This study was carried out to determine the opinions of the pre-service primary teachers about the laboratory report writing in laboratory courses. Data were collected by using an open-ended questionnaire. The sampling of the study consists of 68 pre-service primary teachers who situated at a public university in the northeast of Turkey. Data were…

A plan for national education to train outstanding engineers has been put into practice at Henan Polytechnic University (HPU). Practical education is a basic characteristic of engineering education. This paper proposed ideas and models to reform the mineral processing engineering education system and also described the discipline and the objective…

Undergraduate science courses typically rely on teaching assistants (TAs) to teach introductory laboratory classes. However little research investigates how to support TAs to implement reform-based teaching in undergraduate settings, and in particular, what factors may influence TAs' motivation to teach within reform-based instructional contexts.…

The 21st century student learns and communicates in the virtual world. In order to meet the individual instructional needs of the students, virtual science laboratories should be researched to accomplish the goal. This study evaluated the effectiveness of a virtual chemistry laboratory in enhancing students' conceptual understanding as a…

The core values in medical practice which are essential for the humane outlook of a physician are clubbed within the domain of medical professionalism. Professionalism along with other discipline-independent skills (human skills) is propagated implicitly in medical schools as components of a "hidden curriculum." Evidence suggests a…

Although writing is well established as a high-impact educational practice, scaling that practice is challenging. Writing is a mode of engaged learning, and teaching it requires providing careful attention informed by expertise. These conditions are labor-intensive and expensive, even as public universities are hardly awash in funds. Writing…

Lactone-size identification of [subscript D]-ribonolactone derivatives has been debated for four decades due to complex lactone-ring rearrangements and acetal migration. This laboratory experiment for an upper-division undergraduate organic chemistry laboratory course describes a fast and reliable assignment of lactone-size derivatives from…

A laboratory experiment is described in which students compare two methods for the determination of the calcium content of commercial dietary supplement tablets. In a two-week sequence, the sample tablets are first analyzed via complexometric titration with ethylenediaminetetraacetic acid and then, following ion exchange of the calcium ion present…

A syringe-based, electronic fluid dispenser is described. The device mechanically connects a syringe plunger to a linear slide potentiometer. As the syringe plunger moves, the electrical resistance between terminals of the potentiometer varies. Application and subsequent measurement of a DC voltage between the potentiometer pins is used to track…

Conducting experiments in physics using modern measuring techniques, and particularly those utilizing computers, is often much more attractive to students than conducting experiments conventionally. However, the cost of professional kits in the Czech Republic is still very expensive for many schools. The basic equipment for one student workplace…

The aim of this simple, quick, and safe laboratory exercise is to provide undergraduate students an introduction to nanotechnology using nanoparticle (NP) synthesis. Students are provided two procedures that allow for the synthesis of different yet controlled sizes of silver NPs. After preparing the NPs, the students perform UV-visible…

This advanced undergraduate laboratory experiment involves the synthesis and characterization of a metal-organic framework with microporous channels that are held intact via hydrogen bonding of the coordinated water molecules. The hydrothermal synthesis of Co[subscript 3](BTC)[subscript 2]·12H[subscript 2]O (BTC = 1,3,5-benzene tricarboxylic acid)…

A rapid separation of three photosynthetic pigments (chlorophyll "a" and "b" and xanthophyll) from fern ("Polystichum acrostichoides") is described using microscale solvent extraction and traditional thin layer chromatography that minimizes use of harmful chemicals and lengthy procedures. The experiment introduces…

The instructional lab setting has been found to be dominated by prescribed tasks and pre-prepared lab kits. This was explained by teachers' need to guide students to simultaneously progress through a lab curriculum, which prompts them to standardize the lab experience. Nevertheless, prominent professional associations have persistently called to…

The study aimed to determine the effectiveness of gamifying instruction in the English language proficiency of Grade 8 Filipino ESL students in one University in Bicol, Philippines, that offers Junior High School. The quasi-experimental single pretest-posttest design was used in the study. The researcher-made test which underwent series of…
