“…There is no conventional analogy representing the behavior of an afm probe. Planinšič and Kovač (2008) and Greczyło and Debowska (2006) have used a thin beam and magnetic forces to simulate attraction force in a human-scale teaching model of the afm. Indeed, a good candidate for the analogy should provide a human-scale system combining elasticity and decreasing attraction force, resulting in a hysteretic behavior.…”

This paper aims to evaluate the benefits of using virtual reality and force-feedback to help teaching nanoscale applications. We propose a teaching aid that combines graphic analogies and haptics intended to improve the grasp of non-intuitive nanoscale phenomena for people without prior knowledge of nanophysics. We look specifically at the most important nanophysical phenomenon, namely, the behavior of the probe of an Atomic Force Microscope (AFM) as it approaches a sample. The results from experiments carried out with 45 students indicate that a "magnet-spring" analogy helped beginners to establish the link between the behavior of a probe and its force-distance curve. The addition of haptic feedback increased focus about forces and improved the interpretation of the effect of cantilever stiffness. Haptic feedback and the analogical representation were very much appreciated by the subjects and had an impact on the construction of a mental model. Taken together, our results show a positive influence of using haptic feedback and graphic analogies, especially when students are first exposed to the notions that are in effect at the nanoscale.

“…Accordingly, different solutions have been proposed to get round this problem. Different articles published in Physics Education and in the European Journal of Physics display cheap home made models of AFMs that can be used at school (Greczylo & Debowska, 2006;Planinsic & Kovac, 2008;Zypman & Guerra-Vela, 2001). Yet, even if we haven't found throughout our literature review any scientific article focussing exclusively on the influence of these particular AFM models on pupils' learning, the literature does contain studies of instructional sequences using AFMs.…”

This literature review provides an overview of recent studies on the introduction of nanosciences and nanotechnologies in secondary education. Four salient research topics have emerged from our review of the science education literature: reflections preceding curriculum development on nanosciences and nanotechnologies lessons; research on students' conceptualisations of nano-related concepts; the use of haptic tools to teach nanosciences and nanotechnologies; professional development for secondary schools teachers. In a final critical discussion, the lack of studies in the literature considering nanosciences and nanotechnologies as a socioscientific issue in secondary education is emphasised. In addition, implications for future research as well as suggestions for nanosciences and nanotechnologies curriculum development are considered.

“…Although a number of ingenious implementations of macroscopic analogs/working models of atomic force microscopes (AFMs) have previously been developed and discussed, [5][6][7][8] including LEGO-based variants, [9][10][11] these have each focused on contact mode force microscopy, where the static bending of a cantilever is used to measure tip-sample interactions. Reimer et al 12 took the LEGO design concept much further and developed an elegant analog of a magnetic force microscope, using a microphone to detect the variations in resonant frequency of a scanning cantilever.…”

We describe the design, construction, and operation of a LEGO TM model of a dynamic force microscope, using magnetic forces as an analog of interatomic interactions. The macroscope provides key insights into the operating principles of frequency modulated non-contact atomic force microscopy-currently the scanning probe technique of choice for maximal (i.e., submolecular) spatial resolution-and is, therefore, particularly suited as a project or demonstration for nanoscience education at the undergraduate or postgraduate level.
