The NSTA Learning Center desires to showcase the real impact teachers and students
achieve when experiencing our high quality resources and experiences as part of
their personalized learning, whether as an individual or as part of a blended professional
development experience at the district or state level. Below you will find links to several peer-reviewed publications, a third-party independent evaluation, and several recent presentations that share our research and story:

Abstract: Teaching, unlike many other professions, is a largely isolated
occupation in that teachers spend the majority of their work day instructing classes
on their own, with limited time available to interact with their peers and share
and develop knowledge. In urban areas, competing demands on teachers leave little
time to develop a sustaining learning community within a school. In rural areas,
teachers' opportunities to collaborate with colleagues are additionally constrained
by limited numbers of peers and high turnover. We expect that feelings of isolation
are intensified for K-12 science teachers, as their number within a school tends
to be smaller than other content area teachers (e.g., math and language arts), and
there may be few or no colleagues within the same science domain. The need for interaction
and collegiality among science educator peers might, in principle, be met through
attendance at in-person professional society meetings or PD events, but science
teachers report lacking adequate local opportunities for such activity. Online communities
of practice (CoPs) appear to afford promising alternatives for overcoming the absence
of collocated peers in science education. This study explores how web-based collaboration
technologies are used to build distributed communities of practice (CoP) among science
educators. We focus on CoPs among science educators due to increasing national attention
on science, technology, engineering, and math (STEM) education, the potential for
web technologies to support teachers who often lack physically co-located colleagues,
and the very limited research on CoPs in this domain. This presentation addresses
how participation in virtual CoP activities leads to the generation of situated
knowledge and sociotechnical capital and factors that are associated with participation
in these communities. Data analysis is in progress.

Role for Learning Analytics in Online Communities of Practice Supporting Teacher
Learning. Hawaii International Conference on System Sciences, January, 2012,
Maui, Hawaii. Perez-Lopez, K; Cambridge, D; Byers, A.
Abstract: Prior research has demonstrated that the quality of moderation and management in
online communities of practice is key to their successful support of learning. However,
as communities grow in size and complexity, it becomes increasingly difficult for
unaided experts to fully understand and take action in response to the activity
of participants within them. Learning analytics has the potential to provide the
support that community of practice leaders need to improve their performance. The
National Science Teachers Association and U.S. Department of Education’s Connected
Educators project are exploring three approaches for managing forums to make them
accessible and to synthesize the knowledge they generate: archiving, summarizing,
and reorganizing. This paper describes manual heuristics for the first two of these,
as well as the use of social network analysis to help develop algorithms to automate
the third, community forum reorganization.
- First steps towards a social learning analytics for online communities
of practice for educators. Learning Analytics and Knowledge 2012, Vancouver,
Abstract: Learning analytics has the potential to provide actionable insights
for managers of online communities of practice. Because the purposes of such communities
and the patterns of activity that might further them are diverse, a wider range
of methods may be needed than in formal educational settings. This paper describes
the proposed learning analytics approach of the U.S. Department of Education's Connected
Online Communities of Practice project, and presents preliminary applications of
social network analysis to the National Science Teachers Association Learning Center
as an illustration. Authors: Cambridge, D., Perez-Lopez, K.
- Developing a Web-Based Mechanism for Assessing Teacher Science Content Knowledge
of Science Teacher Education, 22 (1), March 2011. Authors: Byers, A.; Koba, S.; Sherman, G.; Scheppke, J.; Bolus, R.
Abstract: The National Science Teachers Association (NSTA) recently launched
a comprehensive electronic professional development (e-PD) online portal, the NSTA
Learning Center. This support site for educators currently includes over 4,000 e-PD
resources and opportunities available on-demand, as well as various tools designed
to help educators maximize the effectiveness of using NSTA resources. One tool,
the PD Indexer, helps teachers identify their own areas of content strengths and
weaknesses by selecting content-specific assessments. Individual NSTA resources
are recommended based on assessment outcomes. This paper presents a detailed description
of the procedures employed by NSTA to develop valid and reliable PD Indexer content-specific
multiple-choice assessment items. Authors: Byers, A.S., Koba, S., Sherman, G., Scheppke,

