QUESTION ONE

(a) Type the following text using a word processor, font size 12’, line spacing 1 1/2 and save it as ACM1. (20mks)

Congress Endorses Computer Science Education as Driver of Innovation, Economic

Growth

AC (1 0/21/0 9,)

ACM and several computing community partners commend the U.S. I-House of Representatives

passage of a resolution to improve the visibility of computer science as a transforming industry

that propels technology innovation and improves economic productivity. The House resolution

designates the week of December 7 as ‘National Computer Science Education Week’ and calls

on educators and policymakers to improve computer science learning at all education levels and to encourage increased participation in computer science.

ACM is working with Microsoft. Google, Intel. the Computer Science Teachers Association (CSTA), the NationalCenter for Women & Information Technology (NC WIT), and the Computing Research Association to improve awareness that computer science education is a national priority. “National Computer Science Education Week will help us draw attention to the need for an educational system that values computer science as a discipline and provides students with critical thinking skills and career opportunities,” says ACM Education Policy Committee chairBobby Schnabel, dean of the School of Informatics at IndianaUniversity.

CSTA executive director Chris Stephenson notes the vital role that computing plays in people’s daily lives, and stresses the urgency of building a strong computing workforce. “We need to expose K- 12 students to computer science concepts to help them gain critical 21st century skills and knowledge. and we’re grateful for Congress’ recognition of this need as a national priority,” Stephenson says. NCWI CEO and co-founder Lucy Sanders says the annual commemoration of National Computer Science Education Week can strengthen efforts to inform students, teachers, parents, and the public about how computer science enables innovation in all science, technology, engineering, and mathematics fields and creates economic opportunities.

REQUIRED

(a) (i) Format the heading as follows: Uppercase, size 16’, double underlined. (3mks)
