Improving the interest of high-school students towards chemistry (and science in general) is one of the goals of the Italian Ministry of Education. To this aim, we designed a context-based activity that actively involved students in six different laboratory experiences interconnected by a case study of the murder of Miss Scarlet, from the famous…

This study investigated whether or not lab type, traditional lab or virtual lab, influenced students' engagement. To measure student engagement six students were videoed over the course of an 18-week semester while conducting 10 lab experiments. To analyze student engagement, a systematic visual comparison in the tradition of single case research…

The purpose of this research was to study the system of resources, the objectives of their use and the factors that affect the selection and integration of the different resources by Lebanese secondary physics teachers in their teaching in general and for teaching Electricity in particular. For this aim, a qualitative approach was used and the…

In this research, the laboratory perceptions of pre-service science teachers with different goal orientations in analytical chemistry courses in which an inquiry-based laboratory approach had been adopted were examined in a case study. From the pre-interviews conducted with 37 pre-service science teachers, 3 preservice science teachers with…

This article analyzes masculinity and experimental practices within three different physics communities. This work is premised on the understanding that the discipline of physics is not only dominated by men, but also is laden with masculine connotations on a symbolical level, and that this limited and limiting construction of physics has made it…

This study was conducted within the scope of the General Biology Laboratory II course, which was taught in the Science Teaching Department in the Spring semester of the 2016-2017 academic year. The study group consisted of 40 teacher candidates in their second year in the Science Teaching Department at a state university in Konya. The purpose of…

This work developed the Flint, Michigan water crisis as a modular case study for teaching traditional analytical chemistry concepts through the medium of environmental justice, power, and equity. An interdisciplinary framework was used to design, implement, and assess the case study in an effort to understand how the deliberate presence of…

Analyzing protein structure has become an integral aspect of understanding systems of biochemical import. The laboratory experiment endeavors to introduce protein folding to ascertain structures of proteins for which the structure is unavailable, as well as to critically evaluate the quality of the prediction obtained. The model system used is the…

Social media are a highly visible factor in the daily lives of our students. Why should teachers not take advantage of this and develop teaching and learning materials that use the designs found in such media to contextualise science learning? This article suggests some ideas for creating lab instructions using social media design as an innovative…

The science education literature documents the benefits of student engagement with scientific practices. Lab reports could be an opportunity for developing student reasoning, but often prioritize learning terminology and genre-specific writing. There is potential for instructors to give students feedback that helps them to engage with scientific…

In the Community-Based Inquiry (CBI) instructional method, cooperative student groups complete case study activities based on scientific literature and conduct their own laboratory investigations that address authentic community needs. This study compared critical thinking and content knowledge outcomes between traditional Introduction to…

We present a practical activity focusing on two main goals: to give learners the opportunity to experience how the scientific method works and to increase their knowledge about enzymes in everyday situations. The exercise consists of determining the amylase activity of commercial detergents. The methodology is based on a qualitative assay using a…

The students in working in laboratories in 21st century are preferred to take place as active participants in the experiments coming up with their own designs and projects by developing new ideas and problems rather than implementing the ones told and ordered by others during these experiments. The science teachers that would have the students…

A case study approach was used to examine the potential knowledge-transforming role of writing with 27, Year 12 chemistry students'. The study was prompted by changes to external chemistry examinations that required students to write connected discourse, and supported by the chemistry teacher's belief in the instructional value of…

Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…
