What do classroom teachers of varying backgrounds know about English spelling?

The ability to encode (spell) is an integral writing skill needed to communicate effectively. The ability to spell, also, enhances decoding as spelling and decoding are reciprocal skills that rely on knowledge of the same subskills. Spelling can also be particularly difficult for students with literacy and phonological-processing difficulties such as dyslexia.

English Spelling Performance in Writing Samples Among Spanish-Speaking ELLs.

The depth of the English orthography makes reading and spelling in English a difficult task; particularly for English language learners (ELLs) whose first language (L1) has a shallow orthography. Mastering spelling in English is a critical component of increasing the English literacy of ELLs. This study investigated the English spelling of 569 Spanish-speaking ELLs in Grades 4 to 6.

Antibacterial properties of copper iodide-doped glass ionomer-based materials and effect of copper iodide nanoparticles on collagen degradation.

Objectives: This study investigated the antibacterial properties and micro-hardness of polyacrylic acid (PAA)-coated copper iodide (CuI) nanoparticles incorporated into glass ionomer-based materials, and the effect of PAA-CuI on collagen degradation.

Materials And Methods: PAA-CuI nanoparticles were incorporated into glass ionomer (GI), Ionofil Molar AC, and resin-modified glass ionomer (RMGI), Vitrebond, at 0.263 wt%.
