Joint Productive Activity Method (JPAM) made use of collaboration to attain a certain goal in teaching and learning process. This study was conducted to: (1) determine the students’ level of problem-solving skills and interest towards Mathematics before and after exposure to JPAM and for those exposed to non-JPAM in terms of: pretest score, post-est score, and retention test score; and (2) ascertain whether there is a significant difference in the problem-solving skills acquired and interest towards Mathematics between those who are exposed to JPAM and those who are not. This study was conducted at Kiburiao National High School, Kiburiao, Quezon, Bukidnon. The chosen participants were the grade 11 students. The findings of the study showed that students’ problem-solving skills were very low in their pretest result but the posttest and retention test showed a remarkable improvement. Thus, it can be said that students’ problem-solving skills when exposed to JPAM were significantly higher than those who were not. Highly significant difference was observed between the two groups as to the students' level of interest in Mathematics. The increase in students' interest in Mathematics of those exposed to JPAM was better compared to those exposed to non-JPAM.
