nce_sp_final.pdf On February 22, 2010 I presented to you a Strategic Planning document for NCE. As a follow up, we created 7 subcommittees, one on each of the ”priorities” outlined in the document. I am attaching the document to this blog for easy future reference. Each of these subcommittees has about [...]

A friend of mine recently emailed me an interesting piece that I wanted to share with you. The source of this piece is unknown else I would have duly acknowledged the source. Please read and I hope you will enjoy it as much as I did. The dinner guests were [...]

Last Friday, I had a chance to visit with Lamont Thomas – he is the new principal of Science Park High School which is located about less than half mile away from our campus. The High School does not currently offer courses in Engineering and Principal Thomas told me that [...]

Assessment, both at the program level as well as at the course level, is a major component of ABET accreditation. Assessment is to be used to introduce improvements and is to be done on a continued basis. For a faculty member teaching a course, this can be done relatively easy. For [...]

Dear Faculty, Staff, Students, Alums and Friends of NCE. I would like to use this blog to communicate with you on a frequent basis. I invite you to provide me with your input to various developments happening in NCE that I report to you through these pages. Of course, a personal [...]
