Communication
Communication is a two way street. This means that both the person communicating and the person being communicated to have to participate communication happens when information is shared between two people. Since communication is a two-way street, successful communication relies just as much on the person receiving the message as it does on the person sending the message.
When most people think of communication, they probably think of talking or verbal communication. However it is important to remember that talking is not the only form of communication. In addition to verbal communication, you communicate non-verbally with body movements and facial expression. Good communication skills not only help to improve your personal relationship, but also our success in education.
So, successful educational communication is dependent upon the following skills:-
1. Listening
2. Verbal communication
3. Non-verbal communication
4. emotional awareness
5. Written communication
6. Communication in different situation

  • Evaluate, extend, engage, explain and explore
  • Explain, engage, explore, evaluate and extend
  • Engage, explore, explain, evaluate and extend

Teaching Aptitude
Learning is an ‘active’ process which allows students to construct new idea or concept based upon their current and past knowledge. Students develop a cognitive structure, making meaning out of experience. This means the student can develop ideas beyond what he or she has been given.
Process/sequence of teaching, learning activities in a constructors approach

Ques 5: which among the following is the usually recommended sequence in an intervention-based action research process ?

  • Plan, act, observe and reflect
  • Observe, plan, act and reflect
  • Reflect, plan, act and observe
  • Observe, act, reflect and plan

Research Aptitude

Action research process may move in the cycles. It is like a heuristic method as the next action is bead on the previous result. This PAOR approach is reflected through the diagram of action research

Ques 6: Effective educational communication is :

  • non-reciprocal

Ques 7: A circle has the same area as that of a diagonal of a square of length 11.0 cm. what is the diameter of the circle ?

  • -8.7 cm
  • -17.4 cm
  • -7.8 cm
  • -15.6 cm

Mathematical Reasoning and Aptitude
Given that,
Area of circle Area of Square
Diagonal of square = 11 cm
Let side of square = 9 cm

Acc to Pythagoras Theorem
C2 = a2 + b2
(11)2 = (a)2 + (a)2
121 = 2a2
⇒=121/2⇒√(a&121/2)
Area of square = a2 = 121/2
Now, according to question
Area of Circle = Area of Square (where in a is the radius of circle)
πr^2= a2
πr^2=121/2
r2 = 121/ 2π
Substituting the value of π = 3.142
R =121/(2⨯3.14)=19.25
R = √19.25 = 4.38
Diameter of Circle = 2 π = 2⨯4.38
8.76~8.7 cm
= 8.76

Ques 8: The two cities P and Q are 360 km apart from each other. A car goes from P to Q with a speed of 40 km/hr and returns to P with a speed of 60 km/hr. What is the average speed of the car ?

  • 45 km/hr
  • 48 km/hr
  • 50 km/hr
  • 55 km/hr

Mathematical Reasoning and Aptitude
Avg. speed = total Distance / total time
Total Distance cover by car
= 360 + 360 = 720 km
Time taken to go from P to Q = 360/40 = 9Hrs
Time taken to go from Q to P = 360/60 = 6Hrs
Total time taken – 9 + 6 = 15 Hrs
Avg.Speed = 720/15 = 48km/hrs

Ques 9: Determine the term ‘X’ in the following series.
2,9,20,35,54,77,X

  • 104
  • 102
  • 89
  • 110

Logical Reasoning

2+7 = 9 11 is 4 more than 7 and
9 + 11 = 20 15 is 4 more than 11 and
20+15 = so on. In this pattern each
than the last increase and
35 + 19 = 54 the missing term would be 104.
54+23 = 77
77+27 = 104

Ques 10: The converse of ‘All cats are mammals is :

  • some mammals are not cats
  • no mammals are cats
  • some mammals are cats
  • all mammals are catsy

Logical Reasoning
The converse of a categorical or implicational statement is the result of reversing its two constituent statements. For the implication P→Q the converse is Q→P for the categorical proposition all S are P, the converse is all P are S. either way, the truth of the converse is generally independent from that of the original statement.

Ques 16: Which among the following terms are distributed in the statement, ‘No dogs are reptiles’?

  • Only subject term
  • Only predicate term
  • Both subject and predicate terms
  • Neither subject nor predicate term

Logical Reasoning
Distribution is the status of a term in regard to extension. The subject term is distributed in statement whose quantity and undistributed. the given statement is universal as it includes ‘No’ with the subject ‘Dog’ so, the subject is distributed.
In affirmative propositions the predicate term always taken particularly (and therefore distributed) and in negative propositions the predicate is always taken universally (and therefore distributed). The given statement is a negative proposition so predicate are reptiles is universal and distributed.

