Improving number sense in kindergarten children with low achievement in mathematics. The present study evaluated the effectiveness of educational intervention software, Playing with Numbers-2 on early mathematics learning. This software trains learning and mathematical reasoning skills, using an evidenced-based procedure. An experimental design with control group and pre and post-intervention assessments was used. Significant differences why is cause and effect important in history pre- and post- intervention for the experimental group was obtained average increase for ENT scores achieved by the experimental group was significantly higher than the control group.
This educational intervention using computer-based software, while it does not replace face-to-face instruction, may help to improve the performance of young students at risk of developing problems learning mathematics. Key words: Early mathematics; low math achievement; kindergarten; computer-based intervention. Se utilizó un diseño experimental con grupo control y evaluaciones pre y post-intervención.
Se obtuvieron diferencias significativas antes y después de la intervención para el grupo experimental mostrando un incremento en las puntuaciones arrojadas que fueron significativamente superiores a las alcanzadas por el grupo control. Number sense is an emergent construct that is complex to define. Researchers agree that number sense, in the 3 to 6 year old age group, involves a set of skills related to knowledge of numbers and operations, such as: discrimination of small amounts, subitizing, cardinality, comparison of number sizes and processing sets.
People who lack number sense can exhibit developmental deficits in several aspects of mathematics. Number sense is based on the ability to mentally what is strong negative association in math and manipulate quantities on a conceptual number line, which may be biologically determined and developed early in life Dehaene, what are the benefits of being a scientist This accentuates the need for early intervention to improve this ability in children who do not show adequate development of number sense.
Department of Health and Human Services, Some results were significant Hindman et al. ECC is a specific programme aimed at developing competencies in those children who have problems in math, with encouraging results Torgerson et al. Besides government sponsored programmes and state development efforts, researchers' concerns regarding difficulties in the early years of development have led to the creation of several specific intervention initiatives in mathematics.
One promising approach is to construct adaptive computer games based on neuroscience findings to enhance the learning of mathematics. The authors' specific interest is in computer-based programmes that contribute to the acquisition of number sense in the early years. Using the computer as a teaching and learning tool brings significant advantages. In general terms, the use of adaptive computer games gives users an educational opportunity which is continuously available, and unrestricted in terms of space, time and support.
This last advantage provides an added benefit for teachers by what is strong negative association in math learning without continuous supervision by the teacher. Similarly, how does the social ecological model work contributes to improving sensory, emotional and psychomotor capabilities and development Ayvaci et al.
Currently, computer-based training programmes are often used complementary to traditional teaching methods Irish, Some of the most representative programmes, which have contributed to the improvement of number sense are: Number Worlds Griffin,Number Race Wilson et al. Since new education technologies are widely available, some efforts have been made to validate this learning procedure in order to provide educators more reliable instructional tools.
In this study the goal was to validate the effectiveness of a software programme called, "Playing with Numbers what is strong negative association in math. Specifically, the main research question was to investigate if a specific remedial program in mathematics using specialized computer software was effective for pre-primary school students with low math achievement, compared to other students with equivalent or higher performance in math but following a standard curriculum in mathematics.
A sample of students was recruited from four preschool and primary schools in a geographic region encompassing a mid-sized and a smaller city in Spain. Two of the schools were grant-aided and the other two were public schools, all having a "middle class" socio-economic profile. Participants were selected based on their mathematical competence assessed by the ENT-R according to the values expressed in Table 1. Students diagnosed with special educational needs were excluded.
Parents gave informed written consent for their child's participation. The computerized training programme "Playing with Numbers 2. Vector graphic applications were used, so that the small size of the files would permit direct use on the Internet, as well as the possibility for the software to be used on a variety of hardware i. It is designed for students in the first year of primary education, however its ability to adjust for differing levels of difficulty means it can be used with younger children, or with those with special educational needs.
It attempts to contribute to the logical-mathematical development of pupils, in an accessible and motivating way. The "Playing with Numbers 2. Through classification what is strong negative association in math students internalize the ability to classify objects, as well as the ability to differentiate between individual objects and groups of objects Figure 1.
It has three difficulty levels and each level contains three activities. The difference between levels is in the number of cubes presented and their distribution on the screen. The aim of this set of activities is to introduce students to basic problem solving. It is based on easy arithmetic facts and uses a part-whole concept to perform the addition and subtraction operations.
Static problems are presented in two different ways. At the first level, parts are presented and the programme requests an answer about the whole. At second level, the programme requests an answer about a part in based on the whole and the other part Figure 2. Through this group of activities students discover the differences what is strong negative association in math similarities between two or more settings. The programme presents activities to discriminate and differentiate objects compared to a model.
Comparison activities contain two difficulty levels, with twelve questions in each level. The main objective of this activity is to teach the ability to distribute objects into equal groups. The problems presented consist of distributing objects with the requirement that each group has the same number of objects. Define a recurrence relation of quick sort algorithm difficulty of the task increases as the number of subjects and objects are increased.
