UNED Group in Learning Technologies and Cooperative Systems

PALO is a proposal of to describe and design learning content and learning environments at a high level of abstraction.
PALO language is an open proposal of EML developed at the Department of Languages and Computer Systems at UNED University. Educative content written in PALO has been tested since academic years 98/99 at the SENSEI educative web site of the Dept. of Languages and Computer Systems of UNED University.
PALO files are processed using a PALO Compiler called paloc. The compiler is invoked and configured from an visual interface developed in Tk/Tcl. |
Purpose
PALO has been designed to be a technology-independent representation of a learning resource, thus allowing educative content interchange, interoperability, maintainability and reusability. A PALO description of a learning content (a *.palo file) can be turned into a variety of learning scenarios (each one built using an specific delivery format) via a compiling process. |

PALO is based on a reference framework to design educative content based in 5 levels of abstraction. Each level identifies a certain group of related components or elements of a learning resource. The language allows to define teaching strategies by mean of the definition of specific DTD's called instructional templates. These templates are a general type of PALO document that specially suits for a given instructional or teaching purpose.
The PALO approach considers the following levels or layers:- Layer 1: Educational Content. This level describes the elements of the information model referred to the insertion of educational content.
- Layer 2: Activity and cooperative model. This layer provides a way to describe a collaborative learning activity along with its working community and a set of features, tools and resources. Actual PALO implementation considers activities as individual tasks.
- Layer 3: Structure. Structure level provides hierarchical decomposition of the learning environment.
- Layer 4: Sequencing and Scheduling. This level considers time restrictions and pedagogical dependencies associated to certain components of the learning environment.
- Layer 5: Management. This level considers time restrictions and pedagogical dependencies associated to certain components of the learning environment.
