Imagine a future where humans are unable to access the data, literature, art, photographs, discoveries, and vital records of previous generations. That bleak future may be on the horizon! Learn how our fragile, rapidly-obsolete systems of storing data could lead to a digital dark age. This video comes with discussion questions.
This activity provides several ways to introduce students to databases, with follow-up lesson extensions for increasing database understanding.
This report gives details of a series of computing lessons designed to relate fundamental concepts of database use and design to children in Primary and Secondary Education (ages of 6 to 16). The skills and concepts developed in these lessons begin at a very simple level but progress to cover abstract concepts such as Relational Databases. The series has been aligned to match the scope, range and targets recommended in the Computing At Schools document A Curriculum for Computing.
This activity concludes with a “plugged-in” activity using a database system. The Digital Schoolhouse Database Detectives lesson is aimed at Key Stage 2 pupils and based on the book Certain Death by Tanya Landman. Before completing the series of database unplugged activities, the class teacher is encouraged to read the book (except the last chapter) and complete a series of encryption activities loosely based on the book, the answers providing pupils with the clues to question the database and identify the murderer.
Pupils use cloud computing technology e.g. Google Documents: Spreadsheets, to collaboratively input data about the suspects from profile cards based on the book. Pupils then perform verification on their neighbor’s data entry before downloading the spreadsheet and importing it into Microsoft Access. After importing the data, pupils first use the filter tool to solve the murder using the answers from the numeracy challenges, then create a report for the Court based on a query identifying the murderer.
Data is stored differently depending on its type. Numbers are stored as integers or real numbers, text as string or characters. Lists of the same type of data can be stored in an array.
This webpage examines integer data, real or float data, characters, strings, boolean values, and arrays.
