Sheila Tobias, a visiting lecturer from University of Arizona at Tucson, will discuss topics centered around education at 4 p.m. today in the Holmes Student Center’s Clara Spelling Skyroom.

Tobias’ lecture is based on a four-year research project in which she asked faculty in fields other than science and math to sit in for students whom she felt were younger versions of themselves. The adult students were asked what makes science and math difficult for some.

Her lecture is part of NIU’s Social Science Research Institute’s distinguished lectures series.

ARTSTREK 90 held

NIU will hold its annual art careers conference, ARTSTREK 90, today from 9 a.m. to noon in the Visual Arts Building.
