Initial Study of Students' Critical Thinking Ability Level and Concept Mastery on Earth Structure Material

Critical thinking and concept mastery is an important ability for every student to have. So, educators need to get information about the level of skills possessed by student. This study aims to describe the initial level of critical thinking skills and mastery of students' concepts, as well as the relationship between critical thinking skills and mastery of students' concepts on earth structure material in class VIII at SMP Negeri 2 Namang. The methodology used in the research is descriptive quantitative, using a critical thinking ability test and concept mastery test, and qualitative, using interviews. Students' critical thinking and concept mastery tests showed an average score of 43.78 and 55.94, with a fairly low category. The average value of the inference indicator was 25.97, and the indicator of making further explanations was 37.01. Both are the lowest indicators that still need to be improved. In contrast, the average value of the strategy and tactics indicator is 73.95, which is in the high category. The significance value obtained is <0.001, which indicates that there is a strong, significant, and directly proportional relationship between critical thinking skills and concept mastery, with a correlation coefficient value of 0.803. The results of the interview show the low enthusiasm of students in learning the structure of the earth due to the lack of a variety of media used and test questions that are not used to being done.

Targeting Phonology or Semantics to Improve Reading Aloud Response Times and Accuracy: A Case Series Investigation of Stroke Survivors With Aphasia.

Acquired reading deficits, or alexia, affect a significant proportion of individuals with aphasia. We sought to improve treatment for alexia by targeting specific cognitive information-processing components critical to reading (i.e., phonology or semantics). To target either phonological or semantic processing, we administered two anomia treatments, phonomotor treatment (PMT) and semantic feature analysis, modified to include a focus on reading throughout the therapy. Chronic left-hemisphere stroke survivors (N = 5) completed one or two 60-hr treatment rounds. Based on predictions from a computational reading model, three participants received the treatment recommended for their specific reading challenges (e.g., PMT for phonological deficits), while two participants had the nonrecommended treatment first, followed by the recommended model-matched treatment. Changes in reading aloud accuracy and response times (RTs) from before to after treatment were examined as a function of matching treatment to the deficit profile, type of treatment, therapy round, and word characteristics. Participants' reading aloud accuracy improved after treatment relative to baseline with higher accuracy for high-frequency words and shorter words. After the first treatment round, participants' accuracy and RT improved, irrespective of whether treatment was matched to the deficit profile. Furthermore, participants who completed the second treatment round continued achieving accuracy gains. Following treatment, participants demonstrated enhanced reading efficiency and generalized improvements on the selected sections of the Woodcock Reading Mastery Test. While larger studies are needed to test for the effects of matching treatment type to the deficit profile, we conclude that treatments targeting specific information-processing components can effectively improve reading. Doubling the treatment dose offers small but significant gains. https://doi.org/10.23641/asha.26517319.

A longitudinal study of the efficacy of the Cellfield reading intervention in a South African context

ABSTRACT The Cellfield reading intervention is based on the multi-deficit theory of reading difficulties and addresses several foundation skills of reading simultaneously. Existing research has confirmed that the Cellfield intervention leads to improvement in reading skill directly following the intervention, but little data exist to determine the long-term efficacy of Cellfield. The present study investigated the long-term efficacy of the Cellfield intervention in a group of South African children. Fifty-two struggling readers were assessed via two standardised tests (Woodcock Reading Mastery Tests and Gray Oral Reading Test). Of the 52 readers, 41 underwent the Cellfield intervention, while 11 did not. Children were assessed on six reading variables before the intervention and directly following the intervention (treatment group). Both groups were re-assessed on the same variables at least a year after the intervention ended. Statistical analyses showed that advances in the treatment group directly after the intervention were maintained in the long term.
