A CONTENT AND LANGUAGE INTEGRATED APPROACH"

OBJECTIVES  (2/2)

Secondary Objective (Language-Based)

Students will know important aspects of language learning based on their own real-time experience of SLA and the examples and activities proposed by the teacher, related to feedback systems. 

BASIC CONCEPTS: MODELS

BASIC CONCEPTS: INPUT/OUTPUT MODELS

• Models allow us to reason about a system and make predictions about how a system will behave.
  
• The signals represent the interaction of the system with its environment (inputs and outputs).
  

ILLUSTRATIVE EXAMPLE: LANGUAGE MODELS

• "Second language (L2) is considered as a separate and qualitatively different system from first language (L1)". 

• "In adult users, L1 is considered as a largely deterministic or stable-state form of language".  
• "L2 is considered as a nonlinear dynamic system.  It is used with relatively high degree of unpredictability".  (Sumi, 2003)

ILLUSTRATIVE EXAMPLE: SLA Model

KEY IDEA 2

• Dynamical Systems are essential to analyze Real-World Applications. “Mother Language (L1) and Second Language (L2) are systems with very different dynamics  ” 

BASIC CONCEPTS: FEEDBACK SYSTEMS

BASIC CONCEPTS: FEEDBACK SYSTEM

"Feedback is a central feature of life"

BASIC CONCEPTS: CONTROL SYSTEM

The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is subtracted from the desired value to create the error signal,

SIMPLE FORMS OF FEEDBACK: On-Off Control

DISCUSSION: L1/L2 Control in a CLIL Classroom
