Dichotomous Keys and Learning Objectives

The video tutorial outlines a six-day unit on dichotomous keys for seventh and eighth-grade life science classes. The unit is designed using a dynamic instructional model and includes activities like grouping exercises, iMovie tutorials, and PowerPoint simulations. The classroom environment supports both individual and group work, with specific learning objectives focused on creating and interpreting dichotomous keys. Influenced by educational philosophies of Vygotsky, Bandura, and Gagné, the unit employs strategies that emphasize group collaboration and cognitive effort. Gagné's nine events of instruction guide the teaching process, ensuring students engage in hands-on activities and receive feedback. The unit concludes with students becoming proficient in using and creating dichotomous keys, supported by various technologies.
