This study designed a science course following collaborative problem solving (CPS) processes, and examined the effect on students' CPS awareness. The "Limnic Eruption" CPS course was implemented using a Moodle system in a tenth-grade class. Considering the complex and coordinated nature of CPS, in order to improve CPS skills, it is…

The aim of this study was to analyse the effect of the visiting-scientist approach supported by conceptual change activities on high school students' images of scientists and perceptions of gender and risks that scientists take. Twenty-five students attending 10th grade in the 2017-2018 academic years participated in the study. A…

The goal of the present study was to investigate the effect of short Arabic vowels on listening comprehension. It is well documented that short vowels affect reading and reading comprehension in Arabic literacy. Since reading comprehension and listening comprehension share many commonalities, it is assumed that short vowels will positively affect…

This study investigated U.S. ethnic majority and minority youth's perceptions of fair and unfair treatment by authorities and evaluations of three situations of interracial exclusion (N = 685). Findings revealed that older adolescents who reported fair treatment by authorities were more likely to perceive wrongfulness in interracial exclusion…

This paper describes the development of different lesson plans dealing with authentic and controversial socio-scientific issues in the framework of climate change. These lesson plans orient themselves along the socio-critical, problem-oriented approach to science teaching. They deal with the use of bioethanol as an alternative fuel and with the…

This study examined classroom climate and student goal structures in high-school biology classrooms in Kenya. Participants included 891 students and their teachers in Grades 10 and 11 from two same-sex boarding schools--one for boys and the other for girls. School differences were found on all classroom climate aspects except teacher support and…

Although there have been numerous scientists-in-the-classroom initiatives in recent years, there is little research that documents whether or not these initiatives make an impact on students. This study examined 27 seventh-grade and 27 tenth-grade students' perceptions of scientists before and after a weeklong educational experience on…

This study describes high school students' conceptual development of the basic astronomical phenomena during real-time interactions with a Virtual Solar System (VSS). The VSS is a non-immersive virtual environment which has a dynamic frame of reference that can be altered by the user. Ten 10th grade students were given tasks containing a set of…
