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: 

This project will contribute to this mission by designing, developing, and examining the learning outcomes of a new curriculum unit for biology that embodies the conceptual framework of the Next Generation Science Standards (NGSS). The curriculum materials to be developed by this project will focus on two areas of study that are central to the life sciences: genetics and the processes of evolution by natural selection. These traditionally separate topics will be interlinked and will be designed to engage students in the disciplinary core ideas, crosscutting concepts, and the science and engineering practices defined by the NGSS. Once developed, the curriculum materials will be available online for use in high school biology courses nationwide.

This project will be guided by two main research questions: 1) How does learning progress when students experience a set of coherent biology learning materials that employ the principles of three-dimensional learning?; and 2) How do students' abilities to transfer understanding about the relationships between molecules, cells, organisms, and evolution change over time and from one biological phenomenon to another? The project will follow an iterative development plan involving cycles of designing, developing, testing and refining elements of the new curricular model. The project team will work with master teachers to design learning sequences that use six case studies to provide examples of how genetic and evolutionary processes are interlinked. An online data exploration environment will extend learning by enabling students to simulate phenomena being studied and explore data from multiple experimental trials as they seek patterns and construct cause-and-effect explanations of phenomena. Student learning will be measured using a variety of assessment tools, including multiple-choice assessment of student understanding, surveys, classroom observations and interviews, and embedded assessments and log files from the online learning environment.

Full Description: 

There is widespread recognition in educational literatures that academic discourse is important for supporting students' developing understanding in the disciplines of science and mathematics. College and career-ready standards also call for attention to supporting students' learning of how to think and communicate like disciplinary experts. The teaching practice of orchestrating classroom discussion is intended to support students in obtaining higher levels of academic achievement but also to support students' participation in a democratic society. However, research has found that teachers--particularly novice teachers--struggle to orchestrate discussion effectively for science and mathematics. The investigators of this project hypothesize that opportunities to 1) practice orchestrating discussions in simulated classroom environments; 2) receive constructive feedback on their practice; and 3) reflect on that feedback and their experiences with peers and teacher educators, develops preservice teachers' abilities to lead productive classroom discussion. This may allow them to be more effective at orchestrating discussion when they begin teaching real students in science and mathematics classrooms. The project team, which includes investigators from Educational Testing Service (ETS) and software engineers at Mursion, will develop, pilot, and validate eight discussion-oriented performance tasks that will be embedded in an online simulated classroom environment. The resulting research and development products could be used nationwide in teacher preparation and professional development settings to assess and develop teachers' ability to support classroom discussion in science and mathematics.

The Discovery Research K-12 (DRK-12) program 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. This Early Stage Design and Development project will 1) iteratively develop, pilot, and refine eight science and mathematics discussion-oriented performance tasks (six formative, two summative), scoring rubrics, and rater training materials; 2) deploy the intervention in four university sites, collecting data from 240 prospective teachers in both treatment and business-as-usual courses; and 3) use data analyses and expert review to build a five-part argument for the validity of the assessment and scoring rubrics. Data sources include prospective teachers' background and demographic information, cognitive interviews, surveys, scores on content knowledge for teaching (CKT) instruments, performance and scores on the developed performance tasks, discussion scores on Danielson's Framework for Teaching observation protocol, and case study interviews with prospective teachers. The project team will also conduct interviews with teacher educators and observe classroom debrief sessions with prospective teachers and their teacher educators. The research will examine each teacher's scores on two summative performance tasks administered pre- and post-intervention and will look for evidence of growth across three formative tasks. Linear regression models will be used to understand relationships among teachers' CKT scores, pre-intervention performance task scores, group assignment, and post-intervention performance task scores. A grounded theory approach to coding qualitative data of 24 case study teachers, observations of debrief sessions, and interviews with teacher educators will generate descriptive use cases, illustrating how the tools can support prospective teachers in learning how to facilitate discussions focused on science and mathematics argumentation. Mursion will develop a webpage on its website dedicated to this project that will allow the team to post the new performance-based tasks, scoring rubrics, and examples of performance in the simulated environment for teacher educators, educational researchers, and policy makers and collect feedback from them that can be used as another information source for refining tools and their use. Research findings will also be disseminated by more traditional means, such as papers in peer-reviewed research and practitioner journals and conference presentations.

This project at Jackson State University will investigate the effectiveness of a teacher academy resident model to recruit, license, induct, employ, and retain middle school and secondary science and mathematics teachers for high-need schools in the South. It will prepare new, highly-qualified science and mathematics teachers from historically Black universities in high-needs urban and rural schools. The project involves a partnership among three historically Black universities (Jackson, State University, Xavier University of Louisiana, and the University of Arkansas at Pine Bluff), and diverse urban and rural school districts in Jackson, Mississippi; New Orleans, Louisiana; and Pine Bluff Arkansas region that serve more than 175,000 students.

Participants will include 150 middle and secondary school teacher residents who will gain clinical mentored experience and develop familiarity with local schools. The 150 teacher residents supported by the program to National Board certification will obtain: state licensure/certification in science teaching, a master's degree, and initiation. The goal is to increase teacher retention and diversity rates. The research question guiding this focus is: Will training STEM graduates have a significant effect on the quality of K-12 instruction, teacher efficacy and satisfaction, STEM teacher retention, and students? Science and mathematics achievement? A quasi-experimental design will be used to evaluate project's effectiveness.

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

Award Number:

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.

