This paper has proposed to investigate the interest in students towards physics among other science subjects. The investigation was carried out with 490 samples of grade ten students in Wolaita Soddo town governmental schools. Thus, overall result indicates that the interest in students towards physics is low and students hate to learn physics in…

This article describes revisions to four of the eight constructs of the Duncan molecular genetics learning progression [Duncan, Rogat, & Yarden, (2009)]. As learning progressions remain hypothetical models until validated by multiple rounds of empirical studies, these revisions are an important step toward validating the progression. Our…

Representations are often used in instruction to highlight key mathematical ideas and support student learning. Despite their centrality in scaffolding teaching and learning, most of our understanding about the tasks involved with using representations in instruction and the knowledge requirements imposed on teachers when using these aids is…

In South Africa, inequalities endemic to HE systems worldwide are further compounded by apartheid legacies. Despite an intensive focus for over twenty years on how pedagogic intervention could be harnessed to address these inequalities, black students' participation and success rates in South African HE remain stubbornly low, suggesting a need for…

Over the last two decades, the education system has witnessed a shift from summative, product-oriented assessment towards formative, process-oriented assessment. Among the different learning and assessment initiatives introduced in the slipstream of this paradigmatic turn, the portfolio seems to have become one of the most popular. By redescribing…

Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

The task of turning undergrads into academics requires teaching them to reason about the world in a more complex way. We present the Argument Complexity Scale, a tool for analysing the complexity of argumentation, based on the Integrative Complexity and Conceptual Complexity Scales from, respectively, political psychology and personality theory.…

The current paper reports an experience implementing a small-scale narrow listening scheme (one of the varieties of extensive listening) with intermediate learners of English as a foreign language in a Colombian university. The paper presents (a) how the scheme was designed and implemented, including materials and procedures (the process); (b) how…

The aim of the research was to identify how Slovenian primary and secondary school students of various age groups explain the particulate nature of the states of matter of water and air. The qualitative research included five 12, 14, and 16 year old students. A semi-structured interview including four computer-displayed tasks was used for the data…

Students' perceptions are one of the sources that can be used to capture teachers' PCK. Therefore, the aim of this study was to develop a scale to determine secondary students' perceptions of their teachers' PCK. Validity and reliability studies were conducted with 659 students. Both exploratory factor analysis and confirmatory factor analysis…

An Oral Proficiency Interview (OPI) may be evaluated either during the interview procedure (direct-method) or from a tape-made oral interaction (semi-direct method). Such variety in methods of assessment can influence test takers' scores extensively. However, it is not conclusive whether such differences are due to test format or something else.…

Elementary school students are often placed into groups with peers of similar reading ability in a practice called within-class ability grouping for guided reading instruction. Through this practice, students are differentially exposed to reading skills, strategies, and texts that are presumed to match their current level of ability. This…

The goal of this meta-analysis is to evaluate how instructional technology has impacted advanced second language (AL2) development. Although numerous metaanalyses have been conducted within the CALL literature over the past two decades, they primarily focus upon learning outcomes and related effect sizes. None focus on advanced learning per se.…

Despite an increased awareness of language learner performance in task-based instruction, little is known about how learners perceive and respond to different task factors. This study investigates the effects of task complexity and modality on (a) learners' perception of task difficulty, skill, and its balance, and on (b) learners' task…

This study replicated, with modifications, previous research of dyad reading using texts at various levels of difficulty (Morgan, 1997). The current project measured the effects of using above-grade-level texts on reading achievement and sought to determine the influences of dyad reading on both lead and assisted readers. Results indicate that…
