Full Description: 

This project will develop curricula for environmental/geoscience disciplines for high-school classrooms. It will teach a systems approach to problem solving through hands-on activities based on local data and issues. This will provide an opportunity for students to act in their communities while engaging in solving problems they find interesting, and require synthesis of prior learning. The Model My Watershed (MMW) v2 app will bring new environmental datasets and geospatial capabilities into the classroom, to provide a cloud-based learning and analysis platform accessible from a web browser on any computer or mobile device, thus overcoming the cost and technical obstacles to integrating Geographic Information System technology in secondary education. It will also integrate new low-cost environmental sensors that allow students to collect and upload their own data and compare them to data visualized on the new MMW v2. This project will transform the ability of teachers throughout the nation to introduce hands-on geospatial analysis activities in the classroom, to explore a wide range of geographic, social, political and environmental concepts and problems beyond the project's specific curricular focus.

The Next Generation Science Standards state that authentic research experiences are necessary to enhance STEM learning. A combination of computational modeling and data collection and analysis will be integrated into this project to address this need. Placing STEM content within a place- and problem-based framework enhances STEM learning. Students, working in groups, will not only design solutions, they will be required to defend them within the application portal through the creation of multimedia products such as videos, articles and web 2.0 presentations. The research plan tests the overall hypothesis that students are much more likely to develop an interest in careers that require systems thinking and/or spatial thinking, such as environmental sciences, if they are provided with problem-based, place-based, hands-on learning experiences using real data, authentic geospatial analysis tools and models, and opportunities to collect their own supporting data. The MMW v2 web app will include a data visualization tool that streams data related to the modeling application. This database will be modified to integrate student data so teachers and students can easily compare their data to data collected by other students and the government and research data. All data will be easily downloadable so that students can increase the use of real data to support the educational exercises. As a complement to the model-based activities, the project partners will design, manufacture, and distribute a low-cost environmental monitoring device, called the Watershed Tracker. This device will allow students to collect real-world data to enhance their understanding of watershed dynamics. Featuring temperature, light, humidity, and soil moisture sensors, the Watershed Tracker will be designed to connect to tablets and smartphones through the audio jack common to all of these devices.

Full Description: 

For the past 25 years, three major goals have animated U.S. educational policy: developing more knowledgeable teachers, implementing more challenging curricula, and fostering more ambitious instruction in classrooms. Yet despite volumes of policy guidance, on-the-ground effort, and research over the past decades, few comprehensive and representative portraits of teacher and teaching quality in U.S. classrooms exist. Instead, most research into these topics has been conducted with small or nonrepresentative samples, with the result that it is difficult to ascertain what, if any, progress has been made toward the three goals. Unlike student achievement, which the National Assessment of Educational Progress has tracked for almost 50 years, the classroom experiences of the typical U.S. student remain obscure.

To address this issue, the 4-year descriptive study will begin by systematically tracking key instructional indicators in middle school mathematics classrooms, specifically, teachers' mathematical knowledge, the curriculum in place, and the nature of mathematics instruction offered to students. To initiate this line of research, the research team will collect data in 2015 from a national representative sample of 600 U.S. middle school mathematics teachers. A written survey will build on one conducted in 2005-06, allowing for the comparison over time of teachers' curriculum use and mathematical knowledge. The research team will also record and score videos of instruction from a subset of these teachers, enabling both a description of current instruction and a comparison to lessons captured during the 1999 TIMSS video study. Both the survey and video datasets can serve as referents for future studies of instruction, for instance, studies investigating whether student participation in the development of mathematical ideas has changed over time. The research team will use both old and new technologies to complete the study. The mail survey will consist of existing items that tap teachers' mathematical knowledge for teaching, or the professional knowledge teachers draw upon in providing mathematics instruction to children. To conduct the video study, they will mail tablets for teachers to record their own instruction, and guidance on taping will be provided via YouTube video. The lessons that result will be scored using the Mathematical Quality of Instruction (MQI) instrument. The MQI measures key dimensions of mathematics classrooms, including the proportion of class time spent on mathematical tasks, the mathematical integrity of lesson content, and the nature of student participation in the development of mathematical ideas. Video and data from the survey will be made available to other researchers for scoring with other methods and observation instruments. Teachers, parents and students will be asked to consent to their classroom videos being made available. The study is largely descriptive, as are many others of its kind. However, describing the range of U.S. instruction can have a profound effect on the field, much as the TIMSS video studies did over a decade ago. Establishing methodologies for studying teachers and teaching at scale will contribute to efforts to evaluate and monitor progress toward broad-reaching national goals.

