Physics, particularly mechanics, poses significant challenges for junior high school students, often leading to low conceptual mastery. This study assessed student performance in mechanics, identified the least mastered topics, and developed a technology-enhanced learning material to address these gaps.

Employing a developmental research design, the study was conducted in five public secondary schools in the Schools Division of Antique using random sampling. Selected Grade 10 students participated as respondents. Four research instruments were used: a 50- item Mechanics Diagnostic Test based on the K to 12 MELCs, a student feedback questionnaire, a teacher evaluation tool, and the DepEd Evaluation Rating Sheet for Non-Print Materials. Data were analyzed using mean percentage scores, and thematic coding of qualitative responses. 

The findings showed that students had a moderate overall mastery of mechanics. Projectile motion, free fall, and work, energy, and power were identified as the least mastered topics. To address these learning gaps, a mobile learning application named Phyxiom was developed. The app featured curriculum-aligned interactive lessons, simulations, guided problem-solving, and offline access. Students and teachers rated Phyxiom highly in terms of content clarity, usability, and effectiveness. Expert evaluators confirmed that the app met DepEd standards in content quality, instructional value, technical design, and accuracy.

The study concludes that Phyxiom is an effective digital tool for improving students' conceptual understanding in mechanics. It is recommended for use as a supplementary learning resource in both classroom and independent study settings to enhance physics instruction.
