Are STEM Students Creative Thinkers?

Scholarly research has increasingly examined the role of STEM (Science, Technology, Engineering, and Mathematics) education, and that of creativity as a transversal skill. However, far fewer studies have investigated the relationship between the two, particularly in secondary-school contexts, and they have obtained inconsistent results. This paper contributes to the literature by asking: To what extent is studying STEM associated with higher levels of creativity in a secondary-school context? The study utilises a pre-existing dataset gathered in Malta (EU) from some 400 students aged between 11 and 16 years old. It yields information on both the engagement in STEM (measured by exposure to STEM chosen by students as optional subjects, and the enjoyment of STEM considered by students to be their favourite subjects), as well as creativity levels (measured by Divergent Thinking performance on Alternate Uses Tests). Correlation analysis revealed a strong positive link between the two phenomena, lending support to the notion that STEM students tend to be more creative than other students. Using regression analysis, a model is estimated to identify the possible effects of engaging in STEM subjects on creativity, once the other co-determinants of creativity are controlled. The results indicate that both the exposure to STEM subject/s and enjoyment thereof significantly and positively predict creativity, even after controlling for the other possible determinants of creativity (such as age, gender, parental education, and participation in creative activities). These findings offer encouraging insights into 21st century education and for curriculum development as they suggest that, in addition to having value in their own right, STEM subjects can contribute to the development of creativity in young people.

Young Creators: Perceptions of Creativity by Primary School Students in Malta

Policymakers and employers insist that educational institutions prepare workforce-ready candidates fluent in the application of 21st Century Skills such as creativity. So far, only a few studies have explored the self-perceived creativity of students. This paper addresses this gap in literature by providing an understanding of how young students in upper primary feel about themselves as creative beings. Data for the present study was collected through an anonymous online survey that 561 students, aged 9–11 years and residing in Malta (EU), completed. In-depth responses were collected from a subset of the original sample made up of 101 students through an anonymous online form containing a set of questions. Data was analysed using regression analysis for the quantitative component and through thematic analysis for the qualitative part. Results indicate that, overall, students in Year 6 felt less creative than students in Year 5. Furthermore, findings show that the type of school attended impacted the students’ perception of creativity. From a qualitative perspective, findings led to insights into (i) the interpretation of the term creativity and (ii) the impact of the school environment and how timetabling impacted students’ creativity. The findings suggest that the student’s perceived creative personal identity and the concrete manifestations that they engage in are influenced by environmental factors.

Visceral leishmaniasis in Malta--an 18 year paediatric, population based study

BACKGROUND

Visceral leishmaniasis (VL) is a chronic parasitic infection that infects approximately 400,000 individuals annually, with a predilection towards early childhood.

AIMS

To study the epidemiology of VL in childhood.

METHODS

VL is endemic in Malta, a small archipelago of islands in the centre of the Mediterranean with a total population approaching half a million. Notification of human cases of leishmaniasis is compulsory. Case records of all 81 paediatric patients with VL between 1980 and 1998 were analysed.

RESULTS

The annual incidence of VL declined for all cases of VL, and declined significantly for paediatric cases (p = 0.01). For 1994 to 1998, the overall incidence of VL was 0.9 per 100,000 total population and the paediatric incidence was 2.5 per 100,000 population. Median age at presentation was 34 months. Common features at presentation were splenomegaly, hepatomegaly, fever, and pancytopenia with high lymphocyte and monocyte counts. The diagnostic sensitivity of isolated immunofluorescent antibody testing was equivalent to bone marrow aspiration (95%). Blood transfusions for anaemia were required in 93% of patients. Eleven per cent had intercurrent infections. All patients were cured, and were initially treated with intravenous sodium stibogluconate. Defervescence occurred after a median of six days of treatment, and patients continued to be treated on a day case basis. Nine relapsers were retreated with sodium stibogluconate, achieving a cure rate of 94%, but five patients required additional drug therapy. There were no permanent sequelae associated with VL or its treatment.

CONCLUSIONS

The decreased incidence is attributed to the eradication of stray dogs which are the disease reservoir.

Resolution, absolute configuration, and antiarrhythmic properties of the enantiomers of disopyramide, 4-(diisopropylamino)-2-(2-pyridyl)-2-phenylbutyramide

Disopyramide was resolved by fractional crystallization of its diastereomeric bitartrate salts from methanol-acetone. Diastereomeric sulfonamides prepared from (+)-camphor-10-sulfonyl chloride and the primary amines obtained by LiAlH4 reduction of the resolved bases were separable by high-performance LC and were used to show that within experimental error resolution of disopyramide was complete. The absolute configuration was determined by X-ray crystallography. (+)-[(2R)-(-)-4-(Diisopropylamino)-2-(2-pyridyl)-2-phenylbutyramide (+)-(2R,3R)-bitartrate] crystallizes in space group P212121: a = 14.789 (4), b = 18.151 (4), c = 9.878 (2) A; Z = 4: Dx = 1.225, Dm (flotation C6H6/CCl4) = 1.226 g cm-3. The structure was solved by direct methods. The enantiomeric bitartrates were tested for antiarrhythmic properties. The enantiomeric bitartrate salts were equally effective in prolonging the effective refractory period (ERP) of rabbit ventricle. At 3 x 10(-6) M, the (-)-bitartrate [from (2S)-(+)-disopyramide] increased the ERP 21.8 +/- 6.3 ms and the (+)-bitartrate [from (2R)-(-)-disopyramide] increased the ERP 25.8 +/- 3.6 ms. At 1.5 x 10(-5) M no significant difference was noted, as the increases in the ERP were 41.2 +/- 8.9 and 50.5 +/- 6.3 ms for the (-)- and %+)-bitartrate, respectively.
