The level of scientific literacy among students in Indonesia is still low. Teachers have attempted to improve it through the use of different teaching models, a variety of resources and technology, and incorporating a scientific approach in the learning process. Mobile-based interactive multimedia can be used as an alternative learning resource to improve students’ scientific literacy. This study aims to explore about about the potential of using mobile-based multimedia interactive to improve scientific literacy. This study employs a qualitative research with the survey as the data collection method. The population in this study were all high school students in Special Region of Yogyakarta Province, Indonesia. Meanwhile, the research sample are 10th grade students of SMA 1 Pengasih with a total number of 108 students who were selected randomly. The questionnaires distribution process was conducted online with using Google Forms after the researcher demonstrate various types of media that can be used for learning activities. The results of this study showed that the use of mobile-based interactive multimedia in learning has a great opportunity to be able to increase students' scientific literacy because in addition to high student interest, there are also many benefits that will be obtained by students, especially to make it easier for students to understand learning material.

The Covid-19 pandemic has had a very significant impact on paradigm shifts and learning activities. Currently, ICT has a great opportunity to be utilized and contribute optimally to facilitate students during learning activities during the Covid-19 pandemic. The main purpose of this research is to analyze specifically the teacher's views regarding the implementation and use of ICT-based learning media that takes place during learning from home during the covid-19 pandemic. This research design includes qualitative research. The subjects in this study were subject teachers in high schools. Data collection techniques used questionnaires, observations and interviews, with the instruments being questionnaire items, observation sheets and interview guidelines. Data from the questionnaire were analyzed by triangulation, through data reduction, data presentation, and drawing conclusions. The results showed that so far teachers use media as learning aids in the form of printed modules, and assignment sheets, besides the lecture method and presentation media also dominate in the continuity of learning activities, teachers still persist not to use ICT in the learning process, especially to support the independent learning process during the covid-19 pandemic. Innovation through the integration of ICT in the learning process is an important thing for teachers have to do, especially now that students are carrying out learning from home, so that students will remain enthusiastic and motivated to carry out a series of independent learning activities.

A formative assessment needs to be conducted at the end of each topic discussion to know the progress of some learning activity, but teachers often skip it because of limited time and cost. Plickers (Paper Clickers) is a formative assessment technology without requiring students to bring electronic devices, but rather by scanning students' responses through QR code on a card with smartphone that connected to internet. Chemistry teacher of SMK Kesehatan Wonosari was implement Plickers in formative assessment. This study aims to describe students' perception of the use of Plickers in Chemistry learning outcomes assessment in digital era. The reason for conducting this research is there is no research in Indonesia to investigate students' perceptions about the use of Plickers as an assessment of Chemistry learning outcomes. So, this study results can be used as a reference for teachers in assessing learning outcome by using Plickers. This study uses a descriptive mixed research method between quantitative and qualitative with using questionnaire instrument. This study results showed that the majority of students believed in the importance of learning outcomes assessment with Plickers because they would get immediate feedback and the learning environment become more active and enjoyable.
