Iman Osta

Dr. Iman Osta is an associate professor of mathematics and computer education. She chaired the Department of Education from October 2010 to September 2012. She also served as assistant dean of the School of Arts and Sciences from October 2014 to September 2018.

Dr. Osta was an education faculty member at the American University of Beirut from 1990 to 1999, after which she joined LAU. Throughout her career, she has taught graduate courses in mathematics education, curriculum design, research methodology, educational technology and others, as well as undergraduate courses in the fields of pre- and in-service teacher preparation for teaching mathematics at all grade levels, for teaching science at the elementary level, as well as computer education for teachers.

At the national level, Dr. Osta contributed to the development of the Lebanese curriculum for informatics and chaired the national Evaluation Committee for the math and informatics curricula. From 2007 to 2011, she led and worked on a collaborative project with Michigan State University for developing three gender-sensitive courses in Educational Technology for teachers.

Since 1990, she has conducted many workshops for teachers (problem solving, teaching of geometry, number sense and mental math, technology in teaching mathematics, meaningful learning of math, motivation in math classes, connecting math to life, representations in math teaching and learning, educational assessment, and others).

Dr. Osta has published research work on the use of computer technology in the teaching and learning of geometry, on student learning assessment and curriculum evaluation, and on the learning of algebra.

In fall 2013, she became affiliated to the University of Maryland as a Fulbright Visiting Scholar to conduct research in collaboration with the team of the Mathematics Education Center at the University.
