Full Description: 

The project will create opportunities for teachers to develop programming content knowledge and new understandings of the creative possibilities in computer science education, thereby increasing opportunities for students to develop conceptual and creative fluency with programming. K-12 introductory programming experiences are often highly scaffolded, and it can be challenging for students to transition from constrained exercises to open-ended programming activities encountered later in-and out of-school. Teachers can provide critical support to help students solve problems and develop the cognitive, social, and emotional capacities required for conceptually and creatively complex programming challenges. Teachers - particularly elementary and middle school teachers, especially in rural and Title I schools - often lack the programming content knowledge, skills, and practices needed to support deeper and more meaningful programming experiences for students. Professional development opportunities can cultivate teacher expertise, especially when supported by curricular materials that bridge teachers' professional learning and students' classroom learning. This research responds to these needs, addressing key national priorities for increasing access to high-quality K-12 computer science education for all students through teacher professional development.

The project will involve the design and evaluation of (1) an online learning experience for teachers to develop conceptual and creative fluency through short, daily programming prompts (featuring the Scratch programming environment), and (2) educative curricular materials for the classroom (based on the online experience). The online experience and curricular materials will be developed in collaboration with three 4th through 6th-grade rural or Title I teachers. The project will evaluate teacher learning in the online experience using mixed-methods analyses of pre/post-survey data of teachers' perceived expertise and quantitative analyses of teachers' programs and evolving conceptual knowledge. Three additional 4th through 6th-grade teachers will pilot the curricular materials in their classrooms. The six pilot teachers will maintain field journals about their experiences and will participate in interviews, evaluating use of the resources in practice. An ethnography of one teacher's classroom will be developed to further contribute to understandings of the classroom-level resources in action, including students' experiences and learning. Student learning will be evaluated through student interviews and analyses of student projects. Project outcomes will inform how computer science conceptual knowledge and creative fluency can be developed both for teachers and their students' knowledge and fluency that will be critical for students' future success in work and life.

Full Description: 

The aim of this project is to enact and study a process in which middle school teachers of mathematics and visual arts co-design and teach activities that combine math and art to teach data science. Many existing efforts to promote data literacy are grounded in mathematical concepts of central tendency and variation, and typically are narrowly focused in single subject domains. Taking an art-based perspective on data science has the potential to promote student relevance, accessibility, engagement, reasoning, and meaning-making with data science. Moreover, visualization technology has advanced to a degree that the relation between the information in data and visual aesthetic can be leveraged easily. To explore the opportunity this offers, research on this project will examine how to equip teachers to develop such interdisciplinary pedagogical approaches to cultivate their students' data literacy. This exploratory project will provide support for 12 teachers during summer workshops and during the school year as these teachers implement their co-designed units in their classrooms. The work addresses the following questions: (1) How do we support effective co-design of data literacy units among art teachers, mathematics teachers, and researchers? (2) How are teachers able to use the unit materials in their classrooms to engage students in data literacy? And (3) How does an art-based approach support students' data literacy? Answers to these questions will build an understanding of how to support interdisciplinary curriculum design collaborations among researchers and teachers. They will also show how art-integrated, maker-oriented activities can support middle school learners' data literacy development; and how to design technologies that are accessible and powerful to teachers and learners in these interdisciplinary environments.

Through summer workshops and year-round design collaborations, the project will iteratively design, test and refine four units for middle school classrooms, including activities, tools, and assessments, to promote students' data literacy. Data will be collected from co-design sessions as well as classroom-enactments, and will include observations, video/audio recordings, student- and teacher-generated artifacts, and pre and post assessments of students' knowledge and self-efficacy. Mixed methods analyses of these data, and syntheses of findings across participants, classroom enactments, and project years, will explore effective ways to support co-design among art teachers, mathematics teachers, and researchers; and the impact of art-integrated activities on students' data literacy. This project will reach 12 teachers and their students across 6 New York city schools. By building capacity and knowledge about how to initiate and sustain teachers' interdisciplinary curriculum collaborations, the project will have broader impact. Refined project materials, including pedagogical approaches, toolkits and adaptable classroom activities, will be disseminated to facilitate classroom adoption by other educators who wish to undertake similar art-integrated data literacy curriculum design collaborations, and will thus ultimately broaden participation in data science among diverse youth within and beyond New York City.

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.

Developing Organizational Capacity to Improve K-8 Mathematics Teaching and Learning

This project will develop and test a leadership model to improve K-8 mathematics teaching and learning by involving stakeholders across the K-8 spectrum. The project will support teachers, teacher leaders, and administrators in collectively identifying and addressing problems of practice in the teaching and learning of mathematics, and in turn develop plans to improve school and district organizational capacities to support stronger mathematics teaching.

