Published: March 2021

AbstractAn effective online learning model that does not burdensome students is a hot topic of discussion in the current pandemic era.This research is a qualitative descriptive study that aimed to know the online learning models of Mathematical Statistics and Real Analysis that are effective, efficient, and not burdensome from the student’s perspective. The subjects of the research were all students who are studying Mathematical Statistics and / or Real Analysis,namely 63 students of Mathematical Statistics and 52 students of Real Analysis. The entire research subjectswere gave a survey through the Google Form to find out online learning models that best suits students. Then the survey results were analyzed based on online learning models with the largest selection percentage. The results showed that online learning models of Mathematical Statistics and Real Analysis courses that are effective, efficient and not burdensome for students is a learning model combining YouTube and WhatsApp media. Based on follow up interviews, there are many reasons why this model was chosen from other learning models such as video conferencing, one of the reasons is because this media needs less quota and is interspersed with question and answer discussions with the media that are commonly owned by students. Even when students are faced with situations where they will be given unlimited quota, students in both classes still consider the most effective and efficient learning model is to combining YouTube and WhatsApp.

Some pre-service teachers who are studying give less effective perceptions regarding the implementation of online learning during the Pandemic period. Pre-service teachers today belong to a generation of digital natives (DNG) who are very familiar with technology and have unique characteristics, so it is very important to analyze their online learning behavior to design effective online learning. The purpose of this study was to analyze the online learning behaviors of digital natives reviewed from perceived fits, attitudes, and self-efficacy. Survey research was used to analyze the phenomenon of DNG’s online learning behavior and identify the factors that influence it. The instrument in the form of a questionnaire consists of 49 statement items on a scale of 5. Of the 152 polls collected, only 148 were valid. Quantitative and qualitative descriptive analysis was used for data analysis. The results of this study showed that all components of DNG’s online learning behavior had relatively high average scores except the interaction component through online discussion forums. The causes of low interaction through online discussion forums were DNG less active, lack of enthusiasm, easy to give up, difficult to move on, and network constraints. The conclusion of this study was an in-depth analysis related to perceived fits, attitudes, and self-efficacy producing phenomena and are variables capable of explaining the variables of DNG online learning behavior. The results of this study can be used as the basis for further research, namely related to the development of online learning models for the DNG.

AbstractThis paper explores a group of primary teachers’ knowledge and perspectives about multimodal text and its usage in teaching critical reading skills for upper primary students in Surakarta, Indonesia. This case study explores a group of primary teachers’ knowledge and perspectives about multimodal text and its usage in teaching critical reading skills for upper primary students (students of grades 4, 5 and 6) in Surakarta, Indonesia. A focus group discussion (FGD) was conducted among 30 primary teachers and 10 school principals by using open-ended inquiries. The discussion administered several topics related to teachers’ perspectives about multimodal texts, teaching critical reading instructions, and the application of multimodal text in upper primary learning. The results of the research shows that text-based learning in the primary curriculum was mostly using written text with minimum illustration and often was only supported by a video from the internet. Most participants confirmed that they develop upper primary students’ critical reading skills by asking students to retell, finding key information, discussing the main ideas, and mostly answering questions about the text they read. The conclusion of the research is that the implementation of multimodal text in upper primary learning was limited to written text with illustrations, posters, advertisements, and video or animation videos from the internet. The implication of this research urges teachers to use multimodal texts to enhance critical thinking skills.
