Purpose The purpose of this paper is to explore what key competencies and characteristics of teachers are needed for integrated Science, Technology, Engineering and Mathematics (STEM) teaching and to investigate teachers’ perceptions on how important those competencies are and how often they are executed. Design/methodology/approach An exploratory sequential mixed methods approach was used to investigate key characteristics of integrated STEM teaching competencies and the level of their importance and performance as perceived by teachers. By using behavioral event interview technique, qualitative data were collected from professional secondary teachers in science, math and technology subjects. An instrument was constructed based on the result of qualitative research; and a survey was conducted with 48 STEM teachers working in South Korea. The mean values between importance and performance of integrated STEM teaching competencies were compared. A perceived importance level of each item was compared with a practice level by using importance-performance analysis. Findings As a result of qualitative research, in total 21 items were constructed as detailed characteristics of each domain of integrated STEM teaching competencies, which provide insights about teachers’ perceptions of teaching competencies that are critical for integrated STEM education. A comparison of means between importance and performance of integrated STEM teaching competencies showed that whereas teachers considered each of these items to be of significant importance in their overall evaluation of the integrated STEM teaching competencies, they are not performing at a level that reflects the assigned importance. Practical implications This research results provide information for future research on how to implement an integrated STEM education initiative at the secondary school level, for planning teacher training programs, pre-service teacher education and related educational policies. Originality/value South Korea has focused on integrated STEM education to raise talented human resources in the fields of science and technology. However, many teachers have experienced serious difficulties and troubles in executing integrated STEM education. It is necessary to figure out key competencies and characteristics of teachers to facilitate integrated STEM teaching.

It has repeatedly been show that with conventional electron microscopes very fine electron probes can be produced, therefore allowing various micro-techniques such as micro recording, X-ray microanalysis and convergent beam diffraction. In this paper the function and performance of an SIEMENS ELMISKOP 101 used as a scanning transmission microscope (STEM) is described. This mode of operation has some advantages over the conventional transmission microscopy (CTEM) especially for the observation of thick specimen, in spite of somewhat longer image recording times.Fig.1 shows schematically the ray path and the additional electronics of an ELMISKOP 101 working as a STEM. With a point-cathode, and using condensor I and the objective lens as a demagnifying system, an electron probe with a half-width ob about 25 Å and a typical current of 5.10-11 amp at 100 kV can be obtained in the back focal plane of the objective lens.

A cylindrical mirror analyser (CMA) has been built with a parallel recording detection system. It is being used for angular resolved electron spectroscopy (ARES) within a SEM. The CMA has been optimised for imaging applications; the inner cylinder contains a magnetically focused and scanned, 30kV, SEM electron-optical column. The CMA has a large inner radius (50.8mm) and a large collection solid angle (Ω > 1sterad). An energy resolution (ΔE/E) of 1-2% has been achieved. The design and performance of the combination SEM/CMA instrument has been described previously and the CMA and detector system has been used for low voltage electron spectroscopy. Here we discuss the use of the CMA for ARES and present some preliminary results.The CMA has been designed for an axis-to-ring focus and uses an annular type detector. This detector consists of a channel-plate/YAG/mirror assembly which is optically coupled to either a photomultiplier for spectroscopy or a TV camera for parallel detection.
