Applied Behavior Analysis (ABA) therapy is one of the most effective, evidence-based approaches for helping children with autism and other developmental challenges learn essential life skills. ABA therapy uses principles of behaviorism to increase positive behaviors and decrease unwanted behaviors. The foundation of ABA therapy rests on a variety of techniques, and among the most significant are the teaching methods used to help children learn new skills.
There are two core teaching methods in ABA therapy: Discrete Trial Training (DTT) and Natural Environment Teaching (NET). Both methods are widely used, but they differ in their approach, environment, and how they promote learning. Each method has unique strengths and applications, and understanding these differences is key for parents, caregivers, and therapists working with children on the autism spectrum.
In this article, we will take a closer look at each of these teaching methods, providing an in-depth exploration of their principles, benefits, and how they are applied in therapy. Whether you’re a parent considering ABA therapy for your child or a therapist looking to refine your methods, this guide will help you understand how DTT and NET contribute to the success of ABA therapy.
Discrete Trial Training (DTT): A Structured Approach to Learning
Discrete Trial Training (DTT) is one of the most commonly used methods in ABA therapy, particularly for children with autism. It’s a highly structured, systematic approach to teaching that breaks down complex skills into smaller, more manageable tasks. DTT follows a clear, predictable structure, making it an ideal method for children who thrive in structured environments.
1. How DTT Works
DTT is based on the principle of breaking tasks into small steps and providing immediate reinforcement for correct responses. A typical DTT session follows a simple cycle:
- Antecedent (Prompt): The therapist gives an instruction or prompt. For example, “Touch the red card.”
- Behavior (Response): The child responds to the prompt by completing the requested task. In this example, the child would touch the red card.
- Consequence (Reinforcement): The therapist reinforces the child’s correct behavior with immediate praise or a preferred item, such as a toy or a snack.
This cycle is repeated several times during a session to promote skill mastery. The therapist provides consistent, structured opportunities for the child to practice new skills and gradually increases the complexity as the child masters each level.
2. Benefits of DTT
- Highly Structured: DTT’s clear, step-by-step approach is effective for teaching children who need structure to thrive.
- Measurable Results: Progress is tracked through detailed data collection, which helps therapists monitor the child’s advancement and adjust the intervention as needed.
- Efficient Skill Mastery: By breaking skills into manageable components, DTT allows children to achieve mastery in one step before moving on to more complex tasks.
3. When to Use DTT
DTT is particularly effective for teaching discrete skills such as:
- Language and communication (e.g., asking for help, labeling objects)
- Academic skills (e.g., identifying shapes, numbers)
- Self-help skills (e.g., brushing teeth, dressing)
This method is often used in controlled, one-on-one settings where the child can focus without distractions. It is best used when a child needs to learn specific, well-defined skills in a structured environment.
Natural Environment Teaching (NET): Learning in Real-Life Contexts
In contrast to DTT, Natural Environment Teaching (NET) focuses on teaching skills in a more natural, unstructured setting. NET takes advantage of real-life opportunities and the child’s natural interests to teach new skills. This method promotes learning through interactions and experiences that are meaningful and applicable to daily life.
1. How NET Works
NET is child-centered and relies on the child’s natural curiosity and interests to guide the learning process. The therapist follows the child’s lead during activities, using these moments to teach skills in a way that feels relevant and engaging. Here’s how NET typically works:
- Child-Led Learning: The therapist uses the child’s interests to initiate teaching moments. For example, if the child is playing with a ball, the therapist might use the game to teach concepts such as color recognition, turn-taking, or social greetings.
- Natural Reinforcement: Reinforcement is provided immediately after a desired behavior, and the rewards are typically natural to the activity. For example, if the child asks for help, the therapist might immediately give them the item they requested.
- Generalization: One of the main goals of NET is to help the child generalize the skills they learn during therapy to real-life situations. This helps children use the skills they learn in therapy at home, in school, or in the community.
2. Benefits of NET
- Real-Life Application: By teaching skills in natural settings, NET ensures that the child can use these skills in everyday life, making the learning process more meaningful.
- Increased Motivation: Since NET taps into the child’s natural interests, it helps increase motivation, which can lead to more successful learning.
- Improved Social Skills: NET often focuses on teaching social interactions, such as how to make requests, share, or greet others. This is key for fostering communication and social development.
3. When to Use NET
NET is particularly useful for teaching:
- Communication and social skills (e.g., asking for help, making eye contact)
- Daily living skills (e.g., preparing snacks, cleaning up toys)
- Problem-solving (e.g., how to handle frustration during a game)
This method is best used in natural settings where the child interacts with family members, peers, or caregivers, allowing them to learn in a more organic environment.
Key Differences Between DTT and NET
Though both DTT and NET are essential components of ABA therapy, they differ significantly in their approach to teaching. Here’s a quick breakdown of their key differences:
| Aspect | Discrete Trial Training (DTT) | Natural Environment Teaching (NET) |
| Structure | Highly structured with clear steps | Flexible and child-centered, based on natural interactions |
| Learning Environment | Controlled, often in a therapy setting | Real-world, natural environments (home, school, community) |
| Focus | Mastering discrete skills in small steps | Generalizing skills to real-life situations |
| Reinforcement | Immediate, consistent reinforcement | Natural reinforcement based on the child’s actions |
| Target Skills | Academic, language, and specific life skills | Social, communication, and functional skills |
Combining DTT and NET for Comprehensive ABA Therapy
In practice, DTT and NET are often used together to create a balanced and comprehensive approach to learning. While DTT provides a structured, systematic method for mastering specific skills, NET helps children apply those skills in real-world settings. By combining both methods, ABA therapists can help children develop a wide range of skills that will serve them in both structured and unstructured environments.
For instance, a child might first learn how to request items using DTT, and then practice using that skill in natural settings, such as asking for help during playtime with peers (NET). This approach ensures that skills are both learned and generalized effectively.
Conclusion
Both Discrete Trial Training (DTT) and Natural Environment Teaching (NET) are highly effective teaching methods in ABA therapy, each offering distinct advantages. DTT provides the structure and clarity needed for mastering specific skills, while NET ensures that children can generalize these skills to real-world situations. When used together, these methods provide a comprehensive and balanced approach to learning.
