This case study contrasts the strategies used by two students in solving bilateral symmetry and reflection tasks, based on the differential properties they attended to. The ninth grader focussed on congruence of sides as the main property of reflection whereas the eighth grader focussed on perpendicularity and equi-distance, as is the normative…

This study investigated potential gender differences in a sample of 807 Year 6 Singaporean students in relation to two variables: spatial visualisation ability and cognitive style. In contrast to the general trend, overall there were no significant gender differences on spatial visualisation ability. However, gender differences were prevalent…

Exponential functions are important topic in school algebra and in higher mathematics, but research on students' thinking suggests that understanding exponential growth remains an instructional challenge. This paper reports the results of a small-scale teaching experiment with students who explored exponential functions in the context of two…

The purpose of this paper is to determine whether the changes that were found to occur pre- to post intervention in students' cognitive structures (Mills, 2013; Knezek, Christensen, Tyler-Wood, & Periathiruvadi, 2013) continued to persist two years later. Major findings were: a) semantic perception of science and STEM as a career became more…

The primary purpose of this study was to evaluate the application of a process approach for the teaching of algebra with a heterogeneous class of eighth-grade students. The assessment was conducted by identifying the processes used by above-average, average, and below-average algebra students in solving standard and nonstandard problems ranging…

Piaget's theory that distinct stages in the organization of memory correspond to successive stages in cognitive development was tested using 150 eighth graders. Cognitive levels were assessed with Inhelder and Piaget's balance beam task, initially, and again at seven months. Mnemonic levels were assessed with Piaget and Inhelder's memory of an…

A study designed to investigate the association between Piagetian cognitive and long-term mnemonic (recall and recognition) levels and problem solving in mathematics was conducted with 152 eighth-grade students. Cognitive level was determined by two evaluations (seven months apart) of a subject's performance on a clinically administered balance…

A study examined whether students were able to transfer the learning of a modeled "think-aloud" strategy to comprehension monitoring in other learning situations. Sixty-four eighth grade students in a midwestern town were identified as average proficiency readers based on a cloze test. There were no significant differences among the…

A think-aloud protocol study examined changes in real-time cognitive, metacognitive, and motivation processing that may have resulted from reading-strategy training. Eighth-grade students participated in 4 weeks of reading-strategy training during social studies class. Students used their own social studies text during the training. Fourteen…

A study examined the relative merits of characteristics of general modeling when applied to cognitive modeling of reading comprehension processes and whether the characteristics of modeling, when applied to cognitive modeling of reading processes, influence comprehension and comprehension monitoring. Subjects, 100 eighth grade students who could…

A study examined whether (1) the performance of students on text explicit (TE), text implicit (TI), and script implicit (SI) questions inserted in a text would vary as a function of the type of question received; (2) students responding in writing to the inserted questions would perform at a higher level on a subsequent criterion test than those…

This study examined the effects of episodic-mapping, traditional notetaking, and rereading on eighth-grade students' recall of historical text. Episodic-maps are a kind of notetaking procedure that requires students to represent ideas from a text in the form of a graphic diagram. As predicted, both episodic-mapping and traditional notetaking…

The observation of 18 hours of videotapes of 44 eighth grade boys and girls working in same-sex and mixed-pair groups with MYRESNAK (A Danish variation of LOGO) mathematics software indicated gender-specific differences in cooperation and work style. These differences are explained in terms of gender-specific socialization practices and are…

The development and use of item shells in the construction of a series of standardized tests of reading comprehension at the elementary school level are described. An item shell is an item that is devoid of specific content, but contains key words and a distinctive syntactic structure. The specific content of the item shell varies depending on the…

Examines the effects of a 10-week program designed to heighten fifth- and eighth-grade students' awareness of information explicitly stated in text, implied by text, and found only in the individual's knowledge base. (FL)
