The delivery of lie detection course in criminology is being challenged by several problems, such as lack of instruments to be used, student-to-instrument ratio, non-functional instruments, and others, which affect the delivery of instruction of the said course. Thus, the course outcomes of the said course may only sometimes be achieved. To address the identified issues, the researcher proposed a system called PolyTech. This system is a web-based application that will aid the delivery of lie detection course. The researcher used experimental research design and conducted pre-survey interview to concern faculty members. Also, examination, survey, and practicum were conducted among respondents, specifically students from DCCP, CCDC, and UC. T-test, ANOVA and Post-hoc were used to analyze the collected data. In summary, design considerations in developing the features of PolyTech include information requirements and architectural design. As to the impact of PolyTech on students, test, survey and practicum results show that PolyTech significantly impacts students' performance. This means that PolyTech significantly impacts the student's academic performance through statistical analysis. Thus, there is a significant difference in the knowledge and skills of students who used PolyTech and those who used the traditional method. The integration of PolyTech helped achieve the course outcome of the Lie Detection Course. Hence, it is effective and advisable to be used and adopted by criminology institutions with no access to lie detection instruments and those that has an access to the instruments but not functional after sometime.
