This study was aimed to calculate teachers' effective use of time in scientific inquiry lessons. The research was designed as a case study. The study group of the research consists of 5 pre-school teachers determined by the convenient sampling method. Before the study, the participants were taken in-service training program on scientific inquiry.…

Teachers' professional development (PD) is considered to be a topic of interest in science education. This study examines the impact of professional development in science pedagogy (PD in PED) on students' achievement and how it influences teachers' instruction based on the Trends in International Mathematics and Science (TIMSS) 2019. The sample…

VR technology is being widely used in education due to it's a sense of immersion, real-time interaction, and ability to stimulate imagination. However, there is a lack of research comparing students at different stages. This study used a quasi-experimental design involving 73 fourth-grade and 86 eighth-grade students in two schools in northwest…

The present study provides an illustration of how m-learning may be applied in school science contexts while simultaneously evaluating the accuracy and reliability of mobile phone functionality relating to the measurement of sound. The aim of this study is to report on the use of mobile phones as data collection tools in the context of a science…

This study investigated whether students' motivational beliefs about learning science (i.e., self-concept in science and intrinsic value of science) varied significantly across grade levels and genders. The study also examined the relations between students' motivational beliefs about learning science and their science achievement by grade level…

This study analyzed the responses of Korean students to interest, confidence, value, and instructional clarity in science and mathematics. To achieve this, the raw data of the recent student survey of TIMSS were analyzed. A one-way ANOVA was performed, and a post hoc test was performed. Additionally, a cohort analysis was performed to determine…

The purpose of this study is to investigate the extent to which science process skills are represented in the texts and activities in 3rd, 4th, 5th, 6th, 7th, and 8th-grade science textbooks according to the learning areas of the science curriculum. The document analysis method is adopted in the current study. Course contents and activities in…

Improving the reading ability of young students could hardly be a more urgent priority for our elementary schools. Two thirds of American fourth and eighth graders are not able to read proficiently--and the outcomes are far worse for students from disadvantaged backgrounds. The National Assessment of Educational Progress in 2019 showed that only…

The International Association for the Evaluation of Educational Achievement (IEA) Research for Education series represents a further effort by IEA to capitalize on it's unique datasets, so as to provide powerful information for policymakers and researchers. Each report focuses on a specific topic and is produced by a dedicated team of leading…

Contextualized items have been widely used in science testing. Despite common use of item contexts, how the influence of a chosen context on the reliability and validity of the score inferences remains unclear. We focused on sequential cues of contextual information, referring to the order of events or descriptions presented in item contexts. We…

This study aims to conduct a multidimensional analysis of the 2017 Science Curriculum taking the previous three curricula into account. The document analysis technique, which is a qualitative research method, was used. The Science curricula of 2000, 2005, 2013 and 2017 were analyzed in detail for this purpose. The 2017 Science Curriculum, which is…

So far, not enough effort has been invested in developing reliable, valid, and engaging assessments in school science, especially assessment of interdisciplinary science based on the new Next Generation Science Standards (NGSS). Furthermore, previous tools rely mostly on multiple-choice items and evaluation of student outcome is linked only to…

Saudi students' science academic performance has declined as evidenced by (TIMSS). Saudi science teachers are characterized as using the lecture format without considering individual student differences and failing to provide differentiated Method (DM). This paper reports on an effort to help female Saudi pre-service science teachers (PSST)…

Literacy learning clubs are highly motivating small-group collaborations that can improve tweens' and teens' academic achievement, support their social-emotional development, and increase their enjoyment of reading and writing. This book explains the research basis for the author's approach and offers practical instructions for implementation in…

This paper aims to analyze the science curricula which is being implemented in Turkey with respect to spiral curriculum approach. To carry out this analyze 3th, 4th, 5th, 6th, 7th and 8th grade education programs are analyzed correlatively based on qualitative research method. The research findings were analyzed in terms of iterative revisiting of…
