This study determines the effectiveness of using the Mobile E-Module in Teaching Shielded Metal Arc Welding 8 on the performance of Thirty-Six (36) Grade 8 ? Courageous Students of Buenavista Integrated National High School, in the Third Grading Period of School Year 2021 ? 2022. Specifically, the researcher sought to answer the following questions, (1) What are the features of Mobile E-Module in Teaching Shielded Metal Arc Welding 8 with regards to its:(1.1) accessibility;(1.2) usability;(1.3) aesthetic value; and (1.4) suitability? (2) What is the level of student's performance as to the result of their formative test in Shielded Metal Arc Welding 8? and (3) Do the features of Mobile E-Module in Teaching Shielded Metal Arc Welding 8 has a significant effect on the student's performance in Shielded Metal Arc Welding 8. The researcher used a quantitative approach with an Experimental Research Design since the researcher chose his Grade 8 Student for the Third Quarter of School Year 2021-2022 to test the effectiveness of the Mobile E-Module in Teaching Shielded Metal Arc Welding 8. The findings of the study of the features of the Mobile E-Module in teaching Shielded Metal Arc Welding 8 in terms of accessibility is very high which means that the E-Module is accessible, in terms of usability it is very high which states that it is usable, in terms of its aesthetic value it is very high that gives it an impression that is feasible to the eye of the user and in terms of suitability it is also very high which indicate the Mobile E-Module in Teaching Shielded Metal Arc Welding 8 is suited to be used in distance learning. The student?s performance based on the result of their formative test in Shielded Metal Arc Welding 8 obtained an outstanding performance. The mean indicates that the performance of the students on the formative test was outstanding. This means that on average the students? performance was beyond high expected performance. Lastly, To identify if the features of Mobile E-Module in Teaching Shielded Metal Arc Welding 8 have a significant effect on the student's performance in Shielded Metal Arc Welding 8. Its usability and suitability obtained a lower p-value which indicates that these two features have a significant effect on students? performance in the formative test. Nevertheless, the p-value gained by accessibility and aesthetic value both suggested that these features have no significant effect on students? performance in the formative test. This meant that accessibility and aesthetic value do not influence the result of their formative test. This indicates that the features of Mobile E-Module in Teaching Shielded Metal Arc Welding 8 have a partial effect on the student's performance.
