Scientific approach is a teaching strategy using scientific steps in teaching subject matter at senior high school in Indonesia. Scientific approach has the characteristics of “doing science” that allows teachers to improve the process of learning by breaking the process down into steps which contain detailed instruction for conducting student learning. Although the scientific approach offers significant breakthrough in improving the quality of teaching English as a foreign language (TEFL) at Senior High School in Indonesia, there were still some obstacles faced by English teachers. This study aimed at investigating the implementation of scientific approach to teach English at Senior High School in Indonesia and problems of teaching and learning in implementing scientific approach. The data were collected through observation of teaching learning process and interview with the teachers and the students in two senior high schools in Padang, Indonesia. The findings showed that, among the five steps of scientific approach, the teachers were not able to implement the observing and questioning steps optimally yet. Meanwhile, in experimenting and associating the teachers have applied them well, and in communicating the teachers have applied them optimally.

Despite the global integration of generative artificial intelligence (GenAI) tools in higher education, limited research exists on how demographic factors such as gender and academic level shape their adoption and usage, particularly in language learning contexts outside Western settings. This study aimed to fill this gap by examining the usage patterns, satisfaction levels, and acceptance factors of GenAI tools among English major students in Indonesian higher education. Employing a mixed-methods approach, the research collected data from 277 students using surveys and structured interviews to gauge both quantitative and qualitative aspects of GenAI tool utilization. The results indicate ChatGPT, Google Translate, and Grammarly as the most utilized tools for writing assistance, language learning, and research tasks, with consistent satisfaction across demographics. Performance expectancy emerged as the most influential acceptance factor, followed by effort expectancy and facilitating conditions, while social influence played a moderate role. Qualitative findings reveal students rely on GenAI for grammar refinement, translation accuracy, content exploration, and idea generation, reflecting critical and reflective engagement. Nonetheless, concerns about overreliance and ethical implications accentuate the need for balanced integration. These findings inform tailored educational strategies, emphasizing ethical use and fostering critical thinking in GenAI adoption for English language education.

Teaching strategy is necessary for the teaching and learning process. It is used as a way to present learning content in a way that engages the learners. It is assumed that applying appropriate teaching strategies has a positive impact on students' achievement. This study aimed to analyze students' perceptions of teacher's teaching strategy and its effect on students' achievement in learning English. This study was an Ex-post Facto study. The population of this study was the students who had studied English as a general subject at Universitas Negeri Padang in the academic year of January-June 2019. Cluster random sampling was used with 150 students as the sample of this study. Then, for collecting the data, two questionnaires and documents of students’ final scores were used as the instruments. The data was analyzed by using a Likert-type scale and regression linear statistical analysis through IBM SPSS Statistics 22 Software. The results showed that generally, students' perception of the teacher's teaching strategy was High. Then, based on the statistical analysis, it was found that thevalue of F-count was lower than F-table. It meant that the null hypothesis (H0) was accepted, and the alternative hypothesis (Ha) was rejected. Thus, there was no significant effect of student's perception of teaching strategy towards students' achievement in learning English as a general subject.

The general guidelines of Indonesian word formation as annexed in appendix II of the reference standard of the Indonesian Grammar has not yet accommodated the Indonesian word formation system used by the Indonesian speakers today. Meanwhile, a new system of word formation began to emerge and the old paradigm shift in conjunction with the development of science and technology, and the change of social, cultural, and political paradigm. As a result, the reference standard of Indonesian grammar is no longer adequate to understand the system of the formation of the new words. Morphological studies, which analyze the internal structure of the words can be used as a theoretical foundation to address the issues of the Indonesian word formation. From the other side, sociolinguistic studies, which analyze the link of language with the language speakers in the community, can give meaning to the word formation shift. This article discusses (1) the morphological shift of the Indonesian word formation system of acronyms, blending, and clipping, (2) the sociolinguistic functions of the word formation, and (3) the productivity of the word formation system. The study of the shift of word formation system revealed a shift in the way of thinking and the way of looking at social, cultural, and political problems of the Indonesian speakers nowadays.

Sementara itu, sistem pembentukan kata baru mulai bermunculan menggeser paradigma lama bersamaan dengan perkembangan ilmu pengetahuan dan teknologi, serta perubahan paradigma sosial, budaya, dan politik. Akibatnya, standar acuan tata bahasa Indonesia sudah tidak memadai lagi untuk memahami sistem pembentukan kata baru. Kajian morfologi, yang menganalisa struktur internal kata dapat dijadikan landasan teoritis untuk mengatasi permasalahan pembentukan kata bahasa Indonesia. Dari sisi lain, kajian sosiolinguistik, yang menganalisa hubungan bahasa dengan penutur bahasa di masyarakat, bisa memberi makna pada pergeseran pembentukan kata ini. Artikel ini membahas (1) pergeseran morfologis sistem pembentukan kata dalam bahasa Indonesia pada bentuk akronim, blending, dan kliping, (2) fungsi sosiolinguistik dari pembentukan kata, dan (3) produktivitas sistem pembentukan kata. Kajian tentang pergeseran sistem pembentukan kata mengungkapkan adanya pergeseran cara berpikir dan cara melihat masalah sosial, budaya, dan politik para penutur Bahasa Indonesia saat ini.Kata kunci: pembentukan kata, pergeseran bahasa, morfologi, sosiolinguistik, blending, kliping, akronim
