We report the results of an experiment designed to elicit students' subjective beliefs about the economic returns to college education. An important feature of our experimental design is the inclusion of financial incentives for accurate reporting. We also consider the extent to which individuals' beliefs about their own returns differ from their…

Computer-based learning environments commonly comprise symbolic as well as static and dynamic pictorial representations, frequently combined with the possibility of modifying them interactively. While multiple, dynamic and interactive external representations have the potential to improve learning in various ways, they also place specific demands…

With each passing year, the public expects more of schools and teachers. Curricula become more complex, student populations become more diverse, responsibilities are added, and, except for resources, very little is taken away. Fundamentally, teachers are held responsible for everyone and everything that goes on in their classrooms, an awesome…

This study examined the writing strategies and text characteristics associated with discovering a scientific principle by writing about an experiment. Sixty-four university students (non-science majors) carried out a physics experiment concerning either buoyancy, or the forces acting on a balance scale, then wrote an informal journal-style note…

The Plaut, McClelland, Seidenberg and Patterson (1996) connectionist model of reading was evaluated at two points early in its training against reading data collected from British children on two occasions during their first year of literacy instruction. First, the network's non-word reading was poor relative to word reading when compared with the…

This article describes a study of the effects of partial replacement of lectures with a system of prescribed reading, supported by weekly objective testing in a second year animal physiology module. Formative tests with feedback within 24 hours were followed a week later with summative tests on the same material, utilising a proportion of the same…

Diffusion and osmosis are central concepts in biology, both at the cellular and organ levels. They are presented several times throughout most introductory biology textbooks (e.g., Freeman, 2002), yet both processes are often difficult for students to understand (Odom, 1995; Zuckerman, 1994; Sanger "et al.", 2001; and results herein). Students…

A recent study suggests that lesions to all major areas of the cholinergic basal forebrain in the rat (medial septum, horizontal limb of the diagonal band of Broca, and nucleus basalis magnocellularis) impair a spatial working memory task. However, this experiment used a surgical technique that may have damaged cerebellar Purkinje cells. The…

Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-[Kappa]B in memory. This was…

The candle burning experiment is usually conducted in lower secondary classes to prove the (about) 20% oxygen in air. The aim of this paper is to show that teachers misinterpret the results of the experiment to satisfy the objectives of teaching this experiment. However, when the results of this experiment are interpreted correctly, the objectives…

o complementary experiments analyzed the acquisition of text content linearization in writing, in French-speaking participants from third to ninth grades. In both experiments, a scrambled text paradigm was used: eleven ideas presented in random order had to be rearranged coherently so as to compose a text. Linearization was analyzed on the basis…

As science teachers, they understand the importance of gaining student interest to promote learning. They know how challenging it is to spark the curiosity to truly engage students in the processes of "doing science." One often-used method of motivation is the demonstration of science in action. Demonstrations such as "discrepant events". They are…

One hundred nine college students participated in an experiment that involved reading a passage and responding to a 20-item multiple choice test. The students were randomly assigned to one of four groups. The four conditions involved reading and copying, reading and highlighting, reading and taking notes, and reading and generating questions.…

Preservice elementary teachers in a conceptual physics course were given multiple resources to use during several inquiry activities in order to investigate how materials were chosen, used, and valued. These students performed significantly better on assessment items related to the inquiry physics activities than on items related to traditional…

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3-8. Each unit uses computers and probeware to support students' investigations of real-world phenomena using probes (e.g., for temperature or…
