This action research study aimed to find ways to adjust my practice by incorporating inquiry-based, science activities and virtual simulations to improve student conceptual understanding of physical and chemical changes. A multi-lesson, curricular intervention combining inquiry-based activities and virtual simulations was developed using…

In this empirical study we examined the effect of a literacy-infused science intervention on fifth grade economically challenged students' science achievement in the curriculum-based and standardized assessments. A total of 27 treatment students and 20 comparison students from two intermediate schools in a rural district in South Texas in the…

In this paper, we propose computational scientific inquiry (CSI) as an innovative model for learning important scientific knowledge and new practices for "doing" science. This approach involves the use of a "game-like" virtual world for students to experience virtual biological fieldwork in conjunction with using an agent-based…

This research is conducted among 65 seventh graders (12-14 years old) who attend introductory course on physics. Tests and interviews are used to trace the roots of the students' misconceptions about mass. Results from the research reveal serious weaknesses in students' understanding of concept of mass, and its confusion with concepts of density…

The Next Generation Science Standards (NGSS)--now in development--will be based on "A Framework for K-12 Science Education" released by the National Research Council last summer. The "Framework" identifies seven scientific and engineering practices that should be used in science classrooms. These practices reflect the multiple ways in which…

This study investigated how the format of verbal instructions in computer simulations and prior knowledge (PK) affected 8th graders' cognitive load (CL) level and achievement in a multimedia learning environment. Although PK was not found to significantly affect student performance and CL level, instruction format was found to impact both.…

One-size-fits-all educational innovations do not work because they ignore contextual factors that determine an intervention's efficacy in a particular local situation. This paper presents a framework on how to design educational innovations for scalability through enhancing their adaptability for effective usage in a wide variety of settings. The…

This study investigated novel pedagogies for helping teachers infuse inquiry into a standards-based science curriculum. Using a multi-user virtual environment (MUVE) as a pedagogical vehicle, teams of middle-school students collaboratively solved problems around disease in a virtual town called River City. The students interacted with "avatars" of…

In this paper, we present the results of an exploratory study into the relationship between student self-efficacy and guidance use in a Multi-User Virtual Environment (MUVE) science curriculum project. We describe findings from a sample of middle school science students on the combined impact on learning of student self-efficacy in scientific…

Background: Most policy doctrines promote the use of scientific inquiry in the K-12 classroom, but good inquiry is hard to implement, particularly for schools with fiscal and safety constraints and for teachers struggling with understanding how to do so. Purpose: In this paper, we present the design of a multi-user virtual environment (MUVE)…
