Science education research emphasizes the irreplaceable value of textbooks in students' acquisition of scientific knowledge. Illustrations such as diagrams contained in science books are crucial modes of visual representations that facilitate learners' conceptual learning. Through classifying, coding, and analysing diagrams from twenty science…

Researchers suggest that certain supportive behaviors of mentors could increase the benefits of school-based mentoring for youth. However, the literature contains few validated instruments to measure these behaviors. In our present study, we aimed to construct and validate a tool to measure the supportive behaviors of mentors participating in…

The purpose of this study is to analyze scientific literacy levels relevant to science and technology classes among gifted students that participate in scientific activities at science and art centers. This study investigated whether there was a significant difference in scientific literacy levels among gifted students according to the areas of…

This brief will discuss patterns of science and engineering educational attainment within the foreign-born population living in the United States, using data from the 2010 American Community Survey (ACS). The analysis is restricted to the population aged 25 and older, and the results are presented on science and engineering degree attainment by…

The underlying principles and assumptions associated with DNA histograms are discussed along with the characteristics of fluorescent probes. Information theory was described and used to calculate the information content of a DNA histogram. Two major types of DNA histogram analyses are proposed: parametric and nonparametric analysis. Three levels…

Summarizes a simple design algorithm which identifies nested loops of equations which must be solved by trial-and-error methods. The algorithm is designed to minimize such loops, provides guidance to the selection of variables, and delineates the order in which systems of equations are to be solved. Examples are included.

This codebook for a machine-readable data file contains the frequencies for the values of variables for cases that are the individual activities in the Surroundings module of the BSCS Human Sciences Program. Students rated each activity on a six-item, Likert-type scale and responded to open-ended questions about the activity. Surroundings was one…

This codebook for a machine-readable data file contains frequencies for the values of 310 variables for 446 student cases that comprised the field test data from the testing of Knowing, a Level III module of the BSCS Human Sciences Program. This module was developed and field tested with eighth-grade students in middle schools and junior high…

This codebook for a machine-readable data file contains the frequencies for the value of 23 variables for each of the 3,173 student-activity evaluation interactions (cases) for the 44 activities in the Human Sciences Knowing Module. Students rated each activity on an eight-item, Likert-type scale and responded to open-ended questions about the…

This codebook for a machine-readable data file contains frequencies for the values of 1,275 variables for 734 student cases that comprise the field-test data from the BSCS Human Sciences curriculum project. This three-year interdisciplinary science curriculum, designed for 11- to 14-year-olds, was field-tested in seven middle and junior high…

This codebook for a machine-readable data file contains eight variables that describe the characteristics of 623 activities or activity parts that comprise the activities used in the field test of the BSCS Human Sciences Program, 1973 to 1976, and 1977, in middle and junior high schools in the United States. The file also includes 52 variables…