Full Description: 

The Developing Organizational Capacity to Improve K-8 Mathematics Teaching and Learning is a 4-year implementation and improvement project. The project will develop and test a leadership model to improve K-8 mathematics teaching and learning by involving stakeholders across the K-8 spectrum. The project will support teachers, teacher leaders, and administrators in collectively identifying and addressing problems of practice in the teaching and learning of mathematics, and in turn develop plans to improve school and district organizational capacities to support stronger mathematics teaching. At the heart of the project is the Elementary Mathematics Leadership (EML) model, which is designed to improve stakeholder understandings of effective math teaching practices. The EML model involves collaboratively identifying classroom-based problems of practice with school and district personnel, designing and implementing professional development aligned with the problems of practice, and iterating those cycles of development, implementation, and revision to assess the model's effectiveness.

The EML model operates at the teacher, school, and district level using a design-based implementation research approach. At the district level, leadership teams in conjunction with researchers will identify problems of practice for which work on those problems will lead to a more coherent mathematics instruction in the district. Following this, professional development and coaching at the teacher level will be designed and implemented to target the problem of practice, with a focus on big ideas within the Common Core State Standards for Mathematics. This phase of the model also includes professional development aimed at school leaders and district administrators to strengthen organizational capacity to support and lead change related to the problem of practice. The final phase of the model calls on researchers, district, and school personnel to engage in an annual redesign of the intervention, making use of data gathered during the school year and evidence about what is happening in classrooms. This design acknowledges the broader policy context in which schools and districts operate as they work towards instructional change. To evaluate the effectiveness of the overall EML model, the project will collect a wide variety of data, including student achievement outcomes using standardized tests; assessments of teachers' mathematical knowledge, instructional practices, and efficacy measures; and measures of leader, administrator, and organizational capacities to support high-quality mathematics instruction. Four districts will be recruited to participate, enacting the model in pairs with a staggered start for one pair of districts to be able to measure treatment effects, using a variation of a switching replications design. Classroom practice and teacher outcomes will be assessed using a variety of MKT assessments, the Mathematical Quality of Instruction (MQI), and the Instructional Quality Assessment (IQA). School level outcomes will be collected via a leadership assessment and interview data, and district level outcomes will be assessed through the use of interview and documentary data. Analysis will include a statistical analysis of the EML model using hierarchical linear modeling, MANOVA/ANOVA, and regression as appropriate at the level of students and teachers, and qualitative analysis and descriptive statistics will be used at the school and district level due to small sample size.

Building Professional Capital in Elementary Science Teaching through a District-wide Networked Improvement Community Model

This project will focus on a networked improvement community (NIC) model of professional learning that shifts K-5 science instruction from traditional approaches to a three-dimensional design as outlined in the Next Generation Science Standards. The project will feature a multi-level model involving university educators and researchers and school district practitioners in an effort to co-defined problems of practice valuable to both parties.

Full Description: 

This project will focus on a networked improvement community (NIC) model of professional learning that shifts K-5 science instruction from traditional approaches to a three-dimensional design as outlined in the Next Generation Science Standards. The need to make this shift stems from the school district's decision to address inequities in science as some schools offer minimal to no science instruction during the elementary years. The NIC model will draw on expertise from school personnel and university partners to ensure that students will have access to and benefit from authentic model-based inquiry daily in the early grades. This model embraces the challenges of scale and sustainability by targeting the design and substance of professional learning and its organization within the district, balancing integration with existing system infrastructure, and shifting the system based on theory-driven practices. To prepare teachers for this major change, professional development will shift from: (1) training on the use of kit-based curricular materials to professional learning grounded in NGSS-inspired sets of practices and tools; (2) working as individual practitioners to teaching as collaborative investigations; (3) using centralized efforts to distributed knowledge-building and leadership; (4) learning science as decontextualized facts to deep engagement with real-world phenomena; and (5) teaching lessons as prescribed by curriculum to a focus on responsive teaching and building on students' funds of knowledge. The NIC model will provide a pathway for integrating and implementing these shifts via a multilevel, knowledge-building, problem-solving system. This system will go beyond a single focus on improving students' understanding of science content to incorporating teaching practices that advances knowledge about student's written and spoken scientific language and use of explanations and arguments. Through the NIC model all K-5 elementary students in the district will benefit from a rigorous and equitable approach to science learning.

