Broad exploration is often the best way to solve complex problems because the best solution might not come to mind first. Consequently, creative thinking, like simulated annealing, begins with a "hot" exploratory phase of broad solution search and gradually "cools" to exploitation and narrowing the search space. In solving…

Research has established the importance of play-based experiences for young children's development and learning. Yet, facing the mounting pressure of accountability and standardized testing, some educators have turned to didactic methods of instruction. Guided play (Weisberg et al., 2016) provides a middle ground between play and instruction for…

Executive function (EF) predicts children's academic achievement; however, less is known about the relation between EF and the actual learning process. Furthermore, more research is needed to better understand how different aspects of the learning environment interact with EF to influence learning. The current dissertation includes two studies to…

This study investigated the effects of two instructional approaches -- Discovery Learning Scientific Community Laboratories (DL-SCL; Treatment) and non-DLSCL laboratories (Control) -- on students' conceptual understanding, epistemological views, and academic achievement in a Physics-1 lab. Conceptual understanding was measured pre/post using the…

Through a non-experimental descriptive and comparative mixed-methods approach, this study investigated the experiences of sixth grade earth science students with groundwater physical models through an extended SE learning cycle format. The data collection was based on a series of quantitative and qualitative research tools intended to investigate…
