There is now a significant research literature devoted to reconceptualizing scientific activities, such as modeling, explanation, and argumentation, to realize a vision of science-as-practice in classrooms. As yet, however, not all scientific practices have received equal attention. "Planning and Carrying out Investigations" is one of…

Recent emphasis on learning biology through scientific investigations has focused instruction on understanding and using scientific evidence. To unpack the complexities of evidentiary reasoning, here we present a novel laboratory investigation for teaching the Hardy Weinberg Equilibrium (HWE) in an introductory biology laboratory course that was…

This article describes a three-dimensional 5E (Engagement, Exploration, Explanation, Elaboration, Evaluation) lesson that investigates 3-LS4-1: Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived. A phenomena-based approach was used to engage third graders in the story of Maya, who…

This article is aimed at teachers already experienced with activities involving small, student-collected data sets and who are now ready to begin working with large, online data sets collected by scientists and engineers. The authors discuss challenges, instructional strategies, and sources of appropriate lesson plans. With guidance, plus online…

A focus of reforms in standards, learning environments, teacher preparation programs and professional development is to support teachers' and students' engagement with scientific practices such as argumentation, modeling and generating explanations for real-world phenomena (NRC, 2011). Engaging in these practices in authentic ways…

Although students are enthusiastic when engaging in hands-on investigations, they can find it challenging to make sense of their data and to create explanations using evidence from their investigations. The authors spent a year designing and testing strategies in a science classroom to better assist elementary students in constructing and…

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 paper reports on a national study that explored primary pupils' attitudes towards and experiences of school science in the Republic of Ireland. The study focussed on collecting data from children and in doing so recognises the importance of children's views as an essential part of reviewing curriculum implementation. The findings of this…

We developed an instrument to systematically investigate student conceptual understanding of the relationships between the directions of net force, velocity, and acceleration in one dimension and report on data collected on the final version of the instrument from over 650 students. Unlike previous work, we simultaneously studied all six possible…

We report on the adaptation of the small enrollment, lab and discussion based physical science course, "Physical Science and Everyday Thinking" (PSET), for a large-enrollment, lecture-style setting. Like PSET, the new "Learning Physical Science" (LEPS) curriculum was designed around specific principles based on research on learning to meet the…

Forensic entomologists utilize insects (particularly flies) to establish the time interval between death and body discovery. This important piece of information may answer questions as to the circumstances of the individual's death and insects are now routinely utilized and recognized as being important forensic indicators. Of extreme importance…
