Student Academic Vocabulary Word Meaning (SAVM)

SAVM will measure change in student vocabulary knowledge (multiple choice test of meaning). The multiple choice test is based on the assessment used in Beck et al. (1982) and McKeown et al. (1983) with middle school students. Scores were computed as the total percentage of vocabulary words correctly identified out of 72. Score could range from 0 to 100 and higher scores indicate greater levels of vocabulary knowledge.

Parent Academic Vocabulary Word Meaning (PAVM)

PAVM will measure change in parent vocabulary knowledge (multiple choice test of meaning). The multiple choice test is based on the assessment used in Beck et al. (1982) and McKeown et al. (1983) with middle school students. Scores were computed as the total percentage of vocabulary words correctly identified out of 72. Score could range from 0 to 100 and higher scores indicate greater levels of vocabulary knowledge.

Student Academic Vocabulary Word Usage (SAVWU)

SAVWU will measure change in student ability to correctly use vocabulary words in sentence contexts. The sentence verification test is similar to the Test of Instructed Word Knowledge in Vocabulary used in the Apthorp et al. (2012) study of vocabulary learning in middle school. Scores were computed as the total percentage of vocabulary words correctly used in sentence context out of 72 items. Score could range from 0 to 100, and higher scores indicate greater levels of vocabulary words used correctly in a sentence.

Parent Academic Vocabulary Word Usage (PAVWU)

PAVWU will measure change in parent ability to correctly use vocabulary words in sentence contexts. The sentence verification test is similar to the Test of Instructed Word Knowledge in Vocabulary used in the Apthorp et al. (2012) study of vocabulary learning in middle school. Scores were computed as the total percentage of vocabulary words correctly used in sentence context out of 72 items. Score could range from 0 to 100 and higher scores indicate greater levels of vocabulary words used correctly in a sentence.

Student Academic Vocabulary Usage Behaviors (SAVUB)

SAVUB will measure change in student use of SAV words (10 items). Items were adapted from: the Student Engagement Instrument (SEI; Betts, Appleton, Reschly, et al., 2010). Items used a 4-point response option (1 = not at all, 4 = 3-4 times per week) and a mean score and could range from 1 to 4. Higher scores indicated greater use of SAV words.

Parent Academic Vocabulary Usage Behaviors (SAVUB)

SAVUB will measure change in parent use of SAV words (10 items). Items were adapted from: the Student Engagement Instrument (SEI; Betts, Appleton, Reschly, et al., 2010). Items used a 4-point response option (1 = not at all, 4 = 3-4 times per week) and a mean score and could range from 1 to 4. Higher scores indicated greater use of SAV words.

Student Confidence in using AV words (SCAV)

SCAV will measure student confidence in using SAV words (10 items). Items were adapted from the Efficacy to Influence School-related Performance subscale of the Parental Self-Efficacy Scale (PSES; Bandura, et al., 2001). Items were developed using procedures for developing self-efficacy scales (Bandura et al., 2001). Items used a 5-point response option (1 = not at all confident, 5 = extremely confident) and a mean score was computed and could range from 1 to 5. Higher scores indicated greater confidence using SAV words.

Parent Confidence in using AV words (PCAV)

PCAV will measure parent confidence in using SAV words (10 items). Items were adapted from the Efficacy to Influence School-related Performance subscale of the Parental Self-Efficacy Scale (PSES; Bandura, et al., 2001). Items were developed using procedures for developing self-efficacy scales (Bandura et al., 2001). Items used a 5-point response option (1 = not at all confident, 5 = extremely confident) and a mean score was computed (alpha = .95) and could range from 1 to 5. Higher scores indicated greater confidence using SAV words.
