The purpose of the study was to assess elementary students' science process skills, content knowledge, and concept knowledge after one year of participation in an elementary Science, Technology, Engineering, and Mathematics (STEM) program. This study documented the effects of the combination of intensive professional development and the use of…

Gene expression is a highly theoretical concept that requires advanced reasoning skills to comprehend. Often, students receive instruction but fail to replace prior conceptions and thus do not benefit. In order to investigate the reason for this failure, we used a directed inquiry activity that uses concrete analogies in both majors and non-majors…

This study was the result of classroom action-based research class in a mainstreamed class of 26; 6 students were special ed and 2 students were English Language Learners. Because it was a split grade, I had double the amount of science topics from which to choose. This study examined quality experiments for junior students and optimal strategies…

The educational video game Mission Biotech provides a virtual experience for students in learning biotechnology materials and tools. This study explores the use of Mission Biotech and the associated curriculum by three high school teachers and their students. All three classes demonstrated gains on a curriculum-aligned test of science content.…

Both multiple-choice and constructed-response items have known advantages and disadvantages in measuring scientific inquiry. In this article we explore the function of explanation multiple-choice (EMC) items and examine how EMC items differ from traditional multiple-choice and constructed-response items in measuring scientific reasoning. A group…

The "Standards for Educational and Psychological Testing" indicate that test instructions, and by extension item objectives, presented to examinees should be sufficiently clear and detailed to help ensure that they respond as developers intend them to respond (Standard 3.20; AERA, APA, & NCME, 1999). The present study investigates…

Many United States secondary students perform poorly on standardized summative science assessments. Situated Assessments using Virtual Environments (SAVE) Science is an innovative assessment project that seeks to capture students' science knowledge and understanding by contextualizing problems in a game-based virtual environment called…

A hands-on, minds-on inquiry chemistry experiment was developed for use in K-12 schools that enables students to combine the chemicals of their choice and observe the results. The chemistry involved is water based and builds upon acid-base, double displacement, and iodometric detection of starch reactions. Chemicals readily available in the…

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life-science module. The assessment we developed…

Due to the poor performance of US students in international math and science tests, many authors worry that the US lead in science is in jeopardy. A recent study by Chen and Luoh ("Soc Indic Res" 96: 133-143, 2010) challenged this pessimistic view by delinking test performance and labor force quality. It was found that measures such as…

Our aim was to deepen understanding of public examinations, exploring how marking task demands influence examiners' cognition and ultimately their marking accuracy. To do this, we identified features of examinations that trigger or demand the use of cognitive marking strategies entailing "reflective" judgements. Kelly's Repertory Grid…

In this study we examine the interplay between curriculum-embedded formative assessment--a well-known teaching practice--and general features of classroom process quality (i.e., cognitive activation, supportive climate, classroom management) and their combined effect on elementary school students' understanding of the scientific concepts of…

Although researchers call for inquiry learning in science, science assessments rarely capture the impact of inquiry instruction. This paper reports on the development and validation of assessments designed to measure middle-school students' progress in gaining integrated understanding of energy while studying an inquiry-oriented curriculum. The…

Stanford education professor Martin Carnoy examines four main critiques of how international test results are used in policymaking. Of particular interest are critiques of the policy analyses published by the Program for International Student Assessment (PISA). Using average PISA scores as a comparative measure of student achievement is misleading…

The Cultural Heritage Bilingual Program (CHBP) was developed for English Language Learner (ELL) students from language groups not served by current bilingual programs in the Houston Independent School District (HISD). The two main bilingual programs in the district (Transitional Bilingual and Dual Language Bilingual) are designed to serve ELLs…
