This is a complete set of interactive PowerPoint Slides for High School Biology that is geared toward specific state standards. You may select the standards from any of the 50 states. The lessons are divided into nearly 100 manageable “chunks” of from 3 to 12 slides. This way the educator can use any individual topic in the sequence that best fits their curriculum. The flexibility of being able to integrate all or some of the lessons and use them at the most appropriate time is one of the best features of this program. The way the topics are broken into small, manageable pieces is also a great feature. This would allow for remediation with students who need extra time with a topic or pre-teaching a topic for students who need additional support. The animations are well done and will keep the interest of high school students. Age-appropriate animations, which won’t remind students of kindergarten, are used throughout the program. Video sequences add depth; practice problems enhance the lessons; and important terms can be clicked on to reveal more information. Some of the slides have teacher notes already embedded with information for the instructor such as insights about diagrams and instructional suggestions. Overall this is a highly useful program for biology teachers. If I were a new teacher, I could design my entire course around these slides. As an experienced teacher, I can use these slides to add depth and breadth to my existing PowerPoint slides. This product takes the “hard part” out of lesson development and gives the teacher a complete set of ready-to-use lessons. This is a great resource that I and my students have enjoyed for the past few weeks.
