- Downloading of the abstract is permitted for personal use only. The Origins Space Telescope (OST) will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. How did the universe evolve in response to its changing ingredients? How common are life-bearing planets? To accomplish its scientific objectives, OST will operate at mid- and far-infrared wavelengths and offer superlative sensitivity and new spectroscopic capabilities. The OST study team will present a scientifically compelling, executable mission concept to the 2020 Decadal Survey in Astrophysics. To understand the concept solution space, our team studied two alternative mission concepts. We report on the study approach and describe both of these concepts, give the rationale for major design decisions, and briefly describe the mission-enabling technology.

- The relentlessly accelerating global educational demands for teaching English as a Second or Foreign Language (ESL/EFL) in multiple, diverse, and often remote geographic locations constitute new challenges for academic institutions, teacher training and preparation programs, and teachers themselves. This study describes a novel approach where five elementary school preservice teachers teaching ESL/EFL borrowed an iPad mini from their teacher training institution customized with specific apps to record a series of five teaching sequences during their teaching practice placement in elementary schools in Tanzania and Kenya. All recorded sessions were uploaded to a Moodle Virtual Learning Environment (VLE)site specially constructed for the purpose of the teaching practice course. Results indicate that, apart from their experienced instructors’ feedback on their teaching practice, the recorded sessions formed constructive tools for self-reflection, self-evaluation and the pursuit of possible paths for improvement.

- In recent years, schools, municipalities, and universities have madeincreasing use of educational technologists (edtechs) to support teaching staff inthe delivery of technology-based courses in face-to-face, blended, or purely onlineformats. This paper is a case study focusing on the types of training and supportprovision provided by three edtechs within the arts and humanities faculty of a largeprovincial university in southern Sweden. The edtechs also identify a number ofobstacles in the way of developing Information and Communication Technology(ICT) and computer assisted language learning expertise among teaching staff.
