This paper is a report of an investigation in which mobile technologies were used during large lecture-type sessions in tandem with the Textwall™ software. This online program is able to receive and present messages from students' devices that the lecturer may then share. It also can be used to collect student votes on multiple-choice questions, facilitating dynamic formative assessments during class. A study has been undertaken around the "MyWallMate" mobile application. This program has been developed by Liverpool John Moores University to expedite the process of sending messages and votes to Textwall™. Results of this study indicated that students had a positive reaction to both Textwall™ and the "MyWallMate" application. They reported being more comfortable in expressing their opinions via the "MyWallMate" mobile application and felt that using mobile technology within their lectures enhanced their learning. It has been concluded that the use of mobile technologies and BYOD-type approaches are avenues worth further exploration in global higher education.
