This study explored how peer feedback after hands-on scientific inquiry (SI) activities affected students' SI competence over time (6 weeks) by implementing an after-school intervention program in which 188 Chinese ninth-grade students (14-16 years old) participated during their first semester. A between-subject experimental design was used for…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

Textbooks use images, in addition to text, for delivering knowledge, thereby convey attitudes and values of students including those on gender bias. The gender bias presented in textbook images affects in subtle ways the students' learning outcomes, career choices, and how they perceive science. However, prior research has relied on explicit…

Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

Background: Inquiry-based learning has been widely adopted in educational practice especially in science education. Scaffolding plays an important role in fostering learning in sophisticated inquiry. Meanwhile, it is important not to undermine the open-endedness of inquiry activities and the nature of student-centred learning. Purpose: This study…

In science education, chemistry is a discipline that involves macroscopic matter and microscopic particles. It is difficult for the traditional teaching approach to help learners comprehend abstract chemical knowledge. Researchers have attempted to use Virtual Reality (VR) to help learners realize meaningful knowledge via visualizing the learning…

The Performance Expectations described in the Next Generation Science Standards (NGSS) pose significant challenges for assessment design. Multiple models of assessments, including paper-and-pencil and hands-on based performance assessments, can be utilized to assess student competency while applying scientific and engineering practices, in the…

This paper presents a revised learning progression for the energy concept and initial findings on diverse progressions among subgroups of sample students. The revised learning progression describes how students progress towards an understanding of the energy concept along two progress variables identified from previous studies--key ideas about…

Digital game-based learning has received increased attention in education. As the key stakeholders in education, students, parents, and teachers may have different perceptions and attitudes towards game-based learning, which have a great impact on its adoption and dissemination. However, there is a lack of research examining how the perceptions of…

Few studies, if any, have systematically investigated the connection or relationship between geography curriculum and scientific literacy. With this realization, in this article, we examined the potential contribution of geography curriculum to developing students' scientific literacy, with China's middle-school geography curriculum as an example.…

Background: Students' daily-life experiences may render favorable effects on the students' affective domain like interest, enthusiasm, motivation, joy, curiosity, awareness, and eagerness to learn science as not commonly found in the classroom environment. However, no rigorous research has been reported on those aspects in Mainland China despite…

Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at…

This study investigates the representations and understandings of electric fields expressed by Chinese high school students 15 to 16 years old who have not received high school level physics instruction. The physics education research literature has reported students' conceptions of electric fields post-instruction as indicated by students'…
