Learning progressions (LPs) are novel models for the development of assessments in science education, that often use a scale to categorize students' levels of reasoning. Pictorial representations are important in chemistry teaching and learning, and also in LPs, but the differences between pictorial and verbal items in chemistry LPs is unclear. In…

The aim of this research is to study the merits and complementarity of Construct Mapping and Categorical Principal Components Analysis as two approaches that explore the dimensionality of multiple-choice items in achievement tests. Data from the two forms of the Romanian National Assessment Tests on Science were used to explore the dimensionality…

Multiple-choice testing is a staple within the U.S. higher education system. From classroom assessments to standardized entrance exams such as the GRE, GMAT, or LSAT, test developers utilize a variety of validated and heuristic driven item-writing guidelines. One such guideline that has been given recent attention is to randomize the position of…

This study was conducted to examine the achievements of students in the concepts of light and shadow measured in different assessment formats according to the learning style and gender. In this study, correlational survey model was used. The sample consisted of 10th grade (16 years) high school students (n=815) from different types of six high…

The development of knowledge assessment instrument based on problem solving in the electrochemistry. This research aimed to find out the characteristics, teacher responses, and student responses to the problem-based knowledge assessment instrument on the electrochemistry material. The research method used is research and development which consists…

Background: We adopted a theoretical framework that the acquisition of a scientific concept comprises the development of connections among conceptual elements associated with a scientific term within a mental semantic network. Given this framework, the hypothesis that the surrounding words connected with a scientific term are relevant to the…

In this article, we discuss the development and the administration of a multiple-choice test, which we named "Test of Calculus and Vectors in Mathematics and Physics" (TCV-MP), aimed at comparing students' ability to answer questions on derivatives, integrals, and vectors in a purely mathematical context and in the context of physics.…

Learners need to possess scientific literacy in order to be able to analyze and explain scientific concepts and solve daily life problems. The current study aimed to analyze the potential of the Socio-Science Spirituality learning model to improve the scientific literacy of students at the junior high school level. The sample of this research…

Student learning in simple electric circuits has been extensively studied, which has revealed a large number of persistent misunderstandings. This study applies the conceptual framework model to investigate student difficulties in the knowledge integration perspective. The results are used to guide the design of a concept test that targets the…

Genetics as a core concept of life science is essential for understanding biology. Examining genetics understanding among biology majors is becoming important since they must necessarily achieve some level of genetics understanding to advance their career. This study compares Indonesian biology majors' genetics understanding with previously…

This study aims to evaluate the psychometric properties of the developed diagnostic assessment test and to identify student misconceptions in science in terms of school grades. 153 students were gathered by using random sample from 10th to 12th grade in senior high schools. The 32 items of the two-tier multiple-choice diagnostic test were…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

We investigated the influence of context on students' understanding of cross products of vectors using three isomorphic multiple-choice tests asking for the direction of a cross product in different geometrical settings. One version of the test involved the Lorentz force, the second version involved the torque on an electric dipole, and the third…

The impacts of a technology-integrated formative assessment technique on students' conceptual and procedural knowledge in studying chemical equilibrium are studied in this study. To attain the purpose, a quasi-experimental pretest-posttest strategy nested with a qualitative study method was adopted. The study has three groups: two experimental and…

This study examined the existence of latent classes in TIMSS 2015 data from three countries, Singapure, Turkey and South Africa, were analyzed using Mixture Item Response Theory (MixIRT) models (Rasch, 1PL, 2PL and 3PL) on 18 multiple-choice items in the science subtest. Based on the findings, it was concluded that the data obtained from TIMSS…
