Developing Inquiry-Based Laboratory Exercises For A Mechanical Engineering Curriculum, Sriram Sundararajan, Leann E. Faidley, Terrence R. Meyer
Developing Inquiry-Based Laboratory Exercises For A Mechanical Engineering Curriculum, Sriram Sundararajan, Leann E. Faidley, Terrence R. Meyer

This paper describes the development of two inquiry-based experiments in a mechanical engineering curriculum at a land grant research-intensive university, aimed at providing students with the opportunity to design and perform experiments. One experiment in engineering measurements (system behavior) and one experiment in fluid dynamics were developed. In each case, students working on teams were posed with a scenario and question to answer. For example, in the system dynamics experiment, students were asked to verify that a thermal system and electrical system were mechanically equivalent systems. In the fluid dynamics experiment, students were asked to investigate drag coefficients for flow …

This study examines the design and evaluation strategies for a year-long teacher learning and development experience, including their effectiveness, efficiency and recommendations for strategic redesign. Design characteristics include programmatic features and outcomes: cognitive, affective and motivational processes; interpersonal and social development; and performance activities. Program participants were secondary math and science teachers, partnered with engineering faculty mentors, in a research university-based education and support program. Data from multiple sources demonstrated strengths and weaknesses in design of the program's learning environment, including: face-to-face and via digital tools; on-site and distance community interactions; and strategic evaluation tools and systems. Implications are considered …
Educational Apps: Using Mobile Applications To Enhance Student Learning Of Statistical Concepts, Chen Ling, Drew Harnish, Randa Shehab
Educational Apps: Using Mobile Applications To Enhance Student Learning Of Statistical Concepts, Chen Ling, Drew Harnish, Randa Shehab
Dr. Chen Ling
This research sought to understand whether the use of mobile applications (e.g., iPhone apps) had an impact on students’ learning of new statistical concepts. A control group (n = 12) was compared against a group that used a statistical mobile app (n = 13) during a simulated statistics lecture on the topic of normal distribution. Students received a classroom lecture followed by a period of either pencil-and-paper only or technology-assisted examples. They then took a quiz on the material. The overall quiz results showed that the app group outperformed the control group. When learning through examples with the mobile app, …

The present study follows a cohort of 17 K-12 teachers through a six-week resident learning experience in science and engineering, and on into the planning and implementation of applications for their classrooms. This Research Experiences for Teachers (RET) program was examined using the strategic approach of design-based research, with its fluid, adaptive management of the complexity of authentic learning "in situ" and its attentive documentation of expected and unexpected events, in process and products, to capture the richness of teachers' and mentors' experiences. Research on effective teacher professional development, adult learning, situated cognition, and learning transfer were utilized to inform …

This study examines the inputs (processes and strategies) and outputs (perceptions, skill development, classroom transfer, disciplinary integration, social networking, and community development) of a yearlong, interdisciplinary teacher learning and development experience. Eleven secondary math and science teachers partnered with an interdisciplinary team of university engineering mentors in a yearlong engineering education and project implementation program. It consisted of a 6-week on-site resident professional development and collaboration experience, with an ongoing support and follow-up including digital systems. Mixed-method, multisource data indicate that teachers engaged with motivations combining personal, intrinsic interest and classroom integration goals. They formed and sustained an active community …

This paper presents the research on optimization of plunge centerless grinding process when grind 20X – carbon infiltration steel (ГOCT standard - Russia) to achieve minimum of roundness error value. The input parameters are center height angle of the workpiece ( ), longitudinal grinding wheel dressing feed-rate ( Ssd ), plunge feed-rate ( k S ) and control wheel velocity ( dd v ). Using the result of 29 runs in Central Composite Design matrix to given the second order roundness error model. Genetic algorithm and Response surface method were used to focus on determination of optimum centerless grinding …
