... magnet would pick up more paper clips and whether a smaller or a larger magnet would pick up more paper clips. Both the predictions and explanations were recorded before the students tested their predictions. The results of the investigation supported Andersson's suggested general constructs: 53...

.... For example, if a student is curious about self-driving cars, he/she can search for the keyword self-driving technology and find many video clips explaining the principles of self-driving control, current status of self-driving cars, and even how to make a self-driving unit using microprocessor units...

... (observing, comparing, classifying, and ordering) are usually tested by presenting students with sets of objects (toys or everyday objects such as paper clips, bottle caps, etc.) or printed photographs or drawings of various everyday objects (items from advertising brochures, toys, stamps, banknotes or coins...

... on a definition for the term “is radioactive” to be “objects in the vicinity of which a Geiger counter starts ticking.” To that end, the teacher brings in various objects like a newspaper clipping on radioactivity, a radioactive stone, etc., and asks students to agree on which objects have something to do...

... of our literature synthesis, such as static, non-digital drawings on paper/whiteboards (e.g., Wenning, 2005 ) or non-interactive simulations and video clips of physical phenomena (as can be used during lectures, for instance; see Wieman et al., 2010 ). External visualizations and their role...

...—how they feel ( Jaber and Hammer, 2016 ), their sense of self-efficacy ( Sawtelle et al., 2012 ), and their “mindset” ( Little et al., 2019 ). Here, we focus on what PER has attributed to individuals with respect to knowledge of physical phenomena. At this point in the clip, Leo...

... the traditional electricity demand in various ways. A visual presentation of different types of adjusted load shapes is presented in Fig. 8.1 . Peak load clipping: A DR type that aims at decreasing consumer usage in peak times can be classified as peak load clipping. Load shifting: Load shifting is mainly...

... on m₁ is needed. Devise an experiment to determine a numerical value for that frictional force. For convenience, there are several small masses (and paper clips for hangers) available in the laboratory. Recall that the frictional force will be equivalent to the force required to maintain a constant...

... uncertainties. Unless the students have been trained to work with uncertainties, they may need some support to consider these investigations, but they may spontaneously suggest to use a video clip to study the motion in more detail back in the classroom. The experiments in this section have been selected...

... are clipped by blackbody radiation considerations, and which often dip near line center, due to absorption in the cooler regions near the tube walls. With high enough pressure, and with the discharge temperature extending uniformly most of the way to the walls, the top of the spectral line would grow broader...

... shots from a video clip taken during the ride. (Video and data credit: Stefan Jaitner.) Giant pendulum rides Figure 7.11 illustrates the forces on a rider in a “Screamin’ Swing” where the riders are seated L = 20 m from the axis and swing up to about 115°. A chain on a playground swing...
