Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 1

'Lev Vygotsky', a Soviet psychologist, has propounded the "Socio-cultural Theory". This theory implies the idea that social interaction plays a crucial role in the development of learners' cognitive ability. 
In Vygotsky's view, the above-mentioned kind of support is called 'scaffolding' as it refers to a process through which:

  • required assistance is given to children according to their individual needs.
  • temporary support is imparted to the children to enhance their learning skills.
  • individualized support is provided to children to increase their learning boundaries.

So, it could be concluded that in Vygotsky's view, the above-mentioned kind of support is called 'scaffolding'.

  • Abstract thinking is the ability to think about objects, principles, and ideas that are not physically present. It is a great way to generate new ideas and gain new insights during any problem-solving process.
  • Peer tutoring refers to the learning process where fellow students teach each other. In this strategy, a higher-performing student is paired with a lower-performing student to teach specific skills.
  • Generalization refers to the tendency to have conditioned responses caused by related stimuli.

Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 2

In a class individual learners differ from each other in terms of rate of development.
The rate of development of an individual child is different from that of another child. This principle is known as the ‘principle of individual differences’. For instance, some children may learn to walk in 8 months, while some may take more than a year to start walking. 
It is important for teachers to know variables such as physical characteristics, intelligence, perception, gender, ability, learning styles, which are individual differences of learners. An effective and productive learning-teaching process can be planned by considering these individual differences of students.

निर्देश: गद्यांश को पढ़िए और नीचे दिए गए प्रश्न का उत्तर दीजिए।
प्रेम आत्मा का भोजन है, प्रेम परमात्मा की ऊर्जा है जिससे प्रकृति का सारा सृजन होता है। आध्यात्म जगत में प्रेम से ज्यादा महत्त्वपूर्ण कोई शब्द नहीं है। यही वह रसायन है जो आत्मा को परमात्मा से जोड़ देता है। जब आप प्रेम में उतर जाते हो तो प्रेम का प्रत्युत्तर अपने आप आना शुरू हो जाता है। आप सद्गुरु की आँखों में प्रेम से झांकते हो तो सद्गुरु की प्रेम ऊर्जा आपको ऐसे लपेटने लगती है कि आप मंत्रमुग्ध होकर उसी के हो जाते हो। सद्गुरु को पकड़ो। पकड़ने का अर्थ है – सबसे पहले वहां साष्टांग हो जाओ, झुक जाओ यानि अहंकार के विसर्जन का, प्रेम का, प्रीती का अभ्यास सद्गुरु के चरणों से शुरू करो।  एक बात और है – प्रेम करना नहीं होता, प्रेम तो स्वयं हो जाता है। लेकिन इस प्रेम के होने में बुद्धि सबसे बड़ी बाधा बन जाती है। बुद्धि सोच विचार करती है। तर्क वितर्क करती है, वह खुले ह्रदय से अनुभव नहीं करने देती है।  बुद्धि बंधन है, उसी से मुक्त होना है और उपलब्ध रहना है उन प्रेम के क्षणों में। प्रेम की भूल-भुलैया का जरा अनुभव तो करो, लेकिन बुद्धि से नहीं, ह्रदय खोलकर प्रेम का दिया बनो। प्रेम का अर्थ होता है – दूसरों को इतना अपना बना लेना कि कुछ छिपाने को बचे ही नहीं। एक कसौटी दे रहा हूँ आपको, जब आपको लगने लगे कि उससे छिपाने को कुछ भी नहीं रहा तब समझना कि आपको सच्चे अर्थों में प्रेम हो गया है। सद्गुरु ही एकमात्र व्यक्तित्व है जो निःस्वार्थ प्रेम करता है।  उसे आपसे कुछ पाना नहीं है। उसे तो अपना सब कुछ आपके ऊपर लुटाना है। उसके प्रति प्रेम करने में कठिनाई का अनुभव नहीं होना चाहिए। वह तो खूँटी है। उसी खूँटी से अभ्यास करो। ऋषियों ने कहा है, प्रकृति से प्रेम करो।  फिर धीरे-धीरे मनुष्य पर आओ। मनुष्य से आकर आप सीधे परमात्मा तक पहुंचोगे। ऋषियों ने पहाड़ों को पूजा, नदियों को पूजा, वृक्षों को पूजा, चाँद-तारों को पूजा। किसलिए? उन्होंने सन्देश दिया कि सारी पृथ्वी से प्रेम करो। विराट अस्तित्व ही परमात्मा है। सबके प्रति प्रेम से इतना भर जाओ कि आपकी लय, आपका संगीत, आपका छंद उस परमात्मा से जुड़ जाये।  जो-जो शरीर में है वह सब ब्रह्मांड में है। सारे धर्म इसी बात का विज्ञान हैं और कुछ नहीं। प्रेम की एक ही साधना है, एक ही संकल्पना है जिसके साध लेने पर आध्यात्म की सारी साधनाएँ प्रकट हो जायेंगी।

