    This paper is a literature review of research related to the differences between developing an online class and a face-to-face class. Differences include how the course material is presented, how to engage the learners, and how students are learning in an online environment. Research is presented from various sources regarding considerations for online instruction and includes statistics on online student learners. The literature states that the instructor assumes a different role as a facilitator for online collaboration in a learning environment. Instructors need to consider the differences presented by distance education when creating online instruction. The advantages and disadvantages of online classes are explored for both the learner and the instructor. Discussed are current online concerns of accreditation, intellectual property rights, and student cheating. As online classes become more widespread throughout education, community colleges need to offer quality online instruction to remain competitive

    Effect of a Leading-edge Flap upon the Lift, Drag, and Pitching Moment of an Airplane Employing a Thin, Unswept Wing

    The effects of deflecting full-span, constant-chord, leading-edge flaps, having either round or sharp leading edges, upon the lift, drag,. and pitching moment characteristics of a model of an interceptor-type aircraft have been determined experimentally at subsonic and supersonic speeds. Results indicate that the variations of lift with angle of attack and of pitching moment with lift were unaffected by either the shape of the flap leading edge or flap deflection. Deflection of the flaps having either a round or sharp leading edge increased the drag at zero lift at both subsonic and supersonic speeds. In spite of the increase in the drag at zero lift, however, deflection of the flaps increased the maximum lift-drag ratio at subsonic speeds and had no deleterious effect at supersonic speeds
