Full Description: 

Students with disabilities often have fewer opportunities for experiential learning, an important component of quality STEM education. With continued shifts toward the use of digital media to supplement instruction in STEM classrooms, much of the content remains inaccessible, particular for students with visual impairments. The promise of technology and use of tactile graphics is an effective, emerging innovation for providing more complete access to important information and materials. Tactile graphics are images that use raised surfaces to convey non-textual information such as maps, paintings, graphs and diagrams. Touchscreen-based smart devices allow visual information to be digitally and dynamically represented via tactile, auditory, visual, and kinesthetic feedback. Tactile graphic technology embedded in touchscreen devices can be leveraged to make STEM content more accessible to blind and visually impaired students.

This project will develop a learner-centered, perceptually-motivated framework addressing the requirements for students with blindness and visual impairments to access graphical content in STEM. Using TouchSense technology, the investigators will create instructional materials using tactile graphics and test them in a pilot classroom of both sighted and BVI students. The investigators will work with approximately 150 students with visual impairments to understand the kind of feedback that is most appropriate for specific content in algebra (coordinate plane), cell biology, and geography. Qualitative research methods will be used to analyze the video-based data set.

Full Description: 

Students with disabilities often have fewer opportunities for experiential learning, an important component of quality STEM education. Computer based simulations in science can provide valuable opportunities for these students to experience and manipulate natural phenomena related to critical STEM ideas. However, existing simulations remain largely inaccessible to students with visual impairments in particular. Recent advances in technology related to sonification use with simulations can make it possible for these students to have a more complete and authentic experience. Sonification is the use of non-speech sounds, such as musical tones, to represent visual information including data. Such sounds can be manipulated temporally and spatially and can also vary by amplitude and frequency to convey information that is more traditionally displayed visually. 

Researchers will iteratively develop five middle school physical science simulations to include sonifications aimed at enhancing accessibility for all learners, but particularly for those with visual impairments. Data collection activities will include focus groups and interviews with students and teachers focused on engagement. The end products of this project will include sonified simulations, professional development resources, design guidelines and exemplars, and publications.

InquirySpace 2: Broadening Access to Integrated Science Practices

This project will create technology-enhanced classroom activities and resources that increase student learning of science practices in high school biology, chemistry, and physics. InquirySpace will incorporate several innovative technological and pedagogical features that will enable students to undertake scientific experimentation that closely mirrors current science research and learn what it means to be a scientist.

Full Description: 

This project will create technology-enhanced classroom activities and resources that increase student learning of science practices in high school biology, chemistry, and physics courses. The project addresses the urgent national priority to improve science education as envisioned in the Next Generation Science Standards (NGSS) by focusing less on learning facts and equations and instead providing students with the time, skills, and resources to experience the conduct of science and what it means to be a scientist. This project builds on prior work that created a sequence of physics activities that significantly improved students' abilities to undertake data-based experiments and led to productive independent investigations. The goal of the InquirySpace project is to improve this physics sequence, extend the approach to biology and chemistry, and adapt the materials to the needs of diverse students by integrating tailored formative feedback in real time. The result will be student and teacher materials that any school can use to allow students to experience the excitement and essence of scientific investigations as an integral part of science instruction. The project plans to create and iteratively revise learning materials and technologies, and will be tested in 48 diverse classroom settings. The educational impact of the project's approach will be compared with that of business-as-usual approaches used by teachers to investigate to what extent it empowers students to undertake self-directed experiments. To facilitate the widest possible use of the project, a complete set of materials, software, teacher professional development resources, and curriculum design documents will be available online at the project website, an online teacher professional development course, and teacher community sites. The Discovery Research K-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models and tools (RMTs). Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for proposed projects.

