ...


Sustainable Soils, Sustainable Communities: Promoting The Environmental And Social Sustainability Of Human-Soil Interactions In Iowa, Eric Britt Moore Jan 2012

Sustainable Soils, Sustainable Communities: Promoting The Environmental And Social Sustainability Of Human-Soil Interactions In Iowa, Eric Britt Moore

Graduate Theses and Dissertations

Few environmental factors play as significant a role in shaping ecological and social communities as soil. Soil performs a number of functions that are critical to humanity. The incredible capacity of soil to support life does not make it immune to abuse. Although agriculture is often cited as the primary culprit, the degradation of soils is not limited to farmers. Urban populations also contribute to soil degradation through ignorance and tacit support of unsustainable soil management practices. If unsustainable soil management practices are to be stopped, then both rural and urban populations must take action to better understand and interact ...
