Full Description: 

This five-year project investigates how to provide continuous assessment and feedback to guide students' understanding during science inquiry-learning experiences, as well as detailed guidance to teachers and administrators through a technology-enhanced system. The assessment system integrates validated automated scorings for students' written responses to open-ended assessment items (i.e., short essays, science narratives, concept mapping, graphing problems, and virtual experiments) into the "Web-based Inquiry Science Environment" (WISE) program. WISE is an online science-inquiry curricula that supports deep understanding through visualization of processes not directly observable, virtual experiments, graphing results, collaboration, and response to prompts for explanations. In partnership with Educational Testing Services (ETS), project goals are: (1) to develop five automated inquiry assessment activities that capture students' abilities to integrate their ideas and form coherent scientific arguments; (2) to customize WISE by incorporating automated scores; (3) to investigate how students' systematic feedback based on these scores improve their learning outcomes; and (4) to design professional development resources to help teachers use scores to improve classroom instruction, and administrators to make better informed decisions about teacher professional development and inquiry instruction. The project targets general science (life, physical, and earth) in three northern California school districts, five middle schools serving over 4,000 6th-8th grade students with diverse cultural and linguistic backgrounds, and 29 science teachers. It contributes to increase opportunities for students to improve their science achievement, and for teachers and administrators to make efficient, evidence-based decisions about high-quality teaching and learning.

A key research question guides this effort: How automated scoring of inquiry assessments can increase success for diverse students, improve teachers' instructional practices, and inform administrators' decisions about professional development, inquiry instruction, and assessment? To develop science inquiry assessment activities, scoring written responses include semantic, syntax, and structure of meaning analyses, as well as calibration of human-scored items with a computer-scoring system through the c-rater--an ETS-developed cyber learning technology. Validity studies are conducted to compare automated scores with human-scored items, teacher, district, and state scores, including sensitivity to the diverse student population. To customize the WISE curriculum, the project modifies 12 existing units and develops nine new modules. To design adaptive feedback to students, comparative studies explore options for adaptive guidance and test alternatives based on automated scores employing linear models to compare student performance across randomly assigned guidance conditions; controlling for covariates, such as prior science scores, gender, and language; and grouping comparison studies. To design teacher professional development, synthesis reports on auto-scored data are created to enable them to use evidence to guide curricular decisions, and comments' analysis to improve feedback quality. Workshops, classroom observations, and interviews are conducted to measure longitudinal teachers' change over time. To empower administrators' decision making, special data reports, using-evidence activities, individual interviews, and observation of administrators' meetings are conducted. An advisory board charged with project evaluation addresses both formative and summative aspects.

A research-informed model to improve science teaching and learning at the middle school level through cyber-enabled assessment is the main outcome of this effort. A total of 21 new, one- to three-week duration standards-based science units, each with four or more automatically scored items, serve as prototypes to improve students' performance, teachers' instructional approaches, and administrators' school policies and practices.

CAREER: Engaging Elementary Students in Data Analysis Through Study of Physical Activities

This project is investigating the learning that can take place when elementary school students are directly involved in the collection, sense-making, and analysis of real, personally-meaningful data sets. The hypotheses of this work are that by organizing elementary statistics instruction around the study of physical activities, students will have greater personal engagement in data analysis processes and that students will also develop more robust understandings of statistical ideas.

Full Description: 

This CAREER awardee at Utah State University is investigating the learning that can take place when elementary school students are directly involved in the collection, sense-making, and analysis of real, personally-meaningful data sets. The project responds to increasing attention to data collection and analysis in elementary grades and aims to make important contributions to the knowledge base on effective approaches to these topics. The hypotheses of this work are that by organizing elementary statistics instruction around the study of physical activities, students will have greater personal engagement in data analysis processes and that students will also develop more robust understandings of statistical ideas. Students and teachers from fifth grade classrooms from several elementary schools from northern Utah, are participating in the project. This work is co-funded by the EPSCoR program.

Statistics topics include measures of center and variation. Students use pedometers, heart rate monitors, other probeware, and the TinkerPlots software. The research team investigates the influence of personal ownership and relationships to data on students' understanding of learning of elementary statistics concepts and their ability to analyze data. The research involves multi-year clinical interviews and video-recorded classroom design experiments.

Research results are expected to be published in appropriate journals and are expected to be presented at professional meetings. Lesson plans and student instructional materials related to physical activity, measures of center, and data distributions are made available for use in partner elementary schools.

