A large body of work has shown that science teacher knowledge is one of the most fundamental components of effective teaching and learning. Our study analyzes the Praxis® Earth and Space Science Content Knowledge Test (ESS CKT) from May 2006 to June 2016. We present one of the largest datasets comprising 11,273 ESS teacher candidates in order to…

In the decade since the 2007 "JGE" special issue on broadening participation, much work has been done to draw new voices into the geosciences, and the number of students from underrepresented groups graduating with geoscience degrees has grown. However, the rate of increase is not yet large enough that geoscience demographics represent…

What teachers know about their content area plays a role in how they effectively enhance the scientific literacy of their students. This leads to questions about teacher content knowledge as they enter the field. The Praxis Earth and Space Science: Content Knowledge Test is the most widely used licensure assessment for aspiring Earth science…

Results from a national needs assessment survey advertised through science teacher networks with the title "Polar Education--Teacher Input Needed" showed that the majority (90%) of teachers that responded are teaching about polar topics or polar regions. We received 508 responses from elementary to post-secondary teachers across the…

The teaching of Earth Sciences (ES) is particularly delicate and seems to be problematic for both learners and Moroccan teachers for multiple reasons. Based on this observation, this study aims at identifying the difficulties related to the teaching of ES by exploring the points of view of the Moroccan teachers toward this field. As an…

A great amount of research has been carried out world-wide to promote history of science as a powerful science teaching tool. Because the ways of choosing and using historical elements depend on teachers' or researchers' educational purpose, any attempt to support a single model-to-use seems difficult and probably irrelevant. However,…

Despite significant pressure to reform science teaching and learning in K12 schools, and a concurrent call to reform undergraduate courses, higher education science content courses have remained relatively static. Higher education science faculty have few opportunities to explore research on how people learn, examine state or national science…

The revised National Curriculum for Science for key stages 3 and 4 (ages 11-16) in England provides the opportunity to develop a new coherent approach to teaching about the carbon cycle, the use of carbon as a fuel and the resulting issues. The Earth Science Education Unit (ESEU) intends to develop a new workshop to support the teaching of this…

This study assessed Zambian Junior High School pre-service science teachers' understanding of the particulate nature of matter. A sample comprised 30 pre-service science teachers at a teacher training college. Data was collected through a questionnaire adopted from Ozmen and Kenan (2007). Results show that most teachers had correct views on the…

This paper reviews Ghana's performance in the TIMSS 2011 survey in comparison with other African and some high performing countries which participated in the TIMSS assessment. Students' achievement in the science content areas assessed were summarized and teacher preparation constructs of teachers of the students who took part in the assessment…

In this article, the students teachers' opinions, including rock formation and improper terms related to or different from these ideas, all of which are considered or must be considered in geology classes, have been analyzed. Alternative conception is used to inform our understanding of students teachers' ideas and describe any conceptual…

Analyzes narrative essays--stories of rock formation--written by pre-service elementary school teachers. Reports startling misconceptions among preservice teachers on pebbles that grow, human involvement in rock formation, and sedimentary rocks forming as puddles as dry up, even though these students had completed a college level course on Earth…

Describes a study of preservice elementary teachers' (n=179) perceptions of geologic time. Finds that the respondents perceived events in Earth's geological past as falling into three distinct clusters: extremely ancient, less ancient, and geologically recent. Finds also that the teachers' grasp of relative time is more secure than their grasp of…

Reports on a one semester course, "Earth Systems Science for Educators" designed to use an active learning approach to improve student knowledge of basic Earth science concepts. Reports that, based on pre- and post-course assessments of 108 elementary and middle-level education majors who took the class from 1998 to 2000, there was an average…

This paper examines the development of science content knowledge of elementary teachers (N=25) as a result of participating in a summer science Institute funded by the Massachusetts Department of Education and the National Science Foundation. The institute was designed to integrate the physical, life, and earth sciences by addressing the National…
