Extensiveness And Perceptions Of Lecture Demonstrations In The High School Chemistry Classroom, Daniel S. Price

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners’ motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along with qualitative data from follow-up interviews and structured correspondence, to determine the extent to which lecture demonstrations are used in high school chemistry instruction, and the perceived effects of viewing such demonstrations on students’ performance on course assignments and on motivation to excel in current and future chemistry courses. Fifty-two randomly selected chemistry …

Is Competition Making A Comeback? Discovering Methods To Keep Female Adolescents Engaged In Stem: A Phenomenological Approach, Kathryn B. Notter

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The decreasing number of women who are graduating in the Science, Technology, Engineering and Mathematics (STEM) fields continues to be a major concern. Despite national support in the form of grants provided by National Science Foundation, National Center for Information and Technology and legislation passed such as the Deficit Reduction Act of 2005 that encourages women to enter the STEM fields, the number of women actually graduating in these fields is surprisingly low. This research study focuses on a robotics competition and its ability to engage female adolescents in STEM curricula. Data have been collected to help explain why young …

DEVELOPMENTAL/REMEDIAL SCIENCES AT COMMUNITY COLLEGES IN FIVE STATES IN THE CENTRAL PART OF THE UNITED STATES

Tricia L. Paramore, Ph.D. University of Nebraska, 2007 Adviser: Alan T. Seagren

Phipps (1998) emphasized interinstitutional collaboration among colleges to share and replicate best practices and ideas as a strategy to improve the effectiveness of developmental/remedial education, but Johnson (2001) noted a lack of communication between science educators and developmental educators. The purposes of this mixed methods study were (a) to identify and examine the characteristics of developmental/remedial sciences as it existed in the 2006-2007 academic year in terms of organization, structure, instructional practices, …

Comparison Of Grade Point Average Of Honor Senior Students And College Of Liberal Arts Senior Students At A Florida University, Iwasan D. Kejawa Ed.D

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

Attrition rates in theHonor College program division of Florida Atlantic University have risen in recent years. It has been determined that even though a higher high school grade point average is required for admission into the honor program of the university, many applicants to the program were under-prepared to asumme the workload demanded of the students by the Honor College. The requirements for admission into the honor program of the Florida Atlantic University is an overall high school grade point average of 3.5 and a score of 1000 points on the SAT examination while the requirement into the College of …

Beliefs Of Science Teachers Toward The Teaching Of Science/Technological/Social Issues: Are We Addressing National Standards?, Jon E. Pedersen, Samuel Totten

Department of Teaching, Learning, and Teacher Education: Faculty Publications

As science educators, we must view the changing nature of society brought on by technology and the global nature of society as an impetus to reexamine the nature of science instruction. We have been bestowed with the responsibility to educate students on a variety of topics that less than two decades ago did not exist. Many of these social issues are controversial in nature and are directly linked to the local, regional, national, and global communities in which we exist. However, including these social issues in the extant curriculum of science has, at best, been limited. This is true even …

G79-445 Soybean Variety Selection, Leroy V. Svec

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide has information on soybean characteristics that should be considered before selecting a variety to plant.

Soybean characteristics that need to be considered in making the selection of a variety to plant include maturity, yield potential, plant type, height, seed size, emergence score, lodging, shattering, and disease and insect resistance. Many years are required to develop a new variety from the time an initial cross of soybeans is made until the time seed is available on a widespread basis. The advance of a potential variety through the early generations may be accomplished with only a few seeds of the …
