First, individual items in Digit Span Forward and Backward were modified so that the numbers 19 were evenly distributed throughout the trials and were also reordered within some items so that numbers with similar sounds (e.g. It was recommended among others that science teachers should vary concentration spans of science students by inherently mimicking the same kind of cognitive gear shift in the activities that require creative problem-solving skills and thinking, Also interventions and accommodation need be designed by school administrators to help science teachers differentiate instruction with explanations on how techniques or strategies can address students with working memory difficulty and attention deficits in the classroom. The WAIS-IV (2008) Digit Span subtest differs from the Digit Span used in all prior studies in two ways. There exist no significant relationship between measure of working memory, attention span and the combination of working memory and attention span of students. Findings revealed that low percentage variation in students’ problem-solving skills in science can be attributed to measure of working memory and attention span. Multiple regression analysis was used to analyse data used to answer the research questions and test null hypotheses at 0.05 level of significance. There are too many variables to cite only one reason for low Digit Span (or any other test on the WISC or WAIS). Wechsler Adult Intelligence Scale (WAIS) backward digit span task and Attention Lapses Clicker (ALC) were used for data collection.
The population for the study comprised all Secondary School I (SSI) that offered physics, chemistry and biology as school subjects in all the public senior secondary schools in the study area for 2017/2018 academic session while the sample was 450 science students from 24 Senior Secondary Schools in the study area.

The study sought to determine the relationship between problem-solving skills and measure of working memory and attention span of science students of low ability level.

Results challenge traditional intelligence nosologies and suggest consideration of a two-step method of WAIS-IV interpretation in clinical samples, whereby the Full Scale IQ score (FSIQ) score is examined first and individual subtest scores are analyzed second.Ĭonfirmatory factor analysis Wechsler Adult Intelligence Scale intelligence measurement invariance psychological assessment.Problem-Solving Skills as Correlates of Attention Span and Working Memory of Low Ability Level Students in Senior Secondary Schools Consistent with recent literature, confirmatory factor analyses (CFAs) favored a direct hierarchical model, where the g factor has a direct influence on WAIS-IV subtest performance and index scores explain only modest degrees of residual variance. Participants received the full WAIS-IV standard battery. We examined archival data from 300 concurrent psychological evaluations performed at a university-based community clinic. The current study expands the literature on the validity of WAIS-IV by testing a bifactor model in such a sample. Despite its popularity, construct validation studies primarily utilize the WAIS-IV normative sample rather than ecologically-valid clinical samples.