Enhancing Games with Assessment and Metacognitive Emphases (EGAME)

This development and research project designs, develops, and tests a digital game-based learning environment for supporting, assessing and analyzing middle school students' conceptual knowledge in learning physics, specifically Newtonian mechanics.

Full Description: 

This development and research project from Vanderbilt University, Facet Innovations, and Filament Games, designs, develops, and tests a digital game-based learning environment for supporting, assessing and analyzing middle school students' conceptual knowledge in learning physics, specifically Newtonian mechanics. This research integrates work from prior findings and refines computer assisted testing and Hidden Markov Modeling to develop a new methodology to engage students in deep learning while diagnosing and scaffolding the learning of Newtonian mechanics.

The project uses a randomized experimental 2 x 1 design comparing a single control condition to a single experimental condition with multiple iterations to test the impact of the game on the learning of Newtonian physics. Using designed based research with teachers and students, the researchers are iteratively developing and testing the interactions and knowledge acquisition of students through interviews, pre and post tests and stealth assessment. Student learner action logs are recorded during game-play along with randomized student interviews. Students' explanations and game-play data are collected and analyzed for changes in domain understanding using pre-post tests assessment.

The project will afford the validation of EGAME as an enabler of new knowledge in the fields of cognition, conceptual change, computer adaptive testing and Hidden Markov Modeling as 90 to 300 middle school students learn Newtonian mechanics, and other science content in game-based learning and design. The design of this digital game platform encompasses a very flexible environment that will be accessible to a diverse group of audiences, and have a transformational affect that will advance theory, design and practice in game-based learning environments.

Implementing the Mathematical Practice Standards: Enhancing Teachers' Ability to Support the Common Core State Standards

This is a four-year project that is producing materials designed to help teachers see how the mathematical practices described in the Common Core State Standards for mathematics can be implemented in mathematics instruction. The goal of the improved instruction is to help students adopt and value these critical mathematical practices.

Full Description: 

The Implementing Mathematical Practices Standards (IMPS) is a four-year project that is producing materials designed to help teachers see how the mathematical practices described in the Common Core State Standards for mathematics can be implemented in mathematics instruction. The goal of the improved instruction is to help students adopt and value these critical mathematical practices. Researchers at the Education Development Center are developing videos and print materials that exemplify the mathematical practices and are working with teachers in grades 5-10 to help them use the materials effectively. The research questions of the project are focused on what features of the materials are most helpful to teachers and what professional development characteristics facilitate implementation of the mathematics practices in classroom instruction. The external evaluation of the project is being conducted by evaluators at TERC who are looking the process of developing materials and how the materials are used.

The materials will include professionally-produced videos exemplifying a particular mathematical practice being implemented in a classroom as well as printed dialogues that are designed to help teachers understand the practice and why it is critical for students to acquire that mathematical practice. The exemplars of mathematical practices are being developed based on pilot work and systematic advice from mathematicians, mathematics educators and mathematics teachers in grades 5-10. The design process is iterative and materials are refined based on feedback that is received. Facilitators are being prepared to conduct professional development and materials are being tested by more than 150 teachers in a variety of school districts.

Professional groups such as NCTM and NCSM have called for materials that exemplify the CCSS mathematical practices. They have argued that teachers need to understand how these standards can be achieved in classrooms. IMPS systematic effort to design materials that exemplify the standards and to test not only the materials but also the professional development associated with the materials is responding to the national need. The videos and dialogues will be available through broad dissemination.

Full Description: 

Developers and researchers at Ohio State University and KCP Technologies are creating, testing, refining, and studying a computer-based, individualized, interactive learning system for intermediate/middle school students that can be used by them independently (online or offline) or by teachers in classrooms. This learning system is called Individualized Dynamic Geometry Instruction (iDGi) and will contain four instructional modules in geometry and measurement that reflect the recommendations of the Common Core State Standards (CCSS). iDGi courseware fully integrates research-based Learning Progressions (LPs) for guiding students' reasoning; formative-assessment linked to LPs; instructional sequencing that interactively adapts to students' locations in LPs; built-in student monitoring, feedback, and guidance; and research-based principles of educational media into the modules. The software platform for iDGi development is an extended version of the dynamic geometry computer environment, The Geometer's Sketchpad.

