The value of explicit vocabulary instruction is lost in the absence of a principled isolation of the right words to give focused attention. The key or ‘must-know’vocabulary should find expression and resonance in all languages. The present study, a precursor to an empirical study on the extent to which African languages can handle concept vocabulary in the teaching of Technology, isolates the key must-know Grade 8 Technology Education vocabulary in English. Vygotsky’s (1986) theory of scientific concept development informed the distinction between scientific and everyday concepts. Ha and Hyland’s (2017) Technicality Analysis Model (TAM) and its five levels of technicality informed the judgment-based methods that were used to determine key Technology Education vocabulary at Grade 8 level. Over and above the model, some criteria emanated from the defining characteristics, the contextual clues, as well as Chung and Nation’s (2004) four-step rating scale. The criteria applied yielded 80 key vocabulary, largely technical and substantive and bearing threshold concepts. The study recommends combining the words of the Tier 3 with the more general academic vocabulary of the Tier 2 to narrow the instructional focus and increase the conceptual understanding of the teaching of Grade 8 Technology.  \nKEYWORDS  \nConcept; technical words; technology subject; technology vocabulary; Tier 3.  \nINTRODUCTION  \nAcquisition of a sufficiently robust and relevant vocabulary is a password to textual comprehension. Understanding subject concepts and the vocabulary in which they are couched is highly correlated with textual comprehension. Rupley et al. (2012) observe that:  \nNot having access to the meaning of words representative of the concepts and content of what they read causes difficulty in children’s comprehension of texts, limits their ability to make a connection with their existing background knowledge, inhibits their ability to make coherent inferences, and impacts their ability to reason (p. 300) .  \nWhat was challenging to the researchers was determining words to prioritise to unlock textual meaning. Successful understanding of texts depends on learners’ repertoires crossing particular lexical thresholds. “Transcending vocabulary thresholds ensures reading with understanding and guarantees the derivation of meanings ofthe few unknown words from their contextual use”(Sibanda & Baxen, 2016, p. 58) . The lexical thresholds that need to be crossed for textual comprehension are as high as 98% of words in the text. The sheer volume of words learners are exposed to, and which need to be taught and understood in a discipline, makes it imperative to prioritise some words over others because “in terms of usefulness, all words are not created equal”(Nation, 2007, p. 20) . Tiering words is useful for narrowing the instructional focus because not all words can be given explicit attention.  \nIn hierarchical vocabulary tiers, high-frequency words (HFWs) constitute Tier 1 words – the basic, familia","cbCainm3e2b4APkE","https://ap.wps.com/l/cbCainm3e2b4APkE","pdf",1176570,23,"English","# ABSTRACT\n# KEYWORDS\n# INTRODUCTION\n# Literature Review","[{\"question\":\"Why is explicit vocabulary instruction important for Grade 8 Technology Education?\",\"answer\":\"Explicit instruction supports conceptual understanding because words carry domain concepts.
