The Effect of Investigation Multiliteracy Method and Prior Ability on Learning Outcomes of Constructing Explanatory Texts Among Eleventh-Grade Students at SMA Posigadan State Senior High School

Abstract

This study aims to describe the learning outcomes of constructing explanatory texts among eleventh-grade students taught by investigating the multiliteracy and conventional methods, the difference in learning outcomes of students taught by investigating the multiliteracy and conventional methods for those with a high and low prior ability, and the effect of investigation multiliteracy method and prior ability on learning outcomes in SMA Posigadan state senior high school. Furthermore, an experimental method was employed with a 2x2 factorial design. It was shown that (1) students taught by the investigation multiliteracy method got higher learning outcomes (an average score of 79) than those who studied using a conventional method with an average score of 62.81. (2) the average learning outcome of students with the high prior ability and taught by the investigation multiliteracy arrived at 78; no major difference from those with the high prior ability and relying on a conventional method (an average learning outcome of 75). Likewise, the average learning outcome of students with the low prior ability and taught by the investigation multiliteracy reached 52.81; no major difference from those with the low prior ability and studying with a conventional method (an average learning outcome of 46.94). (3) the p-value in the interaction between the investigation multiliteracy method and prior ability got 0.007 or less than α = 5%. Thus, H0 was rejected and accepted H1, meaning that the investigation multiliteracy method and prior ability influence students’ learning outcomes.
