A participatory learning approach, combined with both a traditional and a competitive assessment, was used to motivate students and promote a deep approach to learning biochemistry. Students were challenged to research, author, and explain their own multiple-choice questions (MCQs). They were also required to answer, evaluate, and discuss MCQs…

Based on a three-year-long ethnography of the hobby of model rocketry, I present a practice-centered theory of interest relationships--that is, the pattern of long-term, self-motivated engagement in open-ended practices that has been theorized under the concept of "individual interests". In contrast to extant theories of individual interests, in…

The discovery or re-construction of scientific explanations and understanding based on experience is a complex process, for which school learning often uses shortcuts. On the basis of the example of analyzing real seismic measurements, we propose a computer-facilitated collaborative learning scenario which meets many of the requirements for…

A priority for all biology teachers must be for students to leave the classroom with a broad knowledge and understanding of science. Students need to be critical of science, analyze science, and relate new science knowledge to their daily lives. Unfortunately, many students are not reaching this goal. One strategy for making science laboratories…

We examined the effects of teacher supports in enhancing teachers' open-ended questioning in pre-k activities. The blended teacher supports included online video demonstrations of questioning techniques and companion workshop activities. Twenty-five teachers received the blended supports while the control group did not. The data consisted of…

This paper reports on the autonomy Grade 9 learners (13-14 years) are given when doing science investigations. The study adopted a mixed methodology research design which involved the collection of both quantitative and qualitative data. Quantitative data were collected by means of questionnaires which were administered to 55 teachers. Qualitative…

Invention activities challenge students to tackle problems that superficially appear unrelated to the course material but illustrate underlying fundamental concepts that are fundamental to material that will be presented. During our invention activities in a first-year biology class, students were presented with problems that are parallel to those…

This research investigated the effect of reflective discussions following inquiry-based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty-eight grade six students from a Lebanese school participated in the study. The study used a pretest-posttest control-group…

The objective of this study is to evaluate the efficiency of the first two group applications of the project named "We are Learning about the Soil with Tipitop and His Friends" within the scope of the project group activities of The Scientific and Technological Research Council of Turkey (TUBITAK) "Schools of Nature and…

This article discusses how, as part of a National Science Foundation-funded internship program, the authors translated smart papers into an exciting and informative activity for the middle school classroom. This activity opens students' eyes to an everyday technology and inspires them to ask questions about other hidden technologies that they…

A simple, sensitive, and portable viscometer has been designed using an opto-mechanical mouse. The viscosity of a fluid is measured using the infrared light-emitting diodes and the optical diodes of an opto-mechanical mouse. These components are positioned near the top and bottom of a glass tube containing the fluid to be measured. The viscosity…

The use of "Origami" is presented as an accessible and transferable modeling system through which to convey the intricacies of molecular shape and highlight structure-function relationships. The implementation of origami has been found to be a versatile alternative to conventional ball-and-stick models, possessing the key advantages of being both…

Electrospinning has been used to create nanofibers for filtration devices, tissue engineering, and protective clothing. Although electrospinning is now widely studied, because of the expensive equipment required and the advanced nature of this topic, it is not commonly found in high school science labs. Through grants from the Ohio State…

This paper presents a wind power system laboratory activity and an outline for evaluating student performance in this activity. The work described here was to design and implement the laboratory to assist teachers in achieving the teaching objective of this activity. The laboratory teaching activities introduce energy sources, wind energy…

Laboratory work is considered essential in promoting students' learning of science and of scientific inquiry. What the students perceive as important to learn from a regular laboratory exercise is probably affected by the teacher's objectives. We study the extent to which one teacher's objectives are fulfilled during lab work, and how…
