    Influence of nitrogen, reduced irradience and biostimulants on turfgrass growth, superoxide dismutase content and chlorphyll fluorescence
    Doak, Samuel O. (Virginia Tech, 1996-12-01)
    Biostimulants (BIOS) are non-mineral substances that, when exogenously applied in very small quantities, stimulate the metabolic activity of plants. Past research with biostimulants has not included differing levels of nitrogen fertility or shade as variables. The research presented was designed to explore some interactions between biostimulants and nitrogen fertility on turfgrass grown under several light conditions.

    Technology Integration in an Agriculture Associate’s Degree Program: A Case Study Guided by Rogers’ Diffusion of Innovation
    Westfall-Rudd, Donna M.; Drape, Tiffany A.; Doak, Samuel O.; Guthrie, Joseph; Mykerezi, Pavli K. (North American Colleges and Teachers of Agriculture, 2013-03)
    Using Rogers’ Diffusion of Innovations as a model, the researcher examined technology integration and how the faculty in an Associate’s Degree program chose to integrate technology into the students’ experiences. This case study explored technology integration from a programmatic standpoint using video collection, observations, qualitative interviews and video coding using Noldus Observer©. Video observations were collected on 96 students and two faculty members; interviews were conducted with 10 students, two faculty members and the program director. The data illustrates that faculty are careful when choosing to integrate technology. They consider the priorities of the program leadership team, technology usage in the agriculture industry and students’ comfort with technology when making decisions about integration. The researchers recommend that technology be integrated on a daily basis and be evaluated as a teaching tool; however, technology is not a substitute for an actual teacher.