The development process follows recommendations in Douglas Clements' Curriculum Research Framework and includes sequences of development, trials with students, data collection, and revision. The research and evaluation are based on random assignment of approximately 350 students to treatment and control groups. Achievement data are collected using developer-constructed instruments with items that reflect the mathematics topics in the CCSS. Researchers explore the variability at the student, teacher, and school levels using the appropriate level of hierarchical linear models.

Commercial publishers have expressed strong interest in publishing online and offline computer versions of iDGi, an iPad version of iDGi, an online management system for iDGi, and support materials for users and teachers.

Full Description: 

Research on student learning has developed separate progressions for scientific argumentation, explanation and scientific modeling. Engaging Learners in Scientific Practices develops a learning progression that characterizes how learners integrate and interrelate scientific argumentation, explanation and scientific modeling, building ever more sophisticated versions of practice over time using the three common elements of sense-making, persuading peers and developing consensus. The learning progression is constructed through improvements in students' performance and understanding of scientific practice as measured by their attention to generality of explanation, attention to clarity of communication and audience understanding, attention to evidentiary support, and attention to mechanistic versus descriptive accounts. The project is led by researchers at Northwestern University, the University of Texas, Wright State University, Michigan State University, and the BEAR assessment group. Two cohorts of 180 students each are followed for two years from 4th to 5th grade in Illinois and two cohorts of 180 students each are followed for two years from 5th to 6th grade in Michigan The elementary school students will work with FOSS curriculum units modified to embed supports for scientific practices. Two cohorts of 500 middle school students are followed for three years from 6th to 8th grade as they work with coordinated IQWST units over three years. The outcome measures include analyses of classroom discourse, pre- and pos-test assessments of student learning, and reflective interviews grounded in students' own experiences with practices in the classroom to assess their growth across the dimensions. The BEAR team is responsible for validation and calibration of the frameworks and instruments, and design of the scheme for analysis of the data. Horizon Research performs the formative and summative evaluation. The project will produce an empirically-tested learning progression for scientific practices for grades 4-8 along with tested curriculum materials and validated assessment items that support and measure students' ability in the scientific practices of explanation, argumentation and modeling. In the process of development, an understanding is gained about how to design and test this learning progression. The framework is articulated on a website for use by other researchers and developers. The project also builds capacity by educating several graduate students.

Full Description: 

The research project continues a collaboration between MIT's Center for Educational Computing Initiatives and TERC focusing on the enhancement of K-12 STEM math and science education by means of technology that supports (1) creation of what are termed "ink inscriptions"--handwritten sketches, graphs, maps, notes, etc. made on a computer using a pen-based interface, and (2) in-class communication of ink inscriptions via a set of connected wireless tablet computers. The project builds on the PIs' prior work, which demonstrated that both teachers and students benefit from such technology because they can easily draw and write on a tablet screens, thus using representations not possible with only a typical keyboard and mouse; and they can easily send such ink inscriptions to one another via wireless connectivity. This communication provides teachers the opportunity to view all the students' work and make decisions about which to share anonymously on a public classroom screen or on every student's screen in order to support discussion in a "conversation-based" classroom. Artificial intelligence methods are used to analyze ink inscriptions in order to facilitate selection and discussion of student work.

The project is a series of design experiments beginning with the software that emerged from earlier exploratory work. The PIs conduct two cycles of experiments to examine how tablets affect students learning in 4th and 5th grade mathematics and science. The project research questions and methods focus on systematic monitoring of teachers' and students' responses to the innovation in order to inform the development process. The PIs collect data on teachers' and students' use of the technology and on student learning outcomes and use those data as empirical evidence about the promise of the technology for improving STEM education in K-12 schools. An external evaluator uses parallel data collection, conducting many of the same research activities as the core team and independently providing analysis to be correlated with other data. His involvement is continuous and provides formative evaluation reports to the project through conferences, site visits, and conference calls.

The primary products are substantiated research findings on the use of tablet computers, inscriptions, and networks in 4th and 5 grade classrooms. In addition the PIs develop models for teacher education and use, and demonstrate the utility of artificial intelligence techniques in facilitating use of the technology. With the addition of Malden Public Schools to the list of participating districts, which includes Cambridge Public Schools and Waltham Public Schools from earlier work, the project expands the field test sites to up 20 schools' classrooms.

