Teacher's Toolkit: Differentiating Inquiry, Brooke A. Whitworth, Jennifer L. Maeng, Randy L. Bell

Publications

Differentiated instruction and teaching science as inquiry are two pedagogical approaches frequently discussed among science teachers. Teachers know these approaches are important but often have difficulty translating them into their classroom science instruction. This article describes how to differentiate a density investigation for variations in student readiness by varying the level of inquiry using an approach that is easily translated to experiments in any science content area.

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 …

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 …

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 …

Scientific Argumentation As A Foundation For The Design Of Inquiry-Based Science Instruction, A. Falk, L. Brodsky

Journal of Mathematics and Science: Collaborative Explorations

Despite the attention that inquiry has received in science education research and policy, a coherent means for implementing inquiry in the classroom has been missing [1]. In recent research, scientific argumentation has received increasing attention for its role in science and in science education [2]. In this article, we propose that organizing a unit of instruction around building a scientific argument can bring inquiry practices together in the classroom in a coherent way. We outline a framework for argumentation, focusing on arguments that are central to science—arguments for the best explanation. We then use this framework as the basis for …

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 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 …

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 …

Investigating Latina/O Mathematics Students' Perceptions Of Interpersonal Relationships In College Mathematics, Victoria Rose Larabell

Open Access Theses

It is known that interpersonal relationships are significant to the success of the Latina/o mathematics learner. Unfortunately, interpersonal relationships in mathematics are understudied. For this reason, this study seeks to answer the following question: How do Latina/o mathematics students perceive their interpersonal relationships with their mathematics professors, peers in mathematics, and families with respect to mathematics? To explore the role of such relationships in Latinas/os experiences in mathematics, I define a meaningful relationship in mathematics education (MRIME) as interactions between two parties in which one party acknowledges the other party as a sociocultural being and fosters their mathematics identity. This …
