The use of a molecular viewer to visualize proteins has become more prevalent in high schools in recent years. We relied on the foundations of two theoretical frameworks to analyze questions in two learning tasks designed for 10th- to 12th-grade biotechnology majors that make use of Jmol. The two theoretical frameworks were: (i) classification of…

This study sought to determine if there was a relationship between teacher perceptions of educational change and student achievement. Teacher perceptions of change represented the independent variable and the dependent variable consisted of eleventh grade math Texas Assessment of Knowledge and Skills scores, cohort completion rates, and math…

Background/Context: From two decades of research on the grading practices of teachers in secondary schools, researchers discovered that teachers evaluated students on numerous factors that do not validly assess a student's achievement level in a specific content area. These consistent findings suggested that traditional grading practices evolved…

The purpose of this study is to examine the effects of a model-based introductory physics curriculum on conceptual learning in a Physics First (PF) Initiative. This is the first comparative study in physics education that applies the Rasch modeling approach to examine the effects of a model-based curriculum program combined with PF in the United…

This study compared modeling skills and knowledge structures of four groups as seen in their understanding of air quality. The four groups were: experts (atmospheric scientists), intermediates (upper-level graduate students in a different field), advanced novices (talented 11th and 12th graders), and novices (10th graders). It was found that when…

This study tested a new model of the occupational decision-making processes of senior high-school students, which incorporates cultural and motivational perspectives. A theoretical framework guided the study. A refined version of a previously used survey instrument was administered to 566 Australian Grade 11 students attending a stratified random…

The purpose of this study is to examine the differences in achievement on the end of course assessment in Geometry and the Grade 11 Literacy exam administered to students in Arkansas during the 2005-2006 and 2006-2007 school years. The three main types of scheduling are the traditional schedule with seven or eight periods; the A/B, or the…

This paper describes a disruptive model of interpretation which explores positions in discursive practices embedded in visual culture as a means of understanding self and difference. The model understands interpretation as a Foucauldian technique of the self, and its use may give art teachers and students strategies for understanding the social…

In the last few years educational researchers have become increasingly aware of the need to examine interaction among students to understand the impact of cooperative small groups on learning. For this study 26 students in an 11th-grade Algebra II/Trigonometry class were trained to use a didactic cooperative learning technique called scripted…

A nationwide survey of over 3,000 grade 11 students (approximately equal numbers of males and females) representing major urban areas in all ten provinces was undertaken to obtain baseline data on access to and usage of computers in each of three categories--recreational, nonrecreational home usage, and school--and to test a "manifold…

Research in science and mathematics education has indicated that students often use inappropriate models for solving problems because they tend to mentally represent a problem according to surface features instead of referring to scientific concepts and features. The objective of the study reported in this paper was to determine whether 34 Israeli…

A five-step method of conflict analysis can help students generate accurate and complex theme statements about literature without teacher intervention. The conflict analysis involves (1) identifying the characters who are in conflict as a series of pairs and determining if the protagonist has an inner conflict; (2) determining the major conflict,…

A study assessed the ability of 20 eleventh grade students to recognize particular stylistic features when reading and then to use such features in their writing. Half the subjects were given a model paragraph from an Edgar Allen Poe story, without having the story identified for them, while the other half received only a verbal summary of the…

In grade 11, students use the life and work of Cesar E. Chavez as a case study to trace the major historical eras and events of the 20th century. Students start by studying the Chavez family at the beginning of the 20th century, learning about them as they struggled to acquire a farm in Arizona and raise a family. They also learn how they faced…

A project involving thirty-nine eleventh grade students was undertaken at a senior high school to plan and initiate a community-based action learning program to provide students with a meaningful cooperative school-community work learning experience. Specific curriculum requirements were met through a combination of independent study,…
