Back Bay Systems has over 8
years experience developing ABA / Discrete Trial Training software
programs for autistic students. Computer based instruction has
many advantages but most commercially available instructional
software is not designed with the principles of precision teaching
and behavior analysis in mind. Back Bay Systems can deliver powerful
programs using your existing classroom curriculums combined with
the benefits of computer based instruction in an ABA environment.
What are the benefits of computer based
Discrete Trial Training?
- Self-paced instruction. Computer based instruction
allows each student to learn skills at his/her own pace. The
faster students are not held back by the pace at which other
students in the class are learning and the slower students are
able to move at a pace that is comfortable and efficient for
them. Using such software, students can be working on different
levels at the same time.
- Immediate feedback on each learning trial.
Typically, instruction is presented to the student on one new
skill at a time and the student is given a series of problems
or questions that both teach and test for this one new skill.
After each problem the student receives immediate feedback (knowledge
of whether he/she was right or wrong and, in some cases, what
the correct answer is). The immediacy of this feedback is a
very important feature that enhances learning. It contrasts
with the significant delays that a student experiences in normal
classroom instruction when he/she passes in a quiz or test paper
and receives it back in corrected form a few days later.
- Prompting. Programs may be designed with
a unique prompting system that enables the student to make use
of a graded series of prompts (hints) that will help him/her
answer the problem correctly without giving away the complete
answer. The prompts include such things as the length of the
word in question, the number of letters in the word, the first
letter, last letter, interior letter(s), etc. Prompting schemes
facilitate the minimization of errors and have proven to be
very popular with students.
- No advancement until each question is answered correctly.
Programs may require that the student give the correct answer
to each question in the current chapter before he/she is allowed
to advance to the next chapter. In other words, not only is
the student given immediate feedback as to whether each answer
is correct not, but also the student required to answer each
question correctly at least one time.
- No advancement until mastery of current skill.
Programs may also require the student to master each skill fluently
before he/she is allowed to advance to learning the next skill
in the sequence. This eliminates the problem in which a student
fails to learn a particular skill and, as a result, later finds
him/herself hopelessly behind as the rest of the class progresses.
- Time based skill measurement. Skill mastery
may be measured by rate correct/incorrect rather than by percent.
Rate is a more sensitive measure than percent correct because
it takes into account time and enables the teacher to bring
the student to not only to the mastery a given skill but, more
importantly, to fluency (fluent mastery) of that skill.
Computer based positive reinforcers.
Positive reinforcers (rewards) may be awarded to students
at at various milestones throughout a program such as achieving
mastery over a skill, completion of a skill level, etc. The
student may be given access to a computer game, audio or video
reward or activation of Back Bay Systems' capsule
- Progress display. Displays, for the teacher,
the student’s current rates correct and incorrect. Programs
may create a distinctive display on the student’s screen
that enables the teacher to notice, at a distance, whether the
student is working at or above the desired rate correct or not.
Dawdling or wasting time can be detected immediately and corrective
