Karnataka TET Paper 2 Mock Test - 1 (Science and Mathematics) - Karnataka TET MCQ

Continuous and Comprehensive Evaluation (CCE) refers to a system of school-based evaluation of students that covers all aspects of students' development.

• CCE was introduced by the Central Board of Secondary Education (CBSE) in India to evaluate the student’s development in all aspects throughout the academic year on a continuous basis.
• The objective of CCE is to make evaluation an integral part of learning through diagnostic and remedial teaching.
• CCE helps improve student’s performance by identifying his/her learning difficulties at regular intervals right from the beginning of the academic session and employing suitable remedial measures for enhancing their learning performance.

CCE describes two different types of evaluations which include summative and formative assessment/evaluation.

• "Summative Evaluation", commonly known as  "Assessment of Learning" is a type of evaluation which:
  • measures, certifies, and reports the level of students' learning by assessing them at the end of the term.
  • produces an accurate description of students' potential and achievement to promote them to the next grades.
• "Formative evaluation", commonly known as "Assessment for Learning" is a type of evaluation which: 
  • monitor the child's progress throughout the teaching-learning process and improve students' academic achievements.
  • diagnoses and removes the learning difficulties of students with appropriate strategies.

So, it becomes clear that Continuous and Comprehensive Evaluation includes both formative and summative assessments using a wide variety of strategies.

The adverse effect of insisting on the same answers from all children will hinder the growth of the child's own understanding and imagination. Cognitive powers of a child, like imagination power, intelligence, ability to make a decision, etc. are related to the child's 'mental development' as mental development refers to the development of the ability to understand, learn, reason, think, perceive, and solve a problem.
Hence, the correct option is (C).

The Cephalocaudal Principle states that development proceeds from top to bottom. According to this principle, a child will gain physical control of their head first. After this, physical control will move downward to the arms and lastly to the legs.

Mental age ÷ Physical age × 100 = IQ
5/4 x 100 = 125
No matter what the child's chronological age is, if the mental age is the same as the chronological age, then the IQ will equal 100. Modern intelligence tests, including the current Stanford-Binet test, no longer compute scores using the IQ formula.

Children with special needs have unique learning requirements and it is the responsibility of the teacher to respond to these needs in a positive manner.

बहुभाषिकता: भिन्न-भिन्न प्रांतों के बच्चों द्वारा अलग-अलग प्रकार की भाषा बोले जाने को भाषायी विविधता या बहु-भाषिकता कहा जाता है। बहु-भाषिकता भारत की संस्कृति का अभिन्न अंग है।

भाषा मुख से उच्चारित होने वाली वह ध्वनि है जिसका प्रयोग मनुष्य अपने मन के विचारों का आदान-प्रदान करने के लिए करता है। यह बच्चों में दक्षता के साथ सहज अभिव्यक्ति के विकास को सुनिश्चित करता है।
भाषा एक औजार है जिसका उपयोग निम्न रूप से किया जाता है:

• जिंदगी के अनुभवों को साझा करने के लिए
• भाषा जिंदगी से जुड़ने के लिए सहायक है  
• भाषा जिंदगी को समझने के लिए उपयोगी है 
• भाषा जीवन जगत को प्रस्तुत करने के लिए सहायक है 
• जीवन संबंधी मनन और विचार शक्ति के विकास के लिए

अतः हम कह सकते है कि भाषा कठोरता से व्‍याकरणिक नियमों का अनुसरण करती है, कथन भाषा की प्रकृति के सम्‍बन्‍ध में उचित नहीं है।

अभिव्यक्ति से तात्पर्य मन के विचारों को स्वतंत्र रूप से खुल कर अभिव्यक्ति करने से है। मौखिक अभिव्यक्ति से तात्पर्य मन के विचारों को स्वतंत्र रूप से बोल कर अभिव्यक्त करने से है तथा लिखित अभिव्यक्ति के अन्तर्गत विषयानुकूल लेखन एवं अपने विचारों भावों को लिखित रूप में समझापाने का कौशल आता है।

Accumulate: To increase over a period of time. Example - Investigators have yet to accumulate enough evidence.
Dissipate: to slowly become less until it disappears or to (cause to) gradually disappear or waste. Example - The morning sun dissipated the fog. 
Let's see the meaning of the options given.

Azure is a variation of sky blue colour.

Option 2 is correct as this is a polite and correct way to request someone to not to do something. Option 1 is rude and offensive and options 3 and 4 are grammatically incorrect expressions.