An Intelligent Ecosystem for Science Writing Instruction

The ability to express scientific ideas in both written and oral form is an important 21st century skill. This project would help teachers help students achieve these skills through automating an effective feedback process, in ways that are customized to particular disciplines and local classroom needs, particularly in high needs districts. The project will contribute to knowledge about how students learn to write and how computer assisted systems can support this learning.

The ability to express scientific ideas in both written and oral form is an important 21st century skill. Teachers, employers, and college faculty lament the inability of many high school graduates to write clearly. This deficit in writing is due in part because teachers do not have the time to provide appropriate, timely feedback to students on their writing. This project would help teachers help students achieve these skills through automating an effective feedback process, in ways that are customized to particular disciplines and local classroom needs, particularly in high needs districts. The project will contribute to knowledge about how students learn to write and how computer assisted systems can support this learning.

This project will develop and test three tools: 1) Teaching resources organized as developmental trajectories for teachers to use (e.g. from more simple to more complex; with diagnostics and strategies for addressing particular challenges); 2) A teacher dashboard that uses Artificial Intelligence tools to provide timely formative assessment to teachers by highlighting problem areas in their students' writing and peer reviews; and 3) An online teacher resource exchange to rapidly grow the set of appropriate assignments that can be used with this approach, critically filtered by student performance metrics. The project builds on a current system called SWoRD, which supports student peer reviewing in many disciplines within and beyond science. Working with six lead teachers and larger set of pilot teachers, the project will develop a trajectory of effective writing assignments in Biology, Chemistry, and Physics. In year three, there will be a summative evaluation with 90 teachers.

Guiding Understanding via Information from Digital Environments (GUIDE)

Full Description: 

This project will develop and test a digital monitoring tool that will enable teachers to track student learning within a digital learning system and quickly adjust classroom instructional strategies to facilitate learning. The tool will be developed for use with an existing digital curriculum for high school genetics, and it will be tested in both introductory biology courses and advanced courses. The tool will be designed to analyze student progress within the digital curriculum and provide feedback to both students and teachers about challenges to learning as they are occurring. The system will simultaneously monitor and analyze the learning patterns of all students in a class, providing targeted feedback to individual students as needed, or enabling the teacher to make informed decisions about when some students need individual attention, or groups of students need help with a particular concept or learning challenge. As more digital learning experiences are incorporated into classroom practices, digital guidance systems such as this will be needed to help students and teachers effectively blend a variety of classroom learning experiences.

This design and development study focuses on improving student learning of domain-specific content and practices within traditional, technology-enriched classroom environments. The project will be guided by findings from prior research in two areas: the learning outcomes of game-like, simulation-based digital learning environments, and the effectiveness of intelligent tutoring systems. The system being developed in this project will construct analytic models of student knowledge and behavior from clickstream data and provide contextualized information at optimal junctures to students or teachers. This approach will enable a three-layered response system: a) direct, targeted support to individual students struggling with basic content; b) referral of a student to another student or group of students having encountered similar learning challenges; and c) feedback to teachers that would facilitate strategic guidance of student learning. Research questions guiding this project will focus on what information about student learning is most useful for guiding learning in digital environments, how can this information improve support for student learning within classrooms, and how does the availability and use of this information improve student knowledge and practices? The design and development work will be conducted over 4 years and will involve teachers and students in 22 classrooms in New England and North Carolina.

 

PlantingScience: Digging Deeper Together - A Model for Collaborative Teacher/Scientist Professional Development

This project will design, develop, and test a new professional development (PD) model for high school biology teachers that focuses on plant biology, an area of biology that teachers feel less prepared to teach. The new PD model will bring teachers and scientists together, in-person and online, to guide students in conducting authentic science investigations and to reflect on instructional practices and student learning.

This project will design, develop, and test a new professional development (PD) model for high school biology teachers that focuses on plant biology, an area of biology that teachers feel less prepared to teach. The new PD model will bring teachers and scientists together, in-person and online, to guide students in conducting authentic science investigations and to reflect on instructional practices and student learning. The project will also develop and test the outcomes of a summer institute for teachers and a website that will support the online mentoring of students and the professional development of teachers. Outcomes of the project will include the development of a facilitation guide for the teacher professional development model, a website to support student mentoring and teacher professional development, a series of resources for teachers and scientists to use in working with students, and empirical evidence of the success of the new professional development model.

This full research and development project will employ a pre-test/post-test control group design to test the efficacy of a professional development model for high school biology teachers. The professional development model is grounded in a theory of action based on the premise that when teachers are engaged with scientists and students in a technology-enabled learning community, students will demonstrate higher levels of achievement than those using more traditional instructional materials and methodologies. The means of post-intervention outcome measures will be compared across treatment and comparison groups in a cluster-randomized trial where teachers will be randomly assigned to treatment groups. The study will recruit a nation-wide sample to ensure that participants represent a wide array of geographic and demographic contexts, with preference given to Title 1 schools. The research questions are: a) To what extent does participation in the Digging Deeper community of teachers and scientists affect teacher knowledge and practices? b) To what extent does participation in the Digging Deeper community of teachers and scientists affect scientists? quality of mentorship and teaching? And c) To what extent does student use of the online program and participation in the learning community with scientist mentors affect student learning? Instruments will be developed or adapted to measure relevant student and teacher knowledge, student motivation, and teacher practices. Computer-mediated discourse analysis will be used over the course of the study to track online interactions among students, teachers, and science mentors.
