Drawing, constructing, and explaining a model of a given abstract phenomenon is a challenging task. In this study, students were engaged in the "Project-Based Inquiry Science (PBIS)-Air Quality" learning unit, as part of their chemistry curriculum. The study aim is to determine how well students understand chemistry conceptually after…

Students' science identity has been identified as an important construct that positively influences their learning engagement, persistence, and career intentions in science. This paper reported the process of developing and validating an instrument that can be used to assess high school students' science identity. The development of this…

This paper re-validates middle school students' learning progression of the concept of buoyancy (Gao et al., 2020) by using two-time point data. The previous study developed a four-level learning progression based on data collected at a single time point using cross-sectional design. This single-time-point model of learning progression calls for a…

The aim of this study was to determine the impact of three different software simulations for studying Ohm's law and connecting resistors on students' academic performance. A total of 168 eighth-grade pupils were divided into three groups. The first group used the software containing the simulation with an already created electrical circuit, an…

The purposes of this study were to identify middle school student representations of phase change, explore how they interpret textbook representations, and compare student and textbook representations of phase change. A total of 21 middle school students (12 sixth-graders and nine eighth-graders) voluntarily participated in the study.…

This study evaluated the effectiveness of the Mathematics Infusion into Science Project (MiSP), which integrated science and mathematics in an engaging middle school science curriculum that fostered improvements in science content knowledge, higher-level problem solving, and affective domains related to mathematics. The project design was based…

The objective of this study was to explore the relationships between academic hardiness in science, conceptions of learning science, and science learning self-efficacy among Malaysian middle school students. The respondents were 320 eighth-grade students from two selected Malaysian middle schools. Three questionnaires were used for this survey:…

We applied latent class analysis and the rule space model to verify the cumulative characteristic of conceptual change by developing a learning progression for buoyancy. For this study, we first abstracted seven attributes of buoyancy and then developed a hypothesized learning progression for buoyancy. A 14-item buoyancy instrument was…

This study aims to examine the influence of inquiry-based instruction on eighth-grade male and female students' motivation and engagement in science learning in two public junior high schools in central Taiwan. Mixed-methods methodology was adopted with 60 students (32 males and 28 females) in the experimental group and 56 students (28 males and…

Students' conceptions of learning science and their relations with motive for learning may vary as the education level increases. This study aimed to compare the quantitative patterns in students' conceptions of learning science (COLS) and motives for learning science (MLS) across grade levels by adopting two survey instruments. A total of 768…

This study is aimed at exploring ninth-grade Bhutanese students' views of nature of science (NOS). A total of 389 students from middle secondary and higher secondary schools from the eastern, western, southern and central regions of Bhutan took part in this study. To generate a representative population, a stratified random sampling technique was…
