With the growing awareness of green chemistry, it is increasingly important for students to understand this concept in the context of laboratory experiments. Although microwave-assisted organic synthesis has become a common and invaluable technique in recent years, there have been few procedures published for microwave-assisted inorganic synthesis…

Mass spectrometry (MS) has been gaining in popularity in recent years owing in large part to the development of soft-ionization techniques such as matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI). These soft-ionization techniques have opened up the field of MS analysis to biomolecules, polymers, and other high…

In this laboratory experiment, students quantitatively determine the concentration of an element (mercury) in an environmental or biological sample while comparing and contrasting the fundamental techniques of atomic absorption spectrometry (AAS) and atomic fluorescence spectrometry (AFS). A mercury analyzer based on sample combustion,…

Learning Management Systems are instructional platforms that offer opportunities to address the development of core competencies across disciplines. The emergence of instructional models which place greater emphasis on core skill development in science education help to build interdisciplinary communities through curricular connectivity and…

As part of a longitudinal study into identity development in upper-level physics students a phenomenographic research method is employed to assess the stages of identity development of a group of upper-level students. Three categories of description were discovered which indicate the three different stages of identity development for this group…

Laboratory education can play a vital role in developing a learner's autonomy and scientific inquiry skills. In an innovative, mutation-based learning (MBL) approach, students were instructed to redesign a teacher-designed standard experimental protocol by a "mutation" method in a molecular genetics laboratory course. Students could…

Although the level of cognitive behaviours is continually controlled in school environments, affective behaviours cannot be both acquired and measured in a planned manner way. In fact, the functionality of educational activities, which are orientated towards cognitive targets, can be enhanced by placing more emphasis on the affective dimension.…

Several institutions have redesigned traditional learning spaces to better realize the potential of active, experiential learning. We compare student performance in traditional and active learning classrooms in a large, introductory biology course using the same syllabus, course goals, exams, and instructor. Using ACT scores as predictive, we…

This study compared two common types of online information literacy tutorials: a streaming media tutorial using animation and narration and a text-based tutorial with static images. Nine sections of an undergraduate biology lab class (234 students total) were instructed by a librarian on how to use the BIOSIS Previews database. Three sections…

The role of student interactions in learning situations is a foundation of sociocultural learning theory, and social network analysis can be used to quantify student relations. We discuss how self-reported student interactions can be viewed as processes of meaning making and use this to understand how quantitative measures that describe the…

Field trips and the outdoor classroom are a vital part of many areas of education. Ideally, the content should be taught within a realistic environment rather than just by providing a single field trip at the end of a course. The archaeo-astronomy project located at Nottingham Trent University envisages the development of a virtual environment…

Scientific literacy is an important goal for science education, especially within controversial socioscientific issues. In this study, we analysed 143 students' research reports about stem cell research (SCR) for how they addressed specific source evaluation criteria provided within the assignment. We investigated students' opinions about SCR, how…

A model of expertise in physics problem solving was tested on undergraduate science, physics, and engineering majors enrolled in an introductory-level physics course. Structural equation modeling was used to test hypothesized relationships among variables linked to expertise in physics problem solving including motivation, metacognitive planning,…

It is widely held among biology teachers that fieldwork is valuable, but little is heard about students' perception of fieldwork or about the reasons for their liking or disliking fieldwork. This paper uses data from students to explore the hypotheses (1) that biology students with a positive perception of fieldwork have a less positive perception…

Visuals (maps, charts, diagrams and illustrations) are an important tool for communication in most scientific disciplines, which means that scientists benefit from having strong visual communication skills. This dissertation examines the nature of competence in visual communication and the means by which scientists acquire this competence. This…
