This article presents a corpus-based investigation on English prepositions of time presented in the argumentative essays of Form 4 and Form 5 Malaysian secondary students in the MCSAW corpus. The aims were to find out the distribution patterns and the common errors in the use of preposition of time, "on" and "at". This corpus…

A study was conducted to examine the persistence and decay of web citations in theses and dissertations available at the Sokoine National Agricultural Library. Specifically, the study assessed the accessibility status of cited URLs, identified error messages and top level domains of inaccessible URLs, and calculated the half-life of web citations.…

A recent international study of pre-service teachers identified that proportional reasoning was problematic for pre-service teachers. Proportional reasoning is an important topic in the middle years of schooling and therefore it is critical that teachers understand this topic and can rely on their Mathematical Content Knowledge (MCK) when…

Background: Children with speech sound disorders (SSD) form a heterogeneous group who differ in terms of the severity of their condition, underlying cause, speech errors, involvement of other aspects of the linguistic system and treatment response. To date there is no universal and agreed-upon classification system. Instead, a number of…

A single subject study with multiple baselines across participants was used to explore the effect of giving access to picture-to-text software for writing to young students, with moderate autism, and documented difficulties with written language. For this intervention study, three participants, who had strengths in visual processing and who were…

The goal of this study was to determine potential causes for the reading and spelling discrepancies of 26 middle school students. All were proficient in reading, but non-proficient in spelling, a pattern typical in students with Specific Spelling Disability (SSD). The focus of the study was on linguistic knowledge while encoding and decoding, plus…

This is a descriptive research on the difficulties of Filipino high school students in translating algebraic word problems into mathematical equations. This research is composed of three parts: (1) development of an 11-page "Filipinized" questionnaire; (2) analysis of the mathematical thinking processes of the respondents based on the answers to…

As a result of growing attention in cross-cultural research, existing measurement instruments developed in one language are being translated and adapted for use in other languages and cultural contexts. Producing invariant measurement instruments that assess educational and psychological constructs provide a way of testing the cross-cultural…

Reading is an active process where readers sometimes have difficulty understanding what they read. Ultimately, readers are required to combine the meaning of each sentence in a text in order to achieve text-level comprehension. Otherwise, the reader is going to have great difficulty with text-level comprehension. Factors such as sentence length…

Repetition blindness (RB) is the finding that observers often miss the repetition of an item within a rapid stream of words or objects. Recent studies have shown that RB for objects is largely unaffected by variations in viewpoint between the repeated items. In 5 experiments, we tested RB under different axes of rotation, with different types of…

The goal of this study was to understand errors that student make when simplifying exponential expressions. College students enrolled in four college mathematics courses were asked to simplify and compare such expressions. Quantitative analysis identified three persistent errors: interpreting negative bases, negative exponents, and parentheses.…

Many studies have pointed to impaired speech intelligibility in young people with Down's syndrome (DS). Some have attributed these problems to delayed phonological development, while others have identified disordered speech patterns, which could be related to a dyspraxic element in their speech. This study uses electropalatography (EPG) to examine…

This paper reports use of sample stimulus control shaping procedures to teach arbitrary matching-to-sample to 2 capuchin monkeys ("Cebus apella"). The procedures started with identity matching-to-sample. During shaping, stimulus features of the sample were altered gradually, rendering samples and comparisons increasingly physically dissimilar. The…

The lexical decision task is probably the most common laboratory visual word identification task together with the naming task. In the usual setup, participants need to press the "yes" button when the stimulus is a word and the "no" button when the stimulus is not a word. A number of studies have employed this task with developing readers;…

Previous studies on performance monitoring repeatedly found attenuated error-related negativities (Ne/ERN) in elderly, while findings for the correct-related negativity (Nc/CRN) are inconsistent. The present study aimed at clarifying inconsistent Nc/CRN results in elderly. Therefore, a refined design was employed to control for potential…
