This research aimed to examine the impact of using mobile-supported learning management systems (LMS) in teaching web design on the academic success of students and their opinion on the course; and it was conducted on 70 volunteer students (35 experimental, 35 control) enrolled at Giresun University, Technical Sciences Vocational School, Computer Technologies Department, Program of Computer Programming in Spring 2015–2016. After the eight weeks long implementation of Mobile Moodle, which is a mobile-supported LMS, as a supplement to traditional learning methods; t-test was used in order to determine whether the methodology mentioned had a significant impact on the academic success of web design teaching. As a result of the t-test implemented; it was seen that there was a significant level of difference in favor of the experimental group; between the academic success of students in the experimental group where mobile-supported LMS is used and the academic success of the students in the control group where traditional learning methodologies are used. Also, it has been determined that using Mobile LMS has increased the students’ interest. 相似文献

This paper reports on the use of a constructivist-based pedagogy to enhance understanding of some features of solution chemistry.
Pre-service science teacher trainees' prior knowledge about the dissolution of salts and sugar in water were elicited by the
use of a simple diagnostic tool. The test revealed widespread alternative conceptions. These evaluation data were used to
produce two segments of ‘conceptual change text’: concise summaries that present alternative and scientific conceptualizations
for the concepts under study. The texts were administered to 21 pre-service elementary trainee teachers whose understandings
of number of conceptions were subsequently re-evaluated employing a pre-test post-test approach in which their answers and
reasons for their answers were solicited. The findings suggest that these pre-service elementary trainees' alternative conceptions
are changed to become more in accord with the scientific view, with more participants providing correct answers along with
correct reasons than before the intervention. This work suggests that the use of conceptual change text may provide a simple
and cost and resource-effective way to aid conceptual understanding for the dissolution of ionic solids in water including
the effect of solute surface on the dissolution process. 相似文献

Hemodynamically significant ductus arteriosus (hsPDA) may alter organ perfusion by interfering blood flow to the tissues. Therefore, in infants with hsPDA, hypoxia occurs in many tissues. In this study, we aimed to investigate the diagnostic significance of serum (ischemia-modified albumin) IMA levels as a screening tool for hsPDA, and its relation to the severity of the disease in the preterm neonates. For this purpose, seventy-two premature infants with gestation age <34 weeks were included in the study. Thirty premature infants with hsPDA were assigned as the study group and 42 premature infants without PDA were determined as the control group. Blood samples were collected before the treatment and 24 h after the treatment, and analyzed for IMA levels. IMA levels in the study group (1.26 ± 0.36 ABSU) were found to be significantly higher than control group (0.65 ± 0.12 ABSU) (p < 0.05). In infants with hsPDA, a positive correlation was found between IMA and PDA diameter (ρ = 0.876, p = 0.022), and LA/Ao ratio (ρ = 0.863, p = 0.014). The cut-off value of IMA for hsPDA was measured as 0.78 ABSU with 88.89 % sensitivity, and 90.24 % specificity, 85.71 % positive predictive, 92.5 % negative predictive value [area under the curve (AUC) = 0.96; p < 0.001]. The mean IMA value of the infants with hsPDA before treatment was 1.26 ± 0.36 ABSU, and the mean IMA value of infants after medical treatment was 0.67 ± 0.27 ABSU (p = 0.03). We concluded that IMA can be used as a marker for the diagnosis and monitoring of a successful treatment of hsPDA. 相似文献

Taking a test generally improves the retention of the material tested. This is a phenomenon commonly referred to as testing effect. The present research investigated whether two-tier diagnostic tests promoted student teachers’ conceptual understanding of variables in conducting scientific experiments, which is a scientific process skill. In this study, 97 preservice science teachers were divided into three groups. All three groups took a physics laboratory course during the fall term in which they learned about variables in the course. Each group was engaged in a different learning activity after the physics laboratory course: taking a two-tier diagnostic test, taking a multiple choice test, or studying a lecture summary. The narratives of the participants before and after the learning activities were transcribed into a format of flow maps to assess their conceptual understanding of variables. The results revealed that the two-tier diagnostic test is an effective tool in promoting conceptual understanding of complex concepts about variables in conducting scientific experiments. 相似文献
