eLearning Instructional Designer

Wendianne Grant

Wendianne is an instructional design professional with a variety of experiences in teaching, educational content creation, software development, and visual media creation, including significant projects for major K–12 publishing companies. Wendianne has a B.S. in Art Education, taught for four years, served as an Instructional Designer for McGraw-Hill Education, and freelanced for numerous educational publishing giants before landing at Math Made Visible.

Wendianne first knew she wanted to work in the publishing industry during a second-grade field trip to one of the nation’s oldest publishing companies. After 25 years in the industry now, Wendianne has often thought about what she might tell her younger self if she could go back to that initial field trip. She’d likely mention the excitement of creating nationally distributed educational products for well-known publishing companies, some print and many digital. More likely, Wendianne would spend time talking about a few of the experiences that, strung together, illustrate why she loves what she does. She’d share how a gap in a client’s product line gave her the opportunity to write science songs to be heard and sung by children across the country. She’d explain how she learned the importance of listening to the opinions of young people while field testing. She’d laugh about how one freelance contract listed her job title as “Oracle” based on her knowledge of the authoring platform she’d be teaching others to use. Most of all, she’d hope that second-grade Wendianne would be pleased with the way her grown-up self spends each workday striving to develop highly effective and engaging educational materials. With any time left, she might attempt to define “digital offering.”
