Service Learning as Scholarship in Teacher Education

This article describes how two teacher education service-learning programs illustrate alternative interpretations of scholarship. A tutoring-mentoring program in a teaching oriented masters institution and a motor skill development program in a land grant doctoral-research institution are described relative to how each illustrates forms of scholarship as interpreted by Boyer ( 1990). We discuss how these forms of scholarship the scholarship of discovery, integration, teaching, and application--relate to stated institutional mission and evaluation practices. Service-learning experiences for preservice teachers can have the multiple benefits of promoting an ethic of service and social responsibility, demonstrating excellence in teacher education, and exemplifying scholarly endeavors

Look, Think, Act: Using Critical Action Research to Sustain Reform in Complex Teaching/Learning Ecologies

This paper argues that educators interested in sustainability should look to complexity science for guiding principles. When we view our classrooms and campuses as living, dynamic ecologies, we can, as insiders, make sense of what might otherwise seem chaotic or meaningless. This perspective enables us not only to describe and explain what is happening around us, but also to use our findings to influence emerging patterns across our classrooms, campuses, or our larger communities. We suggest that educators use a Look, Think, Act cycle recommended by Ernie Stringer to encourage and support sustainable school reform

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
