A Teaching Experiment in the Use of Greenhouse Facilities in Vocational Agriculture.
Drawbaugh, Charles Calvin
Major purposes were to measure the comparative effectiveness of school greenhouses, community greenhouses, and classroom windowsills and a laboratory manual, functional experience, and teacher's own method for learning plant science principles relative to the environmental factors of light, temperature, moisture, aeration, and nutrients. Minor purposes were to discover relationships among the environmental factors of plant growth in the application of knowledge, to discover relationships among the environmental factors of plant growth in the application of knowledge, to discover relationships among kinds of crops in the application of knowledge, and to discover the influences of concurrent enrollment in biology. The 27 Pennsylvania schools in the sample were assigned in a balanced design which included three schools in each kind of facility and teaching method category. A random sample of 10 students was drawn from a vocational agriculture class in each school to provide the data. Findings indicated: total achievement in plant science by students using school greenhouses was greater, the teacher's own method of instruction was least effective in knowledge of greenhouse management and plant science principles instruction, and students enrolled in biology did not show a greater difference from pretest to test scores than students not enrolled in biology. This Ed.D. thesis was submitted to The Pennsylvania State University. (DM)
