The Science of Learning: implications for modern teachingDerek Wenmoth
Keynote presentation to the Educational Leaders hui Kōkiritia Marautanga held in Auckland on 26 June 2024. Provides a high level overview of the history and development of the science of learning, and implications for the design of learning in our modern schools and classrooms.
Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

50 Extraordinary AWS CloudWatch Interview
Questions & Answers
AWS CloudWatch Interview Questions
Amazon Web Services (AWS) is a cloud computing service provided by Amazon.
You can easily create, test, launch, and maintain your apps & services on Amazon
Web Services. Some important things to know about AWS CloudWatch:
AWS CloudWatch is a service that keeps an eye on the AWS resources you use and the
AWS apps you run. It can automatically set alarms, track and collect metrics, and respond
to changes in your AWS resources.
It is a management service tool designed for system architects, developers, and
administrators to monitor their Amazon web services applications
1. What is AWS CloudWatch?
Amazon Web Services (AWS) CloudWatch is a monitoring service for AWS resources
and the applications you run on the cloud platform. It provides data and operational
insights for resources such as Amazon Elastic Compute Cloud (EC2) instances, Amazon
DynamoDB tables, and Amazon RDS DB instances, as well as custom metrics generated
by your applications and services.
CloudWatch can monitor resources in real-time and send alerts when thresholds are
breached. It also provides a range of visualization and analysis tools to help you
understand and optimize your resources and applications.
2. Is CloudWatch free to use?
Yes, Amazon CloudWatch is available for free to use. Metrics for the majority of AWS
Services (EC2, S3, Kinesis, etc.) are sent directly and for free to CloudWatch. These
constraints on the free tier should be sufficient for many apps.
3. How do I use CloudWatch?
Create IAM users or roles that give the agent access to the server’s metrics and,
optionally, AWS Systems Manager integration. Get the agent bundle now. Specify the
metrics you wish to gather in the CloudWatch agent configuration file. Install the agent
on your servers, then launch it.
4. What is the difference between CloudWatch and CloudTrail?
AWS CloudWatch and AWS CloudTrail are both services provided by Amazon Web
Services (AWS), but they serve different purposes.
2. www.datacademy.ai
Knowledge world
AWS CloudWatch is a monitoring service for AWS resources and the applications you
run on the cloud platform. It provides real-time data and operational insights for
resources such as Amazon Elastic Compute Cloud (EC2) instances, Amazon DynamoDB
tables, and Amazon RDS DB instances, as well as custom metrics generated by your
applications and services. CloudWatch can monitor resources in real-time and send alerts
when thresholds are breached. It also provides a range of visualization and analysis tools
to help you understand and optimize your resources and applications.
On the other hand, AWS CloudTrail is a service that enables you to track changes to your
AWS resources and to troubleshoot issues. It provides a record of all API calls made to
your AWS accounts, including the request parameters, response elements, and any errors
that occurred. CloudTrail can be used to monitor and secure your AWS infrastructure, as
well as to ensure compliance with internal policies and regulations.
5. What is a CloudWatch Alarm?
The new CloudWatch Alarms feature helps in monitoring CloudWatch metrics and
receiving notifications when they fall outside of the levels (high or low thresholds) you
set. Each metric can have multiple Alarms, each with its own set of actions.
The status of a CloudWatch Alarm is always one of three: OK, ALARM, or
INSUFFICIENT DATA. The Monitor is in the OK state whenever the metric is within
the acceptable range that you have defined. When it reaches a certain threshold, it enters
the ALARM state. The monitor enters the INSUFFICIENT DATA state when the data
required to make the decision is missing or incomplete.
6. How does Amazon CloudWatch work?
Your applications and infrastructure resources may be monitored and managed using
Amazon CloudWatch, which offers a unified solution. It is a web service you can use to
gather metrics, understand your application and the infrastructure supporting it, and
automatically respond to changes. You can monitor AWS resources with Amazon
CloudWatch and adjust the monitoring to your company’s requirements.
7. List different types of Cloud Services
Cloud services can be broadly classified into three categories: infrastructure as a service
(IaaS), platform as a service (PaaS), and software as a service (SaaS). Here is a brief
overview of each type of cloud service:
1. Infrastructure as a Service (IaaS): IaaS is a type of cloud service that provides
infrastructure resources such as computing, storage, and networking on a pay-as-
you-go basis. IaaS providers typically offer a range of options for configuring and
customizing these resources to meet the needs of your applications and workloads.
3. www.datacademy.ai
Knowledge world
Examples of IaaS providers include Amazon Web Services (AWS), Microsoft
Azure, and Google Cloud Platform (GCP).
2. Platform as a Service (PaaS): PaaS is a type of cloud service that provides a
platform for developing, deploying, and managing applications on the cloud. PaaS
providers typically offer a range of tools and resources for building, testing, and
deploying applications, as well as services for managing and scaling them.
Examples of PaaS providers include AWS Elastic Beanstalk, Microsoft Azure App
Service, and Google App Engine.
3. Software as a Service (SaaS): SaaS is a type of cloud service that provides software
applications that can be accessed over the internet. SaaS providers typically offer
a range of applications that can be used for tasks such as productivity,
collaboration, customer relationship management, and more. Examples of SaaS
providers include Microsoft Office 365, Salesforce, and Google G Suite.
There are many other types of cloud services available, and the specific offerings can
vary significantly among different providers. Some other examples of cloud services
include data as a service (DaaS), security as a service (SECaaS), and communication as
a service (CaaS)
8. How can I monitor my AWS resources in near real-time?
You may gather and keep track of measurements in a timeframe that is close to real-time
by using AWS CloudWatch. The information regarding its metrics is kept as time-series
data points. In addition, each data point in a time series is accompanied by a timestamp
as well as a unit of measurement.
9. How to delete alarms in AWS CloudWatch Console?
Use the following command to delete the alarms in AWS CloudWatch Console:
aws cloudwatch delete-alarms --region us-east-2 --alarm-names ...
10. What is Power User Access in AWS?
The owner of the AWS resources will be comparable to an administrator user. It can
grant access to other users for the AWS resources that add, delete, change, or inspect the
resources. Administrator access is provided with Power User Access but without the
ability to control users and permissions.
In other words, a user who has Power User Access can create, delete, change, or view
the resources but cannot allow other users access.

