Greetings, Attendance check, hometask check.

1. Students watch the video and take notes of the important points.

2. After the video, each student in the class has to tell 1 fact from the video.

3. The fact should not be repeated twice.

After watching the video, students will understand that the lesson is about encoding bitmap graphics.

Familiarity with the topic of the lesson, setting the objectives, discussion of the marking criteria: teacher introduces the students to the topic and objectives of the lesson, conducts a discussion with the students of marking criteria.  Teacher explains how bitmaps can be represented in binary.

(I)  Teacher suggests students to copy previously prepared “Bitmap_Images” file from the network to their workspace, then by using the image from the left side fill-in by binary values the right side of given table. (1 = image is drawn in cell 0 = empty field)

Task 1.

After filling the cells students has to work through the next image «Final 8 x 8 image», where all 1’s are black, and 0’s are white.

What is wrong with quality of image?

Task 2.

Students  has to choose the next image and repeat all steps from previous task to fill 16x16 image. Then, has to check final version of 16-bit image on next slide.

What happened with quality of image in comparison with 8x8?

(Teacher FA through a series of suggestive / supportive questions)

Marking criteria:

Encodes bitmap image into binary code (1 & 0)

Descriptor:

- Converts 8x8 size black and white image into binary code;

- Converts 16x16 size black and white image into binary code.

Skill: Implementation of knowledge

(D) Teacher demonstrates how colored images are sent, and how different colors are encoded.

Task 3.

Students will use a wider range of numbers to create a color image and use numbers from 0 to 3 inclusive. You need to make your own image by using these colors.

(Teacher FA through a series of suggestive / supportive questions)

Marking criteria:

Encodes bitmap image into binary code (1 & 0)

Descriptor: Converts colored image into binary code

Skill: Implementation of knowledge

(I, F) The teacher offers students to solve several problems:

1. Modern monitor allows you to receive on the screen 2048 different colors. How many bits of memory takes 1 pixel?

–  One pixel encodes by using 0’s and 1’s.

N = 2ⁱ, N- number of colors displayed on the screen, i – color depth.

Given that N=2048

Find i

–  2i =2048, i=11

–  i=log2 2048 =11 bit

2. Calculate the required amount of video memory in graphics mode 1024 x 768 pixels and a color depth of 16 bits per pixel

Screen pixels’ size:

1024 • 768 = 786 432

required amount of video memory:

16 bit • 786432 = 12 582 912 bit = 1 572 864 byte= 1 536 Kbyte = 1,5 Mbyte.

–  Let’s represent formula of calculation amount of video memory in graphical image: V=i*X*Y

3. Calculate the required amount of video memory in graphics mode 800 x 600 pixels and a color depth of 24 bits per pixel.

Screen pixels’ size: 800 • 600 = 480 000. required amount of video memory:

24 bit • 480 000 = 11 520 000 bit = 1 440 000 byte =

= 1406,25 Kbyte = 1,37 Mbyte.

(FA through self-marking, students evaluate their knowledge, based on the material studied)

Marking criteria:

Finds amount of video memory

Skill: Implementation of knowledge

Values – lifelong learning, collaboration, transparency and academic integrity, work and creativity will be carried out through discussion and practical work, as well as indicating sources of data, when creating and evaluating a project

through brainstorm  “Linoit”

Hometask

Lesson Reflection

Linoit service can perform the role of online board, through which canvases with sheets of stickers are created. Teacher invites students to answer questions using stickers.

Feedback

Return to the objectives of the lesson, determining whether all goals are achieved.

Task 1.  Each point of the monitor screen (pixel) is assigned four bits, which will display n colors.

Task 2. The video memory size is 4 MB, the bit depth is 24, the display resolution is 640 x 480. What is the maximum number of pages that can be used under these conditions?

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check learners’ learning?

Health and safety check
ICT links

Differentiation can be expressed in the selection of tasks, in the expected result from a particular student, in providing individual support to the student, in selecting the educational material and resources, taking into account the individual abilities of the students (Theory of Multiple Intelligence by Gardner). Differentiation can be used at any stage of the lesson, taking into account the rational use of time.

Use this section to record the methods that you will use to assess what the students have learned during the lesson.

Health and safety check links.

Used active exercises.

Items applied from the Safety Rules in this lesson.

Reflection
