The document discusses translating verbal phrases into algebraic expressions and using verbal models to write mathematical equations and inequalities. It provides examples of common verbal phrases involving numbers, operations, and variables and their corresponding algebraic translations. It also outlines a three-step process for writing a mathematical model from a word problem: 1) write a verbal model, 2) assign labels, and 3) write the algebraic model. Finally, it demonstrates this process with a sample word problem about the cost of dim sum plates after tax.
Desafio das Estimativas - Utilizando métricas científicas com KanbanBruno Brandes
Na maioria das vezes, estimativas são feitas para saber o Retorno Sobre Investimento (ROI). Nestes slides compartilho minha jornada até aqui, abordando como abandonar timeboxes e estimativas com a implantação do Kanban. Apresento como isso possibilitou o alcance a dados científicos do processo, deixando o fluxo de trabalho mais previsível e mais ágil, aumentando valor e qualidade das entregas.
Both seasoned analysts and AR professionals love a debate – no doubt that’s why they work in this industry! Conversations about the nature of influence, analysts versus bloggers, the role of analysts in buying decisions, whether independent analysts can truly ever be independent will no doubt run and run. They can make it hard for newcomers however, who could be forgiven for wondering what the fuss is all about.
With this in mind, the IIAR is releasing a primer on the analyst industry. It is deliberately, unapologetically designed for those with no previous experience of working with analysts – while it does touch on such debates, it leaves any cans of worms tightly closed. Rather, it covers:
• The kinds of work analysts might be involved in across the working day.
• A definition of analysts, differentiating them from financial analysts and market researchers.
• An overview of firms, types, products and services across the market as a whole.
• Services offered by different kinds of analyst firms, be they “buy side” or “sell side”.
The main question the paper aims to answer is why analysts exist at all – after all, no other industry has them in such numbers. To give away the punchline, the paper draws the conclusion that they bring necessary clarity to the still-nascent sector we call the Information and Communications Technology. If you are new to Analyst Relations or the industry and would like to learn more about it, or if you want an overview to help explain the analyst industry to others, this paper is for you.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
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.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

The sum of six and a number 6 + x
The sum of six and a number is 6 + x =
The sum of six and a number is twelve. 6 + x = 12
In this sentence, “is” says that
one quantity is equal to one
another.
In this sentence, the words
“is less than” indicate an
inequality.
The sum of six and a number
is less than twelve.
6 + x < 12
number is twelve. 6 + x = 12

twelve.
6 + x < 12
4. USING A VERBAL MODEL
Use three steps to write a mathematical model.

VERBAL MODEL.
ASSIGN
LABELS.
WRITE AN
ALGEBRAIC MODEL.
Writing algebraic expressions, equations, or inequalities
that represent real-life situations is called modeling.
The expression, equation, or inequality is a
mathematical model.
5. Writing an Algebraic Model
You and three friends are having a dim sum lunch at a Chinese
restaurant that charges $2 per plate. You order lots of plates.
The waiter gives you a bill for $25.20, which includes tax of
$1.20. Use mental math to solve the equation for how many
plates your group ordered.
Understand the problem situation
before you begin. For example,
notice that tax is added after the total
cost of the dim sum plates is figured.

Writing an Algebraic Model
Ask yourself what you need to know to solve the
problem. Then write a verbal model that will give
you what you need to know.
Assign labels to each part of your verbal problem.
Use the labels to write an algebraic model based on
your verbal model.
Solve the algebraic model and answer the original
question.

8. Using a Verbal Model
JET PILOT A jet pilot is flying from Los Angeles, CA to Chicago, IL at
a speed of 500 miles per hour. When the plane is 600 miles from
Chicago, an air traffic controller tells the pilot that it will be 2 hours
before the plane can get clearance to land. The pilot knows the speed of
the jet must be greater then 322 miles per hour or the jet could stall.
a. At what speed would the jet have to fly to arrive in Chicago in 2 hours?
Is it reasonable for the pilot to fly
directly to Chicago at the reduced
speed from part (a) or must the
pilot take some other action?

SOLUTION
To arrive in 2 hours, the pilot would have to slow the jet down to 300 miles per hour.
You can use the formula (rate)(time) = (distance) to write a verbal model.
10. Using a Verbal Model
It is not reasonable for the pilot to
fly at 300 miles per hour, because
the jet could stall. The pilot should
take some other action, such as
circling in a holding pattern, to use
some of the time.
Is it reasonable for the pilot to fly directly to Chicago at 300
miles per hour or must the pilot take some other action?
