ELO (Electronic Language Organizer) is an authoring system for the production and assembly of Open Educational Resources (OERs), aimed especially at language teaching.

With ELO you can create different types of activities, based on the assembly of existing REAs, already available in the repository, or created by the teacher. Examples of REAs:

Eclipse: Displays texts to be reconstructed by the student. Ideal for exploring standardized forms of language such as situated dialogues, proverbs, abstracts, etc.

Sequence: Displays unordered segments. Ideal for exploring and teaching how words, sentences and paragraphs are connected in text.

Cloze: Creates gapped texts. The gap can be a word, part of a word (suffix, prefix, etc.), or a multi-word expression. Ideal for working with definitions, grammatical issues, description of characters, dialogues and keywords.

Memory: : Creates a memory game. It can be used not only for the teaching of vocabulary, but relationships (phrasal, cause and consequence, appropriate verb and object, etc.).

Quiz: Creates multiple-choice and short answer items. Multiple choice allows for general and specific feedback for each alternative. Short answer items display questions to be answered by the students, with different kinds of feedback and a sophisticated analysis of the open answer provided by the student.

Composer: Allows for free writing by the student.

Organizer: Relates the parts with the whole, creating a relationship between hyponyms (the parts) with its hypernym (the whole).

Hypertext. Used for the production of multimodal pages.

Eclipse, Sequence, Cloze, Memory, Organizer and Quiz are interactive OERs. Composer and Hypeertext are expository OERs. In all of them you can insert verbal text, audio and video


ELO encourages the publication of OERs, providing site space with open access to teachers, students and schools.

Some suggestions for producing the activities:

Theme. Each activity should incorporate learning objects, having a well-defined single theme and involving some aspect of language teaching.

Persistence. Topics of momentary interest, which soon expire, should be avoided. The same caveat holds for extremely localized issues.

Interactivity. The activity must provide immediate interactivity with the user. Long texts, followed by questions, are considered unsuitable for interactive activities.

Length. The limit for the length of each activity to be done by the student should be around 30 minutes, with a maximum variation between 15 and 45 minutes, considering slow and advanced students.

Copyright. Copyright issues for the use of text, images, audio and videos are the entire responsibility of the author. All sources must be referenced. Authorship for the activities prepared by the teacher are automatically guaranteed by the system, using Creative Commons license CC BY NC.
