Mr. Lotanna Ezeonu is a materials science and engineering PhD candidate at the verge of completing his program. He joined Stevens Institute of Technology for his graduate studies with a provost doctoral fellowship award in 2017 after earning a B.Eng in metallurgical and materials engineering from the University of Nigeria, Nsukka.
His doctoral research focus is on the synthesis, characterization and testing of catalytic metal nanoparticles for biomass upgrading and propane dehydrogenation technologies. For his masters research, he developed a novel template-supported gold nano-test tubes for surface enhanced Raman sensing application.
In addition to his research responsibilities, he works as co-instructor for a core sophomore level engineering course entitled "materials processing". Mr. Ezeonu conducts various training and workshop opportunities to provide students with the tools they need for their final project using a knowledge building model. He also oversee 6 undergraduate facilitators who assist with various aspects of the course.
This work gives details and results of an evidence-based practice adopted for teaching a large introductory engineering course titled: “Introduction to Materials Science and Engineering” (a 3-credit hour course) required for all engineering students in their third year. Historically, this core engineering course has been taught in a traditional teacher-centered way. Over the past several years, we significantly revised course content, design and delivery so students could experience a knowledge-building culture. The goal was to facilitate their development as deep and life-long learners. After coverage of basic materials concepts in the first half of the semester, students are challenged to create and evaluate an authentic idea that would help reduce microplastic pollution in the oceans. A series of learning activities was developed and used to guide students to identify a plastic product of their interest and assess quantitively and critically how the product could be redesigned and/or made with alternative materials. These learning activities include: (1) workshops to guide students through divergent and convergent thinking and equip them with necessary knowledge needed to embark on the project, (2) report development with feedback from undergraduate teaching assistants, and (3) self-reflection to prompt students to think about what and how they learned, and their perceptions of the impact of the knowledge building approach on their learning. Due to large enrollments (over 250 students per semester), Canvas-based digital tools were extensively used to administer these learning activities along with significant contributions from undergraduate teaching assistants. Despite the limitations associated with large enrollments, our experience suggests that the knowledge creation approach can be effective in engaging engineering students in problem-solving, knowledge synthesis, written discourse and reflection that enables deep learning.