भाषा अधिग्रहण: यह मानव मस्तिष्क की जन्मजात क्षमता के कारण मूल या दूसरी भाषा सीखने की अवचेतन प्रक्रिया को संदर्भित करता है।

  • यह एक प्राकृतिक प्रक्रिया है जिसके तहत बच्चे अपने मूल वातावरण की प्राकृतिक वातावरण में जो कुछ सुनते हैं उसे देखकर और दोहराकर भाषा सीखते हैं।
  • भाषा अधिग्रहण के लिए किसी औपचारिक निर्देश की आवश्यकता नहीं होती है, बच्चे बिना पढ़ाए ही भाषा सीख लेते हैं। यह एक स्वाभाविक प्रक्रिया है, इसलिए व्यक्ति अपनी मातृभाषा को नहीं भूलता है।

इस प्रकार, यह निष्कर्ष निकाला जा सकता है कि एक बच्चा प्राकृतिक वातावरण में अपनी पहली भाषा सीखता है।

एक शिक्षार्थी अपने संज्ञानात्मक स्तर से एक सोपान ऊपर के अपठित गद्यांश की समालोचनात्मक सराहना द्वारा अपनी पठन क्षमता प्रदर्शित करती है।
यह किसके अधिक निकट है? 
Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 8

बोधगम्य निवेश- समझ विकसित करने के लिए उपयोग में लायी जाने वाली विभिन्न प्रकार की सामग्री को बोधगम्य निवेश कहते है I
स्टीफन क्रैशन भाषा विज्ञान के क्षेत्र में एक विशेषज्ञ हैं, जो भाषा अधिग्रहण और विकास के सिद्धांतों में विशेषज्ञता रखते हैं। उन्होंने द्वितीय भाषा अधिग्रहण का सिद्धांत दिया जो व्यापक रूप से जाना जाता है और अच्छी तरह से स्वीकार किया जाता है।
i + 1  पहले से भाषाई क्षमता और अतिरिक्त भाषाई ज्ञान हासिल कर लेने को दर्शाता है, परिकल्पना का दावा है कि समृद्ध परिवेश की अन्तःक्रिया से समझ या भाषाई क्षमता में आयी वृद्धि बालको के समझ स्तर से थोड़ा उच्च हो सकती है। 
भाषा के अधिग्रहण के लिए 'बोधगम्य निवेश' महत्वपूर्ण और आवश्यक घटक है।
बोधगम्य निवेश परिकल्पना को प्राकृतिक क्रम परिकल्पना के संदर्भ में पुन: स्थापित किया जा सकता है उदाहरण के लिए, यदि हम एक रैखिक क्रम (1, 2, 3 ...) में भाषा के नियमों को प्राप्त करते हैं , तो i अंतिम नियम या बालक के स्तर के अनुरूप सीखा भाषा ज्ञान है, और 'बोधगम्य निवेश' बालक के स्तर से थोड़ा ऊपर भाषा के अवसर की उपलब्धता को दर्शाता है। हालांकि,
इस बात पर जोर दिया जाना चाहिए कि कोई भी निवेश पर्याप्त नहीं है; प्राप्त निवेश बोधगम्य होना चाहिए।  
जब पर्याप्त बोधगम्य निवेश (इनपुट) प्रदान किया जाता है, तो i + 1 उपलब्ध होता है ।
यदि भाषा मॉडल और शिक्षक बालको के एक स्तर ऊपर के बोधगम्य निवेश प्रदान करते हैं, तो वे उन संरचनाएँ को सीखने के लिए पर्याप्त रूप से तैयार होते है, जो उनके स्तर से थोड़ा ऊपर है।
अतः निष्कर्ष निकलता है कि एक शिक्षार्थी अपने संज्ञानात्मक स्तर से एक सोपान ऊपर के अपठित गद्यांश की समालोचनात्मक सराहना द्वारा अपनी पठन क्षमता प्रदर्शित करती है। यह बोधगम्य निवेश के अधिक निकट है।
अतः विकल्प (A) सही  है।

