Full Description: 

Minimal rigorous research has been conducted on the effect of various supports for quality mathematics instruction and providing guidance on the development and use of Elementary Mathematics Specialists (EMSs) on student achievement. Portland Public Schools (PPS), Portland State University, and RMC Research Corporation will study the Developing Leaders Transforming Practice (DLTP) intervention, which aims to improve teachers' instructional practices, increase student mathematics understanding and achievement. The project team will evaluate the efficacy and use of EMSs by testing four implementation models that consider the various ways EMSs are integrated into schools. DLTP builds on EMS research, investigating EMSs both as elementary mathematics teachers and coaches by articulating four models and examining their efficacy for both student and teacher learning. This study has the potential to provide benefits both within and beyond PPS as it informs the preparation and use of EMSs. Determining which model is best in certain contexts provides a focus for the expansion of mathematics support.

DLTP enhances the research base by examining the effect of teacher PD on student achievement through a rigorous quasi-experimental design. The project goals will be met by addressing 4 research questions: 1) What is the effect of the intervention on teacher leadership?; 2) What is the effect of the intervention on teachers' use of research-based instructional practices?; 3) What is the effect of the intervention on a school's ability to sustain ongoing professional learning for teachers?; and 4) What is the effect of the intervention on student mathematics achievement? Twelve elementary schools in PPS will select elementary teachers to participate in the DLTP and adopt an implementation model that ranges from direct to diffuse engagement with students: elementary mathematics teacher, grade level coach, grade-level and building-level coach, or building-level coach. The research team will conduct 4 major studies that include rigorous quasi-experimental designs and a multi-method approach to address the research questions: leadership study, instructional practices study, school study, and student achievement study. Several tools will be created by the project - a leadership rubric designed to measure changes in EMS mathematics leadership because of the project and a 5-part teacher survey designed capture EMS leadership skills, pedagogical content knowledge, use of research-based practices, and school climate for mathematics learning as well as implementation issues.

Students and Teachers Learning from Nature: Studying Biologically Inspired Design in High School Engineering Education

In this project, high school engineering teachers will spend five weeks in a research lab devoted to biologically-inspired design, as they partner with cutting-edge engineers and scientists to study animal features and behavior and their applications to engineering designs. After this lab experience, the high school teachers will receive three six- to ten-week curricular units, tailored for tenth- through twelfth-grade students, which teach biologically-inspired design in the context of problems that are relevant to youth.

Full Description: 

Scientists and engineers often learn from nature to develop new products that benefit society, a process called biologically-inspired design. Aerospace engineers, for example, have studied the intricate folding patterns in ladybugs' wings to gain ideas for designing more compact satellites. In this project, high school engineering teachers will spend five weeks in a research lab devoted to biologically-inspired design, as they partner with cutting-edge engineers and scientists to study animal features and behavior and their applications to engineering designs. After this lab experience, the high school teachers will receive three six- to ten-week curricular units, tailored for tenth- through twelfth-grade students, which teach biologically-inspired design in the context of problems that are relevant to youth. The teachers will also participate in ongoing professional development sessions that demonstrate strategies for teaching these units. The research team will study whether and how the lab and professional development experiences influence the teachers' understandings of engineering and perspectives toward nature, among other outcomes. Additionally, the research team will study whether the curricular units are associated with positive learning outcomes for students. The curricula and professional development modules will be shared publicly through online resources and teacher workshops, and research findings will be widely disseminated through journals. Because previous research has suggested that biologically-inspired design is a promising approach for attracting and retaining women in engineering careers, this project is likely to result in products that foster high school girls' interest in engineering during a critical period when they are imagining their future career trajectories. Moreover, these products are likely to fuel national innovation by teaching students how to look to nature to find answers to pressing problems, and by generating knowledge about motivational educational approaches that encourage a wider range of high school students to pursue engineering careers.

