Hand Anomalies

Background and Aims: Impact of appearance of congenital hand anomalies has not previously been reported. The purpose of this study was to describe the common perception about how different congenitally malformed hands look. Material and Methods: We developed a questionnaire in a game format to evaluate the appearance of different hands. Altogether 1450 (954 females) 4- to 84-year-old residents (296 children) of two European and one Asian (n = 102) country were asked to rate the appearance of different looking hands on a five-point pictorial Likert-type scale. Standardized photographs of the dorsal aspect of 17 different congenitally malformed non-operated hands and a normal hand were presented to respondents. Significance of age, gender, nationality, and profession of the respondents was assessed. Results: The respondents’ ranking order of the hands was nearly consistent. The normal hand (mean = 4.43, standard deviation = 0.85, Md = 5) and clinodactyly (mean = 4.37, standard deviation = 0.86, Md = 5) were perceived to have the best appearance. Symbrachydactyly (mean = 1.42, standard deviation = 0.68, Md = 1) and radial club hand (mean = 1.40, standard deviation = 0.68, Md = 1) received the lowest scores. Adults rated the appearance of hands higher than children regarding 14 hands, females higher than men regarding 15 hands, and Europeans higher than Asians in 4 hands (p < 0.05, respectively). Europeans rated four-finger hand (mean = 3.21, standard deviation = 1.18, Md = 3) better looking than six-finger hand (mean = 2.92, standard deviation = 1.18, Md = 3, p < 0.005), whereas Asians gave higher scores to six-finger hand (mean = 2.66, standard deviation = 1.26, Md = 3) compared to four-finger hand (mean = 2.51, standard deviation = 1.14, Md = 2). Medical doctors and nurses gave higher scores compared to the other profession groups, school children, and high school students in five hands (p < 0.05). Conclusion: A normal hand is perceived distinctly better looking than most congenitally different hands. Different malformations’ appearance was ranked very coherently in the same order despite of participants’ age, gender, nationality, or profession. Asians seem to prefer an additional digit to a four-finger hand.

Model Set

Abstract Structure model sets for inorganic compounds are generally expensive; their distribution to all students in a class is therefore usually impractical. We have therefore developed a structure model set to illustrate inorganic compounds. The set is constructed with inexpensive materials: ping-pong balls, and snap buttons. The structure model set can be used to illustrate isomerism in coordination compounds and periodic structures of ceramic perovskites. A hands-on activity using the structure model set was developed for high school students and was well-received by them. Despite the concepts being slightly advanced for them, the students’ retention of the knowledge gained through the activity was tested a week after they completed the activity and was found to be relatively high, demonstrating the usefulness of the activity based on the structure model set.

Students often struggle to connect concepts with evidence, sometimes because development of research skills has not been emphasized in their science courses. We developed a strategy and protocol to train high school students in research and experimental investigation of questions related to course material on legume biology. The richness of this subject matter allows for adaptations of our framework to address diverse areas of science, including principles in ecology, environmental science, agriculture, microbiology, and evolution. Our framework includes a hands-on classroom inquiry that investigates the symbiotic relationship between nitrogen-fixing rhizobial bacteria and legumes. This student-led, inquiry-based project employs an intellectually demanding, hands-on method of education to build critical research skills using an adaptable model and inexpensive materials. We also report positive student feedback from a post hoc survey to gauge student attitudes toward the activity and the effectiveness of this framework.

Abstract The aim of this study was to determine sustainable learning levels of students. The study also attempted to determine sustainable learning levels of students based on gender and grade. The participants of the study consisted of 742 high school students (354 females and 388 males) in various high schools in Babaeski district of Kırklareli, Turkey during the 2017–2018 academic year. In order to collect data, a scale with two subscales – behavioural and cognitive – was developed. The data were analysed through SPSS 17, and arithmetic mean, standard deviation, t-test and one-way analysis of variance (One Way Anova) were used. According to the results of the study, it is concluded that sustainable learning level of the high school students is moderate. The study also found a significant variation in favour of the female students in “learning for development” subdimension on the cognitive subscale of the scale.

<p><em>This study investigates whether teaching spelling to high school students using different techniques, i.e. copy, cover, compare and flip folder, would improve students’ spelling. Additionally, it explores students’ opinions and perceptions towards these techniques. The research conducted in Granada high school in Makkah, Saudi Arabia. Thirty-six male students participated in this study whose levels according to the course book were assumed to be B1 in the Common European Framework of Reference for Languages (CEFR). In this study, a mixed research method was used where data was analyzed quantitatively and qualitatively. The first group was taught using copy cover and compare method (CCC), which emphasizes repeated practice when errors occur in students spelling, whereas the second group was trained using the flip folder technique which is a combination of visual, auditory, and kinesthetic techniques that were believed to enhance memorization. A post-test was utilized immediately after the intervention and the results showed that the CCC group outperformed the Flip Folder group. </em></p>

Background: The school community's readiness to face disasters is still considered lacking in Indonesia. Schools as educational institutions are expected to provide an important role for disaster risk education, so students have the provision in dealing with disasters.Objective: This study aimed to identify the factors associated with the preparedness of high school students in dealing with the earthquake and tsunami disasters.Method: This study is analytic survey with cross sectional design. The population in this study were all high school students in Bengkulu City in 2018/2019 academic year. Two stages cluster sampling method have been used in this study. The researcher randomly chooses one high school that will be used as a research location, SMAN 2 Bengkulu City were selected as the result, then the researcher randomly chooses again to determine which class will be the sample, class of XI was chosen with a total of 340 students who spread across 11 classes. The researchers calculated the sample size by using the Slovin formula with the results of 220 respondents. The samples were selected by using proportional random sampling technique, and chosen based on the number of students in each class. Data collection in this study used an instrument in the form of a questionnaire adopted from LIPI consists 65 questions about knowledge and 10 questions about disaster warning and 36 questions about preparedness. The collected data is then processed and analyzed using computer program software and the data were analyzed by using univariate, bivariate and multivariate logistic regression statistical testsResult: The results of this study showed that preparedness of 220 respondents were obtained a mean of 23.57 with a standard deviation of 7.844, knowledge were obtained a mean value of 46.69 with a standard deviation of 8.229, attitudes were obtained a mean value of 60.01 with a standard deviation of 6.210, an emergency response plan were obtained a mean value of 14.95 with a standard deviation of 3.050, and disaster warning were obtained a mean value of 7.19 with a standard deviation of 2.408. Factors related to student preparedness in dealing with disasters were included the level of knowledge (p = 0.020), attitude (p = 0.280), emergency response plan (p = 0.000), disaster warning (p = 0.000).Conclusion: There is a relationship between the level of knowledge, and disaster warnings with disaster preparedness. The most dominant factor in disaster preparedness is disaster warnings. Key words: Preparedness, knowledge, disaster warning.

Local Lotto is a 14-session curriculum designed for high school students to learn mathematics through an examination of the local lottery. The curriculum is organized around investigations of how local lottery games are won, who plays, how many people play, and where lottery revenues and prizes are distributed. A web-based application is integrated into the curriculum to allow students to explore the lottery in their school neighborhood, examine local lottery data, and assemble and justify their own arguments about the lottery. In this chapter, the authors describe technology's role in shaping a rich curriculum that engages students in investigating a local phenomenon while also addressing the content and practices of the Common Core State Standards of Mathematics. The chapter concludes with an outline of the challenges of integrating custom technologies into mathematics curricula and provides recommendations for future work.
