Full Description: 

This project is conducting a longitudinal study of the effects of an innovative pre-service elementary science education program at Western Washington University which was established with support from an NSF MSP grant.

There are four overlapping studies on the pre-service teachers (PSTs) and in-service teachers who are graduates of the program: (1) Comparing the pedagogical beliefs and skills of elementary PSTs as a function of the number (0-3) of reformed science content courses taken; (2) Comparing the same outcome variables for PSTs placed for student teaching with trained or untrained mentor teachers; (3) Comparing the impact of the science methods/practicum on PSTs who experienced the WWU reformed courses and those who did not; (4) An exploratory case study of the instructional practices of 20 novice elementary science teachers. The research utilizes the following existing instruments. (1) CLASS, the Colorado Learning Attitudes on Science Survey, (2) the Horizon Classroom Observation Protocol, (3) the Washington Educator Skills Test-Endorsement, and (4) the Washington State Science Assessment for 5th graders in addition to some instruments developed by the project. Studies 1-3 will each have 45 treatment and 45 control participants. Evaluation is by Horizon Research Inc. It focuses on project progress and effectiveness, which is appropriate for a research project. Its participation will also facilitate the use of the Horizon Classroom Observation Protocol.

The new undergraduate program at WWU has implemented and institutionalized many of the recommendations for best practices in preparing elementary school teachers in science. This project is seeking to analyze the impact of three essential dimensions of teacher preparation: inquiry-based science content courses, science methods/practicum courses, and student teaching.

Full Description: 

This research study is examining the persistence of improved teacher skills achieved during the K-2 Science & Technology Assistance for Rural Teachers and Small Districts project (K-2 STARTS) funded by the State of California.

K-2 STARTS provided four years of professional development to teachers in 16 rural school districts in California with high populations of traditionally underserved students. 39 teachers each received 110 hours of professional development. Project data indicate that the project met its goals by increasing teacher content knowledge, pedagogical content knowledge, abilities to integrate science and literacy and to use research-based instructional strategies. K-2 STARTS also improved the capacity of teachers to use science resources and to network with teachers from their own and other rural districts.

This project is doing a longitudinal research study by extending data collection for 35 teachers for two years after the end of K-2 STARTS. It is using the measures from the original evaluation, which include teacher surveys and interviews, classroom observations, surveys for school administrators, teacher-developed unit artifacts, and student science notebooks, and adding two more measures, administrative interviews and school/district documents. In the final year, the project is doing data analysis and dissemination. The project is exploring the persistence of the knowledge and skills of the teachers over time, as well as their continued use of science instructional practices. It will also study the persistence of school/district support for science education.

External evaluation is being conducted by Dr. Loretta Kelley of Kelley, Peterson, and Associates, Inc. It focuses on project progress through formative and summative components.

Longitudinal studies of the effects of teacher professional development are rare. The increased knowledge concerning the persistence of the new knowledge and skills obtained through K-2 STARTS professional development, and why and to what extent they decay over time, is a significant goal.

Full Description: 

The research goal of this project is to evaluate whether an early childhood science education program, Head Start on Science, implemented in low-income preschool settings (Head Start) produces measurable impacts for children, teachers, and parents. The study is being conducted in eight Head Start programs in Michigan, involving 72 classrooms, 144 teachers, and 576 students and their parents. Partners include Michigan State University, Grand Valley State University, and the 8 Head Start programs. Southwest Counseling Solutions is the external evaluator.

The study is determining the efficacy of the Head Start on Science curriculum in two models, one in which 72 teachers participate in professional development activities (the intervention), and another in which 72 teachers receive the curriculum and teachers' guide but no professional development (the control). The teacher study is a multi-site cluster randomized trial (MSCRT) with the classroom being the unit of randomization. Four time points over two years permit analysis through multilevel latent growth curve models. For teachers, measurement instruments include Attitudes Toward Science (ATS survey), the Head Start on Science Observation Protocol, the Preschool Classroom Science Materials/Equipment Checklist, the Preschool Science Classroom Activities Checklist, and the Classroom Assessment Scoring System (CLASS). For students, measures include the "mouse house problem," Knowledge of Biological Properties, the physics of falling objects, the Peabody Picture Vocabulary Test-Fourth Edition, the Expressive Vocabulary Test-2, the Test of Early Mathematics Ability-3, Social Skills Improvement System-Rating Scales, and the Emotion Regulation Checklist. Measures for parents include the Attitudes Toward Science survey, and the Community and Home Activities Related to Science and Technology for Preschool Children (CHARTS/PS). There are Spanish versions of many of these instruments which can be used as needed. The external evaluation is monitoring the project progress toward its objectives and the processes of the research study.

