Effectiveness of a Short,Intense Bridging Course for Scaffolding Students Commencing University-level Study of Chemistry

Bridging courses designed to support students commencing tertiary education are widespread, and some evidence for the value of semester-length courses has been reported; however, little attention has been paid to short-but-intense bridging courses, and empirical evidence of their effectiveness is particularly sparse. The current study followed the academic performance of a cohort of students enrolled in a first-year chemistry unit of study designed for those with little or no background knowledge of chemistry. The aims of this study are two-fold: first to determine the strength of the linkage between prior knowledge in chemistry and performance on the end of semester exam, and secondly, to explore the reasons for any differences observed. In particular, the value of the week-long intensive-mode bridging course offered by the University of Sydney was analysed. Quantitative and qualitative data were collected. The research has shown that participation in the chemistry bridging course is associated with ‘bridging the gap’ in academic performance between students with No Prior Chemistry background and those with a Strong Background. While the content of the bridging course is a significant contributor to academic success, so too is the confidence in their own learning that the course engenders among participants.     

Adapting Science and Technology Education to a Changing Society and to the Diversity of Needs of Arab States

Summaries

English

Science is being increasingly considered as a social activity that must be harnessed to serve human needs. In many developing countries, science and technology education tend to replicate practices in advanced countries. The challenges of responding adequately to the solution of the problems of society and of meeting the different needs of a country or a region have not been realized. The accelerated social and technological changes that are taking place in many Arab states intensify the variety of problems that have been cited. The guidelines suggested towards adapting education to the state's needs and towards overcoming the problems include: emphasizing the development of intellectual and occupational skills which are significant, retainable, and transferable to everyday life; developing respect for manual skills; revising curricula to introduce topics relevant to society; and making efforts towards developing the home environment and the community.     

‘Do You Have to Pack?’—Preparing For Culturally Relevant Science Teaching in the Caribbean

This paper reports on the attempts by some Caribbean science teachers to make links between their students' everyday lives and school science in their planning for teaching. It describes how these teachers drew on their exposure to a university graduate course on science education and culture in seeking to access the background cultural knowledge of their students and to incorporate this knowledge in their plans for teaching science. The paper critically examines the experiences of these teachers and highlights both the rewards and challenges that ensued as these teachers prepared for culturally relevant science teaching     

The use of augmented reality games in education: a review of the literature

This paper provides a review of the literature about the use of augmented reality in education and specifically in the context of formal and informal environments. It examines the research that has been conducted up to date on the use of those games through mobile technology devices such as mobile phones and tablets, both in primary and secondary education. The review of the relative literature was carried out in the period 2000 to early 2014 in ScienceDirect and ERIC. The outcomes of this review illustrated a set of studies that provide evidence of positive outcomes regarding student learning. These studies, which focused mainly on the natural sciences and took place within informal learning environments, used both qualitative and quantitative data collection methods. The earliest study that was conducted about this topic used personal digital assistants, while the more recent one used smart (mobile) phones and tablets. The services of augmented reality focused on markers/quick response codes, virtual items, global positioning system services as well as on platforms for game creation. The findings of the literature review are discussed in relation to research approaches that are needed for augmented reality games to be played either in formal or informal learning environments.     

Examining activity-based learning (ABL) practices in public basic schools in the northern region of Ghana

Background: Ghana has been the testing ground for many teaching and learning initiatives over the past 15–20 years. These initiatives, largely funded by donors, have sought to improve learning by introducing and reinforcing valuable teaching skills, materials and approaches, most of them child-friendly, learner-centred and involving activity-based learning (ABL). However, a problem in Ghana, also true of other countries in sub-Saharan Africa, is that whereas efforts over the past few decades have improved access to basic education in both pupil enrolment rates and teacher numbers, educational quality as measured by standardised test scores in key subject areas remains rather low.

Purpose: This article reports on an aspect of a DfID (Ghana) – sponsored research project which examined how the quality of teaching and learning in Ghanaian basic schools could be improved through the utilisation of ABL pedagogy. The current article examines three overarching themes relative to ABL pedagogy, namely how participants conceptualise ABL; ways in which ABL practices reveal themselves in classrooms; and challenges of ABL practices in Ghanaian schools.

Sample: Participants (comprising representatives of Colleges of Education, District Directors and frontline Deputy Directors of Education, headteachers and teachers) were drawn using purposive sampling technique from eight schools from within four districts of the northern region of Ghana.

Design and Methods: A case study approach was adopted for the study. Data collection took the form of semi-structured interviews, focused group discussions and observation of ABL practices and lessons in selected schools. Data analysis was undertaken using a ‘processual analytical approach’ with the view to catching realities of ABL practices in the Ghanaian educational setting.

