Measuring attitude towards learning science in Malaysian secondary school context: implications for teaching

ABSTRACT

The aim of education is to ensure a holistic development towards knowledge and well-being. Despite exhaustive effort on embedding twenty-first century skills in science teaching, students show lack of interest to learn and pursue their science careers. This present study has attempted to develop an instrument for measuring attitude towards science learning. The purpose was to ensure valid items were identified to measure all aspects of attitude namely affect, behaviour and cognitive. The study of attitude in science will determine the direction on how teaching strategies can be successful in promoting interest in learning. The study has been underpinned from the theories related to Theory of Reasoned Action, Constructivist learning and Connectivism. Samples from three secondary schools were selected based on proportionate stratified random sampling. 350 samples were targeted to respond to self-constructed questionnaires. Confirmatory Factor Analysis (CFA) was employed to prove the hypothesised 5-factor measurement model. The results have supported a model fit with positive interactions between the factors are evident. The study has proven the theoretical contributions which embark on holistic development of an individual to ensure attitude is moulded. The emotional and spiritual aspects of learning are needed to ensure positive contribution to the social dynamic. In this paper, the discussions are elaborated from the standpoints of theories and practical importance. The results have contributed to a theoretical model of science teaching method.     

Entrepreneurship education in Malaysian universities

Entrepreneurship education in the strongly emerging market of Malaysia was examined throughout the country’s 20 public universities. A broad based interview process amongst multiple stakeholders profiled educational policies as well as revealing shortcomings in practice. Observers noted that students showed a preference for salaried jobs after graduation rather than setting up their own businesses, despite participation in entrepreneurship classes and programmes. Policymakers indicated that curricula had deficiencies despite their hype. Passive lectures were far more common than more interactive methods. It is suggested that if Malaysian universities are to promote entrepreneurship education in an effective way, they must address these issues.

     

Analysis of Intrinsic and Extrinsic Coagulation Pathway Factors in OCP Treated PCOS Women

Human polycystic ovary syndrome (PCOS)—a cluster of diseases displays various symptoms associated with endocrine and gynecological disorders in childbearing women. Oral contraceptive pills (OCP) being a drug of choice minimizes symptoms and complications associated with the disorder. But, the controversial data available in literature regarding use of OCPs compels us to setup a study design regarding effect of OCP treatment in PCOS subjects and the possible outcomes specifically regarding coagulation pathways. Two PCOS study groups have been selected according to Rotterdam Criteria: one with OCP treatment (n = 50) and other without any drug treatment i.e., drug naive (n = 50). Anthropometry, Biochemistry, Hormones, Insulin and various clotting factors like Factor XI, Factor V, tPA, TAT-III and D-dimer were analyzed in both groups. The results showed worsening of IR, Metabolic parameters and coagulopathy in OCP group comparative to drug naive group indicating adverse effects of the OCP treatment which puts these women at risk for number of future clinical implications especially Cardiovascular and metabolic complications.     

Interconversion of Fischer and zig-zag projections learning stereochemistry with the help of hands

Visualization of molecules in three dimensions is an important aspect of organic chemistry. The use of hands has been shown to be effective in the three-dimensional visualization of molecules [1]. A method of looking at one’s own hands as a model that allows students to see the interconversion of Fischer and zig-zag projections is described in this article.     

INSTRUCTIONAL ACTIVITIES AND GROUP WORK IN THE US INCLUSIVE HIGH SCHOOL CO-TAUGHT SCIENCE CLASS

In the US, there is a significant number of learning-disabled high school students included in regular science classrooms. It has been argued that students with learning disabilities can succeed in science if they receive the kind of instruction they need. To facilitate such instruction, the special education teacher is often incorporated into the class along with the learning disabled students. We observed 53 high school science lessons from ten pairs of science and special-education teachers who were responsible for delivering instruction to groups of students, some of whom were learning-disabled. We analyzed narrative notes collected in these lessons reflecting the kinds of classroom activities, organization of work, and teachers’ roles. In addition, we interviewed the teachers individually to gain a better understanding of these inclusive classes. The underlying question of this research was whether inclusive classes with two teachers delivered the type of science education that is better than solo-teaching in addressing the needs of learning-disabled students. Our evidence indicates that even with a special-education teacher present in the class, learning-disabled students usually did not receive a science education that met their needs. We elaborate on the reasons for this problem and make suggestions for improvement.     

We are invited to imagine: using a literary text to encourage cross-cultural dialogue about citizenship

ABSTRACT

Using William Golding’s Lord of the Flies as a stimulus, researchers from Norway, Pakistan and the United Kingdom explored the potential of a literary text to encourage intercultural dialogue. The innovative research method used was to combine Literature Circles and Google Documents to provide a platform for asynchronous online exchange between three cohorts of students in higher education. The authors’ analysis of the data suggested differences between those students who regarded the text as a living document speaking directly to their personal experiences of citizenship issues and those for whom the novel remained a historical document, removed from their lived experience. The authors contend that this research can contribute original and significant insights to the literature on teaching citizenship through literary texts such as the relationship between text choice and context, models of international collaboration at the higher education level and contrasting approaches towards citizenship and reading.

Phytochemical composition,biological potential and enzyme inhibition activity of <Emphasis Type="Italic">Scandix pecten-veneris</Emphasis> L.

Objective

Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.

Methods

Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.

Results

S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.

Conclusions

Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.

     

Detection of hemoglobin E in Endhra Pradesh: Mutational analysis using polymerase chain reaction and restriction enzyme Mnl 1

Hemoglobin E (beta-26^{Glutamic acid→Lysine}) is the second most prevalent hemoglobin variant in the world. 293 blood samples from cases referred from several hospitals in the region of Andhra Pradesh were screened for the detection of hemoglobinopathies. Four samples were found to be in heterozygous state for Hb E condition. Mutation in two of these heterozygotes was analysed using a 722 base pair (bp) amplified DNA fragment from beta-globin gene and restriction enzyme Mnl 1. A 232bp DNA fragment was found to be associated with the Hb E mutation.     

hs-CRP: A potential marker for hypertension in Kashmiri population

Hypertension is the most important public health problem in developing countries and one of the major risk factors for cardiovascular diseases, and it has been reported that hypertension is in part an inflammatory disorder and several workers have reported elevated levels of CRP in hypertensive individuals. The main aim of the present study was to evaluate the association between blood pressure and serum CRP levels across the range of blood pressure categories including prehypertension. A total of 104 patients and 63 control subjects were included in the present study. The level of CRP in the serum samples was estimated by a high sensitivity immunoturbidometric assay. Standard unpaired student’s ‘t’ test was used for comparison of hs-CRP levels between hypertensive patients and normotensive control subjects and between patient groups with different grades of hypertension and different durations of hypertensive histories. The mean serum hs-CRP level in hypertensive patients was 3.26 mg/L compared with 1.36 mg/L among normotensive control subjects (P<0.001). On comparison with normotensive control subjects, the hs-CRP levels vary significantly both with grades and duration of hypertension, with most significant difference found in patients with prehypertension (P<0.001), followed by Stage-I (P=0.01) and Stage-II(P=0.02) hypertensives. Significant difference in hs-CRP levels was also found in patients with shorter duration of hypertensive history (≤ 1year) when compared with those with ≥5 years of hypertensive history (P<0.01). Our study reveals a graded association between blood pressure and CRP elevation in people with hypertension. Individuals with prehypertension or with shorter duration of hypertension (≤1 Year) had significantly a greater likelihood of CRP elevation in comparison to chronic stage-I or stage-II hypertensives.
