Full Description: 

The primary goal of this project is to help middle school students deepen and communicate their understanding of mathematics. The project will develop and test a digital platform for middle school mathematics classrooms. The digital platform will allow students to collaboratively create representations of their mathematics thinking, incorporate ideas from other students, and share their work with the class. The digital learning environment makes use of a problem-centered mathematics curriculum that evolved from extensive development, field-testing and evaluation, and is widely used in middle schools. The research will also contribute to understanding about the design and innovative use of digital resources and collaboration in classrooms as an increasing number of schools are drawing on these kinds of tools. 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.

The project will support students to collaboratively construct, manipulate, and interpret shared representations of mathematics using digital inscriptional resources. The research activities will significantly enhance our understanding of student learning in mathematics in three important ways. The project will report on how (1) evidence of student thinking is made visible through the use of digital inscriptional resources, (2) student inscriptions are documented, discussed, and manipulated in collaborative settings, and (3) students' conceptual growth of big mathematical ideas grows over time. An iterative design research process will incorporate four phases of development, testing and revision, and will be conducted to study student use of the digital learning space and related inscriptional resources. Data sources will include: classroom observations and artifacts, student and teacher interviews and surveys, student assessment data, and analytics from the digital platform. The process will include close collaboration with teachers to understand the implementation and create revisions to the resources.

Full Description: 

The goal of this project is to develop resources and a professional development model to help early-elementary teachers improve science instruction among young learners by cultivating scientific discourse. A central component of the Next Generation Science Standards (NGSS) is engaging students in discourse with a focus on formulating and communicating scientific explanations. This project will develop a classroom observation tool that will help teachers examine changes in the quantity and quality of science discourse in K-2 classrooms over time. The project will also develop an online professional development (PD) model that uses the new observation tool to help teachers analyze their own classroom practices and the practice of others to improve classroom efforts to foster improved scientific discourse.

This early stage design and development study will employ a Design-Based Implementation Research (DBIR) approach to develop the new classroom observation tool and online professional development model, and then seek answers to the following research questions: 1) How can a classroom observation measure be developed to effectively capture the range in quality of science discourse in early elementary classrooms?; 2) How can an online PD model be developed based on the new observation tool?; 3) How do teachers' knowledge and instructional practice change over the course of participation in the yearlong PD?; and 4) How does the quantity and quality of science discourse change in K-2 classrooms over the course of teachers' participation in a yearlong online PD experience that is built around the new observation tool? The project will engage 36 teachers and their 36 different classrooms in Michigan and use multiple data sources to understand whether and how teacher knowledge and instructional practices change during participation in the new PD model. Multiple iterations of design, data collection, and refinement will be used to understand how, when, and why features of the PD and observation tool might combine to transform science discourse in early elementary classrooms. In years 3 and 4, the project team will conduct two year-long implementation trials with cohorts of 15 teachers and 5 instructional coaches (experienced science teachers) who will use the PD and tool in order study their implementation and make iterative improvements. The project will also gather data to understand changes in teacher knowledge and practice as well as video data to document changes in classroom discourse.

Full Description: 

This is an early-stage design and development collaborative study submitted to the assessment strand of the Discovery Research PreK-12 (DRK-12) program, in response to Program Solicitation NSF 15-592. The fundamental purpose of this project is to support teacher practice and professional learning around oral scientific argumentation in order to improve the quality of this practice in classrooms. To achieve this purpose, the project will examine the validity of a new technology-based formative assessment tool for classroom argumentation--"Diagnosing the Argumentation Levels of Groups" (DiALoG)--for which psychometric validation work has been conducted in a laboratory setting. The DiALoG assessment tool allows teachers to document classroom talk and display scores across multiple dimensions--both intrapersonal and interpersonal--for formative assessment purposes. The project will work with 6th-8th grade science teachers to monitor and support argumentation through real-time formative assessment data generated by the DiALoG instrument. DiALoG will be used in conjunction with "Amplify Science", a Lawrence Hall of Science-developed curriculum that incorporates the science practice of engaging in argument from evidence, and a suite of newly developed Responsive Mini-Lessons (RMLs), which consist of 20-30 minute instructional strategies designed to assist teachers to provide feedback to students' thinking and follow-up to argumentation episodes that the DiALoG tool identifies in need of further support. The study will allow the refinement and expansion of DiALoG and evaluation of its impact on teacher pedagogical content knowledge and formative assessment practices in widespread classroom use.