InquirySpace will incorporate several innovative technological and pedagogical features that will enable students to undertake scientific experimentation that closely mirrors current science research. These features will include (1) educational games to teach data analysis and interpretation skills needed in the approach, (2) reduced dependence on reading and writing through the use of screencast instructions and reports, (3) increased reliance on graphical analysis that can make equations unnecessary, and (4) extensive use of formative feedback generated from student logs. The project uses an overarching framework called Parameter Space Reasoning (PSR) to scaffold students through a type of experimentation applicable to a very large class of experiments. PSR involves an integrated set of science practices related to a question that can be answered with a series of data collection runs for different values of independent variables. Data can be collected from sensors attached to the computer, analysis of videos, scientific databases, or computational models. A variety of visual analytic tools will be provided to reveal patterns in the graphs. Research will be conducted in three phases: design and development of technology-enhanced learning materials through design-based research, estimation of educational impact using a quasi-experimental design, and feasibility testing across diverse classroom settings. The project will use two analytical algorithms to diagnose students' learning of data analysis and interpretation practices so that teachers and students can modify their actions based on formative feedback in real time. These algorithms use computationally optimized calculations to model the growth of student thinking and investigation patterns and provide actionable information to teachers and students almost instantly. Because formative feedback can improve instruction in any field, this is a major development that has wide potential.

Sensing Science through Modeling: Developing Kindergarten Students' Understanding of Matter and Its Changes

This project will develop a technology-supported, physical science curriculum that will facilitate kindergarten students' conceptual understanding of matter and how matter changes.

Full Description: 

Despite recent research demonstrating the capacity of young children to engage deeply with science concepts and practices, challenging science curriculum is often lacking in the early grades. This project addresses this gap by developing a technology-supported, physical science curriculum that will facilitate kindergarten students' conceptual understanding of matter and how matter changes. To accomplish these goals, the curriculum will include opportunities for students to participate in model-based inquiry in conjunction with the use of digital probeware and simulations that enable students to observe dynamic visualizations and make sense of the phenomena. To support the capacity of kindergarten teachers, a continuous model of teacher development will be implemented.

Throughout development, the project team will collaborate with kindergarten teachers and more than 300 demographically diverse students across eight classrooms in Massachusetts and Indiana. A design based research approach will be used to iteratively design and revise learning activities, technological tools, and assessments that meet the needs and abilities of kindergarten students and teachers. The project team will: 1) work with kindergarten teachers to modify an existing Grade 2 curricular unit for use with their students; 2) design a parallel curricular unit incorporating technology; 3) evaluate both units for feasibility and maturation effects; and 4) iteratively revise and pilot an integrated unit and assess kindergarten student conceptual understanding of matter and its changes. The results of this investigation will contribute important data on the evolving structure and content of children's physical science models as well as demonstrate children's understanding of matter and its changes.

Strengthening Mathematics Intervention: Identifying and Addressing Challenges to Improve Instruction for Struggling Learners

This project's first goal is to study the national landscape of mathematics intervention classes, which are additional classes provided to struggling students, including learners with and without identified disabilities. We administered a survey to a nationally representative sample of 2,024 urban and suburban public schools with grades 6-8 to find out how these classes are being implemented and the types of challenges faced.

Full Description: 

Across the nation, schools face a pressing need to improve instruction for middle grades students who are not reaching proficiency on standardized assessments. One approach is to schedule additional mathematics classes to provide struggling learners with more time for instruction and support. For our study, we defined mathematics interventional classes as classes taken by struggling students during the regular school day in addition to their general education mathematics classes. These classes are for students who have difficulties learning mathematics, including learners who do not have identified disabilities and those with Individualized Education Programs (IEPs). 

While recommendations for intervention practices are present in the research literature, little is known about how schools are actually implementing intervention classes, including how often the classes meet, the number of students enrolled, who teaches them and the content focus. To address this gap in the knowledge base, we conducted an observational study and a national survey of current practices and challenges in mathematics intervention classes. The survey was administered to a nationally representative sample of 2,024 urban or suburban public schools with grades 6-8.  Approximately, 43% of schools (876 schools) responded; the findings revealed widespread implementation of mathematics intervention classes and variations in class structures and practices. 

The final aspect of the project involves the design of professional development for mathematics intervention teachers based on the needs identified in the earlier phases of the project. We are developing and testing a blended professional development course to help teachers build the knowledge and practices needed to provide high-quality, targeted instruction to struggling learners in mathematics intervention classes.

Proportions Playground: A Dynamic World to Support Teachers' Proportional Reasoning

This project focuses on the creation of the initial functionality for a dynamic microworld, Proportions Playground, designed to support teachers in developing a coherent understanding of proportional reasoning. The Proportions Playground project seeks to both develop a unique pilot software application for the iPad and explore how it supports teachers in developing a coherent, robust definition of proportions.

