The main objective of this four-year empirical research project has been to develop the experimental design skills of 12-16 year-old Hungarian pupils in Grades 7-10 of junior high school through guided inquiry, using six chemistry experiment worksheets each school year. Group 1 (control group) and Group 2 follow step-by-step instructions, but…

The physics' subject aims to provide the student with a broad understanding of the physical phenomena that occur around them every day and introduce them to the scientific search. The use of experiments in the teaching of the subject contributes to the understanding of these phenomena, the development of skills and critical thinking and has many…

This study investigated the interrelationships among science process skills (SPSs) developed through home-based experiments (HBEs) and examined the correlation between SPS and science literacy (SL) among middle school students. Employing a qualitative correlational design, the study involved 77 seventh-grade students in Aceh Province, Indonesia.…

A new experiment using laser ablation with inductively coupled plasma mass spectrometry (LA-ICP-MS) was designed for chemistry undergraduate students. While most analytical methods only provide information on the amount of the analyte, LA-ICP-MS allows extra information on the distribution of the element in the sample. Because it achieves…

Historical scientific controversies have great potential to address aspects of the nature of science in context. This paper describes a design case about a novel lesson plan based on the scientific controversy between Karl von Frisch and Carl von Hess on the sight of bees (how they see). This lesson plan allows concepts related to experimentation,…

Wheat powdery mildew is an important fungal pathogen of wheat with an obligatory biotrophic lifestyle (a parasite that can only develop on a living host). We investigated the genetics of this host-pathogen interaction by using phenotyping and PCR assays to detect genes in both wheat and powdery mildew, which are known determinants of the outcome…

Electrophilic aromatic substitution (S[subscript E]Ar) and nucleophilic aromatic substitution (S[subscript N]Ar) reactions are among the most valuable reactions in the conversion of aromatic rings. While these reactions are typically covered in separate experiments in undergraduate organic courses, a continuous experimental setup elucidating both…

A laboratory experiment that involves the aqueous and solid phase synthesis, characterization, and solvatochromic properties exploration of red complex [Ni(Me[subscript 3]en)(acac)]BPh[subscript 4] has been developed for first-year undergraduates in the College of Chemistry and Chemical Engineering at Xiamen University. In contrast to previously…

The curriculum for undergraduate Agricultural Engineering does not usually include much laboratory practice. In order to address this, here we propose the design of a practical class on legume-rhizobia symbiosis, using an interdisciplinary approach that takes elements from botany, agriculture, and microbiology. The students perform an assay to…

Technological development, particularly in experimental, is now embedded in physics textbooks. Therefore, this study analyzed how the basic inquiry and the integrated science process skills in digital-related experiments are distributed within physics textbooks of South Korea, the United Kingdom, and Indonesia. A descriptive qualitative content…

This article describes the design, implementation, and evaluation of the gamification of laboratory activities in a General Chemistry course at the Federal University of Ceará in Brazil. In the gamified laboratory, seven experiments traditionally performed in the course were transformed into ten missions, incorporating game elements such as…

This case study investigated the conceptual understanding of the Simple Pendulum topic amongst physics student-teachers using online experiments. A pre-experimental design was utilised, employing a one-group pretest-posttest approach with 20 student-teachers. The research instruments included a highspeed video activity conducted within Online…

Science, technology, engineering, and mathematics (STEM) project refers to experiments conducted to address problems, make improvements, or discover new things in those fields that can be tested using the scientific method. This paper describes a long-term STEM project in which pre-service science teachers (PSSTs) have a chance to discover new…

Potash, an essential raw material of the 18th century, used to be produced from the ashes of plants. Known since antiquity, it was in 1807 that Humphry Davy put an end to the decades-long controversy about its nature as a compound. The technology behind potash production was implemented in Brazil by the Portuguese naturalist Frei Velloso. The…

There is a large variety of goals instructors have for laboratory courses, with different courses focusing on different subsets of goals. An often implicit, but crucial, goal is to develop students' attitudes, views, and expectations about experimental physics to align with practicing experimental physicists. The assessment of laboratory courses…
