In this study, we analyzed the descriptive knowledge and mental models of the phenomenon of tides manifested by 111 preservice primary teachers. The instrument employed is an open-ended questionnaire, analyzed by means of an approach that explores the descriptions, explanations, and predictions in respect of this phenomenon by our subjects. First,…

A science café and a concert with a panel discussion were held with public audiences to communicate information about global change and ecosystem soundscapes. Both events were evaluated through: (i) post-event surveys to measure global change perceptions, awareness, and attitudes; (ii) skin biosensors to measure the engagement levels of a…

In this mixed method study, we analyse the effectiveness of two pedagogical approaches -- one model-based and another non-model-based -- for developing secondary students' understanding of the phenomenon of increase in Earth's average surface temperatures, a core dimension of global climate change (GCC). Building on past research on teaching and…

In an attempt to evaluate the impact of the use of a simulation on the learning concepts of relative dating, a study was carried out with first year students at the Technical High School of the city of Taza (Morocco). The method of the study was semi-experimental research design with pre-test and post-test. The study used two groups including the…

Promoting collaboration and discourse in asynchronous online courses is challenging; students need something engaging to talk about, a communications medium in which to fluidly discuss it, and a social environment that supports discourse. We designed a fully online introductory geoscience lecture and lab course called Geology Goes Hollywood that…

People make sense of the world by comparing and relating new information to their existing landmarks. Each individual may have different landmarks, developed through idiosyncratic experiences. Identifying specific events that constitute landmarks for a group of learners may help instructors in gauging students' prior knowledge and in planning…

As an aid for teaching phase equilibria to undergraduate students of igneous and metamorphic petrology, we have designed a laboratory exercise that allows them to create a phase diagram from data produced by differential scanning calorimetry. By preparing and analyzing samples of naphthalene and phenanthrene, students acquire hands-on insight into…

Students do not have a good understanding of how rocks form. Instead, they have many non-scientific alternative conceptions to explain different aspects of rock formation. Using 10 interviews and nearly 200 questionnaires filled out by students at four different colleges, we identified many alternative conceptions students have about rock…

Presents a study to examine the effects of a verbal teaching strategy versus a strategy providing instruction using activities and manipulatives in four seventh grade earth science classes with students of varying cognitive abilities (n=83). Results indicate that students with more cognitive structures perform better and that using manipulatives…
