An evaluation of an experimental biology course employing some cognitive and noncognitive achievements as criteria

Creator:: Durst, Harold Everett
Abstract:: This study was designed to evaluate the relative effectiveness of a new college general biology course which utilized an audio - tutorial laboratory as contrasted with a traditional lecture course. Five biology classes with 720 students at the Kansas State Teachers College in Emporia, Kansas, participated in the study. The...

A determination and selection of a biology course content of significance for a freshman level general education course

Creator:: Hankins, Lela Ruth
Abstract:: The purposes of this investigation were twofold: 1. To determine important criteria for making a selection of course content in general biology. 2. To ascertain what should be the content emphasis in biology for the purposes of general education at the freshman college level. The literature pertinent to the problem...

Respiratory adaptations of two macrurousanomuran mud shrimps, Callianassa Califormiensis and Upogebia pugettensis (Decapoda, Thalassinidea)

Creator:: Thompson, Rogene Kasparek
Abstract:: Callianassa californiensis Dana and Upogebia pugettensis (Dana) inhabit estuarine mudflats and are subjected to the hypoxic conditions that prevail during tidal exposure. Metabolic responses for both these species, as indicated by critical oxygen tension, metabolic rate, and tolerance to anoxia were determined. An oxygen macro-electrode and a physiological gas analyzer...

Toxigenic and non-toxigenic strains of Clostridium botulinum type E : A. Differentiation by immunodiffusion : B. Attempts to induce toxigenicity by mutagenic agents

Creator:: Balstraz, Edwina Gene
Abstract:: In this study of toxigenic and non-toxigenic strains of Clostridium botulinum type E, attempts were made to induce toxin production in non-toxigenic cultures by exposure to mutagenic agents and to differentiate the organisms by immunodiffusion. First, cultures of non-toxic Cl. botulinum type E were exposed to various mutagenic agents in...

Physiological ecology and structure of benthic communities in a woodland stream

Creator:: Reese, Weldon Harold
Abstract:: This thesis reports a portion of a general ecological study of a stream under conditions of controlled flow and low levels of organic enrichment. It is concerned with the effects of experimental variations of light intensity and concentration of soluble organic enrichment imposed on seasonal variations of temperature and total...

Isolation of auxotrophic mutants of Bacillus cereus

Creator:: Keng, Jiun Guang
Abstract:: Bacillus cereus excretes large amounts of penicillinase into growth media during incubation, hence the widely-used penicillin selection technique for isolating biochemical mutants of bacteria is not applicable to this species. Genetic transfer in B. cereus has not been reported; this is partly due to the lack of an effective isolation...

Metabolism of periphyton communities in two small streams

Creator:: Lane, Charles Bertell
Abstract:: A technique for estimating gross primary production and respiration of periphyton communities, in situ, in small turbulent streams was developed using a photosynthesis-respiration chamber in a modified "light and dark bottle" method. Trays containing portions of the substrate bearing the benthic community were embedded in the stream, level with the...

Student performance in lower division collegiate general biology programs in selected community colleges and four-year institutions in Oregon

Creator:: Tolman, Richard Robins
Abstract:: It was the intent of this investigation to compare the performance of community college students to four-year institutional students, both of whom were enrolled in a college general biology program (GS 101, 102, 103) during the 1967-68 academic year. During the week of May 27, 1968 measurements were taken of...

Change in critical thinking between students in laboratory-centered and lecture-demonstration-centered patterns of instruction in high school biology

Creator:: Sorensen, Lavar Leonard
Abstract:: This investigation was designed to analyze change in critical . thinking between students in laboratory-centered and lecture-demonstration-centered patterns of instruction in high school biology. Twenty biology classes were randomly selected from the four senior high schools in the Salt Lake City School District. Class enrollment ranged from nine students in...
