A system and method for characterizing, selecting, ordering and rendering discrete elements of digitized video content to teach communications and pedagogic skills. Each of a plurality of observed or computer-generated instances of modeling of distinguishable teaching skills are recorded as digitized assets. Microskills are identified and deconstructed in the abstract from one or more of the visual and audible recordings of teaching skills modeling moments. Identifiers of microskills are associated by a human editor with recorded modeling instances and/or portions thereof. Modeling presentations are dynamically generated by a user asserting one or more microskill identifiers and a network-enabled selection, ordering and rendering of portions of modeling instances that are associated with the asserted microskill identifiers.

A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

A writing instrument comprises an elongated barrel having a first end, a second end and a plurality of sides including at least three sides, each side having data printed along its length at uniform spacing increments from the first end, the data on any two sides that share the same distance from the first end are computationally related to the data on another side that shares the same distance from the first end. The data includes at least one of a numerical data or a phonic alphabet. The numerical data on a first side and a third side is linked to a sign that associated with an arrow respectively to indicate the direction to which the writing instrument should be rotated to signify the computation relation. Thus, the elongated barrel defines a triangular shaped writing instrument that allows a user to learn the computation relation between the data.

Comparative effectiveness of various oral care products such as dentifrices on preventing dental erosion may be demonstrated using simulated enamel. A substrate is prepared. A mineral layer to simulate dental enamel is nucleated by solution growth on the substrate surface. Alternatively, the mineral layer may be nucleated on a template comprising a self-assembled monolayer formed on a gold layer deposited on the substrate surface. The mineral layer may comprise a homogeneous layer of hydroxyapatite or a thin veneer of hydroxyapatite on a layer of amorphous calcium phosphate. The simulated enamel is then optionally treated with an oral care product and subjected to an acid challenge. The amount of mineral layer remaining after the acid challenge illustrates the effectiveness or non-effectiveness of the oral care product at preventing dental erosion.
