Teaching And Learning Algebra 1 Via An Intelligent Tutor System: Effects On Student Engagement And Achievement, Karen Kerner Lucas

Doctoral Dissertations

This study investigated the implementation and outcomes of blended learning that integrated Apangea Math, an online intelligent tutor system (ITS), with face-to-face instruction for the teaching and learning of Algebra 1. It took place in a Title I urban high school where 75 ninth grade students and their teachers enacted the blended learning program for one semester. Students from the same high school who received face-to-face instruction alone during a previous semester served as a comparison group. Flow theory was proposed as an explanation for why the ITS program was expected to increase student engagement and improve student achievement.

Teacher Perceptions Of Their Science Teaching And Student Learning For Diverse Learners, Yolanda Kirkpatrick

Doctoral Dissertations

The attention to the preparation of science education teachers is important to facilitate equitable learning opportunities and participation in science experiences (American Association for the Advancement of Science, 1990; Lee & Buxton, 2010; Sirin, 2005). Disproportionate numbers of teachers are inadequately prepared to teach diverse learners (Darling-Hammond & Bransford, 2005; Irvine, 2003; Murnane & Phillips, 1981; Oakes, 1990; Zeichner, 1992). Wise (2001) describes teacher preparation in this country as the dirty little secret in education. By this, Wise was referring to the inadequate education and training of teachers that remained a silent part of the discourse on teacher preparation.

Sketchmate: A Computer-Aided Sketching And Simulation Tool For Teaching Graph Algorithms, Kristy Sue Van Hornweder

Doctoral Dissertations

In this dissertation, we developed and tested a sketching, visualization, and simulation tool called Sketchmate for demonstrating graph algorithms commonly taught in undergraduate computer science courses. For this research, we chose to focus on shortest path and network flow algorithms. Two versions of this tool have been implemented: 1) an instructor tool that supports computer-aided manual simulations of algorithms that augment traditional whiteboard presentations, allowing lectures to be more dynamic and interactive, and 2) a student tool that supports computer-aided manual practice of algorithms that enables students to work through homework problems more quickly while providing detailed incremental feedback about …

Deaf Education Preservice Teachers’ Perceptions Of Scientific Inquiry And Teaching Science To Deaf And Hard Of Hearing Students, Shannon Carol Graham

Doctoral Dissertations

The purpose of this dissertation was to describe preservice teachers’ perceptions of scientific inquiry and science teaching to deaf and hard of hearing students. Participants were four deaf education preservice teachers enrolled in a graduate level course on content area methods during their professional internship year. The instructor employed implicit and explicit reflective pedagogy for the science methods section and focused on scientific practices. Research questions guiding this study are as follows: 1) What are deaf education preservice teachers’ perceptions of scientific inquiry? and 2) What are deaf education preservice teachers’ perceptions of science teaching and learning among deaf and …

The Engineering Design Process As A Model For Stem Curriculum Design, Krystal Sno Corbett

Doctoral Dissertations

Engaging pedagogics have been proven to be effective in the promotion of deep learning for science, technology, engineering, and mathematics (STEM) students. In many cases, academic institutions have shown a desire to improve education by implementing more engaging techniques in the classroom. The research framework established in this dissertation has been governed by the axiom that students should obtain a deep understanding of fundamental topics while being motivated to learn through engaging techniques. This research lays a foundation for future analysis and modeling of the curriculum design process where specific educational research questions can be considered using standard techniques. Further, …

The Relationship Between Teacher Absenteeism And Fourth-Grade Student Mathematical Achievement, Charles Michael Brouillette

Doctoral Dissertations

Within public schools throughout the United States, an emphasis has been placed on improving education for all students. In turn, this has resulted in legislators and policymakers placing an emphasis on assessing student learning and holding the education community accountable. In this study, the researcher examined one variable in the accountability effort: teacher absenteeism. The major purpose of this study was to examine the relationship between teacher absenteeism and fourth-grade student mathematical achievement.

Data for this study were generated from nine school districts located in northern Louisiana. Data consisted of attendance records of fourth-grade teachers and student performance on the …

The Separate And Collective Effects Of Personalization, Personification, And Gender On Learning With Multimedia Chemistry Instructional Materials, Shannon James Halkyard

Doctoral Dissertations

Chemistry is a difficult subject to learn and teach for students in general. Additionally, female students are under-represented in chemistry and the physical sciences. Within chemistry, atomic and electronic structure is a key concept and several recommendations in the literature describe how this topic can be taught better.

These recommendations can be employed in multimedia instructional materials designed following principles understood through the Cognitive Theory of Multimedia Learning. Additionally, these materials can expand the known use of principles like personalization (addressing the learner as "you") and test prospective design principles like personification (referring to abstract objects like atoms as "she" …

Investigation Of The Misconceptions Related To The Concepts Of Equivalence And Literal Symbols Held By Underprepared Community College Students, Terrence Joseph Maguire

Doctoral Dissertations

Many students struggle to learn mathematics in K-8 grades. Research has shown that lower grade students often misconceive equivalence as an operation rather than a relation, and that students also form various misconceptions of literal symbols. Many students arrive at college seriously underprepared in mathematics, but there is scant research on the difficulties and misconceptions of these college students. The purpose of this research was to learn if underprepared community college students harbor misconceptions of equivalence and of literal symbols similar to K-8 students.

For this study, 191 underprepared college students were surveyed for misconceptions by a questionnaire of 43 …
