Explores how inscriptions are used to create argumentative positions in two classroom episodes. Finds that the classroom activities resembled those of scientific communities in several ways: (1) Real-world, dilemma-driven problems were presented; (2) students evaluated the inscriptions offered in terms of their adequacy for advancing particular…

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)

Discussion of student assessment focuses on issues related to distance education. Topics include purposes of assessment; performance-based assessment; constructivist approaches; examples of alternative assessments, including portfolios, projects, and problem-based learning activities; implementation; and distance education as a catalyst for…

When faced with real-world problems, students devise accurate, logical, and creative solutions using skills connecting to different subject areas. Students are intrigued by assignments involving preservation of species and design of environmentally friendly products and transit systems. Problem-based learning depends on coaching, modeling, and…

Focuses on problem-based curriculum students' generation of learning issues that are guidelines for their individual study. Investigates how many learning issues can be classified as being of good quality and presents examples of well and poorly formulated ones. (DDR)

Describes searching and sharing of knowledge on virtual networks, based on experiences gained when hosting virtual knowledge networks at Tampere University of Technology in Finland. Discusses information and knowledge management studies; role of information technology in knowledge searching and sharing; implementation and experiences of the…

Project ProBase (problem-based technology curriculum) is a National Science Foundation funded project designed to develop an innovative curriculum that more adequately prepares high school technology education students for success in advanced technical studies at the community college level. The purpose of the project is to design and test…

The purpose of this quasi-experimental study was (a) to determine if there was a difference in knowledge achievement by Thailand's vocational students instructed using constructivist instruction (with open-end dialogue, problem-based learning, and cooperative learning) and using traditional instruction (with lectures, directed demonstrations, and…

This article discusses "Family Secrets," a problem-based learning (PBL) curriculum module that focuses on the bioethical implications of genetic testing. In high school biology classrooms throughout New York State, students are using "Family Secrets" to learn about DNA testing; Huntington's disease (HD); and the ethical, legal,…

In an extension of research examining student-centered pedagogy, the present case study examined how at-risk students used Alien Rescue, a problem-based learning (PBL) software program for middle school science. Twenty-nine participants were observed and interviewed over the twelve class days in which they were engaged in Alien Rescue. Students'…

This paper makes a critical assessment of problem-based learning (PBL) in geography. It assesses what PBL is, in terms of the range of definitions in use and in light of its origins in specific disciplines such as medicine. It considers experiences of PBL from the standpoint of students, instructors and managers (e.g. deans), and asks how well…

In this case study, the aim was to implement project-based learning by utilizing e-portfolio assessment in a small-scale classroom (N = 8). The compulsory Design, Development, and Evaluation of Educational Software course in the curriculum of the Department of Computer Education and Instructional Technology was selected due to its strong…

An instructor contemplating a course transformation to incorporate a student-centered learning environment may feel faced with what seems like a high-wire balancing act--a constantly renegotiated compromise between students' legitimate needs for structure, well-understood expectations, and good grades and instructors' foreknowledge that the path…

Partnerships between members of the scientific community at institutes of higher education and the K-12 education community are an increasingly popular approach to science education reform (Atkin, 1989; Chatman, 2002; Sussman, 1993; NSF, 2003a, 2003b). Although the word "partnership" can mean many things to many people, we use the term…

This study investigated students' conceptions of constructivist learning activities in a problem-based learning (PBL) and a traditional curriculum. We examined whether students who have chosen for a problem-based curriculum have different conceptions of constructivist assumptions compared to students who have chosen to be enrolled in a…
