Computer Science (CS) courses comprise both Programming and Information and Communication Technology (ICT) issues; however these two areas have substantial differences, inter alia the attitudes and beliefs of the students regarding the intended learning content. In this research, factors from the Social Cognitive Theory and Unified Theory of…

This study examined impediments to research among students of institutions of higher learning in Nigeria. The study was guided by one research question and three hypotheses. Data were collected from 600 final year students randomly selected from institutions of higher learning in Nigeria. Data were analyzed using descriptive statistics of mean to…

A cross-age peer tutoring program was implemented in a small rural school in west central Belize, Central America. All students at the school were native Spanish speakers, and all general instruction was conducted in English. The program was devised to supplement existing reading and language arts instruction at all grade levels. Progress of both…

Newer statistical procedures are typically introduced to help address the limitations of those already in practice or to deal with emerging research needs. Quantile regression (QR) is introduced in this paper as a relatively new methodology, which is intended to overcome some of the limitations of least squares mean regression (LMR). QR is more…

Much of the recent research on homework focuses on using online, web-based, or computerized homework systems. These systems have many reported capabilities and benefits, including the ability to randomize values, which enables multiple attempts by a student or to reduce academic dishonesty. This study reports on the impact of using randomized…

The study attempted to determine if there is a relationship between user's psychological personality types, measured by the Myers Briggs Type Indicator[R] (MBTI[R]) and distinct measures of usability measured by the Software Usability Measurement Inventory (SUMI). The study was expected to provide an answer to the following basic research…

Contrary to the advice of supposedly authoritative sources, the a priori exclusion of supernatural explanations or claims from scientific scrutiny is not appropriate. This paper shows how supernatural hypotheses or claims should be treated by science and, in the process, differentiates scientific and non-scientific hypotheses or claims.…

Several models assume that working memory development depends on age-related increases in efficiency and speed of processing. However, age-related increases in the efficiency of the mechanisms that counteract forgetting and restore memory traces may also be important. This hypothesis was tested in three experiments by manipulating both the…

Aim: To compare the effects of a supported speed treadmill training exercise program (SSTTEP) with exercise on spasticity, strength, motor control, gait spatiotemporal parameters, gross motor skills, and physical function. Method: Twenty-six children (14 males, 12 females; mean age 9y 6mo, SD 2y 2mo) with spastic cerebral palsy (CP; diplegia, n =…

Aim: Information on the timing and long-term outcome of single-event multilevel surgery in children with bilateral spastic cerebral palsy (CP) walking with flexed knee gait is limited. Based on our clinical experience, we hypothesized that older children with bilateral spastic CP would benefit more from single-event multilevel surgery than younger…

This study examined the interrelationships among mattering to friends, self-esteem, spirituality, and perpetration of relational aggression in friendships among 457 college students. While the three self-belief variables were positively related to each other, only spirituality and mattering to friends discriminated between men and women. Women…

Problem-based learning (PBL) is generally organized in three phases, involving collaborative and self-directed learning processes. The hypothesis tested here is whether learning in the different phases of PBL is cumulative, with learning in each phase depending on that of the previous phase. The scientific concepts recalled by 218 students at the…

Eighty-seven parents and primary caregivers of children aged 10 years or younger participated in a study examining the effects of the ACT Raising Safe Kids program on children's behavior. It was hypothesized that children of caregivers who complete ACT-RSK would demonstrate reduced behavior problems compared to children of caregivers in a…

Null hypothesis testing (NHT) is the most commonly used tool in empirical psychological research even though it has several known limitations. It is argued that since the hypotheses evaluated with NHT do not reflect the research-question or theory of the researchers, conclusions from NHT must be formulated with great modesty, that is, they cannot…

The genome projects of the past decades have created extensive databases of biological information with applications in both research and education. We describe an inquiry-based exercise that uses one such database, the National Center for Biotechnology Information Influenza Virus Resource, to advance learning about influenza. This database…