CAREER: Supporting Middle School Students' Construction of Evidence-Based Arguments

Doing science requires that students learn to create evidence-based arguments (EBAs), defined as claims connected to supporting evidence via premises. In this CAREER project, I investigate how argumentation ability can be enhanced among middle school students. The project entails theoretical work, instructional design, and empirical work, and involves 3 middle schools in northern Utah and southern Idaho.

Full Description: 

Doing science requires that students learn to create evidence-based arguments (EBAs), defined as claims connected to supporting evidence via premises. The question chosen for study by a new researcher at Utah State University is: How can argumentation ability be enhanced among middle school students? This study involves 325 middle school students in 12 class sections from 3 school districts in Utah and Idaho. First, students in middle school science classrooms will be introduced to problem-based learning (PBL) units that allow them to investigate ill-structured science problems. These activities provide students with something about which to argue: something that they have explored personally and with which they have grappled. Next, they will construct arguments using a powerful computer technology, the Connection Log, developed by the PI. The Connection Log provides a scaffold for building arguments, allowing each student to write about his/her reasoning and compare it to arguments built by peers. The study investigates how the Connection Log improves the quality of students' arguments. It also explores whether students are able to transfer what they have learned to new situations that call for argumentation.

This study is set in 6th and 7th grade science classrooms with students of diverse SES, ethnicity, and achievement levels. The Connection Log software supports middle school students with written prompts on a computer screen that take students through the construction of an argument. The system allows students to share their arguments with other members of their PBL group. The first generation version of the Connection Log asks students to:

1. define the problem, or state the problem in their own words

2. determine needed information, or decide on evidence they need to find to solve the problem

3. find and organize needed information

4. develop a claim, or make an assertion stating a possible problem solution

5. link evidence to claim, linking specific, relevant data to assertions

The model will be optimized through a process of design-based research. The study uses a mixed methods research design employing argument evaluation tests, video, interviews, database information, debate ratings, and a mental models measure, to evaluate student progress.

This study is important because research has shown that students do not automatically come to school prepared to create evidence-based arguments. Middle school students face three major challenges in argumentation: adequately representing the central problem of the unit; determining and obtaining the most relevant evidence; and synthesizing gathered information to construct a sound argument. Argumentation ability is crucial to STEM performance and to access to STEM careers. Without the ability to formulate arguments based upon evidence, middle school students are likely to be left out of the STEM pipeline, avoid STEM careers, and have less ability to critically evaluate and understand scientific findings as citizens. By testing and refining the Connection Log, the project has the potential for scaling up for use in science classrooms (and beyond) throughout the United States.

Full Description: 

Computer access has opened an exciting new dimension for STEM education; however, if computers in the classroom are to realize their full potential as a tool for advancing STEM education, methods must be developed to allow them to serve as a bridge across the STEM disciplines. The goal of this 60-month multi-method, multi-disciplinary ICAC project is to develop and test a program to increase the number of students in the STEM pipeline by providing teachers and students with curricular training and skills to enhance STEM education in elementary schools. ICAC will be implemented in an urban and predominantly African American school system, since these schools traditionally lag behind in filling the STEM pipeline. Specifically, ICAC will increase computer proficiency (e.g., general usage and programming), science, and mathematics skills of teachers and 4th and 5th grade students, and inform parents about the opportunities available in STEM-centered careers for their children.

The Specific Aims of ICAC are to:

SA1. Conduct a formative assessment with teachers to determine the optimal intervention to ensure productive school, principal, teacher, and student participation.

SA2. Implement a structured intervention aimed at (1) teachers, (2) students, and (3) families that will enhance the students’ understanding of STEM fundamentals by incorporating laptops into an inquiry-based educational process.

SA3. Assess the effects of ICAC on:

a. Student STEM  engagement and performance.

b. Teacher and student computing specific confidence and utilization.

c. Student interest in technology and STEM careers.

d. Parents’ attitudes toward STEM careers and use of computers.

