2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin

Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2. AGENDA:
• INTRODUCTION
• DATA DEFINATION LAMGUAGE
• TYPES OF DDL AUTHORIZATION
• DDL IN DATA MANIPULATION
• DDL IN RELATIONAL DATABASE
• CONCLUSION
3. INTRODUCTION
• A collection of interrelated data and set of program to access the
data.
• To provide a way to store and retrieve database information
• To keep information about all customers a saving accounts.
• To allow users to manipulate the information.
• File processing system.
4. DATA DEFINITION LANGUAGE
• The database schema by set of definition expressed by a special
language is called data definition language.
• The storage structured and access methods used by the database
system in DDL , is called data storage and definition language.
• The output of the DDL list, placed in the data dictionary which
contains meta data(data about data).
5. TYPES OF DDL AUTHORIZATION
• There are four types of authorization in data definition language.
READ AUTHORIZATION: allow only reading.
INSERT AUTHORIZATION: allow only insertion of new data.
UPDATE AUTHORIZATION: allow modification but not deletion.
DELETE AUTHORIZATION: allow deletion of data.
6. DDL IN DATA MANIPULATION
• Data manipulation language that enables users to access and manipulate data
by the appropriate data model.
• Data definition language allow one to define tables, integretity constrains,
assertions etc.
• There are many types of accesses in data manipulation language.
• Data manipulation language is the mostly in the DDL concept.
• SYNTAX: >create table account(accno char(10), balance integer);
7. DDL IN RELATIONAL DATABASE
• Relational database uses a collection of tables to represent both data
and relationships among those data.
• There are four parts of the relational database,
Tables
Data manipulation language
Data definition language
Database access from application program
8. CONCLUSION
• Data definition language is a standard for commands that define
the different structures in a database
• Data definition language statements create, modify, and remove
database objects such as tables, indexes, and users.
• Common data definition language statements are
CREATE,ALTER, and DROP.
