📚 Types of research
1⃣ Secondary research
✔️ a type of research which is based on sources or data that are one step removed from the original information.
⬇️
they refer to the sources and data which have already been collected and analyzed by someone else.
2⃣ Primary research
✔️ It is a type of research in which researchers gather original data (primary data) to answer a particular research question. When researchers gather first-hand data, the outcome is knowledge nobody had before.

📚 Types of Hypotheses
1⃣ directional hypothesis
✔️it states the direction of the predicted relationship or difference between the groups
✔️ example : “Children who show high achievement motivation will have higher anxiety scores on the Children’s Manifest Anxiety Scale than will children with low achievement motivation”
2⃣ nondirectional hypothesis
✔️it states that there is a relationship or a difference between the groups but does not specify the direction of that difference.
✔️ example : “Achievement motivation and anxiety level are related”
3⃣ null hypothesis (symbolized as H0)
✔️ it states that there is no relationship between the variables or no statistically significant differences between the groups in the study.
✔️ example : “There is no relationship between children’s achievement motivation and their anxiety level in the population.”

📚 Kinds of Research
🔴 exploratory research
✔️exploratory research is to explore the mysteries of the universe.
✔️ probably most research projects were initially exploratory since no precedent had been available.
✔️ many discoveries and inventions have been partially the outcome of exploratory research.
✔️ conducting exploratory research is quite difficult because there is no helpful guideline for the reasercher to follow.
✔️ in some instances, the researchers follow a trial and error procedure to find out something about an unknown phenomenon.
🔴 confirmatory research
✔️ confirmatory research refers to exact or partial replication of previous research in order to consolidate already discovered facts and relations among facts .
✔️ in the field of language education, most research projects are either partial or complete replication of the previous research ➡️ the reason is the diversity of variables and factors involved in language and language-related areas.

☑️ pure research
✔️ pure research is, in simple terms , research for the sake of research .
✔️ this kind of research is conducted to find out the relationship among different factors.
✔️ a pure reasercher is not very much concerned with the applications or implications of his findings to the real world .
⬇️
he tries to uncover new relaions , to add to human body of knowledge , and to formulate generalizations and laws .
☑️ applied research
✔️ applied reaserch , on other hand , attempts to utilize the findings of the pure reaserch.
✔️ an applied researcher tries to apply the findings of pure reaserchers to the real world.
✔️ applied reaserchers are mainly responsible for the good or the evil of the findings.
⭕️ for example,the discovery of nuclear power was the outcome of pure research. Its application , however , whether to produce nuclear bombs for destructive purposes or nuclear rays for humanitarian purposes is the responsibility of applied researchers .

💢 Sign and sign systems 💢
points :
✔️ sign : an intersection or relationship of form and meaning .
⬇️
form = concrete
meaning = mental or cognitive
✔️ a sign is neither form nor meaning, but simultaneously both .
✔️ communication : use of signs
✔️ language : the customary sign system of humankind .
⭕️ types of signs
1⃣ icon : an icon is a sign whose form has actual characteristics of its meaning.
2⃣ index : an index is a sign whose form has characteristics which are only associated in nature with its meaning.
3⃣ symbol : a symbol is a sign whose form is arbitrarily or conventionally associated with its meaning.
❇️ evidence for the symbolic nature of linguistic signs :
1⃣ translation equivalents
2⃣ synonyms
3⃣ iconically expressible meanings

