Title of Presentation: Preparing Students for the Future of Science in GN 301: Genetics in Human Affairs


As we enter the new millenium, some of the most fascinating and controversial issues revolve around the field of genetics. Many current advances in medicine rely on discoveries in genetics. Genetics 301: Genetics in Human Affairs focuses on the basics of genetics and how they are applied in today's society. Students in this course are not necessarily science majors, so they learn a great deal about the principles of genetics, including how genetics affects our species and our world. As the coordinator of the teaching assistants in this large enrollment course, I was responsible for all assignment grading and recording. To enhance the teaching assistants in this large enrollment course, I was responsible for all assignment grading and recording. To enhance student learning, I led review sessions before tests and also provided one-on-one tutoring as needed. These duties are fundamental to being an effective teaching assistant in GN 301.

It is imperative that students realize that genetics is a rapdily evolving field. Therefore, they were required to submit summary reports of current articles in genetics. I posted their articles on the bulletin board and walls of the classroom. In order to assure that students were aware of new developments, I created two newsletters based on students' summary reports. I made overhead transparencies clearly articulating key points of the articles, and drafted questions to provoke class discussion. These discussions mainly focused on ethical issues stemming from the articles. My goal was for students to provoke class discussion. These discussions mainly focused on ethical issues stemming from the articles. My goal was for students to become more aware of and interested in, and as much as possible active participants in, genetics and society.

Through my position as the teaching assistants' coordinator in Genetics 301, I am confident that I contributed to students realizing and understanding the significance of genetics in society today and the possibilities for genetics in the future.

Title of Presentation: Group Dynamics of ALS 398H Teaching Experience


To study the group dynamics of the ALS 398H class, a correlation between predicted group efficiency and actual efficiency was made. Nine students were given the task to investigate a current topic and prepare an oral and written report. The students decided that the task would be more easily accomplished if they broke into smaller groups and tackled subdivisions of the main issue. Before breaking into groups a the "DISC" test was taken by each student to determine their work style. Among the three small groups, one "D" was assigned and then the other members of the group were assigned arbitrarily. Based on the working styles of members involved in each group, a prediction of the samll group efficiency was made. Actual group efficiency was determined by the group members throughout the progression of the class.

My personal experience gained from this is to see how to work more efficiently with and around others. By determining my own work style I could see under what conditions I perform best in, but more importantly, how others percieve my actions. Also by recognizing others' work styles, I can cater to their working needs to get tasks accomplished more efficiently.

Title of Presentation: Undergraduate Teaching Assistant: ANS 220 - Reproduction and Lactation of Domestic Animals


ANS 220 is a required course for most Animal Science students. However, it is a valuable course for anyone taking it. It is a course that facilitates learning and inspires thought. The basic skills and knowledge learned in this course and lab will be an asset to anyone taking it.

Being a teaching assistant for this course has been an extremely worthwhile experience. As an undergraduate teaching assistant, I attended weekly meetings with Dr. Whisnant. Also, I varyingly met with students needing tutoring help, attended labs, graded papers, and aided in demonstrations and lectures.

In a mid-semester evaluation, most students seemed satisfied with the labs and lectures. Students gave honest feedback on how to improve the lab and lecture area. However, the most interesting part of the survey is that the hands-on experience is something every student commented as being valuable and what he or she liked best about the lab. Over 95% of the class responded to the survey.

In being a teaching assistant, I have improved my speaking, writing, and overall communication skills. Also, I have a much better understanding and appreciation of what is required of a professor in order to be successful at teaching a class. The experience, overall, has taught me leadership, patience, and discipline that will be beneficial to any future experience - academically or professionally.

