The Impact

Background: Interactive Teaching learning can be used in clinical subjects like surgery for better participation of students as one-way didactic lectures do not involve active participation of students. WhatsApp is one of the most famous messaging services which everyone use and it is easy, cheaper, and faster. Objective: the purpose of the study was to study the impact of whatsapp in improving learning in general surgery among 9th semester medical students. Methods: This study was conducted among 9th semester MBBS students in Surgery department. Students were divided into group a (study group) and group b(control group) by a simple random sampling. Gastric cancer was discussed among students of both Groups through didactic teaching. after didactic teaching, only Group A students were exposed to social media type of learning, i.e., using WhatsApp, after the session a multiple-choice questionnaire having 10 MCQs was given to both groups and an additional poll was conducted among the Study-group students to assess their perception towards Whatsapp intervention. the mean score obtained by both the groups were compared with unpaired t test. P-value <0.05 is taken as statistically significant. Results: The mean (SD) score of the Study-group was 8.58(1.18) and the mean (SD) score of the Control-group was 5.41(1.32) and statistically significant difference was found between the two groups scores with a p-value less than 0.05 opinion poll found that the intervention of whatsapp among study group was effective. Conclusion: we observed that the usage of WhatsApp in addition to the didactic teaching was found advantageous and enhanced learning in undergraduate students

Recent advances in microcomputer technology have made it possible to simulate realistic classroom situations, thereby allowing preservice teachers to learn and practice a wide variety of fundamental instructional and management skills under controlled conditions. This study was undertaken to provide further evidence of the effectiveness of the misbehavior component of the Curry Simulation in training preservice teachers to use research-based classroom management techniques. Participating in two consecutive 10- to 20-minute simulation sessions in which they presented a spelling lesson to a group of software-defined “pupils” were 18 undergraduate students of regular and special education. Each subject received one or two types of information about classroom management between simulation sessions. Analyses of performance data revealed that the mean number of appropriate management responses made to computer-generated pupil talkouts increased significantly across simulation sessions while the mean number of inappropriate responses decreased significantly. The amount of time spent dealing with pupil misbehavior was also significantly reduced. Furthermore, effects were maintained at a 2- to 8-week follow-up session. No significant effects were found for type of management information provided to subjects between sessions or for selected subject variables. Limitations of the study and implications for program development are discussed.

BACKGROUND Internet addiction problem is becoming a significant public health concern nowadays, especially during Covid-19 pandemic. Internet Addiction Test (IAT) is one of the most popular questionnaires for evaluating the internet addiction level. Using the same questionnaire in the similar population, the prevalence of IA was ranging from 28.3% to 66.6% with possibly due to the Likert scale used. Different methods on treating “not applicable” option in the Likert scale used in IAT questionnaire might increase the variability in results, and this might not be aware especially when comparing the results among studies. OBJECTIVE This paper aims to compare the differences of results in terms of total scores and prevalence of IA on using four different methods on dealing with the “not applicable” option on the IAT questionnaire. METHODS A total of 417 undergraduate students were recruited from a public university in Malaysia to fill in the IAT questionnaire with six Likert scale that include the following options from “not applicable”, “rarely”, “occasionally”, “frequently”, “often” and “always”. The total score and prevalence of IA for four different methods (Method 1, Method 2, Method 3 and Method 4) on treating “not applicable” option were be compared. RESULTS Out of 20 questions in IAT questionnaire, there were 11 questions had more than 80% of answer rate but no question with 100% answer rate. Only 17.5% of respondents answered all the questions. The Cronbach alpha test showed that four methods had good reliability value (0.910-0.945). The mean ± standard deviation of total scores of IA for Method 1, Method 2, Method 3 and Method 4 were significantly different, with 49.15±15.60, 40.50±17.50, 44.31±15.11 and 48.15±15.08 respectively (P<0.001). Method 1 had significant highest prevalence of IA (43.4%), followed with Method 4 (40.0%), Method 2 (28.3%) and Method 3 (17.3%) (P<0.001). CONCLUSIONS Four methods on treating the “not applicable” option in the IAT questionnaire showed significant different results, with Method 1 showed significant highest mean total score and prevalence of IA compared to other methods. Researchers are advised to choose an appropriate method on treating the “not applicable” questions, and also be aware of this when comparing the results among different studies.

Sum Scores

Researchers examined the mean sum scores of 15 semantic differential scales to specify the evaluative index assigned to the term condom by 173 undergraduate students at a large public university. Of interest was whether evaluative indices were different for men and women, and for condom ever-users versus never-users. There was no sex difference in semantic evaluation of condom. However, the mean sum score of persons with prior condom experience reflected a significantly more positive rating compared to persons who were never-users. Because use of condoms is associated with an evaluative index that is statistically more favorable, encouraging sexually active young adults to try condoms may promote consistency of use, and thereby reduce undesired pregnancies and sexually transmitted infections.

Researchers in fields outside of special education have found that concept maps reveal changes in student cognitions as a result of course enrollments and clinical experiences. Hence, we used concept maps to trace conceptual change in preservice teachers enrolled in an introductory multicultural/special education course at Michigan State University (MSU). We analyzed pre- and post-concept maps, explanatory paragraphs, and comparative essays of 30 randomly selected undergraduate students enrolled in the course. Results revealed significant quantitative and qualitative differences between pre- and post-measures. We present these results in detail and outline implications for research and teaching in the area of multicultural teacher education in special education.

Abstract Background It is shown that meeting the increased nutritional demand of preterm infants from birth is not only important for survival but essentially contributes to the infants` overall development and long-term health. While there are established guidelines for weaning term infants, evidence regarding preterm infants is scarce and less precise. The aim of this study was to identify the current practices on introducing solids to preterm infants amongst caregivers in Salzburg and determine potential reasons for early weaning. Methods Altogether 68 infants born between 24 0/7 and 36 6/7 weeks were recruited and detailed structured interviews with the caregivers were conducted at 17 weeks corrected age. Weight, height and head circumference were collected. Results 52% of the study group received solids before the recommended 17 weeks corrected age. For this group the mean age being 13.77 ± 1.11 weeks corrected age. Premature introduction of solids significantly correlates with exclusively and early formula-feeding. 34% were weaned due to recommendation by their paediatrician. 23% of the preterm infants even received solids before 12 weeks corrected age, putting them at risks for developing obesity, celiac disease and diabetes. Conclusions This study shows the necessity for clear guidelines regarding the introduction of complementary feeding in preterm infants as well as the importance of their implementation. Caregivers should receive information on this topic early enough and they should fully understand the difference between chronological and corrected age.
