1 Corinthians 9:21 states, "I have become all things to all people." That is what we have to do as teachers.... Teachers are challenged every day to educate students with vastly different learning capabilities, preferences, and interests. How does a teacher cater to all these unique learning needs while achieving school administrative goals and helping students pass standardized tests? The answer is differentiated instruction: adapting teaching methods to each individual student. GUIDE to Differentiated Instruction for Christian Educators addresses how the Great Commission and teaching are unified through differentiated instruction. Teachers need to reach all students, including the diverse and struggling learners. Beth Ackerman uses her experiences as a grade-school teacher, principal, professor, and associate dean to encourage teachers and provide strategies for implementing differentiated instruction in their classroom.
