Pick a Number … Any Number?

A recent classroom revelation caused us to reconsider the adequacy of the instructions offered in our textbooks for one of our most elementary quantitative methods. Specifically, we found that many students were mystified concerning how to pick an initial objective function value when plotting an isoprofit line in order to graphically solve a linear programming problem. We observed that this seemingly insignificant issue was causing a surprising amount of wasted time, confusion, and even anxiety. Our experience indicated that students do not necessarily possess any consistent intuition for choosing an appropriate initial value. We confirmed this perception through informal experimentation. We reviewed several textbooks and found that most simply do not bother to address this issue. Therefore, we devised a simple, comprehensible method which we have taught our students to resolve or avoid this problem. Although we quickly found the method to be helpful for many students, we conducted an experiment to formally measure its effect.     

‘Studies have shown that …’ how to read a statistical study

This article provides some background for a classroom discussion of statistical research studies. The history of cigarettes and warning labels in the USA is reviewed here in order to demonstrate the challenges of statistical research and communication.     

“He ain't heavy …”: Lessons from backpacking

Camille Consolvo and Mike Dannells share the skills required to plan and execute a successful days‐long backpacking trip, which they have discovered are also useful in advising student leaders.     

“Translated,it is: …” — An Ethics of Transreading

Inspired by Friedrich Nietzsche's idea of philology and William Gass's concept of transreading, Huiwen (Helen) Zhang employs “transreader” to suggest the integration of four roles in one: reader, translator, writer, and scholar. “Transreader” recognizes that close reading, literary translation, creative writing, and cultural hermeneutics are interdependent activities with intertwined goals: to transfer, transvalue, transform, and transcend the canon. From this perspective, Lu Xun, China's Nietzsche, is a twentieth‐century transreader of the canon, and his prose poem “Revenge (The Second)” delivers a self‐referential ethics of transreading. Zhang's transreading of this poem shows why slow reading is today more necessary than ever, in what sense translation is a universal dilemma, how humanity grows when its expression grows more subtle, and that transreading opens a space for genuine communication.     

“It's not as if we've been teaching them…” reflective thinking in the outdoor classroom

Research undertaken during a six week mountaineering expedition to Iceland in July 2003 set out to investigate approaches to facilitating the reflective process in 20 participants aged between 14 and 18. A number of models were examined to help determine the educational philosophy underpinning the expedition. The research methods involved documentary searches, observations and semistructured interviews. Findings suggest that the approach of expedition leaders accorded with the 'mountains speak for themselves' model as the leadersmade little or no attempt to encourage, facilitate or enable reflection on the part of participants. With few exceptions the participants did, however, engage in reflective thought both about the activities they had been involved in and the holistic benefits of the expedition. The findings suggest that whilst the facilitator/interventionist model and the Kolb cycle do little to explain the pedagogy within this expedition, there was evidence of much reflective learning from the participants.     

‘This baby…it isn't alive.’ Towards a community of learners for vocational orientation

The aim of this study is to contribute to the innovation of pre‐vocational education, in particular, students' orientation at possible future occupations. From our theoretical understanding, vocational orientation that makes sense to students requires them to be part of a ‘community of learners for vocational orientation’. In such a community, students are stimulated to learn deliberately while participating in vocational practices. In this article we distinguish four parameters to define a community of learners for vocational orientation. We then present the results of a collective instrumental case study into teaching‐learning processes in four classes in two pre‐vocational secondary schools. Data were collected through classroom observations, a series of interviews with teachers and students. The interviews focused on eight ‘critical incidents’ recorded during classroom observations. The results show that the parameters ‘shared learning’ and ‘meaningful learning’ are more manifest in the teaching‐learning process than ‘reflective learning’ and ‘a focus on transferable learning outcomes’. The article concludes with a discussion of the limits of working in simulated work situations in school for realizing effective pre‐vocational education.
