Outreach science labs aim to promote students' interest. Previous research has often suggested that performing experiments in such labs has a positive effect on their interest. However, these studies often lack a comparison to the effects of performing them at school. This research gap was addressed in the present study. The sample consisted of…

This study embarked on the development of a comprehensive Junior High School Biological Inquiry Experiment Manual. This manual was utilized in a research initiative involving 30 students in the control group and an equal number in the experimental group. Rigorous data analysis techniques, encompassing mean values, standard deviations, paired…

In this quantitative study, we explored learners' intrinsic motivation towards three different experimental physics educational activities offered by our department to upper-grade high school students. The inspected activities were lecture demonstrations, a science show, and hands-on practical work. The respondents were Czech high school students…

Crystal materials are an important pillar of advanced technology. Among them, the preparation of large-sized single crystal materials is of great importance for their practical application. Herein, we select the well-known nonlinear optical crystal KH[subscript 2]PO[subscript 4] and impressive deep-blue colored crystal CuSO[subscript…

Our study evaluates students' approaches to and perceptions of the use of hands-on at-home laboratory kits (HALK) experiments, open-source computer-based simulations (OSCBS), and their combination (OSCBS-HALK) in undergraduate introductory asynchronous online physics courses. Anonymous survey data from students who had completed online physics…

A two-week summer camp was designed, implemented, and then updated for high school students focusing on organic chemistry, solar energy, and green chemistry principles. Students learn about laboratory safety, perform organic reactions, go on field trips, and take part in interactive lessons that focus on both fundamental chemistry topics as well…

Affective and cognitive outcomes of science teaching in schools may be enhanced by science outreach labs (SOLs). Particularly interesting is whether and how to connect SOL visits to in-school science learning. Recent studies--among others, in this journal--have confirmed SOLs' positive affective effects. However, research remains inconclusive…

Smartphone-based experimental exercises were incorporated as part of the homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning…

A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…

This research aimed to explore the effects of a virtual lab (VL) and a Microcomputer-based Lab (MBL) on students' performance in scientific modeling. A web-based virtual lab and a low-cost MBL were proposed to help first-year engineering students build scientific models. Empirical research was done in a slope motion experiment. The participants…

This research aimed to reveal the opinions of the university students who conducted original educational videos context for the experiments in the Biochemistry laboratory course. Participants were fourth year students (N=40) of the Mathematics and Science Education Department, in Chemistry Education Program. A case study was used and carried out…

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…

Experiments in different forms can certainly be suitable tools for increasing student interest in physics. However, educators continuously discuss which forms of experimenting (if any) are the most beneficial for these purposes. At the Faculty of Mathematics and Physics, Charles University, Prague, two different forms of physics experiments are…

Incorporating research-based lab activities into general chemistry at a large university can be challenging, considering the high enrollments and costs typically associated with the courses. Performing sweeping curricular overhauls of the general chemistry laboratory can be difficult, and in some cases discouraged, as many would rather maintain…

Science instruction literature provides us with goals for laboratory instruction and guidelines for designing and implementing science labs in the post-secondary setting. How well are we doing in our attempt to provide a meaningful and positive learning experience for our students? This paper describes the results of a study to determine whether…