This project addresses the persistent underrepresentation of girls in engineering careers by developing and testing three sets of curricula that are expected to lead to positive outcomes among high school females. These curricula incorporate biologically-inspired engineering, humanistic engineering, a focus on sustainability and ideation, and authentic design contexts. Ten high school teachers will participate in extensive professional development experiences that prepare them to effectively teach the curricula. These experiences include a five-week lab experience with scientists who are applying biologically-inspired design; a one-week workshop demonstrating strategies for teaching the units; weekly implementation meetings; and web-based professional development modules. To study the effect of the professional development on teachers, researchers will collect curriculum design logs, teacher enactment surveys, and engineering teaching self-efficacy surveys; they will also conduct classroom observations and interviews. Qualitative analyses of these sources will indicate whether and how the professional development affected teachers' understanding of the engineering design process, engineering teaching self-efficacy, and perspective toward the natural and designed world. To study the effect of the curricula on over 1,100 high school students, researchers will use a pre-post design with validated measures to determine whether the curricula are associated with greater understanding and use of the engineering design process; ability to generate well-formulated engineering design problems; engineering self-efficacy; attitudes toward the natural and designed world; sustainability awareness; and intent to persist in engineering. Subsequently, a quasi-experimental design with a matched comparison group will enable the researchers to determine whether the treatment group outperformed the comparison group on pre-post measures. Qualitative analysis of focus groups and interviews with a sub-set of high school girls will indicate whether and how the curricula supported their sense of belonging in engineering. This project is designed to advance knowledge and practice in engineering education for high school students, especially among girls, ultimately resulting in broadening participation in engineering pathways.

Full Description: 

The Researching Order of Teaching project will provide structured and meaningful scaffolds for teachers in examining two research-based teaching strategies hypothesized to positively impact mathematics achievement in the areas of mathematical modeling and problem solving. The first strategy, Explicit Attention to Concepts (EAC), is a set of practices that draw students' attention specifically to mathematical concepts in ways that extend beyond memorization, procedures, or application of skills. This strategy may include teachers asking students to connect multiple mathematical representations, compare solution strategies, discuss mathematical reasoning underlying procedures, or to identify a main mathematical idea in a lesson and how it fits into the broader mathematical landscape. The second strategy, Student Opportunities to Struggle (SOS), entails providing students with time and space to make sense of graspable content, overcoming confusion points, stimulating personal sense-making, building perseverance, and promoting openness to challenge. This strategy may include teachers assigning problems with multiple solution strategies, asking students to look for patterns and make conjectures, encouraging and promoting discourse around confusing or challenging ideas, and asking students for extended mathematical responses. This project investigates whether the order in which teachers apply these practices within the teaching of mathematics content has an impact on student learning. This study builds on previous work that had identified an interaction between the EAC and SOS instructional strategies, and associated teacher reporting of stronger use of the practices with higher student mathematics achievement.

The project will have four key design features. First, the project will adopt and extend the research-based EAC/SOS conceptual framework, and explicitly responds to the call for further research on the interactions. Second, the project will focus on the mathematical areas of modeling and problem solving, two complex and critical competencies for all students in the middle grades. Third, the project will position teachers as collaborators in the research with needed expertise. Finally, the project will make use of research methods from crossover clinical trials to implementation in classrooms. The project aims to identify the affordances and constraints of the EAC/SOS framework in the design and development of instructional practices, to identify student- and teacher-level factors associated with changes in modeling and problem solving outcomes, to analyze teachers' implementations EAC and SOS in teaching modeling and problem solving and to associate those implementation factors with student achievement changes, and to determine whether the ordering of these two strategies correlates with differences in achievement. The project will collect classroom observation data and make use of existing tools to obtain reliable and valid ratings of the EAC and SOS strategies in action.The design of the study features a randomized 2 x 2 cluster crossover trial with a sample of teachers for 80% power. The project builds on existing state infrastructure and relationships with a wide array of school districts in the context of professional development, and aims to create a formal Teacher-Researcher Alliance for Investigating Learning as a part of the project work.

Using Animated Contrasting Cases to Improve Procedural and Conceptual Knowledge in Geometry

This project aims to support stronger student outcomes in the teaching and learning of geometry in the middle grades through engaging students in animated contrasting cases of worked examples. The project will design a series of animated geometry curricular materials on a digital platform that ask students to compare different approaches to solving the same geometry problem. The study will measure changes in students' procedural and conceptual knowledge of geometry after engaging with the materials and will explore the ways in which teachers implement the materials in their classrooms.

