Transformations In Matter And Energy: Student Learning And Inquiry To Inform Teaching, Jenny Dauer

Discipline-Based Education Research Group Speaker Series

Learning progressions are descriptions of increasing levels of sophistication of student reasoning about a topic based on empirical evidence. Our learning progression framework about student explanations of carbon-transforming processes (e.g. photosynthesis, cellular respiration) describes how student’s interconnected and mutually supporting ideas and practices are deeply embedded in discourse at all levels of achievement. My research is in two areas: 1) applying the learning progression framework for student explanations of carbon-transforming processes to describe the most productive pathways for student learning, 2) extending the research to student reasoning during inquiry activities about carbon-transforming processes. One finding is that students who consistently …

Can The Differentiated Math Classroom Be A Reality?, Carl Jeff Morris Sep 2013

Can The Differentiated Math Classroom Be A Reality?, Carl Jeff Morris

Mathematics Graduate Theses

Imagine a math classroom that looked more like a Google workplace where collaboration, teamwork, and innovation are the centerpieces. Instead of just students sitting in rows passively learning about the nature of mathematics, picture a classroom of students in small circle discussing mathematics. This could range from groups working together on a problem solving strategy for a newly learned concept, students helping students using technology as an aid, another small group receiving intervention from the teacher, or individual students making or viewing instructional math videos. All of this according to research focused on classroom differentiation; specifically in middle school and …

Exploring The Mathematical Knowledge For Teaching Of Japanese Teachers, Ratu Jared R. T. Bukarau Aug 2013

Exploring The Mathematical Knowledge For Teaching Of Japanese Teachers, Ratu Jared R. T. Bukarau

Theses and Dissertations

In the past two decades there has been an increased effort to understand the depth to which mathematics teachers must know their subject to teach it effectively. Researchers have termed this type of knowledge mathematical knowledge for teaching (MKT). Even though recent studies have focused on MKT, the current literature on the subject indicates that this area remains underdeveloped. In an attempt to further refine our conception of MKT this study looked at MKT in Japan. In this thesis I explored and categorized the MKT of three experienced Japanese cooperating teachers (CTs) by looking at the content of their conversations …

Jellyfish Identification And Quantification In The San Francisco Estuary, Amalia Borson, Lindsay L. Sullivan, Wim Kimmerer

STAR Program Research Presentations

As potential predators and competitors of plankton-eating fish, jellyfish have the potential to negatively impact fish populations. Jellyfish were collected weekly with plankton tows from the RombergTiburonCenterpier in Tiburon, CA. Since some jellyfish were too small to identify, one tow was collected and preserved to record abundances, and a second tow was collected to rear jellyfish until distinguishing characteristics were visible enough for identification. Jellyfish in the preserved tows were then identified, measured, and counted, and their abundance (number m-3) was calculated. Jellyfish from the second tows were reared in plastic buckets that were lightly bubbled using aquarium …

Detection Of Salmonella Enterica, Escherichia Coli O157 And Listeria Monocytogenes Through Bead Based Magpix® Fluidics, Karamveer Singh, Francisco Fernandez, Sonam Sahni, Alejandro Calderón-Urrea

STAR Program Research Presentations

The research is testing the limits of detection and multiplexing with the use of three pathogens with the machine created from Luminex called Magpix. The pathogens are Salmonella enterica, Listeria monocytogenes, and Escherichia Coli O157. The gene that is being focused on for each pathogen is invA for Salmonella, hlyA for listeria, and hlyA for Escherichia Coli. In this research, we started with prepared probes that were attached to the magnetic microsphere beads. Then we extracted and amplify the DNA. Furthermore, the probes were combined to the amplified DNA and used this in Magpix which gave a corresponding MFI value.
