Validity of Main Intelligence Tests

Validity of Main intelligence activity TestsNowadays, it is getting more(prenominal) and more people comparing self to others in order to define their standards among the other. withal of comparing achievements and richness, acquaintance is one of the most popular items to be compared. engraft on the watchword oodles, people get to prejudge and define others this whitethorn cause people with low intelligence stigmatizes withdraw from socialise and other psychological problems. Intelligence is the ability to solve problems, or to shape products, that are valued within one or more heathenish settings (Gardner, 1993, p. 33). The purpose of this paper is to cartoon whether the main intelligence analyses are reasoned esteems of peoples ability to perform intelligently. According to the past researches, it is found that the main intelligence tests such as Ravens modular reformist Matrices, regulation-Binet Intelligence racing shell, and Wechslers tests are sensible to call in peoples schoolman achievements (Freberg, Vandiver, Watkins, Canivez, 2008 stuff, Fiorello, Kavanagh, Hoeppner, Gaither, 2001 Pind, Gunnarsdottir, Johannesson, 2003 Rushton, Skuy, Bons, 2004 Smith, Martin, Lyon, 1989).One of the studies which found that Wechslers tests are sensible measures in predicting peoples faculty member achievements was do by Freberg et al. (2008). The aim of the ponder was to examine the cogency of Wechsler Intelligence Scale for Children Third Edition blanket(a) Scale IQ scores in measuring approaching academic achievement establish on the satisfying difference among the WISC- tether four divisor scores emancipation from Distractibility, Perceptual Organization, Verbal perception, and impact Speed (Freberg et al., 2008, p. 135). The landing field was participated by 202 students who were assessed double over three years for special education qualifications. Participants age ranged from 6 to 13 years. Participants were divided int o two groups according to the absence or bearing of a significant variability between the WISC tether four conveys scores, and then the WISC III four factor scores were matched across groups on Full Scale IQ scores, sex, age, ethnicity and harm such as special acquirement disability, serious emotional disturbance, and mental retardation.In the battleground do by Freberg et al. (2008), the results were analysed by using hierarchical multiple regression showed that the WISC III Full Scale IQ was a logical measure of edition achievement (r = .65) and math achievement (r = .75) in the occurrence of significant factor score discrepancy. The results of this field of operation support present argument because Freberg et al. (2008) found that WISC III Full Scale IQ could be a powerful and legitimate predictor of future academic achievement, where the higher the IQ score, the better it is in variant achievement and math achievement. However, the sampling size in this study w as too small to generalize the result to every aspect, so it is recommended that future research should be do with larger sample sizes. Besides, this study pore solely on the WISC III, which could be replaced by WISC IV, due to this limitation, it is suggested that this study should be replicate by using WISC IV or different gracious of cognitive ability test to examine the generalizability of this study.Besides of the study done by Freberg et al. (2008), there is another study done by Hale et al. (2001) as well found that Wechsler Intelligence Scale for Children Third Edition is a valid measure to predict childrens academic achievement. There were 174 children who age ranged from 6 to 16 years participated in this study. In order to be involved in this study, they call for to complete the 12 subtests to analyse factor scores and WISC III Full Scale IQ. Other than that, they needed to have Full Scale IQ between 80 and 120, and to have a significant discrepancy between log ical or rational functioning and no less than one academic achievement area. Children were not include if they had a record of epilepsy, brain injury or all other checkup condition that would affect psychological functioning. Archival data of 6-year period were peaceful to examine the presence and absence of medical histories.According to the results in the study done by Hale et al. (2001), it showed that Full Scale IQ was positively correlated with all the academic achievements Verbal Comprehension (r = .68), Reading Comprehension (r = .33), Reading Decoding (r = .33), Spelling (r = .39), Written Language (r = .33), and Math ready reckoner science (r = .44). The results of this study support present argument Hale et al. (2001) also found Wechsler Intelligence Scale for Children Third Edition as a valid measure to predict academic achievements such as verbal comprehension, reading comprehension, and math computation. It means when the children score higher in Wechsler Intelli gence Scale for Children Third Edition, it is predicted that the children can also score higher in academic achievements as mentioned above. This study used a clinic-referred sample of children with acquire disabilities, so the results in this study may not be generalized to school-based samples of children with learning disabilities or normal children. Thus, future studies could look at whether the same functioning patterns present for different group of populations.Apart from Wechsler Intelligence Scale, Ravens Standard modernised Matrices is also one of the main intelligence tests. A study done by Pind et al. (2003) found that Ravens Standard Progressive Matrices is a valid measure to predict childrens academic achievement. In the study, participants that were rattling assessed were 665 children who age ranged 6 to 16 years, but it ended up only 550 children were chosen to the actual alike(p) sample. The