This project meets a critical need for early childhood science education. Research has shown that very young children can achieve significant learning in science. The curriculum Head Start on Science has been carefully designed for 3-5 year old children and is one of only a few science programs for this audience with a national reach. This study intends to provide a sound basis for early childhood science education by demonstrating the efficacy of this important curriculum in the context of a professional development model for teachers.

The Effectiveness of Inclusive STEM Schools at Scale: A Multistate Longitudinal Quasi-experiment

In this project, investigators are laying the foundation for a rigorous quasi-experiment to test the effects of attending such a school using longitudinal student records, surveys, and interviews. By documenting survey response rates, student location rates, and rates for successful matching of student administrative and survey data, this project is demonstrating that it is possible to collect data that would enable a large-scale study to be launched with the necessary instruments and experience in hand.

Full Description: 

Concerns about both economic competitiveness and educational equity emphasize the need for the United States to broaden and diversify the pipeline of students prepared and motivated to pursue STEM college majors. An emerging strategy for addressing this need is large-scale implementation of inclusive STEM high schools. In this exploratory project, investigators from SRI International and George Washington University are laying the foundation for a rigorous quasi-experiment to test the effects of attending such a school using longitudinal student records, surveys, and interviews. The project's operational definition for an inclusive STEM high school (ISHS) is a school, school within a school, or school program that accepts students primarily on the basis of interest rather than aptitude or prior achievement and gives them the mathematics and science preparation they need to succeed in a STEM college major. ISHSs enroll students from groups underrepresented in STEM professions through an application process that does not require high test scores before high school entry. In contrast to selective STEM schools that admit gifted and talented students on the basis of entrance examination scores and thus select for perceived STEM aptitude, ISHSs have the more ambitious goal of developing STEM expertise.

To establish the feasibility of a large, multi-state investigation of the effectiveness of inclusive STEM schools at scale, researchers are:

- Developing a tentative taxonomy of ISHSs and exploring implications of ISHS heterogeneity for the research design;

- Recruiting three school partners representing different ISHS approaches;

- Using state data to identify a comparison school (without a particular focus on STEM) for each ISHS school partner and recruiting comparison school partners;

- Developing School Leader and three student surveys (fall 9th-grade, spring 12th-grade, and spring post-graduation);

- Collaborating with partner schools in design of data collection procedures, recruiting materials, and incentives;

- Piloting the School Leader Survey and two student surveys (9th-grade fall survey and 12th-grade spring survey) in six partner schools;

- Identifying and recruiting a larger sample of ISHSs and matched comparison schools for Year 2 data collection;

- Administering surveys in 40 or more high schools;

- Locating spring 2012 graduates of the three ISHS partner schools and pilot testing the post-graduation student survey with these students; and

- Engaging an Advisory Board who will provide methodological expertise and advice.

Ultimately, by documenting survey response rates, student location rates, and rates for successful matching of student administrative and survey data, this feasibility work is demonstrating that it is possible to collect the kind of data that would enable a large-scale study to be launched with the necessary instruments and experience in hand. As evidenced by the recent call from the President's Council of Advisors in Science and Technology for 1,000 new STEM schools and the National Research Council's report entitled "Successful K-12 STEM Education: Identifying Effective Approaches in Science, Technology, Engineering, and Mathematics" that highlights various STEM schools, the proposed research is highly relevant to current policy initiatives and debates. Moreover, the research has the potential to promote diversity in the STEM pipeline by influencing policymakers in states and districts that have yet to implement ISHSs at scale.

Further Development and Testing of the Target Inquiry Model for Middle and High School Science Teacher Professional Development (Collaborative Research: Yezierski)

This project scales and further tests the Target Inquiry professional development model. The model involves teachers in three core experiences: 1) a research experience for teachers, 2) materials adaptation, and 3) an action research project. The original program was implemented with high school chemistry teachers, and was shown to result in significant increases, with large effect sizes, in teachers' understanding of science inquiry and quality of instruction, and in science achievement of those teachers' students.

Full Description: 

This project scales and further tests the Target Inquiry (TI) professional development model. The TI model involves teachers in three core experiences: 1) a research experience for teachers, 2) materials adaptation, and 3) an action research project. The original program was implemented with high school chemistry teachers at Grand Valley State University (GVSU), and was shown to result in significant increases, with large effect sizes, in teachers' understanding of science inquiry and quality of instruction, and in science achievement of those teachers' students. The scale-up and further testing would involve adding physics, biology and geology at Grand Valley State University, and implementing the program at Miami University (MU) with chemistry teachers. Three research questions will be studied:

1) How do the three TI core experiences influence in-service high school science teachers' (i) understanding of the nature of science; (ii) attitudes and beliefs about inquiry instruction; and (iii) classroom instructional methods in the derivatives of the TI model?