The project will address two specific research questions: (1) How can DiALoG be refined to provide a formative assessment tool for oral argumentation that is reliable, practical, and useful in middle school classrooms?; and (2) How does the use of DiALoG affect teacher formative assessment practices around evidence-based argumentation, when implementing science units designed to support oral argumentation? In order to answer these questions, the project will conduct a randomized control trial with 100 teachers: 50 will teach argumentation-focused curriculum with DiALoG, 50 will teach the same curriculum without DiALoG. Both control and treatment teachers will receive all digital and physical materials needed to teach three Amplify Science curriculum units. Treatment teachers will be provided also with the most recent version of DiALoG, including the linked RMLs, as well as support materials for using DiALoG with the Amplify curriculum. A subgroup of focus teachers (5 from the treatment group, and 5 from the control group) will be the subject of additional data collection and analysis. Three focus lessons, in which students are engaging in small-group or whole-class oral argumentation, will be selected from each of the three Amplify Science curricular units. Teacher measures for the randomized control trial will include validated instruments, such as (a) a pre- and post-assessment of teacher pedagogical content knowledge; (b) post-lesson and post-unit surveys in which teachers will self-report on their formative assessment practices; and (c) video recordings of selected lessons in the focus classrooms. In order to observe potential differences in formative assessment practices between treatment and control, protocols will be used to analyze the video recordings of focus classrooms, including (a) Reformed Teaching Observation Protocol; (b) Assessment of Scientific Argumentation inside the Classroom; and (c) Formative Assessment for Teachers and Students. The key outcome of this work will be a research-informed and field-tested prototype to improve the quality of teaching and learning argumentation in middle school science classrooms usable in different learning environments.

CAREER: Making Science Visible: Using Visualization Technology to Support Linguistically Diverse Middle School Students' Learning in Physical and Life Sciences

Full Description: 

The growing diversity in public schools requires science educators to address the specific needs of English language learners (ELLs), students who speak a language other than English at home. Although ELLs are the fastest-growing demographic group in classrooms, many are historically underserved in mainstream science classrooms, particularly those from underrepresented minority groups. The significant increase of ELLs at public schools poses a challenge to science teachers in linguistically diverse classrooms as they try to support and engage all students in learning science. The proposed project will respond to this urgent need by investigating the potential benefits of interactive, dynamic visualization technologies, including simulations, animations, and visual models, in supporting science learning for all middle school students, including ELLs. This project will also identify design principles for developing such technology, develop additional ways to support student learning, and provide new guidelines for effective science teachers' professional development that can assist them to better serve students from diverse language backgrounds. The project has the potential to transform traditional science instruction for all students, including underserved ELLs, and to broaden their participation in science.

In collaboration with eighth grade science teachers from two low-income middle schools in North Carolina, the project will focus on three objectives: (1) develop, test, and refine four open-source, web-based inquiry units featuring dynamic visualizations on energy and matter concepts in physical and life sciences, aligned with the Next Generation Science Standards (NGSS); (2) investigate how dynamic visualizations can engage eighth-grade ELLs and native-English-speaking students in science practices and improve their understanding of energy and matter concepts; and (3) investigate which scaffolding approaches can help maximize ELLs' learning with visualizations. Research questions include: (1) Which kinds of dynamic visualizations (simulations, animations, visual models) lead to the best learning outcomes for all students within the four instructional science units?; (2) Do ELLs benefit more from visualizations (or particular kinds of visualizations) than do native-English-speaking students?; and (3) What kinds of additional scaffolding activities (e.g., critiquing arguments vs. generating arguments) are needed by ELLs in order to achieve the greatest benefit? The project will use design-based research and mixed-methods approaches to accomplish its research objectives and address these questions. Furthermore, it will help science teachers develop effective strategies to support students' learning with visualizations. Products from this project, including four NGSS-aligned web-based inquiry units, the visualizations created for the project, professional development materials, and scaffolding approaches for teachers to use with ELLs, will be freely available through a project website and multiple professional development networks. The PI will collaborate with an advisory board of experts to develop the four instructional units, visualizations, and scaffolds, as well as with the participating teachers to refine these materials in an iterative fashion. Evaluation of the materials and workshops will be provided each year by the advisory board members, and their feedback will be used to improve design and implementation for the next year. The advisory board will also provide summative evaluation of student learning outcomes and will assess the success of the teachers' professional development workshops.