Here, erratic means unpredictable.
Right means proper and expected. So, it is the opposite word to 'erratic'.

A fresh solution of sodium hydroxide is prepared in a test tube by dissolving 3-4 pellets of it in 5 ml of water. A piece of aluminium foil is dropped into it. A burning match stick is brought near the mouth of the test tube. Then, a pop sound comes. As before, the 'pop' sound indicates the presence of hydrogen gas. Metals react with sodium hydroxide to produce hydrogen gas. So, burning match stick extinguishes.

Average speed:

• The average speed is the total distance traveled by the object in a particular time interval.
• The average speed is a scalar quantity.
• It is represented by the magnitude and does not have direction.​
• Formula, average speed, s_avg = total distance/total time

Average velocity:​

• It is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
• Formula, average velocity, v_avg  = Δx/Δt
• The average velocity can be positive or negative depending upon the sign of the displacement.
• Average velocity is a vector quantity.
• The SI unit of average velocity is meters per second (m/s).

Instantaneous speed and instantaneous velocity:

• Instantaneous velocity is defined as the rate of change of position for a time interval that is very small (almost zero). 
• Instantaneous speed is the magnitude of the instantaneous velocity.
• It has the same value as that of instantaneous velocity but does not have any direction.

Formula used:
SI = (PRT/100) 
Amount = SI + P
Concept used:
A sum of money tripled means, Amount is three times of the principal
Calculation:
Let the sum of money be P
Amount in 10 years = 3P
Amount = (PRT/100) + P
3P = (PR/10) + P 
⇒ 2P = (PR/10) 
⇒ R = 20%
According to question, Amount = 5P
Let the time required for the sum to become five times be T
5P = (P × T/100) + P 
⇒ 4P = (P × 20 × T/100)
⇒ 4 = (T/5)
⇒ T = 20 years
∴ Time taken to five times the sum is 20 years.

• Elements are mainly classified into three categories based on certain properties. They are metals, non-metals and metalloids.
• Metals show distinct characteristics of lustre, malleability, ductility, and electrical and thermal conductivities.
• Cooking utensils should have good conducting capabilities. 

The given expression becomes 300000 + 4000 + 700 + 5 = 304705
Hence, answer option 3 is correct.

Given:
20% of P + 40% of Q = 80% of Q
Formula Used:
Percentages can be expressed as fractions or decimals. For example, 20% can be written as 0.2 or 1/5.
Solution:
20% of P + 40% of Q = 80% of Q
0.2P + 0.4Q = 0.8Q
0.2P = 0.8Q - 0.4Q
0.2P = 0.4Q
Now we can solve for P/Q:
P/Q = 0.4 / 0.2
P/Q = 2
This tells us that P is equal to 2Q.
P is 200% of Q.

It is imperative to say that the classroom environment created by the prospective teachers allows the learners to raise such questions coming to their mind. Teaching-learning situations are driven by learners' questions, rather than teachers' instructions. The effectiveness of the learning strands in empowering the prospective teachers for science practices has been investigated from the responses of the learners. A huge percentage of the learner responses indicates sharing of 'what they learn' with others. Also, a science teacher should summarise and assess the learners' ideas at the end of the discussion.

Magnesium hydroxide -

• It is an inorganic compound having the chemical formula Mg(OH)2.
• It is called 'Milk of Magnesia' because it looks like milk when dissolved in water.
• It is used to remove the acidity of the stomach.

Assessment is the process of gathering information with regard to abilities, interests, aptitudes, personality, attitude, and beliefs. It is an integral part of day-to-day life and is one of the essential works of the counselor.

Mathematics is the study of numbers, shapes, quantities, and patterns. It relies on logic and connects learning with children's day to day life. The assessment of mathematical learning refers to know the learning needs and filling the gap by remedial teaching.

Open-ended questions are those which require more thought and more than a simple one-word answer. Thus, option (2) best describes the example of an open-ended question.

The example of motion of a boy sitting in a moving car in relation to the car is incorrect because the motion of a boy sitting in a moving car in relation to the car is zero.

The process of Rusting of Iron is faster in Coastal areas.

• Iron rusts only when iron comes in contact with moist air.
• In coastal areas, the percentage of moisture in the air is high due to sea or ocean, while in the desert the air is dry and hot.
• Corrosion is faster due to higher percentage of moisture in the air in the coastal region as compared to the desert.
