Fixed Ratio

One common schedule of reinforcement is the fixed-ratio (FR) schedule, in which a reinforcer is given after a fixed number of behaviors. For example, you might say, “As soon as you finish 10 problems, you may go outside.” Regardless of the amount of time it takes, students are reinforced as soon as they finish 10 problems. This is an example of an FR10 schedule (10 behaviors for one reinforcer). One common form of fixed-ratio schedule gives reinforcement for each behavior. This is called continuous reinforcement (CRF), or FR1. Putting money in a soda machine is (usually) an example of continuous reinforcement because one behavior (inserting money) results in one reinforcer (a soda). Giving correct answers in class is also usually continuously reinforced. The student gives a good answer, and you say, “Right! Good answer!”

Meichenbaum’s Model of Self-Regulated Learning: Meichenbaum believed that students were capable of learning how to self-regulate their behaviors. This self-regulated learning is also referred to as “cognitive behavior modification” (Slavin, pg. 114). By following the five-step strategy/procedure Meichenbaum created, teachers should be able to see improvement in student’s ability to self-instruct. The idea is to use these strategies to reduce disruptive behavior in the classroom and help the student develop independence and awareness in his or her behavioral actions. Ultimately, students who self-regulate their behaviors effectively can transfer these skills into academic fields as well, such as tracking their own academic achievements and progress. Meichenbaum’s steps for self-instruction are listed below: “1. An adult model performs a task while talking to self out loud (cognitive modeling). 2. The child performs the same task under the direction of the mod...

Social Development Theory - Lev Vygotsky In terms of popularity, Lev Vygotsky is one of the most utilized psychologist in the educational field. Stressing the importance of social learning, Vygotsky advocates a cognitive perspective that learning precedes development. According to Vygotsky’s Social Development Theory , the social interactions and experiences of an individual guides his/her development. Cognitive processes and thinking are therefore a product of socialization and one’s social behavior. One important byproduct of this is what Vygotsky termed private speech - children’s silent inner speech that guides their actions and thoughts. This inner speech is initially the incorporation of others’ speech, which children use to help themselves solve problems. Teachers often incorporate this in their teaching when they use the “I do, we do, you do” modelling instructional strategy. While this strategy is primarily used for teaching academic content, it is also a powerful tool ...