Full Description: 

The 4-year project, Supports for Science and Mathematics Learning in Pre-Kindergarten Dual Language Learners: Designing and Expanding a Professional Development System (SciMath-DLL), will address a number of educational challenges. Global society requires citizens and a workforce that are literate in science, technology, engineering, and mathematics (STEM), but many U.S. students remain ill prepared in these areas. At the same time, the children who fill U.S. classrooms increasingly speak a non-English home language, with the highest concentration in the early grades. Many young children are also at risk for lack of school readiness in language, literacy, mathematics, and science due to family background factors. Educational efforts to offset early risk factors can be successful, with clear links between high quality early learning experiences and later academic outcomes. SciMath-DLL will help teachers provide effective mathematics and science learning experiences for their students. Early educational support is critical to assure that all students, regardless of socioeconomic or linguistic background, learn the STEM content required to become science and mathematics literate. Converging lines of research suggest that participation in sustained mathematics and science learning activities could enhance the school readiness of preschool dual language learners. Positive effects of combining science inquiry with supports for English-language learning have been identified for older students. For preschoolers, sustained science and math learning opportunities enhance language and pre-literacy skills for children learning one language. Mathematics skills and science knowledge also predict later mathematics, science, and reading achievement. What has not been studied is the extent to which rich science and mathematics experiences in preschool lead to better mathematics and science readiness and improved language skills for preschool DLLs. Because the preschool teaching force is not prepared to support STEM learning or to provide effective supports for DLLs, professional development to improve knowledge and practice in these areas is required before children's learning outcomes can be improved.

SciMath-DLL is an innovative preschool professional development (PD) model that integrates supports for DLLs with high quality science and mathematics instructional offerings. It engages teachers with workshops, classroom-based coaching, and professional learning communities. Development and research activities incorporate cycles of design-expert review-enactment- analysis-redesign; collaboration between researcher-educator teams at all project stages; use of multiple kinds of data and data sources to establish claims; and more traditional, experimental methodologies. Based on initial evidence of promise, the SciMath-DLL project will expand PD offerings to include web-based materials, making the PD more flexible for use in a range of educational settings and training circumstances. An efficacy study will be completed to examine the potential of the SciMath-DLL resources, model, and tools to generate positive effects on teacher attitudes, knowledge, and practice for early mathematics and science and on children's readiness in these domains in settings that serve children learning two languages. By creating a suite of tools that can be used under differing educational circumstances to improve professional knowledge, skill, and practice around STEM, the project increases the number of teachers who are prepared to support children as STEM learners and, thus, the number of children who can be supported as STEM learners.

Science in the Learning Gardens (SciLG): Factors that Support Racial and Ethnic Minority Students’ Success in Low-Income Middle Schools

Science in the Learning Gardens (SciLG) designs and implements curriculum aligned with Next Generation Science Standards (NGSS) and uses school gardens as learning contexts in grade 6 (2014-2015), grade 7 (2015-2016) and grade 8 (2016-2017) in two low-income urban schools. The project investigates the extent to which SciLG activities predict students’ STEM identity, motivation, learning, and grades in science using a theoretical model of motivational development.

Full Description: 

Science in the Learning Gardens (SciLG) will use school gardens as the context for learning at two low-income middle schools with predominantly racial and ethnic minority students in Portland, Oregon. There are thousands of gardens flourishing across the country that are underutilized as contexts for active engagement in the middle grades. School gardens provide important cultural contexts while addressing environmental and food issues. SciLG will bring underrepresented youth into gardens at a critical time in their intellectual development to broaden the factors that support motivation to pursue STEM careers and educational pathways. The project will adapt, organize, and align two disparate sets of existing resources into the project curriculum: 6th grade science curriculum resources, and garden-based lessons and units. The curriculum will be directly aligned with the Next Generation Science Standards (NGSS). 

The project will use a design-based research approach to refine instruction and formative assessment, and to investigate factors for student success in science proficiency and their motivational engagement in relation to the garden curriculum. The curriculum will be pilot-tested during the first year of the project in five sixth-grade classes with 240 students in Portland Public Schools. Students will be followed longitudinally in grades 7 and 8 in years 2 and 3 respectively, as curricular integration continues. The research team will support participating teachers each year in using their schools' gardens, and study how this context can serve as an effective pedagogical strategy for NGSS-aligned science curriculum. Academic learning will be measured by assessments of student progress towards the end of middle-school goals defined by NGSS. Motivation will be measured by a validated motivational engagement instrument. SciLG results along with the motivational engagement instrument will be disseminated widely through a variety of professional networks to stimulate implementation nationwide.