निर्देश: निम्नलिखित गद्यांश को ध्यानपूर्वक पढ़कर पूछे गए बहुविकल्पीय प्रश्न का उत्तर दीजिए।
चुनाव पूर्व सर्वेक्षण एवं एक्जिट पोल का लोकतन्त्र में क्या महत्त्व है? यह प्रश्न विचारणीय है। लोकतन्त्र रूपी वृक्ष जनता द्वारा रोपा और सींचा जाता है, इसके पल्लवन एवं पुष्पन में मीडिया की विशेष भूमिका होती है। भारत एक लोकतान्त्रिक राष्ट्र है।लोकतान्त्रिक राष्ट्र में नागरिकों को विशिष्ट अधिकार और स्वतन्त्रताएँ प्राप्त होती हैं। भारतीय संविधान ने भी अनुच्छेद 19 (i) के अन्तर्गत नागरिकों को अभिव्यक्ति की स्वतन्त्रता प्रदान की है, लेकिन जनता के व्यापक हित पर प्रतिकूल प्रभाव डालने वाली स्वतन्त्रता बाधित भी की जानी चाहिए।
भारत जैसे अल्पशिक्षित देश में इस प्रकार के सर्वेक्षण अनुचित हैं। देश की आम जनता पर मीडिया द्वारा किए जाने वाले चुनाव पूर्व सर्वेक्षण और चुनाव के तुरन्त पश्चात् किए जाने वाले एक्जिट पोल का भ्रामक प्रभाव पड़ता है। वह विजयी होती पार्टी की ओर झुक जाती है। आज भी सामान्य लोगों के बीच ये आम धारणा है कि हम अपना वोट खराब नहीं करेंगे, जीतने वाले प्रत्याशी को ही वोट देंगे।
वर्तमान में बाजारवाद अपने उत्कर्ष पर है और मीडिया इसके दुष्प्रभाव से अनछुआ नहीं है। यह कहना अतिशयोक्ति न होगी कि आज मीडिया भी अधिकाधिक संख्या में प्रसार और धन पाने को बुभुक्षित है। मीडिया सत्ताधारी और मजबूत राजनीतिक दलों के प्रभाव में भी रहता है। ये दल धन के बल पर लोक रुझान को अपने पक्ष में दिखाने में सफल हो जाते हैं और सम्पूर्ण चुनाव प्रक्रिया को ही धता बता देते हैं। इस प्रकार सत्ता एवं धन इन सर्वेक्षणों को प्रभावित करते हैं। इन्हें दूध का धुला नहीं कहा जा सकता। भारत जैसे लोकतान्त्रिक राष्ट्र में जहाँ जनता निर्वाचन प्रक्रिया के माध्यम से अपना मत अभिव्यक्त करती है, वहाँ इन सर्वेक्षणों के औचित्य-अनौचित्य पर विचार किया जाना चाहिए।
न्यायालय को यदि संविधान के अनुसार चलने की बाध्यता है, तो संसद को संविधान में संशोधन करने की शक्ति प्राप्त है। वह अपने अधिकारों का प्रयोग करके कोई सार्थक प्रयास कर सकती है।

