From pup­petry to world his­tory, there’s not a sub­ject on Earth that can’t be made more inter­esting through the use of inter­ac­tive games and lessons, said Carnegie Mellon pro­fessor Don Marinelli to a standing-​​room-​​only crowd at Northeastern’s Teaching with Tech­nology Day on April 14 in the Curry Stu­dent Center.

A drama and arts man­age­ment pro­fessor, Marinelli is exec­u­tive pro­ducer of the Carnegie Mellon Enter­tain­ment Tech­nology Center (ETC), which brings together tech­nol­o­gists and fine artists to col­lab­o­rate on new media projects.

Marinelli’s lec­ture was part of the mini conference’s larger effort to show­case the ways in which North­eastern stu­dents, fac­ulty and cor­po­rate part­ners have incor­po­rated tech­nology into the class­room setting.

Pro­fes­sors from col­leges and uni­ver­si­ties throughout the region — including Har­vard Uni­ver­sity, Boston Col­lege and Sim­mons Col­lege — attended the all-​​day event.

Marinelli, 56, who vowed “never to be the type of teacher I had growing up who told me I would grow out of all the things I enjoyed — rock n’ roll, long hair and peace, love and under­standing” — landed the per­fect gig as exec­u­tive pro­ducer of Carnegie Mellon’s ETC, a joint ini­tia­tive between the Col­lege of Fine Arts and the School of Com­puter Science.

He cofounded the center with the late Randy Pausch, the pro­fessor of com­puter sci­ence of “Last Lec­ture” fame, who cre­ated “Alice,” a free, open-​​source edu­ca­tional pro­gram­ming language.

Marinelli touched on the center’s edu­ca­tional project-​​based approach toward teaching and solving real-​​life problems.

He said that graduate-​​level stu­dents helped drive more traffic to the Carnegie Library by designing a com­puter pro­gram called “My Story Maker” that allowed stu­dents to write and print out their own books at the library.

Stu­dents also col­lab­o­rated with the Pitts­burgh Children’s Museum on a project that enabled chil­dren to build down­load­able, ani­mated puppets.

Marinelli encour­ages his stu­dents to do the teaching, noting that they’re more attuned to the latest trends in video gaming and com­puting than he’ll ever be. “You teach me what’s cooking in the world of mas­sively mul­ti­player online gaming and I’ll tell you about money, life, girls and travel,” he quipped.

But he’s not all fun and games. He recently met with the U.S. Joint Chiefs of Staff to dis­cuss a videogame that the center designed to diag­nose trau­matic brain injuries suf­fered by troops in combat.
