This study aims to demonstrate the optimal way to determine the cut-off score to be used to interpret the total scores obtained from an achievement test or scale using the Artificial Neural Networks method. To this end, the multiple-choice item responses in the Booklet-11 Mathematics subtest at the 8th grade level in the TIMSS 2015 Turkey sample…

The aim of this study is to determine the effect of variables such as gender, class and parental education level, family income level on motivation levels of students to learn science and do research, performance, communication, collaborative work and participation. The study group of the study was in the 2015-2016 academic year, public schools in…

IEA's International Computer and Information Literacy Study (ICILS) 2018 investigated how well students are prepared for study, work, and life in a digital world. ICILS 2018 measured international differences in students' computer and information literacy (CIL): their ability to use computers to investigate, create, participate, and communicate at…

This article presents a cohesive, empirically grounded categorization system differentiating the types of generalizations students constructed when reasoning mathematically. The generalization taxonomy developed out of an empirical study conducted during a 3-week teaching experiment and a series of individual interviews. Qualitative analysis of…

Two studies examine the stability of existing friendships and the formation of new friendships during a school year, for children in Grades 1, 4, and 8. Most friendships present in the fall of the school year remained constant in the spring. The formation of new friendships varied consistently with age. (Author/NH)

Using data from the National Education Longitudinal Study of 1988 (NELS:88), the authors investigate whether four groups of Asian Americans (Chinese, Korean, Filipino, and South East Asian) show comparable scores on variables that past studies have found to be related to academic achievement and whether these variables similarly predict academic…

Attitudes toward mathematics and attitudes toward computers were examined for 1,018 grade 8 students and 800 grade 12 students. The female students were more likely than the male students to associate negative attitudes toward mathematics with negative attitudes toward computers. Participation in an eighth-grade mathematics course with a computer…

Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

The authors test biosocial models that posit interactions between biological variables (testosterone, estradiol, pubertal status, and pubertal timing) and social context variables (family, peer, school, and neighborhood) in predicting adolescent involvement with cigarettes and alcohol in a sample of 409 adolescents in Grades 6 and 8. Models…

This study investigated the effects of sequence and synthesis prescriptions from the Elaboration Theory by teaching the parts of a microcomputer system based on a parts-conceptual structure. A 2x3 factorial design was used which incorporated two sequences, general-to-detailed and detailed-to-general, and three levels of synthesizer, i.e., no…

Determined how 430 eighth-grade students perceived science teaching as a career. One area investigated was the relationship between student ratings of science teaching as a career and such variables as sex, race, age, educational aspirations, and mother's/father's education and job type. (JN)

Four types of computational estimation were explored in relation to other mathematical skills and sex differences with 309 eighth graders. Open-ended estimation was the most difficult, followed by estimation relative to a reference number and estimation within an order of magnitude. (MNS)

Divided into poor readers and good readers, 144 Swedish students (13-14 years old) participated in an experiment in which oral reading speed, free recall, and summarization of narrative stories presented on videotex were studied as a function of reading skill, text structure, and physical factors. Good readers outperformed poor readers. (BRR)

Since the Internet was introduced in the field of Educational Technology, it has predominantly been seen as an instructional tool. A number of educational technologists point out that the Internet can be a powerful instructional tool that encourages learners to be involved in problem-solving by using a great deal of information and to enlarge and…

This study investigated the perception of emotions and the social skills of 60 eighth-graders, half with and half without learning disabilities (LD). Results indicated that the performance of LD adolescents was significantly poorer than peers in the perception of emotion via either auditory, visual, or combined auditory-visual modes. Although both…
