Reported is another study related to the Project on an Information Memory Model. This study involved using information theory to investigate the concepts of primacy and recency as they were exhibited by ninth-grade science students while processing a biological sorting problem and an immediate, abstract recall task. Two hundred randomly selected…

This is a qualitative study of 22 9th graders performing generalizations on a task involving linear patterns. Our research questions were: What enables/hinders students' abilities to generalize a linear pattern? What strategies do successful students use to develop an explicit generalization? How do students make use of visual and numerical cues…

This research study deals with the modes of representation that ninth-graders choose in order to communicate their problem solving paths and justifications, and the relation between these modes of representations and achievement level. The findings are based on analysis of 350 answers to problems that demanded communication of reasoning,…

This paper presents the design and some results of a series of teaching experiments. The design was created to develop a model for everyday math lessons, that describes the conditions which foster or hinder the construction of new mathematical meanings. The development process includes the students' epistemic processes, their social interactions,…

The goal of this study was to find out if the difference between boys and girls in computer literacy can be leveled out in a laptop program where each student has his/her own mobile computer to work with at home and at school. Ninth grade students (n=113) from laptop and non-laptop classes in a German high school were tested for their computer…

Reliability methodology needs to evolve as validity has done into an argument supported by theory and empirical evidence. Nowhere is the inadequacy of current methods more visible than in classroom assessment. Reliability arguments would also permit additional methodologies for evidencing reliability in classrooms. It would liberalize methodology…

Most comparative studies about China were challenged by many sinologists and educators for not grounding on representative samples. This research is mainly based on a Chinese data base collected from a random sample of more than 10,000 9th-grade students in the Second International Association for the Evaluation of Educational Achievement (IEA)…

Adolescent suicide is the second leading cause of death in the adolescent population and is on the rise. This study used a mass screening concept as a pre-test identifier of at risk clients for suicide ideation and depressions; development of a competency-based prevention group treatment program, and the post-testing of the identified at-risk…

Loneliness is thought to be a relatively common experience among adolescents. Although no studies have specifically examined the relationship between adolescent loneliness and attributional style, research has found that children's attributions do affect interpersonal behaviors. The relationship between adolescent loneliness and perceptions of…

Junior high schools have been blamed for failing to meet the needs of early adolescents. Proponents of the new middle school structure favored moving grade nine to the high school and moving grade five and or six from the elementary school to the new structural organization. The uniqueness of the middle school is in how the philosophy behind this…

A study investigated two questions regarding the validity of holistic writing evaluation: (1) How well do holistic scores predict sentence length, passage length, and spelling errors in grades 3, 6, and 9 narrative and explanatory writing? and (2) Which model best predicts these variables (across grades within type, or within grade within type)?…

This study examined the effect on junior high school students of film-mediated, intensive instruction in either observing details or in generating hypotheses on basic problem solving skills; the study stemmed from teachers' indications that lack of sophistication in these areas has led to more structured activities. One hundred and twenty randomly…

The effects of instruction on the ability of children to generate written hypotheses and ask questions about variables pertaining to scientific discrepant events were investigated. Two hundred five ninth graders were assigned to a control group or one of four experimental instruction groups. The experimental instruction was received by watching a…

A widely held perception is that public schools are failing American children and society. Some research indicates that 9th-graders are more at risk for school failure than are students in other grades. This paper presents findings of a study that examined 9th-graders in the Durham Public School System (North Carolina) who were enrolled in a Basic…

This paper chronicles the evolution of a metaphorical graphical user interface (MGUI) at Lehigh University (Pennsylvania). From its inception, "The Funeral of Edgar" has been a guided exploration of Edgar Allan Poe's poem, "The Raven," aimed at modeling high school students' critical and analytical reading skills. This product…
