This paper describes our experiences in promoting a learning environment where active student involvement and interaction, as well as openness to diversity of ideas are supported through innovative uses of technology in the classroom. In the context of an undergraduate course in software engineering, for two consecutive terms we have experimented with an existing software system for Tablet PCs that supports a set of classroom interaction styles. Our goal has been to determine if the use of the technology can increase the effectiveness of pedagogical techniques that naturally fit our instructional needs.We have found that student submissions -- a style of interaction whereby the instructor poses a question written on a slide and displayed on a tablet in front of each student, then students write their answers in digital ink and submit back to the instructor -- are a powerful tool for supporting the learning environment we aim to create in the classroom. We show that student submissions can help the instructor to engage all students, not merely the vocal ones, and to emphasize the value of diversity of opinions. They also enable immediate feedback from students to instructor -- something difficult in an environment without technological enhancements but which contributes to an improved understanding of everyone's needs and expectations.The discussion of how we used student submissions to support these pedagogical techniques may be relevant to educators interested in fostering student learning through creative uses of technology, as well as to instructors looking to expand their repertoires of teaching methods in software engineering and in other similar subjects.
