Abstract: Modern research in the science of reading has shed light on how the human brain learns to read and write. Scientists now understand reading is not based on visual memory, but a process of orthographic mapping where students connect the sounds and meaning of a word to the sequence of letters that spell the word. A teaching tool is presented that utilizes phoneme and grapheme manipulatives designed to be arranged by students to build words in a word building area. Instructional grid lines promote orthographic mapping, aiding the development of student's understanding of phoneme-grapheme correspondence. A durable, zippable enclosure allows for portability and safe keeping. A storage compartment for grapheme manipulatives that have not been introduced yet, along with a phoneme and grapheme presentation areas help students stay organized without being overwhelmed. Gradually introducing new graphemes promotes the systematic and cumulative practice recommended by modern research in literacy.

Abstract: Devices, systems, and methods that facilitate learning a language in an extended reality (XR) environment.

Abstract: Described herein are examples of weld training systems that show (e.g., transparent and/or translucent) “ghost” images of a welding tool on a display screen of a welding headgear to indicate target positions and/or target orientations of an actual welding tool. In some examples, the weld training systems may additionally “reset” the target tool image to a position closer to the actual welding tool if the target tool image gets too far away. The ability to “reset” the target tool image to a position closer to the actual welding tool may help in minimizing a risk that an operator 106 will overcompensate to try to catch up with the target tool image, which can be detrimental to the weld. Additionally, resetting the target tool image to a position closer the welding tool may allow an operator to better perceive and/or understand differences in orientation and/or other technique parameters.
