Our study, focused on classroom-based research at the introductory level and using the Phage Genomics course as the model, shows evidence that first-year students doing research learn the process of science as well as how scientists practice science. A preliminary but notable outcome of our work, which is based on a small sample, is the change in…

Science literacy involves knowledge of both science content and science process skills. In this study, we describe the Assessment of Critical Thinking Ability survey and its preliminary application to assess the critical thinking skills of undergraduate students, graduate students, and postdoctoral fellows. This survey is based on a complex and…

This article describes a comprehensive treatment of experimental enzyme kinetics strongly coupled to electronic data acquisition and use of spreadsheets to organize data and perform linear and nonlinear least-squares analyses, all in a manner that promotes development of important reasoning skills. Kinetic parameters are obtained for the stable…

Science teachers and graduate students have developed activities and assessment tools that begin to help students make the distinction between data and evidence. Two activities are covered in this article. (Contains 1 resource and 2 figures.)

Taking children out of the classroom to learn in a totally different environment can be very rewarding for both the children and the teacher. Part of the excitement is the unfamiliarity of the place, which has its positive sides but can lead to a lack of focus. As part of the Darwin 200 celebrations in 2009, the Charles Darwin Trust and…

The purpose of this research was to investigate the conceptions and misconceptions of young children (ages 3-8) related to science concepts, skills, and phenomena. These conceptions and misconceptions were investigated within the framework of the Pennsylvania Early Learning Standards for Pre-Kindergarten and the Pennsylvania Standards for…

Science teachers today need engaging projects to help students build 21st-century skills (NSTA 2011). Contemporary young adult literature (YA lit) can form the basis of one such project. YA lit--a genre of fiction geared toward 2 to 20-year-olds--opens a powerful avenue to connect with students and cover science topics in greater depth. YA lit is…

In this article we report on the use of a graduate "Special Topics" course to provide vital research and practical laboratory experience, within the context of developing a chemical process to manufacture biodiesel from algal sources. This course contained several key components that we believe are necessary skills in graduate research: 1) a…

Our study investigated the effect of utilizing home related science activities on student's performance in some basic science concepts. The concepts considered were heart energy, ecology and mixtures. The sample consisted of two hundred and forty (240) basic junior secondary two (BJSS11) students drawn from a population of five thousand and…

In this paper we explored whether engaging in two inquiry skills associated with data collection, designing controlled experiments and testing stated hypotheses, within microworlds for one physical science domain (density) impacted the acquisition of inquiry skills in another domain (phase change). To do so, we leveraged educational data mining…

In eighth grade, students usually learn about forces in science class and linear relationships in math class, crucial topics that form the foundation for further study in science and engineering. An activity that links these two fundamental concepts involves measuring the distance a spring stretches as a function of how much weight is suspended…

Studies of high-school science course sequences have been limited primarily to a small number of site-specific investigations comparing traditional science sequences (e.g., Biology-Chemistry-Physics: BCP) to various Physics First-influenced sequences (Physics-Chemistry-Biology: PCB). The present study summarizes a five-year program evaluation…

The aim of this study was to investigate the effect of Problem-Based Learning (PBL) on undergraduate students' learning about solutions and their physical properties, and on their scientific processing skills. The quasi experimental study was carried out through non-equivalent control and comparison groups pre-post test design. The data were…

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2-year Master of Teaching program. A specific program goal was to…

Science educators regard long-term investigations as one impactful form of teaching science through inquiry in K-12 classrooms. While we have idealized notions of what this work looks like, we have few, if any, descriptive studies about investigations that engage students in sustained, focused work over a period of time longer than a few days or…
