Cadre-Admin

This project will adapt and study a promising and replicable teacher professional development (PD) intervention, called Collaborative Math (CM), for use in early childhood programs. Prepared as generalists, preschool teachers typically acquire less math knowledge in pre-service training than their colleagues in upper grades, which reduces their effectiveness in teaching math. To address teacher PD needs, the project will simultaneously develop teacher content knowledge, confidence, and classroom practice by using a whole teacher approach.

This project aims to engage students in meaningful scientific data collection, analysis, visualization, modeling, and interpretation. It targets grades 9-12 science instruction. The proposed research poses the question "How do learners conceive of and interact with empirical data, particularly when it has a hierarchical structure in which parameters and results are at one level and raw data at another?"

CADRE is the resource network that supports researchers and developers who participate in DRK-12 projects on teaching and learning in the science, technology, engineering and mathematics disciplines. CADRE works with projects to strengthen and share methods, findings, results and products, helping to build collaboration around a strong portfolio of STEM education resources, models and technologies. CADRE raises external audiences’ awareness and understanding of the DRK-12 program, and builds new knowledge.

This study is based on a theoretical model that embeds engineering design within social, cultural, and linguistic activity, seeking to understand (a) how adolescent English learners draw from various linguistic, representational, and social resources as they work toward solving community-based engineering design challenges; (b) the problems they face in working on the challenges and how they seek to overcome those problems; and (c) adolescents' willingness to conceptualize themselves as future engineers.

The goal of this project is to study how the integration of an online curriculum, scientist mentoring of students, and professional development for both teachers and scientist mentors can improve student outcomes. In this project, teachers and scientist mentors will engage collaboratively in a professional development module which focuses on photosynthesis and cellular respiration and is an example of a student-teacher-scientist partnership. Teachers will use their training to teach the curriculum to their students with students receiving mentoring from the scientists through an online platform. Evaluation will examine whether this curriculum, professional development, and mentoring by scientists will improve student achievement on science content and attitudes toward scientists. The project will use mixed-methods approaches to explore potential factors underlying efficacy differences between in-person and online professional development. An important component of this project is comparing in-person professional development to an online delivery of professional development, which can be more cost-effective and accessible by teachers, especially those in rural and underserved areas.

The project continues and completes the development and refinement of an electronic Test of Early Numeracy (e-TEN) in English and Spanish, focused on number and operations for young learners. The assessment incorporates a learning trajectory approach that describes students' development of the understanding of numbers. The electronic assessment allows for the test to adapt to students' responses and incorporate games increasing children's engagement with the tasks.

This project will build and validate learning trajectories (LTs) in mathematics for fraction, ratio, and for decimal and percent to represent learning by grades 3-7 students. A system will be developed to automate data collection for field testing assessment items to determine students' attainment of proficiency levels. Three LTs will be produced and validated along with over 125 assessment items for each of these three trajectories. These assessment items will be useful for diagnosing student learning.

This project will examine the relationships among the factors that influence the implementation of the Exploring Computer Science (ECS), a pre-Advanced Placement curriculum that prepares students for further study in computer science. This study elucidates how variation in curricular implementation influences student learning and determines not only what works, but also for whom and under what circumstances.

This project will design, develop, and test an online collaborative learning environment where students and teachers solve mathematical problems and communicate their thinking.  This online collaborative learning environment will help increase the quality and quantity of math discourse among mathematics teachers and students.  The researchers will also examine the impact of the online collaborative learning environment on students' significant mathematical discourse and achievement.

In response to the critical need for scholars with deep content knowledge in chemistry and the specialized training to conduct CER, this capacity building project prepares scholars whose research marries expertise in instrument design with extensive literature on chemistry misconceptions, resulting in the development of concept inventories as reliable and valid measures of student learning for use by chemistry teachers (both high school and post-secondary) and chemistry education researchers.

This project will develop a cross-platform mathematics tutoring program that addresses the problem-solving skill difficulties of second- and third-grade students with learning disabilities in mathematics (LDM). COMPS-A is a computer-generated instructional program focusing on additive word problem solving; it will provide tutoring specifically tailored to each individual student's learning profile in real time. 

The University of South Florida is hosting a conference on Research on the Enacted K-12 Mathematics Curriculum. The purpose of the conference is to explicate the theory on mathematics curriculum enactment, defining key constructs and explaining how they are expected to interact, and why, in order to facilitate the systematic accumulation of knowledge about mathematics curriculum enactment that can guide policy and practice.

The Service, Teaching, and Research (STaR) Project supports networking of early career professionals in mathematics education in higher education. Summer conferences and academic year networking allow time for trust and collegiality to develop, and thereby provide opportunities for important issues/challenges to be identified and addressed. This sustained effort promotes networking, constructs an environment that allows working research groups to be established, and provides time for significant professional growth and leadership capacity to flourish.

This project is developing inquiry-based, lab-focused, online Climate Change EarthLabs modules as a context for ongoing research into how high school students grasp change over time in the Earth System on multiple time scales. This project examines the challenges to high-school students' understanding of Earth's complex systems, operating over various temporal and spatial scales, and by developing research-based insights into effective educational tools and approaches that support learning about climate change and Earth Systems Science.

This project will design, develop, and examine the learning outcomes of a new curriculum unit for biology that embodies the conceptual framework of the Next Generation Science Standards (NGSS). The curriculum materials to be developed by this project will focus on two areas of study that are central to the life sciences: genetics and the processes of evolution by natural selection.