2) How does teacher participation in TI affect students' process skills (scientific reasoning and metacognition) and conceptual understanding of science in the derivatives of the TI model?

3) What are the challenges and solutions related to implementing TI in science disciplines beyond chemistry and in other regions?

The research design is quasi-experimental and longitudinal, incorporating implementation with research, and using quantitative and qualitative methods blended in a design research framework. A total of 54 middle and high school science teachers are being recruited for the study. The TI group is completing the TI program (N = 27; 15 at GVSU; 12 at MU) while the comparison group (same sizes and locations) is not. The comparison group is matched according to individual characteristics and school demographics. All teachers are being studied, along with their students, for 4 years (pre-program, post-RET, post-MA, post-AR/post-program). TI teachers are taking 15 credits of graduate level science courses over three years, including summers. Courses include a graduate seminar focused on preparing for the research experience, the research experience in a faculty member's science lab during the summer, application of research to teaching, action research project development, adaptation and evaluation of inquiry-focused curricula, and interpretation and analysis of classroom data from action research. Consistent feedback from professional development, teachers, and evaluation, including the previous implementation, contributes to a design-based approach. Teacher factors being studied include nature of science, inquiry teaching knowledge and beliefs, and quality of inquiry instruction. Student factors being studied include scientific reasoning; metacognition, self-efficacy, and learning processes in science; and content knowledge and conceptual understanding. Only established quantitative and qualitative instruments are being used. Quantitative analysis includes between-group comparisons by year on post-tests, with pre-tests as covariates, and multi-level models with students nested with teachers, and teachers within sites, with the teacher level as the primary unit of change. Trends over time between the treatment and comparison groups are being examined. The evaluation is using a combination of pre/post causal comparative quantitative measures and relevant qualitative data from project leaders and participants, as well as from the comparison group, to provide formative and summative evaluation input.

Outcomes of the project include documentation and understanding of the impacts on science teachers' instruction and student outcomes of research experiences for teachers when they are supported by materials adaptation and action research, and an understanding of what it takes to scale the model to different science disciplines and a different site. The project is also producing a website of instructional materials for middle and secondary science.

Full Description: 

The Development of Ambitious and Equitable Mathematics Instruction project is supporting and investigating the implementation of reformed mathematics instruction at the middle school level in two large school districts. Project researchers are asking: What does it take to support mathematics teachers' development of ambitious and equitable instructional practices on a large scale? The project has built on what was learned in a previous, successful project studying the implementation of a middle school mathematics curriculum. The primary goal of the new project is to develop an empirically grounded theory of action for implementing reform at school and district levels. The researchers are investigating reform within a coherent system that focuses on leadership and school-based professional development. In addition, they are facilitating a longitudinal study of the curriculum implementation by continuing the data collection from the original study.

In order to build a theory of action, the project team is synthesizing data from a variety of domains including instructional systems (e.g., curriculum, materials, professional development, support for struggling students, and learning communities), mathematics coaching, networks of teachers, school leadership, and district leadership. Investigators are using a variety of analytic techniques to successfully integrate both quantitative and qualitative data as they seek to understand how school district strategies are playing out in schools and classrooms and how those strategies can be revised in order to improve student learning of mathematics.

An empirically grounded theory of action for implementing reform will help the mathematics education community to implement and to understand the process of reforming mathematics instruction at the middle school level. Many advances in mathematics instruction have been documented within a limited context, but researchers and practitioners need to understand the full range of action necessary to achieve similar successes at a district-wide level. The model developed from this project, in conjunction with longitudinal data, has the potential to guide future reform efforts that seek to provide ambitious and equitable mathematics instruction.

Full Description: 

This project--led by science educators at Michigan State University, the National Geographic Society, the Natural Resource Ecology Laboratory (NREL) at Colorado State University, the Berkeley Evaluation and Assessment Research (BEAR) Center, and AAAS Project 2061, and including schools in California, Colorado, Maryland, Michigan, and Washington--builds on prior efforts with learning progressions, and is focused on key carbon-transforming processes in socio-ecological systems at multiple scales, including cellular and organismal metabolism, ecosystem energetics and carbon cycling, carbon sequestration, and combustion of fossil fuels.

The project uses an iterative design research process to develop and refine a suite of tools for reasoning and test efficacy of those tools in geographically and culturally diverse schools. The project team is:

1. Refining and validating a detailed learning progression framework covering the middle and high school years; ultimately, the framework will describe the development of students' capacity to use fundamental principles such as conservation of matter and energy to reason about carbon-transforming processes at multiple scales.

