Web-Based Instruction Prof. James S. Aber Earth Science Department Emporia State University

Overview

Online curriculum is more flexible and can adjust to different learning styles in comparison to the "one size fits all" lecture of traditional college courses. Curriculum based on solving real-world problems--pragmatic coursework--is particularly successful in the asynchronous mode of most distance learning. Some students view online courses as a quick and easy way to a college degree. But, in fact, distance-learning students should expect to spend just as much time and effort as they would in equivalent on-campus courses. Time management is a key skill necessary to balance a career, family, and academic work for most online students.

Based on research conducted at Mesa Community College, Johnson (2002) found no significant differences in outcomes between students taking the same biology course from the same instructor in on-campus or distance-learning modes. She concluded that students in either mode can learn as much, develop their reasoning skills, and have positive attitudes toward the subject matter. However, distance-learning students need self discipline, good reasoning ability, and strong backgrounds to succeed.

With all the online choices available, how should a new student find the right program? According to U.S. News & World Report (Oct. 16, 2006), three things are most important.

1. The first thing to look for is college or professional accreditation, which assures that the institution has qualified faculty and staff, suitable curricula, and a good library. Emporia State University is fully accredited.

2. Next is the level of technical skill and equipment necessary for a given program. This generally means an up-to-date computer and good Internet connection with standard web-browser and email software. For certain courses in the earth science program, FTP and other specialty software may be required.

3. Finally students should investigate how the courses are delivered. Earth science courses are typically taught in the asynchronous mode, meaning that students work on assignments whenever they are able--day, night or weekends, and turn in their work according to a weekly schedule.

• Appropriate incentives--release time, salary, rewards, promotion and tenure.
  
• Internet/computer infrastructure--campus network, webservers, faculty computers.
  
• Campus computer support--professional and technical assistance, trouble shooting, etc.

• Cost--time, equipment and personnel require significant financial commitment.
  
• Administrative organization--college, school, department, and committee levels.
  
• Campus bureaucracy--interface between on-campus and distance-learning administration.
• Ownership of curriculum--faculty as the authors, university as the publisher.
