This article provides a process to carefully evaluate the suitability of a content domain for which diagnostic classification models (DCMs) could be applicable and then optimized steps for constructing a test blueprint for applying DCMs and a real-life example illustrating this process. The content domains were carefully evaluated using a set of…

Science classroom assessment often requires multilingual learners to demonstrate ideas using only English-language resources. These assessments can provide an incomplete picture of students' knowledge and limit subsequent learning opportunities. Increasingly, science teachers are incorporating translanguaging pedagogies in their instructional…

The objectives of this research are: (1) to develop a flipped classroom learning plan using inquiry-based learning on the topic of substance separation for Grade 8 students, to achieve effectiveness according to the 75/75 criteria; (2) to compare science process skills and learning achievement before and after implementing the developed learning…

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students' conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring…

The Regulations of the Commissioner of Education provide that an intermediate-level science test is to be administered in Grade 8 to serve as a basis for determining students' need for academic intervention services in science. The New York State Grade 8 Intermediate-Level Science Test consists of two required components: a Written Test and a…

This study focused on the relationships between teacher characteristics and students' mathematics achievement in EU countries, including Hungary, Italy, Lithuania, Malta, Slovenia, Sweden, and Turkey, which are the only EU countries participated in TIMSS 2015 at the eighth-grade level. The data consisted of the sample of 31,969 eighth-grade…

When individuals' attention shifts away from the primary tasks they are involved in, their minds start to wander. This mental phenomenon, also known as mind-wandering, can interact with other variables and affect the performance of academic tasks. The current study focuses particularly on the mind-wandering (MW) of Omani students while they were…

Although Christians comprise the majority of the population in the United States, they make up less than one third of the scientific community. This underrepresentation is attributed to the desire to avoid the secular culture in academia or self-selection due to a perceived incompatibility or belief in negative stereotypes of Christian scientists.…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…

Systems thinking (ST) is an essential competence for future life and biology learning. Appropriate assessment is critical for collecting sufficient information to develop ST in biology education. This research offers an ST framework based on a comprehensive understanding of biological systems, encompassing four skills across three complexity…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

The Regulations of the Commissioner of Education provide that an intermediate-level science test is to be administered in Grade 8 to serve as a basis for determining students' need for academic intervention services in science. The New York State Grade 8 Intermediate-Level Science Test consists of two required components: a Written Test and a…

The ultimate aim of this research was to explore the contribution of teacher preparedness or readiness (in terms of their academic background, confidence in teaching science and career satisfaction) towards the achievement in science among Malaysian and Singaporean eighth-graders. The TIMSS 2011 international assessment of student achievement at…

It was unknown the impact a middle-level agriscience program had on the eighth-grade general science course. This quantitative study was designed to investigate the relationship between student performance on agriscience state assessments and the state DeSSA Science test. It was also unknown the relationship between eighth-grade agriscience and…

In this research, we have explored the possible differences in students' performance in grade nine chemistry exams that could have been influenced by a different instructional approach in grade eight. We compared two groups of students: one group had received a transmissive propaedeutic approach in grade eight (especially related to the memorising…
