The reliability of two visual motor integration tests used with children

Occupational therapists often assess the visual motor integration (VMI) skills of children and young people. It is important that therapists use tools with strong psychometric properties. This study aims to examine the reliability of 2 VMI tests. Ninety-two children between the ages of 5 and 17 years (response rate of 31%) completed 2 VMI tests: the Developmental Test of Visual Motor Integration (DTVMI) and the Full Range Test of Visual Motor Integration (FRTVMI). Cronbach\u27s alpha coefficient was used to examine the internal consistency of the 2 VMI tests whereas Spearman\u27s rho correlation was used to evaluate the test&ndash;retest reliability, intrarater reliability, and interrater reliability of the 2 VMI tests. The Cronbach\u27s alpha coefficient for the DTVMI was .82 and .72 for the FRTVMI. The test&ndash;retest reliability coefficient was .73 (p = .000) for the DTVMI and .49 (p = .05) for the FRTVMI. The interrater correlation was significant for both the DTVMI at .94 (p = .000) and FRTVMI at .68 (p = .001). The DTVMI intrarater reliability correlation result was .90 (p = .000) and the FRTVMI at .85 (p = .000). Overall, the DTVMI exhibited a higher level of reliability than the FRTVMI. Both VMI tests appear to exhibit reasonable levels of reliability and are recommended for use with children and young people.<br /

A Valid and Reliable Instrument for Cognitive Complexity Rating Assignment of Chemistry Exam Items

The design and use of a valid and reliable instrument for the assignment of cognitive complexity ratings to chemistry exam items is described in this paper. Use of such an instrument provides a simple method to quantify the cognitive demands of chemistry exam items. Instrument validity was established in two different ways: statistically significant correlations between expert-based cognitive complexity ratings and student performance (as measured through statistical difficulty of items), and statistically significant correlations between expert-based cognitive complexity ratings and student mental effort ratings. Key benefits associated with instrument use include an enhanced understanding of the cognitive complexity of chemistry assessment tasks and as a means for characterizing exam content for the measurement of cognitive development

Curriculum matters: Creating a positive climate for diversity from the student perspective

The purpose of this paper is to identify the factors that predict students’ perceptions of their institution’s success in achieving a positive climate for diversity. This study examines a sample of 544 students at a large, public, predominantly White Mid-Western institution. Results show that students’ perceptions of the institution’s ability to achieve a positive climate for diversity is a reflection of students’ precollege interactions with diverse peers and the institution’s ability to incorporate diversity-related issues into its curriculum. Results also indicate that these perceptions differ by race and gender. Implications for institutional researchers are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43632/1/11162_2005_Article_2967.pd
