Drawing, constructing, and explaining a model of a given abstract phenomenon is a challenging task. In this study, students were engaged in the "Project-Based Inquiry Science (PBIS)-Air Quality" learning unit, as part of their chemistry curriculum. The study aim is to determine how well students understand chemistry conceptually after…

A new project-based laboratory (PJBL) was developed for general chemistry students to tackle the steps involved in chemical water quality analysis using an accessible, real-world hydrologic system (the lakes of the Lower Grand Coulee, Washington). This PJBL was developed in a joint general chemistry and environmental geology course by a…

Over the past 20 years, significant effort has been devoted to advancing the modular approach to teaching chemistry laboratory courses. The development and implementation of two modules are presented here for teaching a second-semester physical chemistry laboratory course using the modular approach: an inquiry-based module concerning proteins and…

Students entering into a quantitative analysis course often struggle with connecting theoretical aspects of concepts from lecture to hands-on applications in the laboratory setting. A one-semester quantitative analysis course was redesigned to integrate active learning with a project-based curriculum that incorporated structured review of…

This study explores fluctuation in students' emotional state and motivational goals during a learning project that requires self-regulation. The research asks the following questions: (1) How do students' emotional state and motivational goal fluctuate between the gStudy learning sessions during a two-month project? (2) How do students with…

A single semester molecular biology laboratory has been developed in which students design and execute a project examining transcriptional regulation in "Saccharomyces cerevisiae." Three weeks of planning are allocated to developing a hypothesis through literature searches and use of bioinformatics. Common experimental plans address a…

Evolutionary experiments are usually difficult to perform in the classroom because of the large sizes and long timescales of experiments testing evolutionary hypotheses. Computer applications give students a window to observe evolution in action, allowing them to gain comfort with the process of natural selection and facilitating inquiry…

Imagine middle and high school science classes without a science fair. Participation in science fairs is declining (Harmon 2011), a trend that some teachers, parents, and students find disturbing. The authors opine that the decline in science fairs calls for critically reviewing the potential disconnect between the aims and outcomes of science…

Background: Design and science inquiry are intertwined during engineering practice. In this study, we examined the relationship between design behaviors and scientific explanations. Data on student design processes were collected as students engaged in a project on designing energy-efficient buildings on a blank square city block surrounded by…

A five-week miniproject is described for an upper-division experimental organic chemistry course. The activities include synthesis of a phenylboronic acid via a Grignard reaction and its use in a Suzuki-Miyaura cross-coupling reaction. Technical skills and concepts normally presented in practical organic chemistry courses are covered, including…

This paper provides a systematic review of instruments that have the potential to measure the quality of project-based science and technology (S&T) learning environments in elementary school. To this end, a comprehensive literature search was undertaken for the large field of S&T learning environments. We conducted a horizontal bottom-up…

Here we present a multidisciplinary educational unit intended for general, advanced placement, or international baccalaureate-level high school science, focused on the three-dimensional structure of proteins and their connection to function and disease. The lessons are designed within the framework of the Next Generation Science Standards to make…

"PlantingScience" is an award-winning program recognized for its innovation and use of computer-supported scientist mentoring. Science learners work on inquiry-based experiments in their classrooms and communicate asynchronously with practicing plant scientist-mentors about the projects. The purpose of this study was to identify specific…

Students need practice in proposing hypotheses, developing experiments that will test these hypotheses, and generating data that they will analyze to support or refute them. I describe a guided-inquiry activity based on the "tongue map" concept, appropriate for middle school and high school students.

One author shares the unique opportunity to be immersed in the science of "sound at work" through participation in NOAA's (National Oceanic and Atmospheric Administration) Teacher at Sea Program. A third- through fifth-grade learning outcome within the Nature of Science section of the "Next Generation Science Standards"…
