Obstacles To Developing Digital Literacy On The Internet In Middle School Science Instruction, Jamie Colwell, Sarah Hunt-Barron, David Reinking

Teaching & Learning Faculty Publications

Obstacles, and instructional responses to them, that emerged in two middle school science classes during a formative experiment investigating Internet Reciprocal Teaching (IRT), an instructional intervention aimed at increasing digital literacy on the Internet, are reported in this manuscript. Analysis of qualitative data revealed that IRT enabled students to explain and demonstrate appropriate strategies for locating and evaluating information on the Internet when they were asked to do so. However, students did not use these strategies or they quickly abandoned them when working independently or in small groups during inquiry projects. Data revealed three obstacles that inhibited efforts to promote …

Variable Appropriation Of An Online Resource Discovery And Sharing Tool, Victor R. Lee, Mimi Recker, Tamara Sumner

Instructional Technology and Learning Sciences Faculty Publications

Even when following best practices for participatory design, the appropriation of tools in formal education settings can be hampered by a number of factors. Drawing from a case of a web tool built to help teachers in five school districts find and share free resources in an educational digital library, we describe patterns of tool use and provide some explanations for variability in tool appropriation. We also suggest that future research consider school districts as complex systems of professionals whose interactions and inter-relationships may yield unexpected technology adoption behaviors.

Horizon Content Knowledge In The Work Of Teaching: A Focus On Planning, Nick Wasserman, Julianna Connelly Stockton

Mathematics Faculty Publications

Horizon content knowledge, one component of Ball et al.’s mathematical knowledge for teaching framework (e.g., Ball, Thames, & Phelps, 2008), has yet to reach adequate clarity and consensus in the field. Recently, various scholars have worked to further conceptualize and describe the mathematical horizon (e.g., Jakobsen, Thames & Ribeiro, 2013; Figueiras et al., 2011; Zazkis & Mamolo, 2011). In this communication, we identify some limitations in the ways such knowledge has thus far been described and offer an additional form of potential impact of horizon content knowledge on the work of teaching.

Minority Women In Stem: A Valuable Resource In The Global Economy, Ezella Mcpherson, Diane R. Fuselier-Thompson

Journal of the International Association for the Study of the Global Achievement Gap (Archived)

While there is an expected demographic shift of the ethnic minority population in the United States to become the majority population by 2020, few minority women successfully attain baccalaureate degrees in science, technology, engineering, and mathematical (STEM) fields. To address this gap, this article employs critical race feminism and narrative analysis methods to examine minority women’s challenges while pursuing undergraduate STEM degrees. Findings suggest that limited access to the field, isolation and alienation, and affordability create barriers that result in many minority women leaving STEM majors. Implications for practice include targeted institutional efforts to increase recruitment and retention efforts towards …

Differences Between Concrete And Virtual Manipulatives In Preparing Tenth Grade Math Students For Standardized Tests, John G. Pappas

Theses, Dissertations and Culminating Projects

Research has suggested that the use of manipulatives may enhance students’ grasp of mathematical concepts. Manipulatives may be concrete (physical) objects or virtual computer-based images of objects similar to their three-dimensional counterparts. Studies with elementary and middle-school students generally have found virtual manipulatives to outperform concrete manipulatives in enhancing students’ conceptual understanding of mathematics. However, very little research on manipulative use has been conducted with secondary school students. Furthermore, few studies have investigated instruction using virtual or concrete manipulatives across more than one content area.

This study assessed the impact of virtual and concrete manipulatives in a group of 164 …

Integrating Movement And Science To Promote Physical Activity And Academic Performance In Middle School Children, Kevin E. Finn, Kyle Mcinnis

Health Sciences Faculty Publications

Background: Recommendations from leading U.S. health agencies concerned with reducing childhood obesity call for increased physical activity during school and afterschool environments. Methods: We developed the Active Science curriculum, which is a variety of activity-based lessons (e.g., nature hike, dance class, walk at local park, treadmill at local YMCA) and incorporated them into traditional science classes and after school programs for middle school children in a low-income, ethnically diverse community. Following the activity experiments, students and teachers uploaded data from devices to an interactive website that provided inquiry-based exploratory learning of science content. Results: Physical activity results showed that the …

Improving Classroom Discourse In Inquiry-Based Primary Science Education, Prudence Smith

Theses: Doctorates and Masters

Teachers‟ capacity to use classroom discourse to deepen student learning through sustained conversation is considered crucial to increasing students‟ intellectual development. Learners actively construct knowledge and develop understandings from their shared experiences and via interaction with others (Driver, Asoko, Leach, Mortimer & Scott, 1994). However, talk that fosters students‟ capacity to reason is lacking in many classrooms (Alexander, 2006) and, what is more, teachers tend to control the discourse by asking a predominance of closed questions and using a question-answer recitation script which limits the exploration of students‟ ideas (Nystrand, Gamoran, Kachy, & Prendergast, 1997). The purpose of this study …

Numeracy Support For Year Two Students, Gillian Dawn Hurle

Theses: Doctorates and Masters

Research of teaching theories and intervention programs internationally and in Australia suggests that the implementation of numeracy support programs can improve student achievement levels (Fuchs, 2005; Ketterlin-Geller, Chard & Fien, 2008; Van Kraayenoord & Elkins, 2004). An intervention program was conducted for a small group of Year Two students with the aim of improving their numeracy skills over a 20 week period. Results of two mathematics assessments, together with information provided by teachers based on classroom observations and informal assessments were combined to select a group of twelve students who were considered to be at risk of developing mathematical difficulties. …

