This study investigates the effectiveness of online discussion forums, supported by smartphone applications, in enhancing critical thinking skills (CTS) among prospective teachers. Conducted as a quasi-experiment with 37 participants in a Genetics course, the research applied problem-based discussion forums to assess and improve CTS.
