KING  \nLockheed Martin Corporation Houston, Texas  \nAND  \nCARLOS H. HIDROVO Northeastern University Boston, Massachusetts  \nABSTRACT  \nLaboratory-based instruction is a powerful educational tool that engages students in Science, Technology, Engineering and Mathematics (STEM) disciplines beyond textbook theory. This is true in mechanical engineering education and is often used to provide collegiate-level students a hands-on alternative to course theory. Module-based laboratory instruction allows students to investigate fundamental concepts interactively and often affords new critical thinking skills and technical aptitude.  \nThe authors have developed a novel mass conservation laboratory module for use in undergraduate fluid mechanics education via module-based instruction. The module investigates mass conservation fundamentals in a simple microfluidic T-junction device. The experiment is a novel application of microfluidics-based instruction, is highly repeatable, and can be conducted at relatively low cost. The module exposes students to the rapidly developing field of microfluidics and allows them to gain familiarity with fluorescence-based optical diagnostics and simple signal processing.  \nIn addition, this study quantifies the module’s educational impact on thirty-six mechanical engineering undergraduates. A baseline study was conducted by utilizing knowledge assessments before and after the experimental module. The results of the study are statistically significant and suggest the module’s efficacy for teaching mass conservation fundamentals in an undergraduate curriculum.  \nKey Words: Laboratory, fluid mechanics, mass conservation  \nSUMMER 2015 1  \nADVANCES IN ENGINEERING EDUCATION  \nDevelopment And Evaluation of a Mass Conservation Laboratory Module in a Microfluidics Environment  \nINTRODUCTION  \nLaboratory-based learning is hugely important for effective education in Science, Technology, Engineering and Mathematics (STEM) disciplines (Elliott, Stewart, and Lagowski 2008; Jewell 2008; Fintschenko 2011) . This is especially true for engineering studies, and is argued that effective engineering education programs must feature some manner of hands-on laboratory-based education (Krivickas 2007) . The gravity and importance of lab-based work stems from the Accreditation Board of Engineering and Technology (ABET’s) selection of thirteen lab curriculum objectives meant to guide the engineering educator (Rosa 2005) . These objectives seek to develop students in many areas, including design and testing, instrumentation, experimentation, data analysis and modeling, and communication and teamwork skills. These skills afford the engineering student an educated advantage in the professional or academic setting, as they enable students to effectively confront“real world” engineering problems (Fintschenko 2011) .  \nLaboratory-based education is often accomplished through the use of small teaching lessons or modules, as compared to the continuous style of lecture-based learning. Instruction modules are becoming increasingly amenable to the learning style of today’s Millennial students, who tend to be sheltered, confident, team-oriented and high achieving (Howe and Strauss 2000) . As such, students can benefit from division of the curriculum into more manageable, interactive pieces (Wilson and Gerber 2008) which provide a more experiential, small group sized, action and reflection learning experience amenable to these personality traits. The primary benefit of utilizing module-based learning in a laboratory setting stems from its amenability to the “active learning” methodology. Felder and colleagues have found active learning allows students the opportunity to see the application of m","cbCaij8Qx3nmSrSb","https://ap.wps.com/l/cbCaij8Qx3nmSrSb","pdf",1936238,21,"English","# INTRODUCTION\n# BACKGROUND: MASS CONSERVATION","[{\"question\":\"What teaching approach does the paper emphasize for STEM education?\",\"answer\":\"The paper emphasizes laboratory-based, module-based instruction that enables interactive investigation and critical thinking beyond textbook theory.\"},{\"question\":\"What device and concept does the developed laboratory module study?\",\"answer\":\"The module investigates mass conservation fundamentals using a simple microfluidic T-junction device.\"},{\"question\":\"How is the educational impact of the module evaluated?\",\"answer\":\"The study quantifies impact on thirty-six mechanical engineering undergraduates using knowledge assessments conducted before and after the experimental module.\"}]","Development And Evaluation of a Mass Conservation Laboratory Module in a Microfluidics Environment | PDF",1792065679,53]
