Science assessments should evaluate the full complement of inquiry practices (NGSS, 2013). Our previous work has shown that a large proportion of students' open responses did not match their scientific investigations (Li et al., 2017a). The present study both unpacks and compares the sub-components underlying students' performance for…

In the research, the purpose was to implement and evaluate an interdisciplinary curriculum that aimed at developing social sciences pre-service teachers' understanding and knowledge about the nature of science. This research was based on case study design. In order to collect the research data, the methods of observation, interview and document…

This paper describes a project carried out in a sophomore chemical engineering course, in which students studied the energetic differences between refining and recycling aluminum. They worked in teams to prepare a presentation about the importance of aluminum recycling to a lay audience. The project reinforced classroom learning and provided an…

One challenge for the introductory physics teacher is incorporating calculus techniques into the laboratory setting. It can be difficult to strike a balance between presenting an experimental task for which calculus is essential and making the mathematics accessible to learners who may be apprehensive about applying it. One-dimensional kinematics…

Increasingly, the science education community has recognized the need for curriculum resources that support student development of authentic scientific practices, rather than focusing exclusively on content knowledge. This paper proposes a tool for teachers and researchers to assess the degree to which certain curriculum resources and lessons…

This study was conducted in order to analyze the relation between analytical thinking skill and scientific argumentation in physics learning. The study was conducted with the interactive CK 12 simulation about optics. The sample of the study consists of 28 randomly selected students in Yogyakarta, Indonesia. The data was collected using pre and…

The important role of self-efficacy (SE) in students' motivation, engagement, persistence, and academic achievements has been reconfirmed by ample research, both in general and for STEM disciplines. As most studies focused on traditional school systems, additional research is needed on how science SE develops in different educational environments,…

The authors share a sequence of lessons that teachers thought were especially useful to produce effective science discourse and promote student understanding. The first lessons teach social and emotional skills. The later lessons focus on energy sources and systems, requiring students to apply their social and emotional skills to conversations…

Assessment, including course exams, clearly indicates to students what learning goals they are expected to master in a certain course. However, most of these assessments tend to focus on generating a correct answer rather than on the type of reasoning or skills used to arrive at the answer. If educators value skills in addition to the correctness…

A hands-on experiment to obtain atomic and ionic radii with lumps of metal and ionic compounds is reported here. The experiment is performed with industrial-grade typical metals (iron, copper, aluminum, and lead) and single-crystal lumps of ionic compounds (sodium chloride, potassium chloride, and potassium bromide). Students measure the dimension…

Some educators use what we call a "hook" as a key element in their lessons. We use "hooks" to get our students interested in what it is we are teaching. Many teachers have adopted the Next Generation Science Standards and establish the phenomena as the engine that drives scientific investigation and learning in the classroom.…

Using many-facets Rasch measurement, this study aimed to detect and measure disciplinary context effects on student hands-on performance in terms of scientific inquiry competence. In Shanghai, China, a total of 251 eighth graders, from five junior high schools, participated in this study. The partial credit Rasch model was applied to help…

This study aimed to determine the differences in science process skills in each class in the Physics Education Study Program. This research was a quantitative study with a comparison design. The sample was 108 students with details of 54 control class students who used conventional guidebooks, while the control class totaling 54 students used a…

Self-efficacy, the belief in one's ability to succeed in learning tasks, predicts learning and success in education broadly and physics specifically. While self-efficacy increases for students in most introductory science and mathematics courses, self-efficacy consistently decreases for women in physics courses. This study used the experience…

Understanding of causal mechanisms has largely been ignored in past work on science learning, with studies typically assessing multiple aspects of children's knowledge or focusing on their explanations without differentiating between accounts of factors, variables and mechanisms. Recent evidence suggests that grasp of mechanisms is in fact a…
