Several days into the study, some of the students in the math-based reading program were getting frustrated by the frequent questions from their teacher. The students wanted to see the story in the books progress quickly, and they began acting out. The teacher decided it was best to either let these students join the control reading program or to try reading on their own in a different part of the classroom. Thus these students no longer participated in the math-based reading program. The researchers found that students in the math-based reading program performed much better on the PICO post-test than students in the control reading program. Which internal validity threat is most likely occurring in this scenario

Answers

Answer 1

Answer:

The internal validity threat that is most likely occurring in this scenario is:

Selection threat.

Explanation:

Selection threat or bias results from how groups were selected for the test, especially when the different groups were not comparable before the study.  For example, some of the students were frustrated by the frequent questions from their teacher.  They wanted quick progress, and as a result, started acting out.  Grouping these students together as a control group creates a threat called a selection bias or selection threat.  It shows that any other factor (reading on their own and no participation in the math-based reading program) than the reading program leads to the post-test differences between the groups.

The assertion that non-formal institutions have no role to play at the PROCESSING STAGE of
the Systems Theory is an empty rhetoric.

Answers

Answer and Explanation:

The processing phase of system theory refers to the ability of a single system to create itself, forming boundaries and defining a complete objective before interacting with other systems. These limits and goals are largely influenced by non-formal institutions, as these two elements are formed thanks to the creation of rules, beliefs and concepts that non-formal institutions establish in a community. Thus, we can conclude that the main point of processing a system is influenced by concepts and ideas created by non-formal institutions. In this case, it is incorrect to state that non-formal institutions do not have a role to play in the processing phase of systems theory.

why election campaign is required for democratic elections​

Answers

Answer:

it may prove dangerous if political parties and candidates are given freedom to conduct their electiob campaign the way they want to..

So it is essential to regulate campaign to ensur that every political party and candidates gets a fair amd equal chance to compete.

Answer:

Explanation:

Because voters are obligated to be informed. If they were not, then the best way to determine a government would be to set up a system using random numbers as its basis.

Take out the dice (8 of them). The person who roles the closest to 15 wins. Want to make it harder? The first person to roll an 8 wins. No cheating, now.

Does that sound ridiculous? It is. Better to have an informed electorate. If you are in the United States, would it surprise you to know that Canada has 5 elected parties, one of which is devoted to taking Quebec out of Canada. Try running a party like that in the US where (say) Texas California and New York wanted to suscede from the US.

Already happened (with different states)? Yes it did, but the difference is that Canada, if it breaks up (hardly likely) will do it peacefully.