Results: Our analysis reveals that whereas the literature on ABL emphasises multi-tasking and group work as essential ingredients of ABL pedagogy, the respondents conceptualised this as meaning pupils working on the same activity-related tasks at the same time in groups. Similarly, we found that, ideally, ABL practices reveal themselves through classroom practices such as display of pupils’ work in classrooms, organisation of the seating arrangements of pupils in groups, use of teaching and learning materials, formative assessment and activity-oriented lessons among others. However, in almost all the schools and classrooms we visited, these essential ingredients were missing owing to congestion and lack of furniture and logistics.

Conclusions: We conclude against the backdrop of our findings that ABL techniques can be utilised more effectively in Ghanaian schools if its practices are initially promoted in model schools, for lessons to be learned, and then scaled-up as expertise is established in these model schools.     

How secondary level teachers and students impose personal structure on fractional expressions and equations—an expert-novice study

While an algebraic expression is typically assigned a regular structure, this article introduces the concept of personal structure (Strukturierung); here, the structuring of an algebraic expression is understood as the act of forming relationships between its parts. This concept is used for the analysis of interviews in which experts and novices talk about the personal structures they produced when looking at fractional expressions and equations. The results show, firstly, that experts will structure a given fractional expression in various different ways. Secondly, four categories have been identified: structuring can mean that an expression is made more visually straightforward, changed, reinterpreted or classified. This is meaningful for negotiating the appropriateness of the personal structures in teaching algebra.     

Strategies for success: uncovering what makes students successful in design and learning

While the purposes of design and science are often different, they share some key practices and processes. Design-based science learning, which combines the processes of engineering design with scientific inquiry, is one attempt to engage students in scientific reasoning via solving practical problems. Although research suggests that engaging students in design-based science learning can be effective for learning both science process and content, more research is needed to understand how to overcome what Vattam and Kolodner (Pragmatics and Cognition 16:406–437, 2008) called “the design–science gap.” This study, therefore, takes a first step at systematically delving into this issue of bridging the design–science gap by examining the problem-solving strategies that students are using when they solve a prototypical design task. Videotaped performance assessments of high and low performing teams were analyzed in depth. Results suggest that students use both science reasoning strategies (e.g., control of variables) and design–focused strategies (e.g., adaptive growth). However, the strategies commonly associated with success in science (e.g., control of variables) did not necessarily lead to success in design. In addition, while both science reasoning strategies and design–focused strategies led to content learning, the content learned was different.     

Development of legal expertise

In a comprehensive empirical investigation (N = 71,405) we analyzed the development of legal expertise in a critical 1-year period of academic legal training in which advanced law students start practicing to solve complex cases. We were particularly interested in the functional form of the learning curve and inter-individual differences in learning. Performance increases monotonically with the number of practice exams following a slightly concave learning curve without any considerable kinks. Considering the performance development over time, however, the curve is not monotonic and shows intermediate drops in performance. We provide evidence which suggests that these drops are due to cyclic drops in motivation. There are about equally sized marginal effects of practicing law exams in general and practicing exams in the specific area of law. However, students with high (vs. low) initial performance profit more from practicing exams within a specific area of law whereas students with low initial performance profit more from practicing exams in general. The concave increase in performance with the number of practicing exams is mainly driven by individuals with low initial performance. Those with high initial performance mainly display a linear learning trend. We discuss the practical implications of these findings for academic legal training.     

Time in the arts and physical education and school achievement

With the increase in state‐mandated high‐stakes testing across the USA, schools and school districts are considering ways of increasing instructional time for core curricular subjects such as mathematics, science, English, and social studies. One seemingly logical approach to improving test scores is to reduce the time spent in subjects that are not tested, most notably art, music, and physical education, thus increasing time for the tested subjects. In this study, data was collected from 547 Virginia elementary school principals who completed a survey indicating the time specialists taught art, music, and physical education in their schools. After controlling for socio‐cultural opportunities associated with the school community, partial correlations between time allocation and school‐level passing rates on the Virginia Standards of Learning tests indicated no meaningful relationship between time allocation to art, music, and physical education and school achievement. The findings from the study do not support the notion that a reduced time allocation to art, music, and physical education is related to higher test scores.     

Unique Multiple Linear Regression Problems for Each Student

The purpose of this report is to describe a process for creating unique multiple linear regression problems for each student. Three formulas were utilized to define intercorrelations between variables. A computer program was written based upon these mathematical relationships. To test the power of the program to “select” a random sample from variables with defined interrelationships, eleven examples were tested. On 33 sample correlation coefficients the expected number of significant correlations, 1.65, was larger than the number observed, 1. No difficulty is expected in preparing such problems for each student in a statistics or a research methods course, where professors may find problems of this type to be helpful.