Reimagining The Liberal Arts In An Age Of Technoscientific Progress, Melanie Moore Watson

College of Graduate Studies: Theses & Dissertations

The following study will investigate the impact of dismantling liberal arts curriculum during an era of dramatic technoscientific progress. I will explore the development of the posthuman focusing specifically on the areas of virtual reality and biomedicine. As I unravel the implications that virtual reality and biomedicine will have on society in the coming decades, I will describe how a new liberal arts curriculum must be entertained by educators in order to maintain innovation, play, and ethical considerations in posthuman developments. In order for our students to become contributing members of a global community, they must be given the opportunity …

Knowledge, Attitudes And Practices Of Environmental Justice In Higher Education, Marjorie M. Nussbaum

College of Graduate Studies: Theses & Dissertations

Research suggests that issues of environmental justice are not being routinely included in the curriculum of the K-12 classroom and that teachers in those grades do not feel prepared to teach it. Likewise, little has been written about the addition of these topics to higher education coursework, leaving the question of inclusion at this level of education as well. This apparent lacuna may point to at least one reason why K-12 teachers are neither knowledgeable about environmental justice nor prepared to teach it. To discover the current state of inclusion in higher education, a mixed methods study was conducted to …

An Investigation Of Palindromes And Their Place In Mathematics, Ryan Andrew Nivens

ETSU Faculty Works

What do the Honda Civic, the Mazda 626, and the Boeing 747 have in common? What about Weird Al's song Bob, the first name of Miley Cyrus' alter ego, and the 70s sensation Abba? What do all these things have in common? They all contain palindromes. While some people recognise a palindrome when they see one, fewer realise that a palindrome is a special case of a pattern and that these patterns are all around. Palindromes frequently occur in names, both of vehicles and people, and in music.

Connected Mathematics Learning And Gender Equity In Predominantly Latino/A High Schools: Case Of Spatial Reasoning, Raymond Falcon

Open Access Theses & Dissertations

This study analyzed interventions used in improving the mathematics achievement in spatial reasoning tasks for females called connectedness. Gender achievement in mathematics has been a controversial topic because of the wide variance in research. Some research has found a difference between the genders in mathematics while others argue there is no difference in mathematical achievement. The Seven Clever Piece Tangrams were used in the mixed method study as the instrument of spatial reasoning tasks. Freshmen participants (N=719) from southwest high schools in a border town participated in one of two groups: control (n=247) and treatment (n=472). Of the participants, 379 …

A Comparative Analysis Of Point-Of-View Modeling For Industrial And Technology Education Courses, Petros J. Katsioloudis, Todd D. Fantz, Millie Jones

STEMPS Faculty Publications

(First paragraph): Enrollment in technology education at the college level has been declining (Isbell & Lovedahl, 1989; Volk, 1997; Daugherty, 1998; Hill, 1999; Ndahi & Ritz, 2003; Moye, 2009). It is essential for technology teacher educators to investigate ways to increase the enrollment in their programs, or the profession may fail to provide technology teachers in the future (Ndahi & Ritz, 2003). A solution that several institutions with technology education programs have adopted is the offering of the program via distance learning. Distance learning “allows participants to collapse time and space” (Cole, 2000, p. ix). According to Flowers (2003) technology …

Complexity Of Affective Disposition And Reflective Transphenomenality: An Exploratory Study Of Middle School Mathematics Teacher And Student Self-Positioning And Positioning-By-Others Toward Mathematics, Mathematics Teaching, And Learning, Ruby Lorilee Lynch-Arroyo

Open Access Theses & Dissertations

The purpose of the mixed methods study was to examine the phenomenon of transphenomenal simultaneity between teacher and student disposition that contributed to the phenomenological conflict of teacher self-positioning and positioning-by-others toward mathematics, mathematics teaching and learning. The intent was to provide a view of self-reported and observed middle school teacher and student experiences in mathematics, based on the analysis of affective dispositional characteristics within the context of its complexity.

There is evidence that documents a relationship between teacher and student disposition, but to what extent and encompassing what characteristics and factors has not been sufficiently substantiated. Beyers (2011) identified …

Investigating The Validity Of A Survey Intended To Gauge Mathematics Problem-Solving Disposition Along The Impulsive-Analytic Dimension, Miguel Mendoza

Open Access Theses & Dissertations

This study investigates the validity of the Likelihood-to-Act (LtA) survey developed to assess respondents' problem-solving disposition along the impulsive-analytic dimension. Sixteen pre-service teachers were strategically selected from a pool of 495 LtA survey respondents to participate in a semi-structured task-based interview approximately one hour in length. The interview consisted of three main parts: a problem solving section, a consistency section, and a classification section.

* Part 1 of the interview was developed to get interviewees to solve five open-response problems meant to elicit an impulsive response. Interviewees were also asked to verbalize their thought process in order for the researchers …

Identifying Most Significant Predictors Of Low Mathematics Achievement In African American Male Middle School Students, Kelley Adams

Theses and Dissertations

Research has shown that African American males have been singled out due to the fact most local and national data of academic achievement finds the group to underachieve significantly (Garibaldi, 2007). The purpose of this study is to examine variables which significantly predict lower levels of math achievement in regards to African American males. This study also examines variables that predict low math achievement for African American males to determine the most significant of the predictors. This quantitative case study includes sixth, seventh, and eighth grade African American male subjects from a middle school in the Southeast. Socioeconomic status, attendance, …
