In a previous study of the Child-Parent Centers (CPC) education program, preschool participation was linked to a 4.6 percentage point reduction (26%) in depressive symptoms at ages 22–24 over the matched comparison group enrolling the usual programs. The present study reanalyzed these data in the Chicago Longitudinal Study to address potential attrition bias since more than a quarter of the sample was missing on the outcome. Using inverse probability weighting (IPW) involving 32 predictors of sample retention, findings for the 1,142 participants growing up in high-poverty neighborhoods indicated that CPC participation was associated with a 7.1 percentage point reduction (95% CI = [−9.7, −5.4]) in one or more depressive symptoms (39% reduction over the comparison group). Although this marginal effect was within the confidence interval of the original study (95% CI = [−9.5, 0.3]), the 54% increase in the point estimate is substantial and of practical significance, suggesting underestimation in the prior study. Alternative analysis of different predictors and IPW models, including adjustments for program selection and attrition together, yielded similar results. Findings indicate that high-quality early childhood programs continue to be an important strategy for the prevention of depression and its debilitating effects on individuals and families.

Visuospatial Representation

Study of this research investigates the role of visuospatial representation using Wimba model to improve student’s conceptual mastery based on gender in learning Human Urinary System. The method used in this research was experimental research with matching pretest-posttest comparison group design. The sample was taken based on gender classes consisting of boys class (n=21) and girls class (n=9) in one of Bilingual School in Bandung. The quantitative data of this research was investigated through the objective test, while the supportive qualitative data gathered through Likert-Scale. The conceptual mastery of both classes measured based on Bloom’s taxonomy cognitive domain through an objective test. Data processing was done by independent sample t-test. The result of this research shows that there are significant differences in conceptual mastery improvement between girl class and boy class by using visuospatial representation as a model. The research indicates that girl class is outperformed in conceptual mastery almost in each cognitive domain than boy class, and girl class also shows more positive responses toward learning using visuospatial representation than boy class.

Penelitian ini bertujuan untuk mengetahui perbedaan pemahaman konsep dan pemecahan masalah pada materi KK3: (1) antara siswa yang diajar dengan pembelajaran kooperatif tipe Jigsaw II dan siswa dengan pembelajaran kooperatif tipe Group Investigation (GI) ketika motivasi belajar TKJ dikendalikan; dan (2) antara penggunaan tipe pembelajaran kooperatif (tipe Jigsaw II dan tipe GI) dengan tingkat motivasi belajar TKJ (tinggi dan rendah). Penelitian ini merupakan penelitian eksperimen semu dengan nonequivalent comparison-group design menggunakan dua kelas perlakuan sebagai variabel bebas yang diberikan pembelajaran kooperatif dengan dua tipe berbeda. Satu kelas menggunakan tipe Jigsaw II, sedangkan kelas yang lainnya diberikan tipe GI. Variabel motivasi belajar TKJ dijadikan sebagai pembagi kategori kelompok siswa yang memiliki motivasi belajar TKJ tinggi dan rendah serta sebagai kovarian. Teknik analisis data yang digunakan adalah analisis multivarian kovariat dan desain faktorial dengan progam SPSS 16. Artikel ini menunjukkan tujuan kedua, dengan hasil penelitian menunjukkan bahwa: (1) untuk pencapaian pemahaman konsep, pembelajaran kooperatif tipe Jigsaw II dan tipe GI baik diaplikasikan untuk siswa yang memiliki motivasi belajar TKJ tinggi dan rendah, akan tetapi untuk siswa yang memiliki motivasi belajar TKJ rendah lebih baik menggunakan tipe GI; dan (2) untuk pencapaian pemecahan masalah, pembelajaran kooperatif tipe Jigsaw II dan tipe GI baik diaplikasikan untuk siswa yang memiliki motivasi belajar TKJ tinggi, siswa yang memiliki motivasi belajar TKJ rendah maupun siswa yang memiliki motivasi belajar TKJ tinggi lebih baik menggunakan tipe GI. Kata  THE DIFFERENCES OF JIGSAW II AND GI ON THE CONCEPT UNDERSTANDING AND PROBLEM SOLVING IN COMPETENCE OF DIAGNOSING PROBLEMS WHEN OPERATE PC AND PERIPHERAL IN TERMS OF LEARNING MOTIVATIONAbstractThis research aims to describe the differences of concept understanding and problem solving on the KK3 material: (1) between students taught using the cooperative learning Jigsaw Type II and GI Type when TKJ learning motivation was controlled; and (2) between the use of cooperative learning (Jigsaw Type II and Group Investigation (GI) Type) with the levels of TKJ learning motivation (high and low). This research was quasi-experimental with the nonequivalent comparison-group design using two treatment classes as independent variables which were given cooperative learning with two different types. One class used the Jigsaw Type II while the other used the GI Type. The TKJ learning motivation was used as the divider category of students who have high and low TKJ learning motivation as well as covariant. The data analysis technique in this research was the multivariat analysis of covariate and factorial design using the SPSS 16 program. This article shows the second aim, and the results shows that: (1) for concept understanding achievement, cooperative learning Jigsaw Type II and GI Type are good to be applied for students who have high and low TKJ learning motivation, but for those who have low TKJ learning motivation, GI Type is better than Jigsaw Type II; and (2) for problem solving achievement, cooperative learning Jigsaw Type II and GI Type are good to be applied to students who have high TKJ learning motivation, where for those who have high and low TKJ learning motivation GI Type is better than Jigsaw Type II.
