An information system for dropout prevention

Reducing student dropout from school is one of the most important challenges faced by the education system. This study examines the effectiveness of a Local Authority Information Center (LAIC) that was developed in Israel to help prevent this phenomenon. The research population embraced 418 regular attendance officers (RAOs), educators dealing with students dropping out and with those who at risk of dropping out. The RAOs were divided into an experimental group, that executed its work using the LAIC, and a control group that accomplished its work manually. The research findings show that the use of an LAIC system reduced the dropout rate and raised the number of students studying to the school’s satisfaction. This improvement even intensified 3 years later when the size of the experimental group was increased. The RAOs in the experimental group employ most of the LAIC’s facilities and they present positive attitudes towards the LAIC’s contribution to their work. The LAIC system seems to have a real and direct impact on reducing dropping out.     

Gender differences in the severity of adult familial dyslexia

Thirty seven adults with a three generation family history of dyslexia and a strong personal history of reading/spelling problems were administered a psychoeducational battery to confirm the diagnosis of dyslexia. Males were not disproportionately represented in the dyslexic sample although they exhibited a more severe profile of reading impairment relative to females. Severity of dyslexia is discussed as a possible mechanism of the reported higher prevalence of dyslexia among males.     

Familial dyslexia: genetic and medical findings in eleven three-generation families

In addition to providing information on the inheritance of dyslexia, the present study of eleven three-generation families has provided a unique opportunity to compare affected and unaffected family members at all ages. The data presented here are based on pedigree information, a questionnaire administered to all participating family members in relation to sex ratio, handedness, the severity of dyslexia by sex, pre- and perinatal complications, medical complications, years of education and earning ability, and a battery of standardized tests to define the presence or absence of dyslexia. The pattern of inheritance was consistent with the postulated autosomal dominant mode of inheritance and penetrance was found to be > 90 percent. Of 73 individuals determined to have a gene leading to dyslexia, seven were classified as obligate carriers and six as compensated adults who had no current symptoms or diagnostic evidence of dyslexia. The sex ratio (1.06) was not different from the expected ratio of 1.04. Left-handedness, major pre- and perinatal complications, and autoimmune disorders and allergy were not more common in dyslexics than non-dyslexics. The number of years of education and average income were similar in affected and unaffected family members. Compensated adults and obligate carriers were similar to unaffected family members in each of these parameters.     

The seductive details effect in technology‐delivered instruction

Seductive details are highly interesting information tangential to course objectives. The inclusion of seductive details generally harms performance on recall tests, but few studies have used multimedia training or investigated effects on performance on recognition tests or transfer tasks. We conducted two studies using computer‐based training, instructing college students to use either Excel or Word mail merge. Contrary to most prior results, we found no negative effect for seductive details on recognition tests, and we found a facilitative effect on transfer performance. We discuss implications for theories of learning and transfer, and practical implications for instructional design and delivery.
