Mississippi CTE Curriculum Framework Page 19 of 87 Best Practices Innovative Instructional Technologies Classrooms should be equipped with tools that will teach today’s digital learners through applicable and modern practices. The diesel service technician educator’s goal should be to include teaching strategies that incorporate current technology. To make use of the latest online communication tools—wikis, blogs, podcasts, and social media platforms, for example—the classroom teacher is encouraged to use a learning management system that introduces students to education in an online environment and places more of the responsibility of learning on the student. Differentiated Instruction Students learn in a variety of ways, and numerous factors—students’ background, emotional health, and circumstances, for example—create unique learners. By providing various teaching and assessment strategies, students with various learning preferences can have more opportunity to succeed. CTE Student Organizations Teachers should investigate opportunities to sponsor a student organization. There are several here in Mississippi that will foster the types of learning expected from the Diesel Service Technician curriculum. SkillsUSA is an example of a student organization with many outlets for diesel services. Student organizations provide participants and members with growth opportunities and competitive events. They also open the doors to the world of diesel services technician careers and scholarship opportunities. Cooperative Learning Cooperative learning can help students understand topics when independent learning cannot. Therefore, you will see several opportunities in the Diesel Service Technician curriculum for group work. To function in today’s workforce, students need to be able to work collaboratively with others and solve problems without excessive conflict. The Diesel Service Technician curriculum provides opportunities for students to work together and help each other complete complex tasks. There are many field experiences within the diesel services curriculum that will allow and encourage collaboration with professionals currently in the diesel services field. Work–Based Learning Work-based learning (WBL) is an extension of understanding competencies taught in the diesel services technician classroom. This curriculum is designed in a way that necessitates active involvement by the students in the community around them and the global environment. These real-world connections and applications link all types of students to knowledge, skills, and professional dispositions. WBL should encompass ongoing and increasingly more complex involvement with local companies and industry professionals. Thus, supervised collaboration and immersion into the industry around the students are keys to students’ success, knowledge, and skills development.
