Abstract

This study is an autobiography of the author's experience as an English teacher teaching 12th graders digital multimodal composing (DMC). I have been teaching vocational high school students for seventeen years in one of Indonesia's vocational high schools. I am still looking for the best way to develop the writing skills of vocational high school students. I want to alter their perceptions of writing. It is essential to create a fun and meaningful writing process both inside and outside the classroom. Students born in the twenty-first century, the digital generation, and modern students. DMC as the textual practice entails using digital tools to generate text by combining various semiotic modes. Each mode is meaningful and serves a purpose. As a teacher, I can create any digital mode based on my students' needs and knowledge. This study used the narrative inquiry method to explore and reflect on the story of the teacher.

Abstract

Background: Language development is a crucial aspect of a child's growth and development, influenced by various factors, including environmental stimulation. One emerging factor receiving significant attention is excessive digital media use, or screen time. Uncontrolled screen time can lead to developmental problems, including speech delays in children. Most parents remain unaware of appropriate screen time limits and their impact on children's language development, highlighting the need for effective educational interventions. Objective: This study aimed to increase the knowledge of family members of pediatric patients at Haji General Hospital, East Java Province, regarding the relationship between screen time and speech delays. Methods: The method used was descriptive-analytical, with educational delivery using PowerPoint presentations and leaflets, as well as formative evaluation activities in the form of pretests and posttests. These were then analyzed using a paired-group pretest-posttest design using SPSS. Results: The paired t-test analysis comparing pretest and posttest scores showed a statistically significant difference (p = 0.045), indicating an increase in family knowledge regarding the relationship between screen time and speech delays.
