Despite the importance of evolution to understand biology, there is significant evidence that many biology teachers have difficulties to successfully teach this topic. The purpose of this study is to describe procedures by which a paper-and-pencil instrument to assess teachers' pedagogical content knowledge for evolution (PCK[subscript evo]) was…

International large-scale assessments of student achievement such as International Association for the Evaluation of Educational Achievement's Trends in International Mathematics and Science Study (TIMSS) and Progress in International Reading Literacy Study and Organization for Economic Cooperation and Development's Program for International…

It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

Passive, lecture-based forms of instruction are often ineffective in helping students develop deep conceptual understanding of scientific concepts. Student-centered forms of instruction based in a constructivist framework, where students are guided toward actively constructing their understanding, have been met with greater success. However,…

This tutorial addresses possible sources of confusion in interpreting trait scores from the bifactor model. The bifactor model may be used when subscores are desired, either for formative feedback on an achievement test or for theoretically different constructs on a psychological test. The bifactor model is often chosen because it requires fewer…

Summarizes results of a questionnaire asking if the ASC standarized test influences what is taught in inorganic chemistry courses. Chief controlling factors are indicated to be: (1) instructor's preference and (2) textbook content. Suggestions are given to enhance amount of inorganic chemistry in undergraduate curricula.

With the administration of the 2002 Delaware Student Testing Program (DSTP), a questionnaire was given to students in grades 3, 5, 8, and 10 about Opportunity to Learn, Reading, Writing, and Mathematics, and to all students in grades 4, 6, 8, and 11 about Opportunity to Learn, Science, and Social Studies. Students responses to the questions were…

Describes how one instructor developed a biology questionnaire designed to get students interacting and thinking about biology course content on the first day of class. Discusses why student interest is captured, how the questions are made, and how the questionnaire results are used in class. Contains a 15-question true/false questionnaire. (LZ)

Twelve articles present excerpts from several national reports of countries participating on the Second International Science Study (SISS) of the International Association for the Evaluation of Educational Achievement. The SISS examined science achievement and its correlates in participating countries and studied trends from 1970 through the…

The Teacher Assessment Scheme (TAS) is a form of school-based assessment that has recently replaced the external practical examination in AL Biology of Hong Kong. This study aimed at understanding the problems encountered by teachers in implementing this innovation. Over 300 teachers expressed their concern about different aspects of the TAS in a…
