This research aimed at knowing the effectiveness of online learning design with an e-portfolio approach in increasing self-efficacy in speaking ability. Seventy-seven students were involved in this study. They are in the second semester of a vocational college in Business Administration Department in the academic year 2020/2021. This research is experimental research with implementing paired samples t-test as the measurement tool in knowing the effectiveness of e-portfolio based learning by finding the t score and the sig value before and after the implementation of the teaching method. The result of this study showed that e-portfolio based learning had a significant effect on the student's self-efficacy in their speaking ability. It was indicated by the value of the sig and t result from paired samples t-test analysis which was showed 0.000 as the sig value and -20.551 as the t count. The result of sig value which is below 0.05 and the t-count which is above t-table were clear indicators to argue that e-portfolio significantly impacted the student's self-efficacy in speaking ability. In this case, the variables of self-efficacy in speaking ability were improved significantly by the implementation of e-portfolio based learning. Even the implementation of e-portfolio brings many positive impacts on the students, some limitations lie on this method implementation. The limitation of this method lies in the time execution and the number of students who are taught by the lecturer.

English is one of the primary subject that was taught in Electronic Engineering, Politeknik Negeri Bali, which includes speaking, writing and listening. Other than speaking, writing also become one of the most challenging subject in Electronic Engineering. To overcome the low writing skills of students and create pleasant learning atmosphere during the Covid 19 Pandemic, the authors want to try out learning method, namely Cooperative Learning Method with online media in the form of whatsapp. This research is a quantitative research with quasi experimental approach. The groups used in this study consist of two groups namely the experimental group using Whatsapp Cooperative Learning methods and the control grouos using the conventional method. The data collection technique in this study was in the form of a questionnaire and given to the students in both classes. From the data, it can be concluded that learning with the Whatsapp Cooperative Learning method is more effective to be used in teaching writing. It can be seen from the value of 2 of -2, 087 with Sig 0,037< 0,05 means that there is significant difference between the control class and the experimental class. This significant difference can be said as the result of the use of Whatsapp Cooperative Learning in class.

The concept of Merdeka Belajar and Kampus Merdeka has been attracting much attention of language lecturers and researchers in higher education institution. The program of Ministry of Education and Culture Republic of Indonesia contributes to some questions on how the English learning should be designed and undertaken. This article would like to address how the teaching of English for vocational purposes (EVP) in polytechnic vocational institution. Specifically, it was in an attempt to develop of EVP teaching model. In this study the focus was given to the development of model, including developing material, leaning syntax and assessment tool. Material development included that of module used to facilitate the learning of EVP at vocational university. The result of the development pursuant to in the-class short experiment involving students successfully contributed that the development of visible, compatible and applicable vocational education materials consists of Snapshot, Project Preparation, Gathering Information, building up a Dialog, Making Dialog Using the Given Card, and Role Play. The lesson plan or learning syntax contained four main stages, such as preparation, realization, presentation and evaluation. And the assessment tool comprised of card and scoring rubric. Stages of learning include 'inventorying expressions or sentence structures', 'building a dialog', 'performing dialog', and 'giving feedback'. This was a stage where concept of learning language based on project activity was merely explained. It was emphasized in order for the students to really comprehend how the approach works, what processes were required to pass, and what purpose was lied behind it. The activity aimed at connecting students' (prior) knowledge with context. In addition, students were trained to finally build up a new concept using their prior knowledge.

The dictionary of taxation accounting terms plays an important role for vocational students as an independent learning tool as it provides a specific list of vocabulary to support their study compared to a general dictionary. This learning media was developed based on the adaptation of the ADDIE Model (E. Forest, 2014). The implementation phase was carried out using an experimental research method applied to students majoring in Taxation Accounting. Prior to and following the use of independent learning media in the learning process, quantitative data were gathered from the results of pre-test and post-test. The integrated media is a dictionary of tax accounting terms that is equipped with an online self-evaluation feature through Quizizz application. To determine the effect of using a dictionary on improving student achievement, the results of the pre-test and post-test assessments were analyzed using the SPSS statistical program. The One-Sample Kolmogorov-Smirnov Test was used to test the normality of the pre-and post-test results, and the paired sample t-test was used to determine whether there was a significant difference in the students' performance before and after the use of the dictionary. Meanwhile, scale-type questions from an online survey in the form of a google form were used to collect qualitative data and the results were analyzed to determine student perceptions of learning academic reading and competencies. The questionnaire responses highlight that students had some difficulty comprehending academic texts on taxation and accounting due to the complex vocabulary. According to statistical analysis, the dictionary combined with interactive practice via the digital platform Quizizz had a positive impact on student achievement.

In an era where learning cannot be separated from technology, there are various Android-based applications that are very helpful, interesting and make learning adapt to the learner's time. Learning media is the learning source component that is able to stimulate students to study (Arsyad: 2005). In this paper the learning media is application. One such application is the Cake application. This application is a learning application that deserves to be tested because it has several advantages. One of the advantages of using learning applications is that there is no limited space and time for learners to learn. Learning is no longer limited to lecture rooms or lecture time. learning can be anytime and anywhere. The purpose of this research is to find out whether the Cake application has an effect on students who use it, especially in the speaking field, more specifically the pronunciation. This research is a type of quantitative research with a quasi-experimental approach. The design used is "Pretest – Posttest Non-Equivalent Control Group Design". The groups used in this study amounted to 2 groups, namely the experimental group using online learning and the control group using online learning as well but added with the application of Cake. In this study, according to determine the experimental class and control class, random assignment was done, namely, the selection was made randomly to choose the class. This research will provide benefits for teachers who want to try to apply the method so that it will be a reference later in the future.