Promoting Active Learning Strategies in Biology (PALS)

This project examines the potential of two research-based and college-tested active learning strategies in high school classrooms: Process Oriented Guided Inquiry Learning (POGIL) and Peer Instruction by adapting the strategies for implementation in biology classes, with the goal of determining which strategy shows the most promise for increasing student achievement and attitudes toward science.

Full Description: 

The use of active learning strategies has long been advocated in the sciences, but high school science instruction remains highly didactic across the country. This project addresses this longstanding concern by examining the potential of two research-based and college-tested learning strategies in high school classrooms: Process Oriented Guided Inquiry Learning (POGIL) and Peer Instruction. The POGIL strategy was developed initially for chemistry classes, and Peer Instruction was developed within physics classes. These two learning strategies will be adapted for implementation in biology classes, with the goal of determining which strategy shows the most promise for increasing student achievement and attitudes toward science. The project will also study the influence of these instructional strategies on teacher beliefs about active learning and the contributions of these beliefs on student success in biology. Creation of the professional development model and materials for this project bring together high school biology teachers, university biology faculty, and science education specialists.

The project will conduct design and development research to iteratively develop the instructional materials through a collaboration of high school teachers and college faculty members experienced in using the instructional approaches being compared. Adaptation of the learning strategies for use in biology was chosen because biology is the science course most often taught across schools in the country, and it is required for graduation in the state where this project is being conducted. To compare the outcomes of the two instructional approaches, 42 teacher pairs will be randomly assigned to one of three treatment groups: POGIL, Peer Instruction, or traditional instruction. Outcomes of the instructional approaches will be measured in terms of conceptual gains among teachers and students, attitudes toward science, personal agency beliefs, and instructional implementation fidelity.

Investigating How to Enhance Scientific Argumentation through Automated Feedback in the Context of Two High School Earth Science Curriculum Units

This project responds to the need for technology-enhanced assessments that promote the critical practice of scientific argumentation--making and explaining a claim from evidence about a scientific question and critically evaluating sources of uncertainty in the claim. It will investigate how to enhance this practice through automated scoring and immediate feedback in the context of two high school curriculum units--climate change and fresh-water availability--in schools with diverse student populations.

Full Description: 

With the current emphasis on learning science by actively engaging in the practices of science, and the call for integration of instruction and assessment; new resources, models, and technologies are being developed to improve K-12 science learning. Student assessment has become a nationwide educational priority due, in part, to the need for relevant and timely data that inform teachers, administrators, researchers, and the public about how all students perform and think while learning science. This project responds to the need for technology-enhanced assessments that promote the critical practice of scientific argumentation--making and explaining a claim from evidence about a scientific question and critically evaluating sources of uncertainty in the claim. It will investigate how to enhance this practice through automated scoring and immediate feedback in the context of two high school curriculum units--climate change and fresh-water availability--in schools with diverse student populations. The project will apply advanced automated scoring tools to students' written scientific arguments, provide individual students with customized feedback, and teachers with class-level information to assist them with improving scientific argumentation. The key outcome of this effort will be a technology-supported assessment model of how to advance the understanding of argumentation, and the use of multi-level feedback as a component of effective teaching and learning. The project will strengthen the program's current set of funded activities on assessment, focusing these efforts on students' argumentation as a complex science practice.

This design and development research targets high school students (n=1,940) and teachers (n=22) in up to 10 states over four years. The research questions are: (1) To what extent can automated scoring tools, such as c-rater and c-rater-ML, diagnose students' explanations and uncertainty articulations as compared to human diagnosis?; (2) How should feedback be designed and delivered to help students improve scientific argumentation?; (3) How do teachers use and interact with class-level automated scores and feedback to support students' scientific argumentation with real-data and models?; and (4) How do students perceive their overall experience with the automated scores and immediate feedback when learning core ideas in climate change and fresh-water availability topics through scientific argumentation enhanced with modeling? In Years 1 and 2, plans are to conduct feasibility studies to build automated scoring models and design feedback for previously tested assessments for the two curriculum units. In Year 3, the project will implement design studies in order to identify effective feedback through random assignment. In Year 4, a pilot study will investigate if effective feedback should be offered with or without scores. The project will employ a mixed-methods approach. Data-gathering strategies will include classroom observations; screencast and log data of teachers' and students' interaction with automated feedback; teachers' and students' surveys with selected- and open-ended questions; and in-depth interviews with teachers and students. All constructed-response explanations and uncertainty items will be scored using automated scoring engines with fine-grained rubrics. Data analysis strategies will include multiple criteria to evaluate the quality of automated scores; descriptive statistical abalyses; analysis of variance to investigate differences in outcomes from the designed studies' pre/posttests and embedded assessments; analysis of covariance to investigate student learning trajectories; two-level hierarchical linear modeling to study the clustering of students within a class; and analysis of screencasts and log data.