CAREER: Designing Learning Environments to Foster Productive and Powerful Discussions Among Linguistically Diverse Students in Secondary Mathematics

Full Description: 

The project will design and investigate learning environments in secondary mathematics classrooms focused on meeting the needs of English language learners. An ongoing challenge for mathematics teachers is promoting deep mathematics learning among linguistically diverse groups of students while taking into consideration how students' language background influences their classroom experiences and the mathematical understandings they develop. In response to this challenge, this project will design and develop specialized instructional materials and guidelines for teaching fundamental topics in secondary algebra in linguistically diverse classrooms. The materials will incorporate insights from current research on student learning in mathematics as well as insights from research on the role of language in students' mathematical thinking and learning. A significant contribution of the work will be connecting research on mathematics learning generally with research on the mathematics learning of English language learners. In addition to advancing theoretical understandings, the research will also contribute practical resources and guidance for mathematics teachers who teach English language learners. The Faculty Early Career Development (CAREER) program is a National Science Foundation (NSF)-wide activity that offers awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education, and the integration of education and research within the context of the mission of their organizations.

The project is focused on the design of specialized hypothetical learning trajectories that incorporate considerations for linguistically diverse students. One goal for the specialized trajectories is to foster productive and powerful mathematics discussions about linear and exponential rates in linguistically diverse classrooms. The specialized learning trajectories will include both mathematical and language development learning goals. While this project focuses on concepts related to reasoning with linear and exponential functions, the resulting framework should inform the design of specialized hypothetical learning trajectories in other topic areas. Additionally, the project will add to the field's understanding of how linguistically diverse students develop mathematical understandings of a key conceptual domain. The project uses a design-based research framework gathering classroom-based data, assessment data, and interviews with teachers and students to design and refine the learning trajectories. Consistent with a design-based approach, the project results will include development of theory about linguistically diverse students' mathematics learning and development of guidance and resources for secondary mathematics teachers. This research involves sustained collaboration with secondary mathematics teachers and the impacts will include developing capacity of teachers locally, and propagating the results of this work in professional development activities.

The project materials also include information about STEM careers in sustainability to increase the relevancy of the content for students and broaden their understanding of STEM workforce opportunities. It uses summer workshops to pilot test materials and online support and field testing in four states. Outcomes include the modules, tested and revised; strategies for transfer of learning embedded in the modules; and a compendium of green jobs, explicitly related to the modules. 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. The STEM+Computing Partnerships (STEM+C) Program is a joint effort between the Directorate for Education & Human Resources (EHR) and Directorate Computer & Information Science & Engineering (CISE). Reflecting the increasing role of computational approaches in learning across the STEM disciplines, STEM+C supports research and development efforts that integrate computing within one or more STEM disciplines and/or integrate STEM learning in computer science; 2) advance multidisciplinary, collaborative approaches for integrating computing in STEM in and out of school, and 3) build capacity in K-12 computing education through foundational research and focused teacher preparation

The project is a full design and development project in the learning strand of DRK-12. The goal is to enhance transfer of knowledge in mathematics and science via sustainability tasks with an emphasis on mathematical and scientific practices. The research questions focus on how conceptual representations and the modules support students' learning and especially transfer to novel problems. The project design integrates the research with the curriculum development. It includes a mixed methods data collection and analysis from teachers and students (e.g., interviews, content exams, focus groups, implementation logs). Assessment of student work includes both short, focused problems in the content area and longer project-based tasks providing a range of assessments of student learning. The investigators will develop a rubric for scoring student work on the tasks. The curriculum design process includes iterations of the modules over time with feedback from teachers and using data collected from the implementation.

