Despite reforms in mathematics education, many teachers remain reluctant to incorporate challenging (i.e., more cognitively demanding) tasks into their mathematics instruction. The current study examines how lesson structure shapes teacher perceptions of teaching with challenging tasks. Participants included three Year 1/2 classroom teachers who…

This study presents students' feedback and learning impact on design and development of a multimedia learning in Direct Problem-Based Learning approach (mDPBL) for Computer Networks in Dian Nuswantoro University, Indonesia. This study examined the usefulness, contents and navigation of the multimedia learning as well as learning impacts towards…

Achieving fluency in important mathematical procedures is fundamental to students' mathematical development. The usual way to develop procedural fluency is to practise repetitive exercises, but is this the only effective way? This paper reports three quasi-experimental studies carried out in a total of 11 secondary schools involving altogether 528…

Development assessment and remedial needs to be done because it is an important part of a learning process. This study aimed to describe the ability of student teachers of biology in developing assessment and remedial based on local wisdom. using a quasi-experimental research methods with quantitative descriptive analysis techniques. The research…

Metacognitive knowledge is a necessity in starting learning process. Solving physics problems requires metacognitive knowledge which comprises factual, conceptual and procedural knowledge. The purpose of metacognitive knowledge is to train students in developing their abilities in higher order of thinking. The problem is what kind of strategies…

This study presents a method for teaching the subject of chemical equilibrium in which students engage in self-learning mediated by the use of a new multimedia animation (SEQ-alfa©). This method is presented together with evidence supporting its advantages. At a microscopic level, the simulator shows the mutual transformation of A molecules into B…

The implementation of KKNI curriculum in Indonesia requires meaningful learning--so does the biochemistry learning. In the mean time, biochemistry learning is constrained by the fact that its implementation and assessment have yet to be integrated with classroom learning and laboratory works. The Orientation/Decision/Do/Discuss/Reflect (OD3R)…

The authors' objective was to study the role of error detection and retroactive self-regulation as determinants of performance in secondary education students. A total of 198 students participated in the quasiexperimental study, which involved a control group and two experimental groups. This enabled the authors to analyze the effects of both…

Gifted children are a special group within the scope of the special education so it is needed to be used by a number of special techniques and teaching methods. However, most teachers do not receive any training about gifted students. This situation-teachers lack of necessary education can cause gifted students to underachieve or quit the school.…

This quasi-experimental study examined the potential benefits of zero-error dictation, a teaching technique based on dialogue-driven dictation, and the extent to which target linguistic features and proficiency levels mediated its effects on second language (L2) learners' accurate use of French grammatical morphology. Seventy-nine learners of L2…

The purpose of this study is to investigate the effects of using geometric functions approach on 9th grade students' motivation levels toward mathematics in functions unit. Participants of this study were 87 students who were ongoing in the first year of high school in Turkey. In this research, pretest and posttest control group quasiexperimental…

Various forms of pre-listening support, such as the provision of vocabulary and topic information, have been used to help second language (L2) learners better understand what they listen to. Results of studies on the effects of vocabulary support have been mixed. Furthermore, there has been little research on the effects of different quantities of…

Direct instruction approach has been widely used in higher education. Many studies revealed that direct instruction improved students' knowledge. The characteristics of direct instruction include the subject delivered through face-to-face interaction with the lecturers and materials that sequenced deliberately and taught explicitly. However,…

The purpose of this study was to examine the effects of using 'hands-on' models (HOMs) to teach the subject of seasons--a topic about which students often have misconceptions--on students' expressed models. To this end, three different HOMs were developed. The study sample consisted of 80 seventh graders (ages 12-13). The study had a…

The aim of this study is to examine difference in the effect of instructional methods (lecture-discussion versus group discussion) and teaching talent on teacher trainees student learning outcomes. It was conducted by a quasi-experimental design using the factorialized (2 x 2) version of the nonequivalent control group design. The subjects were…