Instructional Leadership for Scientific Practices: Resources for Principals in Evaluating and Supporting Teachers' Science Instruction

This project will research the knowledge and supervision skills principals' and other instructional leaders' need to support teachers in successfully integrating scientific practices into their instruction, and develop innovative resources to support these leaders with a particular focus on high-minority, urban schools. The project will contribute to the emerging but limited literature on instructional leadership in science at the K-8 school level.

Full Description: 

Although K-8 principals are responsible for instructional improvement across all subject areas, their focus has traditionally been on literacy and mathematics and only occasionally on science content and practice. New standards and assessments in science require that principals and other instructional leaders provide significant support to teachers to help them successfully integrate scientific practices into their instruction. There is evidence that these instructional leaders often lack the knowledge, resources or skills to provide this support. This project will research the knowledge and supervision skills principals' and other instructional leaders' need to support teachers in successfully integrating scientific practices into their instruction, and develop innovative resources to support these leaders with a particular focus on high-minority, urban schools. The project will contribute to the emerging but limited literature on instructional leadership in science at the K-8 school level.

The resources developed will involve: (1) Introducing scientific practices (including rationales, descriptions and vignettes illustrating each of the 8 scientific practices); (2) Using tools in schools (providing an observation protocol, teacher feedback form and improvement planning template); and (3) Analyzing sample video (including links to video of K-8 science instruction, completed supervision tools, explanations of their coding, and discussion of how to use them with teachers). The project will conduct in-depth interviews with four principals, work with 25 principals in the Boston Public Schools to iteratively design and test the resources. The project will also develop a measure of Leadership Content Knowledge of Scientific Practices (LCK-SP) which will be used to assess principals' knowledge. The project's research component will: (1) investigate principals' current knowledge about scientific practices and methods for supervision of science instruction; and (2) examine how resources can be designed to support instructional leaders' content knowledge of scientific practices.

Identifying an Effective and Scalable Model of Lesson Study

This project investigates the variation in teachers' practice of lesson study to identify effective and scalable design features of lesson study associated with student mathematics achievement growth in Florida. Lesson study is a teacher professional development model in which a group of teachers works collaboratively to plan a lesson, observe the lesson in a classroom with students, and analyze and discuss the student work and understanding in response to the lesson.

This project investigates the variation in teachers' practice of lesson study to identify effective and scalable design features of lesson study associated with student mathematics achievement growth in Florida. Lesson study is a teacher professional development model in which a group of teachers works collaboratively to plan a lesson, observe the lesson in a classroom with students, and analyze and discuss the student work and understanding in response to the lesson. Florida is the first state to promote lesson study as a statewide professional development model for implementing the Common Core State Standards for Mathematics and improving instruction and student achievement. The original lesson study model imported from Japan poses a challenge for implementation and scalability in the United States, and there is emerging evidence that modifications have been made to make it feasible within the constraints of teachers' work schedules and school structures. Thus, there is an urgent need to investigate the variation in lesson study practice and how modified design features of mathematics lesson study are associated with improvement of student mathematics achievement. The research team will conduct a statewide survey of approximately 1,000 teachers in grades 3-8 who are practicing mathematics lesson study during the 2015-2016 academic year. They will examine variations in four design features of lesson study (structure, facilitator, knowledge resources for lesson planning, and research lesson and discussion) and their associated organizational supports. They will examine the relationships between these design features and the original lesson study model, teacher learning, and students' mathematics achievement growth.

This project is designed to advance the scholarship and practice of lesson study by: (1) identifying an effective and scalable model of mathematics lesson study with specific design features that are associated with positive teacher learning experience and improved student mathematics achievement; (2) advancing practical knowledge on how this effective and scalable model of mathematics lesson study can be practiced, based on in-depth case studies of lesson study groups; and (3) contributing to teacher learning principles that can be applied to various professional development programs in mathematics. The project will disseminate evidence regarding the characteristics of an effective and scalable mathematics lesson study model to state and district-level facilitators across the country. The project will also develop a Florida Lesson Study Network (FLSN) to share resources and facilitate communications regarding lesson study practice.

From Elementary Generalist to Mathematics Specialist: Examining Teacher Practice and Student Outcomes in Departmental and Self-Contained Models

This research investigates student mathematics learning outcomes at the elementary level in relation to teacher expertise (elementary teachers with math specialist certification versus generally prepared elementary teachers) and school organization (departmentalized versus self-contained mathematics classrooms). Findings will provide evidence of the impact of content-specific teacher expertise and a departmentalized school organizational model that offers students access to well-qualified teachers of mathematics with no additional staffing costs.

