This study explores the extent to which the term "sex hormone" is used in science textbooks, and whether the use of the term "sex hormone" is associated with pre-empirical concepts of sex dualism, in particular the misconceptions that these so-called "sex hormones" are sex specific and restricted to sex-related physiological functioning. We found…

Finds that high school physical science students prefer textbooks with expository text that not only gives a correct concept but refutes common incorrect ideas. Finds that writing a comprehensible text is more difficult than the researchers had imagined. (SR)

Defines textbook genre as the manner of presentation of material and implied relationship between the author and reader. Describes a method of objectively dividing textbooks into moves separated by shifts in emphasis, and gives a genre analysis of an exemplar textbook to demonstrate how the technique might be useful in evaluating textbooks for…

Textbooks for GCE Advanced Level Biology have provided over-simplified and inaccurate accounts of Charles Darwin's contribution to the study of evolution over a period of many decades. They have credited him with field skills and insight that he did not possess, and repeated several historical inaccuracies. Darwin's strength was as a synthesiser…

Three high school biology textbooks were analyzed to determine possible sources of misconceptions and related learning problems associated with genetics. Misconceptions were examined in these categories: conceptual organization; conceptual relations; use of terminology; and mathematical elements. Implications for instruction related to each…

A study examined text-based scientific concepts and described how those concepts were elaborated in three high school biology textbooks. The three textbooks were aimed at different student audiences: non-college bound students, special education students, and high school students at all levels. A concept analysis was established for each text, and…

Analyzed the commonly used science textbooks (n=8) to determine their cognitive level of questions. Among the conclusions are that there was a greater proportion of lower-level questions than higher-level questions in these books. (PR)

This article analyzes how science classes carry ideological elements and how that has ethical and deontological consequences with respect to science teaching. Provided are some examples of ideologizing, presenting a worldview, biased contents, and biased image of science. (YP)

Reports on an investigation of 31 introductory geology textbooks indicating that the concept of contact between bodies of rock is only rarely discussed. Data collected pertaining to 15 related terms demonstrated that many are either omitted or inadequately covered. (TW)

Questions the continued misuse of Markovnikov's Rule in organic chemistry texts. Claims that the results of several studies that show the reaction to be more complex than it appears at first. Criticizes authors of new texts who have perpetrated the rule based on reading older texts. (TW)

Reports on a content analysis of 14 textbooks on endocrinology. Using thyrotoxicosis as the content maker, the study indicated major differences between books with regard to the information provided and the number of words devoted to the subject. Suggests that medical teachers selecting textbooks be aware of such differences. (TW)

A comparative study of textbook terms was conducted to determine what high school science skills are necessary for success in associate degree physical science courses. Results indicate that, although enrollment in technology-training programs is increasing, high school textbook treatment of terms remains inadequate preparation for junior college…

Linguistic content analysis, method of encoding textual data by categorizing key words and identifying relationships, was developed to assess degree to which science was portrayed as process of inquiry within high school biology textbook series. The frequency of science as a process of inquiry increased from 1956 to 1965, then showed a pattern of…

A study examined the general content and characteristics of elementary science textbooks and compared selected text segments from several content domains across publishers. The Merrill and Silver-Burdette science programs for grades 1-5 and one level of both the Holt and McGraw-Hill programs were evaluated. Results indicated substantial…

Classroom teachers frequently express concern that textbooks and other curriculum materials are too difficult for their students. The objectives of this investigation were to develop a method for scoring the Level of Abstraction (LOA) of science reading material, and explore its relationship with certain other known methods for assessing…