Full Description: 

This project aims to support stronger student outcomes in the teaching and learning of geometry in the middle grades through engaging students in animated contrasting cases of worked examples. Animated contrasting cases are a set of two worked examples for the same geometry problem, approached in different ways. The animations show the visual moves and annotations students would make in solving the problems. Students are asked to compare and discuss the approaches. This theoretically-grounded approach extends the work of cognitive scientists and mathematics educators who have shown this approach supports strong student learning in algebra. The project will design a series of animated geometry curricular materials on a digital platform that ask students to compare different approaches to solving the same geometry problem. The study will measure changes in students' procedural and conceptual knowledge of geometry after engaging with the materials and will explore the ways in which teachers implement the materials in their classrooms. This work is particularly important as geometry is an understudied area in mathematics education, and national and international assessments at the middle school level consistently identify geometry as a mathematics content area in which students score the lowest.

This project draws on prior work that documents the impact of comparison on students' learning in algebra. Providing students with opportunities to compare multiple strategies is recommended by a range of mathematics policy documents, as research has shown this approach promotes flexibility and enhances conceptual knowledge and procedural fluency. More specifically, the approach allows students to compare the effectiveness and efficiency of mathematical arguments in the context of problem solving. An initial pilot study on non-animated contrasting cases in geometry shows promise for the general approach and suggests that animating the cases has the potential for stronger student learning gains. This study will examine the extent to which the animated cases improve students' conceptual and procedural knowledge of geometry and identify factors that relate to changes in knowledge. The project team will develop 24 worked example contrasting cases based on design principles from the prior work in algebra. The materials will be implemented in four treatment classrooms in the first cycle, revised, and then implemented in eight treatment classrooms. Students' written work will be collected along with data on the nature of the classroom discussions and small-group interviews with students. Teachers' perspectives on lessons will also be collected to support revision and strengthening of the materials. Assessments of students' geometry knowledge will be developed using measures with demonstrated validity and reliability to measure changes in student learning.

Teacher Professional Learning to Support Student Motivational Competencies During Science Instruction (Collaborative Research: Linnenbrink-Garcia)

This project will bring together a multi-disciplinary team of researchers and science teachers to identify a set of practices that science teachers can readily incorporate into their planning and instruction. The project will design, develop, and test a research-based professional learning approach to help middle school science teachers effectively support and sustain student motivational competencies during science instruction.

Science teachers identify fostering student motivation to learn as a pressing need, yet teacher professional learning programs rarely devote time to helping teachers understand and apply motivational principles in their instruction. This project will bring together a multi-disciplinary team of researchers and science teachers to identify a set of practices that science teachers can readily incorporate into their planning and instruction. The project will design, develop, and test a research-based professional learning approach to help middle school science teachers effectively support and sustain student motivational competencies during science instruction. The approach will include use of materials addressing student motivational processes and how to support them, evaluation tools to measure student motivational competencies, lesson planning tools, and instruments for teacher self-evaluation. The translation to practice will include recognition of student diversity and consider ways to facilitate context-specific integration of disciplinary and motivational knowledge in practice. The project will focus on middle school science classrooms because this period is an important motivational bridge between elementary and secondary science learning. This project will enhance understanding of teacher pedagogical content knowledge (PCK) in that it frames knowledge about supporting motivational competencies in science as PCK rather than general pedagogical knowledge.

