Feature Function Class is a powerful visual teaching tool designed for educators, therapists, and parents working on receptive language and categorization skills. Built specifically for Feature-Function-Class (FFC) training, this app streamlines the process of presenting images and testing identification skills. WHAT IS FEATURE-FUNCTION-CLASS? Feature-Function-Class is a proven teaching methodology used in Applied Behavior Analysis (ABA) therapy and early childhood education. It helps learners identify and categorize objects by: - Features — What you SEE (color, shape, parts) - Functions — What it DOES or how you USE it - Classes — What CATEGORY it belongs to HOW IT WORKS Select any Feature, Function, or Class filter and the app instantly displays a set of images — with one image always matching your selected criteria. This creates natural teaching opportunities and quick identification trials. KEY FEATURES ◆ 300+ Pre-Tagged Images Start immediately with a library of high-quality, royalty-free images professionally tagged with features, functions, and classes. ◆ Smart Filtering Filter by Feature (spots, red, round), Function (cuts, you sit on it), or Class (animals, furniture, food). Combine filters to narrow results. ◆ Shuffle Mode Keep training fresh — Shuffle loads new images while always maintaining one that matches your filter. Cycle through your entire library without losing focus on the training target. ◆ Reorder Mode Test true recognition — Reorder keeps the same images but shuffles their positions. Perfect for confirming the learner recognizes the target, not just its location on screen. ◆ Adjustable Grid Size Scale difficulty from 2 to 8 images. Start simple and increase complexity as skills improve. ◆ Save & Load Sets Working with a client over multiple sessions? Save your image set once and reload it instantly. Maintain consistency across training sessions. ◆ Import Your Own Photos Add personal photos and tag them with custom features, functions, and classes. Include familiar objects, family members, or items specific to your learner's environment. ◆ Custom Tags Create your own feature, function, and class tags to extend the built-in library and personalize training.
