Summary Of Journal Article By Karpicke And Blunt

In a journal article by Karpicke and Blunt (2012), two experiments were performed upon undergraduate students in order to test the effectiveness of retrieval learning versus elaborative study with concept mapping, on the student’s long-term ability to retain science material. In the opinion of many educators and students alike, most likely as a result of folk psychology, the assumption is that elaborative learning techniques are far more effective for long-term retention of material in comparison to the retrieval or self-testing learning technique (Karpicke & Blunt 2012, pp. 772). The aim of Karpicke and Blunt’s (2012) journal article is to test this assumption. In experiment one, four test conditions were set in which eighty undergraduate …show more content…

772-773). The results of this test proved that both the elaborative studying with concept mapping and retrieval techniques were highly effective on the students ability to recall material. However, the students who partook in the retrieval condition of study “Represented about 50% improvement in long-term retention scores,” (Karpicke & Blunt 2012, pp.773) Indicating it to be the condition of study with the greatest benefit to the students in long-term retention. In the second experiment , Karpicke and Blunt (2012) aimed to replicate these findings while also improving upon their ability to be generalised. They did this by including material to be studied with differing structures of knowledge as well as observing the relative effectiveness of the retrieval learning technique compared with the use of elaborative study done by a student as an individual. Using this method with a sample of 120 students, each student would study one piece of material using retrieval practice and then another piece of material using the method of concept …show more content…

Another change to the experiment that they implicated, was dividing the student participants, at the end of the week of study, into two halves to perform two different kinds of tests in order to assert their long term retention of their set material. One half would complete a test that was the same as the test in experiment one, a short answer test. The second half of participants took a test that required them to use the concept mapping method to show their knowledge of the material. By applying this change Karpicke and Blunt (2012) ruled out the possibility that by using a final test that was similar to the retrieval method of study(like in experiment one) they were giving the retrieval students an advantage (Karpicke & Blunt 2012, pp. 773-774). The findings of this second experiment also showed that the retrieval method was a more successful study technique for long-term retention, replicating their results in experiment 1. Even in the test that required the students to use concept mapping, the material that was studied using the retrieval method was evidently more successfully retained. It was found that, “Overall, 101 out of 120 students (84%) performed better on the final test after practising retrieval than elaborative studying with concept mapping.” (Karpicke & Blunt 2012,

In his short story “Reading the Paper”, Ron Carlson uses the technique of switching between a normal morning routine and unexpected tragedies to show that the story is truly about reading the paper. After completing some of their morning tasks, such as doing the wash or getting timmy ready for school, the narrator hears someone knock on the back door. When the narrator opens up the door and sees a guy who had just escaped from prison, the escaped prisoner asks “if he can come in and rape [them] and cut [them] up a little bit”(1). Instead of being affected by this at all, the narrator then says, “after he does that, my coffee’s cold, so I pour a new cup”(1). This switch between experiencing a horrible event and continuing their morning routine of getting coffee isn’t normal.

I could recall nearly every detail from those questions, and the answer choices they provided. When I look them over after the test, I can answer all of the questions without hesitation. But when it comes to figuring out how to move on and ultimately become content, I draw a blank, just like on that day of the test. The pattern stays static, and though I do well on tests, I desire perfection, that cherry on top to cement that I know the material in and out. That has been my mentality to as far back as I can remember.

By doing so, we can rely on assessments that allow students to practice and apply material in order to foster retention and mastery (Ravitch 261). Ravitch discusses Finland and how they completely reformed their educational system into a structure that has students take zero standardized tests until they reach the college application process, a method that was enacted to promote teacher accountability and place a stronger emphasis on the noncognitive aspects of individual development. A component of the basis for the argument, Ravitch states, is that while standardized testing may be effective when it is administered fairly, it often impairs students’ abilities to critically analyze information and leaves them practicing how to guess the “right answer.” Addressing this issue is a responsibility that falls on administrators and policymakers; they must be held accountable and required to make changes that best meet the constantly evolving needs of the students. In this case, completely modifying the concept of standardized testing is a necessity.

In this article, Klein argues that companies are no longer focusing on the making of their products but instead on their reputation; it is about selling this idea, an image, a dream, or a fantasy. Companies like Nike don’t make their own products, but instead they send someone else to do it. Companies send their contract to foreign factories, which they don't own, that will produce the product for a cheap price. Additionally, those factories send the order to other organizations that will do it for a cheaper price. Overall, this is how companies make most of their profits.

What is the point of going to school and memorizing lessons that we will forget after the test if they don 't stick to our brains? We need to be knowledgeable, persistent, self-driven to make sure we ourselves understand the lesson at hand. Test affect a student 's self-confidence as well, if we pass it 's a win-win but if we fail we lose a little bit of hope we had about what we knew. We doubt ourselves and that is not a pleasant

Concept attainment is an inquiry-based instructional strategy that is suitable for teaching notions that have an open set of attributes. Concepts have a name, a definition, examples, and critical attributes or characteristics. They are also ideas or abstractions that are formed by putting data into observable categories (Lemlech, 2010). The primary point of this model is to allow students to create their own definitions and understanding.

The more important the information the more likely the individual will be able to recall that information later. However, the meaning is placed on the information itself and not on how the information obtained, as with the behaviourist approach. Cognitive learning theories deal with the issue of how people process and store information to gain an understanding of themselves and the environment, and how their thinking and reasoning influence their actions and reactions (Henson and Eller,