This early stage design and development project will iteratively develop and study a model of teacher professional learning that will help middle school science teachers create, modify, and implement instruction that integrates support for students' motivational competencies with the science practices, crosscutting concepts, and disciplinary core ideas specified in science curriculum standards. A design-based research approach will be used to develop and test four resources teachers will use to explicitly include attention to student motivational competencies in their lesson planning efforts. The resources will include: 1) educational materials about students' motivational processes with concrete examples of how to support them; 2) easy-to-implement student evaluation tools for teachers to gauge students' motivational competencies; 3) planning tools to incorporate motivational practices into science lesson planning; and 4) instruments for teacher self-evaluation. A collaborative group of educational researchers will partner with science teachers from multiple school districts having diverse student populations to jointly develop the professional learning approach and resources. This project will contribute to systemic change by moving motivational processes from an implicit element of educating students, to an explicit and intentional set of strategies teachers can enact. Research questions will focus on how teachers respond to the newly developed professional learning model, and how students respond to instruction developed through implementing the model.

Translating a Video-based Model of Teacher Professional Development to an Online Environment

This project will adapt an effective in-person teacher professional development model to an online approach. A defining feature of the Science Teachers Learning from Lesson Analysis (STeLLA) Professional Development program is its use of videos of classroom instruction and examples of student work to promote teacher learning. Adapting the STeLLA program to an online learning model can reach a broader and more diverse audience, such as teachers working in rural school districts and underserved communities.

Improving the quality of teaching is essential to improving student outcomes. But what are the most effective ways to support teachers' professional development?  BSCS Science Learning and the University of Minnesota STEM Education Program Area explore this question by adapting an effective teacher professional development model -- that meets face-to-face in real-time -- to an online approach. A defining feature of the Science Teachers Learning from Lesson Analysis (STeLLA) Professional Development program is its use of videos of classroom instruction and examples of student work to promote teacher learning. Skilled facilitators guide teachers' analysis and discussion of other teachers' work; then, teachers begin to apply the analytical techniques they have learned to their own teaching. Adapting the STeLLA program to an online learning model is important because it can reach a broader and more diverse audience such as teachers working in rural school districts and underserved communities. To further promote the reach of STeLLA, the online version of STeLLA will engage and prepare teacher leaders to support their peers' engagement and understanding.

Guided by theories of situated cognition and cognitive apprenticeship this project focuses on two questions: How can the STeLLA professional development model be adapted to an online environment? and Does participation in the online model show meaningful teacher and student outcomes related to science teaching and learning? Challenges related to adaptation include understanding the duration and intensity of teacher engagement, the quality of their science content learning experiences, and how teacher learning is scaffolded across the online and traditional model. The project will unfold in two phases. Phase 1 uses a design-based research approach to rapidly enact, test, and revise online program components while remaining true to the design principles underlying the traditional STeLLA PD program. Phase 2 uses a quasi-experimental approach to test STeLLA Online's influence on teacher content knowledge, pedagogical content knowledge, practice and on upper elementary student science achievement. Comparisons will be made between STeLLA Online, face-to-face STeLLA, and a traditional professional development program that emphasizes deepening content knowledge only. This comparison leverages data from a previously-completed cluster randomized trial of STeLLA funded by the NSF.

Supporting Teachers in Responsive Instruction for Developing Expertise in Science (Collaborative Research: Linn)

This project takes advantage of advanced technologies to support science teachers to rapidly respond to diverse student ideas in their classrooms. Students will use web-based curriculum units to engage with models, simulations, and virtual experiments to write multiple explanations for standards-based science topics. The project will also design planning tools for teachers that will make suggestions relevant research-proven instructional strategies based on the real-time analysis of student responses.

Many teachers want to adapt their instruction to meet student learning needs, yet lack the time to regularly assess and analyze students' developing understandings. The Supporting Teachers in Responsive Instruction for Developing Expertise in Science (STRIDES) project takes advantage of advanced technologies to support science teachers to rapidly respond to diverse student ideas in their classrooms. In this project students will use web-based curriculum units to engage with models, simulations, and virtual experiments to write multiple explanations for standards-based science topics. Advanced technologies (including natural language processing) will be used to assess students' written responses and summaries their science understanding in real-time. The project will also design planning tools for teachers that will make suggestions relevant research-proven instructional strategies based on the real-time analysis of student responses. Research will examine how teachers make use of the feedback and suggestions to customize their instruction. Further we will study how these instructional changes help students develop coherent understanding of complex science topics and ability to make sense of models and graphs. The findings will be used to refine the tools that analyze the student essays and generate the summaries; improve the research-based instructional suggestions in the planning tool; and strengthen the online interface for teachers. The tools will be incorporated into open-source, freely available online curriculum units. STRIDES will directly benefit up to 30 teachers and 24,000 students from diverse school settings over four years.

