Despite an increasing focus on integrating engineering design in K-12 settings, relatively few studies have investigated how to support students to engage in systematic processes to optimize the designs of their solutions. Emerging learning technologies such as computational models and simulations enable rapid feedback to learners about their…

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students' learning from the teachers' perspectives. Only a limited number of studies have investigated the components of…

This study examined the impact of computer simulation and supported science learning on a teacher's understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers' concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting…

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high…
