This study aims to fill the gap in teacher education by examining the effect of design-based STEM activities on pre-service science teachers' design thinking skills and evaluating their design-based learning process experiences. An explanatory mixed design that includes both qualitative and quantitative data was used as the research method. The…

The Many-Facet Rasch model is frequently used to analyse and minimize disparities in rater (judge) severity in performance evaluations, in which raters assign scores to test-takers' performances. In this research, the aim of the present study was to analyse science teacher candidates' laboratory activities by using the Many-facet Rasch model.…

HOTS is one part of the skills that need to be developed in the 21st Century . This study aims to determine the characteristics of the Fundamental Physics Higher-order Thinking Skill (FundPhysHOTS) test for prospective physics teachers using Item Response Theory (IRT) analysis. This study uses a quantitative approach. 254 prospective physics…

This study aims to determine the perceptions of the use of scientific process skills of in-service and pre-service teachers working in branches related to science courses in secondary and high schools. Therefore, this research was designed based on a relational survey model and was carried out with 150 science teachers in Turkey and 260…

Innovative instructional technologies, especially virtual reality devices, are becoming more prominent and feasible in science education. Concerning science laboratories, activities enriched with virtual reality technology have the potential to make unobservable phenomena accessible in any school. This virtual reality technology has the potential…

Preparing pre-service science teachers (PSSTs) with the scientific research skills (SRSs) is an ultimate aim of PSSTs' programs. This study aimed to explore PSSTs' understanding level of SRHs (SRHUL). To this end, an action research (AR) was adopted using a pre-post-test design. In doing so, a multiple choice test which consists of 15 items was…

This study explored the effect of conventional laboratory practical manuals on pre-service teachers' integrated science process skills (ISPS). A validated multiple-choice questionnaire with the ISPS components was used to collect data. No significant difference between pre-service subject-specific teachers' (biology, physics and chemistry) ISPS…

In this study, 24 experienced in-service teachers' science process skills (SPSs) development and their use of SPSs in their lesson plan through a week-long professional development (PD) supported by the Scientific and Technological Research Council of Turkey (#117B302) were studied. SPSs are important part of scientists' work, scientific literacy,…

This study provides an example of a systematic professional development project designed to build capacity for the teaching of nature of science and scientific inquiry, while not sacrificing the learning of more traditional science subject matter. Specifically, this project examined the impact of a 5-year professional development project on K-12…

Focusing on the science knowledge and pedagogical content knowledge that teachers need to realize the vision of the Next Generation Science Standards (NGSS) in their classrooms, this article presents findings from efforts to (a) adapt existing criteria and design heuristics for educative features of curriculum materials and apply them in the…

Purpose: This study investigates how senior science teachers viewed the effects of a Raising Test Scores policy and its implementation on instruction of higher order thinking (HOT), and on teaching thinking to students with low academic achievements. Background: The study was conducted in the context of three concurrent policies advocating: (a)…

This study had two research purposes. First, we examined the scientific reasoning gains of prospective science teachers who are concrete, formal, and postformal reasoners in an argumentation-based physics inquiry instruction. Second, we sought conceptual knowledge and achievement gaps between these student groups before and after the instruction.…

The objectives of this research were to develop innovation curriculum and study the effect of curriculum usage in science teachers' training in establishing the supplementary subject curriculum for action lesson. It focuses on science process skills with 10 teachers for 4 days, and 236 Grade 9 students from 10 schools during the first semester of…

Systematic studies on effectiveness of in-service teacher professional development (PD) are important for science education research and practice. Previous studies mostly focus on one certain aspect of the entire program, for example, effectiveness of PD on improvement of teachers' knowledge or students' learning outcomes. This study, however,…

This study developed learning progression-based measures of science teachers' content knowledge (CK) and pedagogical content knowledge (PCK). The measures focus on an important topic in secondary science curriculum using scientific reasoning (i.e., tracing matter, tracing energy, and connecting scales) to explain plants gaining weight and…
