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. DESIGNED FOR - ABA Therapists & BCBAs - Speech-Language Pathologists - Special Education Teachers - Early Intervention Specialists - Parents supporting skill development at home Whether you're running discrete trials, building receptive vocabulary, or working on categorization skills, Feature Function Class gives you the tools to create effective, engaging training sessions.
