In an attempt to redesign science, technology, engineering, and mathematics (STEM) departments to be more inclusive of all student populations, institutions of higher learning are reviewing their programs, policies, and the ways they engage students. The Partnership for Undergraduate Life Sciences Education (PULSE) has been working with STEM departments over the past 10 years to improve the student experience by incorporating evidence-based teaching practices and creating curricula with a deeper focus on conceptual understanding of scientific principles, competencies, and the process of science. PULSE created the PULSE rubrics, a set of five rubrics designed to assist life sciences departments in assessing their implementation of the recommendations of the American Association for the Advancement of Science Vision and Change report in the areas of curriculum, assessment, faculty practice and faculty support, infrastructure, and climate for change.

The work of the appointed Partnership for Undergraduate Life Sciences Education (PULSE) Vision and Change (V&C) Leadership Fellows has focused on the development of programs and resources to support departmental change. In this report, we present a qualitative assessment of several documents generated from the PULSE V&C Leadership Fellow Recognition Team.

This paper reports on the development of the rubrics, their validation, and their reliability in measuring departmental change aligned with the Vision and Change recommendations.

It is expressed in the neural plate and later in the embryonic brain, eyes, and spinal cord.

We have investigated the activity and function of mitogen-activated protein kinase (MAPK) during neural specification in Xenopus. Ectodermal MAPK activity increased between late blastula and midgastrula stages. At midgastrula, MAPK activity in both newly induced neural ectoderm and ectoderm overexpressing the anterior neural inducer noggin was 5-fold higher than in uninduced ectoderm.
