Language objectives
|
Student is able to describe the String type used in C# programming language. For instance, to work with strings one have to include System namespace reference to program’s code . Also, student can justify the purpose of function and procedure Vocabulary and terminology specific to the subject: string, string operators, comparing stings, symbols of string Useful expressions for dialogs and letters: Well, the variable of string type is created by … . For example, assignment of some value to string variable … . Obviously, the stings used for the wide variety of cases like … .

Task 1 Action: practice Purpose: introducing to declaration and initialization of strings in various ways Description:
Evaluation:
Task 2 Action: write a program Purpose: learn how to concatenate two strings Description:
Evaluation:
Differentiation: The students who finish earlier have to develop the program by adding the new sentence ‘So, today I won’t go for swimming.’. Students must use a loop to append a single word each time, so procedure is called several times. Feedback: Teacher makes comments or correction when necessary
Summary Questions: What is the string in C#? How to declare string variable? How to initialize string variable? |

Differentiation - how do you plan to provide more support? What tasks do you plan to put before more able learners? |
Evaluation - how do you plan to check the level of mastering the material by learners? |

Дифференциация может быть выражена в подборе заданий, в ожидаемом результате от конкретного ученика, в оказании индивидуальной поддержки учащемуся, в подборе учебного материала и ресурсов с учетом индивидуальных способностей учащихся (Теория множественного интеллекта по Гарднеру). Дифференциация может быть использована на любом этапе урока с учетом рационального использования времени. |

Reflection on the lesson
Were the goals of lesson/ learning objectives realistic? Have all the students reached the LO? If not, why? Is the differentiation done correctly in the lesson? Were the time stages of the lesson sustained? What were the deviations from the lesson plan and why? |

Appendix 1
(handout 1)
Declaring and Initializing Strings
// Declare without initializing.
string message1;
// Initialize to null.
string message2 = null;
// Initialize as an empty string.
// Use the Empty constant instead of the literal "".
string message3 = System.String.Empty;
//Initialize with a regular string literal.
string oldPath = "c:\\Program Files\\Microsoft Visual Studio 8.0";
// Initialize with a verbatim string literal.
string newPath = @"c:\Program Files\Microsoft Visual Studio 9.0";
// Use System.String if you prefer.
System.String greeting = "Hello World!";
// In local variables (i.e. within a method body)
// you can use implicit typing.
var temp = "I'm still a strongly-typed System.String!";
// Use a const string to prevent 'message4' from
// being used to store another string value.
const string message4 = "You can't get rid of me!";
// Use the String constructor only when creating
// a string from a char*, char[], or sbyte*. See
// System.String documentation for details.
char[] letters = { 'A', 'B', 'C' };
string alphabet = new string(letters);
Handout 2
static void Concatenation(string s2)
{
string s1 = "Morning is ";
string s3 = string.Concat(s1, s2);
Console.WriteLine(s3);
Console.ReadLine();
}
static void Main(string[] args)
{
string message3 = "rainy.";
Concatenation(message3);
}
