The NAPLAN Test

Superior Essays
Introduction
The NAPLAN test (http://www.nap.edu.au) is for both primary and secondary schools to assess the performance of Australian students against minimum national standards (Reys et al., 2012). With this in mind the approach to answering the questions was to work through all parts of the questions just like a student would, to form an understanding of the process and methods a student taking the test would perform. The questions were not overly difficult to conceptualise, however, working them out practically was challenging, as being out of a classroom for many years I am able to use mental computation effectively to solve many equations without writing them out. Thinking like a student taking the test allowed me to improve my own practical

ACARA (n.d.) requires students in senior secondary schooling to be able to solve problems related to measurement and scale drawings. Although this scale is not a difficult scale, it is quite apparent the differences in units of measurement would make this problem seem harder that it actually is. While students at the senior school level should be able to solve this, other lower secondary schools should not have too much trouble. According to Reys et al. (2012) children become familiar with units of measurement and even simple multiplication and division in the earlier years. This emphasises that although scale drawings as a whole are implemented into the curriculum in senior schooling the elements of mathematics used to solve the problem are introduced sooner which combine to allow the student to reach an answer. Whilst first examining the question it was apparent immediately that dividing the scale drawing by itself down to one enabled the scale to be reduced to a smaller size. Then by dividing the computer chip size of 8mm by four, which is the same amount that was divided by the scale, this equated to two. Thus giving the answer to confidently acknowledge that 1cm represents 2mm. Another way this could be solved was to multiply the answers in centimeters by the …show more content…
Although challenging at first glance, the resources used since the unit had begun were imperative to solving such an equation. The Helping Children Learn Mathematics textbook (Reys et al., 2012) revised the theoretical aspects of algebra, whilst the https://mathspace.co/ website enabled a practical element in regards to algebra strengths and weaknesses. The first objective to the question was to break down each part of the equation and then see how it relates to the answers. Multiplying ‘n’ by itself represented ‘n x 2’ which in algebra is ‘n2’, then it was simply continuing the equation by dividing that number by two as a way to half it and then subtracting ten. Once I had done this I was comfortable with the answer. ACARA (n.d.) identifies that in Year 7 students should be confident in the concept of variables being able to represent numbers using letters. This highlights the importance of gaining an understanding early, as all that is needed in a question like this is to recognise the arithmetic needed and how they work in an algebra context. Another way of solving the problem was not apparent other than working from back to front or the process of

    The complexity of proof in primary school changes as children progress through different key stages, there is seen to be a huge change of proof in secondary schools compared to primary school. Proof has received a prominent role in Maths for secondary school, a key part of all student’s Maths experience (Knuth, 2002). However, it is still included in the primary curriculum just with more depth in secondary schools. Primary school children may not be able to explain their Maths conclusions in depth by a means of formal proof but they can begin to demonstrate and clarify why something is true to then reach a valid proof (Haylock and Manning,…

    In this study, interleaving worked best because it taught students to read each question and properly identify what strategy they should use. The reason blocking was not as effective was that students no longer need to decipher which strategy to use. This is due to the fact that when they figure out the strategy for question one, it will be the same strategy they use for all ten questions. When it came time for testing, either one or thirty days later, the students who were able to identify the differences between the questions, the students in the interleaved practice condition, were more successful in solving the math problem because they developed the strategy for solving each…

    Summary I gain a lot of insight and learning from going through the process of identifying a student, getting to know them, administering a variety of assessments, writing about and interpreting the test results, researching interventions and supports, and making recommendations based on all of the information collected. My two main takeaways are that I had some difficulties with Woodcock Johnson IV assessment and that I significantly changed my mind about the pedagogy of math. I struggled with administering and interpreting the Woodcock Johnson IV. While I was administering the test it was difficult to just follow the script and not prompt the student to think about the question longer or review their work before they had a final answer.…

    I will be able to see if they a learning the math I am teaching them and if they are progressing on all other areas that they need for First Grade. Not relying heavily on tests allows my classroom to have more creativity. Assessments are important, but they are also easy to use throughout the whole day while the students don’t even realize they are being…

    Since the late 1990’s and early 2000’s the USA has struggled to keep up with the rest of the world in the fields of science and math (Olszewski-Kubilius). STEM classes will help change these facts. Giving students the chance to have hands on and active learning will help students gain and retain the knowledge they learn in class (Morrison). Not only that, but when students retain the knowledge that they have gained they will start to do better on tests. With both the ACT and SAT having a science and math portion available to take these classes are even more important.…

    They are able to create mental pictures and manipulate images in their minds. Montessori math materials help children form these intellectual images to adapt to the concepts and skills. The child will repeat until they feel there is no need to repeat activities for the sake of repetition, because they have learnt it. The elementary child requires materials which offer repetition but with more change. As the Montessori preschool student moves closer and closer to having an abstraction way of learning, the need for the child to use the materials for a long time shortens.…

    The pragmatic way of problem solving was most evident in mathematics as the math curriculum I was using emphasized thinking and problem solving. My students were exposed to real life problems and with just a little guidance from me, they were able to think and solve complex math problems. My teaching matched the expectations of that of John Dewey as I encouraged children’s open-minded curiosity and fought against stifling it with routine and dogmatism. (Gutek, 2014). Over the next ten years or so, I successfully employed this method of teaching students.…

    Additionally, those processes support students when solving problems and guides them to understand the Maths they are learning and using (Carpenter et al., 2003; Lannin, Ellis, and Elliott, 2011). These specific methods used in mathematics are evident in the 2014 national curriculum for Mathematics. The national curriculum states how all pupils should reason mathematically following a line of enquiry, conjecture relationships and generalisations, and develop a proof using mathematical language (Department for Education, 2013). The current national curriculum has shown a massive change in the use of proof in the classroom from when it was first heavily introduced in both primary and secondary schools (Waring, 2000). Proof has become more emphasised in the national curriculum over the past years because children are now required to be fluent in Maths with a deeper understanding and have the ability to reason mathematically to reach conclusions, especially since the introduction of the mastery…

    The findings showed an improvement on students’ mathematical thinking through math communication, increased use of mathematic vocabulary, and math journals can also be used as an assessment tool (Kostos & Shin, 2010). The pre and post assessment that was administered to the sixteen students showed one student’s score remained the same, one’s score decreased, but there was an increase in the overall score of the remaining thirteen students. There was also significant growth in the students’ journal writing scores initially five students scored zero, six students scored one, and four scored two out of a total of two points. However, by the second entry no student scored a zero, and as the weeks progressed the researcher notated the students’ details, verbiage, and step-by-step explanations were much better too. Therefore, Kostos was able to conclude there was an improvement of students’ communication of mathematical thinking (Kostos & Shin, 2010).…

    Similar to words, numbers are like another language and it is important to help a person grow in society. Numbers are symbols which we use to help us think and give us an idea like a sentence would. Montessori along with many other theorists understood that if mathematics was introduced to a child from early stage in their life, it would grab the child’s attention through their sensitive period. Montessori also knew that Mathematics is not difficult for anyone once it has been taught properly. Even in today’s era numerous shared worries linking to maths are a result of the child being requested to carry out abstract calculations too soon, instead of being able to work at their own pace.…