- Electronic portfolios in the professional development of educators. In D'agustino
Steven (Ed.), Adaptation, Resistance, and Access to Instructional Technologies:
Assessing Future Trends in Education (pp. 429-444). Sherman, G., & Byers,
Abstract: This chapter presents an overview of current electronic portfolio
options available to practicing educators, emphasizing the different roles portfolios
play within the professional development process. Available features within a variety
of free and subscription web-based portfolio services are compared and the use of
specific portfolio options within different professional development environments
such as university graduate programs are profiled. Using a case study-like approach,
the chapter details the use of the National Science Teachers Association’s (NSTA)
Learning Center, a collection of resources available to teachers that includes a
web-based professional development plan and portfolio tool. The chapter concludes
with a reflection on the different ways in which professional organization resources
like the NSTA’s PD Plan and Portfolio Tool can be used in the near future to continually
improve the professional practice of educators.
- Evaluation of online, on-demand science professional development material involving
two different implementation models. Journal of Science Education and Technology, 17(1), pp.
Abstract: This report presents pilot-test results for a science professional
development program featuring online, on-demand materials developed by the National
Science Teachers Association. During the spring 2006 semester, 45 middle school
teachers from three different school districts across the United States participated
in a professional development program designed to facilitate content knowledge and
skills in the area of Newtonian force and motion. Participants from one of the school
districts experienced a full-day instructor-led workshop along with two web-based
seminars with a content-area expert. This was followed by a 4-week period of time
in which they had access to self-directed, online, on-demand instructional materials
that included activities, information, simulations, examples, and practice with
immediate feedback over the targeted outcomes. Participants from the two other school
districts only had access to the online materials with no instructor-led experience.
This report documents positive gains in achievement as well as levels of confidence
in teaching the material within all of the professional development groups. Data
about the use of specific features within the online material are included, as well
as completion rates and attitude survey results. Recommendations for future study
are also included. Authors: Sherman, G., Byers, A., Rapp, S.

Edvantia conducted a two pretest-posttest delayed-treatment control
group design study involving random assignment of two of NSTA’s SciPacks (online
web modules focused on Earth’s Changing Surface and Force and Motion). This study
examined the extent to which middle school teachers in the Houston Independent School
District used two of the Learning Center’s SciPacks, and the SciPacks’ impact on
teacher science teaching efficacy, teacher and student content knowledge in earth
science and force and motion, and teacher instructional practices.
Survey results indicate that teachers’ sense of efficacy for teaching science increased
over the course of the study, which suggests positive effects of the online professional
development experience. Further, teachers who completed at least two SciPacks significantly
increased their perceived preparedness to teach earth science over the course of
the study. Teachers’ content knowledge of earth science and force and motion was
examined by embedded SciPack final assessments, and pre- and post-assessments. Assessment
scores indicated that teachers significantly increased their content knowledge in
both content areas. Teachers improved their scores over time almost equally for
both earth science and force and motion. Further, treatment teachers achieved higher
gain scores than control teachers in both content areas.
Students of participating teachers did, indeed, improve their performance in earth
science or force and motion. Fifth-grade students in the treatment teachers’ classrooms
scored significantly higher on an earth science assessment than did those in control
teachers’ classrooms, suggesting that the SciPacks had a positive impact on student
performance in earth science. In addition, 6th- and 8th-grade students of treatment
group teachers had gain scores that were significantly larger than the gain scores
of students in control teachers’ classrooms, again suggesting that teacher SciPack
completion had a positive influence on their students’ knowledge of force and motion.

evaluation findings of the first two years of the IDEA project. Download the summary report
. Download the slide presentation
This NASA grant supported middle and high school teachers representing
13 school districts via a blended model of teacher professional development combining
both synchronous and asynchronous experiences via the NSTA Learning Center with
local face-to-face PD efforts. Goals include increasing teacher content knowledge
and pedagogical effectiveness and increasing student interest in Earth/Space Science
and STEM career opportunities, as well as exploring which features of blended PD
affordances best supported teacher learning preferences. After completing pre/post
knowledge tests, teachers’ scores significantly increased more than 20 percentage
points. Teachers confirmed the value of online community engagement to support their
learning. Students who participated in project activities were much more likely
to agree with the item, I am likely to take extra science, engineering, or math
courses in high school that are beyond what is required.
