Scalable Science Education via Online Cooperative Questioning

How can the scalable powers of peer learning and online technologies be most effectively used to support conceptual understanding in science education? This paper reviews cognitive science research on how people learn via question answering and authoring and evaluates a promising novel learning design that applies these principles.

Student Performance on the BDSI for Basic Data Structures

A Concept Inventory (CI) is an assessment to measure student conceptual understanding of a particular topic. This article presents the results of a CI for basic data structures (BDSI) that has been previously shown to have strong evidence for validity. The goal of this work is to help researchers or instructors who administer the BDSI in their own courses to better understand their results. In support of this goal, we discuss our findings for each question of the CI using data gathered from 1,963 students across seven institutions.

Analyzing Student Problem-Solving With MAtCH

Problem-solving has been recognized as a critical skill that students lack in the current education system, due to the use of algorithmic questions in tests that can be simply memorized and solved without conceptual understanding. Research on student problem-solving is needed to gain deeper insight into how students are approaching problems and where they lack proficiency so that instruction can help students gain a conceptual understanding of chemistry. The MAtCH (methods, analogies, theory, context, how) model was recently developed from analyzing expert explanations of their research and could be a valuable model to identify key components of student problem-solving. Using phenomenography, this project will address the current gap in the literature of applying the MAtCH model to student responses. Twenty-two undergraduate students from first-year general chemistry and general physics classes were recorded using a think-aloud protocol as they worked through the following open-ended problems: 1) How many toilets do you need at a music festival? 2) How far does a car travel before one atom layer is worn off the tires? 3)What is the mass of the Earth’s atmosphere? The original definitions of MAtCH were adapted to better fit student problem-solving, and then the newly defined model was used as an analytical framework to code the student transcripts. Applying the MAtCH model within student problem-solving has revealed a reliance on the method component, namely, using formulas and performing simple plug-and-chug calculations, over deeper analysis of the question or evaluation of their work. More important than the order of the components, the biggest differences in promoted versus impeded problem-solving are how students incorporate multiple components of MAtCH and apply them as they work through the problems. The results of this study will further discuss in detail the revisions made to apply MAtCH definitions to student transcripts and give insight into the elements that promote and impede student problem-solving under the MAtCH model.

I Be Africa Man Original: Towards a Contextual Conceptualization of Father Involvement in the Education of Children with Disabilities in Kenya

Father involvement could play a significant role in the lives of children with disabilities. Research is scarce on father involvement in the education of children with disabilities in Africa. We seek to provide a context for father involvement in the formal education of children with disabilities in Kenya, with the aim of contributing to the development of a conceptual understanding for father involvement in such a circumstance. We examine general research on father involvement in Kenya, explore the policy frameworks that guide fatherhood in the country, and look at the specific area of involvement in education. We then present a case study that examines father involvement in the formal education of children with disabilities in Kenya. Our analysis flags up a key opportunity in the pursuit of education for children with disabilities when fathers are involved; they can support their children with disabilities’ access, participation and success in education. We highlight the need for research that builds upon the voices of fathers to illuminate their role in education and we also make some suggestions toward a conceptual lens that will highlight the contextual realities involved, particularly in regard to the education of children with disabilities.

Creative Mathematical Reasoning: Does Need for Cognition Matter?

A large portion of mathematics education centers heavily around imitative reasoning and rote learning, raising concerns about students’ lack of deeper and conceptual understanding of mathematics. To address these concerns, there has been a growing focus on students learning and teachers teaching methods that aim to enhance conceptual understanding and problem-solving skills. One suggestion is allowing students to construct their own solution methods using creative mathematical reasoning (CMR), a method that in previous studies has been contrasted against algorithmic reasoning (AR) with positive effects on test tasks. Although previous studies have evaluated the effects of CMR, they have ignored if and to what extent intrinsic cognitive motivation play a role. This study investigated the effects of intrinsic cognitive motivation to engage in cognitive strenuous mathematical tasks, operationalized through Need for Cognition (NFC), and working memory capacity (WMC). Two independent groups, consisting of upper secondary students (N = 137, mean age 17.13, SD = 0.62, 63 boys and 74 girls), practiced non-routine mathematical problem solving with CMR and AR tasks and were tested 1 week later. An initial t-test confirmed that the CMR group outperformed the AR group. Structural equation modeling revealed that NFC was a significant predictor of math performance for the CMR group but not for the AR group. The results also showed that WMC was a strong predictor of math performance independent of group. These results are discussed in terms of allowing for time and opportunities for struggle with constructing own solution methods using CMR, thereby enhancing students conceptual understanding.

CONCEPTUAL UNDERSTANDING OF TRANSVERSE MYELITIS IN AYURVEDA: A CRITICAL REVIEW

Transverse myelitis (TM) is a rare neurological disease of spinal cord inflammation. Onslaught inflammation damage the myelin is leading to nervous system scaring. Consequently, the patient presents devastating neurological effects. It can afflict people of any age, gender or race. Symptoms per usual evolve over hours or days and then deteriorate over days to weeks. Symptoms include pain, sensory problems, weakness in the legs and arms, and bladder and bowel problems. Most people partially recover within three months; others may be permanently disabled. There is no cure for TM thus far, but neurological deficit can be minimised. From the purview of Ayurveda, TM can be categorised under the spectrum of Vata disorder. Recent research report the successful treatment of TM. However, each explains the pathology differently. This review will discuss the concepts of TM apropos to Mishravarana (combined occlusion) and its management. We suggest that symptoms and pathology of TM simulate closely with Avaranajanya Vatavyadi (disease of Vata due to occlusion). Mishravarana (combined occlusion) illustrates the complexity of the disease process involved.
