Textbooks are one of the main resources for teaching and learning mathematics. This study examines the presentation of angle topics in 4th-grade mathematics textbooks in Indonesia and Singapore. The analysis focused on the general characteristics of the textbook and the nature of the mathematical tasks presented. The results showed that Indonesian…

This study aims to reconstruct Grade 11 students' misconceptions about force through the Conceptual Change Model (CCM) making use of Predict, Discuss, Explain, Observe, Discuss, Explore, Explain (PDEODEE) tasks. This study was conducted using a mixedmethod approach. The participants in this study were 65 students (33 students in the experiment…

This study examined how Chinese native speakers (NSs) and second language (L2) learners process compound words. The findings showed that they used the hybrid model of coexistence for whole word and morphemes; and were influenced by word frequency, semantic transparency, and word structure. The results revealed that two groups of participants used…

This paper explores the spatial dimension of Fleming's Left Hand Rule (LHR), commonly-used in Physics instruction for determining the direction of force using the left hand's thumb, forefinger and middle finger. A new instrument was developed to gauge students' ability to coordinate their fingers in 3D space (egocentric frame of reference) based…

Background: The worked example effect in cognitive load theory suggests that providing worked examples first followed by solving similar problems would facilitate students' learning. Using problem solving-worked example sequence is another way of implementing example-based instruction. Although research has demonstrated the superiority of worked…

Students' spatial ability plays an important role in instruction with dynamic and static visualizations. This research was aimed at describing 1) the difference in learning achievement between the students who learned from dynamic visualization and static visualization, 2) the difference in learning achievement among students who have high spatial…

As an intervention program developed to accelerate participant cognitive development, the effect of Cognitive Acceleration through Science Education (CASE) implementation in certain conditions needs to be clarified. This paper describes the effect of CASE program to the cognitive development of elementary students in Indonesia. The study used a…

This study investigated the effects of two types of classroom instructions on EFL learners' oral proficiency by implementing teachers' judgment. Two intact classes of EFL university students studied a compulsory subject of their department under two different types of classroom instruction. The first group of students was trained with explicit…

Integrating Task-Based Language Teaching (TBLT) and learning technologies can be the potential framework in designing language instruction to enhance learners' listening comprehension and speaking performance. However, not many past studies have explored how technology enhanced TBLT can enhance both listening comprehension and speaking performance…

In the beginning of the first decade of this century, some highly-publicized extremistic acts of terror occurred. A hostage tragedy in a school in Beslan (North Ossetia) was followed in the Netherlands by the brutal murder of the controversial Dutch filmmaker and newspaper columnist Theo van Gogh, bomb attacks in Bali and Madrid and other acts of…