Q. 'बुभुक्षित' शब्द के लिए कौन सा वाक्यांश उपयुक्त है?

Directions: Read the following passage carefully and answer the questions given below it. 
Nature is an infinite source of beauty. Sunrise and sunset, mountains and rivers, lakes and glaciers, forests and fields provide joy and bliss to the human mind and heart for hours together. Everything in nature is splendid and divine. Every day and every season of the year has a peculiar beauty to unfold. Only one should have eyes to behold it and a heart to feel it like the English poet William Wordsworth who after seeing daffodils said: And then my heart with pleasure fills and dances with the daffodils?
Nature is a great teacher. Early man was thrilled with the beauty and wonders of nature. The Aryans worshipped nature. One can learn lessons in the vast school of nature. Unfortunately, the strife, the stress and the tension of modern life have made people immune to the beauties of nature. Their life is so full of care that they have no time to stand and stare. They cannot enjoy the beauty of lowing rivers, swinging trees, flying birds and majestic mountains and hills. There is, however, a cry to go back to the village from the concrete and artificial jungle of cities. Hence the town planners of today pay special attention to providing enough natural scenic spots in town planning To develop a balanced personality, one needs to have a healthy attitude which can make us appreciate and enjoy the beauty of nature. There is another balm to soothe our tired souls and listless minds than the infinite nature all around us. We should enjoy it fully to lead a balanced and harmonious life, full of peace and tranquility.

As I Watch You Grow
Do you know how much you mean to me?
As you grow into what you will be.
You came from within, from just beneath my heart.
It's there you'll always be, though your own life will now start.
You're growing so fast it sends me a whirl,
With misty eyes I ask, Where's my little girl?
I know sometimes to you I seem harsh and so unfair,
But one day you will see, I taught you well because I care.
The next few years will so quickly fly,
With laughter and joy, mixed with a few tears to cry.
As you begin your growth to womanhood, this fact you must know,
You'll always be my source of pride, no matter where you go.
You must stand up tall and proud, within you feel no fear,
For all you dreams and goals sit before you very near.
With God's love in your heart and the world by its tail,
You'll always be my winner, and victory will prevail.
For you this poem was written, with help from above,
To tell you in a rhythm of your Mother's heartfelt love!

Read the passage carefully and answer the questions that follow. Some words may be highlighted. Pay attention.
While the apprehension of losing job security is the most natural human tendency, there are some factors like technology that are beyond an individual's control. The sooner the employees embrace the truth, the easier it would be to convert it into an opportunity. This can be done by upgrading employee-skillset with the following skills for the requirement of future roles:
Leadership: The ability to lead the automation change will be a crucial skill in the organization. The leader will be also responsible for identifying the right talent in the machine age and engaging the workforce through human touch points.
Information Technology: Who can handle technology better than the technologists themselves? However, automation will force employees to hone their understanding of big data, machine learning, cloud computing, augmented reality, and mathematical and analytical skills. With the huge amount of data available, they should be able to apply it to present insight.
Management: The future workplaces will be a collaboration of machines/robots and humans. Hence, the managerial skills required to strike a balance between machines and human emotions, and making them work alongside will also come handy.
Soft Skills: Machines are after all machines. They may do work more quickly and efficiently, but they can't bring in 100 percent human touch and feel. There will be areas where people to people interaction, human relationships, and networking will still matter, hence soft skills such as communication, social and behavioural, cognitive and emotional intelligence would be expected from the employees.
It's about time that employees start reskilling/upgrading their skills and search for relevant programmes/courses in their organizations or outside. For example, IT major Capgemini is planning to train each of its one lakh employees in India in digital skills by 2018. Intel has launched 60 courses as a part of its 'AI Developer Education Programme' to train 15,000 Indian engineers, developers, scientists, and students.
It can't be denied that automation will impact the jobs considerably in India. However, developing people-centric skills and upgrading/reskilling for new roles could help employees tide over the automation wave.

Q. An employee-skillset should be upgraded with which of the following for the requirement of future roles?
Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 15
  • According to the passage, ‘This can be done by upgrading employee-skillset with the following skills for the requirement of future roles: Leadership, Information technology, Management and Soft skills’.
  • The following has also been mentioned under the title of Soft skills: ‘There will be areas where people to people interaction, human relationships, and networking will still matter, hence soft skills such as communication, social and behavioural, cognitive and emotional intelligence would be expected from the employees.’
  • Therefore, we can infer that all the three options 1,2 and 3 are correct.

