<![CDATA[This study investigated the effect of smartphones as an economics learning medium on the learning interest of Grade X students at MA Yapit Taretta. A quantitative ex post facto design was applied to 43 students selected through saturated sampling. Data were collected through observation, questionnaires, and documentation. The research instrument consisted of 20 Likert-scale statements covering smartphone use in economics learning and students’ learning interest. Data analysis included descriptive statistics, item validity, reliability, normality, simple linear regression, and a partial t-test. All questionnaire items were valid because their item-total correlations exceeded the critical value of 0.3008. The instruments were reliable, with Cronbach’s alpha coefficients of 0.782 for smartphone use and 0.756 for learning interest. The residuals were normally distributed (significance = 0.142). The regression coefficient was positive (B = 0.462), with t = 3.254 and p = 0.002. These results indicate that smartphones used as an economics learning medium have a positive and statistically significant effect on students’ learning interest. Appropriate instructional guidance is therefore required so that smartphone use supports access to learning resources, interactive activities, concentration, participation, and curiosity rather than becoming a source of distraction.]]>
