Examining Formative Assessment Practices for English Language Learners in Science Classrooms (Collaborative Research: Li)
This is an exploratory study to identify critical aspects of effective science formative assessment (FA) practices for English Language Learners (ELLs), and the contextual factors influencing such practices. FA, in the context of the study, is viewed as a process contributing to the science learning of ELLs, as opposed to the administration of discrete sets of instruments to collect data from students. The study targets Spanish-speaking, elementary and middle school students.
LOCUS: Levels of Conceptual Understanding in Statistics
LOCUS (Levels of Conceptual Understanding in Statistics) is an NSF Funded DRK12 project (NSF#118618) focused on developing assessments of statistical understanding. These assessments will measure students’ understanding across levels of development as identified in the Guidelines for Assessment and Instruction in Statistics Education (GAISE). The intent of these assessments is to provide teachers and researchers with a valid and reliable assessment of conceptual understanding in statistics consistent with the Common Core State Standards (CCSS).
Using Rule Space and Poset-based Adaptive Testing Methodologies to Identify Ability Patterns in Early Mathematics and Create a Comprehensive Mathematics Ability Test
This project will develop a new assessment for children ages 3-7 to provide teachers with diagnostic information on a child's development of mathematics facility on ten domains such as counting, sequencing, adding/subtracting, and measurement. The Comprehensive Research-based Mathematics Ability (CREMAT) is being developed using innovative psychometric models to reveal information about children on specific attributes for each of the 10 domains.
Iterative Model Building (IMB): A Program for Training Quality Teachers and Measuring Teacher Quality
This project aims to improve professional development programs for pre-service teachers (PSTs) as a way to improve student learning in mathematics and science. PSTs engage in a series of teaching cycles, and then engage in lesson study groups to develop, teach, and analyze a whole-class lesson. The cycle is completed by reexamining students' knowledge in teaching experiments with pairs of students. These teaching cycles are called Iterative Model Building (IMB).
Diagnostic E-learning Trajectories Approach (DELTA) Applied to Rational Number Reasoning for Grades 3-8
This project aims to develop a software diagnostic tool for integrating diagnostic interviews, group administered assessments, and student data in real-time so that teachers can enter and view student status information. This project would concentrate on rational number learning in grades 3-8. The design is based on a model of learning trajectories developed from existing research studies.
Mathematics Instruction Using Decision Science and Engineering Tools
A collaboration among educators, engineers, and mathematicians in three universities, this project is creating, implementing, and evaluating a one-year curriculum for teaching a non-calculus, fourth-year high school mathematics course and accompanied assessment instruments. The curriculum will draw on decision-making tools that include but go well beyond linear programming, to enhance student mathematical competence (particularly solving multi-step problems), improve students' attitudes toward mathematics, and promote states' adoption of the curriculum (initially NC and MI).
Chemistry Facets: Formative Assessment to Improve Student Understanding in Chemistry
This project implemented a facets-of-thinking perspective to design tools and practices to improve high school chemistry teachers' formative assessment practices. Goals are to identify and develop clusters of facets related to key chemistry concepts; develop assessment items; enhance the assessment system for administering items, reporting results, and providing teacher resource materials; develop teacher professional development and resource materials; and examine whether student learning in chemistry improves in classes that incorporate a facet-based assessment system.
SAVE Science: Situated Assessment Using Virtual Environments for Science Content and Inquiry
The SAVE Science project is creating an innovative system using immersive virtual environments for evaluating learning in science, consistent with research- and policy-based recommendations for science learning focused around the big ideas of science content and inquiry for middle school years. Motivation for this comes not only from best practices as outlined in the National Science Education Standards and AAAS' Project 2061, but also from the declining interest and confidence of today's student in science.
Undergraduate Science Course Reform Serving Pre-service Teachers: Evaluation of a Faculty Professional Development Model
This project focuses on critical needs in the preparation and long-term development of pre-service, undergraduate, K-6 teachers of science. The project investigates the impact on these students of undergraduate, standards-based, reform entry level science courses developed by faculty based on their participation in the NASA Opportunities for Visionary Academics processional development program to identify: short-term impacts on undergraduate students and long-term effects on graduated teachers; characteristics of reform courses and characteristics of effective development efforts.
Design and Use of Illustrations in Test Items as a Form of Accommodation for English Language Learners in Science and Mathematics Assessment
This project investigates how vignette illustrations minimize the impact of limited English proficiency on student performance in science tests. Different analyses will determine whether and how ELL and non-ELL students differ significantly on the ways they use vignettes to make sense of items; whether the use of vignettes reduces test-score differences due to language factors between ELL and non-ELL students; and whether the level of distance of the items moderates the effectiveness of vignette-illustrated items.