To enable us to complete the specific aims noted above, we have conducted a variety of project activities in Years 1-3. These include:

  1. Classroom observations at the two Year 1 pilot schools
  2. Project scaling to 6 schools in Year 2 and 10 schools in Year 3
  3. Semi-structured school administrator interviews in schools
  4. Professional development sessions for teachers
  5. Drafting of curriculum modules to be used in summer teacher institutes and for dissemination
  6. In-class demonstration of curriculum modules
  7. Scratch festivals each May
  8. Summer teacher institutes
  9. Student summer camps
  10. Surveying of teachers in summer institutes
  11. Surveying of teachers and students at the beginning and end of the school year
  12. Showcase event at end of student workshops

The specific ICAC activities for Years 2-5 include:

  • Professional development sessions (twice monthly for teachers), to integrate the ‘best practices’ from the program.
  • Working groups led by a grade-specific lead teacher. The lead teacher for each grade in each school will identify areas where assistance is needed and will gather the grade-specific cohort of teachers at their school once every two weeks for a meeting to discuss the progress made in addition to challenges to or successes in curricula development.  
  • ICAC staff and prior trained teachers will visit each class monthly during the year to assist the teachers and to evaluate specific challenges and opportunities for the use of XOs in that classroom.  
  • In class sessions at least once per month (most likely more often given feedback from Teacher Summer Institutes) to demonstrate lesson plans and assist teachers as they implement lesson plans.
  • ICAC staff will also hold a joint meeting of administrators of all target schools each year to assess program progress and challenges. 
  • Teacher Summer Institutes – scaled-up to teachers from the new schools each summer to provide training in how to incorporate computing into their curriculum.
  • Administrator sessions during the Teacher Summer Institutes; designed to provide insight into how the laptops can facilitate the education and comprehension of their students in all areas of the curriculum, discuss flexible models for physical classroom organization to facilitate student learning, and discussions related to how to optimize the use of computing to enhance STEM curricula in their schools.  Student Summer Computing Camps – designed to teach students computing concepts, make computing fun, and enhance their interest in STEM careers.  
  • ICAC will sponsor a yearly showcase event in Years 2-5 that provides opportunities for parents to learn more about technology skills their children are learning (e.g., career options in STEM areas, overview of ICAC, and summary of student projects). At this event, a yearly citywide competition among students also will be held that is an expanded version of the weeklong showcase event during the student summer camps.
  • Surveying of students twice a year in intervention schools.
  • Surveying of teachers at Summer Institutes and then at the end of the academic year.
  • Coding and entry of survey data; coding of interview and observational data.
  • Data analysis to examine the specific aims (SA) noted above:
    • The impact of ICAC on teacher computing confidence and utilization (SA 3.b).
    • Assess the effects of (1) teacher XO training on student computing confidence and utilization (SA 3.b), (2) training on changes in interest in STEM careers (SA 3.c), and (3) XO training on student engagement (SA 3.a).
    • A quasi-experimental comparison of intervention and non-intervention schools to assess intervention effects on student achievement (SA 3.a).
    • Survey of parents attending the yearly ICAC showcase to assess effects on parental attitudes toward STEM careers and computing (SA 3.d).

The proposed research has the potential for broad impact by leveraging technology in BCS to influence over 8,000 students in the Birmingham area. By targeting 4th and 5th grade students, we expect to impact STEM engagement and preparedness of students before they move into a critical educational and career decision-making process. Further, by bolstering student computer and STEM knowledge, ICAC will impart highly marketable skills that prepare them for the 81% of new jobs that are projected to be in computing and engineering in coming years (as predicted by the US Bureau of Labor Statistics).3 Through its formative and summative assessment, ICAC will offer intellectual merit by providing teachers throughout the US with insights into how computers can be used to integrate the elementary STEM curriculum. ICAC will develop a model for using computers to enhance STEM education across the curriculum while instilling a culture among BCS schools where computing is viewed as a tool for learning.

Full Description: 

Researchers at the Universities of Michigan and Maryland are developing materials to survey the rationality behind secondary mathematics teaching practice and to support the development by secondary mathematics preservice teachers of specialized knowledge and skills for teaching. The project focuses on the leading of classroom discussions for the learning of algebra and geometry.

Using animations of instructional scenarios, the project is developing online, multimedia questionnaires and using them to assess practicing teachers' mathematical knowledge for teaching and their evaluations of teacher decision making. Reports and forum entries from the questionnaires are integrated into a learning environment for prospective teachers and their instructors built around these animated scenarios. This environment allows pre-service teachers to navigate, annotate, and communicate about the scenarios; and it allows their instructors to plan using those scenarios and share experiences with their counterparts.

The research on teachers' rationality uses an experimental design with embedded one-way ANOVA, while the development of the learning environment uses a process of iterative design, implementation, and evaluation. The project evaluation by researchers at Northwestern University uses qualitative methods to examine the content provided in the environment as well as the usefulness perceived by teacher educators of a state network and their students.
