摘要： Along with traditional academic knowledge, 21st-century skills are crucial for equipping students with a competitive future. Project-based learning (PBL) cultivates these competencies among learners as an instructional approach. This research aimed to construct and analyze a PBL framework designed to weave 21st-century skills into high school education. Data collection involved a survey questionnaire based on an extensive literature review administered to students from ten government-run girls' high schools, where mathematics was taught using the PBL approach. Employing Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) via the Analysis of Moment Structures (AMOS) software, the study meticulously calculated chi-square values, modification indices, and standardized estimates to validate the framework's effectiveness. The results showed a significant enhancement in collaborative learning, problem-solving, critical thinking, and positive attitudes toward mathematics among students, mediated by the PBL approach. The Heterotrait-Monotrait Ratio (HTMT) values were below the threshold of 1, confirming discriminant validity and ensuring that each construct was unique. The observed substantial correlations between PBL and educational outcomes, ranging from moderate to significant, attest to these variables' interconnectedness and mutual reinforcement. Overall, the structural model and subsequent analyses underscore PBL's pivotal role in promoting active learning and student engagement. This approach advocates its adoption as a forward-thinking educational strategy. © 2024 The Authors

摘要： The acquisition of hysteresis-free and large electrostrain in lead-free piezoelectric thin films is the key issue for the development of high-performance micro actuators. The electrostrictive effect is an appropriate choice for developing hysteresis-free electrostrain. Lead-free ferroelectric compound Bi1/2Na1/2TiO3 has great potential in realizing large electrostrain response and electrostrictive coefficient. In this work, (0.8-x)Bi1/2Na1/2TiO3-0.2SrTiO(3)-xBaTiO(3) (BNT-ST-100xBT) thin films were prepared by chemical solution deposition method. The crystal structure, morphology, dielectric properties, electrostrictive effect, dielectric nonlinearity, ferroelectric properties, and electrostrain response were systematically investigated. The most significant electrostrictive effect was obtained in the ergodic relaxor BNT-ST-6BT thin film, i.e., a giant electrostrictive coefficient of 0.21 m(4)/C-2. Meanwhile, by increasing the applied electric field, a linearly increasing strain and the maximum value of 0.82 % were obtained in this film. This work has made an important step in the electrostrictive effect study and provides a pathway to obtain hysteresis-free electrostrain in lead-free perovskite ferroelectric thin films.
