Always look for opportunities to catch students in expectation-following behavior from the classroom expectations matrix you create.  Let students know what they did well specifically and avoid only saying "Good job!" For example, if a student has raised their hand quietly to ask you a question you can respond with, "Thank you for raising your hand quietly. That is a respectful (expectation) way to get my attention when I am teaching. Using BSP reinforces the desired behavior and leaves little doubt as to the expectation that was met. 

Other examples of BSP:
"Thank you for being safe and walking in the halls slowly to get back to class."
"You did a great job at being engaged with your work and bringing all your materials with you to my desk for group work."
"I like how you were accountable and asked me for help with your work appropriately."

Quick Tips:

• Give the praise immediately after the behavior.

• State the behavior explicitly.

• You may need to pay close attention to target students.

• For target student, intentionally arrange opportunities for students to display appropriate behaviors to provide BSP.

• Consider individual students' needs and preferences (some may not repsond well to attention.)

• Creates opportunities for positive interaction between you and students.

• Let's the students know their behavior and effort is appreciated.

• Increases the likelihood that a desired behavior will occur in the future.

• Builds trust between you and students. 

• BSP serves as a verbal prompt to any students who may not be engaging in the expectation-following behavior.
