Investigating The Impact Of Visuohaptic Simulations For Conceptual Understanding In Electricity And Magnetism, Karla Lizeth Sanchez Martinez

Open Access Theses

The present study examined the efficacy of a haptic simulation used as a pedagogical tool to teach freshmen engineering students about electromagnetism. A quasi-experimental design-based research was executed in two iterations to compare the possible benefits the haptic device provided to the cognitive learning of students. In the first iteration of the experiment performance of learners who used visual-only simulations was compared to the performance of those who used visuohaptic. In the second iteration of the experiment modifications were made to learning materials and experiment procedures to enhance research design. Research hypothesis states that multimodal presentation of information may lead …

Inquiry Teaching: It Is Easier Than You Think!, S. Key, D. Owens

Journal of Mathematics and Science: Collaborative Explorations

This article is a survey of the literature on inquiry teaching. Many teachers do not participate in inquiry teaching for various reasons. The following are the main reasons: it takes too much time; students do not learn what they need for the state test; and, the teachers do not know how to grade projects and presentations. These reasons sound like rhetoric from long ago, but it is very current. In this article, research is used to show that students who participate in inquiry learning or any type of problem-based education do much better than students who do not have that …

Dismantling The Birdcage : Adolescent Girls' Attitudes Towards Learning Mathematics With A Relational Pedagogy In A Problem-Based Environment, Carmel Schettino

Legacy Theses & Dissertations (2009 - 2024)

Although the Gender Achievement Gap is closing in mathematics, the "interest gap" in pursuing STEM fields is not. Mathematics education research has discussed constructivist, student-centered and inclusive methods of teaching that have been found to encourage students that have underachieved and been underrepresented in STEM fields. One recommendation for encouraging young women to continue in their mathematical studies is to find instructional methods that allow them to feel included in the learning process and "unfix" the dichotomous, gendered socio-cultural view of mathematics and the mathematics classroom fostering positive attitudes such as self-confidence, empowerment and agency.

The Impact Of Teachers' Characteristics And Self-Reported Practices On Students' Algebra Achievement, Liza Cope

Legacy Theses & Dissertations (2009 - 2024)

This study examined the impact of teachers' characteristics and self-reported practices on students' Algebra achievement while controlling for students' characteristics. This study is based on the secondary analysis of data collected from a nationally representative sample of 9th grade students and their mathematics teachers during the base year of the High School Longitudinal Study of 2009 (HSLS).

Inquiry, Efficacy, And Science Education, Heather Christa Scott

College of Graduate Studies: Theses & Dissertations

Developing learners who are equipped to think critically about the vast information circulating around them is essential in their preparation for a role in society today. The use of effective inquiry-based instruction is not a widespread practice among K-12 classrooms. Many secondary and post-secondary science instructors see the valuable link between students asking questions and the development of critical thinking. Inquiry-based instruction provides student opportunities to ask questions, design methods of investigation, gather information, and finally reach conclusions based on evidence. However, this instruction style is rarely used in the classroom, particularly in elementary classrooms. This study examines the relationships …

The Introduction Of Proof In Secondary Geometry Textbooks, Samuel Otten, Lorraine Males, Nicholas J. Gilbertson

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

Explicit reasoning-and-proving opportunities in the United States are often relegated to a single secondary geometry course. This study analyzed the reasoning-and-proving opportunities in six U.S. geometry textbooks, giving particular attention to the chapter that introduced proof. Analysis focused on the types of reasoning-and-proving activities expected of students and the type of mathematical statement around which the reasoning-and-proving took place, be it general or particular. Results include the fact that reasoning-and-proving opportunities in student exercises were predominantly of the particular type, whereas textbook exposition most commonly had general statements. Within the chapters introducing proof, opportunities for students to develop proofs were …