Ques 17: Given below are two statements-one is labelled Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Pedagogy and social interaction are two major result-oriented activities of a teacher.
Reason (R) : Communication has a limited role in both these activities.
In the light of the above statements, choose the correct option from the following.

  • Both (A) and (R) are true and (R) is the correct explanation of (A)
  • Both (A) and (R) are true but (R) is not the correct explanation of (A)
  • (A) is true but (R) is false
  • (A) is false but (R) is true

Teaching Aptitude
Pedagogy and social interaction are indeed two major result oriented activities of a teacher. Pedagogy is the method and practice of teaching, get result. If the teacher takes into account the various factors involved such as the availability of resources, learner’s characteristics, individual differences etc. and plan the instruction with the most suitable method aids and resources possible to ensure equality of opportunity to every learner, teaching is effective. Teaching is also effective when the teacher interacts and communicates well not only with the learner but also the other members of the teaching staff, school management/administration and parents. Hence A is true.
Communication is the vehicle that carries pedagogy and social interaction forward. So it plays not only a limited role but a big role in both their activities. Hence (R) is false.

Ques 19: At the stage of data analysis, which quantitative techniques have been used by a researcher, the evidence warrants the rejection of Null Hypothesis (Ho). Which of the following decisions of the researcher will be deemed appropriate ?

  • Rejecting the (H0) and also the substantive research hypothesis
  • Rejecting the (H0) and accepting the substantive research hypothesis
  • Rejecting the (H0) without taking any decision on the substantive research hypothesis
  • Accepting the (H0) and rejecting the substantive research hypothesis

Research Aptitude
Like any hypotheses a substantive hypothesis is an assumption about the relation between two or more variables. It is called substantive feel, the purpose of distinguishing it from the statistical hypothesis (Null, Alternative) because it is not operationalized. An operationalized hypothesis phrased clearly to show how the variables are manipulated or measured or how the main concepts were put into effect.
In the eventuality of rejection of the Null hypothesis after quantitative data analysis, the substantive research hypothesis should be accepted.

Ques 20: If data has been recorded using technical media, which among the following is a necessary step on the way to its interpretation ?

  • Transcription
  • Structural equation modeling
  • Sequential analysis
  • Sampling

communication
Interpreting and analyzing the collected data is essential to make inference and arrive at conclusions. How-ever, data should be in comprehensible form to be useful for the purpose. Qualitative data is generally descriptive and need to be coded for ease of analysis.
Qualitative data collected through technical media such as audio or video recording first needs to be transcribed (Put though, speech or data in to written or printed form) only then can it be coded.
Data transcription refers to the process by which certain qualitative data is interpreted as translated into words that can be categorized as coded and studied. Structural equation modeling is a multivariate statistical analyses relationship between measured variables and latent constructs.

Ques 28: if the income of Company A in the year 2018 was 90 lakhs, ten the net profit (in lakhs) of Company B in 2018 is what percent more than the net profit (in lakhs) of Company A?

  • 30%
  • 60%
  • 75%
  • 80%

income of company A in year 2018 = 90 Lakh% profit = 20%
Expenditure of company A in 2018 = 90⨯100/(100+20)
= 90⨯5/6 = 75 lakh
New profit of company A in 2018 = 90-75 = 15 lakh
Net profit of Company B in 2018 = 72-45 = 27 lakh
Difference in Net Profit = 27-15 = 12 lakh
Required % = 12/15⨯100 = 80%

Ques 29: If the expenditure of Company A in year 2017 was 45 lakhs, then the net profit (in lakhs) of Company A is what percent of net profit (in lakhs) of Company in the same year?

  • 15%
  • 25%
  • 40%
  • 75%

expenditure of company A in year 2017 = 45 lakh % profit = 10%
Profit = 10⨯45/100 = 4.5 lakh
Profit of company B in 2017 = 80-50 = 30 lakh
Required % = 1.5/30⨯100 = 15%

Ques 30: If the income of the Company A in the year 2014 happened to be 32.5 lakhs, then what was the sum of the net profit (in lakhs) of Company A and Company B in 2014?

  • 12.8 lakhs
  • 13.2 lakhs
  • 15 lakhs
  • 16.5 lakhs

income of company A in year 2014 = 32.5 lakh % profit = 25%
Expenditure of company A in 2014
=(32.5×100)/((100+25))=(32.5×100)/125=26 lakh
Profit of company A = 32.5-26=6.5 lakh
Sum of profit of company A and B in 2014 = 6.5 + 10 = 16.5 lakh
