Application Lesson 3: Ecology-Soils and Salts
Application lessons or case-study based teaching is expected to enhance student’s learning by providing opportunities to apply principles or concepts of soil science. Six sets of web-based principle lessons, along with three web-based applications lessons, were developed for use by undergraduate earth science courses. The web-based application lessons included case studies that integrated agroecosystems, natural systems, and environmental science. Lessons were introduced in freshman and sophomore level soil science courses at the University of Nebraska-Lincoln, Colorado State University, and Oregon State University, in the Fall of 2006. An online based pre-test was administered prior to introducing the lessons in the classroom. An online post-test was administered after lesson use by students. A survey was also completed by students within few days days of lesson use. Student test performance improved by 10 to 69%. Survey indicated that students at all three institutions thought the lessons were useful and helped their learning. Lessons were found to be useful to all students and with good implementation strategy, they would be valuable resources to learners in a variety of contexts.

SUMMARY & FUTURE ACTIVITIES
promise. Gains in posttest score through both informal (Fall 2005, Spring 2006) and
formal (Fall 2006) assessments have been statistically significant and positive.
objectives of e-principles lessons and to allow lessons use in a variety of appropriate
such as interactivity, and quizzes at the end of each e-application lesson.
