Bridging Professional Development And Context: Integrating Mathematics And Academic Language In A District Facing Takeover, Patricia Swanson, David Whitenack
Faculty Publications
This quasi-experimental, multi-phase study uses mixed methods to evaluate a professional development initiative focused on integrating mathematics and academic language. The context is a highly diverse urban district facing state takeover. The professional development focused on the understanding of key mathematics concepts and developing content-specific academic language. It linked explicitly to district-adopted texts and prescribed lesson formats. Teachers perceived the strategies to be feasible and beneficial to student learning, and had high rates of implementation. Nonetheless, pacing guides pressuring teachers to quickly cover content pose challenges for continued implementation. Implications for (1) professional development focusing on integrating subject-matter content and …

A Proposal For A Common Minimal Topic Set In Introductory Biology Courses For Majors, Eileen Gregory, Jane P. Ellis, Amanda N. Orenstein
Faculty Publications
A common complaint among instructors of introductory biology courses is the course covers too much material. Without a national consensus specifying which topics are essential, instructors are leery of excluding material. A survey was administered to Two-Year College and Four-Year College and University section members of the National Association of Biology Teachers (NABT) to identify the topics and skills college and university biology instructors believe students completing introductory biology should know and comprehend. Analysis identified a strong consensus for twenty topics and seven skills that should be included in all year-long introductory college biology course sequences for majors.

The Oregon Mathematics Leadership Institute (OMLI) project served 180 Oregon teachers, and 90 administrators, across the K-12 grades from ten partner districts. OMLI offered a residential, three-week summer institute. Over the course of three consecutive summers, teachers were immersed in a total of six mathematics content classes– Algebra, Data & Chance, Discrete Mathematics, Geometry, Measurement & Change, and Number & Operations—along with an annual collegial leadership course. Each content class was designed and taught by a team of expert faculty from universities, community colleges, and K-12 districts. Each team chose a few “big ideas” on which to focus the course. …
Providing Preservice Teachers With Worthwhile Field-Based Experiences In Mathematics, Glenn Nelson
Providing Preservice Teachers With Worthwhile Field-Based Experiences In Mathematics, Glenn Nelson
Faculty Publications
Providing preservice teachers with worthwhile field-based experiences is recognized as an important component in their development as good teachers. Because mathematics instruction in general has moved from a teacher-directed, procedurally-focused process to a more student-centered, conceptually-oriented approach, preservice mathematics education classes – especially methods courses - should reflect this shift as well. Field-based opportunities can be instances for preservice teachers to personally experience such a shift to real-world relevance.

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell
Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell
Faculty Publications
Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.

Using technology tools in math instruction can help stimulate problem-solving skills and understanding of math concepts. However, teachers need to be confident in their abilities to use technology tools. This study investigated whether or not a four-week in-service professional development institute that addressed the use of technology in math education helped improved the teachers’ attitude and confidence in applying technology. Findings indicated that as the teachers explored and used the available technology tools relevant to math instruction during the institute, the more proactive and motivated they became to continue their professional development in using technology for classroom instruction. They realized …
Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert
Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert
Faculty Publications
Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

En los últimos años nuestras aulas de ciencias han incorporado la argumentación como una herramienta para promover la construcción de conocimiento. Un aspecto generalmente olvidado en dichas intervenciones, así como en las investigaciones de las cuales derivan, es el análisis del impacto que el objetivo de la argumentación tiene en la actividad argumentativa desplegada en las aulas. En el discurso argumentativo distinguimos dos tipos de actividad: la oposición y la deliberación. En la actividad de oposición el objetivo es mantener el punto de vista y debilitar las alternativas, mientras que en la actividad de deliberación el objetivo es consensuar un …

Meaningful Distributed Instruction— Developing Number Sense, Edward C. Rathmell
Faculty Publications
What Is Number Sense?
The primary goal for elementary and middle school mathematics is to help students learn to use numbers meaningfully, reasonably and flexibly in everyday life. This means that students must develop a deep understanding of
-- numbers and operations,
-- when operations can appropriately be used to solve problems, and
-- judging the reasonableness of their solutions to problems.
They also need to develop attitudes so they
-- believe they can make sense of mathematics, and
-- habitually try to make sense of mathematics.
In other words, students need to develop number sense.
Understandings Needed for Number …

Understanding meanings of operations and how they relate to one another is an important mathematical goal for students in fourth grade (National Council of Teachers of Mathematics, 2000). Using pictures, diagrams, or concrete materials to model multiplication helps students learn about factors and how their products represent various contexts. The foundation of understanding how operations of multiplication and division relate to one another deepens the understanding of the composition of numbers. Discussing different types of problems that can be solved using multiplication and division is important, along with the ability to decompose numbers. When students can work among these relationships …

In teaching statistical processes, it is important that there be application to realworld settings and activities. When this is done, students are more likely to see the meaning of the steps being developed.
One such activity involves using the Chi-Square statistical test and its applications to counting Skittles Chocolate Mix candies. Many students are aware that these candies come in five different flavors: Brownie Batter (BB), Vanilla (V), Chocolate Caramel (CC), S’mores (S), and Chocolate Pudding (CP).

I am fortunate. I teach from Investigations in Number, Data, and Space [TERC] (1996), a standards-based elementary mathematics curriculum. My evolution from teaching in a traditional teacher-centered approach to one that supports a student-centered community of learners has been a slow and gradual process during the past six years of teaching. Fortunately, through experience, professional development, and graduate level courses, I have come to appreciate the conceptual understanding students acquire from learning mathematics via a student-centered approach and how playing games is an effective instructional strategy for learning mathematics. As intended by the authors of Investigations and envisioned by the …

We developed activity-based instructional units to introduce basic quantum principles to students with limited physics and mathematics backgrounds. To emphasize the practical applications of contemporary physics, we introduced concepts using the contexts of light-emitting devices such as light-emitting diodes (LEDs), fluorescent lamps, and glow-in-the-dark toys. As our standard of living becomes more dependent on the latest developments in science and technology, our students' literacy must be at a level that enables them to make educated decisions on science- and technology-related issues and their everyday applications. Students need to have at least a basic understanding of 20th-century physics and its applications …

Sol-Gel Phase Transitions In Thermoreversible Gels: Onset Of Gelation And Melting, Y. Liu, R.B. Pandey
Faculty Publications
A Monte Carlo simulation model is propsed to study the phase transition and the structural evolution of thermoreversible gels with the coexistence of phase separation and gelation processes. Our model includes the mobility of all the species and the reversibilty of bonds of the clusters formed due to cross-linking reactions. These features provide a more realistic depiction of a polymer-solvent system. We attempt to elucidate the effects of interactions, solvents, polymer fraction, etc. on the phase behaviors of the thermoreversible gel. Sol-to-gel transition is studied in detail as a function of temperature, and the related critical exponents are evaluated. Two …
