Williams, Ph.D. Associate Professor All professors at: Northern Arizona University The W. A. Franke College of Business PO Box 15066 Flagstaff, AZ 86011.5066   The Effect of Learning Styles on Course Performance: A Quantile Regression Analysis Introduction Students have different learning styles. “They preferentially focus on different types of information, tend to operate on perceived information in different ways, and achieve understanding at different rates” (Felder, 1993, p. 286). In this study, we investigated the relationship between student performance and learning styles for students enrolled in a basic business statistics course. This course was recently redesigned in order to facilitate learning for students of all learning styles. A learner-centered approach that incorporated multiple teaching styles such as student responsibility via mastery and co-operative learning that used teams in several course components was adopted. In addition, the focus of the redesigned course was on interpretation and implications of statistical results instead of the mechanics of computation (Lockwood, Ng, & Pinto, 2007). To assess our success in designing a course that facilitates learning for all learning styles, we evaluated the impact of students’ learning style...

Why (a) do you suppose Union Planters purchases investments, rather than simply making loans? Why does it purchase investments that vary in nature both in terms of their maturities and in type (debt versus stock)? 1. They may have excess funds that they havent loaned out yet and instead of having the money just sit there the bank manager may decide that it could earn more revenue by choosing to invest. 2. Depending on the situation the bank manager may also feel that they can make more money by investing the excess funds rather than lending the money out. For example right now interest rates are at an all-time low and they may feel like the return on the interest is not enough compared to investing. 3. The bank manager may feel that these investments will mature and be worth more in the future so they may choose to hold long term to create more revenue. (b) How must Union Planters account for its investments in each of the two categories? 1. Trading securities Balance sheet at fair market value a. Gain/Loss reported as part of income 2. Available-for-Sale Balance sheet at fair market value a. Gain/Loss Comprehensive income/ separate from Stockholders equity until realized 3.

Playing along with a quiz show; requesting a product sample during an advert; taking a breakfast news feature with you on your morning commute so you can finish watching; all could be routine. Despite the enablers and technology being in place this seismic shift in the viewing experience stubbornly refuses to mainstream. Why? A number of obstacles stand in the way: • Consumers brought up on a passive, linear TV experience show ingrained lean-back behaviour • The broadcast industry can be risk averse and ambivalent about commissioning multiplatform formats • The sheer range of operating systems across devices...
