This study aims to describe the 3D model's online modules effectiveness in the practicing mastery of conceptual knowledge in solar system learning using an instrument which tested 58 7th-grade respondents from one of the junior high schools in Jombang, East Java, Indonesia. The respondents were then divided without randomization into 29…

The COVID-19 epidemic had caused one of the most significant disruptions to the global education system. Many educational institutions faced sudden pressure to switch from face-to-face to online delivery of courses. The conventional classes are no longer the primary means of delivery; instead, online education and resources have become the…

The purpose of this study is to examine the effect of the flipped learning model (Staker & Horn, 2012), which is one of the types of rotation model in the sub-level of blended learning models, on students' understanding of the nature of science and their achievements. In the study, the mixed research method, which allows the quantitative and…

The aim of this paper was to investigate chemistry teachers' attitudes towards certain characteristics of the nature of science and history and philosophy of science, and the influence of those views on their teaching practice. The sample comprised 272 chemistry teachers. A questionnaire was used for data collection. Most teachers recognised some…

Newtonian mechanics is still among the most difficult topics in the physics' syllabus taught at school. For example, even after completing traditional instruction, students still think that a force is necessary to maintain motion. Therefore, a revised method of instruction is needed that meets students' learning needs. The aim of the project…

This research aimed to explore the possibility of using Content and Language Integrated Learning (CLIL) approach for the development of students' Second Language (L2) skills and content in the subject of Chemistry. To achieve this purpose, action research method was used to implement CLIL approach at grade 7 consisting of 30 students. The research…

The increase in global migration and the prioritization of English as an international language have resulted in science learning environments that include students whose primary language differs from the language of instruction. This worldwide phenomenon is not limited to geographical regions but occurs where diverse populations representing…

We investigate how technologies that automatically score student written essays and assign individualized guidance can support student writing and revision in science. We used the automated scoring tools to assign guidance for student written essays in an online science unit, and studied how students revised their essays based on the guidance and…

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…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

In this study, 7th grade students were observed completing a series of lessons in an online science course to explore their thinking and strategies for: (1) using curriculum resources for learning, (2) developing thinking and strategies for self-assessing "assessment readiness," and (3) exploring the relationship between resource use and…

This research is conducted among 65 seventh graders (12-14 years old) who attend introductory course on physics. Tests and interviews are used to trace the roots of the students' misconceptions about mass. Results from the research reveal serious weaknesses in students' understanding of concept of mass, and its confusion with concepts of density…

In this study 7th grade students were observed completing a series of lessons in an online science course to explore their thinking and strategies for using curriculum resources for learning, to explore their thinking and strategies for self-assessing their readiness for lesson assessment, and to explore the relationship between resource use and…

Online learning has seen an explosive growth at the K-12 level, however little research has used an experimental design approach to specifically examine the outcomes of delivery methods. This study examines what effect learning in an immersive learning environment (virtual world) has on student achievement and satisfaction with the lesson. To…

Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…
