Four of the eight Engineering Standards in the Next Generation Science Standards (NGSS, 2013) focus on authentic science communication: "asking questions (science) and defining problems (engineering), analyzing and interpreting data, constructing explanations (for science) and designing solutions (for engineering), engaging in argument from…

Purpose: The purpose of this journal-ready dissertation was to examine the extent to which differences were present in discipline consequence assignments by the ethnicity/race and economic status for Grade 6, 7, and 8 girls in Texas. In the first investigation, the degree to which discipline consequence assignments differed by the ethnicity/race…

Self-reports of grade at first menstrual period for 1,967 fourth-grade through ninth-grade girls were used to categorize girls as early maturers. The categories of early maturer and other (on-time or late maturers) were then examined for stability over a 3-year period using McNemar tests and [kappa] coefficients. Although the results showed…
