Phylogenetic trees are important tools for teaching and understanding evolution, yet students struggle to read and interpret them correctly. In this study, we extend a study conducted by Catley and Novick (2008) by investigating depictions of evolutionary trees in US textbooks. We investigated 1197 diagrams from 11 German and 11 United States…

Reading texts may serve as a vital source of informational content and language knowledge for second language (L2) learners, which is known as the dual relevance of L2 reading (Han & D'Angelo, 2009). Text complexity, however, influences the two, determining to a great extent whether the dual outcome is attainable. Drawing on Complex Dynamic…

In today's university era, reforming the English teaching model has become a major research topic for researchers. Based on this, this paper adopts a hierarchical and progressive model construction method to further explore the reform model of university English teaching in the context of educational ecology. First, this paper discusses the…

A corpus of current editions of statistics textbooks was assessed to compare aspects and levels of readability for the topics of "measures of center," "line of fit," "regression analysis," and "regression inference." Analysis with lexical software of these text selections revealed that the large corpus can…

Following the trend in science and engineering education generated by the visible impact created by the Force Concept Inventory (FCI), the investigator developed a Physics of Semiconductors Concept Inventory (PSCI). PSCI fills the need of standardized concept tests for undergraduate education in photonics and electrical engineering. The structure…

The 13th iteration of the International Conference on Educational Data Mining (EDM 2020) was originally arranged to take place in Ifrane, Morocco. Due to the SARS-CoV-2 (coronavirus) epidemic, EDM 2020, as well as most other academic conferences in 2020, had to be changed to a purely online format. To facilitate efficient transmission of…

These proceedings contain the papers of the 14th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2017), 18-20 October 2017, which has been organized by the International Association for Development of the Information Society (IADIS) and endorsed by the Japanese Society for Information and Systems in…

Compares statistical techniques used in American Educational Research Journal (AERJ) articles with techniques described in graduate-level textbooks. Reports that most AERJ articles are comprehensible to students with at least an intermediate-level knowledge of statistics. Also compares types of AERJ techniques with those used in the Journal of…

Analyzes multiple-choice questions provided in test banks for introductory psychology textbooks. Study 1 offered a consistent picture of the objective difficulty of multiple-choice tests for introductory psychology students, while both studies 1 and 2 indicated that test items taken from commercial test banks have poor psychometric properties.…

The readability, interest level, and content of 18 current college textbooks on mainstreaming were assessed. Results revealed that readability and interest level were comparable among the texts. More variation was found in the contents of the texts. A table lists 16 topics and the degree to which each is covered in the textbooks. (DB)

The accuracy of 210 college undergraduates' judgments of the relative learnability of original (Army training manuals) and rewritten (war or cultural histories) versions of 20 pairs of texts of known difficulty was studied. Students were 95 percent accurate in their judgments of learnability. Implications for college textbook selection are…

The learning difficulties described by students in statistics courses continue to engage researchers from several disciplines. One source of difficulty for graduate students in educational statistics courses is the reading difficulty of the textbook. Instructors making decisions about a textbook typically have little information about the reading…

Parts 1 and 2 (SE 524 424 and 527 089) described Flesch readability for determining a text's reading level and results of applying the test to astronomy/physics textbooks. This part presents results for a new sample of texts, including calculus-level texts. A comparison with high school physics texts is provided. (JM)

Diagrams are considered to be invaluable teaching and learning tools in biochemistry, because they help learners build mental models of phenomena, which allows for comprehension and integration of scientific concepts. Sometimes, however, students experience difficulties with the interpretation of diagrams, which may have a negative effect on their…

A study of reading textbooks for English as a second language published in Japan evaluated 150 traditional reading textbooks and 32 new reading textbooks published for use in 1985. Traditional reading textbooks are those with main texts and notes and sometimes a few comprehension questions. New reading textbooks have main texts, comprehension…
