A comparative review of the research literature regarding the effectiveness of continuing professional development (CPD) demonstrates that a range of different factors needs to be present if it is to have impact in the classroom and that short CPD episodes are unlikely to be effective. The Earth Science Education Unit approach to CPD had to be…

In this article, we provide three examples of the use of socioscientific issues (SSI) in a 5th-grade classroom. Taken from Earth science (beach sand replacement), life science (the Canadian seal hunt), and physical science (speed limits), the examples show how teachers can embed scientific content in controversial social issues that engage younger…

Humans have long wondered about life in the universe. Are we alone? Is Earth unique? What is it that makes our planet a habitable one, and are there others like Earth? NASA's Kepler Mission seeks the answers to these questions. Kepler is a space-based, specially designed 0.95 m aperture telescope. Launching in 2009, Kepler is NASA's first mission…

Describes major volcanic activity throughout the world in 1976. (MLH)

This paper begins with a discussion regarding the nature and complexity of understanding in the conceptually confined domain of earth science, here limited to its "geological" aspects. There then follows a report on a study of how the ideas about a range of concepts relating to the Earths structure and processes held by individual…

A simple mixing of a hot- and cold-water stream at a T-junction was investigated. The main objective was to use mass and energy balance equations to predict mass low rates and the temperature of the mixed stream after the T-junction, and then compare these with the measured values. Furthermore, the thermocouple location after the T-junction and…

No matter how one formally define response to intervention (RTI), most definitions contain common components: scientific, research-based instruction; the use of learning rate and level as the basis for determining effectiveness of intervention; and decisions about intensity and duration of interventions based on a student's response to…

In spite of the importance of geological time in evolutionary biology, misconceptions about historical events in the history of life on Earth are common. Glenn (1990) has documented a decline from 1960 to 1989 in the amount of space devoted to the history of life in high school earth science textbooks, but we are aware of no similar study in…

We present a descriptive case study of Terrascope, an innovative, year-long, project-based learning community at MIT. Each year, Terrascope students study a particular environmental or Earth-system problem from a multidisciplinary perspective. Terrascope includes both academic and non-academic components; this paper focuses on the academic…

Families' involvement in their children's science learning at home has numerous benefits, especially when they support children's self-initiated investigations. In a position statement on parental involvement in science education, the National Science Teachers Association (NSTA 2009) stresses the role of parents in the daily reinforcement of…

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…

This study examined the impact of a recently revised science course that engaged preservice teachers in a scaffolded, student-directed inquiry unit on local streams. Upon the completion of the inquiry project, the teacher candidates in the stream study classes demonstrated significantly greater improvement in the personal science teaching efficacy…

To build on classroom experiments and lectures, Daniel Sweeney has his 9th grade earth science students act out scientific concepts on a 15-by-15-foot mat on the floor of the room. Object-tracking cameras mounted on scaffolding around the space collect data based on the students' movements while immersing them in the experience through a video…

Using a conceptual framework constructed around self-efficacy, this study explores specific recruitment programs that may contribute to the development of self-efficacy for students of color in the geosciences. This mixed methods study of geoscience education includes quantitative analysis of the Summer Experience in Earth and Mineral Science…
