The diversity of scientific methods has received widespread attention and recognition in recent years. Brandon's Matrix illustrated four categories of scientific methods, which was applied to establish the analytical framework of this study. This paper adopted content analysis to investigate how the diversity of scientific methods is represented…

This study contributes to the call for influencing practice by increasing attention to how learning environments can be designed to support learning in statistical inference. We report on a design experiment in secondary school (students 14-16 years old), that resulted in a set of lessons with the learning goal of teaching students how to apply…

To test the hypothesis that a higher tendency to "s"pontaneously "f"ocus "o"n "m"ultiplicative "r"elations (SFOR) leads to improvements in rational number knowledge via more exact estimation of fractional quantities, we presented sixth graders (n = 112) with fraction number line estimations and a…

This article illustrates ways that dynamic software using some sophisticated techniques in Excel can be used to demonstrate fundamental ideas related to hypothesis testing to increase student understanding of the concepts and methods in elementary statistics courses. The article considers hypothesis tests for the population mean with large or…

This article recounts the author's working experience of one method by which pupils' understanding of the epistemologies of science can be developed, specifically how scientists can develop hypothetical models and test them through simulations. She currently uses this approach for transition lessons with pupils in upper primary or lower secondary…

The purpose of this study was two-fold. First, this study examined the difference in the State of Texas Assessments of Academic Readiness [STAAR's] academic achievement (Math, Science, Reading and Writing) scores of secondary students by instructional status (Single teaching and Co-teaching). Second, this study investigated the predictability of…

Many large-scale, school-based interventions have attempted to improve academic performance through promoting students' growth mindset, defined as the belief that one's intellectual ability can increase with practice and time. However, most have shown weak to no effects. Thus, it is important to examine how growth mindset might affect retention…

This study focused on the influence of psychosocial factors on job performance of female teachers in Kwara State, Nigeria. The study also examined the variables of age, level of education and length of years in service. The descriptive survey was adopted for the study. A total sample of 400 respondents was selected in Kwara State, using the simple…

The purpose of this study was to determine teachers' approaches to Marzano's effective instructional strategies (MEISs), as defined by Marzano, Pickering and Pollack (2001) in the secondary schools in Turkey and Russia and tell whether they differ or not. In this study survey research - one of the quantitative approaches -- was carried out. The…

This study was carried out to determine the effect of guided inquiry teaching method (GITM) on secondary school students' achievement in light and sound waves in Abuja, Nigeria. A sample of 95 students drawn from a population of 1,832 was used for the study. Two research questions were raised and answered in the study using mean and standard…

In recent years, the ability to use mathematics flexibly in everyday situations is increasingly accentuated, and mathematics education gives more and more attention to problems with realistic contexts. However, it is reported very often that learners have substantial difficulties in connecting mathematics to real situations. In order to solve…

Worked examples and collaborative learning have both been shown to facilitate learning. However, the testing of both strategies almost exclusively has been conducted independently of each other. The main aim of the current study was to examine interactions between these 2 strategies. Two experiments (N = 182 and N = 122) were conducted with…

Avogadro's conception of the structure of gases was not widely accepted by his contemporaries--probably because the hypothesis was not supported by direct evidence. This problem is rarely addressed in schools. This article discusses the difficulties that accompany the acceptance of new ideas. Such difficulties may be associated with the ways in…

In this article, Strayer and Matuszewski present a six-phase strategy that teachers can use to help students develop a conceptual understanding of inferential hypothesis testing through simulation. As Strayer and Matuszewski discuss the strategy, they describe each phase in general, explain how they implemented the phase while teaching their…

Assimilating multiple interactive elements simultaneously in working memory to allow understanding to occur, while solving an equation, would impose a high cognitive load. "Element interactivity" arises from the interaction between elements within and across operational and relational lines. Moreover, operating with special features…
