In this exercise, an actual chemical reaction, oxidation of iron in air, is studied along with a related analogue simulation of that reaction. The rusting of steel wool is carried out as a class effort. The parallel simulation is performed by students working in small groups. The analogue for the reacting gas is a countable set of discrete marble…

Hiring undergraduate lab assistants in chemistry departments is common in college. However, few studies have focused on promoting undergraduate chemistry learning and thinking skills through this work experience in chemistry teaching laboratories. This article discusses the strategy we implemented in the lab assistant program. The…

In this experiment, students carry out a halogen-metal exchange reaction of methyl 2-iodobenzoate with isopropylmagnesium chloride in THF at 0°C to afford 2-carbomethoxyphenylmagnesium chloride, which is treated with "p"-methoxybenzaldehyde to give a lactone (phthalide) product. This reaction introduces students to the modern method of…

Enzyme kinetics measurements are a standard component of undergraduate biochemistry laboratories. The combination of serine hydrolases and fluorogenic enzyme substrates provides a rapid, sensitive, and general method for measuring enzyme kinetics in an undergraduate biochemistry laboratory. In this method, the kinetic activity of multiple protein…

This paper outlines the rationale underpinning the conception of science education as sociopolitical action, and then presents a critique of such a conception from the perspective of liberal education. More specifically, the paper discusses the importance of the conception of science education as sociopolitical action (e.g., it can provide…

Our goal with this paper is three-fold. We want to increase awareness of inquiry-based learning by presenting the strategy we use to develop and implement lessons and activities. We describe our approach to structuring lessons in mathematics in a way that engages the students by using language and constructs with which they are familiar from other…

Inquiry-based learning (IBL) techniques can be used in mathematics courses for non-majors, such as courses required for liberal arts majors to fulfill graduation requirements. Unique challenges are discussed, followed by adaptations of IBL techniques to overcome those challenges.

iPads are increasingly being put in the hands of children in schools and educational contexts, yet there continues to be larger questions about how they fit into the fabric of daily classroom life and what new stories will emerge (de Certeau, 1984, 1984/2000). In this article, we feature vignettes of data from a 2-year government-funded research…

In the Spring of 2011, two of the authors of this paper taught number theory courses at their respective institutions. Twice during the semester, students in each class submitted proofs of two to three theorems to be peer reviewed by students in the other class. Each student wrote anonymous and formal referee reports of the submitted theorems,…

This paper reports on a planned, professional, postgraduate diploma that aims to develop educators and education officials professionally towards policy making and at the same time bring about transformation in the students' work environment. In order to focus particularly on this aim and also to instil reflexive practices, we will focus on two…

Whilst deficit discourses in classrooms and staff rooms are pervasive and dominant, there is some research which supports teachers disrupting deficit thinking and reconnecting with student "funds of knowledge". Processes for disrupting deficit knowledges tend to assume individual teacher construction of deficit views in conversation with…

Background and Context: in this paper, we argue that integrating Human-Computer Interaction (HCI) into K-12 computing education can present learners with opportunities to develop human-centered design skills as well as higher-order thinking skills. Objective: to address the issues related to the development of HCI forms of expertise, we introduce…

In this essay, Gary Thomas argues that education research repeatedly makes a mistake first noted by Dewey: it misunderstands our science. This misunderstanding has led to attempts to import various putatively scientific precepts into education inquiry. But in reality, he argues, those "scientific" precepts do not characterize scientific endeavor,…

As enrollment-driven postsecondary institutions, Hispanic Serving Institutions (HSIs) must actively find ways to better "serve" their students. Guided by Stanton-Salazar's social capital framework, this study sought to understand how institutional agents use various forms of capital to develop structures that support and empower…

Physical sciences education comes with high expectations for learners to be successfully placed in tertiary institutions in related fields, and developing countries' aspirations to develop advanced and specialised skills to drive economies. However, some of the prevailing instructional strategies in science classrooms work to marginalise learners.…
