An educational psychologist designs a demanding but fair spelling test that can be administered to grade school children. The te

st is found to be valid and reliable. A researcher selects the test to help evaluate a “cognitive” approach to teaching spelling. A 5th grade class is tested prior to being taught the new method at the beginning of the school year and then again after the new method is taught at the end of the year. The children show improvement on their spelling scores from the first to the second test administration, suggesting that the program was effective in helping children to learn to spell. What is a threat to the internal validity of the study?

The answer is: Testing

One thing that can question the internal validity of the case above is the difficulty between the first and the second test since the psychologists never really mention it.

If, let's say that the questions on the second tests are exactly the same as the first tests or have lower difficulties compared to the first one, the better performance given by the student is not necessarily influenced by the teaching method.

Andrew recently started hanging out with a group of peers who are all motivated to do well in school and are involved in academi
Elodia [21]

Answer:

A. Selective.

Explanation:

This could be looked at in the sense of a little disorder from little Andrew, though the act is selective, it could also come up as mutuism. Some adults with selective mutism are fully capable of speech and understanding language but are physically unable to speak in certain situations, though speech is expected of them.

The behaviour may be perceived as shyness or rudeness by others. A child with selective mutism may be completely silent at school for years but speak quite freely or even excessively at home. There is a hierarchical variation among people with this disorder: some people participate fully in activities and appear social but do not speak, others will speak only to peers but not to adults, others will speak to adults when asked questions requiring short answers but never to peers, and still others speak to no one and participate in few, if any, activities presented to them.

जम्मू आणि काश्मीर येथे सक्रिय असलेल्या काही दहशतवादी गटांची नावे व त्यांच्या नेत्यांची नावे लिहा.​
Katyanochek1 [597]

Answer:

काश्‍मीर हिमालयाच्या खोऱ्यातील एक प्रदेश. अफगाणिस्तान, मध्य एशिया, तिबेट व भारतीय उपखंड यांच्या मध्यभागी. भारताच्या जम्मू आणि काश्मीर या राज्याचा प्रमुख भाग.

काश्मीर खोऱ्याचा जवळजवळ २/३ भाग भारताच्या ताब्यात 'जम्मू व काश्मीर' या राज्याचा भाग . तर १/३ भाग पाकिस्तानच्या ताब्यात आहे.पाकिस्तानच्या ताब्यातील भागाला पाकिस्तानात 'आजाद कश्मीर' तर भारतात 'पाकव्याप्त काश्मीर' म्हणतात. जम्मू-काश्मीर आणि ईशान्य भारतामध्ये पसरलेला दहशतवाद आणि १४ राज्यातल्या १६५ जिल्ह्यांमध्ये सुरू असलेल्या डाव्या विचारसरणीच्या मूलतत्ववाद्यांमुळे संपूर्ण देशाची सुरक्षितता धोक्यात आली आहे. त्यातच नक्षलवाद्यांना मिळणाऱ्या माफियांच्या मदतीमुळे देशाचे दोन तुकडे झाले आहेत, असे म्हटले तर वावगे ठरणार नाही.

देशातल्या ६०८ जिल्ह्यांपैकी २३१ जिल्ह्यांना आज घुसखोर, दहशतवादी, नक्षलवादी यांच्यामुळे खूप मोठा धोका निर्माण झाला आहे. जम्मू-काश्मीर आणि ईशान्य भारतामध्ये पसरलेला दहशतवाद आणि १४ राज्यातल्या १६५ जिल्ह्यांमध्ये सुरू असलेल्या डाव्या विचारसरणीच्या मूलतत्ववाद्यांमुळे संपूर्ण देशाची सुरक्षितता धोक्यात आली आहे. देशाच्या सुरक्षेवर आलेले संकट पाहता केंद्र आणि संबंधित राज्य सरकार या प्रश्नाच्या मूळापर्यंत पोहोचले आहेत, असे म्हणता येईल का? देशाच्या सुरक्षेच्या दृष्टिकोनातून काही योजनांची आखणी करण्यात आली आहे का? देशाच्या एकसंधतेला चार प्रमुख गोष्टींमुळे धोका आहे. नक्षलवाद्यांनी देशाच्या ४० टक्के भागामध्ये धुमाकूळ घातला आहे. जम्मू-काश्मीरमध्ये १९८८ पासून छुपे युद्ध सुरू आहे. हे राज्य देशाच्या स्वातंत्र्यापासून अक्षरश: लष्कराच्या ताब्यातच आहे.
