Where Is Earth Science? Mining For Opportunities In Chemistry, Physics, And Biology, Julie Thomas, Toni Ivey, Jim Puckette

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

The Earth sciences are newly marginalized in K–12 classrooms. With few high schools offering Earth science courses, students’ exposure to the Earth sciences relies on the teacher’s ability to incorporate Earth science material into a biology, chemistry, or physics course. “G.E.T. (Geoscience Experiences for Teachers) in the Field” is an exploratory program funded by the National Science Foundation aimed to increase teachers’ geoscience interest and content knowledge. Participant teachers (n = 7) included non–Earth science teachers from underrepresented groups and/or high schools with a high percentage of students from underrepresented groups. A variety of quantitative and qualitative measures assessed …

The Development Of A Model Of Culturally Responsive Science And Mathematics Teaching, Cecilia M. Hernandez, Amanda Morales, Gail Shroyer

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

This qualitative theoretical study was conducted in response to the current need for an inclusive and comprehensive model to guide the preparation and assessment of teacher candidates for culturally responsive teaching. The process of developing a model of culturally responsive teaching involved three steps: a comprehensive review of the literature; a synthesis of the literature into thematic categories to capture the dispositions and behaviors of culturally responsive teaching; and the piloting of these thematic categories with teacher candidates to validate the usefulness of the categories and to generate specific exemplars of behavior to represent each category. The model of culturally …

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 …

The Processes Of Change On Learning Literacy And Numeracy In South Australian Primary Schools, I Gusti Ngurah Darmawan, Carol Aldous

Shannon Research Press

Success in science and mathematics is predicated on successful literacy and numeracy learning. Yet schools and communities across the country struggle to negotiate factors that both impede and facilitate such learning - particularly factors over which they have some control. Working with data more comprehensive than that used previously and applying statistical methods only recently developed, researchers from the South Australian hub of the centre for Science, Information and Communication Technology and Mathematics Education for Rural and Regional Australia (SiMERR-SA) seek answers to three basic questions. What factors influence performance in Literacy and Numeracy? Does living in a rural and …

The Relationship Between Double Dosing And Middle School Math Student Achievement, Jon Franco

Doctor of Education (EdD)

This study examined the following research question: Is there a significant difference in math performance between the total sample of below grade level 6th, 7th, and 8th grade students engaged in double dosing and the sample of below grade level 6th, 7th, and 8th grade students not engaged in double dosing? Double dosing means pulling struggling students from elective classes during the school day in favor of an extra remediation class generally in the areas of reading, writing and math. The practice of double dosing is more prevalent within the elementary schools; however, as a result of the high stakes …

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

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 …

Challenging Pre-Service Students' Teaching Perspectives In An Inquiry-Focused Program, J. L. Pecore, A. Shelton

Journal of Mathematics and Science: Collaborative Explorations

Inquiry teaching based on constructivist learning theory has been an emphasis in pre-service education for over a decade. In general, a developmental teaching perspective supports inquiry-based instruction where teachers view learners as constructors of knowledge and teaching as providing questions, problems, and challenges that form a bridge from the learners' prior knowledge to a new, more sophisticated form of reasoning. Since teaching perspectives influence student learning, teacher effectiveness, and teacher attrition, challenging pre-service teachers to overcome experience-based convictions of a transmission perspective is necessary in teacher education. In this study, we examined the teaching perspectives of secondary, pre-service methods students …

How Does Leadership Matter? Developing And Teaching A Definition Of Hands-On Science, A Prerequisite For Effective Inquiry Teaching, D. R. Sterling

Journal of Mathematics and Science: Collaborative Explorations

This descriptive case study describes leadership skills and planning for setting clear directions by program leaders for a statewide professional development initiative to extend improvement in science teaching and learning. For science teachers and leaders in Virginia, a critical part of setting clear goals that everyone can understand is defining key science terms. One of the four key terms, "hands-on science," is defined here. Materials to develop teachers' understanding of the term for effective implementation of classroom inquiry activities are shared, along with a rubric for evaluation by and for teachers. Understanding of the term "hands-on science" is necessary before …

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.