2. Refining 'Tools for Reasoning' that make hidden scientific principles - matter, energy, and scale - visible to students; the power of these tools lies in their flexible use for different processes, systems, scales, and curricular contexts.

3. Developing and refining flexible teaching strategies that engage students in cognitive apprenticeship in the practices of environmental science literacy: a) inquiry and argumentation, b) explanations and predictions, and c) decision-making about environmental issues.

4. Using and refining existing summative assessments, and developing and testing formative assessment tools; these assessment tools will provide teachers and researchers with immediate information about their students' intellectual resources and will be linked to the learning progression framework.

5. Developing, field testing, and assessing the effectiveness of six middle school and six high school units that use project tools and enact project principles; the units introduce students to fundamental principles, engage them in reasoning about carbon-transforming processes at organismal scale, and at landscape and global scales. Each unit includes a) an online formative assessment and b) activity sequences that use tools for reasoning and teaching strategies.

6. Developing, field testing, and assessing professional development materials in both face-to-face and facilitated online forms; the materials introduce teachers to learning progressions in environmental science literacy, assessment tools, tools for reasoning, teaching strategies, and teaching materials and activities, and also address difficulties that teachers encounter in using learning progressions and enacting teaching strategies.

The primary project outcomes will be coordinated instructional tools that are useful to professionals at all levels in the science education system--classroom teachers, professional developers, and developers of curricula, standards and assessments.

Efficacy Study of Metropolitan Denver's Urban Advantage Program: A Project to Improve Scientific Literacy Among Urban Middle School Students

This is an efficacy study to determine if partnerships among formal and informal organizations demonstrate an appropriate infrastructure for improving science literacy among urban middle school science students. The study aims to answer the following questions: How does participation in the program affect students' science knowledge, skills, and attitudes toward science; teachers' science knowledge, skills, and abilities; and families engagement in and support for their children's science learning and aspirations?

Full Description: 

This is an efficacy study through which the Denver Museum of Nature and Science, the Denver Zoo, the Denver Botanic Gardens, and three of Denver's urban school districts join efforts to determine if partnerships among formal and informal organizations demonstrate an appropriate infrastructure for improving science literacy among urban middle school science students. The Metropolitan Denver Urban Advantage (UA Denver) program is used for this purpose. This program consists of three design elements: (a) student-driven investigations, (b) STEM-related content, and (c) alignment of schools and informal science education institutions; and six major components: (a) professional development for teachers, (b) classroom materials and resources, (c) access to science-rich organizations, (d) outreach to families, (e) capacity building and sustainability, and (e) program assessment and student learning. Three research questions guide the study: (1) How does the participation in the program affect students' science knowledge, skills, and attitudes toward science relative to comparison groups of students? (2) How does the participation in the program affect teachers' science knowledge, skills, and abilities relative to comparison groups of teachers? and (3) How do families' participation in the program affect their engagement in and support for their children's science learning and aspirations relative to comparison families?

The study's guiding hypothesis is that the UA Denver program should improve science literacy in urban middle school students measured by (a) students' increased understanding of science, as reflected in their science investigations or "exit projects"; (b) teachers' increased understanding of science and their ability to support students in their exit projects, as documented by classroom observations, observations of professional development activities, and surveys; and (c) school groups' and families' increased visits to participating science-based institutions, through surveys. The study employs an experimental research design. Schools are randomly assigned to either intervention or comparison groups and classrooms will be the units of analysis. Power analysis recommended a sample of 18 intervention and 18 comparison middle schools, with approximately 72 seventh grade science teachers, over 5,000 students, and 12,000 individual parents in order to detect differences among intervention and comparison groups. To answer the three research questions, data gathering strategies include: (a) students' standardized test scores from the Colorado Student Assessment Program, (b) students' pre-post science learning assessment using the Northwest Evaluation Association's Measures for Academic Progress (science), (c) students' pre-post science aspirations and goals using the Modified Attitude Toward Science Inventory, (d) teachers' fidelity of implementation using the Teaching Science as Inquiry instrument, and (e) classroom interactions using the Science Teacher Inquiry Rubric, and the Reformed Teaching Observation protocol. To interpret the main three levels of data (students, nested in teachers, nested within schools), hierarchical linear modeling (HLM), including HLM6 application, are utilized. An advisory board, including experts in research methodologies, science, informal science education, assessment, and measurement oversees the progress of the study and provides guidance to the research team. An external evaluator assesses both formative and summative aspects of the evaluation component of the scope of work.

The key outcome of the study is a research-informed and field-tested intervention implemented under specific conditions for enhancing middle school science learning and teaching, and supported by partnerships between formal and informal organizations.
