Today e-learning is a term which is commonly used, but does not have a universally accepted definition, but it can be considered as technology-enhanced learning, where all types of digital technologies are used to support the learning process. Over the years some new functionality has appeared as mobile and wireless technologies (m-learning) and digital television provided possibilities for interactive study materials management (tv-learning). Latest options for training process acceleration are offered by virtual and augmented reality (VR/AR) technologies. The aim of this paper is to find solution for appropriate hardware selection before constructing VR/AR system for training needs focusing on platforms used for operators preparation to work with industrial equipment. In the beginning of the paper all hardware devices for such systems are summarized and explained. Then by using set theory and combinatorics all possible sets of input/output devices are described and calculated. Next dynamic modelling is used to create deterministic, static simulation model with an aim to ease the process of hardware selection for VR/AR training systems development. Simulation model is used for development of two pilot projects.

Training academic writing is proposed as a topical subject within the teachers' education study programme on graduate level at Latvia University of Agriculture. In order to promote the development of students personality self-actualization, we are called for introducing new digital technology as teaching-learning method contributing to opening up opportunities in training academic writing at University. How can we use the digital environment for developing formal academic writing technique in our students? The main argument is that digital environment is a key factor for changes in the teaching-learning process and organization of Teachers' Education study programme curricula as the traditional academic print world is changed. Students involved in the Teachers' Education study programme at University are using Web conducting their learning process. Academic writing as a part of learning process at University is based on cognition and activity. We propose to define the training of students' academic writing as a learning process transforming the student's knowledge in unity of two positions: curricular academic writing and informal academic writing. We propose three criteria towards the students' academic writing as heuristics, self-dependence and collaboration. How can we help our students to promote academic writing by using the digital environment? How can we help them differentiate between the appropriate and inappropriate use of information found on the Web and understand what plagiarism is and how is to be avoided?