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. 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.

The 3-year exploratory project, Conceptual Model-based Problem Solving: A Response to Intervention Program for Students with Learning Difficulties in Mathematics, 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). While mathematics problem-solving skills are critical in all areas of daily life, many students with LDM do not acquire key math concepts such as additive and multiplicative reasoning in a proficient manner during the early school years. In fact, about 5-10% of school-age children are identified as having mathematical disabilities which might cause them to experience considerable difficulties in the upper grades and experience persistent academic, life, and work challenges. Despite the proliferation of web-based mathematical games for early learners, there are very few programs or tools that target growth in the conceptual understanding of fundamental mathematical ideas, which is essential in enabling young students with LDM to perform proficiently in mathematical and everyday contexts. 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. COMPS-A will also make the reasoning and underlying mathematical model more explicit to them, and the tool's flexibility will facilitate group or one-on-one instruction in regular classroom settings, in other sessions during or after the school day, and at home. COMPS-A addresses a significant practical issue in today's classrooms by providing individualized and effective RtI intervention programs for students with LDM.

COMPS-A program represents a mathematical model-based problem-solving approach that emphasizes understanding and representation of mathematical relations in algebraic equations and, thus, will support growth in generalized problem-solving skills.COMPS-A will achieve the following objectives: 1) Create the curriculum content, screen design, and a teacher's manual for all four modules in the area of additive word problem solving; 2) Design and develop the cross-platform computer application that can be ported as a web-based, iPad, Android, or Windows app, and this flexibility will make the program accessible to all students; and 3) Conduct small-scale single subject design and randomized controlled trial studies to evaluate the potential of COMPS-A to enhance students' word problem-solving performance. The following research questions will be resolved: (1) What is the functional relationship between the COMPS-A program and students' performance in additive mathematics problem solving? (2) What is the teacher's role in identifying students' misconceptions, alternative reasoning, and knowledge gaps when students are not responsive to the intervention program? (3) What are the necessary instructional scaffolds that will address students' knowledge gaps and therefore facilitate the connection between students' conceptual schemes and the mathematical models necessary for problem solving in order to promote meaningful understanding and construction of additive reasoning? A functional prototype of the COMPS-A will be developed followed by a single-subject design study with a small group of students with LDM to field-test the initial program. Finally, a pretest-posttest, comparison group design with random assignment of participants to groups will then be used to examine the effects of the two intervention conditions: COMPS-A and business as usual. An extensive dissemination plan will enable the project team to share results to a wider community that is responsible for educating all students and, especially, students with LDM.

 

TRUmath and Lesson Study: Supporting Fundamental and Sustainable Improvement in High School Mathematics Teaching (Collaborative Research: Schoenfeld)

Given the changes in instructional practices needed to support high quality mathematics teaching and learning based on college and career readiness standards, school districts need to provide professional learning opportunities for teachers that support those changes. The project is based on the TRUmath framework and will build a coherent and scalable plan for providing these opportunities in high school mathematics departments, a traditionally difficult unit of organizational change.

Given the changes in instructional practices needed to support high quality mathematics teaching and learning based on college and career readiness standards, school districts need to provide professional learning opportunities for teachers that support those changes. The project will build a coherent and scalable plan for providing these opportunities in high school mathematics departments, a traditionally difficult unit of organizational change. Based on the TRUmath framework, characterizing the five essential dimensions of powerful mathematics classrooms, the project brings together a focus on curricular materials that support teaching, Lesson Study protocols and materials, and a professional learning community-based professional development model. The project will design and revise professional development and coaching guides and lesson study mathematical resources built around the curricular materials. The project will study changes in instructional practice and impact on student learning. By documenting the supports used in the Oakland Unified School District where the research and development will be conducted, the resources can be used by other districts and in similar work by other research-practice partnerships.

