For students with learning disabilities (LD), note taking during lectures and discussions is a difficult task. Many students have difficulties with listening comprehension and written expression, two important skills vital for successful note taking during teacher lectures. Note taking is a cognitively demanding task whereby students must temporarily hold/rehearse incoming verbal lecture information, quickly construct representations into meaningful bits of information that can be recorded, and then transcribe the bits of meaningful information onto paper before the information is lost and before processing any new incoming information. Despite the difficulty of this task, smartpen technology can aid students during note taking by storing verbal lecture information and then syncing it up when students amend their partial notes. This article provides an overview of a smartpen strategy and a guide for teachers to implement this assistive technology in their classroom and improve the note taking of students with LD.

This paper presents an activity that engages students in model-based reasoning, requiring them to predict the behavior of the trp and lac operons under different environmental conditions. Students are presented six scenarios for the trp operon and five for the lac operon. In most of the scenarios, specific mutations have occurred in genetic elements of the system that alter the behavior from the norm. Students are also challenged to relate their understanding of operon behavior to the “Big Ideas” of homeostasis, evolution, information, interactions, and emergent properties. By using operons to teach students to reason with models of complex systems and understand broad themes, we equip them with powerful skills and ideas that form a solid foundation for their future learning in biology.
