Imagine you are conducting fieldwork and discover two groups of mice living on opposite sides of a river. design an experiment to determine whether or not these two groups belong to the same species. include some of the flaws of your design. what if you could not disturb the mice at all? how would that effect your experimental design? (hint: you might want to think about previous lectures to heip you design your experiment.) if they are two separate species what two things must have occurred in orderfor them to have become separate species?

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
