online learning: greater flexibility maypromote greater procrastination with concurrent negative consequences. Procrastinationis especially prevalent among novice online learners, specifically the male traditionalcampus-based undergraduate student. This paper investigates the relationship betweenperformance and procrastination for campus-based “traditional” students enrolled in afully online, large enrollment (300+ students a semester), general education class.Procrastination was rampant with 40% of students typically starting the weekly lesson(s)on the due date(s). Procrastinators had reduced grades (6% lower or an average “A” to“B+/A-” transition) for weekly reflection activities. Males were more susceptible tonegative consequences in

The coursescan be taken by undergraduates or masters students. The majority of students taking thecourses were seniors. An anonymous survey was given during the final exam period of the control classwith the purpose of determining student patterns in class attendance and textbookreading. The survey included four closed ended questions. Responses are shown infigures 1 and 2. Open ended questions, “When you miss class what is the primaryreason(s)?”, “Why have you taken your approach to reading textbooks for classes?”, and“What is your preferred method

At Georgia Tech and Lafayette,students were encouraged to select a local municipality, investigate the condition of a type ofinfrastructure and the municipality’s current management practices, and make recommendationsfor improving those practices, including the development of a conceptual plan of an

A Community of Learners:Building a sense of community during the first week of the course provides a critical andsolid foundation for the success of the course. A threaded discussion can be veryeffective in accomplishing this task. This course incorporated a “Tell Us About You”threaded discussion assignment to allow students interact and share personal informationthey were comfortable with such as hometown, major, work experience, background, andother information or photo(s) they would like to include.

these patterns into four dimensions, with twopossibilities in each dimension. Table 1 summarizes the four dimensions and provides someconcrete examples of how they manifest in learning preferences.Over the past several decades, many studies have shown that some MBTI types tend to strugglein or drop out of engineering programs more than others. These findings are most oftenexplained by mismatches between traditional teaching styles and the learning preferences ofmany of our students. In general, traditional engineering education is biased towards Introversion(I) over Extraversion (E), Intuition (N) over Sensing (S), Thinking (T) more than Feeling (F),and Judgment (J) over Perception (P).4,6,9 The S-N dimension is particularly influential

done using the electrical analogy.The author learned of this approach at North American Aviation in the early 60’s. This approachis useful for setting up the difference equations and boundary conditions for use in a Spreadsheet.An electrical analogy for heat transfer in a 1-D wall broken into nodes is shown in Figure 3. Inthis analogy, boundary nodes and surface nodes do not have a means for storing energy whereasinternal nodes have a mass associated with them and therefore a thermal capacitance. Thethermal capacitance represents the amount of energy per unit temperature change and is theproduct of the specific heat and mass of a node. The resistances between nodes can be analogousto convection, conduction and even radiation.In Figure 4 an
