This study investigated the twenty first (21st) century skills and student mathematics performance
in self-blend approach (SBA). The research findings showed that the students have low
performance in their pretest, and moderate performance in both posttest and retention test.
Students have high 21st century skills before and after the intervention. Results indicated that
students exposed to SBA have performed better than students who were exposed to non-selfblend
approach (non-SBA) in terms of post-test and retention test scores. There is a significant
difference in the level of 21st century skills of the students who were exposed to the SBA and
that of students exposed to the non-SBA in terms of critical thinking and problem solving,
motivation and work ethics, ethics and integrity, persistence and resilience, leadership and
teamwork, and communication skills.
