Word Building, Frog - Excello-Recherche-Education/Kalulu GitHub Wiki

Screenshot_20180914-173546

The goal of the game is to spell a word correctly by tapping on the right letters or grapheme-phoneme units, as they move across the screen on lily pads.

The player listens carefully to a spoken word and must rebuild it step-by-step, tapping each correct sound or letter in the correct sequence. Every time the player taps the correct item, the frog moves closer to crossing the water.

Kalulu instructions: The frog wants to cross. Tap on the lily pads as they pass in front of the frog to spell the word you hear. Listen carefully!

Inputs Word List: Words range from 2 to 8 letters in length.

  • Each word is fully segmented into its grapheme-phoneme (GP) units.

⸻

Gameplay

  • The player hears a complete word.
  • They must click on the corresponding GP units in left-to-right order to spell the word correctly.
  • Completing the entire word counts as a correct response.
  • Selecting an incorrect GP at any point counts as an error.

Each GP presented comes with its own set of distractors.

⸻

Goal

  • Successfully spell 5 target words during the session.

⸻

Target Selection

  • 5 Targets are selected for each game.
  • 3 words are selected from the current lesson.
  • 2 words are selected from previous lessons where the player previously made an error (if available).
  • 1 additional word (among the 5) is selected at random from previous lessons.

⸻

Distractor Selection

  • Distractors are made for each GP, not the word, only vowels are distractors for vowels and consonants for consonants.
  • GP distractors must not share the same phoneme representation as the correct GP (e.g., "o" cannot be a distractor for "eau").

⸻

Difficulty Progression

Difficulty increases based on:

  • Number of possible appearance spots for GP units on the screen.
  • Spawn rate (speed and frequency of GP appearances).

⸻

Remediation Strategy

  • After 1 error: No change; the game continues normally.
  • After 2 errors: Kalulu repeats the instructions.
  • After 3 errors: Kalulu highlights the correct GP to guide the player.
