This paper presents an interactive multimedia program, "BioLogica", used to teach Grade 10 (14- and 15-year-olds) Australian students about genetics. Over six weeks, the teacher used different representations in the teaching and engaged students in computer…

This paper describes how a university outreach program promotes academic achievement and identity development among culturally diverse tenth-grade students. The primary goal of the outreach program is to advance students' engagement and competency in mathematics and science learning. A secondary goal of the program is to promote the development of…

The aims of this study were considered under three headings. The first was to elicit misconceptions that students had about the terms "solute", "solvent" and "solution." The second was to understand how students' prior learning affected their misconceptions. The third was to determine if students were able to make a…

This article describes the outcome of an exercise carried out with one hundred undergraduate student teachers (preservice teachers) enrolled in a Biology Teaching Methods course, a third year course in a four-year Teacher Education Programme. The students, working in groups of three to four, were assigned to construct a concept map showing their…

For the past few years the Florida School Code has set the Florida Comprehensive Assessment Test (FCAT) performance requirements for promotion of 3rd graders and graduation for 10th graders. Grade 3 students who do not score at level 2 or higher on the FCAT SSS Reading must be retained unless exempted for special circumstances. Grade 10 students…

This article reports an investigation into the factors that facilitate language learning. The first strand examines whether motivation is a predictor of as is widely accepted. In order to confirm this, Grade 10 students' motivation level was measured using two questions. Language gains were also measured and compared with the motivation level. The…

This unit is one of a series that presents specific moments in history from which students focus on the meanings of landmark events. The purpose of this unit is for the student to explore the advances in scientific knowledge made in Europe in the mid-sixteenth to mid-seventeenth centuries. These advances, beginning with Copernicus, radically…

This practicum was designed because out of school suspensions as a disciplinary procedure were not effective in changing students' behaviors. The students felt angry and rejected by the teachers, and they did not feel part of the school culture. The practicum offered a peace curriculum designed to be used in content academic areas, small groups,…

The study reported in this paper, combined qualitative (observation, interview and case study techniques) and quantitative (questionnaire and survey instruments) methods (n=3,182 Grade 10 students). The study (1) examined the relationship of current teaching practices to a number of variables that affected students' learning in science laboratory…

Four papers describe a study of the use of holistic writing assessment procedures in a pretest and posttest manner to determine improvement of 10th graders' writing skills. "Problem and Context" (James E. McLean) briefly describes the project and introduces the other three papers. "Holistic Scoring Procedures for Scoring Writing…

The purpose of the study was to compare two regression-based approaches for measuring educational effectiveness in Tennessee high schools: the mean residual approach (MR), and a more general linear models (LM) approach. Data were obtained from a sample of 1,011 students who were enrolled in 48 high schools, and who had taken the Comprehensive…

The authors describe one high school teacher's attempt to change her mathematics teaching in ways that are consistent with the National Council of Teachers of Mathematics'"Standards" documents. One of the coauthors is the teacher who teaches in a professional development school; the other, a researcher, conducted regular observations in…

This study was designed to gain a better understanding of interactive video instruction and its effects on individual learning in high school students in Taiwan. The study had three objectives: (1) to identify students' background information and involvement in computer assisted instruction; (2) to assess whether there is a linear relationship…

The Applied Biological and Agribusiness Interest Inventory was revised to reflect seven agricultural career clusters and to measure agricultural interest of eighth-grade students. A study conducted in Pennsylvania tested the interests of 8th-grade students and then developed scoring keys using 10th-grade students as the basis for the key. The…

This study examined the relative effectiveness of different types of computer feedback (both corrective and noncorrective) on student achievement. A total of 41 students in grades 9 and 10 comprised the two treatment groups. The subjects all interacted with a computer program written by the researcher. The first treatment group received corrective…
