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,…

One main obstacle for instructors in inviting students to design knowledge construction is the tension between prioritizing students' ideas and maintaining the scientific validity of the activity. In this study, as a way of supporting students in shaping their own knowledge construction, the establishment of an audience for knowledge was enacted…

States and school districts in the USA have begun to create and implement curriculum to promote elementary students' nascent STEM-related interests and to generate their initial knowledge of careers in those fields. Evaluating the efficacy of such interventions warrants valid and reliable tools, which are not presently available for middle…

STEM education is present in most recent curriculum reforms around the world. One of the main novelties of this educational movement is the integration of engineering practices into science education. In the Spanish educational context, this implies an important challenge for science teachers. So, this study analyzes whether secondary science…

Questioning is a critical strategy for science teachers to scaffold students' exploration and knowledge construction in inquiry-oriented science teaching. In science teacher preparation, open-ended questions asked by teachers are advocated as an advantageous strategy to prompt student thinking. However, insufficient attention has been cast on how…

Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to…

Teachers play a key role in moving reform-based science education practices into the classroom. Based on research that emphasizes the importance of teachers' affective states, this study aimed to explore the constructs pedagogical discontentment, science teaching self-efficacy, intentions to reform, and their correlations. Also, it aimed to…

We used the Rule Space Model, a cognitive diagnostic model, to measure the learning progression for thermochemistry for senior high school students. We extracted five attributes and proposed their hierarchical relationships to model the construct of thermochemistry at four levels using a hypothesized learning progression. For this study, we…

Science communication competence (SCC) is an important educational goal in the school science curricula of several countries. However, there is a lack of research about the structure and the assessment of SCC. This paper specifies the theoretical framework of SCC by a competence model. We developed a qualitative assessment method for SCC that is…

This paper is part of a larger study that aims at highlighting students' interpretations of the idea of the "Balance of Nature", as well as its use in their reasoning about the future of an ecosystem, in order to subsequently develop a learning environment that might promote a reconsideration of its validity and usefulness. Our focus…

This study developed two testing devices, namely the animation-based test (ABT) and the graphic-based test (GBT) in the area of earth sciences covering four domains that ranged from astronomy, meteorology, oceanography to geology. Both the students' achievements of and their attitudes toward ABT compared to GBT were investigated. The purposes of…

An elementary version of the "Questionnaire on Teacher Interaction" (QTI) and a scale for determining students' "Enjoyment of their Science Lessons" (ENJ) were translated into Standard Malay. This process, together with its initial validation carried out in 136 classrooms with 3,104 students, is described in this paper.…
