In this chapter, we present illustrations of second grade students' reasoning about patterns and two-part function rules in the context of an early algebra research project that we have been conducting in elementary schools in Toronto and New York City . While the study of patterns is mandated ...

Each transducer on the device can be biased with a voltage of an arbitrary phase. The relative offset of these individual phase delays creates patterns of constructive/destructive interference. This allows the FlexArray to steer the ultrasound beam in specific directions in three dimensions at an ar...
If significant differences were found, we performed as post- hoc analysis with Wilcoxon signed rank tests to uncover in- teresting patterns. In our post-hoc analysis, we controlled the Figure 9. Software tools ranked from worst to best by participants. chance of Type I errors by using a ...
This chapter addresses children’s geometry thinking and learning in early childhood with a focus on the use of gestures. The chapter begins with the theoretical frameworks which underlie this work and some background information about geometry learning
r–s Fabry-Perot patterns in guided power spectra for NW WGs with length of 21 μm (r, WG1) and 53 μm (s, WG2) Full size image Extinction spectra were collected from both GSL and WG segments of NWs with three distinct geometric parameters (Fig. 4i–n) designed to tune the...
only the pattern simulated based on equal population in the two sites matches well with the features of the experimental patterns. Thus, in the simulation, we assumed the same energy state of the two sites and in turn equal population of the two sites. In most of the2H patterns in Fig.6a...
