Evaluation for 4.D.3b
Materials include explicit (direct) instruction on morphological skills in alignment with grade-level TEKS as appropriate for the program's stated purpose.
The materials provide explicit instruction in morphology through the use of affix and base cards, educator modeling, and guided word-building activities. Students identify base words and affixes, discuss how affixes change word meanings, and apply newly formed words in sentences. The
Instructional Strategies Guide also provides guidance for immediate corrective feedback during instruction. For example, in the Base Camp lesson “Picnic at Sunset,” the “Phonics” section provides explicit instruction on prefixes. Educators are directed to “Display the Affix Card
un- and the Letter Cards to build
zip. Say:
un- is a prefix. A prefix is a word part that comes at the beginning and changes the meaning of the base word. The prefix
un- means ‘not.’
Zip is a base word and a closed syllable.” Educators model reading
un- and
zip separately before blending the word
unzip. Students then discuss the meaning of each word part, explain how the prefix changes the meaning of the base word, and use
unzip in a sentence. The lesson extends instruction by repeating this routine with the prefixes
non- (“not”),
mis- (“wrong”), and
trans- (“across”) using the words
nonstop,
misspell, and
transmit.
Another example appears in the Base Camp lesson “The Cat Bath,” where educators provide explicit instruction on the inflectional endings -
s and -
es. Educators use letter cards and affix cards to build the words
sits,
tells, and
washes, and they guide students to identify the base word and ending in each word. Educators explain that the endings -
s and -
es can indicate present-tense action and model additional examples, such as
cats and
dishes, to demonstrate how these endings can also indicate plural nouns. Students identify the base word and ending in each example, discuss the meaning of the inflected forms, and respond to educator questions about when to use -
s or -
es.
