However, the amount that college textbooks are or have been read is not well studied.Some survey and reading quiz data provide a depressing snapshot [1-6]. A 2016 survey of over280,000 college and university students found

Having originated in the discipline ofchemical engineering, this work will initially focus on that discipline before expanding to others.Over the course of this project, we will: 1) Develop a framework for categorizing representations (Phase I) 2) Adopt this framework into a user-friendly web-based electronic tool (the “app”) that will allow instructors to categorize the representations used in their course, track these representations over time, and see summaries of their representation biases (Phase II) 3) Test the “app” for usability, validity, and

, Chemical Engineering departments in the United States have been underintense enrollment pressure with over half of reporting departments responding thatundergraduate enrollment has doubled (1). Enrollment increases are often felt most keenly inlaboratory sections, where safety considerations and the availability of equipment limits thenumber of students who may participate in experiments at any one time. One possible responseto these constraints is to take some experiments that were previously performed by students andinstead present them as in-class demonstrations.Laboratories have a range of educational outcomes associated with them, including developinginterest, promoting problem-solving and trouble-shooting, enabling verification of

The video clearly shows the initial diffusive growthof the boundary layer and the subsequent onset of buoyant convection. Then when flow isinitiated, a thinning of the boundary layer on the upstream side of the cylinder is clearly visible.After showing video clips in two sections of an Introduction to Transport Phenomena course,student feedback was very positive; they found it interesting and helpful. We believe this visualrepresentation aids in learning and can actively engage students in the learning process. 1. IntroductionConcepts related to thermal boundary

oflearning by using visuals to teach concepts. However, by the time students reach middle school,these visuals are minimized or altogether discarded in favor of a canon that sublimates printliteracy to a grand, almost mythological status. In this context, language is objectified—devoidof perception or imagery and stripped down to an entity that can assist the human brain inmemorization and reasoning yet lacks visual data to fully aid the brain in observation,comprehension, and interpretation. According to Harvey J. Graff [1], educators perpetuate the misconception that, as otherforms of visual media—Facebook, Youtube, Instagram, film, TV—increase in presence,illiteracy also increases. College instructors lament students’ underdeveloped

Additionally, very littleinformation is available to answer a fundamental question about a textbook’s utility or necessity,namely how many students read their textbooks for engineering courses or any college course?Over more than four decades research shows a majority of students ignore textbook reading [1-6].For example, one study used pop quizzes to measure reading compliance and observed decreasefrom 80% in the early 1980s to about 20% between 1993 and 1997, which precedes the availabilityof handheld electronic devices [5].

First Year Students to Chemical EngineeringIntroductionEvery few years, Lafayette College updates the introductory engineering course (ES 101),based on changes in the incoming student population. Currently about 200 students enteras engineering majors. Twelve sections of ES 101 are offered so enrollment can becapped at 20 students. Each engineering major (chemical, civil, mechanical andelectrical) offers three sections. Four sections are held at the same time – one from eachdepartment. Students are enrolled in a particular section for the first seven weeks of thesemester (“Module 1”) and change to a different section (“Module 2”) for the remainingweeks. This allows each student to experience two types of engineering. It ischallenging for the

In particular, the use of open-endedlaboratory activities, as opposed to narrowly defined “recipe”-style activities, seems to beparticularly critical for learning and thinking skill development, as shown by several studies inchemical engineering unit operations courses. One previous study suggests that the use of “ill-posed problems” in unit operations can improve teamwork, critical thinking, and problem-solving, and that active engagement of the students in the problem-solving process can improveretention, decision-making, and self-directed learning

to improve understanding use of these tools.IntroductionOne of the most important things we do in educating engineers is to transfer knowledge offundamental physical principles. In the process of educating, we must then break downmisconceptions. These misconceptions can be difficult to change, requiring overwhelmingevidence or a “crisis” to change from the normal beliefs [1]. In the experiment described below,students use a common water aspirator to drop the pressure of a volatile liquid in a flask. Use ofa relatively large volume that students can touch gives them the experience of using multiplesenses to help bring them to the point of “crisis” in their own theories of what is required tomake a substance boil.While teaching Thermodynamics
