background: considering the assumptions of cognitive load theory and using its reduction and optimization strategies in the design and development of instructional content is one of the main requirements for achieving effective learning. this study examined the effectiveness of instructional multimedia based on reducing the extraneous cognitive load in english language learning among nursing st...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
In practice, bootstrap tests must use a finite number of bootstrap samples. This means that the outcome of the test will depend on the sequence of random numbers used to generate the bootstrap samples, and it necessarily results in some loss of power. We examine the extent of this power loss and propose a simple pretest procedure for choosing the number of bootstrap samples so as to minimize ex...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
The purpose of this research was to investigate the effectiveness of instruction of metacognitive knowledge on academic stress in high school female students. This research method is quasi experimental with pretest and post test. Given this, 37female first grade students (19 subjects in experimental group and 18 subjects in control group) were randomly selected using multi-stage cluster samplin...
Effect of an infection control programme in enteral feeding bacterial contamination in nursing homes
Methods It was a quasiexperimental pretest posttest control study. There were 15 residents and 10 nursing home staff in experimental and control groups respectively. An ICP related to enteral feeding was given to the experimental group. The knowledge and practice in enteral feeding among nursing home staff was measured by questionnaires; and 60 pairs of specimens were taken for bacterial counts...
We examine a corpus of physics tutorial dialogues between a computer tutor and students. Either graphs or illustrations were displayed during the dialogues. In this work, stepwise linear regression, augmented to remove unwanted terms, is used to build models that identify situations when each graphic may aid learning. Our experimental results show that grouping students by pretest score, then b...
BACKGROUND The individual risk of developing psychosis after being tested for clinical high-risk (CHR) criteria (posttest risk of psychosis) depends on the underlying risk of the disease of the population from which the person is selected (pretest risk of psychosis), and thus on recruitment strategies. Yet, the impact of recruitment strategies on pretest risk of psychosis is unknown. METHODS ...
The main focus of this informative article is to bring attention to experimental research in the field of information systems, especially for novice researchers such as doctoral students. In the past three decades, information systems research has been heavily focused on theoretical model development and testing using survey-based methodology. However, criticism on such an approach has been pre...