Full Description: 

Proportions are a critical topic in mathematics that is simultaneously complicated and over-simplified in typical instruction. Current research undertaken by the research team suggests that the over-simplification is related to limitations in teachers' understandings of proportional relationships. Presenting proportions in a dynamic environment offers teachers the opportunity to create key developmental understandings related to this area of mathematics. This project focuses on the creation of the initial functionality for a dynamic microworld, Proportions Playground, designed to support teachers in developing a coherent understanding of proportional reasoning. Proportions Playground is conceptualized as a tool for supporting the development of coherent understandings by allowing teachers to interact in concrete ways with otherwise abstract ideas and by allowing teachers easy access to dynamic objects and other representations. It is meant to address the significant limitations for reasoning about the relationships between measurable aspects of two objects as well as in manipulating those relationships. Building from work currently underway, Proportions Playground will explore key areas in which there are opportunities for engaging teachers in the development of a coherent and robust understanding of proportional reasoning that extends beyond the typical "3 given, 1 unknown" proportion problem. This approach attempts to engage teachers in an array of dynamic, visually-rich sets of tasks designed to challenge teachers' preconceptions of proportions and to strengthen their connections between proportions and related areas of mathematics. This project is funded by the Discovery Research PreK-12 (DRK-12) and EHR Core Research (ECR) Programs. the DRK-12 program supports research and development on STEM education innovations and approaches to teaching, learning, and assessment. The ECR program emphasizes fundamental STEM education research that generates foundational knowledge in the field.

The Proportions Playground project seeks to both develop a unique pilot software application for the iPad and explore how it supports teachers in developing a coherent, robust definition of proportions. The software will be designed to support either numeric manipulation (e.g., graphing software) or geometric constructions (e.g., dynamic geometry software). Specifically, for this project the mathematics of interest will include the relationships between similarity and proportion and the nature of covariation. The research will focus on how teachers are developing a robust and coherent understanding of proportions and how the dynamic environment promotes such understandings. Working with six teacher advisors, the project will develop three task sets. Using teaching experiments and individual interviews, results will be used to refine the task sets. The revised task sets will be piloted with 40 teachers. Data will be collected on participants' thinking and any changes seen in the knowledge resources they are using. The researchers will be looking for factors that seem to impact teachers' thinking as well as evidence to support or deny the assertion that the Proportions Playground activities engage teachers in (a) different ways of reasoning about proportions and (b) support them in drawing from a wide array of resources so that coherence may be developed were the teachers to have a prolonged engagement with the tools. The project will rely on Epistemic Network Analysis to identify the connections between knowledge resources.

Building a Next Generation Diagnostic Assessment and Reporting System within a Learning Trajectory-Based Mathematics Learning Map for Grades 6-8

This project will build on prior funding to design a next generation diagnostic assessment using learning progressions and other learning sciences research to support middle grades mathematics teaching and learning. The project will contribute to the nationally supported move to create, use, and apply research based open educational resources at scale.

Full Description: 

This project seeks to design a next generation diagnostic assessment using learning progressions and other research (in the learning sciences) to support middle grades mathematics teaching and learning. It will focus on nine large content ideas, and associated Common Core State Standards for Mathematics. The PIs will track students over time, and work within school districts to ensure feasibility and use of the assessment system.

The research will build on prior funding by multiple funding agencies and address four major goals. The partnership seeks to address these goals: 1) revising and strengthening the diagnostic assessments in mathematics by adding new item types and dynamic tools for data gathering 2) studying alternative ways to use measurement models to assess student mathematical progress over time using the concept of learning trajectories, 3) investigating how to assist students and teachers to effectively interpret reports on math progress, both at the individual and the class level, and 4) engineering and studying instructional strategies based on student results and interpretations, as they are implemented within competency-based and personalized learning classrooms. The learning map, assessment system, and analytics are open source and can be used by other research and implementation teams. The project will exhibit broad impact due to the number of states, school districts and varied kinds of schools seeking this kind of resource as a means to improve instruction. Finally, the research project contributes to the nationally supported move to create, use, and apply research based open educational resources at scale.
