Tips For Collecting Data During Home ABA Therapy

 For parents conducting intensive ABA or Applied Behavior Analysis therapy at home, collecting and tracking data can seem like a daunting task.  Some parents feel that they need to keep rigorous data in regards to every question to a degree that it hampers their ability to teach effectively, while some parents feel that they can rely on memory to track their child's progress and note both impairments and improvements.  The truth is that data collection is a delicate balance between ensuring that progress is properly noted without getting so wrapped up in details that the lesson suffers.  What follows are some basic tips for collecting data.

It should first be noted that parents are encouraged to use data collection sheets.  Professionally designed to offer task analysis as well as the creation of easy to read graphs, data collection sheets simplify analyzing your child's progress with ABA therapy.  For parents who opt to create their own data records, however, there are some tips to simplify and streamline the process.  It is recommended to record data for separate sections and skills on separate sheets of paper and to document results only at the end of the lesson.
 
One tip many parents find helpful is to take a task such as getting dressed and break it down into smaller sections, such as choosing clothes, putting on underwear, putting on pants, putting on shirt, putting on sock, putting on shoes, putting pajamas in hamper, etc.  When each step is outlined, it becomes easy to outline which steps were taken without prompt and which required prompting.  This helps to outline trends and areas that need more work.  The same theory can apply for any activity, including things such as shape or color recognition, with notes being taken of shapes or colors recognized alone and those requiring a hint or prompt.  It is important to count only the child's first response and to be truthful in your data recording, as counting partial answers can skew data and harm your progress in the long run.
 
In short, data collection can be a relatively simple process even though it is highly important.  While professional collection sheets are recommended, many parents find success using their own data collection methods.  Applied Behavior Analysis relies heavily on the assessment of the data that is collected from each lesson, but as long as the proper data is recorded and the proper points are stressed and worked on, ABA is designed to help your child function as normally as possible.

Collecting Data With Web Scrapers

There is a large amount of data available only through websites. However, as many people have found out, trying to copy data into a usable database or spreadsheet directly out of a website can be a tiring process. Data entry from internet sources can quickly become cost prohibitive as the required hours add up. Clearly, an automated method for collating information from HTML-based sites can offer huge management cost savings.

Web scrapers are programs that are able to aggregate information from the internet. They are capable of navigating the web, assessing the contents of a site, and then pulling data points and placing them into a structured, working database or spreadsheet. Many companies and services will use programs to web scrape, such as comparing prices, performing online research, or tracking changes to online content.

Data Collection Tools

Let's take a look at how web scrapers can aid data collection and management for a variety of purposes.

Improving On Manual Entry Methods

Using a computer's copy and paste function or simply typing text from a site is extremely inefficient and costly. Web scrapers are able to navigate through a series of websites, make decisions on what is important data, and then copy the info into a structured database, spreadsheet, or other program. Software packages include the ability to record macros by having a user perform a routine once and then have the computer remember and automate those actions. Every user can effectively act as their own programmer to expand the capabilities to process websites. These applications can also interface with databases in order to automatically manage information as it is pulled from a website.

Aggregating Information

There are a number of instances where material stored in websites can be manipulated and stored. For example, a clothing company that is looking to bring their line of apparel to retailers can go online for the contact information of retailers in their area and then present that information to sales personnel to generate leads. Many businesses can perform market research on prices and product availability by analyzing online catalogues.

Data Management

Managing figures and numbers is best done through spreadsheets and databases; however, information on a website formatted with HTML is not readily accessible for such purposes. While websites are excellent for displaying facts and figures, they fall short when they need to be analyzed, sorted, or otherwise manipulated. Ultimately, web scrapers are able to take the output that is intended for display to a person and change it to numbers that can be used by a computer. Furthermore, by automating this process with software applications and macros, entry costs are severely reduced.

This type of data management is also effective at merging different information sources. If a company were to purchase research or statistical information, it could be scraped in order to format the information into a database. This is also highly effective at taking a legacy system's contents and incorporating them into today's systems.

Overall, a web scraper is a cost effective user tool for data manipulation and management.