Leveraging advances in natural language processing methods, the project will analyze student written explanations to provide fine-grained summaries to teachers about strengths and weaknesses in student work. Based on the linguistic analysis and logs of student navigation, the project will then provide instructional customizations based on learning science research, and study how teachers use them to improve student progress. Researchers will annually conduct at least 10 design or comparison studies, each involving up to 6 teachers and 300-600 students per year. Insights from this research will be captured in automated scoring algorithms, empirically tested and refined customization activities, and data logging techniques that can be used by other research and curriculum design programs to enable teacher customization.

GeoHazard: Modeling Natural Hazards and Assessing Risks

This project will develop and test a new instructional approach that integrates a data analysis tool with Earth systems models in a suite of online curriculum modules for middle and high school Earth science students. The modules will facilitate development of rich conceptual understandings related to the system science of natural hazards and their impacts.

Full Description: 

As human populations grow and spread into areas where extreme natural events impact lives, there is increasing need for innovative Earth science curriculum materials that help students interpret data and and understand the factors and risks associated with natural hazards. Studying the processes underlying these naturally occurring events and the relationships between humans and their environments would enrich the standard Earth science curriculum by providing students with valuable insights about the potential impacts of extreme natural events. This project will respond to that need by developing and testing a new instructional approach that integrates a data analysis tool with Earth systems models in a suite of online curriculum modules for middle and high school Earth science students. Each module will be designed as a sequence of activities lasting approximately 7-10 class periods. These will be stand-alone modules so each teacher can implement just one module or several modules. The modules will facilitate development of rich conceptual understandings related to the system science of natural hazards and their impacts. Students will develop scientific arguments that include risk assessment based on their understanding of real-world data and the particular Earth system being studied. The project will develop a set of computational models designed specifically to explore geoscience systems responsible for natural hazards. An open-source data analysis tool will also be modified for students to create and analyze visualizations of the magnitude, frequency, and distribution of real-world hazards and the impact of those hazards on people. Students will compare data generated from the Earth systems models with real-world data in order to develop an understanding of the cause and progression of natural hazards, as well as to make predictions and evaluate future risks.

The four-year, early stage design and development project will be conducted in two phases. In Phase 1, design-based research will be used to iteratively design and test Earth systems models. A team of five lead teachers will field test modules and provide focus group feedback during the development phase of the curricula. These lead teachers will provide input into the design and development of the tools, the organization and structure of the curriculum, and provide suggestions about classroom implementation to support the development of teacher support materials. After the models are developed, four curriculum modules related to hurricanes, earthquakes, floods, and wildfires will be developed, tested, and revised. In Phase 2, a group of 30 teachers will participate in implementation studies that will test usability of the modules across students from diverse backgrounds and feasibility of implementation across a range of classroom settings. Research will focus on understanding how to support student analysis of real-world datasets in order to improve their conceptual understanding of complex Earth systems associated with natural hazards. The project will also examine the role of uncertainty when students make scientific arguments that include predictions about the behaviors of complex systems and the uncertainties related to risk assessment. The project aims to clarify student views of uncertainty and how teachers can better support student understanding of the inherently uncertain nature of systems, models, and natural hazards, while understanding that models can be used to reduce impact. Questions guiding project research include: (1) How do students use flexible data visualizations to make sense of data and build and refine conceptual models about natural hazards? (2) How do students incorporate data from models and the real world in formulating scientific arguments; how do students use scientific uncertainty to assess risks based on their understanding of a natural hazard system; and how do students quantify and explain risks to humans and compare different sources of risks? And (3) Do GeoHazard curriculum modules help students make gains in risk-infused scientific argumentation practice and conceptual understanding underlying natural hazards? To what extent, for whom, and under what conditions is the GeoHazard curriculum useful in developing risk-infused scientific argumentation practice and conceptual understanding?
