The alpha and split-half reliability of the teacher stress inventory

The internal consistency and split-half reliability of the Teacher Stress Inventory (TSI) was investigated based on data provided by 3,478 teachers, representing 22 individual and two aggregate samples from six states. The data indicate for both the strength and frequency dimensions that the TSI is highly reliable in terms of both its regular and short-form length, and that the two short forms are highly correlated with one another.     

Correlations between the stanford-binet: Fourth edition and the WISC-R with a learning disabled population

The Fourth Edition of the Stanford-Binet and the WISC-R were compared as instruments for assessing the intellectual strengths and weaknesses of students classified as learning disabled in the primary and secondary grades. Results found only a 3.28-point difference (p≥.0001) between the S-B Composite score and the WISC-R Full Scale score. Correlations between the four broad areas of the S-B and the three scales of the WISC-R ranged from .494 (S-B Abstract/Visual Reasoning with WISC-R Verbal) to .920 (S-B Composite with WISC-R Full Scale). All correlations were found to be significant. Implications of the research findings were discussed.     

Alternate-forms and alpha reliability of the Teacher Stress Inventory

The alternate-forms and alpha reliabilities of the Teacher Stress Inventory were investigated based on the responses of two groups of 138 teachers. Reliability estimates ranged from .43 to .94 for the TSI subscales and .71 to .94 for the TSI whole scale, indicating high stability and equivalence for the stress factors across immediate, one-day, one-week, and two-week intervals using two different TSI short forms. Between-forms correlations were larger for the immediate sample than they were for the interval samples. Short-form TSI alphas ranged from .76 to .90.     

Student achievement and differential reinforcement of incompatible behavior: Hand raising

Workbook reading achievement of five second-grade girls was assessed under two teacher-contact contingencies. Under one contingency, teacher contacts were made during on-task behavior. Under the other contingency, differential reinforcement of an incompatible behavior (DRI) was in effect, with teacher contacts contingent on students' hand-raising behavior. Both reading achievement and time on task were greater under the on-task contingency than under DRI for hand raising.     

Persistence to Graduation among At‐Risk Criminal Justice and Criminology Students: Experiences in Intervening with a Sophomore Cohort∗

A Seminar targeting academically at‐risk sophomores was developed and introduced in 2002 to address weak connectedness to the university and poor academic abilities. We measured changes in approaches taken to college studies by those at‐risk sophomores who enrolled in the course, as well as employed a longitudinal, quasi‐experimental design to track this experimental group (n = 29) and the remainder of the at‐risk cohort as a comparison group (n = 36). Our preliminary findings suggest that the Seminar has had a variety of positive outcomes, the most impressive impact being that the experimental group had dramatically better retention and graduation rates than the comparison group.
