The academic article investigated in this research is called ‘The Economic Value of Higher Teacher Quality’ (Hanushek 1). This academic writing describes the correlative relationship between the teacher performance and the further performance of the student focusing on the upcoming future economic achievements of each individual. The economic outcomes of the teacher quality are used as a basis for evaluating the influence and the connection tightness between the teacher quality and further growth of the student computed in the US dollars. The results of calculation demonstrate that the standard deviation of a teacher performance corresponds to the marginal income of $400,000 (present value) in a class of 20 individuals. The investigator finally arrives at the conclusion that replacing the bottom ‘bad performers’ (approx. 5-8%) is going to result in a significant economic push for the American economy that is estimated in $100 trillion. Certain attention was also paid to the problem of salary-based motivation and its effectiveness for the improvement of the teacher performance. Certification, salary policies, and school differences are described. Hanushek discusses the need for the idea development in the sphere of teacher labor market and salary level that is “economically desirable” (24). He also states that the lack of information on teacher labor market and potential pay systems do not allow developing a deeper insight in possible solutions. However, Hanushek still recommends creating a closer link between teacher quality and salary (26). 

The corresponding media coverage was delivered by CNN and represented in the form of interview with Steven Perry, an education contributor and PhD from the University of Hartford. The video interview was supported by a short summarizing article in CNNblogs.com called ‘Perry's Principles: Students learn three times less from bad teachers’ (CNNblogs.com). Evaluating the accuracy of the media interview in this case, the researcher finds out the simplicity of data and conclusion representation. Unlike the original academic article, the media broadcast was a lot easier to grasp at once because the entire complexity of the problem was summarized in several simple ideas. The figures demonstrated were cut to minimum but still there was left some impression of long-term academic work that stands behind these findings. The language used in the interview was also a lot different – informal and even colloquial at times. Evidently, all the figures and complex calculations in ‘The Economic Value of Higher Teacher Quality’ were simplified and replaced by the orator’s emotional speech in the interview and major statements that are very easy to comprehend in the short CNN blog post with the attached video (CNNblogs.com).

Probably the main difference between the original article by Eric Hanushek and the corresponding CNN interview was the emotional appeal. The first paper was called to persuade the reader’s rational thinking, while the interview was obviously intended to ‘hook-up’ the viewer due to the expressive techniques. This also affected the accuracy of the coverage in some ways – while the academic article was more focused on teachers’ work and all related aspects (labor market, salary, policy shifts, etc.), the interview was more concentrated on general public implying students, their parents and relevant interests. There was no significant contradiction between the original piece of writing and its discussion in the media, but still, these two representations are very splitting in the forms and ways of delivering information.