💢 Six aspects of the general nature of language 💢
1⃣ arbitrariness
the forms of morphemes are only arbitrarily related to their meanings .
2⃣ displacement
displacement is the characteristic that in languages meanings are expressed which are " displaced " or removed from the concrete or physical presence of the object or stimulus, outside the individual, of those meanings.
⬇️
like " past " and " future "
⭕️ even taking about hypothetical things like " golden mountains "
3⃣ creativity
creativity is the characteristic of languages that they readily and regularly permit the expression of new meanings.
⬇️
in fact , the finite forms of language are able to express a non-finite ( unbounded ) number of meanings.
⭕️ the creativity of language is owed particularly to the two properties of openness and recursion.
4⃣ duality
duality is the characteristic of linguistic signs that these have a two-part or dual structure , in which the meaningful whole is made up of meaningless parts .
⬇️
morphemes, that is , are meaningful , but phones and features which make up the phones are meaningless .
5⃣ grammaticality
grammaticality is the characteristic of languages that they have rather strict rules about how things may be said .
⬇️
only certain sounds may be combined in words , and meanings have to be combined in certain ways , in words and sentences.
⭕️ utterances in the language which follow the rules are said to be grammatical and those which don't follow the rules are ungrammatical.
6⃣ cultural transmission
languages differ from place to place in the world , and we have to learn the form appropriate for the place . This learning is called cultural transmission.
⭕️ if languages were completely instinctive or innate ( genetically encoded in us ) , like knowing how to swallow, digest , or to recognize faces , languages wouldn't differ this way , and we wouldn't need to learn them .

📚 Deductive presentation
📎 Advantages
✔️ it is a quicker and easier way to teach the rule to learners.
✔️ it confirms many students' expectations about classroom learning, particularly adult learners or analytical learners who want to know ‘what they are studying’.
✔️ time-saving ( explaining rules is usually quicker than guessing from examples). The class time can be used for more practice.
📎 Disadvantages
✔️ grammar explanation tends to be teacher-fronted and does not actively involve learners.
✔️ grammat explanation might be cognitively demanding for young learners.
✔️ starting with grammar explanation might demotivate learners.
✔️ it leads to the belief that language involves just knowing the rules.

📚 Inductive presentation
📎 Advantages
✔️ discovering rules by learners is likely to lead to more ‘meaningful, memorable, and serviceable’ knowledge.
✔️ it involves greater depth of processing which assists memory.
✔️it encourages the students' active involvement in grammar learning.
✔️ it is more challenging than simply receiving explanations.
✔️ it can be done collaboratively in the classroom.
✔️ figuring out the rule by themselves might encourage learner autonomy.
📎 Disadvantages
✔️ time-consuming _ it takes up time better spent on practice.
✔️ inferring rules might might result in the learners misunderstanding the rule.
✔️ it places high demands on teachers for class preparation.

💢 Constructs
📌 Constructs are abstractions that cannot be observed directly but are useful in interpreting empirical data and building theories.
Examples :
⭕️ motivation
⭕️ anxiety
⭕️ reading readiness
⭕️ underachievement
⭕️ creativity
⭕️ self-efficacy
Constructs may be defined in two ways:
1⃣ a constitutive definition, which gives their general meaning, like a dictionary type of definition.
2⃣ an operational definition gives meaning to a construct by specifying the operations that researchers would perform to measure or manipulate the construct.

Researchers, especially quantitative researchers, study variables and the relationships that exist among them.
⬇️
variable is a construct or a characteristic that can take on different values or scores across people or things.
Examples:
⭕️ Height
⭕️ weight
⭕️ intelligence
⭕️ vocabulary
⭕️ scores
⭕️ gender
💠 Types of Variables
There are several ways to classify variables.
💢 Variables can be categorical, or they can be continuous .
✔️ When researchers classify subjects by sorting them into mutually exclusive groups, the attribute on which they base the classification is called a categorical variable .
Examples:
📍Home language
📍father’s occupation
📍marital status
📍state of birth
✔️ The simplest type of categorical variable has only two mutually exclusive classes and is called a dichotomous variable.
Examples:
📎 pass–fail
📎 citizen–immigrant
📎 in-state or out-of state resident
✔️ When a variable has an infinite number of values within a range, it is a continuous variable.
Examples:
🌀Height
🌀weight
🌀age
🌀achievement test score
💢 Another important classification is whether the variable in a study is the independent variable or a dependent variable.
✔️ The independent variable is the antecedent variable that an investigator manipulates in order to determine its effect on another variable called the dependent variable.
✔️ The dependent variable is the variable we observe and measure.
🔳 Constants
✔️ The opposite of variable is constant ➡️ a constant is a fixed value within a study.
