This report focuses on the initial development of the predicted score paths for ACT Aspire reporting. The paths provide predicted score ranges for the next two years--as well as predicted ACT score ranges for tests administered at grades 9 and 10. Longitudinal ACT Aspire data for students tested in spring 2013 and spring 2014, as well as…

The purpose of this study was to investigate the impact of a 2-year professional development model in math and science on the self-efficacy of the teacher and its effects on teacher practice and student outcomes. Further, this study sought to incorporate the instructional use of Inquiry-Based Learning methods of Problem-Based Learning, Japanese…

This research aims to investigate the influence of conceptual change texts on students' understanding and misconceptions related to the subject of alkenes. For this, nine conceptual change texts were developed by considering students' misconceptions and learning difficulties regarding alkenes. The participants of this study consist of 63 second…

The problem-solving strategies of students enrolled in general chemistry courses have been the subject of numerous research investigations. In most cases, the investigators were interested in the specific areas or concepts that posed the greatest difficulty to a student's success in achieving the correct answer. However, the investigation reported…

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…

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…
