New teachers struggled to learn as the pandemic interrupted in-person teaching rehearsals

Instructors of an undergraduate course teaching instructional methods to future secondary science teachers conducted a qualitative study analyzing the experience of suddenly switching teaching rehearsals to an online format. Half of the fifteen preservice teachers in the course were able to practice being teachers in in-person rehearsals with peers before the course switched to a virtual format in March 2020. The other half were only able to practice in rehearsals online. Little consensus exists on how best to teach pedagogical methods for rigorous and equitable teaching. Macroteaching is a format that entails 11-12 hours of practice teaching to peers as if teaching a full unit to a class of secondary students. These extended opportunities for rehearsal, feedback, and collaborative reflection are intended to build preservice teachers’ pedagogical skills and instructional vision, making it more likely that new teachers will attempt techniques for rigorous and responsive teaching in the first few...

The link between teacher-student relationship and academic achievement in China

In a recent study published in School Psychology International, Lei and colleagues conducted a three-level meta-analysis to investigate the relationship between teacher-student relationships (TSR) and student academic achievement (SAA) in China. The authors believed the positive link between TSR and student academic achievement is higher in hierarchical, collective China than egalitarian, individualistic western society as teachers have greater authority in China than in Western societies, and teachers are often the centre of TSR. With the greater respect of authority among Chinese students, the link between TSR-SAA could be higher compared to Western countries. The study included 74 studies (90 effect sizes) that examined the TSR-SAA correlation in the Chinese context published between 2002 and 2020 which involved both primary school and secondary school students. The results found Overall, significant positive correlation between teacher-student relation and student academic achievement (r = 0.26) was found among Chinese studies, which is larger than...

How consistent are the meanings of “evidence-based” in program effectiveness evaluation?

“Evidence-based,” a currently popular concept, assumes that identifying the high-quality interventions with valid positive results will enhance educational outcomes on a widespread scale. Clearinghouses (CHs) push this process forward by setting their chosen scientific criteria, evaluating studies of the required quality, synthesizing the study results, and proposing recommendations. To probe into the consistency of the meanings of “evidence-based” in different CHs, Cook and colleagues recently examined 12 educational clearinghouses to (1) compare their effectiveness criteria, (2) estimate how consistently they evaluate the same program, and (3) analyze why their evaluations differ. How variable are CHs in their effectiveness criteria? All the CHs value randomized control trials (RCT) as the preferred experimental design, but they vary in how they test whether an RCT is well-implemented enough to deserve the highest study-quality ranking. Quasi-experimental designs were treated more variably than RCTs based on separate standards for different categories. Additionally, different CHs place...

A high-dosage tutoring program facilitates reading achievement of beginning readers

The latest National Assessment of Educational Progress (NAEP) (2019) indicates that 65% of fourth graders in the U.S. do not show proficiency in reading. Given that reading skills in kindergarten and first grade have been demonstrated by many studies to be critical to students’ academic success and societal achievements, there is an urgent demand for interventions that effectively facilitate young children’s acquisition of reading skills. Recently, a study was conducted to examine the effect of a one-on-one high-dosage tutoring program, Chapter One, on kindergarten and first grade learners. Chapter One provides students who struggle to read with paraprofessional tutors who help them develop their literacy skills via digital applications. This study involved 185 kindergarten and first grade students in an Ohio Title 1 school, who were randomly assigned to the treatment group, who received both teacher instruction and Chapter One tutoring 2-3 times per week during school days, or the...

Excellence gaps and equity in education

Differences in achievement levels among subgroups of students are referred to as “excellence gaps,” which primarily concern the highest-performing students. While certain students may struggle to attain the minimum expected levels of academic achievement, there are others who are already performing at levels beyond their current grade before the beginning of the school year. Excellence gaps are connected to equitable school systems. Often students from disadvantaged socio-economic backgrounds have less access to advanced learning opportunities than their peers. A recent systematic review included qualitative and quantitative studies to determine what kind of research has been conducted on strategies to reduce excellence gaps in K-12. The review included 80 studies categorized by strategy, such as school accountability system support, teacher professional learning, and universal screening with local norms. The review highlighted the role of each strategy in reducing excellence gaps. Overall, results suggested considering four key points: Prepare, Place, Evaluate, and...

Early learning opportunities of migrant children in China

In China, over millions left-behind children who remain in their hometown while their parents have migrated from rural to cities for work. Due to household registration system (hukou), children of rural area are not entitled the basic welfare and public services in urban cities, including enrolment in public funded preschools. Research has found that simulating home learning environment and access to high quality preschool are more likely to enhance developmental advantages. A recent study by Gong and Rao investigated impact of internal migration on early learning opportunities of preschool children and they classified children into five categories: Rural children from non-migrant family with both parents (non left-behind rural children) Rural children left-behind with one parent Rural children left-behind without parent and looked after by relatives Rural children who had migrated along with parents to urban areas (migrant children) Urban native children (urban children) The authors performed selective pairwise comparison among...

Can e-books foster children’s language development in early education and care?

Language abilities in the early years have a long-lasting influence on children’s learning in school and later life. However, a considerable number of children enter school with weak language skills. Because e-books are increasingly considered an effective tool to narrow the gap, a meta-analysis published in the Educational Research Review investigated the effects of e-books on language support in early childhood education and care (ECEC). The meta-analysis evaluated the effectiveness of e-book reading in ECEC on children’s language development in comparison to two conditions: regular childcare without e-books, and print book reading in classrooms. After reviewing the studies published between 2000 and 2018 in English or German, the review identified 17 studies that met the inclusion criteria, such as involving at least 10 children, consisting of typically-developing and at-risk children (excluding children with developmental disorders), and using the society-spoken language (excluding a foreign language). Results indicated that e-book reading in...

Absences negatively impact achievement, regardless of the reason

Researchers from Scotland have added to the body of existing research on the negative effects of student absenteeism by exploring whether the reasons for absences have differing impacts on achievement. The study used linear regression to analyze longitudinal data from a representative sample of 4,419 students. Schools in Scotland are required to note the reason for student absences. Researchers compared this data with results from two high-stakes tests that students take in secondary school. Their study found: Overall absences, as well as absences due to vacations, were associated with a 0.03 standard deviation decrease in achievement (SE= 0.00, p< .01). Truancy- or sickness-related absences were associated with a 0.04 standard deviation decrease in achievement (SE= 0.00, p< .001). Family emergency-related absences were associated with a 0.02 standard deviation decrease in achievement (SE= 0.00, p< .01). Although this may not sound like a big effect, this actually represents more than a...

The relation between statistical learning and dyslexia

Human beings possessed a remarkable ability to unconsciously detect and internalize statistical patterns of sensory input from the environment, such as frequency, variability, and co-occurrence probability. This ability, known as statistical learning which is believed to be related to language acquisition. Researchers have investigated the link between statistical learning and developmental dyslexia (DD), a difficulty in learning to read even with normal intelligence and schooling, however, the results were mixed. Lee and colleagues conducted a meta-analysis compared the differences in statistical learning ability between people with developmental dyslexia (DD) and their age-matched typically development (TD) counterpart and investigate various factors which may affect the extent of differences. One of the factors was the statistical learning task paradigm which included: Serial reaction time (SRT) task: to measure the reaction time to randomly and sequentially ordered stimuli. This is an implicit learning that participant becomes familiar with a repeated sequence from mere...
