Can Eighteen-Year-Olds Use Their Right to Vote Reasonably

Can Eighteen-Year-Olds Use Their Right to Vote Reasonably? When people reach the age of 18, they plunge into a world of new opportunities and liabilities. From now on they are considered full-fledged members of society with all that it implies: they can take responsible posts, marry, and do everything that is not prohibited by law. They start to make important decisions considering their life and future and start to learn how to live independently. That is, of course, the best course of events, but it is not always so. All the people are different, have their own characters and destiny. That is why not everyone is ready to live on their own at this age. They can’t be blamed for it, as that is their nature. To my mind, at this moment it is better for a person to start thinking over their future life and preparing foundation for it. Each person at the age of 18 has gained enough knowledge and skills to do it, but not everyone wants to, and that is a personal matter. Anyway, at this age we can witness a mature personality and even he/she is not able to take independent decisions – there is no guarantee that at the age of 25 he will be able to do it. Thus, this age is an important milestone of people’s life, when it is clear what a person really is and what he/she can achieve in several years. Thus, I think that this age is absolutely appropriate to start voting. Those who have already formed a strong personality and know what they want from life can really make valuable contribution into nation’s choice, while those who are still not mature enough probably will not be able to make such choice in 5 years as well.

A Dual Immersion Program For Hispanic Children From...

This quarter I am continuing my observations with Heather Cyrus from Barbour Dual-Language Immersion Academy. She is a unique second grade teacher for Spanish and English speaking students. In my prior fieldwork assignments, I have not met another teacher who has been so ahead of her peers in evolving the classroom for successful, 21st century education. Barbour runs a dual immersion program for Latino children from kindergarten through eighth grade. Starting in the lower grades more Spanish instruction is the main concentration with English incorporated more and more each year. The classrooms are split as evenly as possible with English speakers and Spanish speakers of all backgrounds and ethnicities. The average class size is 26 students†¦show more content†¦Her philosophy of learning is â€Å"ever changing† and she believes â€Å"the learner is the most important piece of the puzzle†¦Ã¢â‚¬  . (H. Cyrus, personal communication, January 20, 2017) She works continuously with the other second grade teachers in a team to set the plan on the standards and how they will meet them each year. They do not follow a curriculum, but the Common Core State Standards (CCSS) with the Essential Learning Outcomes (ELO) and Depth of Knowledge (DOK) levels. The curriculum Math Investigations is offered in the district for her gr ade level, but it is not a main focus for her lessons. She utilizes curriculums provided by the district as resources and supplements for lessons alone. When sitting down with her fellow teachers, they do what’s called â€Å"unpacking† the standards. Project- based lessons are built in putting as many subjects in to the units as possible. With ESL students, vocabulary is a large part of their unit design and plays a significant role in Spanish or English in teaching students to understand the lessons. There are pretests devised based on these objectives and units for each teacher to determine the needs of their students in their particular classrooms. Like most teachers, she supports the CCSS but does acknowledge the flaws of their implementation. In our interview Heather tells me, â€Å"the CCSS are not developmentally appropriate, †¦often times social/emotional standards are less emphasized, †¦ the amount of CCSS we often are

