“…When developing metacognition, students are trained to monitor, evaluate, and control their learning process independently (Akturk & Sahin, 2011;Lai, 2011). Furthermore, enriched virtual-PjBL can significantly affect metacognitive skills because the PjBL syntax is composed of various activities that improve students' higher-order thinking skills (Pratama, Sopandi, Hidayah, & Trihatusti, 2020;Rahman, Wahyuni, & Noviani, 2018). These metacognitive skills are reflected in the PjBL syntax stages, including: (1) students ask basic questions, (2) students develop projects, (3) students plan projects, (4) students work on projects, (5) teachers monitor, ( 6) evaluation (Novianto, Masykuri, & Sukarmin, 2018;Sularmi, Utomo, & Ruja, 2018).…”
