We adopted Issues and Science after spending several months researching and meeting with different publishers. When our Lab-Aids specialist came in, we worked through an activity with the whole staff. She explained how the program works, how it benefits students with the issue-based curriculum design... We were hooked from the start!
Our students love the hands-on approach to solving real-world problems through varying types of activities. Their instruction is now is group or partner oriented, they have regular, meaningful discussions, and the frequent hands-on labs keep student interest piqued!
As teachers, we love watching students have their "ah-ha" moments, as well as the organization of the units, teacher guides and materials. This program has 100% supported our implementation of the NGSS. I used to provide information, now I facilitate it.