Metamorphic Testing Alleviate Oracle Problem

Question: How Effectively Does Metamorphic Testing Alleviate the Oracle Problem. Answer: Introduction Primary context of the paper is to emphasize over the Metamorphic testing efficiency and effectiveness for reducing the Oracle problem. In this critical reviewing, the article is identified as How Effectively Does Metamorphic Testing Alleviate the Oracle Problem? by Huai Liu, Fei-Ching Kuo, Dave Towey, and Tsong Yueh Chen. Oracle is identified as something that can vary the test case appropriateness results. In case, the Oracle too expensive for using or does not exist, and then Oracle problem occurs. Now, the authors purpose is to depict the metamorphic testing as an approach of helping appropriateness of a program. The purpose is justified for experienced testers with smaller amount of testing required. The author needs to cover the testing expertise for writing the article. The thesis statement is to study metamorphic testing for redacting Oracle problem. The researcher agrees with the thesis statement as it demonstrates the appropriate way to reduce the problem. Summary Metamorphic testing is identified as the testing procedures with various applications in certain domains as successfully recognizing the faults in programs. There were some studies to establish suitable guidelines in test Oracles. The study is conducted to identify suitable prior studies and related works. Therefore, the study is carried forward with secondary approach following article reviewing, journal studying, and relevant work analyzing. The prior studies show that Oracle problem can be taken into consideration with formal algorithm procedures as finite state machines. Compared to other methods, metamorphic testing is generic approach. Moreover, the assertion technique is embedded within source code for detecting bugs while execution. On the other hand, multiple versions of program can be utilized for reducing the Oracle problem. The technique is identified as N-version programming as it is designed to be fault tolerance technique. Mutation analysis technique is suitable someti mes with constructing the test Oracles. It is more of a unit testing along with list of assertions. Hence, from the secondary studies, the research questions are identified as following: RQ1: How effectively can metamorphic relations detect software faults? RQ2: How capable are testers of alleviating the oracle problem using metamorphic testing? RQ3: How the cost-effectiveness of metamorphic testing can be optimized? The study was carried out to depict the metamorphic testing relation effectiveness for detecting software faults and bugs. Moreover, the study is elementary for identifying the capability of testers for reducing the Oracle problem along with metamorphic testing. Furthermore, metamorphic testing can be cost-effective or not is another research aim to be achieved. The author is proposing the research questions in form of hypotheses as with positive or negative considerations. The positive and negative consideration is proposed for making the study empirical along with meeting the objectives. Author is proposing that metamorphic testing have fault-detection effectiveness for reducing the Oracle problem. The author will assess the metamorphic testing with qualitative approach for identifying how many metamorphic relations are required to reduce the problem. Again, the in-depth analysis of metamorphic testing is performed for assessing metamorphic testing relations, overall performance, and tester capability evaluation. For the thirds research question, the study identified some important factors as a way to understand possibility to optimize the cost and effectiveness of utilizing metamorphic test procedures. Now, the study is mostly qualitative, analytical, and secondary study based. On the other hand, there is an experiment conducted for subje cted programs, mutant generation, metamorphic testing relations recognition, random testing whether with or without that particular problem and test case preparation. The experimental results are identified as detection of real-time faults as in MultipleKnapsack and Sparse-MatrixMultiply programs. However, the testers have recognized the faults with metamorphic relations. Again, the prior studies of metamorphic testing shows that popular Siemens suite have such real-time faults as well. Now, for first RQ, the hypothesis significance is viewed as 0.05 and p-value is lower than significance value, resulting in rejection of null hypothesis (H0). As per the results, there were 19 metamorphic relations and each of them has outnumbered the RT with 90% of difference in between the RT and RTo. Now, (6 + 10 + 8 + 12 + 19) / 99) that is 55.56% have fault-detection values between RT and RTo. In case of using all metamorphic test relations, the collection was identified with another way to regard them for imitation of test Oracle. The fact is identified as a smaller amount of diverse metamorphic relation is adequate to match the fault-detection showing intuit ively appealing results. A team of 4 to 7 testers can easily identify the metamorphic relations for similar detection of faults to test oracle. Moreover, the discussion demonstrates the insights of metamorphic testing for best practice of conducting such testing. Critique The primary argument is identified in terms of setting the hypotheses in the study. The insights are identified in the study with showing how the testing can be properly conducted with best practice adoption. The diversity of metamorphic study can be recognized with important than the quantity. Moreover, smaller team of testers with separate expertise can be effective than larger teams in testing procedures. The researchers have recommended incorporating the testers for diversity consideration for metamorphic test relation selection for testing. The insight presented in the article is strong and it is not open for falsification as the result is justified with significance level of hypotheses. In the article the key words are identified as following: metamorphic relation, software testing, oracle problem, test oracle, and metamorphic testing. Software testing is properly addressed within the study with recognizing the metamorphic testing as a suitable approach. Test oracle is main context in the study as it is depicted with metamorphic testing relations and procedures. Moreover, the oracle is identified as something that can vary the test case appropriateness results. In case, the Oracle too expensive for using or does not exist, and then Oracle problem occurs. Furthermore, the key words are identified in the article following individual evidences of such terminologies from prior studies as well. The authors are Huai Liu, Fei-Ching Kuo, Dave Towey, and Tsong Yueh Chen. Huai Liu is with Australia-India Centre for Automation Software Engineering, RMIT University, Melbourne 3001 VIC, Australia. Fei-Ching Kuo and Tsong Yueh Chen are with the Faculty of Information and Communication Technologies, Swinburne University of Technology, Hawthorn 3122 VIC, Australia. Dave Towey is with the Division of Computer Science, The University of Nottingham, Ningbo, 315100, Zhejiang, China. They have properly established their expertise in preparing the study with metamorphic test relations and related test case generation. Moreover, the authors have selected this particular argument of metamorphic testing to show it cost-effectiveness, fault-detection technique, and overall tester capability. The evidences are identified in the inside and other investigation of transformative testing is performed for surveying changeable testing relations, general execution, and analyzer ability assessment. For the thirds look into question, the study distinguished some critical components as an approach to comprehend plausibility to enhance the cost-adequacy of changeable testing. Presently, the study is for the most part subjective, explanatory, and optional study based. Then again, there is an examination led for subjected programs, mutant era, changeable testing relations acknowledgment, arbitrary testing whether with or without that specific issue and experiment readiness. The test results are distinguished as location of continuous blames as in some JAVA programs. Notwithstanding, the analyzers have perceived the shortcomings with changeable relations. Once more, the earlier investigations of transformative testing demonstrates that mainstream Siemens suite have such continuous blam es also. Presently, for first RQ, the theory importance is seen as 0.05 and p-esteem is lower than criticalness esteem, bringing about dismissal of invalid speculation (H0). According to the outcomes, there were 19 changeable relations and each of them has dwarfed the RT with 90% of distinction in the middle of the RT and RTo. Presently, 55.56% have blame discovery adequacy amongst RT and RTo. In the event of utilizing every single transformative connection, the accumulation was related to another approach to respect them for impersonation of test Oracle. The truth of the matter is recognized as a littler measure of different transformative connection is satisfactory to coordinate the blame location indicating instinctively engaging results. A group of 4 to 7 analyzers can without much of a stretch recognize the transformative relations for comparative discovery of deficiencies to test prophet. Additionally, the exchange exhibits the bits of knowledge of changeable testing for best routine of leading such testing. Conclusion The context relies upon the software testing as well as the Metamorphic Testing for mitigating the impact of Oracle problem. As metamorphic testing is an effective way to test any source code or program with metamorphic relations and testing procedures. The article has offered empirical analysis of the metamorphic testing for reducing the impact of Oracle problem where the testers can detect the problems successfully. Several postgraduate and undergraduate students were taken in the study for quantitative research and identification of knowledge of metamorphic testing. Again, the fault-detection effectiveness is studied with group of testers to link the number of metamorphic test relations in subjected programs. More importantly, the smaller diverse metamorphic relations can identify the most underlying situation of Oracle test. The Oracle testing is based on critical factors as having impact on metamorphic relations. The diverse metamorphic and metamorphic test relations may have fa ult and error detection efficiency for programs and as well within the study.
