The development of on-line technologies in the last years provided us with a possibility for the efficient video teaching in e- or blended- chemistry learning [1–10]. In this publication we reviewed materials which are available on the YouTube or specialist educational platforms [14–38]. The analysis indicated that on-line teaching has progressed rapidly over recent years (Fig. 1, Fig. 2). This refers also to chemistry. In particular we focused on organic chemistry. The on-line aided teaching of experimental chemistry can also support the traditional courses [9] Our experience indicated that even in bench chemistry on-line teaching can significantly improve the performance of the students. The e-chem project of the educational platform, started for the chemistry students in the University of Silesia in 2005 [15], is an example of the blended chemical teaching that was partially published on the YouTube website (Tab. 2). A number of other chemistry materials are available on YouTube. Some chemistry courses are also available directly at the websites of the universities while the Inducate, Skillup or Coursea [39–42] are examples of the websites that provide further useful addresses for chemistry on-line teaching. A concept of massive open on-line courses (MOCC) [43, 44] that appeared recently inspired several projects of commercial platforms for e-learning, providing a potential bases for the global teaching. The Coursera, Udacity, EdX, Canvas Network are examples of the complex educational portals for MOCCs. At the same time the important universities are vigorously playing in this area in a way to global university. At the moment the MOCC chemistry available was reviewed (Tab. 3). In summary, the development of the on-line technologies provides a possibility for the efficient blended learning based video-aided chemistry teaching. In our opinion this potential is currently controlled not by technical limitations but rather by psychology barrier and formal regulations in local educational law. However, these problems will certainly be solved with the increasing availability of the on-line courses that could be supported by additional real lab classes and/or certified by exams. Global university will be of course a strong competition for a traditional education. On the other hand this also means chemical on-line courses will be better and better developed on the basis on the available on-line technologies. Eventually, this competition will also improve a quality of the traditional chemical education.

Nowadays dynamic development of electronically supported teaching and learning methods exerts significant influence on modern teaching of chemistry. This resulted in E-chemistry: a combination of computer science and chemistry which covers many fields of knowledge, from education of chemistry and scientific information access to computer modeling of chemical compounds and reactions (Fig. 2). At present, majority of universities resigns from publication of printed materials for students and provide access to teaching materials published on-line. Current electronic systems offer a great variety of workspaces and channels to facilitate distribution of information to students, enhancement of face-to-face courses, e-books creation, preparation of teaching materials, tests and electronic exams, management of electronic lessons, or even creation of virtual chemistry laboratories. For instance, chemistry students have an on-line access to the chemical databases, publications and lots of software for chemistry. An e-learning system gives a possibility of mixing various kinds of objects such as text, images, animations, quizzes, interactive applications or links to other web sites. Furthermore, adaptive courses based on cognitive trials, learning styles, and relationships between learners can enrich each other, enabling the system to provide the learners with courses which fit their needs more accurately. There is a number of acronyms used in e-learning, often with similar meanings. Published materials and users’ activities are managed by a set of dedicated computer programs called Virtual Learning Environment (VLE). An e-learning system together with a VLE can have one of the following names: Course Management System (CMS), Learning Content Management System (LCMS), Learning Management System (LMS), Managed Learning Environment (MLE), Learning Support System (LSS) or Learning Platform (LP). E-learning systems base on a computer network and provide an on-line access to educational materials, therefore e-learning can also be called Online or Mobile Education [1]. In this paper the author shows an overview of e-learning and then a specific application of e-learning of chemistry used at the Department of Chemistry at Wrocław University of Technology [2, 3, 4], presenting some practical solutions applied.