Title of Presentation: Trends in Pursuits of Undergraduates in the College of Agriculture and Life Sciences Honors Program


The students of the College of Agriculture and Life Sciences Honor Program represent the motivated and outstanding achievers of the curricula within the college. Eligibility for enrollment into the College of Agriculture and Life Science Honors Program is based on a minimum Grade Point Average of 3.35 overall, and invitations are extended for eligible students generally during their sophomore or junior years. Those enrolled in the Honors Program have already excelled in their undergraduate experiences, and the vast majority of these students are seeking to further their education after gradation from North Carolina State University. After surveying the students of the ALS 398 Honors Course, it was determined that approximately 38% of the students will pursue Medical School, 22% Veterinary School, 3% Dental School, 1% Physical Therapy, 1% Pharmacy School, and 29% of the students will pursue Graduate School. The remaining students surveyed are either undecided (3%) or will seek to find a job immediately upon graduation from North Carolina State University (3%). This study shows that ambitious students who wish to enhance their educational experience seize the opportunity to participate in the College of Agriculture and Life Sciences Honors Program. By enrolling, the students not only gain personal and small group interaction with faculty members (whom they otherwise may never have met), but the Honors Program also gives the students research and experience for a competitive dimension to their academic transcripts.

Title of Presentation: Honors/Scholars Programs in the Southeast


The Morril Land Grant Act of 1862 authorized the formation of Land Grant Universities in the United States. North Carolina State University (NCSU) was founded in 1886, and has developed into one of the premier universities among its fellow Land Grant Institutions. Many Land Grant institutions in the southeast sponsor an Honors/Scholars program at the university level, but only three, including NCSU, have an Honors/Scholars program at both the university and the individual college level. These programs are designed to enhance a student's educational experience and to better prepare those students for opportunities in the professional, industrial or academic career fields.

The present project surveyed all of the Land Grant universities in the southeast with respect to their specific Honors/Scholars Programs. In general, the colleges of Agriculture were initially contacted. The survey questions ranged from how many credit hours are required to fulfill the requirements of each particular program, to what is the gender and ethnic profiles of those students in the programs. The survey was completed by each school and was instrumental in helping gain a better understanding of the specific dynamic of each individual Honors/Scholars program. Typically the Assistant Dean of Academic Affairs for the specific college completed the survey and returned via email. Some of the schools were able to answer all the questions completely; while other schools only partially completed the survey. The responses gave a wealth of information. The GPA requirements for the programs range >from 3.25 to 3.75. Entrance into these programs ranged from a freshman year up to the student's sophomore year. Hopefully, the results of this project will help NCSU's leaders better understand the direction it desires to take with respect to the honors and scholars program at both the university and college level.

Title of Presentation: Ans 220 Reproduction and Lactation of Domestic Animals: Undergraduate Teaching Assistant


I fulfilled my ANS 499H requirement by being a teaching assistant for ANS 220. The decision to be a teaching assistant for this class stemmed from the fact that I really enjoyed the subject material and still had a good grasp on a lot of the concepts and ideas presented in class. I was involved moe with the lab that goes along with the class instead of the lecture itself.

Each lab brought new activities to be done. On most weeks I assisted in making out the weekly quizzes as well as the administering and grading the quizzes. My assistance was also given at the review sessions for the lab practical. Also, I tried to be around before lab so that I was able to answer any questions that the students might have. Along with this I also attended weekly meetings with the other teaching assistants to go over the agenda for the next weeks lab. Lastly I had to be sure that I knew the subject material that was going to be covered in the labs so that I was accurately able to answer questions.

Through this experience I have brushed up and gained new skills. I have thouroughly reviewed all the course material and will leave this teaching experience knowing even more about reprocuction and lactation. Also, I have gained the experience of working as a team with the other teaching assistants. Along with this I have increased my people skills. I now feel more comfortable in front of large groups.

Title of Presentation: Learning in the Animal Diversity Laboratory: The Effects of Different Teaching Styles on Student Performance on Practicals


A sample of 130 college students from six sections of the ZO 150L: Animal Diversity Laboratory were randomly subjected to three treatments of laboratory teaching styles. The treatments included one control and two experimental teaching styles. With the two experimental treatments, an undergraduate teaching assistant (in addition to the graduate teaching assistant) was present during the laboratory sessions. The experimental treatments were termed 'active' teaching and 'passive' teaching. With the control treatment, no additional teaching assistant was present. It was hypothesized that students exposed to the active teaching style would perform best on practicals, followed by those who were exposed to the passive teaching style, and those students exposed to the control treatment would do worst. After the practicals were taken and graded, data were taken from the practicals, and statistical analyses were performed on the data. In analyzing the data, it was found that there was not enough significance (p < .05) to test the hypothesis.

