Technological design is a core activity in Science, Technology, Engineering and Mathematics (STEM) education. During the design process, students often employ research activities to enhance the quality of their design decisions and to rise above a mere trial-and-error approach to designing. There are many functions of research within the...

Research and design activities are becoming more important in Science, Technology, Engineering and Mathematics (STEM) and D&T (design and technology) education. Research and design are often taught separately from each other, while in professional STEM practices, many projects are neither ‘research only’ or ‘design only’—they are both. In...

Research and design activities are important focus points in international policies for secondary Science, Technology, Engineering and Mathematics (STEM) education. It is up to school teachers to implement and supervise these activities in the STEM classroom. However, not much is known about the attitudes teachers hold towards supervising...

The information that can be extracted from DNA base sequences, is important for our understanding of biology, for insights in disease, and the way we practice medicine. The technology that one uses to determine DNA-base sequences is called ‘DNA sequencing’. A portable device that enables fast and accurate sequencing, can potentially greatly...

Research and design activities are often employed in STEM (Science, Technology, Engineering & Mathematics) education. This study aims to examine students’ attitudes towards doing research and design activities in secondary school, among two groups of students: (1) students that take the quite recently introduced Dutch subject O&O ...

Many theoretical studies predict that DNA sequencing should be feasible by monitoring the transverse current through a graphene nanoribbon while a DNA molecule translocates through a nanopore in that ribbon. Such a readout would benefit from the special transport properties of graphene, provide ultimate spatial resolution because of the single...

Tomographic reconstruction algorithms offer a means by which a tilt-series of transmission images can be combined to yield a three dimensional model of the specimen. Conventional reconstruction algorithms assume that the measured signal is a linear projection of some property, typically the density, of the material. Here we report the use of...

Scanning transmission electron microscopy (STEM) imaging is applied to analyze the electromigration-induced thickness variations of thin polycrystalline films, It is shown that a high angle annular dark field (HAADF) detector is required to minimize the effect of diffraction contact. A further reduction of the diffraction contrast can be...