tests were run as group tests in a group of 10 children. Administrator was in the classroom to describe and to guide the children throughout the tests. To declare sure coding of the answers accurately, every test form was keyed into computer twice. According to the results, Ravens Standard Progressive Matrices had higher positive correlation with maths as compared with the positive correlation of Ravens Standard Progressive Matrices and language subjects. Besides, Ravens Standard Progressive Matrices also had remark competent positive correlations with the Icelandic National Examinations in fourth grade (r = .38), seventh grade (r = .64), and tenth grade (r = .53). The results of this study support my argument because it testified the usefulness of Ravens Standard Progressive Matrices to measure intelligence and to predict students academic achievements in Icelandic National Examinations, where the higher score the students got in Ravens Standard Progressive Matrices, the higher they could score in Icelandic National Examinations.Not only Ravens Sta ndard Progressive Matrices is a valid measure to predict academic achievement, Rushton et al. (2004) found that Ravens sophisticated Progressive Matrices is also a valid measure in predicting academic achievement. There were actually 392 students from University of the Witwatersrand took the Ravens Advanced Progressive Matrices, but it was cut down to 306 students by not including those without biographical data, high-school grades, or examination scores, or those who listed their age that over 23, or those who were in a small sample sizes. One hundred and cardinal seven of them were Africans while another 129 were non-Africans, their age ranged from 17 to 23 years. Ravens Advanced Progressive Matrices and other academic tests were administered by authors and his colleagues during regular class period. Students authentic 50 rand each as reward when they passed up the answer sheets. ground on the results in the study done by Rushton et al. (2004), for the Africans, results indicate d that Ravens Advanced Progressive Matrices correlated positively with English Test (r = .29), Similarities Test (r = .14), and High-school Grade presage Average (r = .22). While for the non-Africans, Ravens Advanced Progressive Matrices also correlated positively with English Test (r = .25), Similarities Test (r = .26), and High-school Grade Point Average (r = .16). unlike to expectation, Ravens Advanced Progressive Matrices was not correlated with University Grades either for Africans or non-Africans. The results of this study support present argument because Rushton et al. (2004) examined the validity of Ravens Advanced Progressive Matrices which indicated that it is a valid measure to predict academic achievement although it failed to predict University Grades. It was mentioned that Africans were notSmith et al. (1989) did a Stanford-Binet Intelligence Scale Fourth Edition verification study on predicting academic performance. This study compared and assessed the performance of students with learning disabilities on the Kaufman assessment stamp battery for Children and the Stanford-Binet Intelligence Scale Fourth Edition. The sample included 18 students with learning disabilities who ranged in age from 8 to 11 years. all student was diagnosed before as having learning disability by fetching intelligence test individually. Every student was arranged to take the Kaufman Assessment Battery for Children test and Stanford-Binet Intelligence Scale Fourth Edition test in counterbalance sequence by psychologists in school. The time worn out(p) between tests was 5 to 22 days, with an average of 12 days.Results in the study done by Smith et al. (1989) showed that the Kaufman Assessment Battery for Childrens Mental bear upon conglomerate was positively correlated with Sequential Processing (r = .77), Simultaneous Processing (r = .92), and Achievement (r = .48), while Stanford-Binet Intelligence Scale Fourth Editions Test Composite was also positively co rrelated with Verbal Reasoning (r = .96), Abstract or Visual Reasoning (r = .89), and Quantitative Reasoning (r = .78). These results indicated that Kaufman Assessment Battery for Children and Stanford-Binet Intelligence Scale Fourth Edition are valid measures of students with learning disability to perform intelligently. The results of this study support present argument because Kaufman Assessment Battery for Children and Stanford-Binet Intelligence Scale Fourth Edition also found to be valid to predict academic achievement positively. The limitation of this study was the sample of participants. As relationship between intelligence scales and academic achievements were examined in this study, participants were needed to do sure solving problems, reading, spelling, or writing questions, thus, students with learning disabilities susceptibility not be able to solve or answer rough of the questions which would affect the results. Therefore, future researches are needed to examine the generalizability of the results for different samples of students with learning disabilities.As a conclusion, main intelligence tests such as Ravens Standard Progressive Matrices, Standard-Binet Intelligence Scale, and Wechslers tests are found to be valid to predict peoples academic achievements (Freberg et al., 2008 Hale et al., 2001 Pind et al., 2003 Rushton et al., 2004 Smith et al., 1989). According to the scores from intelligence scales, academic achievement might be able to be predicted however, it does not mean people can get the good result without paying certain amount of efforts on getting impressive results. Therefore, intelligence scales can be good measures or tool to predict how well is the people able to achievement, but it cannot assure the prediction if the person does not pay any effort.
