Frobel's most important contribution to education was his development of the kindergarten. Frobel's method inspired and informed the work of Maria Montessori, Rudolf Steiner and others, who adopted his ideas and adapted his materials according to their own work.

'युग की प्राचीर' से मतलब समय की बाधाएँ है।

प्राचीन भारत में शिक्षा जीवन की वास्तविकताओं से परिपूर्ण होती थी। दिए गए गद्यांश के अनुसार, आधुनिक युग की भाँति प्राचीन भारत में भी मनुष्य के चरित्र का उत्थान शिक्षा से ही सम्भव था। सामाजिक उत्तरदायित्वों को निष्ठापूर्वक वहन करना प्रत्येक मानव का परम उद्देश्य माना जाता है। इसके लिए भी शिक्षित होना अनिवार्य है। जीवन की वास्तविकता को समझने में शिक्षा का उल्लेखनीय योगदान रहता है। भारतीय मनीषियों ने इस ओर अपना ध्यान केन्द्रित करके शिक्षा को समाज की आधारशिला के रूप में स्वीकार किया।

सुनना और पढ़ना ग्रहणशील श्रेणी में आता है जबकि बोलना और लिखना भाषा कौशल की उत्पादक श्रेणी के अंतर्गत आता है।

• बोलना और लिखना भाषा कौशल की उत्पादक श्रेणी के अंतर्गत आता है क्योंकि ये मौखिक और लिखित रूप में आउटपुट उत्पन्न करते हैं। यही कारण है कि इन्हें उत्पादक कौशल के रूप में जाना जाता है।
• सुनना और पढ़ना ग्रहणशील श्रेणी के अंतर्गत आता है क्योंकि शिक्षार्थी शिक्षक द्वारा दिए गए इनपुट को प्राप्त करता है। यही कारण है कि इन्हें ग्रहणशील कौशल के रूप में जाना जाता है।

इसलिए, हम यह निष्कर्ष निकाल सकते हैं कि बोलना और लिखना भाषा कौशल की उत्पादक श्रेणी के अंतर्गत आता है।

सीख लीगे भाषा तथा अपेक्षित भाषा मे संवाद करने के लिए प्रयुक्त की जाने वाली भाषा शिक्षण की विधि अनुवाद विधि हैI अनुवाद विधि के गुण :-

• इसे बड़ी सरलता से पढ़ाया ज सकता हैI
• इस विधि मे बोलने की अपेक्षा लिखने और पढने पर तथा भाषा की अपेक्षा भाषा के तत्वों के ज्ञान पर अधिक बल दिया जाता हैI
• द्वितीय भाषा के ढांचों का ज्ञान कराया जाता है तथा भाषा कौशलो मे दक्षता ली जाती हैI
• द्वितीय भाषा के शब्दों एवं वाक्यों का ज्ञान आना चाहिए ना कि नियम व मातृभाषा के अवतरणों का द्वतीय भाषा मे अनुवाद किया जाता हैI

'बोली' किसी भाषा का कोई प्रभेदक शैलीरूप न होकर स्वयं भाषा होती है जो अपने सामाजिक प्रकार्य में किसी अन्य भाषा पर आश्रित होती है। दूसरे शब्दों में यह कहा जा सकता है कि शुद्ध भाषावैज्ञानिक दृष्टि से इस संदर्भ में बोली और भाषा में भेद करता संभव नहीं। उदाहरण के लिए खड़ी बोली के रूप में मान्य जिसे हम हिंदी भाषा कहते हैं, उसमें ब्रज, अवधी, भोजपुरी, मैथिली आदि उसकी बोलियों में शब्द, रूपरचना या व्याकरण के आधार पर भाषा-बोली का भेद करना संभव नहीं। शुद्ध भाषिक रचना की दृष्टि से जिस प्रकार खड़ीबोली एक “भाषा” है उसी प्रकार ये बोलियाँ भी 'भाषा' हैं क्योंकि इनमें भी उसी प्रकार भाषिक प्रतीकों की संरचनात्मक व्यवस्था मिलती है, जिस प्रकार खड़ी बोली में।
अतः हम कह सकते हैं कि भाषा वैज्ञानिक दृष्टि से भाषा और बोली में- अंतर नहीं होता।

Activity in option 4 will pose a question that will provide a meaningful extrapolative about the steps that should be taken to save wildlife.