This project hypothesizes that the quality of classroom instruction can be defined by five dimensions - quality of the mathematics; cognitive demand of the tasks; access to mathematics content in the classroom; student agency, authority, and identity; and uses of assessment. The project will use an iterative design process to develop and refine a suite of tool, including a conversation guide to support productive dialogue between teachers and coaches, support materials for building site-based professional learning materials, and formative assessment lessons using Lesson Study as a mechanism to enact reforms of these dimensions. The study will use a pre-post design and natural variation to student the relationships between these dimensions, changes in teachers' instructional practice, and student learning using hierarchical linear modeling with random intercept models with covariates. Qualitative of the changes in teachers' instructional practices will be based on coding of observations based on the TRUmath framework. The study will also use qualitative analysis techniques to identify themes from surveys and interviews on factors that promote or hinder the effectiveness of the intervention.

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. This project scales up the PBS NewsHour Student Reporting Labs (SRL), a model that trains teens to produce video reports on important STEM issues from a youth perspective. Participating schools receive a SRL journalism and digital media literacy curriculum, a mentor for students from a local PBS affiliate, professional development for educators, and support from the PBS NewsHour team. The production of news stories and student-oriented instruction in the classroom are designed to increase student learning of STEM content through student-centered inquiry and reflections on metacognition. Students will develop a deep understanding of the material to choose the best strategy to teach or tell the STEM story to others through digital media. Over the 4 years of the project, the model will be expanded from the current 70 schools to 150 in 40 states targeting schools with high populations of underrepresented youth. New components will be added to the model including STEM professional mentors and a social media and media analytics component. Project partners include local PBS stations, Project Lead the Way, and Share My Lesson educators.

The research study conducted by New Knowledge, LLC will add new knowledge about the growing field of youth science journalism and digital media. Front-end evaluation will assess students' understanding of contemporary STEM issues by deploying a web-based survey to crowd-source youth reactions, interest, questions, and thoughts about current science issues. A subset of questions will explore students' tendencies to pass newly-acquired information to members of the larger social networks. Formative evaluation will include qualitative and quantitative studies of multiple stakeholders at the Student Reporting Labs to refine the implementation of the program. Summative evaluation will track learning outcomes/changes such as: How does student reporting on STEM news increase their STEM literacy competencies? How does it affect their interest in STEM careers? Which strategies are most effective with underrepresented students? How do youth communicate with each other about science content, informing news media best practices? The research team will use data from pre/post and post-delayed surveys taken by 1700 students in the STEM Student Reporting Labs and 1700 from control groups. In addition, interviews with teachers will assess the curriculum and impressions of student engagement.

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. This project will develop and test a biology teacher professional model that employs analysis of videotaped lessons to promote increased biology content knowledge and pedagogical content knowledge among practicing biology teachers. The content of the professional development activities will focus on the crosscutting concepts of stability and change that link core ideas in three areas of biology: cell biology, heredity, and evolution. These are content areas that have been shown to be difficult for students to learn, and difficult for teachers to teach. The professional development model will include: a) a summer institute where teachers gain new knowledge and skills in biology and learn to analyze videotaped lessons; b) opportunities to teach project-developed lessons during the academic year; and c) study group sessions during the academic year where participating teachers analyze videoclips of their own teaching.

The project will design, develop, and test a teacher professional development model that is based on a previously developed approach that has been shown to be effective among elementary school teachers. It is hypothesized that the newly developed program will have a positive impact on the science achievement of high school students, that it will improve teacher science content knowledge and classroom practice, and that the effects on student outcomes will be equitable across student demographic variables. To test thee hypotheses, the project will employ a quasi-experimental research approach in which teachers will serve as their own comparison groups in a cohort control design. Hierarchical linear modeling will be used to differentiate the effects of variances in teacher content knowledge and pedagogical content knowledge, student demographic variables, and school factors. It is anticipated that the project will find evidence that the proposed approach to biology teacher professional development has the potential to close the achievement gaps among student populations.
