    Math and Science Education

    Resnick provides an excellent brief account of current work in cognitive psychology and its important implications for math and science education. As she indicates, most cognitive psychologists view knowledge as consisting of highly organized schemata into which new experiences are assimilated and view the learner as actively constructing new knowledge. This view is consistent with the ideas that Piagetian theorists and educators have been propounding for many years, although Resnick’s discussion is rooted in the more detailed analysis of specific knowledge and learning in specific content areas that typifies the information-processing paradigm of modern cognitive science

    Supportive technologies for group discussion in MOOCs

    A key hurdle that prevents MOOCs from reaching their transformative potential in terms of making valuable learning experiences available to the masses is providing support for students to make use of the resources they can provide for each other. This paper lays the foundation for meeting this challenge by beginning with a case study and computational modeling of social interaction data. The analysis yields new knowledge that informs design and development of novel, real-time support for building healthy learning communities that foster a high level of engagement and learning. We conclude by suggesting specific areas for potential impact of new technology

    Beyond summative evaluation: The Instructional Quality Assessment as a professional development tool

    Get PDF
    In order to improve students' opportunities to learn, educators need tools that can assist them to reflect on and analyze their own and others' teaching practice. Many available observation tools and protocols for studying student work are inadequate because they do not directly engage educators in core issues about rigorous content and pedagogy. In this conceptual paper, we argue that the Instructional Quality Assessment (IQA)--a formal toolkit for rating instructional quality that is based primarily on classroom observations and student assignments--has strong potential to support professional development within schools at multiple levels. We argue that the IQA could be useful to "teachers" for analyzing their own and their colleagues' practice; additionally, the IQA could aid the efforts of "principals" in their work as instructional leaders, identifying effective practitioners to help lead professional development within a school and targeting professional development needs that would require external support. Although the IQA was designed for summative, external evaluation, we argue that the steps taken to improve the reliability of the instrument--particularly the efforts to make the rubric descriptors for gradations of instructional quality as transparent as possible--also serve to make the tool a resource for professional growth among educators.

    Using the Instructional Quality Assessment toolkit to investigate the quality of reading comprehension assignments and student work (CSE Report 669)

    This study presents preliminary findings from research developing an instructional quality assessment (IQA) toolkit that could be used to monitor the influence of reform initiatives on students' learning environments and to guide professional development efforts within a school or district. This report focuses specifically on the portion of the IQA used to evaluate the quality of teachers' reading comprehension assignments and student work. Results are limited due to a very small sample of participating teachers (N = 13, 52 assignments), and indicate a poor to moderate level of inter-rater agreement and a good degree of consistency for the dimensions measuring academic rigor, but not the clarity of teachers' expectations. The rigor of the assignments collected from teachers also was associated with the rigor of observed instruction. Collecting four assignments (two challenging and two recent) from teachers did not yield a stable estimate of quality. Additional analyses looking separately at the two different assignment types indicate, however, that focusing on one assignment type would yield a stable estimate of quality. This suggests that the way in which assignments are collected from teachers should be revised. Implications for professional development are also discussed. The 2003 Draft Observation and Assignment Rubrics for Reading Comprehension is appended. (Contains 6 tables, 4 figures, and 4 footnotes.

    Pathema: a clade-specific bioinformatics resource center for pathogen research

    Get PDF
    Pathema (http://pathema.jcvi.org) is one of the eight Bioinformatics Resource Centers (BRCs) funded by the National Institute of Allergy and Infectious Disease (NIAID) designed to serve as a core resource for the bio-defense and infectious disease research community. Pathema strives to support basic research and accelerate scientific progress for understanding, detecting, diagnosing and treating an established set of six target NIAID Category A–C pathogens: Category A priority pathogens; Bacillus anthracis and Clostridium botulinum, and Category B priority pathogens; Burkholderia mallei, Burkholderia pseudomallei, Clostridium perfringens and Entamoeba histolytica. Each target pathogen is represented in one of four distinct clade-specific Pathema web resources and underlying databases developed to target the specific data and analysis needs of each scientific community. All publicly available complete genome projects of phylogenetically related organisms are also represented, providing a comprehensive collection of organisms for comparative analyses. Pathema facilitates the scientific exploration of genomic and related data through its integration with web-based analysis tools, customized to obtain, display, and compute results relevant to ongoing pathogen research. Pathema serves the bio-defense and infectious disease research community by disseminating data resulting from pathogen genome sequencing projects and providing access to the results of inter-genomic comparisons for these organisms
