* Explode the Code

This is my personal review of an online reading program I’ve used successfully for several years: Explode the Code Online.  It’s a giant of a program, a digital version of a highly successful series of workbooks for teaching phonics published by EPS.  The online program mirrors the 8 workbooks.  Both workbooks and online program provide systematic and sequential instruction in phonics.  Here’s a screen shot of an online sample page.  ETC online

How it works:  The program will start with an automatic assessment of short vowel sounds, which also includes segmenting sounds, isolating beginning sounds, and spelling CVC words (Book 1).  However, teachers may choose whatever starting place is appropriate for the student.  Here is an overview of the content:

  • Book 1: short vowel sounds
  • Book 2: beginning and ending consonant blends
  • Book 3: long vowel sounds, consonant digraphs and trigraphs,
  • Book 4: compound words, word endings, syllable division, syllable types
  • Book 5: word families, 3-letter blends, qu, and sounds of -ed
  • Book 6: r-controlled vowels, diphthongs
  • Book 7: soft c and g, silent consonants
  • Book 8: suffixes and endings

What kids do: There are numerous responses required for each skill, including identifying correct letter-sound associations by dragging letters or typing; reading words; spelling;  matching; answering questions; practicing vocabulary; and reading sentences.  The activities themselves range from matching pictures and words to choosing one of two sentences to match a picture.  Student voices are used throughout, the graphics are animated (changing from black and white to color), and the all the individual sounds are carefully but naturally spoken, segmented, and then blended (see Cons below for one caveat on this).  After completing each lesson, students earn one of four icons for their scorecard: an airplane, a butterfly, a ladybug, or a bee.  Earning a certain number of icons (which can be adjusted by the teacher) rewards the student with the FUN button, a page of links to online games and websites.  Students may time themselves during each lesson and check their own student summaries when they log in (for the same information that teachers get below).

What teachers get:  Each student’s progress is  recorded in detail.  Serious detail.  You can generate reports that indicate how many minutes and seconds a student worked (and the actual time they were online), their accuracy rates, problem skills, comparison to California State standards, overall progress, number of lessons mastered, and number of assessments passed.  You name it, the program measures it.


  1. The abundant repetition and built-in programing ensure that students get sufficient practice before moving to a new skill
  2. It can be used to support a special needs student in the regular classroom to reinforce special education services
  3. The continual visual and auditory representation of segmenting and blending support phonological awareness
  4. This program provides a worksheet-free way to practice phonics skills
  5. Student progress is recorded in minute detail, which is excellent for EC kids as well as those in Response to Intervention
  6. A great program for English Language Learners (ELL)
  7. It is reasonably priced; seats can be swapped out if a student leaves or masters the content and all data is preserved
  8. It is easy to use for both teachers and students
  9. Students are motivated to earn the better icons (‘airplanes’ trump ‘bees’)


  1. Kids usually find the program boring, airplanes and bees aside.  The Fix: Plan on an external motivation system or get them to buy into the importance of this practice.
  2. If a kid “goofs” off and makes multiple errors, the program will continue to repeat the activities that were completed incorrectly.  The Fix: Explain what will happen if they goof off.
  3. The program does not correct for unaccented syllables.  The syllables “but” + “ton”  are pronounced correctly on their own, but the word doesn’t sound the same when combined into “button.”  The Fix:  Use this as a teaching opportunity for blending syllables.
  4. The program can be occasionally “glitchy” due to the enormous amounts of audio and graphic files.  The Fix: Buy a better computer.

My Rating: 4 1/2 stars out of 5
