(Topic 4 Task 2 Video) Classroom Reinforcement & DNA Replication

Aug 19, 2025

Overview

This lecture focused on implementing positive reinforcement strategies in the classroom, especially the PBiS four-to-one method, and included a brief discussion on DNA replication and classroom routines.

PBiS Four-to-One Strategy

  • The PBiS (Positive Behavioral Interventions and Supports) four-to-one strategy uses four positive statements for every one corrective statement.
  • Positive statements acknowledge student behaviors that meet expectations or follow procedures.
  • Corrective statements address behaviors that need improvement, with a calm and even tone being important.
  • Positive reinforcement helps create a more positive classroom environment and encourages student engagement.

Examples of Positive and Corrective Statements

  • Positive statement example: "Thank you for getting your paper out."
  • Corrective statement example: "Can you get your starter out for me?" followed by praise when the behavior is corrected.

DNA Replication Discussion

  • Replication means making an exact copy of something, such as DNA.
  • In the lesson, DNA replication is described as making an exact duplicate, not just similar.

Classroom Procedures and Participation

  • Students are thanked and acknowledged for following procedures, such as keeping phones away, raising hands, and bringing supplies.
  • Participation and following steps are encouraged and sometimes rewarded (e.g., extra credit).

Homework

  • Students are assigned to complete problems one through four as homework.

Key Terms & Definitions

  • PBiS β€” Positive Behavioral Interventions and Supports; a system for promoting positive behavior in schools.
  • Positive Statement β€” A comment that acknowledges appropriate or expected behavior.
  • Corrective Statement β€” A comment intended to address and correct undesired behavior.
  • Replication β€” The process of making an exact copy; in biology, refers to copying DNA.

Action Items / Next Steps

  • Complete homework problems one through four.
  • Check and update your notes as directed.