Reading sub-skill refers to the well-planned reading approach which helps the learners to comprehend and perceive the meaning of the text effectively. There are different kinds of reading sub-skill and 'Skimming' is one of them.

Intensive reading includes the reading that is being done in-depth to grasp the meaning and comprehend the written text. It is also known as in-depth reading. Intensive reading includes short texts (short stories, articles, blogs, etc.), then the reader organized them in an order to make a conclusion to decode the meaning of it. The reader here reads to achieve certain aims and objectives. A language teacher asked the students to read a short story and to tell the summary of it by concluding the main idea of the story while decoding the meaning of the story.
Therefore, it could be concluded that the reading activity encouraged by the teacher is intensive reading.

Language is a tool to communicate with the world. Considering the size of the world, there have been many civilizations in different parts of the world which have developed different languages.

In the evaluation of Hindi language, the basis of evaluation is not proper to divide it into pass-failed categories only. Language is a broad subject. In whose assessment various evaluation tests should be used so that the evaluation can be comprehensive.

The synonym of the phrase 'very small' is 'tiny'.

The correct answer is 'To meet our food security and climate needs proper balance between mineral and particulate-based organic matter is required, considering human interaction.'
Let's refer to the following lines of the passage:
Sequestering soil carbon effectively requires an understanding of how particulate organic matter and mineral-associated organic matter work, how human actions affect them, and how to build up both types to meet our planet’s climate and food security needs.

There are many ways to teach language to children. Some of the ways are as follows:

• Teaching through various activities, summarizing the lesson after explaining it, getting children to formulate answers to various types of questions, problem-solving techniques, making them undertake surveys, and the like.
• Each technique belongs to a specific language teaching method that has a specific set of principles. Some teachers teach in ways that do not belong to any specific language teaching method.
• In natural settings, children automatically acquire the rules of his/her language because there is considerable exposure, and because (s)he receives all the care and affection that makes language learning possible. Yet, without an innate faculty for language, it would be impossible to acquire structures as complex as those of language. We need to activate this language faculty optimally in school.
• The teacher should pay attention to selecting and communicating study material. Analysis of study material should be minimum and children should be motivated to find and search for things independently.
• The teacher must synchronize the mental level of children, their curiosity, their participation, her own intervention levels, challenging activities, and conceptual clarity.

From the above, we can it is clear that we can teach language to children in a classroom through activities and by telling the summary of the lesson after explaining it.

According to the passage, the author mentions extensively about her temple visits and how she visited quite a few temples. She also describes the temples she visited. So, ‘temple fatigue’ refers to the mental and physical exhaustion that as arose from too many temple visits. 

Make Ria understand the meaning and the sound pattern and get the class as a whole to listen to these words through an audio – visual medium listening skills. students who develop better listening skills are more likely to feel confident, comfortable, and prepared to succeed in school. It can also help students build relationships because as they engage themselves in conversation, their peers are more likely to view them as open and interested.

India’s linguistic diversity is both a challenge and an opportunity in schooling. It is a challenge as the language-in-education policy could not, accommodate (all) the languages of the children in the curriculum and is merit and opportunity in terms of availability of languages in a typical Indian classroom where employing multilingualism as a strategy for teaching-learning of languages as well as the ‘content’ subject is possible and necessary. The language-in-education policy attempts to accommodate at least three languages within ten years of schooling. However, many tribal and minor languages are yet to find a place in the school curriculum.
If a teacher tells the students to visit at least three schools in your neighborhood and find the difference in the English language proficiency of learners and teachers, languages known/spoken by learners, and languages used inside and outside the classroom in the school then she is focusing on multilingualism and language education.

• Multilingualism is a natural phenomenon that relates positively to cognitive flexibility and scholastic achievement.
• Several recent studies have effectively demonstrated the positive relationship of bilingualism with cognitive growth and scholastic achievement. There is a highly positive relationship between bilingualism, cognitive flexibility, and scholastic achievement.
• Bilingual children not only have control over several different languages but are also academically more creative and socially more tolerant.
• The wide range of linguistic skills that they control equips them to negotiate different social situations more efficiently. 

