The purpose of this study is to investigate the effects of Field Dependent (FD)/Field Independent (FI) cognitive styles and motivational styles on high school students' conceptual understandings about direct current circuit concepts. The participants of this study consisted of 295 high school students (male = 127, female = 168) who were enrolled…

This study investigated the relevance of multi media skills in teaching and learning of scientific concepts in secondary schools. Self constructed questionnaire was administered to 120 students randomly selected in four secondary schools in Ojo Local Government Area of Lagos state. Data generated were analyzed using chi-square statistical…

Graphene's unique combination of exceptional mechanical, electronic, and thermal properties makes this material a promising candidate to enable next-generation technologies in a wide range of fields, including electronics, energy, and medicine. However, educational activities involving graphene have been limited due to the high expense and…

In response to the concern of the need to improve the scientific skills of school children, this study investigated the influence of text design (in terms of text cohesion) and individual differences, with the aim of identifying pathways to improving science education in early secondary school (Key Stage 3). One hundred and four secondary school…

This paper presents a profile on how teachers in senior secondary schools in Bauchi state Nigeria utilise animated instructional resource (AIR) in the teaching of biology. A structured questionnaire used to generate data on the availability, accessibility and application of the AIR for classroom instruction by teachers. The instrument for data…

The Electrochemical Pen (EChemPen) was developed as an attractive tool for learning electrochemistry. The fabrication, principle, and operation of the EChemPen are simple and can be easily performed by students in practical classes. It is based on a regular fountain pen principle, where the electrolytic solution is dispensed at a tip to locally…

This study examined the effectiveness of computer-assisted instruction on Student Team Achievement Division (STAD) and Learning Together Model (LTM) cooperative learning strategies on Nigerian secondary students' achievement and motivation in physics. The efficacy of Authors developed computer assisted instructional package (CAI) for teaching…

Many students feel the curriculum is detached from their lives and interests. Indeed, about half the questions asked by high school biology students are not addressed by the curriculum. This study presents a strategy to incorporate students' curiosity questions into the curriculum as a way to reduce the disparity between students' interests and…

We noted last month that Hispanic and African-American seniors were less likely to have taken a high school physics course than their peers, and we suggested that socioeconomic status (SES) played a role in the lower participation. Often the proportion of students receiving free and reduced-price meals (FRMs) is used as a measure of SES in…

The ability to represent the world like a scientist is difficult to teach; it is more than simply knowing the representations (e.g., graphs, words, equations and diagrams). For meaningful science learning to take place, consideration needs to be given to explicitly integrating representations into instructional methods, linked to the content, and…

Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

Visualizing physical concepts through models is an essential method in many sciences. While students are mostly proficient in handling mathematical aspects of problems, they frequently lack the ability to visualize and interpret abstract physical concepts in a meaningful way. In this paper, initially the electric circuits and related concepts were…

Elementary, middle-level, and high school science teachers commonly find their students have misconceptions about heat and temperature. Unfortunately, student misconceptions are difficult to modify or change and can prevent students from learning the accurate scientific explanation. In order to improve our students' understanding of heat and…

We have developed a simple and direct method to fabricate paper-based microfluidic devices that can be used for a wide range of colorimetric assay applications. With these devices, assays can be performed within minutes to allow for quantitative colorimetric analysis by use of a widely accessible iPhone camera and an RGB color reader application…

The study was conducted to investigate the effectiveness of Predict-Explain-Observe-Explain (PEOE) approach to student's performance in chemistry. This study also determined the correlation of metacognition to student achievement. Specifically, it sought to find out: (1)if there is a significant difference between the pretest and posttest scores…
