The pedagogical experiment performed has proved the increase in the educational efficiency achieved by the students learning from the multimedia version of the handbook on "Experiment in chemistry" at the Faculty of Chemistry, Adam Mickiewicz University. The results of the tests checking the students' and teachers' knowledge have shown…

Hands-on, inquiry-based, and relevant to every student's life, "Gourmet Lab" serves up a full menu of activities for science teachers of grades 6-12. This collection of 15 hands-on experiments--each of which includes a full set of both student and teacher pages--challenges students to take on the role of scientist and chef, as they boil,…

This dissertation investigated 1) American L2 learners' perceptual ability to accurately identify Japanese pitch accent, and 2) learners' realization of Japanese pitch accent. This study was conducted to determine whether these abilities could be improved through training. Study 1 tested the ability to identify the accent location (pitch fall)…

Two experiments were conducted to assess an online version of Keller's personalized system of instruction, called computer-aided personalized system of instruction (CAPSI), as part of a blended learning design with regard to course knowledge and critical thinking development. In Experiment 1, two lecture sections of an introduction to University…

Background: Methods for teaching thinking may be described as out-of-context or infusion. Both approaches have potential to raise students' general cognitive processing ability and so raise academic achievement, but each has disadvantages. Aims: To describe and evaluate a theory-based learn to think (LTT) curriculum for primary school students,…

Two experiments examined whether text quality is related to online management of the writing processes. Experiment 1 focused on the relationship between online management and text quality in narrative and argumentative texts. Experiment 2 investigated how this relationship might be affected by a goal emphasizing text quality. In both experiments,…

Science lessons taught via experiments motivate the students, and make them more insistent on learning science. This study aims to examine the effects of cooperative learning on students' academic achievements and their skills in identifying laboratory equipments. The sample for the study consisted of a total of 43 sophomore students in primary…

In the UK, practical work is often seen by teachers as central to both the appeal and effectiveness of science education. Practical work is frequently used in the teaching of science in English secondary schools. One of the reasons for this is that many science teachers see practical work as an essential part of what it "means" to be…

The present study used two letter detection tasks, the classic missing letter effect paradigm and a single word versus familiar word compound version of this paradigm, to study bottom-up and top-down processes involved in reading in normally achieving as compared to low achieving elementary school readers. The research participants were children…

The major focus of this ethnographic study is devoted to exploring the confluence of global and local referents of science education in the context of an urban chemistry laboratory classroom taught by a first-generation Filipino-American male teacher. This study investigates encounters between the teacher and four second-generation immigrant…

Contemporary instructional approaches expect students to be active producers of knowledge. This leads to the need for creation of instructional tools and tasks that can offer students opportunities for active learning. This study examines the effect of a computational experiment as an instructional tool-for Grade 12 students, using a computer…

The steady-state fluorescence anisotropy is employed to study the binding of protein of a model protein, human serum albumin, to a commonly used flavonoid, quercetin. The experiment describes the thermodynamics, as well as the biochemical interactions of such binding effectively.

A simple method for the quantitative determination of photosynthetic pigments extracted from green beans using thin-layer chromatography is proposed. Various extraction methods are compared, and it is shown how a simple flatbed scanner and free software for image processing can give a quantitative determination of pigments. (Contains 5 figures.)

Laboratory experiment is conducted to give the students practical experience with the principles of electronic absorbance spectroscopy. This straightforward approach creates a powerful tool for exploring many of the aspects of quantitative absorbance spectroscopy.

The analysis describes an NMR experiment for the general chemistry laboratory, which employs an unknown imidazole solution to measure the pH values. The described mechanism can also be used for measuring the acidity within the isolated cells.