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 …

Math Education At Its Prime?, Natalie Benet

Senior Honors Theses

Three main problems with current math education are negative mindsets toward math, the lagging comparison with advanced education in other countries, and ill-equipped teachers and school systems. The consequences of these problems have impacted math education by convincing students that they do not need to try at math, filling countless classrooms with ill-qualified teachers, and overall lowering the quality of U.S. math education compared to the education of rest of the world. In order to correct these problems and reverse the present and future consequences, the quality of math education must be increased. This can be done by changing the …

Theory Guided Professional Development In Early Childhood Science Education, Soo-Young Hong, Julia C. Torquati, Victoria J. Molfese

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

The importance of early and developmentally appropriate science education is increasingly recognized. Consequently, creation of common guidelines and standards in early childhood science education has begun (National Research Council (NRC), 2012), and researchers, practitioners, and policy makers have shown great interest in aligning professional development with the new guidelines and standard. There are some important issues that need to be addressed in order to successfully implement guidelines and make progress toward accomplishing standards. Early childhood teachers have expressed a lack of confidence in teaching science and nature (Torquati, Cutler, Gilkerson, & Sarver, in press) and have limited science and pedagogical …

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 …

Degradation Of Algal Palynomorphs On 34-Yr-Old Microscope Slides, Lynn A. Brant

Journal of the Iowa Academy of Science: JIAS

Reexamination of 34-yr-old microscope slides of palynological preparations reveals the loss and degradation of algal palynomorphs, in particular the green alga Pediastrum and the desmid Pleurotaenium. Results from this study suggest that great caution should be used when referring co archived palynological slides.

A New Plant Record For Iowa: Lactuca Hirsuta (Asteraceae), Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

A new record of a native vascular plant, Lactuca hirsuta Muhlenberg ex Nuttall var. sanguinea (Bigelow) Fernald, is reported for Iowa. A specimen was collected in 1983 by the author during a study of the Swaledale railroad prairie in Cerro Gordo County, north central Iowa (Eddy 1988). The plant was inexplicably excluded in the species catalogue when a Swaledale railroad flora was published in 1988; thus, this “new” Iowa record in 2013 was collected 30 years prior. The voucher specimen was “re-discovered” by Dr. Neil A. Harriman at the University of Wisconsin-Oshkosh (OSH), and its identification verified.

Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek

Journal of the Iowa Academy of Science: JIAS

The Soil Management Assessment Framework (SMAF) was developed to help quantify soil quality/health effects of tillage, crop rotation, and other soil management practices. Our objective was to determine if the SMAF could detect soil health differences after growing a single winter triticale (X Triticosecale Wittmack) crop. Soil samples were collected from 0 to 7.5- and 7.5 to 15- cm depth increments during the 2003 – 2004 and 2004 – 2005 growing seasons near Ames and Lewis, IA, and analyzed for several potential soil quality indicators. The SMAF analysis showed higher soil quality ratings for surface than subsurface samples. It also …

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 …

Factors Affecting The Retention Of First-Career And Second-Career Science Teachers In Urban High Schools, Rosemary C. Rak

Educational Studies Dissertations

The turnover of high school science teachers is an especially troubling problem in urban schools with economically disadvantaged students. Because high teacher turnover rates impede effective instruction, the persistence of teacher attrition is a serious concern. Using an online survey and interviews in a sequential mixed-methods approach, this study investigates the perceptions of high school science teachers regarding factors that contribute to their employment decisions. The study also compares first-career and second-career science teachers' perceptions of retention and attrition factors and identifies conditions that urban school leaders can establish to support the retention of their science teachers. A purposeful sample …

The Impact Of Interdisciplinary Project Work On Student Engagement In Mathematics Learning, Kristin Sonquist

Theses and Graduate Projects

This study examines the impact of interdisciplinary project work on student engagement in mathematics learning. Students in a multiage first and second grade classroom participated in both interdisciplinary and traditional math work. Data were collected through observation, field notes and student work and were analyzed to determine whether sfudent engagement improved during the interdisciplinary project work. Indicators of engagement were identified, and found to coincide with connection, a social context, active learning and challenge. Interdisciplinary project work was found to be likely to include those elements of engagement. Finally, embedded and standardized assessments indicated a strong correlation between interdisciplinary project …

Differentiating Math Instruction In An Elementary Classroom: Teacher Perspectives, Amy Lynn Zagaros Hoff

Theses and Graduate Projects

Classroom teachers of a diverse group of learners are presented with a conundrum: how can math curriculum be effectively presented to students in order to ensure that all students are meeting required learning targets? Research shows that whole group instructional methods do not meet the needs of struggling and gifted students. So how can teachers change instruction to promote student learning for all? The purpose of this action research was to discover effective strategies to differentiate math instruction in an elementary classroom. In this qualitative research, data were collected through five structured interviews with classroom teachers. The teachers represented grades …
