This study aimed to capture the development of interaction among the components of pre-service chemistry teachers' enacted PCK throughout the school experience course. Data were collected from four pre-service teachers using content representation (CoRe), observations, field notes, and semi-structured interviews. Secondary analysis was conducted…

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…

When different disciplines that physics lesson is related are examined, it is seen that mathematics becomes prominent as one of the most used fields. Physics textbooks are the most significant resources to clarify this relationship. Therefore, in this study, it is aimed to analyze the involvement of mathematical knowledge in physics textbooks used…

In this study, the authors conducted a mixed analysis of student perceptions of their best high school teachers. The sample of 257 preservice teachers from a College of Education in California described their best high school teacher. From their descriptions, qualitative analysis through the method of constant comparison yielded eight themes:…

This study examined the problem-solving protocols of 21 students in a grade 11 enriched physics course as well as 3 adult "experts" in physics. Experts and high performing students made more correct metastatements and more references to prior knowledge than did average performing students. (DB)

The purpose of this study was to assess the impact of eighteen 11th grade high school chemistry students' prior mathematical knowledge on their understanding of certain chemical concepts (symbol, formula, and equation). It also investigated students' ideas about the meaning of plus sign, reaction sign, and the relationships between subscript, and…

The national survey reported in this document focused on 11th grade students' knowledge of literature and U.S. history. While approximately two-thirds of the history questions were answered correctly, performance on the literature assessment was slightly lower, perhaps because some questions were asked about authors and literary works not included…

This study determined that there is a positive and significant relationship between the quality of supervised occupational experience, as measured by labor income and the scope of the student's program, and the level of achievement in technical knowledge for students in production agriculture.

The degree of gender differences in mathematics and science appears to vary with the content subdomain. Differences also appear to be greater on items assessing content knowledge than with items measuring reasoning about scientific processes. Many studies of gender differences have involved fairly select populations. This study focuses instead on…

During 1990, the National Assessment of Educational Progress (NAEP) reported findings about elementary and secondary school students' knowledge of U.S. history, geography, and civics. In 1988, the Joint Council on Economic Education reported findings from its national study of high school students' knowledge of economics. The designers and…

This study investigated how domain specifications controlled topic and rater reliability. History students completed three performance tasks. For each topic, they took prior knowledge tests, read primary materials, and wrote explanatory essays. Using a theory-based scoring rubric, four raters scored all essays. The rubric worked similarly on the…

The assumption that learners are the best judges of learning needs in computer-assisted instruction was tested by assigning 55 eleventh graders to learner-control or program-control conditions. Results indicate that efficiency of the learner-control strategy cannot be taken for granted and emphasize the importance of prior knowledge. (SLD)

This research applied evolving conceptions of learning to examine how to represent and evaluate students' and experts' cognitive structures. High school history students completed several tasks. Direct comparisons of the quality of student maps with expert maps showed that experts' concept maps could be used to score students' concept maps…

The impact of the Channel One school newscasts on student knowledge of current events and on student attitudes was studied with tenth and eleventh graders in six suburban high schools in the Midwest. Three schools (464 students) received the newscast and the remaining schools (604 subjects) did not. Current events knowledge was assessed with a…

As part of a project on assessing deep understanding of subject matter, a study was conducted to assess students' knowledge of history by focusing on essay writing. Reading a provided text was incorporated into the assessment procedure. Ratings from five high school history teachers were compared with those of four English teachers for 85 essays…
