We use analogies to provide introductory laboratory students intuition into measurement uncertainties. Using a battery-resistor circuit we discuss uncertainty concepts and derive expressions for uncertainty of the mean and sums of uncertainties. Finally, we draw attention to the fact that the interpretation of standard deviation as uncertainty…

There is considerable evidence that incidental vocabulary acquisition through reading accounts for a large portion of the growth in word knowledge for both first (L1) and second (L2) language acquirers. In this paper, we evaluate the Markov Estimate of Semantic Association (MESA) technique for detecting small, incremental gains in vocabulary…

Ah ha moments are often mentioned in education literature. These moments are suggested to be a powerful aspect of learning, yet limited research is present regarding this topic. Ah ha learning moments have also not been defined in the education literature, resulting in the likelihood that each educator and learner may have differing definitions.…

This dissertation explores why grammatical structures are better learned implicitly or explicitly by investigating differential object marking (DOM) in Spanish. To address the effectiveness of implicit versus explicit instruction in the classroom, the researcher focused on two of the main features that constrain DOM in Spanish: animacy and…

The intention of the present study was to see the improvement of students' intuitive skills. This improvement was seen by comparing the Realistic Mathematics Education (RME)-based instruction with the conventional mathematics instruction. The subject of this study was 164 fifth graders of elementary school in Palembang. The design of this study…

Learning physics often requires overcoming common misconceptions based on naïve interpretations of observations in the everyday world. One proposed way to help learners build appropriate physics intuitions is to expose them to computer simulations in which motion is based on Newtonian principles. In addition, playing video games that require…

In recent years English newspapers have started featuring a number of puzzles other than the ubiquitous crossword. Many of the puzzles are of Japanese origin such as Sudoku, Kakuro or Hidato. However, one recent one is very English and is called variously Cross-code, Alphapuzzle or some other name. In this article, it will be known as Codeword.…

A number of studies have suggested the possible benefits of using concordancers in English as a Foreign Language (EFL) writing. To date, however, there is still limited understanding of how EFL writers may make use of such tools along with dictionaries when engaging in a writing task. To better understand the question, this study investigated a…

Presents a technique for introducing analysis of variance (ANOVA) at the concrete level of operational thought, enabling students in introductory statistics courses to understand the complex correlations and interactions between variables. Helps students develop an intuitive understanding of the concepts of between- and within-groups variance and…
