Well-designed digital games hold promise as effective learning environments. However, designing games that support both learning and engagement without disrupting flow is quite tricky. In addition to including various game design features (e.g., interactive problem solving, adaptive challenges, and player control of gameplay) to engage players,…

Feature engineering, the construction of contextual and relevant features from system log data, is a crucial component of developing robust and interpretable models in educational data mining contexts. The practice of feature engineering depends on domain experts and system developers working in tandem in order to creatively identify actions and…

In 2018 the Gulf coast of Florida suffered extensive damage from harmful algal blooms (HABs), from as far north as Clearwater Beach south to Naples. The bloom lasted nearly a year, picking up in intensity during the late summer months. HABs occur when conditions such as reduced salinity, higher water temperatures, light saturation, and currents…

The ubiquity of mobile devices makes them well suited for field-based learning experiences that require students to gather data as part of the process of developing scientific inquiry practices. The usefulness of these devices, however, is strongly influenced by the nature of the applications students use to collect data in the field. To…

Annually, ACT provides a snapshot of the college and career readiness of ACT-tested high school graduates. This report is offered as a service to inform policymakers and practitioners about selected indicators of effectiveness and how that translates into readiness. It is designed to stimulate discussion, inquiry, and action. This report is…

THE MAJOR CONCEPT OF THE UNIT IS THAT SOMETHING MUST BE DONE TO PARTICLES IN ORDER TO STUDY THEM. ATOMS ARE COMPOSED OF TWO KINDS OF CHARGED PARTICLES--PROTONS AND ELECTRONS. ANY DIFFERENCE IN THEIR NUMBERS RESULTS IN A CHARGED BODY. IF ENOUGH CHARGED BODIES ARE PRODUCED, THEY WILL AFFECT CHARGE DETECTORS. CONCLUSIONS CAN BE DRAWN FROM THE…

THE USE OF DATA SHEETS IS ENCOURAGED IN THE UNITS ON CLASSIFICATION. EACH STUDENT IS INSTRUCTED TO CLASSIFY TYPES OF LEAVES ACCORDING TO THEIR SIMILARITIES AND DISSIMILARITIES, AND THEN TO EXCHANGE LEAVES WITH ANOTHER STUDENT IN ORDER TO NOTICE IF INFORMATION ON A NEW SET OF LEAVES WOULD FIT ON THE SAME DATA SHEET. PLANTS ARE NEXT TO BE CLASSIFIED…
