Reinforcing contingencies for sex-role behaviors in preschool children

Two groups of disadvantaged Afro-American children, a total of 30 boys and 25 girls, mean age about 42 months; and two groups of middle- and upper-middle-class children, most of them white, 35 boys and 31 girls, mean age about 44.5 months, were observed for patterns of sex-role-characteristic behavior and peer and teacher response to such behavior. At all times, the children in the two experimental groups were being taught by seven women and seven or eight men, about half of whom were Afro-American, half white-Anglo, and who were mixed in the two schools by race but evenly divided by sex. Boys engaged in 16% sex-characteristic behavior, 5.7% cross-sex behavior. The same figures for girls were 18 and 6%. There were no pattern or percentage differences by race or social status of children. Women teachers gave most of their sex-role connected rewards for feminine behavior to both boys and girls. Men teachers rewarded more equably, masculine behaviors for boys, feminine behaviors for girls. Children rewarded mainly their own sex, and gave rewards for sex characteristic behavior. The pattern was even clearer for boys than for girls. In Discussion, comparisons are made with other somewhat similar studies.     

Participation in online discussion environments: Is it really effective?

This study aimed to develop a rubric to assess participation of students in online discussion environments. For this purpose, the study included 168 students who participated in a course offered online during the spring semester of the 2015–2016 academic year. Developed based on the literature, the rubric consists of two parts (Form and Content, and Number and Density) and seven criteria in total. “Form and Content” consists of congruity of the message in terms of subject, clarity of the message, original value of the message, interactional value of the message, and directing the subject; whereas, “Number and Density” consists of the number of messages and their density. Four different discussion subjects were presented to the students in an online discussion environment. The researchers analyzed the students’ messages individually. Exploratory Factor Analysis was performed in order to obtain evidence for construct validity. After conducting the factor analysis, results showed that the first dimension, which is “form and content” sub-factor, is unidimensional. The “number and density” sub-factor was included in the graded scoring key based on the literature and expert opinion. The findings show that the graded scoring key is reliable and valid.
