a type of statistical hypothesis test that is appropriately chosen where –
based on previous studies – no direction of an effect, such as a difference
or correlation, is specified in advance (e.g., There will be a significant
difference in vocabulary recognition scores between the experimental and
control groups).two-way immersion education n
a type of mainly US bilingual education in which students learn through
two languages in programmes that aim to develop dual language
proficiency along with academic achievement. Both minority and English-
speaking students acquire a second language. Instruction is provided both
through the L1 of the minority students and through English. Such pro-
grammes integrate language minority and language majority students and
provide content area instruction as well as language development in two
languages.Students from the 2 language backgrounds are in each class and
they are integrated for most or all of their content instruction.
two-way task n
a type of information gaptask in which each participant has some
information not shared by the other and that information needs to be
shared to complete the task.
type n
in linguistics, a distinction is sometimes made between classes of linguistic
items (e.g. phonemes, words, utterances) and actual occurrences in speech
or writing of examples of such classes. The class of linguistic units is called
a typeand examples or individual members of the class are called tokens.
For example, hello, hi, good morning are three different tokens of the type
“Greeting”.
In mathematical linguistics the total number of words in a text may be
referred to as the number of text tokens, and the number of different words
as the number of text types. The ratio of different words in a text to total
words in the text is known as the lexical density or Type-Token Ratio
for that text.
