Understanding Journalistic Texts

Journalistic texts, aimed at informing about current events and topics of general interest, are included in the so-called mass media. However, informing is not their sole purpose, as they also incorporate reviews, opinions, or criticisms about certain behaviors, events, and attitudes.

These texts possess very heterogeneous characteristics, offering information on national, international, local, sports, cultural, educational, and economic topics. They are fundamentally divided into sections, accommodating the expression of opinion.

Both the sender (the media outlet, though the text is written by a journalist) and the receiver (the audience) are collective entities. The relationship between sender and receiver is... Continue reading "Journalistic Communication: Functions, Language, and Characteristics" »

Effective Approaches to Mathematics Education

Concrete bases: Turning math into something concrete involves creating recognizable contexts to which children can assign their own meanings. To achieve progress in levels, students must have at their disposal models and tools to establish a link between informal and formal mathematics.

The Importance of Models and Materials

• Moments for reflection: The teacher must find the right time to include reflection on the specific kind of mathematics being taught.
• Interactive math lessons: Interaction should be natural in a mathematics classroom.
• Weaving the threads of learning: Teachers should base their teaching on real-world situations (horizontal mathematization). Conversely, vertical mathematization allows
