Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

Science education researchers and curriculum documents have advocated scientific inquiry for more than six decades; however, inconsistent findings concerning its effects on students' learning outcomes have been revealed in recent analyses of large-scale international assessment data (e.g., the Programme for International Student Assessment…

This study investigated the relationships of teacher-directed approaches with science achievement in Australian schools. The data for this study were drawn from the Program for International Student Assessment (PISA) 2015 database and analysed using multilevel modelling (MLM). MLMs were estimated to test the contribution of each item to students'…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

Science education is essential for sustainability and prosperity. However, students from rural communities, arguably the future custodians of our environment and significant drivers of our economies, underperform in science education. In Australia, rural students generally lag behind metropolitan students in science achievement and engagement.…

Students' out-of-school science participation has been identified as a factor that supports adaptive science outcomes. Researchers have largely investigated students' out-of-school science participation in terms of structured science activities (e.g., attending a science camp), with far less consideration of how students' involvement in…

In recent years, self-theories such as growth mindset and resilience have gained interest as they have a sizable influence on achievement and school-related motivation. The aim of this study is to investigate the relationship between immigrant students' growth mindset, resilience, and science achievement in PISA 2018 by considering the mediating…

Australia participated in the eighth cycle of the Trends in International Mathematics and Science Study (TIMSS). TIMSS is an international sample study that assesses the mathematics and science achievement of Year 4 and Year 8 students every 4 years. Australia has participated in all cycles of TIMSS since it commenced in 1995 and over this 28-year…

There has been a strong narrative in Australia of falling attainment in high school science, with much of the campaign informed by results from international standardised tests such as Programme for International Student Assessment (PISA), which shows a year-on-year decline in scientific literacy of Australian 15-year-old students. These results…

This study aims to determine the effectiveness of flipped classrooms in science education through the use of systematic review and meta-analysis. A total of 64 studies were analyzed by scanning the following databases: Web of Science, Eric, Taylor & Francis, and Education Full Text (EBSCO). Of the studies analyzed, 18 were selected for…

Intensive mode delivery (IMD) of subjects and courses offer a flexible option for today's diverse student body, many of whom juggle work and carer responsibilities alongside study. However, little focus has been placed on the detailed design of IMD for different teaching roles. Responding to a call for science specific data, we investigated…

In this 21st century context, communities and nations cannot afford to lose the talents of any young people. Shifts in thinking and practices are needed: from one-dimensional definitions to varied talents and 21st century skills of creativity, critical thinking, collaboration, and communication; from identification to assessment; from the goal of…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study of student achievement directed by the International Association for the Evaluation of Educational Achievement (IEA). TIMSS was first conducted in 1995 and the 2023 assessment formed the eighth cycle, providing 28 years of trends in mathematics…

This experimental-mixed methods investigates the impact of shifting from a traditional laboratory model to a hybrid laboratory model. The hybrid model consisted of (1) online instructions and pre-laboratory test, (2) compressed face-to-face laboratory time, and (3) post-laboratory data analysis. This study analyses whether student perceptions of a…

This paper uses data from the OECD's 2015 PISA and an endogenous treatment effects model to investigate the impact of different intensities of digital device use for academic purposes on science learning outcomes. When we do not differentiate the location of device use, we find that greater use can help students improve their science scores in…