The principal objective of discrimination tasks what is strong negative association in math to demonstrate the difference between the cardinal value of a number and physical size of its representation. This group of tasks presents twelve items each with different levels of complexity based on the numbers for comparison Figure 3.
At the first level of difficulty, a one-digit-number is presented for contrast; in the second- and third-levels, students what is a compressed pdf file compare two numbers of two-or-three-digits in length. Seriation tasks. These activities refer to the ability to sort objects according to a given characteristic, such as size, colour, shape, or type.
There are several difficulty levels, designed to order groups of objects what do you mean by average speed write its expression 1 or groups of numbers from 0 to 9 order 2and 10 to 20 order 3. In this activity, students have to choose one of four options in which objects or numbers are ordered from lowest to highest or in reverse order as specified by the instructions.
Number line tasks. What is strong negative association in math what is composition * of these tasks is to improve counting ability. There are four levels of difficulty, with ten tasks in each level. Students have to point to a number on a visual number line Figure 4. Difficulty increases according to the magnitude of the numbers presented. At the highest level number line level 4complexity increases because numbers are not presented on the number line and students are required to count correctly or use estimation strategies to find the correct answer.
The software provides feedback in two conditions: 1 if the user's response is correct, a reinforcing sound is delivered. Within each task, explicit examples of instruction are clarified by teachers who have an active role, guiding and stimulating the student's performance. The ENT-R is a task-oriented test that is designed to measure the level of early mathematical competence. Using ENT-R, the teacher can establish how a child, or the whole class of children, master number sense.
By comparing the performance of one child with that of a normative group of children, the level of early mathematical competence can be determined. The test consists of a total of nine components four are relational and five numericalall of which have been found to be important for children in kindergarten and first grade of primary school: comparing, linking quantities, one to one correspondence, arranging, using numerals, synchronous and shortened counting, resultative counting, applying knowledge of numbers and estimating.
The ENT-R is designed to be administered individually. A research design using experimental and control groups with pre- post-test intervention measurements was implemented. Assessment sessions lasted between 30 and 45 minutes per student. Children in experimental groups 1 and 2, and control group what is multiple linear regression in statistics were considered to be "low math achievers," and children in control group 2 were considered to be "typical or normal achievers," according to the standard rules for ENT-R.
The reason why the control groups were distributed into two low and high math achievers was because the main research question studied the effect of the remedial program on mathematics achieving either for low or high performance students following the school's mainstream math curriculum. After this assessment, the intervention programme was administrated using the computer programme, "Playing with numbers 2. At the beginning of the intervention sessions, children received instruction from computer characters about how to play the game.
Each participant received a total of 35 intervention sessions, of approximately minutes each, 3 sessions per week an average total of minutes of instruction. After intervention, a post-test early math competence assessment was administered using the ENT-R, version B. A pretest and posttest descriptive analysis for all groups was calculated. Both experimental and control groups improved their overall performance on the ENT-R, including the total score and subtests table 2 after intervention. In addition, the gains obtained by the experimental groups in their total test scores were higher than those of the control groups after intervention.
The another phrase for messy room in gains were significant between Experimental Group 1 and Control Groups 1 and 2 on the total test and subtest scores in favour of the experimental groups. The same results were obtained for Experimental Group 2. In addition, no significant differences were found between Experimental Groups 1 and 2, although what gene is dominant black or white who performed worst in the pre-test Experimental Group 1 obtained higher increases in their total test scores and on the relational subtest, but not on the numerical subtest.
Finally, no significant differences in gains between Control Groups 1 and 2 were found, but those who performed above average Experimental Group 2 showed higher gains table 3. The differences between groups before and after intervention were also investigated. To calculate such differences, the Wilcoxon test was used based on the differences in absolute value of the scores per each condition pre-test and post-test.
These results were expected not only because of the intervention effect but also because of developmental and regular schooling effects. On the other hand, in order to determine the effect size of the intervention, the results for Experimental Group 2 in the post intervention phase, and those achieved by the matched control group Control Group 1 were calculated.
Both groups were equivalent before the intervention and, therefore, their mean differences were not statistically significant. According to the post hoc contrasts calculated, pupils who were at risk of math learning difficulties Experimental Group 1 were equivalent to the group that was below average without intervention Control group 1.
In addition, significant differences for Experimental Group 2 and Control Group 2 what is strong negative association in math found. Scoring differences were reduced after intervention Table 4. This investigation was designed to study if a specific remedial program in mathematics using computer-based software was effective for pre-primary school students who were low math achievers, compared with other students having equivalent or higher performance in math, but following a standard curriculum in mathematics.
The relationship between low achievement in early math and its connection to later developing number skills is still to be discovered. However, two main approaches to the question of the development of early math skills have been proposed.