6. www.datacademy.ai
Knowledge world
17. How to get additional lines of context in a CloudWatch Insights query?
In AWS CloudWatch Insights, you can use the context function to retrieve additional
lines of context around a specific event in your log data. The context function takes two
arguments: the number of lines of context to retrieve before and after the event.
Here is an example of a CloudWatch Insights query that retrieves three lines of context
before and after each event:
fields @timestamp, @message
| sort @timestamp desc
| limit 20
| context 3 3
This query will display the timestamp and message fields for the most recent 20 events
in your log data, sorted in descending order by timestamp. It will also display three lines
of context before and after each event.
You can adjust the number of lines of context by changing the arguments of
the context function. For example, to retrieve five lines of context before and after each
event, you can use the following query:
fields @timestamp, @message
| sort @timestamp desc
| limit 20

Visualizing Metrics and Logs
Event Management
Integration with other AWS Services like Lambda or SNS to automate actions based on
Alarm Triggers
CloudWatch Agent for real-time metric collection on on-premise instances.
CloudWatch Synthetics for monitoring of end-to-end experience of your application with
canaries and browser scripting And many more depending on the specific service and
use case you are trying to monitor and automate.
What is the use of CloudWatch in AWS?
Amazon CloudWatch is a monitoring service for AWS resources and the applications
that you run on AWS. It allows you to collect and track metrics, collect and monitor log
files, and set alarms. Some of the main uses of CloudWatch include:
Resource monitoring: CloudWatch allows you to monitor the performance and health of
your AWS resources, such as Amazon EC2 instances, Amazon RDS DB instances, and
Elastic Block Store (EBS) volumes.
Application monitoring: CloudWatch allows you to monitor the performance and health

of your applications running on AWS, by collecting custom metrics from your
application and services.
Alarm management: CloudWatch allows you to set alarms that can automatically react
to any threshold you specify. When an alarm is triggered, you can have CloudWatch send
notifications or automatically make changes to the resources being monitored.
Logging: CloudWatch allows you to monitor log files from your applications and AWS
resources. CloudWatch Logs lets you monitor, store, and access your log files from
Amazon EC2 instances, AWS CloudTrail, and other resources. This allows you to
troubleshoot issues more easily and perform analysis on your logs.
Dashboard: Custom Dashboards to get a comprehensive view of all the metrics and logs
of your resources and applications, in a single place.
Automation : Using CloudWatch event and alarms, automate actions based on certain
triggers, like scaling up or down EC2 instances, or sending SNS notifications.

The service is very useful for monitoring, troubleshooting and automation of your AWS
infrastructure and applications, allowing you to detect and fix issues quickly, and also
optimize cost and performance.
What are the 3 states of the CloudWatch metric alarm?
In Amazon CloudWatch, a metric alarm can have one of the following three states:
OK: This state indicates that the metric is within the specified thresholds. If an alarm is
in the OK state, no action is taken.
ALARM: This state indicates that the metric has breached one or more of the specified
thresholds. When an alarm is in the ALARM state, CloudWatch can take one or more
actions, such as sending a notification or taking an automated action.
INSUFFICIENT_DATA: This state indicates that CloudWatch has not received enough
data points to determine the alarm state. This state can occur if an alarm is created or
updated but the metric data is not yet available, or if the alarm has just been deleted.
Alarms are transitioned from OK to ALARM state and vice versa if the alarm’s threshold
is breached, if an alarm is deleted or if an alarm is updated.
CloudWatch Alarm is a powerful feature, that can help you to monitor your resources
and applications more effectively, proactively address potential issues, and automate
actions based on certain triggers. By combining with SNS, you can notify your teams,
on-call, or even send automated actions like scaling up instances. Alarms are an essential
part of your infrastructure and can save you time, money and prevent outages.
