In this study, it was aimed to develop an achievement test taking into account the subject acquisitions of the sound and properties unit in the sixth-grade science course. In the test development phase, firstly, literature review for the study was conducted. Then, 30 multiple choice questions in align with the subject acquisition in the 2018…

This study presents the development and validation of a novel multiple-choice test designed to assess university students' conceptual understanding of electric field, force, and flux. The test of understanding of electric field, force, and flux was constructed based on the results of previous studies using a phenomenographic approach to classify…

Research-based multiple-choice questions implemented in class with peer instruction have been shown to be an effective tool for improving students' engagement and learning outcomes. Moreover, multiple-choice questions that are carefully sequenced to build on each other can be particularly helpful for students to develop a systematic understanding…

The scope this article was to develop an instrument to measure Chemistry students' ability regarding 'physical bonding' and to validate it. A number of 24 items were developed by mapping items to cognitive levels described by the Marzano taxonomy. A number of N=73 students were evaluated. Four items exhibited a MNSQ >1.3 and were eliminated…

We introduce a template to (i) scaffold the problem solving process for students in the physics 1 course, and (ii) serve as a generic rubric for measuring how expertlike students are in their problem solving. This template is based on empirical studies of the problem solving practices of expert scientists and engineers, unlike most existing…

Momentum is a foundational concept in physics. Although it is often taught in introductory mechanics courses, there are a limited number of studies on this topic in the literature. The results from these studies have consistently shown that students have difficulties in understanding momentum, especially the connections between net force, time,…

Foundational undergraduate courses in chemistry and mathematics are gateways to a number of lucrative majors and pre-professional programs. Historically, however, students often struggle with these disciplines and can benefit from alternate approaches to examining their learning strategies. This article describes the use of exam…

College instructors in the United States usually make their own decisions about how to design course exams. Even though summative course exams are well known to be important to student success, we know little about the decision making of instructors when designing course exams. To probe how instructors design exams for introductory biology, we…

The understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item…

The aim of this research was to explore students' ideas about chemical reactions and difficulties in understanding the law of conservation of mass in such reactions by using an approach that started from presentations of scientists' work associated with the law. The developed test items relied on: 1) the historical contents that illustrate the…

The study investigated the use of Quantum Physics Conceptual Survey (QPCS) in probing student understanding of quantum physics. Altogether 103 Finnish university students responded to QPCS. The mean scores of the student responses were calculated and the test was evaluated using common five indices: Item difficulty index, Item discrimination…

We present the Electricity and Magnetism Conceptual Assessment (EMCA), a new assessment aligned with second-semester introductory physics courses. Topics covered include electrostatics, electric fields, circuits, magnetism, and induction. We have two motives for writing a new assessment. First, we find other assessments such as the Brief…

Chemical stoichiometry is a conceptual framework that encompasses other concepts such as the mole, writing of chemical equations in word and representative form, balancing of equations and the equilibrium concept. The underlying concepts enable students to understand relationships among entities of matter and required amounts for use when…

Students' ability to effectively study for an exam, or to manage their time during an exam, is related to their metacognitive capacity. Prior research has demonstrated the effective use of metacognitive strategies during learning and retrieval is related to content expertise. Students also make judgments of their own learning and of problem…

It is suggested that most standardized science tests do not adequately assess the majority of concepts taught as part of the very diversified middle school science curriculum. The 50-item Life Science Test constructed by Portland Public Schools, Maine, herein presented, aims to resolve this inadequacy. The 40-minute multiple choice test…