Title of Presentation: Preparation of a CD with Interactive Movies of Cat Anatomy


Computer software is the new rapidly growing frontier in education. In biology classrooms, laboratory simulations and interactive video CDs are proving to be very beneficial for both the teachers and the students. They have been shown to improve learning of concepts, increase teacher-student interactions, help the students work at their own pace and encourage the students to become more involved in their education, as well as to reduce safety hazards and unnecessary animal experimentation.

Our project was to prepare a compact disc with real digital images of the cat anatomy. My responsibility in this project was the cardiovascular system. I performed dissections of preserved cats and helped take the digital pictures using a Nikon digital camera. I then helped edit the digital pictures and added labels to the pictures using Adobe PhotoShop. I also wrote all the text explanations for the cardiovascular pictures. Then using Electrifier Pro, we turned the labeled pictures into the final interactive movies. In the final project, all the biological systems of the cat will be included on the CD: The skeletal, muscular, cardiovascular, urogenital and other internal organs, and the nervous system. Each movie includes the original picture with pop-up labels, auditory tracts with moving arrows explaining the picture, links to textual explanations, links to related histology pictures and sometimes links to alternate views of the anatomy shown.

This CD will be useful particularly for Dr. Betty Black's Developmental Anatomy and Histology of Vertebrates classes at NC State (ZO 370, 371, 375, 376). This CD will also be available through Carolina Biological Supply Company for other high school and college level teachers and students.

Title of Presentation: Leaders Teaching Leaders: The Challengesof the ALS 398H Teaching Experience


The Agriculture and Life Sciences Honors Program is designed to provide a challenging and self-motivated working and learning environment for outstanding students. The students participating in the program chose a topic of interest to study for the semmester and presented their research in an oral, visual, and creative format to a group of their peers. The teaching assistant in the Biology of Stress section has many roles. While observing the dynamics of the group of nine students it is my responsibility to encourage the group to challenge and support each other in research. Each student has chosen a topic to present to the group in whatever format he or she chooses. During this presentation the group is open to discussion of the topic and is encouraged to ask questions. While individually learning to convey information in a clear and complete manner, the students practice critical thinking and leadership. As a teaching assistant I facilitate the conversations by maintaining the focus of the session and encouraging the more passive students to express their views. The ALS 398H teaching experience is challenging and stimulating. I have been able to gain leadership experience while continuing to learn from each student. Through working with each student, I have learned to interact with people of different personalities on an intelligent and stimulating level. The experience gained by everyone in the class will be highly valuable in their success in future academic and professional endeavors.

Title of Presentation: The Design and Publication of the Powdery Mildew Homepage for the North Carolina State University Department of Plant Pathology Internet Site


Powdery mildew is a disease of interest to growers of fruits, vegetables, grains and ornamental landscape plants. The disease is caused by fungi in the order Erysiphales and have the potential to cause great economic damage to certain crops. The disease is of particular importance to North Carolina due to the growing market in the area of nursery and greenhouse grown ornamental landscape plants.

The North Carolina State University Department of Plant Pathology Homepage is a resource used by students, faculty, industry professionals and the general public to gain valuble information on a wide variety of plant diseases. The newly designed powdery mildew homepage aids in supporting the extension work conducted by the Plant Pathology Department as well as serve as a teaching site for students in botany, horticulture, and plant and forest pathology.

The powdery mildew homepage includes detailed information on the disease's causitive pathogens, disease cycle, life cycle, morphological appearances as well as an identification key to the common genera of Erysiphales found in North America. The site's written content is supported by state-of-the-art image capture technology in the form of microscopic images of Erysiphales from the Plant Pathology's Herbarium collection.

In a continued effort to make plant disease information available through the World Wide Web, the Plant Pathology homepage will now include a detailed site on powdery mildew to inform and educate members of the University and professional community as well as the general public.