Full Description: 

This research investigates student mathematics learning outcomes at the elementary level in relation to teacher expertise (elementary teachers with math specialist certification versus generally prepared elementary teachers) and school organization (departmentalized versus self-contained mathematics classrooms). University of Missouri researchers will organize and facilitate the research in multiple Missouri public and private school sites. Findings will provide evidence of the impact of content-specific teacher expertise and a departmentalized school organizational model that offers students access to well-qualified teachers of mathematics with no additional staffing costs. To investigate the impact of teacher expertise and school organization on student learning experimental, quasi-experimental, and qualitative designs are employed. Specifically, 80 teachers who have earned state certification as Elementary Mathematics Specialists (hereafter, "EMS teachers") will be selected to participate in the study. Employing a randomized experimental design, half of the EMS teachers will be assigned to teach in a departmental model (Condition 1) in their school, teaching two or more sections of grade 4 mathematics. The other half will remain in generalist (hereafter, self-contained) positions (Condition 2) in their school, teaching all regular subjects to a single class of students. A comparison group of 40 non-EMS teachers with self-contained teaching assignments (Condition 3) will be selected from the same schools in Condition 2. The Smarter Balanced assessment will provide a baseline measure of students' prior achievement in grade 3 and also a measure of the mathematics achievement of grade 4 students taught by the 120 teachers in the study. The project team will analyze student-level mathematics scores linked with specific teachers.

Improving student achievement in mathematics at the elementary level is particularly challenging due to the way elementary students are generally organized for instruction (e.g., one teacher responsible for teaching all subjects to 25-30 students). Because elementary teachers must be knowledgeable about many content areas, they rarely study mathematics in depth, even though there is a growing body of evidence showing the impact of specialized mathematical knowledge for teaching on student learning outcomes. This study carefully researches an alternative model, where elementary teachers with special training in mathematics teaching and learning are assigned more than one single class of students for mathematics instruction. Findings from the research will provide evidence about the impact of both certification as an elementary mathematics specialist and teaching in a departmental assignment on student learning. The results will help school and district leaders better plan for assignment of staff to provide all students with access to high quality mathematics instruction.

Focus on Energy: Preparing Elementary Teachers to Meet the NGSS Challenge (Collaborative Research: Vokos)

This project will develop and investigate the opportunities and limitations of Focus on Energy, a professional development (PD) system for elementary teachers (grades 3-5). The PD will contain: resources that will help teachers to interpret, evaluate and cultivate students' ideas about energy; classroom activities to help them to identify, track and represent energy forms and flows; and supports to help them in engaging students in these activities.

Full Description: 

The Next Generation Science Standards (NGSS) identify an ambitious progression for learning energy, beginning in elementary school. To help the nation's teachers address this challenge, this project will develop and investigate the opportunities and limitations of Focus on Energy, a professional development (PD) system for elementary teachers (grades 3-5). The PD will contain: resources that will help teachers to interpret, evaluate and cultivate students' ideas about energy; classroom activities to help them to identify, track and represent energy forms and flows; and supports to help them in engaging students in these activities. Teachers will receive the science and pedagogical content knowledge they need to teach about energy in a crosscutting way across all their science curricula; students will be intellectually engaged in the practice of developing, testing, and revising a model of energy they can use to describe phenomena both in school and in their everyday lives; and formative assessment will guide the moment-by-moment advancement of students' ideas about energy.

This project will develop and test a scalable model of PD that will enhance the ability of in-service early elementary teachers to help students learn energy concepts by coordinating formative assessment, face-to-face and web-based PD activities. Researchers will develop and iteratively refine tools to assess both teacher and student energy reasoning strategies. The goals of the project include (1) teachers' increased facility with, and disciplined application of, representations and energy reasoning to make sense of everyday phenomena in terms of energy; (2) teachers' increased ability to interpret student representations and ideas about energy to make instructional decisions; and (3) students' improved use of representations and energy reasoning to develop and refine models that describe energy forms and flows associated with everyday phenomena. The web-based product will contain: a set of formative assessments to help teachers to interpret student ideas about energy based on the Facets model; a series of classroom tested activities to introduce the Energy Tracking Lens (method to explore energy concept using multiple representations); and videos of classroom exemplars as well as scientists thinking out loud while using the Energy Tracking Lens. The project will refine the existing PD and build a system that supports online implementation by constructing a facilitator's guide so that the online community can run with one facilitator.
