Watters, Christopher – Cell Biology Education, 2005
In this paper, the author reviews recently published videos that depict the roles played by myosin II in contraction of the cortical ring during cellularization and cytokinesis in early development (Royou et al., 2004), by spindle and astral microtubules in regulating the formation of cleavage furrows during the cleavage of primary spermatocytes…

Holmberg, Borje – Open Learning, 1997
Presents a theory of distance education to demonstrate its potential, based on a discussion of the concept of theory in general. Topics include the scope of a theory of distance education, generating hypotheses, descriptive elements and testable hypotheses generated, and the potential and applicability of the theory suggested. (71 references) (LRW)

Levin, Joel R. – Research in the Schools, 1998
Outlines concerns that must be addressed by those who advocate replacing statistical hypothesis-testing with alternative data-analysis strategies. Suggests that commonly recommended alternatives are not perfect and that various hypothesis-testing modifications can be implemented to make the process and its conclusions more credible. Hypothesis…

Bley-Vroman, Robert – Language Learning, 1986
Answers to theoretical questions about the place of input in a formal second language acquisition model are dependent on a distinction between two kinds of learner hypotheses. Type-N hypotheses require "negative evidence" for testing, while Type-P hypotheses are tested on the basis of "positive data" alone. (Author/CB)

Peterson, Nils S.; And Others – Machine-Mediated Learning, 1987
This discussion of teaching science as a design activity emphasizes open-ended problem solving. Highlights include the relationship between teachers and students; hypotheses as solutions; and descriptions of four microworlds, or computer simulations, in chemistry, geography, physiology, and genetics which use graphic interfaces. (LRW)

Streibel, Michael; And Others – Machine-Mediated Learning, 1987
Describes an advice-giving computer system being developed for genetics education called MENDEL that is based on research in learning, genetics problem solving, and expert systems. The value of MENDEL as a design tool and the tutorial function are stressed. Hypothesis testing, graphics, and experiential learning are also discussed. (Author/LRW)
