JELLT Vol.VI, No.1 - 2022 79 THE EFFECTIVENESS OF MINDLY APPLIED IN TEACHING READING COMPREHENSION Gina Larasaty; Putri Fitriyani Universitas Wiralodra; Universitas Wiralodra gina_larasaty@unwir.ac.id; putrifitriyani@gmail.com Abstract Coronavirus has forced schools to teach online, where learning uses a variety of applications, one of which is Mindly. Therefore, the writer is interested in conducting research to find out the effectiveness of Mindly in teaching reading comprehension. Grounded in quasi-experiment method with the design pre-test and post-test, this research is conducted on the 26 students from 2 classes at SMPN 1 Lohbener. The result of the pre-test students score in control class showed that the average was 42,77 and the pre-test students score in experiment class showed the average was 47,08. The post-test total scores in control class showed the average was 60,62. And the result of post-test the total scores in experiment class showed the average was 59,08. Then, the statistical analysis showed that the value tobs was 0,9999 while the value of ttable 0,6 which means that the value of tob higher than ttable 0,9999 > 0,6 (tobs > ttable). From the result of statistical analysis, it can be concluded that tobs was higher than ttable (tobs > ttable) it means that Alternative Hypothesis (Ha) was accepted while Null Hypothesis (Ho) was rejected. It means that using Mindly does not give positive effect to students’ reading comprehension. Keywords: Mindly, Effectiveness, Reading Comprehension INTRODUCTION Reading is one of the language skills that should be studied and mastered by students to get information from the texts (Haerazi & Irawan, 2020).Unfortunately, there is a new problem in reading, especially now the learning process has changed drastically which was previously offline and is rarely forced to learn online. The problem of reading comprehension is still very difficult for students to understand in offline classes, especially now that students learn in online classes. And in previous research there were several researchers researching in reading strategy in offline class. In teaching reading comprehension there are some strategy, one of them is Mind Mapping. According to Kotcherlakota, Zimmerman, & Berger (2013), “mind maps help students clarify their thinking and lay the foundation for in-depth expertise related to their research focus, review of the literature, and conceptual framework”. In the implementation of Mind Mapping Strategy can use online or technology accordance with in this modern era. Using paper mind maps seem to be time-consuming because students need to erase many times and rewrite again and again (Erdogan, 2008). With the development of technology, mind mapping strategy developed into Mindly. Mindly is one of the most beautiful mind-mapping apps enables you to create several different mind maps for planning a project, though structuring idea. With a situation where learning is required online, so learning using applications is mostly