Thus, the correct asnwer is Option 4.

Nitu, a language learner, is finding certain topics taken up in class ‘difficult’. She is not able to understand the basic ideas and is also not able to handle the practice exercises or problems. Which one of the following is NOT the possible reason behind this challenge of teaching language?
Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 16

All of us have had the experience as students in the school of finding certain topics taken up in class ‘difficult’. 

  • In some cases, a sensitive and resourceful teacher provides special help in various ways to help learners overcome such difficulties fairly quickly so that they could keep up with the others.
  • In other less happy cases, the difficulty and lack of understanding were overcome only much later “ in remedial lessons, but sometimes never at all. This happens over and over again to many students at all levels.

Reasons behind challenges of teaching language:

  • This is because there is a mismatch between what the teaching plan for the topic assumes as available prior knowledge and what individual students actually have.
  • This is a problem that always comes up when a standard syllabus is covered according to a fixed calendar and learners are not ready for the given lesson.
  • If they do not learn as expected, it is because of this inadequate preparation, and not because of low learning capacity
  • The standard syllabus for any subject is based on certain logical and reasonable assumptions. The syllabus for Class V builds on the Class IV syllabus, and the Class VI syllabus builds on what is in the Class V syllabus, and so on.
  • The problem in the classroom arises because every child has not properly learned or mastered everything covered earlier. Teachers often do some revision before taking up a new topic. This is of course useful, but may not be enough.

So, it could be concluded that 'this is the problem of low learning capacity and learners' ignorance which could be improved by drill and practice exercise' is not one of the best possible reasons behind the above-mentioned challenge of teaching language.

The total simple interest for Rs 500 in 8 years and Rs 300 in 16 years is Rs 1100. If the rate of interest is equal in both cases. Then find the rate of interest.
Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 20

Given:
The total simple interest got in Rs 500 in 8 years and Rs 300 in 16 years is Rs 1100
The rate of interest is the same for both cases.
Formula used:
Simple Interest (SI) = (Principal (P) × Rate of interest (R) × Time (T)) / 100
Calculation:
Let, the rate of interest be R
As per the question,
1100 = (500 × R × 8) / 100 + (300 × R ×16) / 100
⇒ 1100 = (4000 × R) / 100 + (4800 × R) / 100
⇒ 1100 = (40 × R + 48 × R) 
⇒ 88R = 1100
⇒ R = 1100 / 88
⇒ R = 100 / 8
⇒ R = 12.5 %
∴ The rate of interest is 12.5 %

Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 23

Given:
The height of the tank = 10 m
The length of the tank = 20 m
The width of the tank = 15 m
Formula used:
The surface area of the cuboid = 2 × (ab + bc + ca)     Where, a = The length of the cuboid, b = The width of the cuboid and c = The height of the cuboid
Calculation:
Let us assume the total cost of the plastering be X
⇒ The total surface arae of the tank = 2 × (20 × 15 + 15 × 10 + 10 × 20) = 2 × (300 + 150 + 200) = 650 × 2 = 1300 m2
⇒ The surface for plastering = 1300 - (15 × 20) = 1000 m2
⇒ The cost of the plastering of the tank = 1000 × 0.80 = 800 rupees
∴ The required result will be 800.

What are the properties of the image formed by the plane mirror?
A. Virtual and inverted
B. Virtual and erect
Detailed Solution for REET Level 2 Mock Test - 9 (Science and Mathematics) - Question 28

Plane Mirror: A plane mirror is a mirror with a flat (planar) reflective surface.

The characteristics of an image formed in a plane mirror:

  • The image formed by the plane mirror is virtual and erect i.e. image cannot be projected or focused on a screen.
  • The distance of the image ‘behind’ the mirror is the same as the distance of the object in front of the mirror.
  • The size of the image formed is the same as the size of the object.
  • The image is laterally inverted, i.e. left hand appears to be right hand when seen from the plane mirror.
  • If the object moves towards (or away from) the mirror at a certain rate, the image also moves towards (or away from) the mirror at the same rate.

From above it is clear that images are formed by the Plane mirror is virtual, erect, and laterally inverted.
