Effectively designed science learning environments revolve around students' sensemaking through the use of evidence to ground explanations about natural phenomena. However, little research has been conducted to investigate elementary teachers' learning to promote students' sensemaking in elementary (K-5) classrooms. The purpose of this…

In this study, an instrument, Using Mathematics in Science Self-efficacy Scale (UMSSS), was developed in order to determine preservice science teachers' self-efficacy toward the use of mathematics in their lessons. Data gathered from 250 preservice science teachers were used for Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis…

The present study examined the validity of the Basic Empathy Scale (BES) [Jolliffe, D., & Farrington, D. P. (2006a). Development and validation of the Basic Empathy Scale. "Journal of Adolescence," 29, 589-611; Jolliffe, D., & Farrington, D. P. (2006b). Examining the relationship between low empathy and bullying. "Aggressive…

The purpose of this study was to validate the instrument, Administrator Dispositions Index (ADI), that measures the dispositions of effective school leaders.
