The current study investigated the development of global and domain (academic, physical, same-sex peer relationship, opposite-sex peer relationship) self-esteem from age 10 to 16 in a sample of Mexican-origin adolescents. Participants' (N = 674) responses on the Self-Description Questionnaire (SDQ; Marsh, 2005) II-S showed moderate rank-order…

This research was carried out to reveal the bioethical values that special, talented students have about the socioscientific issues that they may encounter in everyday life. Scanning model was used in the research from quantitative research methods. The study's working group is composed of special talented fifth, sixth, seventh, eighth, ninth, and…

In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

This research examined the process and conditions of social projection of biased ethnic attitudes to classmates in two samples of Grades 4-6 children (n = 342, M[subscript age] = 10.75, SD = 0.98; 49% girls; and n = 525, M[subscript age] = 10.49 years, SD = 0.96; 51% girls). Children reported on the ethnic group norm in their classroom and on…

The problem investigated in this quantitative study was that schools in a small, rural East Texas town were falling below acceptable ratings in reading on the Texas Assessment of Knowledge and Skills (TAKS) and the State of Texas Assessment of Academic Readiness (STAAR). Researchers have found that constructive-based learning environments (CBLEs)…

The purpose of this study was to investigate the relationship between teacher efficacy levels and fifth grade Virginia SOL Mathematic achievement. This study sought to determine the extent to which personal efficacy, general efficacy, and total efficacy account for fifth grade Virginia Standards of Learning Mathematic achievement over and above…

Background: We examined longitudinal changes in children's physical activity during the school day, afterschool, and evening across fifth, sixth, and seventh grades. Methods: The analytical sample included children who had valid accelerometer data in fifth grade and at least one other time-point, and provided complete sociodemographic information…

Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and…

The benefits of outdoor education are well known and irreplaceable. Teachers of environmental lessons frequently ask themselves what kind of cartographic support (paper maps or mobile navigators) to offer their students doing fieldwork either navigating to selected points or being engaged in the research of a selected environment. In this article,…

This study adopted a quasi-experimental design with follow-up interview to develop a computer-based two-tier assessment (CBA) regarding the science topic of electric circuits and to evaluate the diagnostic power of the assessment. Three assessment formats (i.e., paper-and-pencil, static computer-based, and dynamic computer-based tests) using…

The purpose of this study is to prepare a multiple-choice achievement test with high reliability and validity for the "Let's Solve the Puzzle of Our Body" unit.