Title of Presentation: Development and evaluation of student use of online quizzes for ANS 230 - Nutrition of Domestic Animals


ANS 230, Nutrition of Domestic Animals, is an introductory course covering both principles of nutrition and applied feeding of domestic animals. By taking this course a student gains a basic knowledge of nutrition, digestion, and absorption in domestic animals. The goals of this project were to develop an interactive World Wide Web page containing self-grading quizzes for students enrolled in ANS 230 to use as a study aid in exam preparation and to evaluate use of the quizzes by those students. This web site contained a series of four quizzes that corresponded with the course material covered on the four lecture exams. The results of the quizzes were stored online to determine how many students were using this resource and the scores received on the quizzes. A total of 63 students utilized the quizzes, which was 77% of the enrolled ANS 230 students. The average grades on the quizzes, excluding scores of zero, were as follows: quiz 1- 81.4 %, quiz 2 - 81.3%, quiz 3 - 78.4%, and quiz 4 - 90.2%. A questionnaire was given to students during the final week of the course. From this questionnaire it was determined that all of the students who used the quizzes found them helpful in reviewing key concepts covered in lecture material. Characteristics of the quizzes that students viewed favorably were the easy online access and the immediate graded feedback. The students who did not use the quizzes stated that the lecture notes and text adequately prepared them for the exams or they did not have enough time available in their schedule to take the quizzes. Finally, the survey revealed aspects of the quizzes that needed improvement. Students expressed a need for more questions on the quizzes, different types of questions (not solely multiple choice), and increased quiz difficulty to more closely match instructor's exam questions.

Title of Presentation: Survey of Interests in Animal Science Classes


The purpose of this project was to see if the Animal Science classes and background of students were related to the student interests and towards their future career. A survey was prepared that had a range of questions covering many aspects of students' backgrounds, experience and interests. This survey was administered Fall semester 1999 to three core curriculum classes in the Animal Science Department: ANS 150, ANS 205, and ANS 220. ANS 150 represented freshmen, ANS 205 represented sophomores, and ANS 220 was a mixture of non-Freshmen students. Over 70% of students in all three classes were majoring in Animal Science with a science concentration. Students in ANS 205 and 220 planned to go to professional school (approx. 12% more) rather than graduate school. In contrast, 13% more of freshmen preferred graduate school to professional school. Before coming to NCSU, students had about equal experience with livestock/commodity, equine, companion, and exotic. This trend changed for ANS 150 students, who clearly had more experience with livestock/commodity (only 17% before and 65% after coming to NCSU). Among all 3 classes, 82% of the students felt that the major emphasis in class is livestock/commodity. Over 60% of students interested in livestock/commodity and equine felt that these animals were well studied. Students interested in companions were halfway satisfied and over 90% of students interested in exotics felt these animals were poorly represented in class. Over 90% of students in ANS 150 and 220 felt that a land-grant university should not limit studied animals to production species, and surprisingly, 87% of ANS 205 students felt it should be limited to production species. Students feel that the experience gained in classes is very important for their future. In conclusion, students have the interests in animals that both to which their background and ANS classes have introduced.

Title of Presentation: Implementing a computer-based exercise in the Evolution, Behavior, and Ecology Laboratory


The laboratory course in Evolution, Behavior, and Ecology (ZO 260) is designed to complement the lecture section by giving students opportunities to test hypotheses about the natural world in the field. The laboratory has traditionally neglected evolution, a field that is difficult to investigate in a three- hour lab period. After serving as an assistant T.A. for the Spring 1999 semester, I proposed basing a lab on the ecological modeling program EcoBeaker for students to explore first-hand the importance of allele frequencies and natural selection in evolution. Using the "Heterozygote Advantage" scenarios, we explored the unique relationship between Malaria and Sickle-Cell Anemia. The EcoBeaker program allows us to trace the change in sickle-cell allele frequency over time under different environmental factors. Students formed and tested hypotheses for various simulations. A four-page introduction for the lab focused on developing hypotheses and using models in ecology. I developed a series of questions to guide students through various experiments using the program. Open-ended discussion questions encouraged the teams of students to develop and test original hypotheses. Using computer modeling exercises in the Evolution, Behavior, and Ecology Lab allows students to grasp abstract concepts more readily through exploring hypothetical scenerios. This learning tool, in conjunction with field exercises, provides a more enriching educational experience.

