The Development of On-Time Assignment Submission Behavior of Matthayom 2 Students Using a Stamp Point Collection Reinforcement System at Patongprathankiriwat School, Hat Yai District, Songkhla Province

Abstract

The objectives of this study were to 1) study the effect of positive reinforcement using the reward stamp point scrapbook on the on-time submission behavior of Matthayom 2 students, and       2) compare the submission behavior before and after the use of positive reinforcement. The sample group was 30 students of Matthayom 2/1 for the 2025 academic year at Patong Pratong Kiriwat School. The learning management plan has a consistency index value of 0.89–1.00. Stamp Points Book         0.83–1.00 Submission Behavior Observation Form 0.67–1.00 and Weekly Submission Record Form     0.67–0.92 data were analyzed using percentages, mean, standard deviation, and T tests. The results showed that before the use of reinforcement, most students had moderate to low submission behaviors. After using the stamp point book to redeem prizes. The average post-trial score was statistically significantly higher than before the trial at .05, reflecting that positive reinforcement was effective in promoting on-time submission behavior.

The study found that prior to the intervention; most students exhibited moderate to low levels of assignment submission behavior. After implementing the stamp collection reward system, both punctuality and assignment quality improved substantially, with 90% of students reaching an excellent level and none remaining in the moderate to low categories. Moreover, the post-intervention mean score was significantly higher than the pre-intervention score at the .05 level, indicating that positive reinforcement effectively promoted punctual assignment submission behavior.