This project will feature a multi-level model involving university educators and researchers and school district practitioners in an effort to co-defined problems of practice valuable to both parties. A mixed methods research design will examine how the NIC model develops professional capital through changes in implementation over multiple iterations. These changes will be captured through short and long-term instruments. Regarding the shorter term, practical measures sensitive to change and directly tied to small manageable, short-term goals will provide quick responses to everyday real-time questions. These measures will help assess specific improvement goals using language relevant and meaningful to researchers and practitioners. For longer term goals, in-depth case studies, interviews, observations, pre-posttests, surveys, and questionnaires will collect data on several variables critical to documenting improvements at the teacher and student levels. Both sets of data will generate knowledge about ambitious and equitable science teaching practices with a focus on students' cultural and linguistic resources and experiences. Through such pathways, knowledge will be generated on teachers' and students' growth as active builders and collaborators in the development of improved learning and experiences. The outcomes will identify critical facets that support advances and sustainability that illuminate variations within the district to better understand what works, for whom, and under what conditions. the research findings will also be used to inform decision making about teaching science at the elementary grades and to further refine equity-based practices, resources, and tools for building on students' funds of knowledge vital to supporting, sustaining, and scaling educational outcomes for all students in the district and beyond.

Professional Development for Teaching and Learning about Energy and Equity in High School Physics (Collaborative Research: Scherr)

Full Description: 

This project will research and develop instructional materials and conduct professional development for teachers to help students understand energy flow, an important scientific concept with economic and social implications. This energy learning is the foundation for informed decision-making about sustainable and just use of energy resources. Energy issues are not only issues of science and technology, but must be integrated with civics, history, economics, sociology, psychology, and politics to understand and solve modern energy problems. Placing the scientific concept of energy in this social context presents an opportunity to advance science education as equitable and culturally responsive.

This project will create a model for secondary science teacher professional development that integrates science concepts with equity education. This model promotes a key epistemological issue: that science concepts are not culture-free or socially neutral ideas, but rather are concepts created and sustained by people in specific times and places for the purposes of (1) addressing specific social needs and (2) empowering people or groups of people. The two major components of the project are (1) the professional development experience, including both an intensive in-person summer workshop and an online professional learning community, and (2)an energy and equity portal, including an instructional materials library, an action research exchange, and a community forum for teacher discussions. The portal will provide technical resources to support the PLC, including support for sharing instructional materials and reporting on action research. The research plan includes exploratory, development and application phases. The researchers will identify teacher learning in the first iteration of PD, collect and analyze the instructional artifacts to inform how teacher engage with, participate in, and build an understanding energy as a historically and politically situated science concept. A team of scholar-videographers will observe, taking real-time field notes and making daily memos. The research team will use the instructional artifacts, video recordings, field notes, and memos as a basis for analysis through the next academic year. The result will be a nationally significant community of teacher-leaders and library of research-tested instructional materials that are responsive to students' scientific ideas, relevant to socio-political concerns about energy sustainability, respectful of students' cultures, and open to all students no matter their cultural background. Teachers participating in the project will learn to explain how scientific concepts of energy reflect culturally specific values, analyze socio-politically relevant energy scenarios, learn the historic and present-day inequities in the energy industry and in science participation, and be supported in preparing instruction for secondary students that is culturally responsive and relevant to their students' communities.

Full Description: 

This is a late-stage design and development proposal in the teaching strand which addresses the teaching and learning of chemistry at the secondary level, grades 10-12. There is a critical need to transform chemistry teaching and learning from an emphasis on description of phenomena to deep understanding consistent with the Next Generation Science Standards (NGSS). The project will establish a sustained community of practice of teachers skilled in the VisChem Approach and a group of new teaching and research scholars with expertise in building conceptual understanding through the effective use of visualization. The project will help students move from describing phenomena to explaining their causes from a molecular-level perspectives (e.g., carbon dioxide in climate change, DNA changes in genetically modified organisms). With a focus on traditionally under-served groups including English Language Learners, the project will impact up to 80,000 high school chemistry students from a broad range of socioeconomic, geographic, and racial backgrounds.

This project will develop teachers' knowledge and skills to help their students build accurate molecular-level mental models to explain phenomena as opposed to the overemphasis on description with abstract symbolism and language. Three chemistry teacher cohorts (N = 64) will participate in intensive nstitutes to learn the research foundation and pedagogical moves for the VisChem approach. The approach uses carefully produced dynamic visualizations with teaching strategies informed by a cognitive learning model. Key to VisChem is communication of internal visualizations using storyboards (drawings with explanation) of chemical and physical changes. The project will use an iterative research design examining teacher and student learning in the Institutes and how they implement the learning in classrooms. Data collected will include teachers' storyboards, classroom videos, and pre/post student assessments. Evaluation will provide iterative feedback to incrementally improve the institutes during the project.
