ONLINE ASSESSMENT: THE VALUE OF A FRIEND'S ASSISTANCE AgEcon
Gustafson, Cole R..
The availability of online computerized assessments is increasing, especially for economics principles courses. A severe limitation of online assessments is the possibility of cheating. Scant information is available on student preferences, behavior, and learning that is accomplished when online assessments are completed either independently or in team settings. This study investigates the performance of students in a macro-economics principles course that recently adopted online assessment with an "open book, open friend" policy. Several strategies were developed that encouraged students to learn the material independently. Data were collected throughout the semester to quantify the number of students who actually did have a friend assist them...

Learning from Assessment: Effect of Changes in an Online Course on Students' Perceptions and Performance AgEcon
Wachenheim, Cheryl J..
Student satisfaction with, and performance in, a first-offer online agrisales course was compared with that of students enrolled in a simultaneously-taught classroom course. Online and classroom students were equally satisfied with the course and the instructor using most measures, and student overall performance did not differ. However, online students tended to do better on exams while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Changes were made in the online course to improve student understanding of and ability to apply course concepts. Specifically, online student exams were no longer open-note / open-book and were proctored. On-campus online students also participated in their final sales...

HOW AN ONLINE COURSE COMPARES AgEcon
Wachenheim, Cheryl J..
Student satisfaction with and performance in an online agrisales course is compared with that of students enrolled in a simultaneously-taught classroom course. Assessment tools are developed for both sections. Online and classroom students were equally satisfied with the course and the instructor using most measures, but had different motives for course enrollment. Overall student performance did not differ. However, online students tended to do better on exams and homework assignments while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Results suggest instructors be well-prepared to handle unique learner situations prior to marketing an online course and work to ensure students are motivated to...

A Bibliography of Australian Farm Management Research and Publication AgEcon
Cooper, Ian M..
One of the outcomes of the merger of the Farm Management Society of Central South Australia and AARES was a project to record the history of the Australian Farm Management Society. As part of this project it was decided to develop a bibliography of Australian Farm Management Research and Publication. It has been produced as a web site to facilitate further development. One of the problems is what to include or exclude from the bibliography. This hinges on one's definition of "Farm Management". The approach taken will be explored and progress to date reported.

Identification key for the genera of Syrphidae (Diptera) from the Brazilian Amazon and new taxon records Acta Amazonica
MIRANDA,Gil Felipe Gonçalves.
ABSTRACT Identification keys are essential to properly recognize taxa, and a photographic key not only addresses that issue but can also attract the interest of the general public if designed correctly. Syrphidae is one of the largest families of Diptera, and the Brazilian Amazon holds more taxon records from this family than currently reported. The aim of the current study was to provide an updated photographic identification key, of easy use and access, to the genera of Syrphidae (Diptera) from the Brazilian Amazon region, and identify previously unrecorded taxa. Through a literature review and study of collection material from several institutions, I found 36 new taxon records for the Brazilian Amazon (15 are first records for Brazil) and provided a...

Using online image processing technique for measurement the browning in banana during drying (a new and automatic method) CIGR Journal
Ebrahimi, Mohammad Ali; Mohtasebi, Seyyed Saeed; Rafiee, Shahin; Hosseinpour, S..
Determination and controlling of quality parameters can be useful for ordering and marketing of fruits.  Color is the first and the most important parameter in the visual appearance of fruits, specifically in banana.  The aim of this study is to use image-processing technique (online operation) to measure and analyze the color change of banana slices during thin layer drying.  Using online-image-processing technique resulted in designing a machine vision system to control the color change of products automatically.  The results show a linear relation with high correlation coefficient for L*, a* and b* (0.967, 0.962 and 0.991 respectively) between the data of the image-processing technique and the hold-hand colorimeter.  In this study, parameters of chroma,...
