Longitudinal Study of Low and High Achievers in Early Mathematics

BACKGROUND Longitudinal studies allow us to identify, which specific maths skills are weak in young children, and whether there is a continuing weakness in these areas throughout their school years. AIMS This 2-year study investigated whether certain socio-demographic variables affect early mathematical competency in children aged 5-7 years. SAMPLE A randomly selected sample of 127 students (64 female; 63 male) participated. At the start of the study, the students were approximately 5 years old (M= 5.2; SD= 0.28; range = 4.5-5.8). METHOD The students were assessed using the Early Numeracy Test and then allocated to a high (n= 26), middle (n= 76), or low (n= 25) achievers group. The same children were assessed again with the Early Numeracy Test at 6 and 7 years old, respectively. Eight socio-demographic characteristics were also evaluated: family model, education of the parent(s), job of the parent(s), number of family members, birth order, number of computers at home, frequency of teacher visits, and hours watching television. RESULTS Early Numeracy Test scores were more consistent for the high-achievers group than for the low-achievers group. Approximately 5.5% of low achievers obtained low scores throughout the study. A link between specific socio-demographic characteristics and early achievement in mathematics was only found for number of computers at home. CONCLUSIONS The level of mathematical ability among students aged 5-7 years remains relatively stable regardless of the initial level of achievement. However, early screening for mathematics learning disabilities could be useful in helping low-achieving students overcome learning obstacles.

Improving attention behaviour in primary and secondary school children with a Computer Assisted Instruction procedure

Attention disorders are one of the major sources of poor school performance. This research project was designed to examine whether a Computer Assisted Instruction (CAI) approach would be successful in achieving higher rates of attention. In order to increase attention behaviour during school time, psychologically‐designed software was developed. The software, called “How to improve your mental skills,” consists of three games based on multimedia perception tasks. First, 155 elementary school children with an average age of 12.4 years, from Cadiz (Spain) School District, were evaluated with two attention tests, the Perception Differences Test (PDT), and the subtest Spatial of Primary Mental Aptitude (S‐PMA). Students were divided and balanced into one experimental and two control groups, according to their scores on the PDT. Then, 10 training sessions, of 25 minutes each, with the software “How to improve your mental skills”, were administered to the experimental group. Children from control group 1 played...

Acquisition of Basic Concepts by Children with Intellectual Disabilities Using a Computer-Assisted Learning Approach

Computer-assisted learning can be an efficient learning-teaching procedure. Although there is an extensive educational software tradition for this approach, few have better performance than standard drill-and-practice methods. In this work, the specific software “Lets Play With …” was designed to teach concepts of colours, shapes, and body position to children with intellectual disabilities. The software structure follows the Gagné instructional design and applied behaviour analysis. The program was carried out with 39 boys and 21 girls who were special education students in the Cadiz School District. Statistically significant differences were found between groups taught with and without the software.

Stimulus Control with Computer Assisted Learning

Computer Assisted Learning (CAL) has been shown to be an efficient learning-teaching procedure. Although there is an extensive educational software tradition using CAL approaches, few of them have demonstrated a better student performance than standard drill and practice methods. The purpose of this study was (a) to evaluate the effectiveness of the “Lets Play With...” software program, and (b) to evaluate the effectiveness of a prompt (i.e. a blinking object) used in the program. The educational software “Lets Play With...” was designed to teach basic concepts involving shapes and body positions to preschool students. The software structure follows a behavioral design and uses a stimulus control procedure. The study was carried out with 64 preschool students in the Cadiz (Spain) School District. Statistically significant differences were found between the experimental group and a control group.
