"The Chemistry of Perfume" is a lab-only course for nonscience majors. Students learn fundamental concepts of chemistry through the context of fragrance, a pervasive aspect of daily life. The course consists of laboratories pertaining to five units: introduction, extraction, synthesis, characterization, and application. The introduction unit…

The ability to couple problem solving both to the understanding of chemical concepts and to laboratory practices is an essential skill for undergraduate chemistry programs to foster in our students. Therefore, chemistry programs must offer opportunities to answer real problems that require use of problem-solving processes used by practicing…

Infants have been described as "statistical learners" capable of extracting structure (such as words) from patterned input (such as language). Here, we investigated whether prior knowledge influences how infants track transitional probabilities in word segmentation tasks. Are infants biased by prior experience when engaging in sequential…

A seven-week "gene to protein" laboratory sequence is described for an undergraduate biochemistry laboratory course. Student pairs were given the task of introducing a point mutation of their choosing into the well studied protein, enhanced green fluorescent protein (EGFP). After conducting literature searches, each student group chose the…

A reference electrode is one of the prerequisites of electrochemical investigations. Many electrodes are commercially available but are expensive and prone to accidental breakage by students. Here we report a simple, easy-to-fabricate, inexpensive, reliable, unbreakable, and reproducible Ag/AgCl reference electrode. The empty barrel of a…

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…

A basic setup for data acquisition and analysis from an oscillatory circuit is described, with focus on its application as either low-pass, high-pass, band-pass or band-reject frequency filter. A homemade board containing the "RLC" elements allows for the interchange of some of them, in particular, for the easy change of the "R" value, and this…

The role of research in university institutions whose primary task is to provide teaching remains ambiguous and controversial. In principle, all university teaching is based on pertinent research. However, for some university units, such as language centres, the basic tasks, and consequently their funding, are very often defined in a manner which…

This paper discusses the design and implementation of laboratories and course projects using LabVIEW in an instrumentation course. The pedagogical challenge is to enhance students' learning of digital communication using LabVIEW. LabVIEW was extensively used in the laboratory sessions, which better prepared students for the course projects. Two…

The success of science education reform initiatives depends considerably on the teachers. Effective professional development opportunities have been shown to encourage and support teachers in their adoption of inquiry-based teaching practices. In particular, it has been argued that an effective means for science teachers to learn about science…

As a result of recent developments in digital technologies, new genres as well as new contexts for communication are emerging. In view of these developments, this article argues that the scope of English language teaching be expanded beyond the traditional focus on speech and writing to the production of multimodal ensembles, drawing on a range of…

In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning…

This article describes an innovative neuropsychopharmacology laboratory that can be incorporated into any research methods class. The lab consists of a set of interconnected modules centered on observations of methamphetamine-induced behavioral changes in mice and is designed to provide students with an opportunity to acquire basic skills…

Science education reform documents identify nature of science (NOS) as a critical component of scientific literacy and call for universities, colleges, and K-12 schools to explicitly integrate NOS learning into science curricula. In response to these calls, this study investigated the classroom practices of nine graduate assistants (GAs) who…

A Project Based Learning (PBL) methodology was used in the practical laboratories of the Advanced Physical Chemistry department. The project type proposed simulates "real research" focusing on sol-gel synthesis and the application of the obtained sol as a stone consolidant. Students were divided into small groups (2 to 3 students) to…
