Online learning becomes one of the most common educational methods during Covid-19 pandemic. There occurred too many issues and challenges during online education. The absence of pedagogical approaches caused ineffective courses to facilitate learning of students. While designing lectures, instructors should consider the cognitive load of students. The more increased cognitive load leads to ineffective learning outcomes. There are many ways to reduce cognitive load when designing instructional online courses. Advance organizers are one of the pedagogical tools that are used to reduce cognitive load of students. For a long time, advance organizers are used to help students organize their cognitive architecture by linking students’ prior knowledge and new learning material. In this study, the use of different types of advance organizers which are narrative and graphical advance organizers are investigated. Sequential explanatory design model is used with the 15 undergraduate students who registered the course entitled Research Methods‖ in a public university participated to the study. Qualitative data are collected to get more detail of quantitative data results. In order to reveal students’ opinion about different advance organizers, a mixed method research design was conducted. To analyze the results, paired sample t - test was used to test students' performance on the achievement test. T-test results showed that there is no significant difference between two AOs on achievement test scores. In addition, as a follow up, 5 participants were invited to answer open ended questions and interview. The constant comparison method was used to analyze qualitative data. The quantitative analyze results showed that students take advantage from both types of AO. The results indicated that the mean of graphical AO score (M = 6.87, SD = 2.13) was not significantly different than the mean of narrative type AO score (M = 6.80, SD = 2.04), t(14) = .096, p < .01. Qualitative analyze helped to get deeper understanding of students’ opinions about usage of AO. Students pointed out that graphical AOs are useful to catch key point during course, process learning content and connect concepts.
