In Content and Language Integrated Learning (CLIL) programmes, students learn content knowledge and a second/foreign language (L2) simultaneously. It follows that both content and language are assessed, although research on how to do so remains scarce. This study explores the interplay between cognitive and linguistic demands of CLIL assessments.…

Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

Evidence-Based Reasoning (EBR) is a framework of inquiry-based teaching for developing scientific reasoning. This research aims to analyze the effectiveness of EBR in inquiry-based Physics teaching to improve students' scientific reasoning. Applying Slovin formula for sample determination, the research involved 139 upper-secondary school students…

People's diminished awareness of plants, affected by anthropogenic environmental deterioration, has challenged science education to overcome the obstacles impeding a better understanding of their meaning and value. The aim of this study was to investigate the influence of the socioeconomic status of high-school students, as indicated by their…

In this article, the author describes a chemistry gas experiment that she developed with the intent of integrating inquiry and Problem-Based Learning (PBL). The lab activity follows the principles of Ambitious Science Teaching (AST). Teachers (1) engage students with important science ideas, (2) elicit students' ideas while making visible what…

Research has shown that the objectives for laboratory teaching--just as with other teaching methods--are often not achieved and that many laboratory sessions are ineffective and yet expensive in terms of pupil and teacher time, and facilities. There are several reasons for this, but one reason is that instructions for many lab activities are too…

The aim of this study was to examine the effectiveness of science-technology-society (STS) approach based worksheets on improving Indonesian students' scientific literacy of 'environmental pollution' topic. Through quasi-experimental research method (nonequivalent pre-post control group design), the sample of the study comprised of 64 junior high…

For a scientific educational approach toward empathy, this study newly defined empathy in science as "empathy with a problematic situation and other people." In 6 competency frameworks, content related to empathy was extracted, and exploratory factor analysis was conducted through an online survey of 150 teachers. Three factors of…

Secondary school science teachers report that their approaches to some topics are affected by the recognition that some pupils hold religious beliefs, while primary school teacher trainees express concern about teaching evolution to children with a religious faith. Pupils in British schools and internationally often assume a conflict between…

This study was carried out to investigate pre-service teachers' perceived ease of use, perceived usefulness, attitude and intentions towards the utilization of virtual laboratory package in teaching and learning of Nigerian secondary school physics concepts. Descriptive survey research was employed and 66 fourth and fifth year Physics education…

Cruise planning may seem like an ordinary task for oceanographers, but it actually involves logical and strategic thinking, collaboration, and multidisciplinary work. The "Challenger" expedition, led by Charles Wyville Thomson from 1872 to 1876, was the first to be fully dedicated to understanding oceans (Rice et al. 1999) and was…

Physics educators today face two major challenges: supporting the acquisition of a solid base of conceptual knowledge and reducing the persisting gender gap. In the present quasi-experimental study, we investigated the potential of physics instruction that is enriched with evidence-based cognitively activating methods, such as inventing with…

This paper reports on a study of teacher support in experimental computer-supported collaborative learning (CSCL) settings where students engage with graphs in real-time labs within the context of school science. Real-time labs are digital devices and software connected to student-controlled sensors or probes that can measure and visualize data…

Constructing student's scientific literacy is still a challenge for the developing country. PISA 2015 report on scientific literacy showed that Indonesia was positioned at 62th out of 70 countries. According to this result, the students are only able to explain the simple science phenomenon because some learning activities have not followed good…

A Rube Goldberg device is a complicated, yet comically involved machine that performs a simple task such as closing a door, watering a plant, or typing a key on a keyboard. Creating one is an open-ended activity that challenges students to use prior knowledge, resourcefulness, investigatory skills, and imagination. This reverse engineering…
