Blog Entry: Exploring the Association Between Screen Time and Academic PerformanceDataset Choice:For this assignment, I have chosen to work with a hypothetical "Youth Health and Education Survey" (YOUTHES) dataset. This dataset is designed to capture various aspects of adolescent life, including health behaviors, academic engagement, and social factors.Research Question and Proposed Association:I am interested in exploring the association between screen time and academic performance among adolescents. Specifically, I want to investigate whether increased daily screen time (measured in hours) is associated with lower academic performance (measured by GPA or self-reported grades).Personal Codebook (YOUTHES Dataset - Excerpt)Below is a section of my personal codebook, focusing on the variables relevant to my chosen topics.Topic 1: Screen Time| Variable Name | Description | Response Options/Coding ||---|---|---|| SCREEN_DAILY_HRS | Average daily hours spent on screens (e.g., phone, computer, tablet, TV) for non-academic purposes. | Numeric (e.g., 0-10+ hours) || SCREEN_LEISURE | Hours spent on screens specifically for leisure activities (e.g., gaming, social media, streaming). | Numeric (e.g., 0-10+ hours) || DEVICE_OWNERSHIP | Does the respondent own a personal smartphone/tablet? | 1 = Yes, 0 = No |Topic 2: Academic Performance| Variable Name | Description | Response Options/Coding ||---|---|---|| GPA_CURRENT | Current self-reported Grade Point Average. | Numeric (e.g., 0.0 - 4.0 scale) || REPORT_GRADES | Self-reported typical grades in core subjects (e.g., Math, English). | 1 = Mostly A's, 2 = Mostly B's, 3 = Mostly C's, 4 = Mostly D's, 5 = Failing || HOMEWORK_HRS_WEEK | Average hours spent on homework per week. | Numeric (e.g., 0-20+ hours) |Literature ReviewSearch Terms Used:My literature review focused on terms such as "screen time academic performance," "digital media use grades adolescents," "social media impact student achievement," "smartphone use education," and "leisure screen time academic outcomes."References Used (Examples - you would include full bibliographic information for your actual references): * Reference 1: A study by Przybylski, A. K., & Weinstein, N. (2017). A large-scale test of the goldilocks hypothesis: Quantifying the relationship between digital-screen use and the mental well-being of adolescents. Psychological Science, 28(2), 204-215. (While not directly about academics, this explores optimal digital use and provides a foundational understanding). * Reference 2: A meta-analysis or systematic review on screen time and academic outcomes (e.g., typically found in journals like Computers & Education or Journal of School Health). For example, a hypothetical study by Smith, J., & Jones, A. (2020). The pervasive influence: A meta-analysis of screen time and academic achievement in adolescents. Journal of Adolescent Research, XX(X), XXX-XXX. * Reference 3: A qualitative study exploring student perceptions of screen time and its effect on their study habits (e.g., from Qualitative Health Research or Youth & Society). For example, a hypothetical study by Chen, L. (2021). "It's a distraction": Adolescent narratives on smartphone use and academic focus. Youth & Society, XX(X), XXX-XXX.Summary of Findings:The existing literature generally suggests a complex relationship between screen time and academic performance, often finding a negative association, especially when screen time is excessive and unsupervised. * Variables Considered: Studies frequently examine various facets of screen time, including total daily hours, specific types of screen use (e.g., social media, gaming, passive viewing), and the context of use (e.g., during homework, before bed). Academic performance is typically measured through GPA, standardized test scores, self-reported grades, or teacher assessments. Confounding variables like socio-economic status, parental involvement, sleep patterns, and physical activity are often controlled for in more robust studies. *
