"A Rale Boost to Lithrachoor": A Humorist Lampoons Libraries
The founders of the great libraries of the 19th century were often ambivalent about whether their goal was to disseminate or conserve knowledge. They were also uncertain about the intended audience. John Cotton Dana of the Newark Public Library was atypical in his populist stance that "it is a proper function of a library to amuse." He argued that a "shallow mind" was better than an "empty one." Other librarians preferred to see themselves as cultivators of public taste and their buildings as up

Fostering computer supported collaborative learning with cooperation scripts and scaffolds
The study investigates collaborative learning of small groups via text-based computer-mediated communication. We analyzed how two approaches to pre-structure communication influence participation, individual knowledge transfer, the convergence of participation and the convergence of knowledge among peers. We varied the factor scripted cooperation and the factor scaffolding in a 2x2-design. 105 university students of Educational Psychology participated. Results show that scripted cooperation was

Evaluating How Our Students Think and Learn: Research Results from the Trenches
This PowerPoint presentation addresses research on the thinking and learning processes of students and how increased knowledge of these processes can be used to structure lectures in a manner that will change the way students learn. It covers methods for course redesign, classroom assessment techniques, levels of learning and goals in general education courses. Among other things, it was found that student success is predictable, all students benefit from active learning, and group work is impor

Designing an Earth System Course
This Starting Point module describes the process of putting together a course in Earth System Science course. Users will find information on what an ESS course is, why this approach is useful and how to actually create the class. This module supports faculty efforts to structure Earth system science education not only to the needs of geoscience majors, but a variety of different audiences, from non-science majors to pre-service teachers.

Daisyworld Stella Activity
Daisyworld model is a very simple planet that has only two species of life on its surface - white and black daisies, and bare ground. Daisyworld is a good example of homeostasis and was first proposed by James Lovelock as a plausible example of his Gaia hypothesis. The Daisyworld activity helps students build a Stella model of Daisyworld from scratch. After constructing the model they perform guided experiments to explore the behavior of Daisyworld to changes in model parameters and assumptions.

Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