Thus it is clear that Neha is focusing on multilingualism and language education.

• For a plano-convex lens, one of the surfaces is flat (Plano) and the other is curved (convex).
• The radius of curvature of the curved surface is given as 20 cm, and the refractive index of the material of the lens is 1.5.
• The focal length of the lens can be calculated using the lens maker's formula:

1/f = (n - 1) × (1/R1 - 1/R2)
where
f is the focal length of the lens,
n is the refractive index of the lens material,
R₁ is the radius of curvature of the first surface (the flat surface in this case, which is infinite), and
R₂ is the radius of curvature of the second surface (the curved surface in this case).
Since the first surface is flat, the radius of curvature R1 is infinite, and the term (1/R1) becomes zero. Therefore, the lens maker's formula simplifies to:
1/f = (n - 1) ×  (1/R2)------(1)
Calculation:
Substituting the values in equation (1), we get:
1/f = (1.5 - 1) × (1/20)
1/f = 0.025
f = 1/0.025
f = 40 cm
Therefore, the focal length of the plano-convex lens is 40 cm.
The correct answer is option (4)

Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain.

∴ The mode of the given set of data is 8

• The leaves have a green pigment called chlorophyll.
• It helps leaves to capture the energy of the sunlight.
• This energy is used to synthesize (prepare) food from carbon dioxide and water. 
• Since the synthesis of food occurs in the presence of sunlight, it is called photosynthesis.
• Photo means light and Synthesis means to combine.
• We find that chlorophyll, sunlight, carbon dioxide, and water are necessary to carry out the process of photosynthesis.
• It is a unique process on the earth.
• The solar energy is captured by the leaves and stored in the plant in the form of food.
• Thus, the sun is the ultimate source of energy for all living organisms. 
• By the middle of the nineteenth century, the key features of plant photosynthesis were known, namely, that plants could use light energy to make carbohydrates from CO₂ and water.

The taste buds for "sweet" are on the tip of the tongue; the "salt" taste buds are on either side of the front of the tongue; "sour" taste buds are behind this; and "bitter" taste buds are in the back.

Given:

Concept used:

Calculation:

∴ The required answer is √85.

The first step is to outline learning objectives, i.e. to determine what you want students to learn and be able to do that at the end of class.

• Convection refers to a process by which heat is transferred by the movement of a heated fluid such as air or water.
• Natural convection results from the tendency of most fluids to expand when heated i.e., to become less dense and to rise as a result of the increased buoyancy.

Examples of Convection:
Rainfall and thunderstorms:

• Clouds are formed when water in the ocean gets warmed and rises up. These warm water droplets, in turn, saturate which leads to the formation of clouds.
• The small clouds which are formed by this process collide with each other to develop bigger clouds. These large clouds which are commonly referred to as cumulonimbus result in rainfall and thunderstorm. Hence, 3 is correct. 

Melting of glaciers:

• The melting of ice is yet another example of convection. The temperature of the surface or boundary of ice increases as warm air blows over the surface; or water, which is at a higher temperature as compared to the ice, flows underneath it.
• As the temperature of the surface or boundary of ice alters, the ice melts. Hence, 4 is correct. 

Land and sea breeze:

• During the day, the land gets heated faster than the water. The air over the land becomes hotter and rises up.
  • The cooler air from the sea rushes in towards the land to take its place. The warm air from the land moves towards the sea to complete the cycle. The air from the sea is called the sea breeze. 
• At night it is exactly the reverse. The water cools down more slowly than the land. So, the cool air from the land moves towards the sea. This is called the land breeze. Hence, 1 is correct.

From the sun the heat comes to us through another process known as radiation.

• It cannot reach us by conduction or convection as there is no medium such as air in most parts of the space between the earth and the sun.
• The transfer of heat by radiation does not require any medium. It can take place whether a medium is present or not. Hence, 2 is not correct.

Enactive includes aids which provide direct experiences, such as field trips, dramatised experiences, etc.
Iconic includes aids which provide pictorial experiences.
Symbolic includes highly abstract experiences.

A control group is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternate explanations of the experimental results.