Title of Presentation: Informal Supplemental Instruction, Lab Teaching Assistant and Soil Microarthropods: A Teaching Experience in Zoology 150


My work for the ALS 498 and 499 courses was with Zoology 150: Animal Diversity taught by my faculty mentor, Dr. Samuel Mozley. After taking this course, I knew the level of difficulty students often displayed in mastering the material for the class. As part of my honors project, I researched the methods employed in Supplemental Instruction(SI) sessions used regularly here on campus for courses such as Chemistry 101. At Dr. Mozley's request, I decided to implement an informal SI program for the class. The sessions were scheduled either once or twice a week for one hour, with extra sessions before an exam. The sessions focused on discussing ways to come to the right answer rather than me directly answering questions.

The second part of my project invloved my creation of a lab exercise on Soil Microarthropods. For this, I picked through samples of soil litter and isolated species to be put on microscope slides. I then identified the species and researched their characteristics. The slides were viewed using a microscope attached to a computer and then photographed using a Nikon Alphashot camera that was attached to the microscope and computer. I then incorporated these images into a thirty minute Power Point presentation that was presented to the Zo 150 class during their lecture period.

This experience gave me the opportunity to gain laboratory experience while I was isolating the Soil Microarthropod species as well as teaching experience throughthe preparation of a Power Point lecture/lab presentation.

Title of Presentation: Black Magic for Men in White Coats: A glimpse into the world of medicinal plants


Plants and Civilizations (BO 213) provides a detailed look into the many ways plants have played a intricate roles in the development of human society. The objective of this project was to develop supplemental lecture material on the uses of plants for medicinal purposes. Although aspects of plants with medicinal qualities are briefly discussed in conjunction with cultural, socioeconomic, or religious sections of the course, this project provides a detailed focus on many plants that have had a profound effect on medicine and human civilization.

Often in our contemporary world of revolving door doctors' offices and hospitals, it is difficult to see the origins of many of our modern medical cures. Many of these medicinal plants have been utilized by people for hundreds, if not thousands of years, and have been intricately woven into their society and culture. The underlying theme of this presentation is that many compounds synthesized in plants have provided the blueprints and basis for chemists and doctors today.

Participating in the Als 498 and 499 series has provided a useful experience for both the students and myself. I have gained valuable knowledge not only in this particular topic, but also in playing an active role in others' learning. Hopefully I have been able to enhance students' learning experiences and sparked an interest in further study of medicinal plants.

Title of Presentation: Video-Taped Conferences: An Effective Communication Vehilce to Relaying Equine Management Practices to North Carolina Horse Owners


Extension Horse Husbandry (EHH) of North Carolina State University, traditionally provides the North Carolina equine industry with various learning opportunities. However, professional time and funding are two limiting factors affecting the current delivery of educational programs. The 2000 REINS (Regional Equine Information Network System) Horse Management Video Conference, designed in conjunction with EHH and funded by Cargill Nutrena, Inc., was developed to relay information in a much more efficient, cost-effective, manner. Instead of using the funding for travel and professional costs of the specialists, financial support was invested in the production and distribution of a brochure, used to promote the video conference, and videos along with hand-outs and evaluation forms. The videos, ranging in length from 38 to 92 minutes, included six topics: "Basics of Horse Ownership", "Basic Horse Health Care", "Evaluating Commercial Feeds", "Stallion, Mare, and Foal Care", "Nutrition and Health of the Senior Horse", and "Feeding the Performance Horse." Various combinations of the six topics were offered at each site to assess their impact on horse owners adopting management practices. The videos were sent to 19 sites and held from January to March ranging in length from one to six hours. REINS volunteers and Extension Agents answered questions and presented supplementary topics in addition to the videos. After the viewing dates, the videos were placed in a library and will be checked-out upon request. Results indicate the video conference was an efficient, successful method that provides horse management practices in a more timely, cost-effective manner.
