Current research and learning theory suggest that a hierarchy of proportional reasoning exists that can be tested. Using G. Vergnaud's four complexity variables (structure, content, numerical characteristics, and presentation) and T. E. Kieren's model of rational number knowledge building, an epistemic model of proportional reasoning was…

A collection of articles on dictionaries for advanced second language learners includes essays on the past, present, and future of learners' dictionaries; alternative dictionaries; dictionary construction; and dictionaries and their users. Titles include: "Idle Thoughts of an Idle Fellow; or Vaticinations on the Learners' Dictionary"…

A study was conducted to measure faculty perceptions of academic standards and the level of academic intensity in transfer courses. Questionnaires were sent to chief academic officers (CAO's) at 30 community colleges, asking them to distribute five instruments to members of the academic senate and five to instructors who were not members of the…

The psychological mechanisms that underlie human question asking and answering during comprehension and complex learning were studied. The transcripts of 83 tutoring sessions on research methods for college students and 22 algebra tutoring sessions for seventh graders were collected and analyzed. It was estimated that student questions were about…

This yearbook is the seventh for the Mathematics Education Research in Finland series and contains ten articles presented at the decennial jubilee colloquium. The first three articles discuss Constructivism both in general and with regard to mathematics education. Analysis is directed to the origins of constructivism, to the learning of…

External representations have a great impact on what and how students learn. One key manner in which environments can operate upon novices' knowledge is through helping them ground their problem solving in an understanding of the situation embodied by the problem. In this paper, students' difficulties in microeconomics problem solving were…

The hardware and software system used to create the National Opinion Research Center/Center for Research on Evaluation, Standards, and Student Testing (NORC/CRESST) item databases and test booklets for the 12th-grade science assessment are described. A general description of the capabilities of the system is given, with some specific information…

Arranged into two major parts, the guide offers practical and motivating techniques for teaching secondary art. The first section, a brief curriculum guide, presents a rationale, program goals, learning outcomes, program scope and sequence, course list, and evaluation information. The largest part of the document is a resource guide providing…

A study investigated whether instruction in how to use a dictionary led to improved second language performance and greater dictionary use among English majors (N=54) in a reading and writing course at a Thai university. One of three participating classes was instructed in the use of a monolingual learner's dictionary. A passage correction test…

A study investigated patterns in the apparent syntactic errors of native English-speaking, upper-level learners of Arabic as a foreign language. One hundred writing samples, including summaries, criticisms, and free composition, were gathered from a number of university courses. Error types analyzed included articles, subordinate clauses, two-word…

This study investigated the sensitivity of the pupillary response as an indicator of average mental load during three language processing tasks of varying complexity. The tasks included: (1) listening (without any subsequent comprehension testing); (2) speech shadowing (repeating a message in the same language while listening to it); and (3)…

Advanced learners of second languages and natural language processing systems both demand much more detailed lexical information than conventional dictionaries provide. Text composition, whether by humans or machines, requires a thorough understanding of relationships between words, such as selectional restrictions, case patterns, factives, and…

The Cattell Culture Fair Intelligence Test (CCFIT) was administered to a large sample of American, Nigerian, and Indian adolescents, and item data were examined for cultural bias. The CCFIT was designed to measure fluid intelligence, which is not influenced by cultural differences. Four different item analysis techniques were used to determine…

This study investigated the effects of medium of instruction, task difficulty, and gender on continuing motivation. A total of 139 fifth and sixth graders with previous computer experience completed an initial learning task in one of the two media formats (computer or paper/pencil) and under either a hard or easy difficulty level. Students' choice…

This study examined the need to develop reliable and valid procedures for screening large populations for possible speech and language problems and the use of the Fluharty Preschool Speech and Language Screening Test (FPSLST) as such a device. The test was administered to 260 preschool children, ages three to six. There were 166 Blacks and 94…
