Educational Summary
Prefix: Base Word Builder is an interactive, high-feedback literacy tool designed to strengthen morphological awareness and structural word analysis in elementary and middle school students (specifically grades 3 through 5).

Core Educational Objectives
Morphological Mastery: Direct instruction and practice on five high-frequency prefixes:
mis- (wrong / incorrectly)
non- (not / absence of)
over- (too much / excessively)
under- (too little / beneath)
sub- (under / below)

Contextual Vocabulary Application: Students do not memorize prefixes in isolation; they analyze sentence-level context clues to determine which prefix logically modifies the target base word.

Dual-Coding Literacy Support: Audio synthesis (Web Speech API) and sound feedback (Web Audio API) ensure accessible, multi-sensory reinforcement for visual and auditory learners alike.

Immediate Remediation: Immediate feedback provides explicit explanations (e.g., “The prefix mis- means ‘wrong’. Misplace means to put in the wrong place”), cementing standard language rules and deepening vocabulary comprehension.
